See # # https://cmake.org/cmake/help/latest/variable/CMAKE_BUILD_TYPE.html # # for information about debug or release builds, for example # # cmake -B build -D CMAKE_BUILD_TYPE=Release # # # For a dynamic library, use # # cmake -B build -D BUILD_SHARED_LIBS=true -D CMAKE_BUILD_TYPE=Release # # For a framework on OS X, use # # cmake -E chdir build cmake -G Xcode -D BUILD_FRAMEWORK:BOOL=true .. # # For an iOS static library, use # # cmake -E chdir build cmake -G Xcode -D IOS_PLATFORM=OS .. # # or # # cmake -E chdir build cmake -G Xcode -D IOS_PLATFORM=SIMULATOR .. # # or # # cmake -E chdir build cmake -G Xcode -D IOS_PLATFORM=SIMULATOR64 .. # # # Finally, build the project with # # cmake --build build # # Install it with # # (sudo) cmake --build build --target install # # A binary distribution can be made with # # cmake --build build --config Release --target package # # Please refer to the cmake manual for further options, in particular, how # to modify compilation and linking parameters. # # Some notes. # # - `cmake' creates configuration files in # # <build-directory>/include/freetype/config # # which should be further modified if necessary. # # - You can use `cmake' directly on a freshly cloned FreeType git # repository. # # - `CMakeLists.txt' is provided as-is since it is normally not used by the # developer team. # # - Set the `FT_REQUIRE_ZLIB', `FT_REQUIRE_BZIP2', `FT_REQUIRE_PNG', # `FT_REQUIRE_HARFBUZZ', and `FT_REQUIRE_BROTLI' CMake variables to `ON' # or `TRUE' to force using a dependency. Leave a variable undefined # (which is the default) to use the dependency only if it is available. # Example: # # cmake -B build -D FT_REQUIRE_ZLIB=TRUE \ # -D FT_REQUIRE_BZIP2=TRUE \ # -D FT_REQUIRE_PNG=TRUE \ # -D FT_REQUIRE_HARFBUZZ=TRUE \ # -D FT_REQUIRE_BROTLI=TRUE [...] # # - Set `FT_DISABLE_XXX=TRUE' to disable a dependency completely (where # `XXX' is a CMake package name like `BZip2'). Example for disabling all # dependencies: # # cmake -B build -D FT_DISABLE_ZLIB=TRUE \ # -D FT_DISABLE_BZIP2=TRUE \ # -D FT_DISABLE_PNG=TRUE \ # -D FT_DISABLE_HARFBUZZ=TRUE \ # -D FT_DISABLE_BROTLI=TRUE [...] # # - NOTE: If a package is set as DISABLED, it cannot be set as REQUIRED # without unsetting the DISABLED value first.

The `SVG_DOCUMENT_LIST_MINIMUM_SIZE` macro is non trivial and not protected by parentheses. As a result, the expression `table_size - SVG_DOCUMENT_LIST_MINIMUM_SIZE` expands to `table_size - 2U + SVG_DOCUMENT_RECORD_SIZE` instead of the expected `table_size - (2U + SVG_DOCUMENT_RECORD_SIZE)`. This causes an incorrect bounds check which may lead to reading past the end of the `SVG ` table. * src/sfnt/ttsvg.c (tt_face_load_svg): wrap macro definitions in parentheses. Bug: https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=45179 2022-02-23 Ben Wagner <bungeman@chromium.org> [psaux] Full bounds check for OtherSubr 19. It is possible for OtherSubr 19 to be invoked when `decoder->buildchar` is NULL (so that `decoder->len_buildchar` is 0), the `blend` is non-NULL with `blend->num_designs` set to 2, and the user supplied `idx` to be large (for example 0xFFFFFFFE). Since these are all `FT_UInt32` the existing bounds check overflows in a well defined manner, allowing for an invalid call to `memcpy`. In addition, it is possible to call OtherSubr 19 with `decoder->len_buildchar`, `blend->num_designs`, and `idx` all zero (implying that `blend->weight_vector` and `decoder->buildchar` are NULL). This passes the bounds check (it is logically always fine to copy nothing starting at index zero) but may invoke undefined behavior in `ft_memcpy` if it is backed by `memcpy`. Calling `memcpy` with either the `src` or `dst` NULL is undefined behavior (even if `count` is zero). * src/psaux/psintrp.c (cf2_interpT2CharString): Correctly check that `blend->num_designs` can be copied to `decoder->buildchar[idx]`. Also avoid passing NULL to `ft_memcpy`. Bug: https://crbug.com/1299259 2022-02-21 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> [cmake] Drop the support of CMake 2.x. * CMakeLists.txt: Require CMake 3.0 (released on 2014) or newer. The issue #1059 reports the difficulty to support both of CMake 2.x and newer one by single CMakeLists.txt without the inflation of cmake_policy() workarounds.

This reverts commit d276bcb7f0c02c20d3585b2e5626702df6d140a6. The original commit did avoid the use of uninitialized memory. However, it appears that the original commit is no longer required. The underlying issue was resolved by a change in freetype2-testing "Build bzip2 correctly." [0]. Prior to [0] bzip2 was built without msan, so bzip2 writes were not tracked or considered initialized. Clearing `buffer` in the original commit allowed msan to see the `buffer` content initialized once in FreeType code, but msan saw no writes into buffer from bzip2. With bzip2 now built with msan, the bzip2 writes are properly instrumented and msan sees the bzip2 writes into the buffer. As a result the original commit can be safely reverted to allow for better detection of other uninitialized data scenarios. * src/bzip2/ftbzip2.c (FT_Stream_OpenBzip2): Revert to using `FT_QNEW`. [0] https://github.com/freetype/freetype2-testing/commit/3c052a837a3c960709227a0d6ddd256e87b88853 2022-01-11 Ben Wagner <bungeman@chromium.org> [type42] Track how much type42 ttf data is available. Currently `T42_Open_Face` eagerly allocates 12 bytes for the ttf header data which it expects `t42_parse_sfnts` to fill out from /sfnts data. However, there is no guarantee that `t42_parse_sfnts` will actually be called while parsing the type42 data as the /sfnts array may be missing or very short. This is also confusing behavior as it means `T42_Open_Face` is tightly coupled to the implementation of the very distant `t42_parse_sfnts` code which requires at least 12 bytes to already be reserved in `face->ttf_data`. `t42_parse_sfnts` itself eagerly updates `face->ttf_size` to track how much space is reserved for ttf data instead of traking how much data has actually been written into `face->ttf_data`. It will also act strangely in the presense of multiple /sfnts arrays. * src/type42/t42objs.c (T42_Open_Face): ensure `ttf_data` is initialized to NULL. Free `ttf_data` on error. * src/type42/t42parse.c (t42_parse_sfnts): delay setting `ttf_size` and set it to the actual number of bytes read.

We now first apply zlib's `zlib2ansi` script, then FreeType's patch file. * src/gzip/README.freetype: Updated. * patches/0001-zlib-Fix-zlib-sources-to-compile-for-FreeType.patch: Renamed to... * patches/freetype-zlib.diff: This. Clean up description, then regenerate it as follows: - Copy unmodified files from `zlib` repository. - Run `zlib2ansi` script. - Run `git diff -R > patches/freetype-zlib.diff.new`. - Insert patch description of old diff file, then replace old diff with new diff file. 2022-01-09 David Turner <david@freetype.org> [gzip] Update sources to zlib 1.2.11 This can be tested by building with the Unix development build make setup devel make or by building the freetype-demos programs with meson setup build -Dfreetype2:zlib=internal meson compile -C out and trying to run `ftview` with a `.pcf.gz` font file. * src/gzip/ftgzip.c, src/gzip/rules.mk: Update for new zlib sources. Also remove the temporary fix introduced in commit 6a431038 to work around the fact that the internal sources were too old. * src/gzip/README.freetype: New file describing the origin of the sources and how they were modified. * src/gzip/patches/: Patch files applied to original sources. src/gzip/: Updated zlib sources with the patch file(s) from `src/gzip/patches/` applied, followed by a conversion with zlib's `zlib2ansi` script. 2022-01-09 David Turner <david@freetype.org> [meson] Change Zlib configuration option. meson_options.txt, meson.build: Change the format of the 'zlib' meson build configuration option to be a combo with the following choices: - none: Do not support gzip-compressed streams at all. - internal: Support gzip-compressed streams using the copy of the gzip sources under `src/gzip/`; this should only be used during development to ensure these work properly. - external: Support gzip-compressed streams using the 'zlib' Meson subproject, linked as a static library. - system: Support gzip-compressed streams using a system-installed version of zlib. - auto: Support gzip-compressed streams using a system-installed version of zlib, if available, or using the 'zlib' subproject otherwise. This is the default. - disabled: Backward-compatible alias for 'none'. - enabled: Backward-compatible alias for 'auto'. 2022-01-09 Werner Lemberg <wl@gnu.org> [bzip2] Avoid use of uninitialized memory. * src/bzip2/ftbzip2.c (FT_Stream_OpenBzip2): Don't use `FT_QNEW` but `FT_NEW` for setting up `zip` to avoid uninitialized memory access while handling malformed PCF fonts later on. Fixes https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=42800 2022-01-09 Alexei Podtelezhnikov <apodtele@gmail.com> [sfnt] Fix off-by-one error. The 0-base index is equal to the number of previosly parsed entries. It is an error to adjust it by one to get the number truncated by a stream error. This is probably inconsequential because valid entries are correctly accounted for. * src/sfnt/ttload.c (check_table_dir): Do not adjust the truncated number of tables. 2022-01-08 Werner Lemberg <wl@gnu.org> [sfnt, type42] Correct previous commit. Really fix https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=42773. * src/sfnt/ttload.c (check_table_dir): Revert change. * src/type42/t42.parse.c (t42_parse_sfnts): Don't use `FT_QREALLOC` but `FT_REALLOC` for setting up `ttf_data` to avoid uninitialized memory access while handling malformed TrueType fonts later on. 2022-01-07 Werner Lemberg <wl@gnu.org> * src/sfnt/ttload.c (check_table_dir): Initialize `table`. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=42773 2022-01-07 Werner Lemberg <wl@gnu.org> [sfnt] Avoid 'runtime error: applying zero offset to null pointer'. * src/sfnt/ttsbit.c (tt_sbit_decoder_load_byte_aligned): Exit early if `line` is NULL. 2022-01-07 Werner Lemberg <wl@gnu.org> [autofit, pshinter] Use `FT_OFFSET`. This avoids ``` runtime error: applying zero offset to null pointer ``` warnings of clang's undefined behaviour sanitizer. * src/autofit/afcjk.c (af_cjk_hints_link_segments, af_cjk_hints_compute_edges, af_cjk_hints_compute_blue_edges, af_cjk_hint_edges, af_cjk_align_edge_points): Do it. * src/autofit/afhints.c (af_glyph_hints_align_edge_points, af_glyph_hints_align_strong_points): Ditto. * src/autofit/aflatin.c (af_latin_metrics_init_widths, af_latin_hints_link_segments, af_latin_hints_compute_edges, af_latin_hints_compute_blue_edges, af_latin_hint_edges): Ditto. * src/pshinter/pshalgo.c (psh_hint_table_init): Ditto. 2022-01-06 Ben Wagner <bungeman@chromium.org> [truetype] Reset localpoints when varying cvt. When iterating over the cvt tuples and reading in the points it is necessary to set all of `localpoints`, `points`, and `point_count` in all cases. The existing code did not reset `localpoints` to `NULL` when there were no private point numbers. If the previous tuple did have private point numbers and set `localpoints` to `ALL_POINTS` this would not be cleared and the wrong branch would be taken later, leading to possible heap buffer overflow. * src/truetype/ttgxvar.c (tt_face_vary_cvt): Reset `localpoints` to `NULL` when it isn't valid. Fixes: https://crbug.com/1284742 2022-01-02 Werner Lemberg <wl@gnu.org> * builds/unix/configure.raw: Restore `SYSTEM_ZLIB` variable. This was accidentally removed with commit 93ebcbd0 almost eight years ago. 2021-12-27 Alexander Borsuk <me@alex.bio> Fix warnings for CMake Unity builds. * src/cache/ftcbasic.c (FT_COMPONENT): Undefine macro before redefinition. * src/smooth/ftgrays.c (TRUNC, FRACT): Ditto. 2021-12-18 Alexander Borsuk <alexander.borsuk@qnective.com> Clang-Tidy warning fixes. * src/base/ftobjs.c (FT_Get_Paint): Operator has equivalent nested operands. * src/bdf/bdflib.c (_bdf_add_property): Value stored to `fp` is never read. * src/sdf/ftbsdf.c (bsdf_init_distance_map): Value stored to `pixel` is never read. * src/sdf/ftsdf.c (split_sdf_shape): Value stored to `error` is never read. 2021-12-17 Eli Schwartz <eschwartz@archlinux.org> * meson.build: Optimize lookup for `python3` program. The python module's `find_installation` method is intended to provide routines for compiling and installing python modules into the `site-packages` directory. It does a couple of slow things, including run an introspection command to scrape sysconfig info from the detected interpreter, which are not needed for the sole use case of invoking the found installation as an executable. Furthermore, when invoked without the name or path of a python binary, it is hardcoded to always look for `python3` corresponding to the interpreter meson itself uses to run. So using `find_installation` did not even allow detecting `python2` as a fallback. Instead, switch to a simple `find_program` lookup that finishes as soon as the program is found. 2021-12-17 Eli Schwartz <eschwartz@archlinux.org> * builds/meson/.py: Fix name of python executable for auxiliary scripts. The previous change to check the return code of `run_command` invocations caused the CI to fail. Although most scripts used `python_exe` as the program command, the script to determine the project version did not. But, all scripts used `python` as the shebang, and this is not available on all systems. Particularly Debian does not provide a `python` command, though `python3` does exist. This meant that formerly the version number was lacking, and now the build simply fails. Instead, rely on `python3` since it is guaranteed to exist when running meson, and `python2` is end of life anyway. 2021-12-17 Eli Schwartz <eschwartz@archlinux.org> meson.build: Check the return value of `run_command`. By default, errors are not checked and a command that is somehow broken will just capture incorrect output (likely an empty string). Current development versions of meson now raise a warning for this implicit behavior, and advise explicitly setting the `check:` keyword argumend to determine whether a failing return code should be considered an error. Since none of the commands in this project are expected to fail, mark them as required to succeed. 2021-12-13 Alexei Podtelezhnikov <apodtele@gmail.com> [truetype] Upstream the hdmx binary search. * src/truetype/ttobjs.h (TT_SizeRec): Add `widthp` for the hdmx widths. * src/truetype/ttobjs.c (tt_size_reset): Initialize `widthp` even though it might never be used by the interpreter. * src/truetype/ttgload.c (tt_loader_init): Avoid repeated searches in the hdmx table. 2021-12-12 Alexei Podtelezhnikov <apodtele@gmail.com> [truetype] Reset the IUP-called flags for each subglyph. This fixes fall-out from 7809007a5b88b15, where the composite accents were no longer hinted. * src/truetype/ttgload.c (ttloader_init): Move the IUP-called flag initialization from here... * src/truetype/ttinterp.c (TT_Run_Context): ... to here. 2021-12-12 Alexei Podtelezhnikov <apodtele@gmail.com> [truetype] Binary search through the `hdmx` records. The `hdmx` table is supposed to be sorted by ppem size, which enables binary search. We also drop the check for the sufficient length of the record because it is now enforced when the table is loaded. * include/freetype/internal/tttypes.h (TT_FaceRec): Store the `hdmx` record pointers sorted by ppem instead of ppem's themselves. * src/truetype/ttpload.c (tt_face_load_hdmx): Prudently sort records. (tt_face_get_device_metrics): Implement binary search to retrieve advances. 2021-12-12 Alexei Podtelezhnikov <apodtele@gmail.com> [truetype] Honor FT_LOAD_ADVANCE_ONLY if `hdmx` is usable. This simply shortcuts the glyph loading if FT_LOAD_ADVANCE_ONLY is specified by FT_Get_Advances and the `hdmx` data are located. Particularly, the classic v35 interpreter or "verified" ClearType fonts might see 100x speed up in retrieving the hdmx cache. * src/truetype/ttgload.c (TT_Load_Glyph): Insert the shortcut. 2021-12-12 Alexei Podtelezhnikov <apodtele@gmail.com> [truetype] Initialize the loader with `hdmx` data. The `hdmx` matching can be done before the glyph is loaded. * include/freetype/internal/tttypes.h (TT_LoaderRec): Add a field. * src/truetype/ttgload.c (compute_glyph_metrics): Relocate the `hdmx` code from here... (tt_loader_init): ... to here, before the glyph is loaded. 2021-12-12 Alexei Podtelezhnikov <apodtele@gmail.com> [truetype] Relocate subpixel flag setting. `TT_RunIns` is too busy to deal with subpixel flags. It is better to set them in `tt_loader_init`, which is executed before each glyph program. * src/truetype/ttinterp.c (TT_RunIns): Move the flag setting from here... * src/truetype/ttgload.c (tt_loader_init): ... to here. 2021-12-12 Alexei Podtelezhnikov <apodtele@gmail.com> [truetype] Limit INSTCTRL appication within specs. * src/truetype/ttinterp.c (Ins_INSTCTRL): Limit its global effects to the CVT program and local effects to the glyph program. This also fixes an Infinality buglet. The `ignore_x_mode` should be locally unset by the glyph program. 2021-12-09 Ben Wagner <bungeman@chromium.org> [bdf] Fix use of uninitialized value. In _bdf_readstream if the data contained no newline then the buffer would continue to grow and uninitialized data read until either the uninitialized data contained a newline or the buffer reached its maxiumum size. The assumption was that the line was always too long and the buffer had been filled, however this case can also happen when there is not enough data to fill the buffer. Correct this by properly setting the cursor to the end of the available data, which may be different from the end of the buffer. This may still result in one extra allocation, but only on malformed fonts. * src/bdf/bdflib.c (_bfd_readstream): Correctly update cursor. Remove unread set of `avail`. Bug: https://lists.nongnu.org/archive/html/freetype-devel/2021-12/msg00001.html 2021-12-07 Alexei Podtelezhnikov <apodtele@gmail.com> [truetype] Reduce Infinality footprint again. * src/truetype/ttgload.c (compute_glyph_metrics): Streamline and prioritize the Infinality checks to use `hdmx`. 2021-12-07 Cameron Cawley <ccawley2011@gmail.com> [builds/windows] Guard some non-ancient API. We can support Windows 98 and NT 4.0 in principle... * builds/windows/ftdebug.c, builds/windows/ftsystem.c: Check for the ancient SDK using _WIN32_WINDOWS, _WIN32_WCE, or _WIN32_WINNT. 2021-12-07 Cameron Cawley <ccawley2011@gmail.com> * builds/windows/visualc/freetype.vcproj: Add missing file. 2021-12-02 Werner Lemberg <wl@gnu.org> * Version 2.11.1 released. ========================== Tag sources with `VER-2-11-1'. * docs/VERSION.TXT: Add entry for version 2.11.1. * docs/CHANGES, docs/release: Updated. * README, src/base/ftver.rc, builds/windows/vc2010/index.html, builds/windows/visualc/index.html, builds/windows/visualce/index.html, builds/wince/vc2005-ce/index.html, builds/wince/vc2008-ce/index.html, docs/freetype-config.1: s/2.11.0/2.11.1/, s/2110/2111/. * include/freetype/freetype.h (FREETYPE_PATCH): Set to 1. * builds/unix/configure.raw (version_info): Set to 24:1:18. * CMakeLists.txt (VERSION_PATCH): Set to 1. * builds/toplevel.mk (version_tag, CHANGELOG_SCRIPT): New variables. (do-dist): Generate `ChangeLog` file with all commits since last release. 2021-11-30 Alexei Podtelezhnikov <apodtele@gmail.com> [builds/windows] Improve debugging. * builds/windows/ftdebug.c (FT_Message, FT_Panic): Buffer output and call `OutputDebugStringA` only if `IsDebuggerPresent`. [_WIN32_WCE] (OutputDebugStringA): Implement the missing API. 2021-11-29 Seigo Nonaka <nona@google.com> * src/base/ftobjs.c (FT_Request_Metrics): Fix build warning on Android. Use casts since `FT_USHORT_MAX` is unsigned short in bionic (libc used in Android). 2021-11-28 Alexei Podtelezhnikov <apodtele@gmail.com> * builds/windows/vc2010/freetype.vcxproj (DlgCopy): Minor tweak. 2021-11-26 Alexei Podtelezhnikov <apodtele@gmail.com> * src/truetype/ttpload.c (tt_face_load_hdmx): Added comments. 2021-11-26 Alexei Podtelezhnikov <apodtele@gmail.com> [truetype] Quietly reject out-of-spec `hdmx` tables. The `hdmx` table is optional and can be safely rejected without an error if it does not follow specifications. The record size must be equal to the number of glyphs + 2 + 32-bit padding. * src/truetype/ttpload.c (tt_face_load_hdmx): Thoroughly check the record size and improve tracing. 2021-11-23 Alexei Podtelezhnikov <apodtele@gmail.com> [truetype] Partly revert 5b626281. Fixes #1118. * src/truetype/ttpload.c (tt_face_load_hdmx): Do not assume that `record_size` is rounded even though the records are padded. 2021-11-23 Alexei Podtelezhnikov <apodtele@gmail.com> * builds/windows/vc2010/freetype.vcxproj (DlgCopy): Use transforms. 2021-11-22 Werner Lemberg <wl@gnu.org> Update `CHANGES` files, other minor whitespace and documentation issues. 2021-11-21 Werner Lemberg <wl@gnu.org> formats.txt: Add info about WOFF and WOFF2. 2021-11-21 Werner Lemberg <wl@gnu.org> meson.build: Initialize `common_ldflags`. 2021-11-21 Lukas Oberhuber <@lukaso> * meson.build: Fix compatibility version on MacOS. Fixes #1117. 2021-11-21 Werner Lemberg <wl@gnu.org> * src/truetype/ttinterp.c (Ins_MD): Avoid `FT_ABS`. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=38562 2021-11-20 Alexei Podtelezhnikov <apodtele@gmail.com> * include/freetype/fttypes.h (FT_MAKE_TAG): Remove the same casting. 2021-11-20 Werner Lemberg <wl@gnu.org> [gxvalid] Fix minor compilation warning. * src/gxvalid/gxvmort5.c (gxv_mort_subtable_type5_subtable_setup): Declare as static. 2021-11-20 Werner Lemberg <wl@gnu.org> [smooth] Fix stand-alone compilation. * src/smooth/ftgrays.c (FT_Trace_Enable, FT_Trace_Disable)[STANDALONE_]: Define. 2021-11-20 Werner Lemberg <wl@gnu.org> Avoid undefined left-shifts.

(FT_STATIC_BYTE_CAST): ... this. 2021-11-18 Werner Lemberg <wl@gnu.org> Provide C++ versions for public macros with casts. Many FreeType clients use C++. However `g++ -Wold-style-cast` warns for macros with C-style casts even for system header files; this also affects directories included with `-isystem`. While this could be seen as a problem with g++, the problem is more a philosophical one: Over the time, C and C++ diverged more and more, and some features of C are no longer the 'right' solution in C++. * include/freetype/config/public-macros.h (FT_STATIC_CAST, FT_REINTERPRET_CAST): New macros. * include/freetype/freetype.h (FT_ENC_TAG, FT_LOAD_TARGET_, FT_LOAD_TARGET_MODE): Use `FT_STATIC_CAST`.

Recognize new format and reject it for now. 2021-11-16 Werner Lemberg <wl@gnu.org> [truetype] Updates for the forthcoming OpenType 1.9 standard (1/2). This is in preparation for implementing `DeltaSetIndexMap` format 1, which is used by `COLR` v1 tables, and which allows 32bit indices. https://docs.microsoft.com/en-us/typography/opentype/otspec190/delta/otvarcommonformats_delta.html * src/truetype/ttgxvar.h (GX_DeltaSetIdxMapRec): Change type of `mapCount` to `FT_ULong`. * src/truetype/ttgxvar.c (ft_var_load_delta_set_index_mapping): Add argument for passing the table size; update caller.

The current code will error if any of these are present and invalid, but will not error and will provide uninitialized data if the Blend dictionary exists but does not contain one of these entries. This change reverts to the older behavior of treating any missing entries as containing all zero data and not returning an error. In the future it may be best to keep track of when these are actually initialized and error if they are not. * src/type1/t1load.c (t1_allocate_blend): Zero initiailize. 2021-10-26 Alexei Podtelezhnikov <apodtele@gmail.com> [builds/windows] Add MSVC linker optimazations.

Previously the `blend->weight_vector`, `blend->default_weight_vector`, and `blend->design_pos` were set early to allocated but uninitialized memory under the assumption that the memory would eventually be initialized. However, it is possible that some of the required keywords may not actually be present, leaving the memory uninitialized. This is different from a present but invalid table, which would produce an error. Reported as https://bugs.chromium.org/p/chromium/issues/detail?id=1261762 * src/type1/t1load.c (t1_allocate_blend): Remove early allocation and initialization. (parse_blend_design_positions, parse_weight_vector): Parse into local and assign to blend if valid. (T1_Open_Face): Check that if a blend exists that it has the weight vector and design positions. 2021-10-21 Ben Wagner <bungeman@chromium.org> [cff] Commit vstore data and regions on allocation. The vstore->regionCount and vstore->dataCount were read directly from the data. However, vstore->varRegionList and vstore->varData would still contain uninitialized entries with uninitialized pointers in the event of an error, leading to issues when attempting to clean up. Reportd as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=40104 * src/cff/cffload.c (cff_vstore_load): Read the region and data counts into locals and update the vstore counts immediately after each entry becomes free-able. 2021-10-20 Ben Wagner <bungeman@chromium.org> [sfnt] Delay setting gasp ranges and count until computed. Previously, the gasp.numRanges was set and gasp.gaspRanges was allocated and assigned before a possible early exit if the frame could not be entered. It is also possible that the gaspRanges allocation could fail but the numRanges still be set to non-zero. In such cases an error would be returned, but the face would have a gasp in an inconsistent state which may still be accessed. Reported as https://bugs.chromium.org/p/chromium/issues/detail?id=1261450 * src/sfnt/ttload.c (tt_face_load_gasp): Delay setting gasp.numRanges and gasp.gaspRanges until after the ranges are initialized. 2021-10-20 Ben Wagner <bungeman@chromium.org> [sfnt] Delay setting names and langTags until computed. Previously, the table->names and table->langTags fields were created pointing to uninitialized memory and an early exit could happen if the frame could not be entered. The caller would then be unable to properly dispose of the memory as the string fields had not been initialized. Reported as https://bugs.chromium.org/p/chromium/issues/detail?id=1261343 * src/sfnt/ttload.c (tt_face_load_name): delay setting table->langTags and table->names until after the memory they will point to is fully initialized. 2021-10-20 Alexei Podtelezhnikov <apodtele@gmail.com> * tests/issue-1063/main.c: s/PATH_MAX/FILENAME_MAX/.

These two are not equal when FreeType is used as a subproject, such as in `freetype-demos`. In that case, `source_root` points at the root project, causing the docs build to fail. 2021-10-05 Alexei Podtelezhnikov <apodtele@gmail.com> * src/smooth/ftgrays.c (FT_DIV_MOD): Limit the ARM workaround. 2021-10-05 Alexei Podtelezhnikov <apodtele@gmail.com> [builds/unix, builds/vms] Standardize `mmap` failure. * builds/unix/ftsystem.c (FT_Stream_Open): Check for MAP_FAILED. * builds/vms/ftsystem.c (FT_Stream_Open): Ditto. This should cover https://savannah.nongnu.org/patch/?5909 as well. 2021-10-05 Hugh McMaster <hugh.mcmaster@outlook.com> autogen.sh: Only copy submodules if building from a git branch. `autogen.sh` fails if building from a standard source tarball. Firstly, git expects to be called in a git repository, then `copy_submodule_files` blindly attempts to copy files. Debian, Ubuntu, Linux Mint, and other derivatives all run `autogen.sh` before compiling to regenerate build files. This patch ensures that various git commands are only called and 'dlg' files are only copied if `autogen.sh` is called from a git repository. 2021-10-05 Alexei Podtelezhnikov <apodtele@gmail.com> * include/freetype/internal/ftgloadr.h: Add missing header.

With PIXEL_BITS = 8, this corresponds to 65,000 pixels or the bitmap size that we refuse to render anyway.

(ADD_INT) [STANDALONE_]: New macro. (FT_INTEGRATE): Use ADD_INT. 2021-08-07 Dominik Röttsches <drott@chromium.org> [sfnt] Add API for retrieving a 'COLR' v1 'ClipBox' table. The optional 'COLR' v1 glyph-specific clip box helps upstream graphics libraries allocate a sufficiently large bitmap for a glyph without having to traverse the glyph graph for that. See https://github.com/googlefonts/colr-gradients-spec/issues/251 for background on the introduction of this specification change. * include/freetype/ftcolor.h (FT_ClipBox): New structure. (FT_Get_Color_Glyph_ClipBox): New function declaration. * include/freetype/internal/sfnt.h (TT_Get_Color_Glyph_ClipBox_Func): New function type.

(gray_render_conic) [BEZIER_USE_DDA]: Use it. 2021-08-02 Werner Lemberg <wl@gnu.org> * meson.build: Fix zlib support. This commit synchronizes zlib support with both autotools and cmake: If no external zlib is found (or intentionally disabled on the command line), use the internal zlib by undefining `FT_CONFIG_OPTION_SYSTEM_ZLIB` without modifying `FT_CONFIG_OPTION_USE_ZLIB`. Also improve summary output. Problem reported by Moazin. 2021-08-02 Anuj Verma <anujv@iitbhilai.ac.in> [sdf] Fix out-of-range-access. * src/sdf/ftbsdf.c (first_pass, second_pass): Fix range during forward pass. Otherwise the index goes out of range for the last column. Fixes issue #1077. 2021-08-02 Anuj Verma <anujv@iitbhilai.ac.in> Fix invalid memory access in `bsdf` rasterizer. Do not generate SDF from bitmap if the `FT_GLYPH_OWN_BITMAP` flag is not set. In some cases the bitmap buffer is freed but still points to a valid address; to handle those cases check the flag before accessing the memory. * src/sdf/ftsdfrend.c (ft_bsdf_render): Handle the above case. Also, return an error message if the bitmap's rows/pitch is invalid, otherwise `slot->buffer` might be assigned to some invalid memory location. (ft_sdf_render): Same as above. Plus, move the outline back to original state after rasterization and not if any error occurs. 2021-07-29 Heiko Becker <heirecka@exherbo.org> * meson.build: Honor `--includedir` instead of hard-coding 'include'. 2021-07-29 Werner Lemberg <wl@gnu.org> src/sfnt/ttcolr.c: Minor formatting. 2021-07-29 Dominik Röttsches <drott@chromium.org> [sfnt] 'COLR' v1 PaintSweepGradient spec update * src/sfnt/ttcolr.c (read_paint): PaintSweepGradient follows other spec changes and now has the angles specified as F2DOT14, reflect that in the implementation. * include/freetype/ftcolor.h (FT_PaintSweepGradient): Update documentation. 2021-07-29 Dominik Röttsches <drott@chromium.org> [sfnt] Retrieve affine matrix from offset in 'COLR' v1 parsing. * src/sfnt/ttcolr.c (read_paint): Implement spec change where affine transform matrix is now referenced by offset instead of being placed inline in the PaintTransform table. 2021-07-29 Dominik Röttsches <drott@chromium.org> [sfnt] 'COLR' v1 PaintSkew related spec updates * src/sfnt/ttcolr.c (read_paint): Implement spec changes around PaintSkew, PaintSkewAroundCenter. Update parsing to read shorter values as changed in the spec. * include/freetype/ftcolor.h (FT_PaintSkew): Update documentation. 2021-07-29 Dominik Röttsches <drott@chromium.org> [sfnt] PaintRotate/PaintRotateAroundCenter spec updates * src/sfnt/ttcolr.c (read_paint): Implement spec change where PaintRotate and PaintRotateAroundCenter were split for a more compact format definition. Update parsing to read shorter values as changed in the spec. * include/freetype/ftcolor.h (FT_PaintRotate): Update documentation. 2021-07-29 Dominik Röttsches <drott@chromium.org> [sfnt] 'COLR' v1 PaintTranslate and PaintScale precision * src/sfnt/ttcolr.c (read_paint): Implement spec changes in PaintTranslate and PaintScale and friends. Update parsing to read new shorter values. 2021-07-29 AnuthaDev <anuthadev@gmail.com> README.git: Add Code of Conduct. 2021-07-25 Werner Lemberg <wl@gnu.org> ChangeLog housekeeping. Archive old `ChangeLog` file. We no longer write ChangeLog entries manually; instead, the file will be created from commit messages (which should be formatted in GNU's ChangeLog style) by a call to gitlog-to-changelog --format='%B%n' or something similar (this script is part of the 'gnulib' repository). 2021-07-24 Werner Lemberg <wl@gnu.org> Fix some `cppcheck` warnings. * src/bzip2/ftbzip2.c (ft_bzip2_file_skip_output), src/gzip/ftgzip.c (ft_gzip_file_skip_output): Reduce scope of `delta`. * src/psaux/psintrp.c, src/psaux/psintrp.h (cf2_interpT2CharString): Add `const` to `buf` parameter. * src/raster/ftraster.c (DelOld): Add `const` to `profile` parameter. (Vertical_Sweep_Span): Reduce scope of `target`. (FT_Outline_Get_CBox): Reduce scope of `xMin`, `xMax`, `yMin`, `yMax`. * src/smooth/ftgrays.c (gray_render_conic): Reduce scope of `split`. (gray_sweep, gray_sweep_direct): Reduce scope of `area`. * src/tools/apinames.c (names_dump) <OUTPUT_WATCOM_LBC>: Reduce scope of `temp`. 2021-07-24 AnuthaDev <anuthadev@gmail.com> * .gitlab-ci.yml: Fixed cmake build, using correct options. 2021-07-24 AnuthaDev <anuthadev@gmail.com> * CMakeLists.txt: Make `cmake` handle disabled dependencies correctly. Include 'CMakeDependentOption'. Replace `FT_WITH_XXX` options with `FT_DISABLE_XXX` and `FT_REQUIRE_XXX` pairs. Update option logic accordingly. Fixes #1066. 2021-07-24 Ben Wagner <bungeman@chromium.org> [autofit] Split `afwrtsys.h`. The header file `afwrtsys.h` has two distinct functions: to include the required writing system headers and also to generate code for each writing system. At each current use site only one or the other is used, with various macro trickery selecting one or the other. Split this header into `afws-decl.h` for the required writing system declarations and `afws-iter.h` for iterating over the writing systems to generate code. The motivation for this change is that the Visual C++ compiler treats the standard include guard idiom like `#pragma once` 'if no non-comment code or preprocessor directive comes before or after the standard form of the idiom'. It appears to check this after macro expansion, so if `WRITING_SYSTEM` expands to empty the bottom of `afwrtsys.h` is empty and looks like the standard include guard idiom which is treated like `#pragma once`, so subsequent inclusion of `afwrtsys.h` is elided. Fixes #1075. * src/autofit/afglobal.c (af_writing_system_classes), src/autofit/aftypes.h (AF_WritingSystem), src/autofit/rules.mk (AUTOF_DRV_H): Updated. * src/autofit/afwrtsys.h: Split into... * src/autofit/afws-decl.h, src/autofit/afws-iter.h: New files.	whupdup/frame	real/third_party/freetype-2.12.0/ChangeLog	none	gpl-3.0	100,764

FreeType 2.12.0 =============== Homepage: https://www.freetype.org FreeType is a freely available software library to render fonts. It is written in C, designed to be small, efficient, highly customizable, and portable while capable of producing high-quality output (glyph images) of most vector and bitmap font formats. Please read the `docs/CHANGES` file, it contains IMPORTANT INFORMATION. Read the files `docs/INSTALL*` for installation instructions; see the file `docs/LICENSE.TXT` for the available licenses. For using FreeType's git repository instead of a distribution bundle, please read file `README.git`. The FreeType 2 API reference is located in directory `docs/reference`; use the file `index.html` as the top entry point. [Please note that currently the search function for locally installed documentation doesn't work due to cross-site scripting issues.] Additional documentation is available as a separate package from our sites. Go to https://download.savannah.gnu.org/releases/freetype/ and download one of the following files. freetype-doc-2.12.0.tar.xz freetype-doc-2.12.0.tar.gz ftdoc2120.zip To view the documentation online, go to https://www.freetype.org/freetype2/docs/ Mailing Lists ------------- The preferred way of communication with the FreeType team is using e-mail lists. general use and discussion: freetype@nongnu.org engine internals, porting, etc.: freetype-devel@nongnu.org announcements: freetype-announce@nongnu.org git repository tracker: freetype-commit@nongnu.org The lists are moderated; see https://www.freetype.org/contact.html how to subscribe.

README.git ========== repository issues ----------------- FreeType's official repository site is https://gitlab.freedesktop.org/freetype , from which the 'freetype.git' and 'freetype-demos.git' repositories can be cloned in the usual way. git clone https://gitlab.freedesktop.org/freetype/freetype.git git clone https://gitlab.freedesktop.org/freetype/freetype-demos.git If you want to use the Savannah mirror instead, you have to do a slightly different incantation because the repository names contain digit '2' for historical reasons. git clone \ https://git.savannah.nongnu.org/git/freetype/freetype2.git \ freetype git clone \ https://git.savannah.nongnu.org/git/freetype/freetype2-demos.git \ freetype-demos standard builds with `configure` -------------------------------- The git repository doesn't contain pre-built configuration scripts for UNIXish platforms. To generate them say sh autogen.sh which in turn depends on the following packages: automake (1.10.1) libtool (2.2.4) autoconf (2.62) The versions given in parentheses are known to work. Newer versions should work too, of course. Note that `autogen.sh` also sets up proper file permissions for the `configure` and auxiliary scripts. The `autogen.sh` script checks whether the versions of the above three tools match the numbers above. Otherwise it will complain and suggest either upgrading or using environment variables to point to more recent versions of the required tools. Note that `aclocal` is provided by the 'automake' package on Linux, and that `libtoolize` is called `glibtoolize` on Darwin (OS X). alternative build methods ------------------------- For static builds that don't use platform-specific optimizations, no configure script is necessary at all; saying make setup ansi make should work on all platforms that have GNU `make` (or `makepp`). A build with `cmake` or `meson` can be done directly from the git repository. However, if you want to use the `FT_DEBUG_LOGGING` macro (see file `docs/DEBUG` for more information) it is currently mandatory to execute `autogen.sh` in advance; this script clones the 'dlg' git submodule and copies some files into FreeType's source tree.

There are three ways to use * this file to build project-specific versions of the library: * * - You can modify this file by hand, but this is not recommended in * cases where you would like to build several versions of the library * from a single source directory. * * - You can put a copy of this file in your build directory, more * precisely in `$BUILD/freetype/config/ftoption.h`, where `$BUILD` is * the name of a directory that is included _before_ the FreeType include * path during compilation. * * The default FreeType Makefiles use the build directory * `builds/<system>` by default, but you can easily change that for your * own projects. * * - Copy the file <ft2build.h> to `$BUILD/ft2build.h` and modify it * slightly to pre-define the macro `FT_CONFIG_OPTIONS_H` used to locate * this file during the build. For example, * * ``` * #define FT_CONFIG_OPTIONS_H <myftoptions.h> * #include <freetype/config/ftheader.h> * ``` * * will use `$BUILD/myftoptions.h` instead of this file for macro * definitions. * * Note also that you can similarly pre-define the macro * `FT_CONFIG_MODULES_H` used to locate the file listing of the modules * that are statically linked to the library at compile time.

CHANGES BETWEEN 2.11.1 and 2.12.0 I. IMPORTANT CHANGES - FreeType now handles OT-SVG fonts, to be controlled with `FT_CONFIG_OPTION_SVG` configuration macro. By default, it can only load the 'SVG ' table of an OpenType font. However, by using the `svg-hooks` property of the new 'ot-svg' module it is possible to register an external SVG rendering engine. The FreeType demo programs have been set up to use 'librsvg' as the rendering library. This work was Moazin Khatti's GSoC 2019 project. II. MISCELLANEOUS - The handling of fonts with an 'sbix' table has been improved. - Corrected bitmap offsets. - A new tag `FT_PARAM_TAG_IGNORE_SBIX` for `FT_Open_Face` makes FreeType ignore an 'sbix' table in a font, allowing applications to access the font's outline glyphs. - `FT_FACE_FLAG_SBIX` and `FT_FACE_FLAG_SBIX_OVERLAY` together with their corresponding preprocessor macros `FT_HAS_SBIX` and `FT_HAS_SBIX_OVERLAY` enable applications to treat 'sbix' tables as described in the OpenType specification. - The internal 'zlib' code has been updated to be in sync with the current 'zlib' version (1.2.11). - The previously internal load flag `FT_LOAD_SBITS_ONLY` is now public. - Some minor improvements of the building systems, in particular handling of the 'zlib' library (internal vs. external). - Support for non-desktop Universal Windows Platform. - Various other minor bug and documentation fixes. - The `ftdump` demo program shows more information for Type1 fonts if option `-n` is given. - `ftgrid` can now display embedded bitmap strikes. ====================================================================== CHANGES BETWEEN 2.11.0 and 2.11.1 I. IMPORTANT CHANGES - Some fields in the `CID_FaceDictRec`, `CID_FaceInfoRec`, and `FT_Data` structures have been changed from signed to unsigned type, which better reflects the actual usage. It is also an additional means to protect against malformed input. II. MISCELLANEOUS - Cmake support has been further improved. To do that various backward-incompatible changes were necessary; please see file `CMakeLists.txt` for more details. - Since version 2.11.0, a C99 compiler is necessary to compile FreeType. - The experimental 'COLR' v1 API has been updated to the latest OpenType standard 1.9. - The `apinames` tool got a new option `-wV` to output an OpenVMS Linker Option File. - VMS support was updated. - MS Visual Studio support was added to build the demo programs. ====================================================================== CHANGES BETWEEN 2.10.4 and 2.11.0 I. IMPORTANT CHANGES - A new rendering module has been added to create 8-bit Signed Distance Field (SDF) bitmaps for both outline and bitmap glyphs. The new rendering mode is called `FT_RENDER_MODE_SDF`, the pixel mode is `FT_PIXEL_MODE_GRAY8`, and the corresponding raster flag is `FT_RASTER_FLAG_SDF`. This work was Anuj Verma's GSoC 2020 project. - A new, experimental API is now available for surfacing properties of 'COLR' v1 color fonts (as the name says, this is an extension to the 'COLR' table for outline color fonts using the SFNT container format). 'COLR' v1 fonts are a recently proposed addition to OFF and OpenType; specification work currently happens in https://github.com/googlefonts/colr-gradients-spec/ 'COLR' v1 is expected to be merged to OpenType; the ISO standardisation process for adding 'COLR' v1 as an amendment to OFF is underway. Functions similar to the already existing 'COLR' API have been added to access the corresponding data. FT_Get_Color_Glyph_Paint Retrieve the root paint for a given glyph ID. FT_Get_Paint_Layers Access the layers of a `PaintColrLayers` table. FT_Get_Colorline_Stops Retrieve the 'color stops' on a color line. As an input, a color stop iterator gets used, which in turn is retrieved from a paint. FT_Get_Paint Dereference an `FT_OpaquePaint` object and retrieve the corresponding `FT_COLR_Paint` object, which contains details on how to draw the respective 'COLR' v1 `Paint` table. II. MISCELLANEOUS - FreeType has moved its infrastructure to https://gitlab.freedesktop.org/freetype A side effect is that the git repositories are now called `freetype.git` and `freetype-demos.git`, which by default expand to the directories `freetype` and `freetype-demos`, respectively. The documentation has been updated accordingly. FreeType's Savannah repositories will stay; they are now mirrors of the 'freedesktop.org' repositories. - A new function `FT_Get_Transform` returns the values set by `FT_Set_Transform`. - A new configuration macro `FT_DEBUG_LOGGING` is available. It provides extended debugging capabilities for FreeType, for example showing a time stamp or displaying the component a tracing message comes from. See file `docs/DEBUG` for more information. This work was Priyesh Kumar's GSoC 2020 project. - The legacy Type 1 and CFF engines are further demoted due to lack of CFF2 charstring support. You now need to use `FT_Property_Set` to enable them besides the `T1_CONFIG_OPTION_OLD_ENGINE` and `CFF_CONFIG_OPTION_OLD_ENGINE` options, respectively. - The experimental 'warp' mode (AF_CONFIG_OPTION_USE_WARPER) for the auto-hinter has been removed. - The smooth rasterizer performance has been improved by >10%. Note that due to necessary code changes there might be very subtle differences in rendering. They are not visible by the eye, however. - PCF bitmap fonts compressed with LZW (these are usually files with the extension `.pcf.Z`) are now handled correctly. - Improved Meson build files, including support to build the FreeType demo programs. - A new demo program `ftsdf` is available to display Signed Distance Fields of glyphs. - The `ftlint` demo program has been extended to do more testing of its input. In particular, it can display horizontal and vertical acutances for quality assessment, together with computing MD5 checksums of rendered glyphs. [The acutance measures how sharply the pixel coverage changes at glyph edges. For monochrome bitmaps, it is always 2.0 in either X or Y direction. For anti-aliased bitmaps, it depends on the hinting and the shape of a glyph and might approach or even reach value 2.0 for glyphs like 'I', 'L', '+', '-', or '=', while it might be lower for glyphs like 'O', 'S', or 'W'.] - The `ttdebug` demo program didn't show changed point coordinates (bug introduced in version 2.10.3). - It is now possible to adjust the axis increment for variable fonts in the `ftmulti` demo program. - It is now possible to change the hinting engine in the `ftstring` demo program. - The graphical demo programs work better now in native color depth on win32 and x11. ====================================================================== CHANGES BETWEEN 2.10.3 and 2.10.4 (2020-Oct-20) I. IMPORTANT BUG FIXES - A heap buffer overflow has been found in the handling of embedded PNG bitmaps, introduced in FreeType version 2.6. https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2020-15999 If you use option FT_CONFIG_OPTION_USE_PNG you should upgrade immediately. ====================================================================== CHANGES BETWEEN 2.10.2 and 2.10.3 (2020-Oct-10) I. IMPORTANT CHANGES - New flag `FT_OUTLINE_OVERLAP'. If set, make the smooth rasterizer do 4x4 oversampling to mitigate artifacts in pixels partially covered by overlapping contours. Note that this at least quadruples the rendering time. If a glyph in a TrueType font has the `OVERLAP_SIMPLE' or `OVERLAP_COMPOUND' bit set, FreeType automatically selects this rendering mode. II. MISCELLANEOUS - Using the arcane method of including FreeType header files with macros like `FT_FREETYPE_H' is no longer mandatory (but retained as an optional feature for backward compatibility). - Support for building the library with Meson. Building the demo programs with Meson will follow in a forthcoming release. - Minor improvements to the B/W rasterizer. - Auto-hinter support for Medefaidrin script. - Fix various memory leaks (mainly for CFF) and other issues that might cause crashes in rare circumstances. - Jam support has been removed. - In `ftview', custom LCD filter values are now normalized and balanced. Unorthodox filters are still available through the `-L' command line option. - The GUI demo programs can now be resized. - Demo programs that accept command line option `-k' can now handle function keys, too. The corresponding character codes start with 0xF1. As an example, the POSIX shell syntax (accepted by bash, ksh, and zsh) -k $'\xF3q' emulates the pressing of function key `F3' followed by key `q'. ====================================================================== CHANGES BETWEEN 2.10.1 and 2.10.2 (2020-May-09) I. IMPORTANT CHANGES - Support of WOFF2 fonts. This code contribution was Nikhil Ramakrishnan's GSoC 2019 project. II. MISCELLANEOUS - Function `FT_Get_Var_Axis_Flags' returned random data for Type 1 MM fonts. - Type 1 fonts with non-integer metrics are now supported by the new (CFF) engine introduced in FreeType 2.9. - Drop support for Python 2 in Freetype's API reference generator `docwriter' (Python >= 3.5 is required for targets `make refdoc' and `make refdoc-venv'). - Auto-hinter support for Hanifi Rohingya. - Document the `FT2_KEEP_ALIVE' debugging environment variable. - The Visual C++ (and Visual C) project files for Windows builds no longer generate libraries that contain the FreeType version in its filenames. Instead, a resource file gets used to make the libraries contain the corresponding information. - The next release will remove Jam build support. - The `ftbench' demo program has a new test for testing the `FT_Glyph_Stroke' functionality. ====================================================================== CHANGES BETWEEN 2.10.0 and 2.10.1 (2019-Jul-01) I. IMPORTANT BUG FIXES - The bytecode hinting of OpenType variation fonts was flawed, since the data in the `CVAR' table wasn't correctly applied. II. MISCELLANEOUS - Auto-hinter support for Mongolian. - For distribution, `.tar.bz2' packages are replaced with `.tar.xz' bundles. - The handling of the default character in PCF fonts as introduced in version 2.10.0 was partially broken, causing premature abortion of charmap iteration for many fonts. - If `FT_Set_Named_Instance' was called with the same arguments twice in a row, the function returned an incorrect error code the second time. - Direct rendering using FT_RASTER_FLAG_DIRECT crashed (bug introduced in version 2.10.0). - Increased precision while computing OpenType font variation instances. - The flattening algorithm of cubic Bezier curves was slightly changed to make it faster. This can cause very subtle rendering changes, which aren't noticeable by the eye, however. - The auto-hinter now disables hinting if there are blue zones defined for a `style' (i.e., a certain combination of a script and its related typographic features) but the font doesn't contain any characters needed to set up at least one blue zone. - The `ftmulti' demo program now supports multiple hidden axes with the same name tag. - `ftview', `ftstring', and `ftgrid' got a `-k' command line option to emulate a sequence of keystrokes at start-up. - `ftview', `ftstring', and `ftgrid' now support screen dumping to a PNG file. - The bytecode debugger, `ttdebug', now supports variation TrueType fonts; a variation font instance can be selected with the new `-d' command line option. ====================================================================== CHANGES BETWEEN 2.9.1 and 2.10.0 (2019-Mar-15) I. IMPORTANT CHANGES - A bunch of new functions has been added to access and process COLR/CPAL data of OpenType fonts with color-layered glyphs. FT_Palette_Data_Get Retrieve color palette data. FT_Palette_Select Select and activate a color palette for color-layered glyphs. FT_Palette_Set_Foreground_Color Set text foreground color for palette index 0xFFFF. FT_Get_Color_Glyph_Layer Get color layers for a given glyph (using an interator object). FT_Bitmap_Blend Blend one bitmap onto another with a given color. - An experimental feature is the new behaviour of the `FT_LOAD_COLOR' load flag for color-layered glyphs: Internally it sets a flag so that if `FT_Render_Glyph' is called with `FT_RENDER_MODE_NORMAL' (or `FT_Load_Glyph' with `FT_LOAD_RENDER'), a default blending of the color glyph layers will happen automatically for convenience. - As a GSoC 2018 project, Nikhil Ramakrishnan completely overhauled and modernized the API reference. II. MISCELLANEOUS - The logic for computing the global ascender, descender, and height of OpenType fonts has been slightly adjusted for consistency. . If the `useTypoMetrics' flag (i.e., bit 7 in the `fsSelection' field) in the `OS/2' table is set, use the `sTypo' fields in `OS/2' unconditionally. . Otherwise use the metrics data from the `hhea' table (if not zero). . Otherwise use the `sTypo' fields from the `OS/2' table (if not zero). . Otherwise use the `usWin' data from the `OS/2' table as a last resort. Variable fonts will apply the `MVAR' deltas to whichever metrics were picked. - `TT_Set_MM_Blend' could fail if call repeatedly with the same arguments. - The precision of handling deltas in Variation Fonts has been increased. The problem did only show up with multidimensional designspaces. - New function `FT_Library_SetLcdGeometry' to set up the geometry of LCD subpixels. - FreeType now uses the `defaultChar' property of PCF fonts to set the glyph for the undefined character at glyph index 0 (as FreeType already does for all other supported font formats). As a consequence, the order of glyphs of a PCF font if accessed with FreeType can be different now compared to previous versions. This change doesn't affect PCF font access with cmaps. - `FT_Select_Charmap' has been changed to allow parameter value `FT_ENCODING_NONE', which is valid for BDF, PCF, and Windows FNT formats to access built-in cmaps that don't have a predefined `FT_Encoding' value. - A previously reserved field in the `FT_GlyphSlotRec' structure now holds the glyph index. - On Win32 platforms, the use of `_DLL' to build the library has been replaced with `DLL_EXPORT' and `DLL_IMPORT'. - The usual round of fuzzer bug fixes to better reject malformed fonts. - `FT_Outline_New_Internal' and `FT_Outline_Done_Internal' have been removed. These two functions were public by oversight only and were never documented. - A new function `FT_Error_String' returns descriptions of error codes if configuration macro FT_CONFIG_OPTION_ERROR_STRINGS is defined. - `FT_Set_MM_WeightVector' and `FT_Get_MM_WeightVector' are new functions limited to Adobe MultiMaster fonts to directly set and get the weight vector. - Support for Position Independent Code as needed by systems that prohibit automatic address fixups, such as BREW, has been removed. [Compilation with modern compilers that use flags like `-fPIC' or `-fPIE' is not affected.] - The `ftdump' demo program has new options `-c' and `-C' to display charmaps in compact and detailed format, respectively. Option `-V' has been removed. - The `ftview', `ftstring', and `ftgrid' demo programs use a new command line option `-d' to specify the program window's width, height, and color depth. - The `ftview' demo program now displays red boxes for zero-width glyphs. - `ftglyph' has limited support to display fonts with color-layered glyphs. This will be improved later on. - `ftgrid' can now display bitmap fonts also. - The `ttdebug' demo program has a new option `-f' to select a member of a TrueType collection (TTC). - Other various improvements to the demo programs. ====================================================================== CHANGES BETWEEN 2.9 and 2.9.1 (2019-May-01) I. IMPORTANT BUG FIXES - Type 1 fonts containing flex features were not rendered correctly (bug introduced in version 2.9). - CVE-2018-6942: Older FreeType versions can crash with certain malformed variation fonts. https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2018-6942 II. MISCELLANEOUS - Bug fix: Multiple calls to `FT_Get_MM_Var' returned garbage. - The base extensions `ftlcdfil' and `ftfntfmt' are now part of the base module (and thus no longer configurable in file `modules.cfg'). - Emboldening of bitmaps didn't work correctly sometimes, showing various artifacts (bug introduced in version 2.8.1). - Use of the `freetype-config' script to get compilation and linking options is deprecated since it doesn't support cross-compiling, among other deficiencies. Instead, you should use the `pkg-config' interface. The `configure' script no longer installs `freetype-config' by default. For backward compatibility, a new configure option `--enable-freetype-config' is provided that reverts this decision. - The auto-hinter script ranges have been updated for Unicode 11. No support for new scripts have been added, however, with the exception of Georgian Mtavruli. - Support for cmake has been improved. - The next release will remove support for Position Independent Code as needed by systems that prohibit automatic address fixups, such as BREW. [Compilation with modern compilers that use flags like `-fPIC' or `-fPIE' is not affected.] ====================================================================== CHANGES BETWEEN 2.8.1 and 2.9 (2018-Jan-08) I. IMPORTANT BUG FIXES - Advance width values of variation fonts were often wrong. - More fixes for variation font support; you should update to this version if you want to support them. II. IMPORTANT CHANGES - As a GSoC project, Ewald Hew extended the new (Adobe) CFF engine to handle Type 1 fonts also, thus greatly improving the rendering of this format. This is the new default. The old engine is still available if the configuration macro `T1_CONFIG_OPTION_OLD_ENGINE' gets defined; using the `hinting-engine' property of the `type1' driver module you can then switch between the two engines. - A new function, `FT_Set_Named_Instance', can be used to set or change the current named instance. - Starting with this FreeType version, resetting variation coordinates will return to the currently selected named instance. Previously, FreeType returned to the base font (i.e., no instance set). III. MISCELLANEOUS - The `face_flags' field of the `FT_Face' structure has a new bit, `FT_FACE_FLAG_VARIATION', which is set if a variation font has been altered with `FT_Set_MM_Design_Coordinates', `FT_Set_Var_Design_Coordinates', or `FT_Set_Var_Blend_Coordinates'. - If the current face is a named instance, the new macro `FT_IS_NAMED_INSTANCE' returns true. - `FT_IS_VARIATION' is a new macro that returns true whenever a face object has been altered by `FT_Set_MM_Design_Coordinates', `FT_Set_Var_Design_Coordinates', or `FT_Set_Var_Blend_Coordinates'. - Changing the design coordinates of a variation font with `FT_Set_Var_Design_Coordinates' or `FT_Set_Var_Blend_Coordinates' does not influence the named instance index value (only `FT_Set_Named_Instance' does that). - Special PostScript names for named instances are only returned if the named instance is set with `FT_Set_Named_Instance' (and the font has corresponding entries in its `fvar' table). If `FT_IS_VARIATION' returns true, the algorithmically derived PostScript name is provided, not looking up special entries for named instances. - A new function `FT_Done_MM_Var' is provided to free the memory returned in a call to `FT_Get_MM_Var'. - On platforms using the `configure' script, the installed `ftoption.h' file now correctly reflects configuration options like `--with-harfbuzz'. - Better support to build FreeType as a DLL on Windows using Visual C. - All data specific to driver modules is now collected in a single file, `FT_DRIVER_H'. Consequently, the macros `FT_AUTOHINTER_H', `FT_CFF_DRIVER_H', `FT_TRUETYPE_DRIVER_H', and `FT_PCF_DRIVER_H' still work but are deprecated. - Some fuzzer fixes to better reject malformed fonts. - The `ftbench' demo program has a new test for opening a new face and loading some glyphs. - The `ftbench' demo program has a new option `-j' to specify the last glyph index to be used in the tests. - The `ftgrid' demo program has a new option `-n' to suppress display of named instances of variation fonts. - The `ttdebug' demo program can now show a stack trace (key `K') and switch between hexadecimal and decimal display of integers (key `I'). ====================================================================== CHANGES BETWEEN 2.8 and 2.8.1 (2017-Sep-16) I. IMPORTANT BUG FIXES - B/W hinting of TrueType fonts didn't work properly if interpreter version 38 or 40 was selected. - Some severe problems within the handling of TrueType Variation Fonts were found and fixed. - Function `FT_Set_Var_Design_Coordinates' didn't correctly handle the case with less input coordinates than axes. II. IMPORTANT CHANGES - By default, FreeType now offers high quality LCD-optimized output without resorting to ClearType techniques of resolution tripling and filtering. In this method, called Harmony, each color channel is generated separately after shifting the glyph outline, capitalizing on the fact that the color grids on LCD panels are shifted by a third of a pixel. This output is indistinguishable from ClearType with a light 3-tap filter. III. MISCELLANEOUS - Using the new function `FT_Get_Var_Axis_Flags', an application can access the `flags' field of a variation axis (introduced in OpenType version 1.8.2) - More sanity checks. - The internal representation of buffers for LCD rendering has changed (to be more precise, the amount of padding gets computed differently). Applications that use the FreeType API are not affected. - To reset all design axis values of a variation font to its default values you can now say error = FT_Set_Var_Design_Coordinates( face, 0, NULL ); This also works with functions `FT_Set_MM_Design_Coordinates' and `FT_Set_MM_Blend_Coordinates'. - FreeType now synthesizes a missing Unicode cmap for (older) TrueType fonts also if glyph names are available. - FreeType has improved handling of BDF fonts without the `POINT_SIZE', `RESOLUTION_X', or `RESOLUTION_Y' properties; the library now uses the values of the `SIZE' keyword if they are missing. Previously, `SIZE' was completely ignored, and FreeType used heuristic values instead. - Multiple calls to `FT_Bitmap_Convert' do work now as advertised. Previously, they failed with an assertion error if there was an empty bitmap between non-empty ones. - The warping option has moved from `light' to `normal' hinting where it replaces the original hinting algorithm. The `light' mode is now always void of any hinting in x-direction. - 16bit compiler support is now officially ended. We didn't provide any maintenance since many years, and given that there were no error or problem reports either it seems that it is no longer needed. - The `ftgrid' demo program can now toggle the display of grid lines with the `G' key. - The `ftgrid' demo program can toggle a different set of colors (suitable to color-blind people) with the `C' key. - The `ftgrid' demo program now supports the `-e' command line option to select a cmap. - The `ftdump' demo program has a new command line option `-t' to output the SFNT table list. ====================================================================== CHANGES BETWEEN 2.7.1 and 2.8 (2017-May-13) I. IMPORTANT CHANGES - Support for OpenType Variation Fonts is now complete. The last missing part was handling the `VVAR' and `MVAR' tables, which is available with this release. - A new function `FT_Face_Properties' allows the control of some module and library properties per font. Currently, the following properties can be handled: stem darkening, LCD filter weights, and the random seed for the `random' CFF operator. - The PCF change to show more `colorful' family names (introduced in version 2.7.1) was too radical; it can now be configured with PCF_CONFIG_OPTION_LONG_FAMILY_NAMES at compile time. If activated, it can be switched off at run time with the new pcf property `no-long-family-names'. If the `FREETYPE_PROPERTIES' environment variable is available, you can say FREETYPE_PROPERTIES=pcf:no-long-family-names=1 - Support for the following scripts has been added to the auto-hinter. Adlam, Avestan, Bamum, Buhid, Carian, Chakma, Coptic, Cypriot, Deseret, Glagolitic, Gothic, Kayah, Lisu, N'Ko, Ol Chiki, Old Turkic, Osage, Osmanya, Saurashtra, Shavian, Sundanese, Tai Viet, Tifinagh, Unified Canadian Syllabics, Vai II. IMPORTANT BUG FIXES - `Light' auto-hinting mode no longer uses TrueType metrics for TrueType fonts. This bug was introduced in version 2.4.6, causing horizontal scaling also. Almost all GNU/Linux distributions (with Fedora as a notable exception) disabled the corresponding patch for good reasons; chances are thus high that you won't notice a difference. If optical backward compatibility for legacy applications is necessary, you might enable the AF_CONFIG_OPTION_TT_SIZE_METRICS configuration option. However, it is strongly recommended to avoid that, adjusting font sizes instead. - Global size metrics values in the `FT_Size_Metrics' structure can be different for TrueType fonts. Reason is that in older FreeType versions the metrics were rounded differently to integer pixels compared to all other font formats, yielding an inconsistent behaviour if you used non-native hinting. Starting with this version, global size metrics for TrueType fonts are handled the same as other font formats: `ascender' gets rounded up, `descender' gets rounded down, `height' gets normally rounded, and `max_advance' gets normally rounded, too. If you need more precise values of (global) ascender, descender, height, or `max_advance', please take the corresponding values from the `FT_Face' structure and scale them manually. - If a TrueType font gets loaded with FT_LOAD_NO_HINTING, FreeType now scales the font linearly again (bug introduced in version 2.4.6). - CVE-2017-8105, CVE-2017-8287: Older FreeType versions have out-of-bounds writes caused by heap-based buffer overflows related to Type 1 fonts. https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2017-8105 https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2017-8287 III. MISCELLANEOUS - A new function `FT_Set_Default_Properties' has been added to parse the `FREETYPE_PROPERTIES' environment variable (previously, it was internal only). `FT_Init_FreeType' always call this function, but `FT_New_Library' does not (similar to `FT_Add_Default_Modules'). - To be in sync with OpenType version 1.7 and newer, macros FT_PARAM_TAG_IGNORE_PREFERRED_FAMILY, FT_PARAM_TAG_IGNORE_PREFERRED_SUBFAMILY, TT_NAME_ID_PREFERRED_FAMILY TT_NAME_ID_PREFERRED_SUBFAMILY are renamed to FT_PARAM_TAG_IGNORE_TYPOGRAPHIC_FAMILY, FT_PARAM_TAG_IGNORE_TYPOGRAPHIC_SUBFAMILY, TT_NAME_ID_TYPOGRAPHIC_FAMILY TT_NAME_ID_TYPOGRAPHIC_SUBFAMILY The old macro names are deprecated (but still available). - Support for SFNT `name' tables has been improved. . Format 1 `name' tables are now supported. Use new function `FT_Get_Sfnt_LangTag' to access associated language tags. . Language, encoding, and name IDs have been updated to OpenType version 1.8.1. - The new CFF engine now handles the `random' operator. All CFF opcodes are now supported. - The CFF module has a new property `random-seed' to control the pseudo-random number generation for the `random' operator. - The `freetype-config' script is now a wrapper of `pkg-config' if this program is available in the path. - FT_LOAD_TARGET_LCD is now a variant of FT_LOAD_TARGET_LIGHT; this should provide better rendering results. - A mode to display light auto-hinting with subpixel positioning has been added to `ftdiff'. ====================================================================== CHANGES BETWEEN 2.7 and 2.7.1 (2016-Dec-30) I. IMPORTANT CHANGES - Support for the new CFF2 font format as introduced with OpenType 1.8 has been contributed by Dave Arnolds from Adobe. - Preliminary support for variation fonts as specified in OpenType 1.8 (in addition to the already existing support for Adobe's MM and Apple's GX formats). Dave Arnolds contributed handling of advance width change variation; more will come in the next version. II. IMPORTANT BUG FIXES - Handling of raw CID fonts was partially broken (bug introduced in 2.6.4). - CVE-2016-10328: Older FreeType versions had an out-of-bounds write caused by a heap-based buffer overflow related to the CFF fonts. https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2016-10328 III. MISCELLANEOUS - Some limits for TrueType bytecode execution have been tightened to speed up FreeType's handling of malformed fonts, in particular to quickly abort endless loops. - The number of twilight points can no longer be set to an arbitrarily large value. - The total number of jump opcode instructions (like JMPR) with negative arguments is dynamically restricted; the same holds for the total number of iterations in LOOPCALL opcodes. The dynamic limits are based on the number of points in a glyph and the number of CVT entries. Please report if you encounter a font where the selected values are not adequate. - PCF family names are made more `colorful'; they now include the foundry and information whether they contain wide characters. For example, you no longer get `Fixed' but rather `Sony Fixed' or `Misc Fixed Wide'. - A new function `FT_Get_Var_Blend_Coordinates' (with its alias name `FT_Get_MM_Blend_Coordinates') to retrieve the normalized blend coordinates of the currently selected variation instance has been added to the Multiple Masters interface. - A new function `FT_Get_Var_Design_Coordinates' to retrieve the design coordinates of the currently selected variation instance has been added to the Multiple Masters interface. - A new load flag `FT_LOAD_BITMAP_METRICS_ONLY' to retrieve bitmap information without loading the (embedded) bitmap itself. - Retrieving advance widths from bitmap strikes (using `FT_Get_Advance' and `FT_Get_Advances') have been sped up. - The usual round of fuzzer fixes to better reject malformed fonts. - The `ftmulti' demo program can now switch engines with key `H'. - The `ftstring' demo program can now show some built-in, non-latin sample strings (to be selected with the TAB key). - The `ftview' demo program can now switch between a font's charmaps using the TAB key. ====================================================================== CHANGES BETWEEN 2.6.5 and 2.7 (2016-Sep-08) I. IMPORTANT CHANGES - As announced earlier, the 2.7.x series now uses the new subpixel hinting mode as the default, emulating a modern version of ClearType. This change inevitably leads to different rendering results, and you might change the `TT_CONFIG_OPTION_SUBPIXEL_HINTING' configuration option to adapt it to your taste (or use the new `FREETYPE_PROPERTIES' environment variable). See the corresponding entry below for version 2.6.4, which gives more information. - A new option `FT_CONFIG_OPTION_ENVIRONMENT_PROPERTIES' has been introduced. If set (which is the default), an environment variable `FREETYPE_PROPERTIES' can be used to control driver properties. Example: FREETYPE_PROPERTIES=truetype:interpreter-version=35 \ cff:no-stem-darkening=1 \ autofitter:warping=1 This allows to select, say, the subpixel hinting mode at runtime for a given application. See file `ftoption.h' for more. II. IMPORTANT BUG FIXES - After loading a named instance of a GX variation font, the `face_index' value in the returned `FT_Face' structure now correctly holds the named instance index in the upper 16bits as documented. III. MISCELLANEOUS - A new macro `FT_IS_NAMED_INSTANCE' to test whether a given face is a named instance. - More fixes to GX font handling. - Apple's `GETVARIATION' bytecode operator (needed for GX variation font support) has been implemented. - Another round of fuzzer fixes, mainly to reject invalid fonts faster. - Handling of raw CID fonts was broken (bug introduced in version 2.6.4). - The smooth rasterizer has been streamlined to make it faster by approx. 20%. - The `ftgrid' demo program now understands command line option `-d' to give start-up design coordinates. - The `ftdump' demo program has a new command line option `-p' to dump TrueType bytecode instructions. ====================================================================== CHANGES BETWEEN 2.6.4 and 2.6.5 (2016-Jul-12) I. IMPORTANT BUG FIXES - Compilation works again on Mac OS X (bug introduced in version 2.6.4). II. IMPORTANT CHANGES - The new subpixel hinting mode is now disabled by default; it will be enabled by default in the forthcoming 2.7.x series. Main reason for reverting this feature is the principle of least surprise: a sudden change in appearance of all fonts (even if the rendering improves for almost all recent fonts) should not be expected in a new micro version of a series. ====================================================================== CHANGES BETWEEN 2.6.3 and 2.6.4 (2016-Jul-05) I. IMPORTANT CHANGES - A new subpixel hinting mode has been contributed by Nikolaus Waxweiler, which is now the default rendering mode for TrueType fonts. It implements (almost everything of) version 40 of the bytecode engine. The existing code base in FreeType (the `Infinality code') was stripped to the bare minimum and all configurability removed in the name of speed and simplicity. The configurability was mainly aimed at legacy fonts like Arial, Times New Roman, or Courier. [Legacy fonts are fonts that modify vertical stems to achieve clean black-and-white bitmaps.] The new mode focuses on applying a minimal set of rules to all fonts indiscriminately so that modern and web fonts render well while legacy fonts render okay. Activation of the subpixel hinting support can be controlled with the `TT_CONFIG_OPTION_SUBPIXEL_HINTING' configuration option at compile time: If set to value 1, you get the old Infinality mode (which was never the default due to its slowness). Value 2 activates the new subpixel hinting mode, and value 3 activates both. The default is value 2. At run time, you can select the subpixel hinting mode with the `interpreter-version' property (provided you have compiled in the corresponding hinting mode); see `ftttdrv.h' for more. - Support for the following scripts has been added to the auto-hinter. Armenian, Cherokee, Ethiopic, Georgian, Gujarati, Gurmukhi, Malayalam, Sinhala, Tamil II. MISCELLANEOUS - Type 42 fonts as created by LilyPond are now supported. - Minor rendering improvements in the auto-hinter. - For experimental reasons, the old CFF engine now supports all CFF operators except `random', including the deprecated Multiple Masters instructions. This allows the display of fonts like `ITCGaramondMM-It.otf' (without font variations, though). - Another round of fixes to improve handling of invalid fonts. - The `ftgrid' demo program now displays the rendered pixels also; this can be switched off with the `b' key. Selection of various LCD filtering modes can be done with the `L' key. - The demo programs have been extended to allow selection of all available TrueType bytecode engines. - A very early beta version of a new, Qt based demo program called `ftinspect' is part of the source code bundle; it will eventually supersede the other demo programs. Currently, you have to compile it manually with `qmake; make'; note that many features are still missing. ====================================================================== CHANGES BETWEEN 2.6.2 and 2.6.3 (2016-Feb-08) I. IMPORTANT CHANGES - Khmer, Myanmar, Bengali, and Kannada script support has been added to the auto-hinter. II. MISCELLANEOUS - Better support of Indic scripts like Devanagari by using a top-to-bottom hinting flow. - All FreeType macros starting with two underscores have been renamed to avoid a violation of both the C and C++ standards. Example: Header macros of the form `__FOO_H__' are now called `FOO_H_'. In most cases, this should be completely transparent to the user. The exception to this is `__FTERRORS_H__', which must be sometimes undefined by the user to get FreeType error strings: Both this form and the new `FTERRORS_H_' macro are accepted for backward compatibility. - Minor improvements mainly to the Type 1 driver. - The new CFF engine now supports all Type 2 operators except `random'. - The macro `_STANDALONE_', used for compiling the B/W and smooth rasterizers as stand-alone modules, has been renamed to `STANDALONE_', since macro names starting with an underscore and followed by an uppercase letter are reserved in both C and C++. - Function `FT_Library_SetLcdFilterWeights' now also activates custom LCD filter weights (instead of just adjusting them). - Support for `unpatented hinting' has been completely removed: Consequently, the two functions `FT_Face_CheckTrueTypePatents' and `FT_Face_SetUnpatentedHinting' now return always false, doing nothing. - The `ftgamma' demo program has been modernized; the gamma grid display has been moved from `ftview' to this program. - In `ftview', it is now possible to cycle through the available LCD filtering modes. ====================================================================== CHANGES BETWEEN 2.6.1 and 2.6.2 (2015-Nov-28) I. IMPORTANT CHANGES - The auto-hinter now supports stem darkening, to be controlled by the new `no-stem-darkening' and `darkening-parameters' properties. This is an experimental feature contributed by Nikolaus Waxweiler, and the interface might change in a future release. - By default, stem darkening is now switched off (for both the CFF engine and the auto-hinter). The main reason is that you need linear alpha blending and gamma correction to get correct rendering results, and the latter is not yet available in most freely available rendering stacks like X11. Applying stem darkening without proper gamma correction leads to far too dark rendering results. - The meaning of `FT_RENDER_MODE_LIGHT' has been slightly modified. It now essentially means `no hinting along the horizontal axis'; in particular, no change of glyph advance widths. Consequently, the auto-hinter is used for all scalable font formats except for CFF. It is planned that other font-specific rendering engines (TrueType, Type 1) will follow. II. MISCELLANEOUS - The default LCD filter has been changed to be normalized and color-balanced. - For better compatibility with FontConfig, function `FT_Library_SetLcdFilter' accepts a new enumeration value `FT_LCD_FILTER_LEGACY1' (which has the same meaning as `FT_LCD_FILTER_LEGACY'). - A large number of bugs have been detected by using the libFuzzer framework, which should further improve handling of invalid fonts. Thanks again to Kostya Serebryany and Bungeman! - `TT_CONFIG_OPTION_MAX_RUNNABLE_OPCODES', a new configuration option, controls the maximum number of executed opcodes within a bytecode program. You don't want to change this except for very special situations (e.g., making a library fuzzer spend less time to handle broken fonts). - The smooth renderer has been made faster. - The `ftstring' demo program now supports subpixel rendering; use key `l' to cycle through the LCD modes. - The `ftstring' demo program now supports color rendering; use the `space' key to cycle through various color combinations. - The graphical demo programs now use a default gamma value of 1.8 (instead of 1.2). ====================================================================== CHANGES BETWEEN 2.6 and 2.6.1 (2015-Oct-04) I. IMPORTANT BUG FIXES - It turned out that for CFFs only the advance widths should be taken from the `htmx' table, not the side bearings. This bug, introduced in version 2.6.0, makes it necessary to upgrade if you are using CFFs; otherwise, you get cropped glyphs with GUI interfaces like GTK or Qt. - Accessing Type 42 fonts returned incorrect results if the glyph order of the embedded TrueType font differs from the glyph order of the Type 42 charstrings table. II. IMPORTANT CHANGES - The header file layout has been changed (again), moving all header files except `ft2build.h' into a subdirectory tree. Doing so reduces the possibility of header file name clashes (e.g., FTGL's `FTGlyph.h' with FreeType's `ftglyph.h') on case insensitive file systems like Mac OS X or Windows. Applications that use (a) the `freetype-config' script or FreeType's `freetype2.pc' file for pkg-config to get the include directory for the compiler, and (b) the documented way for header inclusion like #include <ft2build.h> #include FT_FREETYPE_H ... don't need any change to the source code. - Simple access to named instances in GX variation fonts is now available (in addition to the previous method via FreeType's MM interface). In the `FT_Face' structure, bits 16-30 of the `face_index' field hold the current named instance index for the given face index, and bits 16-30 of `style_flags' contain the number of instances for the given face index. `FT_Open_Face' and friends also understand the extended bits of the face index parameter. You need to enable TT_CONFIG_OPTION_GX_VAR_SUPPORT for this new feature. Otherwise, bits 16-30 of the two fields are zero (or are ignored). - Lao script support has been added to the auto-hinter. III. MISCELLANEOUS - The auto-hinter's Arabic script support has been enhanced. - Superscript-like and subscript-like glyphs as used by various phonetic alphabets like the IPA are now better supported by the auto-hinter. - The TrueType bytecode interpreter now runs slightly faster. - Improved support for builds with cmake. - The function `FT_CeilFix' now always rounds towards plus infinity. - The function `FT_FloorFix' now always rounds towards minus infinity. - A new load flag `FT_LOAD_COMPUTE_METRICS' has been added; it makes FreeType ignore pre-computed metrics, as needed by font validating or font editing programs. Right now, only the TrueType module supports it to ignore data from the `hdmx' table. - Another round of bug fixes to better handle broken fonts, found by Kostya Serebryany <kcc@google.com>. ====================================================================== CHANGES BETWEEN 2.5.5 and 2.6 (2015-Jun-07) I. IMPORTANT CHANGES - Behdad Esfahbod contributed code for improved thread-safety, which results in the following model. * An `FT_Face' object can only be safely used from one thread at a time. * An `FT_Library' object can now be used without modification from multiple threads at the same time. * `FT_Face' creation and destruction with the same `FT_Library' object can only be done from one thread at a time. One can use a single `FT_Library' object across threads as long as a mutex lock is used around `FT_New_Face' and `FT_Done_Face'. Any calls to `FT_Load_Glyph' and similar API are safe and do not need the lock to be held as long as the same `FT_Face' is not used from multiple threads at the same time. - Thai script support has been added to the auto-hinter. - Arabic script support has been added to the auto-hinter. - Following OpenType version 1.7, advance widths and side bearing values in CFFs (wrapped in an SFNT structure) are now always taken from the `hmtx' table. - Following OpenType version 1.7, the PostScript font name of a CFF font (wrapped in an SFNT structure) is now always taken from the `name' table. This is also true for OpenType Collections (i.e., TTCs using CFFs subfonts instead of TTFs), where it may have a significant difference. - Fonts natively hinted for ClearType are now supported, properly handling selector index 3 of the INSTCTRL bytecode instruction. - Major improvements to the GX TrueType variation font handling. II. MISCELLANEOUS - A new auto-hinter property `warping' can switch on and off the warping code if this experimental feature is compiled in (by defining the AF_CONFIG_OPTION_USE_WARPER configuration option; by default this option is now enabled but warping is switched off). The AF_CONFIG_OPTION_USE_WARPER option itself is an old feature, available since 2006. Warping only works in `light' auto-hinting mode. The idea of the code is to slightly scale and shift a glyph along the non-hinted dimension (which is usually the horizontal axis) so that as much of its segments are aligned (more or less) to the grid. To find out a glyph's optimal scaling and shifting value, various parameter combinations are tried and scored. See file `ftautoh.h' for more; the demo programs `ftdiff', `ftview', and `ftgrid' can toggle warping with key `w'. - Some fields in the `FTC_ImageTypeRec' structure have been changed from signed to unsigned type, which better reflects the actual usage. It is also an additional means to protect against malformed input. This change doesn't break the ABI; however, it might cause compiler warnings. - Function `FT_Bitmap_New' has been renamed to `FT_Bitmap_Init', since this name better reflects its function. For backward compatibility, the old function name is still available. - Function `FT_Get_X11_Font_Format' has been renamed to `FT_Get_Font_Format', since this name better reflects its function. For backward compatibility, the old function name is still available. Additionally, the header file macro for this function has been renamed to `FT_FONT_FORMATS_H' (the old name `FT_XFREE86_H' is retained for backward compatibility). - Various improvements to the `ftgrid' demo program. . It can now display GX and MM fonts while interactively manipulating the axes (with keys F2, F3, and F4). . Anti-aliasing rendering modes can now be selected (with keys F5 and F6). . The display of point numbers can be toggled with key `D'. - Various improvements to the `ftdump' demo program. . It now displays information on MM and GX variation axes. . New command line option `-u' makes it output data in utf-8 encoding. - The `ftmulti' demo program can now handle up to six MM or GX axes. ====================================================================== CHANGES BETWEEN 2.5.4 and 2.5.5 (2014-Dec-30) I. IMPORTANT BUG FIXES - Handling of uncompressed PCF files works again (bug introduced in version 2.5.4). ====================================================================== CHANGES BETWEEN 2.5.3 and 2.5.4 (2014-Dec-06) I. IMPORTANT BUG FIXES - A variant of vulnerability CVE-2014-2240 was identified (cf. https://savannah.nongnu.org/bugs/?43661) and fixed in the new CFF driver. All users should upgrade. - The new auto-hinter code using HarfBuzz crashed for some invalid fonts. - Many fixes to better protect against malformed input. II. IMPORTANT CHANGES - Full auto-hinter support of the Devanagari script. - Experimental auto-hinter support of the Telugu script. - CFF stem darkening behaviour can now be controlled at build time using the eight macros CFF_CONFIG_OPTION_DARKENING_PARAMETER_{X,Y}{1,2,3,4} . - Some fields in the `FT_Bitmap' structure have been changed from signed to unsigned type, which better reflects the actual usage. It is also an additional means to protect against malformed input. This change doesn't break the ABI; however, it might cause compiler warnings. III. MISCELLANEOUS - Improvements to the auto-hinter's algorithm to recognize stems and local extrema. - Function `FT_Get_SubGlyph_Info' always returned an error even in case of success. - Version 2.5.1 introduced major bugs in the cjk part of the auto-hinter, which are now fixed. - The `FT_Sfnt_Tag' enumeration values have been changed to uppercase, e.g. `FT_SFNT_HEAD'. The lowercase variants are deprecated. This is for orthogonality with all other enumeration (and enumeration-like) values in FreeType. - `cmake' now supports builds of FreeType as an OS X framework and for iOS. - Improved project files for vc2010, introducing a property file. - The documentation generator for the API reference has been updated to produce better HTML code (with proper CSS). At the same time, the documentation got a better structure. - The FT_LOAD_BITMAP_CROP flag is obsolete; it is not used by any driver. - The TrueType DELTAP[123] bytecode instructions now work in subpixel hinting mode as described in the ClearType whitepaper (i.e., for touched points in the non-subpixel direction). - Many small improvements to the internal arithmetic routines. ====================================================================== CHANGES BETWEEN 2.5.2 and 2.5.3 (2014-Mar-06) I. IMPORTANT BUG FIXES - A vulnerability (CVE-2014-2240) was identified and fixed in the new CFF driver (cf. https://savannah.nongnu.org/bugs/?41697). All users should upgrade. - More bug fixes related to correct positioning of composite glyphs. - Many fixes to better protect against malformed input. II. IMPORTANT CHANGES - FreeType can now use the HarfBuzz library to greatly improve the auto-hinting of fonts that use OpenType features: Many glyphs that are part of such features but don't have cmap entries are now handled properly, for example small caps or superscripts. Define the configuration macro FT_CONFIG_OPTION_USE_HARFBUZZ to activate HarfBuzz support. You need HarfBuzz version 0.9.19 or newer. Note that HarfBuzz depends on FreeType; this currently causes a chicken-and-egg problem that can be solved as follows in case HarfBuzz is not yet installed on your system. 1. Compile and install FreeType without the configuration macro FT_CONFIG_OPTION_USE_HARFBUZZ. 2. Compile and install HarfBuzz. 3. Define macro FT_CONFIG_OPTION_USE_HARFBUZZ, then compile and install FreeType again. With FreeType's `configure' script the procedure boils down to configure, build, and install FreeType, then configure, compile, and install HarfBuzz, then configure, compile, and install FreeType again (after executing `make distclean'). - All libraries FreeType depends on are now checked using the `pkg-config' configuration files first, followed by alternative methods. - The new value `auto' for the various `--with-XXX' library options (for example `--with-harfbuzz=auto') makes the `configure' script automatically link to the libraries it finds. This is now the default. - In case FreeType's `configure' script can't find a library, you can pass environment variables to circumvent pkg-config, and those variables have been harmonized as a consequence of the changes mentioned above: LIBZ -> removed; use LIBZ_CFLAGS and LIBZ_LIBS LIBBZ2 -> removed; use BZIP2_CFLAGS and BZIP2_LIBS LIBPNG_LDFLAGS -> LIBPNG_LIBS `./configure --help' shows all available environment variables. - The `freetype-config' script now understands option `--static' to emit static linking information. ====================================================================== CHANGES BETWEEN 2.5.1 and 2.5.2 (2013-Dec-08) I. IMPORTANT BUG FIXES - Improving the display of some broken TrueType fonts introduced a bug that made FreeType crash on some popular (but not fully conformant) fonts like `ahronbd.ttf'. - Another round of improvements to correct positioning and hinting of composite glyphs in TrueType fonts. II. MISCELLANEOUS - Version 2.5.1 introduced a bug in handling embedded bitmap strikes of TrueType fonts, causing garbage display under some circumstances. - The `ftgrid' demo program couldn't be compiled in non-development builds. ====================================================================== CHANGES BETWEEN 2.5 and 2.5.1 (2013-Nov-25) I. IMPORTANT BUG FIXES - For some WinFNT files, the last glyph wasn't displayed but incorrectly marked as invalid. - The vertical size of glyphs was incorrectly set after a call to `FT_GlyphSlot_Embolden', resulting in clipped glyphs. - Many fields of the `PCLT' table in SFNT based fonts (if accessed with `FT_Get_Sfnt_Table') were computed incorrectly. - In TrueType fonts, hinting of composite glyphs could sometimes deliver incorrect positions of components or even distorted shapes. II. IMPORTANT CHANGES - WOFF font format support has been added. - The auto-hinter now supports Hebrew. Greek and Cyrillic support has been improved. - Support for the forthcoming `OS/2' SFNT table version 5, as can be found e.g. in the `Sitka' font family for Windows 8.1. - The header file layout has been changed. After installation, all files are now located in `<prefix>/include/freetype2'. Applications that use (a) `freetype-config' or FreeType's `pkg-config' file to get the include directory for the compiler, and (b) the documented way for header inclusion like #include <ft2build.h> #include FT_FREETYPE_H ... don't need any change to the source code. III. MISCELLANEOUS - The stem darkening feature of the new CFF engine can now be fine-tuned with the new `darkening-parameters' property. - `ftgrid' has been updated to toggle various engines with the `H' key, similar to `ftview' and `ftdiff'. - The functionality of `ttdebug' has been greatly enhanced. . It now displays twilight, storage, and control value data; key `T' shows the twilight point table, key `S' the storage data, and key `C' the control value table. . Some keys have been reassigned from lowercase to their uppercase equivalents; for example `q' to quit the program is now `Q'. . Key `f' finishes the current function. . Key `R' restarts the debugger. . Keys `b' and `p' set a breakpoint. . Key `B' provides a function call backtrace. - Better support of ARMv7 and x86_64 processors. - Apple's `sbix' color bitmap format is now supported. - Improved auto-hinter rendering for many TrueType fonts, especially in the range 20-40ppem. - A new face flag `FT_FACE_FLAG_COLOR' has been added (to be accessed with the macro `FT_HAS_COLOR'). - `FT_Gzip_Uncompress' (modeled after zlib's `uncompress' function) has been added; this is a by-product of the newly added WOFF support. - Support for a build with `cmake' has been contributed by John Cary <cary@txcorp.com>. - Support for x64 builds with Visual C++ has been contributed by Kenneth Miller <kennethadammiller@yahoo.com> - Manual pages for most demo programs have been added. - The GETINFO bytecode instruction for TrueType fonts was buggy if used to retrieve subpixel hinting information. It was necessary to set selector bit 6 to get results for selector bits 7-10, which is wrong. - Improved computation of emulated vertical metrics for TrueType fonts. - Fixed horizontal start-up position of vertical phantom points in TrueType bytecode. ====================================================================== CHANGES BETWEEN 2.4.12 and 2.5 (2013-Jun-19) I. IMPORTANT BUG FIXES - The cache manager function `FTC_Manager_Reset' didn't flush the cache. II. IMPORTANT CHANGES - Behdad Esfahbod (on behalf of Google) contributed support for color embedded bitmaps (eg. color emoji). A new load flag, FT_LOAD_COLOR, makes FreeType load color embedded-bitmaps, following this draft specification https://color-emoji.googlecode.com/git/specification/v1.html which defines two new SFNT tables, `CBDT' and `CBLC' (named and modeled after `EBDT' and `EBLC', respectively). The color bitmaps are stored in the new FT_PIXEL_MODE_BGRA format to represent BGRA pre-multiplied sRGB images. If PNG support is available, PNG color images as defined in the same proposed specification are supported also. Note that color bitmaps are converted to grayscale if client didn't ask for color. - As announced in the previous release, the old FreeType CFF engine is now disabled by default. It can be conditionally compiled by defining the configuration macro CFF_CONFIG_OPTION_OLD_ENGINE. - As announced in the previous release, all code related to macro FT_CONFIG_OPTION_OLD_INTERNALS has been removed, thus becoming obsolete. III. MISCELLANEOUS - The property API (`FT_Property_Get' and `FT_Property_Set') is now declared as stable. The exception, however, are the experimental auto-hinter properties `glyph-to-script-map' and `fallback-script' which are subject to change in a forthcoming release. - `ftview' has been updated to support color embedded bitmaps; it can be toggled on and off with key `c'. The small cache toggle is now key `K'. - It is now possible to control the version of the TrueType hinting engine using the new `interpreter-version' property of the `truetype' module: Versions 35 and 38 (the default) are supported, which roughly corresponds to disable and enable subpixel hinting support, respectively. In both `ftview' and `ftdiff', switching between the two versions can be done with key `H'. In the `ftbench' demo program, command line option `-H' has been extended to activate the non-default interpreter version. - The `ttdebug' program has been further improved. In particular, it accepts a new command line option `-H' to select the hinting engine. - `ftdump's verbose option has been renamed to `-V'. For all demo programs, `-v' now shows version information. - Another round of TrueType subpixel hinting fixes. - The `apinames' tool can now create an import file for NetWare. - 64bit compilation of the new CFF engine was buggy. - Some fixes to improve robustness in memory-tight situations. ====================================================================== CHANGES BETWEEN 2.4.11 and 2.4.12 (2013-May-08) - We have another CFF parsing and hinting engine! Written by Dave Arnold <darnold@adobe.com>, this work has been contributed by Adobe in collaboration with Google. It is vastly superior to the old CFF engine, and it will replace it in the next release. Right now, it is still off by default, and you have to explicitly select it using the new `hinting-engine' property of the cff driver: ... #include FT_MODULE_H #include FT_CFF_DRIVER_H FT_Library library; int engine = FT_CFF_HINTING_ADOBE; ... FT_Property_Set( library, "cff", "hinting-engine", &engine ); The code has a (mature) beta status; we encourage all users to test it and report any problems. In case you want to activate the new CFF engine unconditionally, apply this patch: --- snip --- diff --git a/src/cff/cffobjs.c b/src/cff/cffobjs.c index ebcf189..3f2ce6b 100644 --- a/src/cff/cffobjs.c +++ b/src/cff/cffobjs.c @@ -1056,7 +1056,7 @@ /* set default property values / - driver->hinting_engine = FT_CFF_HINTING_FREETYPE; + driver->hinting_engine = FT_CFF_HINTING_ADOBE; driver->no_stem_darkening = FALSE; return FT_Err_Ok; --- snip --- - The macro FT_CONFIG_OPTION_OLD_INTERNALS is no longer set by default. In the next release, we will completely remove the associated code. Please update your programs in case you are still using this macro. II. MISCELLANEOUS - The (top-level) `configure' script now respects the MAKE environment variable to specify a `make' binary. For backward compatibility, GNUMAKE still overrides MAKE, though. - The `ftview' and `ftdiff' demo programs have been redesigned, showing more options permanently on the screen, among other minor improvements. - Using the `H' key, it is now possible to select the CFF engine in both `ftview' and `ftdiff'. - The new command line option `-H' for `ftbench' selects the Adobe CFF engine. - It is now possible to directly select the LCD rendering mode with the keys `A'-`F' in `ftview'. The key mapping for cycling through LCD modes has been changed from `K' and `L' to `k' and `l', and toggling custom LCD filtering is no longer mapped to key `F' but to key `L'. - In `ftdiff', key `x' toggles between layout modes: Either use the advance width (this is new and now the default) or the bounding box information to determine line breaks. - For all demo tools, the new command line option `-v' shows the version. - For the demo tools with a GUI, the new command line options `-w' and `-h' select the width and the height of the output window, respectively. - The `ttdebug' program was broken and has been reactivated. Note that this program is not compiled by default. ====================================================================== CHANGES BETWEEN 2.4.10 and 2.4.11 (2012-Dec-20) I. IMPORTANT BUG FIXES - Some vulnerabilities in the BDF implementation have been fixed. Users of this font format should upgrade. II. IMPORTANT CHANGES - Subpixel hinting support has been contributed by Infinality, based on Greg Hitchcock's whitepaper at https://www.microsoft.com/typography/cleartype/truetypecleartype.aspx Originally, it was a separate patch available from https://web.archive.org/web/20150710073951/http://www.infinality.net:80/blog/ and which has been integrated. Note that ClearType support is not completely implemented! In particular, full support for the options `compatible_widths', `symmetrical_smoothing, and `bgr' (via the GETINFO bytecode instruction) is missing. Activation of subpixel hinting support can be controlled with the `TT_CONFIG_OPTION_SUBPIXEL_HINTING' configuration option; it is switched off by default. This feature is still experimental; we welcome test reports! - Support for OpenType collections (OTC) has been added. - Pure CFF fonts within an SFNT wrapper are now supported. III. MISCELLANEOUS - Minor rendering improvements to the auto-hinter. - `FT_GlyphSlot_Oblique' now uses a shear angle of 12°. - Experimental support to handle `property modules', for example to control the behaviour of the auto-hinter. The API consists of two new functions, `FT_Property_Set' and `FT_Property_Get'. The code is still subject to change and should not be used for production. - The `ftdiff' demo program now supports UTF-8 encoded input files for option `-f'. - Using keys `r' and `R', you can now adjust the stroker radius in the `ftview' demo program. - Other, minor fixes and improvements. ====================================================================== CHANGES BETWEEN 2.4.9 and 2.4.10 (2012-Jun-15) I. IMPORTANT BUG FIXES - Incremental glyph loading as needed by ghostscript was broken. II. MISCELLANEOUS - A new function `FT_Outline_EmboldenXY', contributed by Alexei Podtelezhnikov. - In the `ftview' demo program, key `e' has been replaced with `x' and `y' to embolden in the horizontal and vertical direction, respectively. - The glyph spacing computation in `FT_GlyphSlot_Embolden' (and similar code in `ftview') has been improved. - Minor improvements to the TrueType bytecode interpreter and glyph loader, the auto-hinter, and the B/W rasterizer. ====================================================================== CHANGES BETWEEN 2.4.8 and 2.4.9 (2012-Mar-08) I. IMPORTANT BUG FIXES - Another round of fixes to better handle invalid fonts. Many of them are vulnerabilities (see CVE-2012-1126 up to CVE-2012-1144 and SA48320) so all users should upgrade. II. MISCELLANEOUS - The `ENCODING -1 <n>' format of BDF fonts is now supported. - For BDF fonts, support for the whole Unicode encoding range has been added. - Better TTF support for x_ppem != y_ppem. - `FT_Get_Advances' sometimes returned bogus values. - The demo programs no longer recognize and handle default suffixes; you now have to always specify the complete font name. - Better rendering and LCD mode cycling added to `ftview'. ====================================================================== CHANGES BETWEEN 2.4.7 and 2.4.8 (2011-Nov-14) I. IMPORTANT BUG FIXES - Some vulnerabilities in handling CID-keyed PostScript fonts have been fixed; see CVE-2011-3439. II. MISCELLANEOUS - Chris Liddell contributed a new API, `FT_Get_PS_Font_Value', to retrieve most of the dictionary keys in Type 1 fonts. ====================================================================== CHANGES BETWEEN 2.4.6 and 2.4.7 (2011-Oct-18) I. IMPORTANT BUG FIXES - Some vulnerabilities in handling Type 1 fonts have been fixed; see CVE-2011-3256. II. MISCELLANEOUS - FreeType now properly handles ZapfDingbats glyph names while constructing a Unicode character map (for fonts which don't have one). ====================================================================== CHANGES BETWEEN 2.4.5 and 2.4.6 (2011-Jul-29) I. IMPORTANT BUG FIXES - For TrueType based fonts, the ascender and descender values were incorrect sometimes (off by a pixel if the ppem value was not a multiple of 5). Depending on the use you might now experience a different layout; the change should result in better, more consistent line spacing. - Fix CVE-2011-0226 which causes a vulnerability while handling Type 1 fonts. - BDF fonts containing glyphs with negative values for ENCODING were incorrectly rejected. This bug has been introduced in FreeType version 2.2.0. - David Bevan contributed a major revision of the FreeType stroker code: . The behaviour of FT_STROKER_LINEJOIN_BEVEL has been corrected. . A new line join style, FT_STROKER_LINEJOIN_MITER_FIXED, has been introduced to support PostScript and PDF miter joins. . FT_STROKER_LINEJOIN_MITER_VARIABLE has been introduced as an alias for FT_STROKER_LINEJOIN_MITER. . Various stroking glitches has been fixed. II. MISCELLANEOUS - SFNT bitmap fonts which contain an outline glyph for `.notdef' only no longer set the FT_FACE_FLAG_SCALABLE flag. ====================================================================== CHANGES BETWEEN 2.4.4 and 2.4.5 (2011-Jun-25) I. IMPORTANT BUG FIXES - A rendering regression for second-order Bézier curves has been fixed, introduced in 2.4.3. II. IMPORTANT CHANGES - If autohinting is not explicitly disabled, FreeType now uses the autohinter if a TrueType based font doesn't contain native hints. - The load flag FT_LOAD_IGNORE_GLOBAL_ADVANCE_WIDTH has been made redundant and is simply ignored; this means that FreeType now ignores the global advance width value in TrueType fonts. III. MISCELLANEOUS - `FT_Sfnt_Table_Info' can now return the number of SFNT tables of a font. - Support for PCF files compressed with bzip2 has been contributed by Joel Klinghed. To make this work, the OS must provide a bzip2 library. - Bradley Grainger contributed project and solution files in Visual Studio 2010 format. - Again some fixes to better handle broken fonts. - Some improvements to the B/W rasterizer. - Fixes to the cache module to improve robustness. - Just Fill Bugs contributed (experimental) code to compute blue zones for CJK Ideographs, improving the alignment of horizontal stems at the top or bottom edges. - The `ftgrid' demo program can now display autohinter segments, to be toggled on and off with key `s'. ====================================================================== CHANGES BETWEEN 2.4.3 and 2.4.4 (2010-Nov-28) I. IMPORTANT BUG FIXES - UVS support (TrueType/OpenType cmap format 14) support is fixed. This regression has been introduced in version 2.4.0. II. MISCELLANEOUS - Detect tricky fonts (e.g. MingLiU) by the lengths and checksums of Type42-persistent subtables (`cvt ', `fpgm', and `prep') when a TrueType font without family name is given. The previous fix, introduced in 2.4.3, was too rigorous, causing many subsetted fonts (mainly from PDF files) displayed badly because FreeType forced rendering with the TrueType bytecode engine instead of the autohinter. - Better support for 64bit platforms. - More fixes to improve handling of broken fonts. ====================================================================== CHANGES BETWEEN 2.4.2 and 2.4.3 (2010-Oct-03) I. IMPORTANT BUG FIXES - Fix rendering of certain cubic, S-shaped arcs. This regression has been introduced in version 2.4.0. II. MISCELLANEOUS - To fix the above mentioned rendering issue, a new spline flattening algorithm has been introduced which speeds up both conic and cubic arcs. - Handling of broken fonts has been further improved. ====================================================================== CHANGES BETWEEN 2.4.1 and 2.4.2 (2010-Aug-06) I. IMPORTANT BUG FIXES - A stack overflow in CFF Type2 CharStrings interpreter is fixed. - Handling Type 42 font deallocation was broken; additionally, the library is now more robust against malformed Type 42 fonts. II. MISCELLANEOUS - Two new functions, `FT_Reference_Library' (in FT_MODULE_H) and `FT_Reference_Face' (in FT_FREETYPE_H), have been added to simplify life-cycle management. A counter gets initialized to 1 at the time an FT_Library (or FT_Face) structure is created. The two new functions increment the respective counter. `FT_Done_Library' and `FT_Done_Face' then only destroy a library or face if the counter is 1, otherwise they simply decrement the counter. ====================================================================== CHANGES BETWEEN 2.4.0 and 2.4.1 (2010-Jul-18) I. IMPORTANT CHANGES - A serious bug in the CFF font module prevented display of many glyphs in CFF fonts like `MinionPro-Regular.otf'. ====================================================================== CHANGES BETWEEN 2.3.12 and 2.4.0 (2010-Jul-12) I. IMPORTANT CHANGES - Since May 2010, all patents regarding the TrueType bytecode interpreter have expired worldwide. Consequently, we now define TT_CONFIG_OPTION_BYTECODE_INTERPRETER by default (and undefine TT_CONFIG_OPTION_UNPATENTED_HINTING). - A new function `FT_Library_SetLcdFilterWeights' is available to adjust the filter weights set by `FT_Library_SetLcdFilter'. II. MISCELLANEOUS - Thanks to many reports from Robert Święcki, FreeType's stability in handling broken or damaged fonts is much improved. - Support for LCD filter control has been added to the demo programs `ftdiff' and `ftview'. ====================================================================== CHANGES BETWEEN 2.3.11 and 2.3.12 I. IMPORTANT CHANGES - For `FT_Open_Face', new parameters are available to ignore preferred family names: FT_PARAM_TAG_IGNORE_PREFERRED_FAMILY and FT_PARAM_TAG_IGNORE_PREFERRED_SUBFAMILY. II. MISCELLANEOUS - Support for incremental font loading (controlled with the FT_CONFIG_OPTION_INCREMENTAL macro) is now active by default. - Better support for vertical metrics. - Various minor bug fixes. ====================================================================== CHANGES BETWEEN 2.3.10 and 2.3.11 I. IMPORTANT BUG FIXES - Version 2.3.10 broke PCF support. ====================================================================== CHANGES BETWEEN 2.3.10 and 2.3.9 I. IMPORTANT BUG FIXES - If all ASCII digits in a font have the same (unscaled) width, the autohinter respects this and won't change it. - TrueType fonts are now rasterized correctly if the horizontal and vertical resolution differ. - Type 1 fonts are now handled with increased precision internally to avoid serious rounding issues if non-integral coordinates are encountered. - Horizontally condensed CFF fonts (using the font matrix) were rendered incorrectly. This bug has been introduced after release 2.3.5. II. IMPORTANT CHANGES - Support for the SFNT cmap 13 table format (as defined by the new OpenType 1.6 specification) has been added. - B/W rasterization of well-hinted TrueType fonts at small sizes has been greatly improved. - Calculation of vertical metrics in OpenType fonts has been improved. III. MISCELLANEOUS - It is now possible to change the emboldening factor in the `ftview' demo program with keys `e' and `E'. - It is now possible to change the slant value in the `ftview' demo program with keys `s' and `S'. - The 5-levels grayscale mode of the `ftraster' module (which FreeType doesn't use by default) was broken since version 2.3.0. - Compilation of the `ftgrays' and `ftraster' modules was broken in stand-alone mode. - Various fixes for compilation on 64bit and 16bit architectures. ====================================================================== CHANGES BETWEEN 2.3.9 and 2.3.8 I. IMPORTANT BUG FIXES - Very unfortunately, FreeType 2.3.8 contained a change that broke its official ABI. The end result is that programs compiled against previous versions of the library, but dynamically linked to 2.3.8 can experience memory corruption if they call the `FT_Get_PS_Font_Info' function. We recommend all users to upgrade to 2.3.9 as soon as possible, or to downgrade to a previous release of the library if this is not an option. The origin of the bug is that a new field was added to the publicly defined `PS_FontInfoRec' structure. Unfortunately, objects of this type can be stack or heap allocated by callers of `FT_Get_PS_Font_Info', resulting in a memory buffer overwrite with its implementation in 2.3.8. If you want to know whether your code is vulnerable to this issue, simply search for the substrings `PS_FontInfo' and `PS_Font_Info' in your source code. If none is found, your code is safe and is not affected. The FreeType team apologizes for the problem. - The POSIX support of MacOS resource-fork fonts (Suitcase fonts and LaserWriter Type1 PostScript fonts) was broken in 2.3.8. If FreeType2 is built without Carbon framework, these fonts are not handled correctly. Version 2.3.7 didn't have this bug. - `FT_Get_Advance' (and `FT_Get_Advances') returned bad values for almost all font formats except TrueType fonts. - Fix a bug in the SFNT kerning table loader/parser which could crash the engine if certain malformed tables were encountered. - Composite SFNT bitmaps are now handled correctly. II. IMPORTANT CHANGES - The new functions `FT_Get_CID_Is_Internally_CID_keyed' and `FT_Get_CID_From_Glyph_Index' can be used to access CID-keyed CFF fonts via CID values. This code has been contributed by Michael Toftdal. III. MISCELLANEOUS - `FT_Outline_Get_InsideBorder' returns FT_STROKER_BORDER_RIGHT for empty outlines. This was incorrectly documented. - The `ftview' demo program now supports UTF-8 encoded strings. ====================================================================== CHANGES BETWEEN 2.3.8 and 2.3.7 I. IMPORTANT BUG FIXES - CID-keyed fonts in an SFNT wrapper were not handled correctly. - The smooth renderer produced truncated images (on the right) for outline parts with negative horizontal values. Most fonts don't contain outlines left to the y coordinate axis, but the effect was very noticeable for outlines processed with FT_Glyph_Stroke, using thick strokes. - `FT_Get_TrueType_Engine_Type' returned a wrong value if both configuration macros TT_CONFIG_OPTION_BYTECODE_INTERPRETER and TT_CONFIG_OPTION_UNPATENTED_HINTING were defined. - The `face_index' field in the `FT_Face' structure wasn't initialized properly after calling FT_Open_Face and friends with a positive face index for CFFs, WinFNTs, and, most importantly, for TrueType Collections (TTCs). II. IMPORTANT CHANGES - Rudimentary support for Type 1 fonts and CID-keyed Type 1 fonts in an SFNT wrapper has been added -- such fonts are used on the Mac. The core SFNT tables `TYP1' and `CID ' are passed to the PS Type 1 and CID-keyed PS font drivers; other tables (`ALMX', `BBOX', etc.) are not supported yet. - A new interface to extract advance values of glyphs without loading their outlines has been added. The functions are called `FT_Get_Advance' and `FT_Get_Advances'; they are defined in file `ftadvanc.h' (to be accessed as FT_ADVANCES_H). - A new function `FT_Get_FSType_Flags' (in FT_FREETYPE_H) has been contributed by David Bevan to access the embedding and subsetting restriction information of fonts. III. MISCELLANEOUS - FT_MulFix is now an inlined function; by default, assembler code is provided for x86 and ARM. See FT_CONFIG_OPTION_INLINE_MULFIX and FT_CONFIG_OPTION_NO_ASSEMBLER (in ftoption.h) for more. - The handling of `tricky' fonts (this is, fonts which don't work with the autohinter, needing the font format's hinting engine) has been generalized and changed slightly: . A new face flag FT_FACE_FLAG_TRICKY indicates that the font format's hinting engine is necessary for correct rendering. The macro FT_IS_TRICKY can be used to check this flag. . FT_LOAD_NO_HINTING is now ignored for tricky fonts. To really force raw loading of such fonts (without hinting), both FT_LOAD_NO_HINTING and FT_LOAD_NO_AUTOHINT must be used -- this is something which you probably never want to do. . Tricky TrueType fonts always use the bytecode interpreter, either the patented or unpatented version. - The function `FT_GlyphSlot_Own_Bitmap' has been moved from FT_SYNTHESIS_H to FT_BITMAP_H; it is now part of the `official' API. (The functions in FT_SYNTHESIS_H are still subject to change, however.) - In the `ftdiff' demo program you can now toggle the use of FT_LOAD_IGNORE_GLOBAL_ADVANCE_WIDTH with key `a'. ====================================================================== CHANGES BETWEEN 2.3.7 and 2.3.6 I. IMPORTANT BUG FIXES - If the library was compiled on an i386 platform using gcc, and compiler option -O3 was given, `FT_MulFix' sometimes returned incorrect results which could have caused problems with `FT_Request_Metrics' and `FT_Select_Metrics', returning an incorrect descender size. - Pure CFFs without subfonts were scaled incorrectly if the font matrix was non-standard. This bug has been introduced in version 2.3.6. - The `style_name' field in the `FT_FaceRec' structure often contained a wrong value for Type 1 fonts. This misbehaviour has been introduced in version 2.3.6 while trying to fix another problem. [Note, however, that this value is informative only since the used algorithm to extract it is very simplistic.] II. IMPORTANT CHANGES - Two new macros, FT_OUTLINE_SMART_DROPOUTS and FT_OUTLINE_EXCLUDE_STUBS, have been introduced. Together with FT_OUTLINE_IGNORE_DROPOUTS (which was ignored previously) it is now possible to control the dropout mode of the `raster' module (for B&W rasterization), using the `flags' field in the `FT_Outline' structure. - The TrueType bytecode interpreter now passes the dropout mode to the B&W rasterizer. This greatly increases the output for small ppem values of many fonts like `pala.ttf'. ====================================================================== CHANGES BETWEEN 2.3.6 and 2.3.5 I. IMPORTANT BUG FIXES - A bunch of potential security problems have been found. All users should update. - Microsoft Unicode cmaps in TrueType fonts are now always preferred over Apple cmaps. This is not a bug per se, but there exist some buggy fonts created for MS which have broken Apple cmaps. This affects only the automatic selection of FreeType; it's always possible to manually select an Apple Unicode cmap if desired. - Many bug fixes to the TrueType bytecode interpreter. - Improved Mac support. - Subsetted CID-keyed CFFs are now supported correctly. - CID-keyed CFFs with subfonts which are scaled in a non-standard way are now handled correctly. - A call to FT_Open_Face with `face_index' < 0 crashed FreeType if the font was a Windows (bitmap) FNT/FON. II. IMPORTANT CHANGES - The new function `FT_Get_CID_Registry_Ordering_Supplement' gives access to those fields in a CID-keyed font. The code has been contributed by Derek Clegg. - George Williams contributed code to validate the new `MATH' OpenType table (within the `otvalid' module). The `ftvalid' demo program has been extended accordingly. - An API for cmap 14 support (for Unicode Variant Selectors, UVS) has been contributed by George Williams. - A new face flag FT_FACE_FLAG_CID_KEYED has been added, together with a macro FT_IS_CID_KEYED which evaluates to 1 if the font is CID-keyed. III. MISCELLANEOUS - Build support for symbian has been contributed. - Better WGL4 glyph name support, contributed by Sergey Tolstov. - Debugging output of the various FT_TRACEX macros is now sent to stderr. - The `ftview' demo program now provides artificial slanting too. - The `ftvalid' demo program has a new option `-f' to select the font index. ====================================================================== CHANGES BETWEEN 2.3.5 and 2.3.4 I. IMPORTANT BUG FIXES - Some subglyphs in TrueType fonts were handled incorrectly due to a missing graphics state reinitialization. - Large .Z files (as distributed with some X11 packages) weren't handled correctly, making FreeType increase the heap stack in an endless loop. - A large number of bugs have been fixed to avoid crashes and endless loops with invalid fonts. II. IMPORTANT CHANGES - The two new cache functions `FTC_ImageCache_LookupScaler' and `FTC_SBit_Cache_LookupScaler' have been added to allow lookup of glyphs using an `FTC_Scaler' object; this makes it possible to use fractional pixel sizes in the cache. The demo programs have been updated accordingly to use this feature. - A new API `FT_Get_CMap_Format' has been added to get the cmap format of a TrueType font. This is useful in handling PDF files. The code has been contributed by Derek Clegg. - The auto-hinter now produces better output by default for non-Latin scripts like Indic. This was done by using the CJK hinting module as the default instead of the Latin one. Thanks to Rahul Bhalerao for this suggestion. - A new API `FT_Face_CheckTrueTypePatents' has been added to find out whether a given TrueType font uses patented bytecode instructions. The `ft2demos' bundle contains a new program called `ftpatchk' which demonstrates its usage. - A new API `FT_Face_SetUnpatentedHinting' has been added to enable or disable the unpatented hinter. - Support for Windows FON files in PE format has been contributed by Dmitry Timoshkov. III. MISCELLANEOUS - Vincent Richomme contributed Visual C++ project files for Pocket PCs. ====================================================================== CHANGES BETWEEN 2.3.4 and 2.3.3 I. IMPORTANT BUG FIXES - A serious bug in the handling of bitmap fonts (and bitmap strikes of outline fonts) has been introduced in 2.3.3. ====================================================================== CHANGES BETWEEN 2.3.3 and 2.3.2 I. IMPORTANT BUG FIXES - Remove a serious regression in the TrueType bytecode interpreter that was introduced in version 2.3.2. Note that this does not disable the improvements introduced to the interpreter in version 2.3.2, only some ill cases that occurred with certain fonts (though a few popular ones). - The auto-hinter now ignores single-point contours for computing blue zones. This bug created `wavy' baselines when rendering text with various fonts that use these contours to model mark-attach points (these are points that are never rasterized and are placed outside of the glyph's real outline). - The `rsb_delta' and `lsb_delta' glyph slot fields are now set to zero for mono-spaced fonts. Otherwise code that uses them would essentially ruin the fixed-advance property. - Fix CVE-2007-1351 which can cause an integer overflow while parsing BDF fonts, leading to a potentially exploitable heap overflow condition. II. MISCELLANEOUS - Fixed compilation issues on some 64-bit platforms (see ChangeLog for details). - A new demo program `ftdiff' has been added to compare TrueType hinting, FreeType's auto hinting, and rendering without hinting in three columns. ====================================================================== CHANGES BETWEEN 2.3.2 and 2.3.1 I. IMPORTANT BUG FIXES - FreeType returned incorrect kerning information from TrueType fonts when the bytecode interpreter was enabled. This happened due to a typo introduced in version 2.3.0. - Negative kerning values from PFM files are now reported correctly (they were read as 16-bit unsigned values from the file). - Fixed a small memory leak when `FT_Init_FreeType' failed for some reason. - The Postscript hinter placed and sized very thin and ghost stems incorrectly. - The TrueType bytecode interpreter has been fixed to get rid of most of the rare differences seen in comparison to the Windows font loader. II. IMPORTANT CHANGES - The auto-hinter now better deals with serifs and corner cases (e.g., glyph '9' in Arial at 9pt, 96dpi). It also improves spacing adjustments and doesn't change widths for non-spacing glyphs. - Many Mac-specific functions are deprecated (but still available); modern replacements have been provided for them. See the documentation in file `ftmac.h'. ====================================================================== CHANGES BETWEEN 2.3.1 and 2.3.0 I. IMPORTANT BUG FIXES - The TrueType interpreter sometimes returned incorrect horizontal metrics due to a bug in the handling of the SHZ instruction. - A typo in a security check introduced after version 2.2.1 prevented FreeType to render some glyphs in CFF fonts. ====================================================================== CHANGES BETWEEN 2.3.0 and 2.2.1 I. IMPORTANT BUG FIXES - The PCF font loader is now much more robust while loading malformed font files. - Various memory leaks have been found and fixed. - The TrueType name loader now deals properly with some fonts that encode their names in UTF-16 (the specification was vague, and the code incorrectly assumed UCS-4). - Fixed the TrueType bytecode loader to deal properly with subtle monochrome/gray issues when scaling the CVT. Some fonts exhibited bad rendering artifacts otherwise. - `FT_GlyphSlot_Embolden' now supports vertical layouts correctly (it mangled the vertical advance height). - Fixed byte endian issues of `ftmac.c' to support Mac OS X on i386. - The PFR font loader no longer erroneously tags font files without any outlines as FT_FACE_FLAG_SCALABLE. II. NEW API FUNCTIONS - `FT_Library_SetLcdFilter' allows you to select a special filter to be applied to the bitmaps generated by `FT_Render_Glyph' if one of the FT_RENDER_MODE_LCD and FT_RENDER_MODE_LCD_V modes has been selected. This filter is used to reduce color fringes; several settings are available through the FT_LCD_FILTER_XXX enumeration. Its declaration and documentation can be found in file `include/freetype/ftlcdfil.h' (to be accessed with macro FT_LCD_FILTER_H). IMPORTANT: This function returns an error (FT_Err_Unimplemented_Feature) in default builds of the library for patent reasons. See below. - `FT_Get_Gasp' allows you to query the flags of the TrueType `gasp' table for a given character pixel size. This is useful to duplicate the text rendering of MS Windows when the native bytecode interpreter is enabled (which isn't the default for other patent reasons). Its declaration and documentation can be found in file `include/freetype/ftgasp.h' (to be accessed with macro FT_GASP_H). III. IMPORTANT CHANGES - The auto-hinter has been tuned a lot to improve its results with serif fonts, resulting in much better font rendering of many web pages. - The unpatented hinter is now part of the default build of the library; we have added code to automatically support `tricky' fonts that need it. This means that FreeType should `just work' with certain Asian fonts, like MingLiU, which cannot properly be loaded without a bytecode interpreter, but which fortunately do not use any of the patented bytecode opcodes. We detect these fonts by name, so please report any font file that doesn't seem to work with FreeType, and we shall do what we can to support it in a next release. Note that the API hasn't changed, so you can still force unpatented hinting with a special parameter to `FT_Open_Face' as well. This might be useful in same cases; for example, a PDF reader might present a user option to activate it to deal with certain `tricky' embedded fonts which cannot be clearly identified. If you are a developer for embedded systems, you might want to disable* the feature to save code space by undefining TT_CONFIG_OPTION_UNPATENTED_HINTING in file `ftoption.h'. - LCD-optimized rendering is now disabled in all default builds of the library, mainly due to patent issues. For more information see: https://lists.gnu.org/archive/html/freetype/2006-09/msg00064.html A new configuration macro FT_CONFIG_OPTION_SUBPIXEL_RENDERING has been introduced in `ftoption.h'; manually define it in this file if you want to re-enable the feature. The change only affects the implementation, not the FreeType API. This means that clients don't need to be modified, because the library still generates LCD decimated bitmaps, but with the added constraint that R=G=B on each triplet. The displayed result should be equal to normal anti-aliased rendering. Additionally, if FT_CONFIG_OPTION_SUBPIXEL_RENDERING is not defined, the new `FT_Library_SetLcdFilter' function returns the FT_Err_Unimplemented_Feature error code. - Some computation bugs in the TrueType bytecode interpreter were found, which allow us to get rid of very subtle and rare differences we had experienced with the Windows renderer. - It is now possible to cross-compile the library easily. See the file `docs/INSTALL.CROSS' for details. - The file `src/base/ftmac.c' now contains code for Mac OS X only; its deprecated function `FT_GetFile_From_Mac_Font_Name' always returns an error even if the QuickDraw framework is available. The previous version has been moved to `builds/mac/ftmac.c'. Selecting configure option `--with-quickdraw-carbon' makes the build process use the original `ftmac.c' file instead of the Mac OS X-only version. IV. MISCELLANEOUS - Various performance and memory footprint optimizations have been performed on the TrueType and CFF font loaders, sometimes with very drastic benefits (e.g., the TrueType loader is now about 25% faster; FreeType should use less heap memory under nearly all conditions). - The anti-aliased rasterizer has been optimized and is now 15% to 25% percent faster than in previous versions, depending on content. - The Type 1 loader has been improved; as an example, it now skips top-level dictionaries properly. - Better support for Mac fonts on POSIX systems, plus compilation fixes for Mac OS X on ppc64 where `ftmac.c' cannot be built. - Configuration without `--with-old-mac-fonts' does not include `ftmac.c' (this was the behaviour in FreeType version 2.1.10). - The TrueTypeGX validator (gxvalid) checks the order of glyph IDs in the kern table. ====================================================================== CHANGES BETWEEN 2.2.1 and 2.2 I. IMPORTANT BUG FIXES - Various integer overflows have been fixed. - PFB fonts with MacOS resource fork weren't handled correctly on non-MacOS platforms. ====================================================================== CHANGES BETWEEN 2.2 and 2.1.10 (not released officially) I. IMPORTANT BUG FIXES - Vertical metrics for SFNT fonts were incorrect sometimes. - The FT_HAS_KERNING macro always returned 0. - CFF OpenType fonts didn't return correct vertical metrics for glyphs with outlines. - If FreeType was compiled without hinters, all font formats based on PS outlines weren't scaled correctly. II. IMPORTANT CHANGES - Version 2.2 no longer exposes its internals, this is, the header files located in the `include/freetype/internal' directory of the source package are not copied anymore by the `make install' command. Consequently, a number of rogue clients which directly access FreeType's internal functions and structures won't compile without modification. We provide patches for most of those rogue clients. See the following page for more information: https://www.freetype.org/freetype2/patches/rogue-patches.html Note that, as a convenience to our Unix desktop users, version 2.2 is binary compatible with FreeType 2.1.7, which means that installing this release on an existing distribution shall not break any working desktop. - FreeType's build mechanism has been redesigned. With GNU make it is now sufficient in most cases to edit two files: `modules.cfg', to select the library components, and the configuration file `include/freetype/config/ftoption.h' (which can be copied to the objects directory). Removing unused module directories to prevent its compilation and editing `include/freetype/config/ftmodule.h' is no longer necessary. - The LIGHT hinting algorithm produces more pleasant results. Also, using the FT_LOAD_TARGET_LIGHT flags within FT_Load_Glyph always forces auto-hinting, as a special exception. This allows you to experiment with it even if you have enabled the TrueType bytecode interpreter in your build. - The auto hinter now employs a new algorithm for CJK fonts, based on Akito Hirai's patch. Note that this only works for fonts with a Unicode charmap at the moment. - The following callback function types have changed slightly (by adding the `const' keyword where appropriate): FT_Outline_MoveToFunc FT_Outline_LineToFunc FT_Outline_ConicToFunc FT_Outline_CubicToFunc FT_SpanFunc FT_Raster_RenderFunc FT_Glyph_TransformFunc FT_Renderer_RenderFunc FT_Renderer_TransformFunc Note that this doesn't affect binary backward compatibility. - On MacOS, new APIs have been added as replacements for legacy APIs: `FT_New_Face_From_FSRef' for `FT_New_Face_From_FSSpec', and `FT_GetFile_From_Mac_ATS_Name' for `FT_GetFile_From_Mac_Name'. Legacy APIs are still available, if FreeType is built without disabling them. - A new API `FT_Select_Size' has been added to select a bitmap strike by its index. Code using other functions to select bitmap strikes should be updated to use this function. - A new API `FT_Get_SubGlyph_Info' has been added to retrieve subglyph data. This can be used by rogue clients which used to access the internal headers to get the corresponding data. - In 2.1.10, the behaviour of `FT_Set_Pixel_Sizes' was changed for BDF/PCF fonts, and only for them. This causes inconsistency. In this release, we undo the change. The intent of the change in 2.1.10 is to allow size selection through real dimensions, which can now be done through `FT_Request_Size'. - Some security issues were discovered and fixed in the CFF and Type 1 loader, causing crashes of FreeType by malformed font files. III. MISCELLANEOUS - The documentation for FT_LOAD_TARGET_XXX and FT_RENDER_MODE_XXX values now better reflects its usage and differences: One set is used to specify the hinting algorithm, the other to specify the pixel rendering mode. - `FT_New_Face' and `FT_New_Face_From_FSSpec' in ftmac.c have been changed to count supported scalable faces (sfnt, LWFN) only, and to return the number of available faces via face->num_faces. Unsupported bitmap faces (fbit, NFNT) are ignored. - builds/unix/configure has been improved for MacOS X. It now automatically checks available functions in Carbon library, and prepare to use newest functions by default. Options to specify the dependencies of each Carbon APIs (FSSpec, FSRef, old/new QuickDraw, ATS) are available too. By manual disabling of all QuickDraw functionality, FreeType can be built without `deprecated function' warnings on MacOS 10.4.x, but FT_GetFile_Mac_Name in ftmac.c then is changed to a dummy function, and returns an `unimplemented' error. For details see builds/mac/README. - SFNT cmap handling has been improved, mainly to run much faster with CJK fonts. - A new function `FT_Get_TrueType_Engine_Type (declared in `FT_MODULE_H') is provided to determine the status of the TrueType bytecode interpreter compiled into the library (patented, unpatented, unimplemented). - Vertical metrics of glyphs are synthesized if the font does not provide such information. You can tell whether the metrics are synthesized or not by checking the FT_FACE_FLAG_VERTICAL flag of the face. - The demo programs `ftview' and `ftstring' have been rewritten for better readability. `ftview' has a new switch `-p' to test FT_New_Memory_Face (instead of FT_New_Face). - FreeType now honours bit 1 in the `head' table of TrueType fonts (meaning `left sidebearing point at x=0'). This helps with some buggy fonts. - Rudimentary support for Adobe's new `SING Glyphlet' format. See https://www.adobe.com/content/dam/acom/en/devnet/font/pdfs/5148.SING_Tutorial.pdf for more information. - The `ftdump' program from the `ft2demos' bundle now shows some information about charmaps. It also supports a new switch `-v' to increase verbosity. - Better AFM support. This includes track kerning support. ====================================================================== CHANGES BETWEEN 2.1.10 and 2.1.9 I. IMPORTANT BUG FIXES - The size comparison for BDF and PCF files could fail sometimes. - Some CFF files were still not loaded correctly. Patch from Derek Noonburg. - The stroker still had some serious bugs. - Boris Letocha fixed a bug in the TrueType interpreter: The NPUSHW instruction wasn't skipped correctly in IF clauses. Some fonts like `Helvetica 75 Bold' failed. - Another serious bug in handling TrueType hints caused many distortions. It has been introduced in version 2.1.8, and it is highly recommended to upgrade. - FreeType didn't properly parse empty Type 1 glyphs. - An unbound dynamic buffer growth was fixed in the PFR loader. - Several bugs have been fixed in the cache sub-system. - FreeType behaved incorrectly when resizing two distinct but very close character pixel sizes through `FT_Set_Char_Size' (Savannah bug #12263). - The auto-hinter didn't work properly for fonts without a Unicode charmap -- it even refused to load the glyphs. II. IMPORTANT CHANGES - Many fixes have been applied to drastically reduce the amount of heap memory used by FreeType, especially when using memory-mapped font files (which is the default on Unix systems which support them). - The auto-hinter has been replaced with a new module, called the `auto-fitter'. It consumes less memory than its predecessor, and it is prepared to support non-latin scripts better in next releases. - George Williams contributed code to read kerning data from PFM files. - FreeType now uses the TT_NAME_ID_PREFERRED_FAMILY and TT_NAME_ID_PREFERRED_SUBFAMILY strings (if available) for setting family and style in SFNT fonts (patch from Kornfeld Eliyahu Peter). - A new API `FT_Sfnt_Table_Info' (in FT_TRUETYPE_TABLES_H) has been added to retrieve name and size information of SFNT tables. - A new API `FT_OpenType_Validate' (in FT_OPENTYPE_VALIDATE_H) has been added to validate OpenType tables (BASE, GDEF, GPOS, GSUB, JSTF). After validation it is no longer necessary to check for errors in those tables while accessing them. Note that this module might be moved to another library in the future to avoid a tight dependency between FreeType and the OpenType specification. - A new API in FT_BITMAP_H (`FT_Bitmap_New', `FT_Bitmap_Convert', `FT_Bitmap_Copy', `FT_Bitmap_Embolden', `FT_Bitmap_Done') has been added. Its use is to convert an FT_Bitmap structure in 1bpp, 2bpp, 4bpp, or 8bpp format into another 8bpp FT_Bitmap, probably using a different pitch, and to further manipulate it. - A new API `FT_Outline_Embolden' (in FT_OUTLINE_H) gives finer control how outlines are emboldened. - `FT_GlyphSlot_Embolden' (in FT_SYNTHESIS_H) now handles bitmaps also (code contributed by Chia I Wu). Note that this function is still experimental and may be replaced with a better API. - The method how BDF and PCF bitmap fonts are accessed has been refined. Formerly, FT_Set_Pixel_Sizes and FT_Set_Char_Size were synonyms in FreeType's BDF and PCF interface. This has changed now. FT_Set_Pixel_Sizes should be used to select the actual font dimensions (the `strike', which is the sum of the `FONT_ASCENT' and `FONT_DESCENT' properties), while FT_Set_Char_Size selects the `nominal' size (the `PIXELSIZE' property). In both functions, the width parameter is ignored. III. MISCELLANEOUS - The BDF driver no longer converts all returned bitmaps with a depth of 2bpp or 4bpp to a depth of 8bpp. The documentation has not mentioned this explicitly, but implementors might have relied on this after looking into the source files. - A new option `--ftversion' has been added to freetype-config to return the FreeType version. - The memory debugger has been updated to dump allocation statistics on all allocation sources in the library. This is useful to spot greedy allocations when loading and processing fonts. - We removed a huge array of constant pointers to constant strings in the `psnames' module. The problem was that compilations in PIC mode (i.e., when generating a Unix shared object/dll) put the array into the non-shared writable section of the library since absolute pointers are not relocatable by nature. This reduces the memory consumption by approximately 16KByte per process linked to FreeType. We now also store the array in a compressed form (as a trie) which saves about 20KByte of code as well. - Kirill Smelkov provided patches to make src/raster/ftraster.c compile stand-alone again. ====================================================================== CHANGES BETWEEN 2.1.9 and 2.1.8 I. IMPORTANT BUG FIXES - The function `FT_Get_CharMap_Index' was only declared, without any real code. For consistency, it has been renamed to `FT_Get_Charmap_Index'. (This function is needed to implement cmap caches.) - `FT_Outline_Get_BBox' sometimes returned incorrect values for conic outlines (e.g., for TrueType fonts). - Handling of `bhed' table has been fixed. - The TrueType driver with enabled byte code interpreter sometimes returned artifacts due to incorrect rounding. This bug has been introduced after version 2.1.4. - The BDF driver dropped the last glyph in the font. - The BDF driver now uses the DEFAULT_CHAR property (if available) to select a glyph shape for the undefined glyph. - The stroker failed for closed outlines and single points. II. IMPORTANT CHANGES - George Williams contributed code to handle Apple's font distortion technology found in GX fonts (`avar', `cvar', `fvar', and `gvar' tables; the Multiple Masters API has been slightly extended to cope with the new functionality). - The `FT_GlyphSlotRec' structure has been extended: The elements `lsb_delta' and `rsb_delta' give the difference between hinted and unhinted left and right side bearings if autohinting is active. Using those values can improve the inter-letter spacing considerably. See the documentation of `FT_GlyphSlotRec' and the `ftstring' demo program how to use it. - Loading TrueType and Type 1 fonts has been made much faster. - The stroker is no longer experimental (but the cache subsystem still is). III. MISCELLANEOUS - A new documentation file `formats.txt' describes various font formats supported (and not supported) by FreeType. ====================================================================== CHANGES BETWEEN 2.1.8 and 2.1.7 I. IMPORTANT BUG FIXES - The native TrueType hinter contained some bugs which prevented some fonts to be rendered correctly, most notably Legendum.otf. - The PostScript hinter now produces improved results. - The linear advance width and height values were incorrectly rounded, making them virtually unusable if not loaded with FT_LOAD_LINEAR_DESIGN. - Indexing CID-keyed CFF fonts is now working: The glyph index is correctly treated as a CID, similar to FreeType's CID driver module. Note that CID CMap support is still missing. - The FT_FACE_FLAG_GLYPH_NAMES flag is now set correctly for all font formats. - Some subsetted Type 1 fonts weren't parsed correctly. This bug has been introduced in 2.1.7. In summary, the Type 1 parser has become more robust. - Non-decimal numbers weren't parsed correctly in PS fonts. - The WinFNT driver now correctly reports FT_ENCODING_NONE for all but one encoding. Use the new FT_WinFNT_ID_XXX values together with `FT_Get_WinFNT_Header' to get the WinFNT charset ID. - The descender metrics (face->size->metrics.descender) for WinFNT bitmap fonts had the wrong sign. - The (emulated) `seac' support for CFF fonts was broken. - The `flex' operator didn't work for CFF fonts. - PS glyphs which use the `hintmask' operator haven't been rendered correctly in some cases. - Metrics for BDF and PCF bitmap font formats have been fixed. - Autohinting is now disabled for glyphs which are vertically distorted or mirrored (using a transformation matrix). This fixes a bug which produced zero-height glyphs. - The `freetype-config' script now handles --prefix and --exec-prefix correctly; it also returns the proper --rpath (or -R) value if FreeType has been built as a shared library. II. IMPORTANT CHANGES - Both PCF and BDF drivers now handle the SETWIDTH_NAME and ADD_STYLE_NAME properties. Values are appended to face->style_name; example: `Bold SemiCondensed'. - The PCF driver now handles bitmap fonts compressed with the LZW algorithm (extension .pcf.Z, compressed with `compress'). - A new API function `FT_Get_CMap_Language_ID' (declared in `tttables.h') is available to get the language ID of a TrueType/SFNT cmap. - The hexadecimal format of data after the `StartData' command in CID-keyed Type 1 fonts is now supported. While this can't occur in file-based fonts, it can happen in document-embedded resources of PostScript documents. - Embedded bitmaps in SFNT-based CFF fonts are now supported. - A simple API is now available to control FreeType's tracing mechanism if compiled with FT_DEBUG_LEVEL_TRACE. See the file `ftdebug.h' for more details. - YAMATO Masatake contributed improved handling of MacOS resource forks on non-MacOS platforms (for example, Linux can mount MacOS file systems). - Support for MacOS has been improved; there is now a new function `FT_New_Face_From_FSSpec' similar to `FT_New_Face' except that it accepts an FSSpec instead of a path. - The cache sub-system has been rewritten. - There is now support for deinstallation of faces. - A new API function `FTC_Manager_RemoveFaceID' has been added to delete all `idle' nodes that correspond to a given FTC_FaceID. All `locked' nodes (i.e., those with a reference count > 0), will be modified to prevent them from appearing in further lookups (they will be cleaned normally when their reference count reaches 0). - There is now support for point scaling (i.e., providing character sizes in points + dpis, instead of pixels). - Three abstract cache classes are now available: FTC_GCache: Used to store one glyph item per cache node, with the ability to group common attributes into `families'. This replaces the old FTC_GlyphCache class. FTC_ICache: Used to store one FT_Glyph per cache node. This extends FTC_GCache. Family definition, family comparison, and glyph loading are however left to sub-classes. FTC_SCache: Used to store up to 16 small bitmaps per cache node. This extends FTC_GCache. Family definition, family comparison and glyph loading are however left to sub-classes. - The file `src/cache/ftcbasic.c' implements: FTC_ImageCache: Extends FTC_ICache; implements family definitions and glyph loading similar to the old API. FTC_SBitCache: Extends FTC_SCache, implements family definitions and glyph loading similar to the old API Client applications should be able to extend FTC_GCache, FTC_ICache, or FTC_SCache much more easily (i.e., less code to write, and less callbacks). For example, one could envision caches that are capable of storing transformed (obliqued), stroked, emboldened, or colored glyph images. Use `ftcbasic.c' as an example. - All public APIs are now in `include/freetype/ftcache.h', (to be accessed as `FT_CACHE_H'). The contents of `include/freetype/cache/' is only needed by applications that wish to implement their own caches. - There were some major performance improvements through the use of various programming tricks. Cache hits are up to 70% faster than in the old code. - The FTC_CMapCache has been simplified. Charmaps can only be accessed by index right now. There is also a new API named `FT_Charmap_GetIndex' for this purpose. - The demo programs have been updated to the new code. The previous versions will not work with the current one. - Using an invalid face index in FT_Open_Face and friends now causes an error even if the font contains a single face only. III. MISCELLANEOUS - Wolfgang Domröse contributed support files for building FreeType on the Atari using the PureC compiler. Note that the Atari is a 16bit platform. - Vitaliy Pasternak contributed project files for VS.NET 2003. ====================================================================== CHANGES BETWEEN 2.1.7 and 2.1.6 I. IMPORTANT BUG FIXES - Updated to newest libtool version, fixing build problems on various platforms. - On Unix platforms, `make install' didn't copy the correct `ftconfig.h' file. Note that version 2.1.7 contains the same library C source code as version 2.1.6. ====================================================================== CHANGES BETWEEN 2.1.6 and 2.1.5 I. IMPORTANT BUG FIXES - The PFR font driver didn't load kerning tables correctly, and the functions in FT_PFR_H didn't work at all. - Type 1 font files in binary format (PFB) with an end-of-file indicator weren't accepted by the FreeType engine. - Fonts which contain /PaintType and /StrokeWidth no longer cause a segfault. This bug has been introduced in version 2.1.5. - Fonts loaded with FT_LOAD_RENDER no longer cause strange results. This bug has been introduced in version 2.1.5. - Some Windows (bitmap) FNT/FON files couldn't be handled correctly. II. IMPORTANT CHANGES - The internal module API has been heavily changed in favor of massive simplifications within the font engine. This also means that authors of third-party modules must adapt their code to the new scheme. NOTE: THE NEW SCHEME IS NOT COMPLETED YET. PLEASE WAIT UNTIL A FINAL ANNOUNCEMENT! - The PostScript parser has been enhanced to handle comments and strings correctly. Additionally, more syntax forms are recognized. - Added the optional unpatented hinting system for TrueType. It allows typefaces which need hinting to produce correct glyph forms (e.g., Chinese typefaces from Dynalab) to work acceptably without infringing Apple patents. This system is compiled only if TT_CONFIG_OPTION_COMPILE_UNPATENTED_HINTING is defined in ftoption.h (activated by default). III. MISCELLANEOUS - There is now a guard in the public header files to protect against inclusion of freetype.h from FreeType 1. - Direct inclusion of freetype.h and other public header files no longer works. You have to use the documented scheme #include <ft2build.h> #include FT_FREETYPE_H to load freetype.h with a symbolic name. This protects against renaming of public header files (which shouldn't happen but actually has, avoiding two public header files with the same name). ====================================================================== CHANGES BETWEEN 2.1.5 and 2.1.4 I. IMPORTANT BUG FIXES - Parsing the /CIDFontName field now removes the leading slash to be in sync with other font drivers. - gzip support was buggy. Some fonts could not be read. - Fonts which have nested subglyphs more than one level deep no longer cause a segfault. - Creation of synthetic cmaps for fonts in CFF format was broken partially. - Numeric font dictionary entries for synthetic fonts are no longer overwritten. - The font matrix wasn't applied to the advance width for Type1, CID, and CFF fonts. This caused problems when loading certain synthetic Type 1 fonts like `Helvetica Narrow'. - The test for the charset registry in BDF and PCF fonts is now case-insensitive. - FT_Vector_Rotate sometimes returned strange values due to rounding errors. - The PCF driver now returns the correct number of glyphs (including an artificial `notdef' glyph at index 0). - FreeType now supports buggy CMaps which are contained in many CJK fonts from Dynalab. - Opening an invalid font on a Mac caused a segfault due to double-freeing memory. - BDF fonts with more than 32768 glyphs weren't supported properly. II. IMPORTANT CHANGES - Accessing bitmap font formats has been synchronized. To do that the FT_Bitmap_Size structure has been extended to contain new fields `size', `x_ppem', and `y_ppem'. - The FNT driver now returns multiple faces, not multiple strikes. - The `psnames' module has been updated to the Adobe Glyph List version 2.0. - The `psnames' module now understands `uXXXX[X[X]]' glyph names. - The algorithm for guessing the font style has been improved. - For fonts in SFNT format, root->height is no longer increased if the line gap is zero. There exist fonts (containing e.g. form drawing characters) which intentionally have a zero line gap value. - ft_glyph_bbox_xxx flags are now deprecated in favour of FT_GLYPH_BBOX_XXX. - ft_module_xxx flags are now deprecated in favour of FT_MODULE_XXX. - FT_ENCODING_MS_{SJIS,GB2312,BIG5,WANSUNG,JOHAB} are now deprecated in favour of FT_ENCODING_{SJIS,GB2312,BIG5,WANSUNG,JOHAB} -- those encodings are not specific to Microsoft. III. MISCELLANEOUS - The autohinter has been further improved; for example, `m' glyphs now retain its vertical symmetry. - Partial support of Mac fonts on non-Mac platforms. - `make refdoc' (after first `make') builds the HTML documentation. You need Python for this. - The make build system should now work more reliably on DOS-like platforms. - Support for EMX gcc and Watson C/C++ compilers on MS-DOS has been added. - Better VMS build support. - Support for the pkg-config package by providing a `freetype.pc' file. - New configure option --with-old-mac-fonts for Darwin. - Some source files have been renamed (mainly to fit into the 8.3 naming scheme). ====================================================================== CHANGES BETWEEN 2.1.4 and 2.1.3 I. IMPORTANT BUG FIXES - Updated to newest libtool version, fixing build problems on various platforms. - A fix in the Gzip stream reader: It couldn't read certain .gz files properly due to a small typo. In certain cases, FreeType could also loop endlessly when trying to load tiny gzipped files. - The configure script now tries to use the system-wide zlib when it finds one (instead of the copy found in src/gzip). And `freetype-config' has been updated to return relevant flags in this case when invoked with `--libs' (e.g. `-lzlib'). - Certain fonts couldn't be loaded by 2.1.3 because they lacked a Unicode charmap (e.g. SYMBOL.TTF). FreeType erroneously rejected them. - The CFF loader was modified to accept fonts which only contain a subset of their reference charset. This prevented the correct use of PDF-embedded fonts. - The logic to detect Unicode charmaps has been modified. This is required to support fonts which include both 16-bit and 32-bit charmaps (like very recent asian ones) using the new 10 and 12 SFNT formats. - The TrueType loader now limits the depth of composite glyphs. This is necessary to prevent broken fonts to break the engine by blowing the stack with recursive glyph definitions. - The CMap cache is now capable of managing UCS-4 character codes that are mapped through extended charmaps in recent TrueType/OpenType fonts. - The cache sub-system now properly manages out-of-memory conditions instead of blindly reporting them to the caller. This means that it will try to empty the cache before restarting its allocations to see if that can help. - The PFR driver didn't return the list of available embedded bitmaps properly. - There was a nasty memory leak when using embedded bitmaps in certain font formats. II. IMPORTANT CHANGES - David Chester contributed some enhancements to the auto-hinter that significantly increase the quality of its output. The Postscript hinter was also improved in several ways. - The FT_RENDER_MODE_LIGHT render mode was implemented. - A new API function called `FT_Get_BDF_Property' has been added to FT_BDF_H to retrieve BDF properties from BDF _and_ PCF font files. THIS IS STILL EXPERIMENTAL, since it hasn't been properly tested yet. - A Windows FNT specific API has been added, mostly to access font headers. This is used by Wine. - TrueType tables without an `hmtx' table are now tolerated when an incremental interface is used. This happens for certain Type42 fonts passed from Ghostscript to FreeType. - The PFR font driver is now capable of returning the font family and style names when they are available (instead of the sole `FontID'). This is performed by parsing an undocumented portion of the font file! III. MISCELLANEOUS - The path stroker in FT_STROKER_H has entered beta stage. It now works very well, but its interface might change a bit in the future. More on this in later releases. - The documentation for FT_Size_Metrics didn't appear properly in the API reference. - The file docs/VERSION.DLL has been updated to explain versioning with FreeType (i.e., comparing release/libtool/so numbers, and how to use them in autoconf scripts). - The installation documentation has been seriously revamped. Everything is now in the `docs' directory. ====================================================================== CHANGES BETWEEN 2.1.3 and 2.1.2 I. IMPORTANT BUG FIXES - FT_Vector_Transform had been incorrectly modified in 2.1.2, resulting in incorrect transformations being applied (for example, rotations were processed in opposite angles). - The format 8 and 12 TrueType charmap enumeration routines have been fixed (FT_Get_Next_Char returned invalid values). - The PFR font driver returned incorrect advance widths if the outline and metrics resolution defined in the font file were different. - FT_Glyph_To_Bitmap now returns successfully when called with an FT_BitmapGlyph argument (it previously returned an error). - A bug in the Type 1 loader that prevented valid font bounding boxes to be loaded from multiple master fonts. - The SFNT validation code has been rewritten. FreeType can now load `broken' fonts that were usable on Windows, but not with previous versions of the library. - The computation of bearings in the BDF driver has been fixed. - The Postscript hinter crashed when trying to hint certain glyphs (more precisely, when trying to apply hints to an empty glyph outline). - The TrueType glyph loader now supports composites in `Apple format' (they differ slightly from Microsoft/OpenType ones in the way transformation offsets are computed). - FreeType was very slow at opening certain asian CID/CFF fonts, due to fixed increment in dynamic array re-allocations. This has been changed to exponential behaviour to get acceptable performance. II. IMPORTANT CHANGES - The PCF driver now supports gzip-compressed font files natively. This means that you will be able to use all these bitmap fonts that come with XFree86 with FreeType (and libXft/libXft2, by extension). - The automatic and postscript hinters have both been updated. This results in a relatively important increase of rendering quality since many nasty defaults have been suppressed. Please visit the web page: https://www.freetype.org/hinting/smooth-hinting.html for additional details on this topic. - The `load_flags' parameter of `FT_Load_Glyph' is now an FT_Int32 (instead of just being an FT_Int). This breaks source and binary compatibility for 16bit systems only, while retaining both of them for 32 and 64 bit ones. Some new flags have been added consequently: FT_LOAD_NO_AUTOHINT :: Disable the use of the auto-hinter (but not native format hinters). FT_LOAD_TARGET_NORMAL :: Hint and render for normal anti-aliased displays. FT_LOAD_TARGET_MONO :: Hint and render for 1-bit displays. FT_LOAD_TARGET_LCD :: Hint and render for horizontal RGB or BGR subpixel displays (like LCD screens). THIS IS STILL EXPERIMENTAL! FT_LOAD_TARGET_LCD_V :: Same as FT_LOAD_TARGET_LCD, for vertical subpixel displays (like rotated LCD screens). THIS IS STILL EXPERIMENTAL! FT_LOAD_MONOCHROME is still supported, but only affects rendering, not the hinting. Note that the `ftview' demo program available in the `ft2demos' package has been updated to support LCD-optimized display on non-paletted displays (under Win32 and X11). - The PFR driver now supports embedded bitmaps (all formats supported), and returns correct kerning metrics for all glyphs. - The TrueType charmap loader now supports certain `broken' fonts that load under Windows without problems. - The cache API has been slightly modified (it's still a beta!): - The type FTC_ImageDesc has been removed; it is now replaced by FTC_ImageTypeRec. Note that one of its fields is a `load_flag' parameter for FT_Load_Glyph. - The field `num_grays' of FT_SBitRec has been changed to `max_grays' in order to fit within a single byte. Its maximum value is thus 255 (instead of 256 as previously). III. MISCELLANEOUS - Added support for the DESTDIR variable during `make install'. This simplifies packaging of FreeType. - Included modified copies of the ZLib sources in `src/gzip' in order to support gzip-compressed PCF fonts. We do not use the system-provided zlib for now, though this is a probable enhancement for future releases. - The DocMaker tool used to generate the on-line API reference has been completely rewritten. It is now located in `src/tools/docmaker/docmaker.py'. Features: - better cross-referenced output - more polished output - uses Python regular expressions (though it didn't speed the program) - much more modular structure, which allows for different `backends' in order to generate HTML, XML, or whatever format. One can regenerate the API reference by calling: python src/tools/docmaker/docmaker.py \ --prefix=ft2 \ --title=FreeType-2.1.3 \ --output=<outputdirectory> include/freetype/.h \ include/freetype/config/.h \ include/freetype/cache/.h - A new, experimental, support for incremental font loading (i.e., loading of fonts where the glyphs are not in the font file itself, but provided by an external component, like a Postscript interpreter) has been added by Graham Asher. This is still work in progress, however. - A new, EXPERIMENTAL, path stroker has been added. It doesn't suffer from severe rounding errors and treat bezier arcs directly. Still work in progress (i.e. not part of the official API). See the file <freetype/ftstroker.h> for some of the details. - The massive re-formatting of sources and internal re-design is still under-way. Many internal functions, constants, and types have been renamed. ====================================================================== CHANGES BETWEEN 2.1.2 and 2.1.1 I. IMPORTANT BUG FIXES - Many font drivers didn't select a Unicode charmap by default when a new face was opened (with the FT_CONFIG_OPTION_USE_CMAPS options enabled), causing many applications to not be able to display text correctly with the 2.1.x releases. - The PFR driver had a bug in its composite loading code that produces incorrectly placed accents with many fonts. - The Type42 driver crashed sometimes due to a nasty bug. - The Type 1 custom encoding charmap didn't handle the case where the first glyph index wasn't 0. - A serious typo in the TrueType composite loader produced incorrectly placed glyphs in fonts like `Wingdings' and a few others. II. MISCELLANEOUS - The Win32 Visual C++ project file has been updated to include the PFR driver as well. - `freetype.m4' is now installed by default by `make install' on Unix systems. - The function FT_Get_PS_Font_Info now works with CID and Type42 fonts as well. ====================================================================== CHANGES BETWEEN 2.1.1 and 2.1.0 I. IMPORTANT BUG FIXES - The `version_info' returned by `freetype-config' in 2.1.0 returned an invalid value. It now returns 9:1:3 (2.0.9 returned 9:0:3). - Version 2.1.0 couldn't be linked against applications on Win32 and Amiga systems due to a new debug function that wasn't properly propagated to the system-specific directory in `builds'. - Various MacOS and Mac OS X specific fixes. - Fixed a bug in the TrueType charmap validation routines that made version 2.1.0 too restrictive -- many popular fonts have been rejected. - There was still a very small difference between the monochrome glyph bitmaps produced by FreeType 1.x and FreeType 2.x with the bytecode interpreter enabled. This was caused by an invalid flag setting in the TrueType glyph loader, making the rasterizer change its drop-out control mode. Now the results should _really_ be completely identical. - The TrueType name table loader has been improved to support many popular though buggy Asian fonts. It now ignores empty name entries, invalid pointer offsets and a few other incorrect subtleties. Moreover, name strings are now loaded on demand, which reduces the memory load of many faces (e.g. the ARIAL.TTF font file contains a 10kByte name table with 70 names). - Fixed a bug in the Postscript hinter that prevented family blues substitution to happen correctly. II. NEW FEATURES - Three new font drivers in this release: A BDF font driver, contributed by Franco Zappa Nardelli, heavily modified by Werner Lemberg. It also supports anti-aliased bitmaps (using a slightly extended BDF format). * A Type42 font driver, contributed by Roberto Alameda. It is still experimental but seems to work relatively well. * A PFR font driver, contributed by David Turner himself. It doesn't support PFR hinting -- note that BitStream has at least two patents on this format! III. MISCELLANEOUS - The cache sub-system has been optimized in important ways. Cache hits are now significantly faster. For example, using the CMap cache is about twice faster than calling FT_Get_Char_Index on most platforms. Similarly, using an SBit cache is about five times faster than loading the bitmaps from a bitmap file, and 300 to 500 times faster than generating them from a scalable format. Note that you should recompile your sources if you designed a custom cache class for the FT2 Cache subsystem, since the changes performed are source, but not binary, compatible. ====================================================================== CHANGES BETWEEN 2.1.0 and 2.0.9 I. IMPORTANT BUG FIXES - The TrueType bytecode interpreter has been fixed to produce _exactly_ the same output as FreeType 1.x. Previous differences were due to slightly distinct fixed-point computation routines used to perform dot products and vector length measurements. It seems that native TrueType hinting is _extremely_ sensitive to rounding errors. The required vector computation routines have been optimized and placed within the `ttinterp.c' file. - Fixed the parsing of accelerator tables in the PCF font driver. - Fixed the Type1 glyph loader routine used to compute the font's maximum advance width. II. NEW FEATURES - The `configure' script used on Unix systems has been modified to check that GNU Make is being used to build the library. Otherwise, it will display a message proposing to use the GNUMAKE environment variable to name it. The Unix-specific file README.UNX has been modified accordingly. III. MISCELLANEOUS - The FreeType License in `docs/FTL.TXT' has been updated to include a proposed preferred disclaimer. If you are using FreeType in your products, you are encouraged (but not mandated) to use the following text in your documentation: """ Portions of this software are copyright © 1996-2002 The FreeType Project (www.freetype.org). All rights reserved. """ - The default size of the render pool has been reduced to 16kByte. This shouldn't result in any noticeable performance penalty, unless you are using the engine as-is to render very large and complex glyphs. - The FreeType 2 redesign has begun. More information can be found at this URL: https://www.freetype.org/freetype2/redesign.html The following internal changes have been performed within the sources of this release: - Many internal types have been renamed to increase consistency. The following should be true, except for public types: * All structure types have a name ending in `Rec' (short for `record'). * A pointer-to-structure type has the same name as the structure, _without_ the `Rec' suffix. Example: typedef struct FooRec_ { ... } FooRec, Foo; - Many internal macros have been renamed to increase consistency. The following should be true: All macros have a name beginning with `FT_'. This required a few changes like ALLOC => FT_ALLOC FREE => FT_FREE REALLOC => FT_REALLOC * All macros are completely UPPERCASE. This required a few changes like: READ_Short => FT_READ_SHORT NEXT_Short => FT_NEXT_SHORT GET_ULongLE => FT_GET_ULONG_LE MEM_Set => FT_MEM_SET MEM_Copy => FT_MEM_COPY etc. * Whenever possible, all macro names follow the FT_<OBJECT>_<METHOD> pattern. For example ACCESS_Frame => FT_FRAME_ENTER FORGET_Frame => FT_FRAME_EXIT EXTRACT_Frame => FT_FRAME_EXTRACT RELEASE_Frame => FT_FRAME_RELEASE FILE_Pos => FT_STREAM_POS FILE_Seek => FT_STREAM_SEEK FILE_Read => FT_STREAM_READ FILE_ReadAt => FT_STREAM_READ_AT READ_Fields => FT_STREAM_READ_FIELDS - Many internal functions have been renamed to follow the FT_<Object>_<Method> pattern. For example: FT_Seek_Stream => FT_Stream_Seek FT_Read_Stream_At => FT_Stream_ReadAt FT_Done_Stream => FT_Stream_Close FT_New_Stream => FT_Stream_Open FT_New_Memory_Stream => FT_Stream_OpenMemory FT_Extract_Frame => FT_Stream_ExtractFrame Note that method names do not contain `_'. - The FT_ALLOC_ARRAY and FT_REALLOC_ARRAY have been replaced with FT_NEW_ARRAY and FT_RENEW_ARRAY which do not take a type as the fourth argument. Instead, the array element type size is computed automatically from the type of the target pointer used. - A new object class, FT_CMap, has been introduced. These internal objects are used to model character maps. This eases the support of additional charmap types within the engine. - A new configuration file named `ftstdlib.h' has been added to `include/freetype/config'. It is used to define aliases for _every_ routine of the ISO C library that the font engine uses. Each aliases has a `ft_' prefix (e.g. `ft_strlen' is an alias for `strlen'). This is used to ease the porting of FreeType 2 to exotic runtime environments where the ISO C Library isn't available (e.g. XFree86 extension modules). More details are available in the `ChangeLog' file. ====================================================================== CHANGES BETWEEN 2.0.9 and 2.0.8 I. IMPORTANT BUG FIXES - Certain fonts like `foxjump.ttf' contain broken name tables with invalid entries and wild offsets. This caused FreeType to crash when trying to load them. The SFNT `name' table loader has been fixed to be able to support these strange fonts. Moreover, the code in charge of processing this table has been changed to always favour Windows-formatted entries over other ones. Hence, a font that works on Windows but not on the Mac will load cleanly in FreeType and report accurate values for Family & PostScript names. - The CID font driver has been fixed. It unfortunately returned a Postscript Font name with a leading slash, as in `/MunhwaGothic-Regular'. - FreeType 2 should now compile fine on AIX 4.3.3 as a shared library. - A bug in the Postscript hinter has been found and fixed, removing un-even stem widths at small pixel sizes (like 14-17). This improves the quality of a certain number of Postscript fonts. II. NEW FEATURES - A new function named `FT_Library_Version' has been added to return the current library's major, minor, and patch version numbers. This is important since the macros FREETYPE_MAJOR, FREETYPE_MINOR, and FREETYPE_PATCH cannot be used when the library is dynamically linked by a program. - Two new APIs have been added: `FT_Get_First_Char' and `FT_Get_Next_Char'. Together, these can be used to iterate efficiently over the currently selected charmap of a given face. Read the API reference for more details. III. MISCELLANEOUS - The FreeType sources are under heavy internal re-factoring. As a consequence, we have created a branch named `STABLE' on the CVS to hold all future releases/fixes in the 2.0.x family. The HEAD branch now contains the re-factored sources and shouldn't be used for testing or packaging new releases. In case you would like to access the 2.0.9 sources from our CVS repository, use the tag `VER-2-0-9'. ====================================================================== CHANGES BETWEEN 2.0.8 and 2.0.7 I. IMPORTANT BUG FIXES - There was a small but nasty bug in `freetype-config.in' which caused the `freetype-config' script to fail on Unix. This didn't prevent the installation of the library or even its execution, but caused problems when trying to compile many Unix packages that depend on it. - Some TrueType or OpenType fonts embedded in PDF documents do not have a 'cmap', 'post' and 'name' as is required by the specification. FreeType no longer refuses to load such fonts. - Various fixes to the PCF font driver. ====================================================================== CHANGES BETWEEN 2.0.7 and 2.0.6 I. IMPORTANT BUG FIXES - Fixed two bugs in the Type 1 font driver. The first one resulted in a memory leak in subtle cases. The other one caused FreeType to crash when trying to load `.gsf' files (Ghostscript so-called Postscript fonts). (This made _many_ KDE applications crash on certain systems. FreeType _is_ becoming a critical system component on Linux :-) - Fixed a memory leak in the CFF font driver. - Fixed a memory leak in the PCF font driver. - Fixed the Visual C++ project file `builds/win32/visualc/freetype.dsp' since it didn't include the Postscript hinter component, causing errors at build time. - Fixed a small rendering bug in the anti-aliased renderer that only occurred when trying to draw thin (less than 1 pixel) strokes. - Fixed `builds/unix/freetype2.a4' which is used to generate a valid `freetype2.m4' for use with autoconf. - Fixed the OpenVMS Makefiles. II. MISCELLANEOUS - Added `configure' and `install' scripts to the top-level directory. A GNU-style installation is thus now easily possible with ./configure <options> make make install ====================================================================== CHANGES BETWEEN 2.0.6 and 2.0.5 I. IMPORTANT BUG FIXES - It wasn't possible to load embedded bitmaps when the auto-hinter was used. This is now fixed. - The TrueType font driver didn't load some composites properly (the sub-glyphs were slightly shifted, and this was only noticeable when using monochrome rendering). - Various fixes to the auto-hinter. They merely improve the output of sans-serif fonts. Note that there are still problems with serifed fonts and composites (accented characters). - All scalable font drivers erroneously returned un-fitted glyph advances when hinting was requested. This created problems for a number of layout applications. This is a very old bug that got undetected mainly because most test/demo program perform rounding explicitly or implicitly (through the cache). - `FT_Glyph_To_Bitmap' did erroneously modify the source glyph in certain cases. - `glnames.py' still contained a bug that made FreeType return invalid names for certain glyphs. - The library crashed when loading certain Type 1 fonts like `sadn.pfb' (`Stalingrad Normal'), which appear to contain pathetic font info dictionaries. - The TrueType glyph loader is now much more paranoid and checks everything when loading a given glyph image. This was necessary to avoid problems (crashes and/or memory overwrites) with broken fonts that came from a really buggy automatic font converter. II. IMPORTANT UPDATES AND NEW FEATURES - Important updates to the Mac-specific parts of the library. - The caching sub-system has been completely re-designed, and its API has evolved (the old one is still supported for backward compatibility). The documentation for it is not yet completed, sorry. For now, you are encouraged to continue using the old API. However, the ftview demo program in the ft2demos package has already been updated to use the new caching functions. - A new charmap cache is provided too. See `FTC_CMapCache'. This is useful to perform character code -> glyph index translations quickly, without the need for an opened FT_Face. - A NEW POSTSCRIPT HINTER module has been added to support native hints in the following formats: PostScript Type 1, PostScript CID, and CFF/CEF. Please test! Note that the auto-hinter produces better results for a number of badly-hinted fonts (mostly auto-generated ones) though. - A memory debugger is now part of the standard FreeType sources. To enable it, define FT_DEBUG_MEMORY in <freetype/config/ftoption.h>, and recompile the library. Additionally, define the _environment_ variable FT_DEBUG_MEMORY and run any program using FreeType. When the library is exited, a summary of memory footprints and possible leaks will be displayed. This works transparently with _any_ program that uses FreeType. However, you will need a lot of memory to use this (allocated blocks are never released to the heap to detect double deletes easily). III. MISCELLANEOUS - We are aware of subtle differences between the output of FreeType versions 1 and 2 when it comes to monochrome TrueType-hinted glyphs. These are most probably due to small differences in the monochrome rasterizers and will be worked out in an upcoming release. - We have decided to fork the sources in a `stable' branch, and an `unstable' one, since FreeType is becoming a critical component of many Unix systems. The next bug-fix releases of the library will be named 2.0.7, 2.0.8, etc., while the `2.1' branch will contain a version of the sources where we will start major reworking of the library's internals, in order to produce FreeType 2.2.0 (or even 3.0) in a more distant future. We also hope that this scheme will allow much more frequent releases than in the past. ====================================================================== CHANGES BETWEEN 2.0.5 and 2.0.4 NOTE THAT 2.0.5 DOES NOT CONTAIN THE POSTSCRIPT HINTER. THIS MODULE WILL BE PART OF THE NEXT RELEASE (EITHER 2.0.6 or 2.1) - Fixed a bug that made certain glyphs, like `Cacute', `cacute' and `lslash' unavailable from Unicode charmaps of Postscript fonts. This prevented the correct display of Polish text, for example. - The kerning table of Type 1 fonts was loaded by FreeType, when its AFM file was attached to its face, but the FT_FACE_FLAG_HAS_KERNING bit flags was not set correctly, preventing FT_Get_Kerning to return meaningful values. - Improved SFNT (TrueType & OpenType) charmap support. Slightly better performance, as well as support for the new formats defined by the OpenType 1.3 specification (8, 10, and 12) - Fixed a serious typo in `src/base/ftcalc.c' which caused invalid computations in certain rare cases, producing ugly artefacts. - The size of the EM square is computed with a more accurate algorithm for Postscript fonts. The old one caused slight errors with embedded fonts found in PDF documents. - Fixed a bug in the cache manager that prevented normal LRU behaviour within the cache manager, causing unnecessary reloads (for FT_Face and FT_Size objects only). - Added a new function named `FT_Get_Name_Index' to retrieve the glyph index of a given glyph name, when found in a face. - Added a new function named `FT_Get_Postscript_Name' to retrieve the `unique' Postscript font name of a given face. - Added a new public header size named FT_SIZES_H (or <freetype/ftsizes.h>) providing new FT_Size-management functions: FT_New_Size, FT_Activate_Size, FT_Done_Size. - Fixed a reallocation bug that generated a dangling pointer (and possibly memory leaks) with Postscript fonts (in src/psaux/psobjs.c). - Many fixes for 16-bit correctness. - Removed many pedantic compiler warnings from the sources. - Added an Amiga build directory in `builds/amiga'. ====================================================================== CHANGES BETWEEN 2.0.4 and 2.0.3 - Fixed a rather annoying bug that was introduced in 2.0.3. Namely, the font transformation set through FT_Set_Transform was applied twice to auto-hinted glyphs, resulting in incorrectly rotated text output. - Fixed _many_ compiler warnings. FT2 should now compile cleanly with Visual C++'s most pedantic warning level (/W4). It already compiled fine with GCC and a few other compilers. - Fixed a bug that prevented the linear advance width of composite TrueType glyphs to be correctly returned. - Fixed the Visual C++ project files located in `builds/win32/visualc' (previous versions used older names of the library). - Many 32-bit constants have an `L' appended to their value, in order to improve the 16-bitness of the code. Someone is actually trying to use FT2 on an Atari ST machine! - Updated the `builds/detect.mk' file in order to automatically build FT2 on AIX systems. AIX uses `/usr/sbin/init' instead of `/sbin/init' and wasn't previously detected as a Unix platform by the FreeType build system. - Updated the Unix-specific portions of the build system (new libtool version, etc.). - The SFNT kerning loader now ensures that the table is sorted (since some problem fonts do not meet this requirement). ======================================================================= CHANGES BETWEEN 2.0.3 and 2.0.2 I. CHANGES TO THE MODULES / FONT DRIVERS - THE AUTO-HINTER HAS BEEN SLIGHTLY IMPROVED, in order to fix several annoying artefacts, mainly: - Blue zone alignment of horizontal stems wasn't performed correctly, resulting in artefacts like the `d' being placed one pixel below the `b' in some fonts like Time New Roman. - Overshoot thresholding wasn't performed correctly, creating unpleasant artefacts at large character pixel sizes. - Composite glyph loading has been simplified. This gets rid of various artefacts where the components of a composite glyphs were not correctly spaced. These are the last changes to the current auto-hinting module. A new hinting sub-system is currently in the work in order to support native hints in Type 1 / CFF / OpenType fonts, as well as globally improve rendering. - The PCF driver has been fixed. It reported invalid glyph dimensions for the fonts available on Solaris. - The Type 1, CID and CFF drivers have been modified to fix the computation of the EM size. - The Type 1 driver has been fixed to avoid a dangerous bug that crashed the library with non-conforming fonts (i.e. ones that do not place the .notdef glyph at position 0). - The TrueType driver had a rather subtle bug (dangling pointer when loading composite glyphs) that could crash the library in rare occasions! II. HIGH-LEVEL API CHANGES - The error code enumeration values have been changed. An error value is decomposed in a generic error code, and a module number. see <freetype/fterrors.h> for details. - A new public header file has been introduced, named FT_TRIGONOMETRY_H (include/freetype/fttrigon.h), providing trigonometric functions to compute sines, cosines, arctangents, etc. with 16.16 fixed precision. The implementation is based on the CORDIC algorithm and is very fast while being sufficiently accurate. III. INTERNALS - Added BeOS-specific files in the old build sub-system. Note that no changes were required to compile the library with Jam. - The configuration is now capable of automatically detecting 64-bit integers on a set of predefined compilers (GCC, Visual C++, Borland C++) and will use them by default. This provides a small performance boost. - A small memory leak that happened when opening 0-sized files (duh!) have been fixed. - Fixed bezier stack depth bug in the routines provided by the FT_BBOX_H header file. Also fixed similar bugs in the rasterizers. - The outline bounding box code has been rewritten to use direct computations, instead of bezier sub-division, to compute the exact bounding box of glyphs. This is slightly slower but more accurate. - The build system has been improved and fixed, mainly to support `make' on Windows 2000 correctly, avoid problems with `make distclean' on non Unix systems, etc. - Hexadecimal constants have been suffixed with `U' to avoid problems with certain compilers on 64-bit platforms. - A new directory named `src/tools' has been created. It contains Python scripts and simple unit test programs used to develop the library. - The DocMaker tool has been moved from `docs' to `src/tools' and has been updated with the following: - Now accepts the `--title=XXXX' or `-t XXXX' option from the command line to set the project's name in the generated API reference. - Now accepts the `--output=DIR' or `-o DIR' option from the command line to set the output directory for all generated HTML files. - Now accepts the `--prefix=XXXX' or `-p XXX' option from the command line to set the file prefix to use for all generated HTML files. - Now generates the current time/data on each generated page in order to distinguish between versions. DocMaker can be used with other projects now, not only FT2 (e.g. MLib, FTLayout, etc.). ====================================================================== CHANGES BETWEEN 2.0.2 and 2.0.1 I. CHANGES TO THE MODULES / FONT DRIVERS - THE TRUETYPE BYTECODE INTERPRETER IS NOW TURNED OFF, in order to avoid legal problems with the Apple patents. It seems that we mistakenly turned this option on in previous releases of the build. Note that if you want to use the bytecode interpreter in order to get high-quality TrueType rendering, you will need to toggle by hand the definition of the TT_CONFIG_OPTION_BYTECODE_INTERPRETER macro in the file `include/freetype/config/ftoption.h'. - The CFF driver has been improved by Tom Kacvinsky and Sander van der Wal: * Support for `seac' emulation. * Support for `dotsection'. * Support for retrieving glyph names through `FT_Get_Glyph_Name'. The first two items are necessary to correctly a large number of Type 1 fonts converted to the CFF formats by Adobe Acrobat. - The Type 1 driver was also improved by Tom & others: * Better EM size computation. * Better support for synthetic (transformed) fonts. * The Type 1 driver returns the charstrings corresponding to each glyph in the `glyph->control_data' field after a call to `FT_Load_Glyph' (thanks Ha Shao). - Various other bugfixes, including the following: * Fixed a nasty memory leak in the Type 1 driver. * The autohinter and the pcf driver used static writable data when they shouldn't. * Many casts were added to make the code more 64-bits safe. It also now compiles on Windows XP 64-bits without warnings. * Some incorrect writable statics were removed in the `autohint' and `pcf' drivers. FreeType 2 now compiles on Epoc again. II. CHANGES TO THE HIGH-LEVEL API - The library header files inclusion scheme has been changed. The old scheme looked like: #include <freetype/freetype.h> #include <freetype/ftglyph.h> #include <freetype/ftcache.h> #include <freetype/cache/ftimage.h> Now you should use: #include <ft2build.h> #include FT_FREETYPE_H #include FT_GLYPH_H #include FT_CACHE_H #include FT_CACHE_IMAGE_H NOTE THAT THE OLD INCLUSION SCHEME WILL STILL WORK WITH THIS RELEASE. HOWEVER, WE DO NOT GUARANTEE THAT THIS WILL STILL BE TRUE IN THE NEXT ONE (A.K.A. FREETYPE 2.1). The file <ft2build.h> is used to define the header filename macros. The complete and commented list of macros is available in the API reference under the section name `Header File Macros' in Chapter I. For more information, see section I of the following document: https://www.freetype.org/freetype2/docs/tutorial/step1.html - Many, many comments have been added to the public source file in order to automatically generate the API Reference through the `docmaker.py' Python script. The latter has been updated to support the grouping of sections in chapters and better index sort. See: https://www.freetype.org/freetype2/docs/reference/ft2-toc.html III. CHANGES TO THE BUILD PROCESS - If you are not building FreeType 2 with its own build system (but with your own Makefiles or project files), you will need to be aware that the build process has changed a little bit. You don't need to put the `src' directory in the include path when compiling any FT2 component. Instead, simply put the component's directory in the current include path. So, if you were doing something like: cc -c -Iinclude -Isrc src/base/ftbase.c change the line to: cc -c -Iinclude -Isrc/base src/base/ftbase.c If you were doing something like: cd src/base cc -c -I../../include -I.. ftbase.c change it to: cd src/base cc -c -I../../include ftbase.c ====================================================================== CHANGES BETWEEN 2.0.1 and 2.0 2.0.1 introduces a few changes: - Fixed many bugs related to the support of CFF / OpenType fonts. These formats are now much better supported though there is still work planned to deal with charset tables and PDF-embedded CFF files that use the old `seac' command. - The library could not be compiled in debug mode with a very small number of C compilers whose pre-processors didn't implement the `##' directive correctly (i.e. per se the ANSI C specification!) An elegant fix was found. - Added support for the free Borland command-line C++ Builder compiler. Use `make setup bcc32'. Also fixed a few source lines that generated new warnings with BCC32. - Fixed a bug in FT_Outline_Get_BBox when computing the extrema of a conic Bezier arc. - Updated the INSTALL file to add IDE compilation. - Other minor bug fixes, from invalid Type 1 style flags to correct support of synthetic (obliqued) fonts in the auto-hinter, better support for embedded bitmaps in a SFNT font. - Fixed some problems with `freetype-config'. Finally, the `standard' scheme for including FreeType headers is now gradually changing, but this will be explained in a later release (probably 2.0.2). And very special thanks to Tom Kacvinsky and YAMANO-UCHI Hidetoshi for their contributions! ====================================================================== CHANGES BETWEEN beta8 and 2.0 - Changed the default installation path for public headers from `include/freetype' to `include/freetype2'. Also added a new `freetype-config' that is automatically generated and installed on Unix and Cygwin systems. The script itself is used to retrieve the current install path, C compilation flags as well as linker flags. - Fixed several small bugs: * Incorrect max advance width for fixed-pitch Type 1 fonts. * Incorrect glyph names for certain TrueType fonts. * The glyph advance was not copied when FT_Glyph_To_Bitmap was called. * The linearHoriAdvance and linearVertAdvance fields were not correctly returned for glyphs processed by the auto-hinter. * `type1z' renamed back to `type1'; the old `type1' module has been removed. - Revamped the build system to make it a lot more generic. This will allow us to re-use nearly un-modified in lots of other projects (including FreeType Layout). - Changed `cid' to use `psaux' too. - Added the cache sub-system. See <freetype/ftcache.h> as well as the sources in `src/cache'. Note that it compiles but is still untested for now. - Updated `docs/docmaker.py', a draft API reference is available at https://web.archive.org/web/20001215173400/http://www.freetype.org:80/ft2api.html. - Changed `type1' to use `psaux'. - Created a new module named `psaux' to hold the Type 1 & Type 2 parsing routines. It should be used by `type1', `cid', and `cff' in the future. - Fixed an important bug in `FT_Glyph_Get_CBox'. - Fixed some compiler warnings that happened since the TrueType bytecode decoder was deactivated by default. - Fixed two memory leaks: * The memory manager (16 bytes) isn't released in FT_Done_FreeType! * Using custom input streams, the copy of the original stream was never released. - Fixed the auto-hinter by performing automatic computation of the `filling direction' of each glyph. This is done through a simple and fast approximation, and seems to work (problems spotted by Werner though). The Arphic fonts are a lot nicer though there are still a lot of things to do to handle Asian fonts correctly. ====================================================================== BETA-8 (RELEASE CANDIDATE) CHANGES - Deactivated the TrueType bytecode interpreter by default. - Deactivated the `src/type1' font driver. Now `src/type1z' is used by default. - Updates to the build system. We now compile the library correctly under Unix system through `configure' which is automatically called on the first `make' invocation. - Added the auto-hinting module! Fixing some bugs here and there. - Found some bugs in the composite loader (seac) of the Type1-based font drivers. - Renamed the directory `freetype2/config' to `freetype2/builds' and updated all relevant files. - Found a memory leak in the `type1' driver. - Incorporated Tom's patches to support flex operators correctly in OpenType/CFF fonts. Now all I need is to support pure CFF and CEF fonts to be done with this driver :-) - Added the Windows FNT/FON driver in `src/winfonts'. For now, it always `simulates' a Unicode charmap, so it shouldn't be considered completed right now. It is there to be more a proof of concept than anything else anyway. The driver is a single C source file, that compiles to 3 Kb of code. I'm still working on the PCF/BDF drivers, but I'm too lazy to finish them now. - CHANGES TO THE HIGH-LEVEL API * FT_Get_Kerning has a new parameter that allows you to select the coordinates of the kerning vector (font units, scaled, scaled + grid-fitted). * The outline functions are now in <freetype/ftoutln.h> and not part of <freetype/freetype.h> anymore. * <freetype/ftmodule.h> now contains declarations for FT_New_Library, FT_Done_Library, FT_Add_Default_Modules. * The so-called convenience functions have moved from `ftoutln.c' to `ftglyph.c', and are thus available with this optional component of the library. They are declared in <freetype/ftglyph.h> now. * Anti-aliased rendering is now the default for FT_Render_Glyph (i.e. corresponds to render_mode == 0 == ft_render_mode_normal). To generate a monochrome bitmap, use ft_render_mode_mono, or the FT_LOAD_MONOCHROME flag in FT_Load_Glyph/FT_Load_Char. FT_LOAD_ANTI_ALIAS is still defined, but values to 0. * <freetype/freetype.h> now include <freetype/config/ftconfig.h>, solving a few headaches :-) * The type FT_GlyphSlotRec has now a `library' field. - CHANGES TO THE `ftglyph.h' API This API has been severely modified in order to make it simpler, clearer, and more efficient. It certainly now looks like a real `glyph factory' object, and allows client applications to manage (i.e. transform, bbox and render) glyph images without ever knowing their original format. - Added support for CID-keyed fonts to the CFF driver. Maybe support for pure CFF + CEF fonts should come in? - Cleaned up source code in order to avoid two functions with the same name. Also changed the names of the files in `type1z' from `t1XXXX' to `z1XXXX' in order to avoid any conflicts. `make multi' now works well :-) Also removed the use of `cidafm' for now, even if the source files are still there. This functionality will certainly go into a specific module. - ADDED SUPPORT FOR THE AUTO-HINTER It works :-) I have a demo program which simply is a copy of `ftview' that does a `FT_Add_Module(library, &autohinter_module_class)' after library initialization, and Type 1 & OpenType/CFF fonts are now hinted. CID fonts are not hinted, as they include no charmap and the auto-hinter doesn't include `generic' global metrics computations yet. Now, I need to release this thing to the FreeType 2 source. - CHANGES TO THE RENDERER MODULES The monochrome and smooth renderers are now in two distinct directories, namely `src/raster1' and `src/smooth'. Note that the old `src/renderer' is now gone. I ditched the 5-gray-levels renderers. Basically, it involved a simple #define toggle in 'src/raster1/ftraster.c'. FT_Render_Glyph, FT_Outline_Render & FT_Outline_Get_Bitmap now select the best renderer available, depending on render mode. If the current renderer for a given glyph image format isn't capable of supporting the render mode, another one will be found in the library's list. This means that client applications do not need to switch or set the renderers themselves (as in the latest change), they'll get what they want automatically. At last. Changed the demo programs accordingly. - MAJOR INTERNAL REDESIGN: A lot of internal modifications have been performed lately on the source in order to provide the following enhancements: * More generic module support: The FT_Module type is now defined to represent a handle to a given module. The file <freetype/ftmodule.h> contains the FT_Module_Class definition, as well as the module-loading public API. The FT_Driver type is still defined, and still represents a pointer to a font driver. Note that FT_Add_Driver is replaced by FT_Add_Module, FT_Get_Driver by FT_Get_Module, etc. * Support for generic glyph image types: The FT_Renderer type is a pointer to a module used to perform various operations on glyph image. Each renderer is capable of handling images in a single format (e.g. ft_glyph_format_outline). Its functions are used to: - transform an glyph image - render a glyph image into a bitmap - return the control box (dimensions) of a given glyph image The scan converters `ftraster.c' and `ftgrays.c' have been moved to the new directory `src/renderer', and are used to provide two default renderer modules. One corresponds to the `standard' scan-converter, the other to the `smooth' one. he current renderer can be set through the new function FT_Set_Renderer. The old raster-related function FT_Set_Raster, FT_Get_Raster and FT_Set_Raster_Mode have now disappeared, in favor of the new: FT_Get_Renderer FT_Set_Renderer See the file <freetype/ftrender.h> for more details. These changes were necessary to properly support different scalable formats in the future, like bi-color glyphs, etc. * Glyph loader object: A new internal object, called a 'glyph loader' has been introduced in the base layer. It is used by all scalable format font drivers to load glyphs and composites. This object has been created to reduce the code size of each driver, as each one of them basically re-implemented its functionality. See <freetype/internal/ftobjs.h> and the FT_GlyphLoader type for more information. * FT_GlyphSlot has new fields: In order to support extended features (see below), the FT_GlyphSlot structure has a few new fields: linearHoriAdvance: This field gives the linearly scaled (i.e. scaled but unhinted) advance width for the glyph, expressed as a 16.16 fixed pixel value. This is useful to perform WYSIWYG text. linearVertAdvance: This field gives the linearly scaled advance height for the glyph (relevant in vertical glyph layouts only). This is useful to perform WYSIWYG text. Note that the two above field replace the removed `metrics2' field in the glyph slot. advance: This field is a vector that gives the transformed advance for the glyph. By default, it corresponds to the advance width, unless FT_LOAD_VERTICAL_LAYOUT was specified when calling FT_Load_Glyph or FT_Load_Char. bitmap_left: This field gives the distance in integer pixels from the current pen position to the left-most pixel of a glyph image IF IT IS A BITMAP. It is only valid when the `format' field is set to `ft_glyph_format_bitmap', for example, after calling the new function FT_Render_Glyph. bitmap_top: This field gives the distance in integer pixels from the current pen position (located on the baseline) to the top-most pixel of the glyph image IF IT IS A BITMAP. Positive values correspond to upwards Y. loader: This is a new private field for the glyph slot. Client applications should not touch it. * Support for transforms and direct rendering in FT_Load_Glyph: Most of the functionality found in <freetype/ftglyph.h> has been moved to the core library. Hence, the following: - A transform can be specified for a face through FT_Set_Transform. this transform is applied by FT_Load_Glyph to scalable glyph images (i.e. NOT TO BITMAPS) before the function returns, unless the bit flag FT_LOAD_IGNORE_TRANSFORM was set in the load flags. - Once a glyph image has been loaded, it can be directly converted to a bitmap by using the new FT_Render_Glyph function. Note that this function takes the glyph image from the glyph slot, and converts it to a bitmap whose properties are returned in `face.glyph.bitmap', `face.glyph.bitmap_left' and `face.glyph.bitmap_top'. The original native image might be lost after the conversion. - When using the new bit flag FT_LOAD_RENDER, the FT_Load_Glyph and FT_Load_Char functions will call FT_Render_Glyph automatically when needed. - Reformatted all modules source code in order to get rid of the basic data types redefinitions (i.e. `TT_Int' instead of `FT_Int', `T1_Fixed' instead of `FT_Fixed'). Hence the format-specific prefixes like `TT_', `T1_', `T2_' and `CID_' are only used for relevant structures. ====================================================================== OLD CHANGES FOR BETA 7 - bug-fixed the OpenType/CFF parser. It now loads and displays my two fonts nicely, but I'm pretty certain that more testing is needed :-) - fixed the crummy Type 1 hinter, it now handles accented characters correctly (well, the accent is not always well placed, but that's another problem..) - added the CID-keyed Type 1 driver in `src/cid'. Works pretty well for only 13 Kb of code ;-) Doesn't read AFM files though, nor the really useful CMAP files.. - fixed two bugs in the smooth renderer (src/base/ftgrays.c). Thanks to Boris Letocha for spotting them and providing a fix. - fixed potential `divide by zero' bugs in ftcalc.c. - added source code for the OpenType/CFF driver (still incomplete though..) - modified the SFNT driver slightly to perform more robust header checks in TT_Load_SFNT_Header. This prevents certain font files (e.g. some Type 1 Multiple Masters) from being incorrectly `recognized' as TrueType font files.. - moved a lot of stuff from the TrueType driver to the SFNT module, this allows greater code re-use between font drivers (e.g. TrueType, OpenType, Compact-TrueType, etc..) - added a tiny segment cache to the SFNT Charmap 4 decoder, in order to minimally speed it up.. - added support for Multiple Master fonts in `type1z'. There is also a new file named <freetype/ftmm.h> which defines functions to manage them from client applications. The new file `src/base/ftmm.c' is also optional to the engine.. - various formatting changes (e.g. EXPORT_DEF -> FT_EXPORT_DEF) + small bug fixes in FT_Load_Glyph, the `type1' driver, etc.. - a minor fix to the Type 1 driver to let them apply the font matrix correctly (used for many oblique fonts..) - some fixes for 64-bit systems (mainly changing some FT_TRACE calls to use %p instead of %lx). Thanks to Karl Robillard. - fixed some bugs in the sbit loader (src/base/sfnt/ttsbit.c) + added a new flag, FT_LOAD_CROP_BITMAP to query that bitmaps be cropped when loaded from a file (maybe I should move the bitmap cropper to the base layer ??). - changed the default number of gray levels of the smooth renderer to 256 (instead of the previous 128). Of course, the human eye can't see any difference ;-) - removed TT_MAX_SUBGLYPHS, there is no static limit on the number of subglyphs in a TrueType font now.. ====================================================================== OLD CHANGES 16 May 2000 - tagged `BETA-6' in the CVS tree. This one is a serious release candidate even though it doesn't incorporate the auto-hinter yet.. - various obsolete files were removed, and copyright header updated - finally updated the standard raster to fix the monochrome rendering bug + re-enable support for 5-gray levels anti-aliasing (suck, suck..) - created new header files, and modified sources accordingly: <freetype/fttypes.h> - simple FreeType types, without the API <freetype/internal/ftmemory.h> - definition of memory-management macros - added the `DSIG' (OpenType Digital Signature) tag to <freetype/tttags.h> - light update/cleaning of the build system + changes to the sources in order to get rid of _all_ compiler warnings with three compilers, i.e: gcc with `-ansi -pedantic -Wall -W', Visual C++ with `/W3 /WX' and LCC IMPORTANT NOTE FOR WIN32-LCC USERS: \| \| It seems the C pre-processor that comes with LCC is broken, it \| doesn't recognize the ANSI standard directives # and ## \| correctly when one of the argument is a macro. Also, \| something like: \| \| #define F(x) print##x \| \| F(("hello")) \| \| will get incorrectly translated to: \| \| print "hello") \| \| by its pre-processor. For this reason, you simply cannot build \| FreeType 2 in debug mode with this compiler.. - yet another massive grunt work. I've changed the definition of the EXPORT_DEF, EXPORT_FUNC, BASE_DEF & BASE_FUNC macros. These now take an argument, which is the function's return value type. This is necessary to compile FreeType as a DLL on Windows and OS/2. Depending on the compiler used, a compiler-specific keyword like __export or __system must be placed before (VisualC++) or after (BorlandC++) the type.. Of course, this needed a lot of changes throughout the source code to make it compile again... All cleaned up now, apparently.. Note also that there is a new EXPORT_VAR macro defined to allow the _declaration_ of an exportable public (constant) variable. This is the case of the raster interfaces (see ftraster.h and ftgrays.h), as well as each module's interface (see sfdriver.h, psdriver.h, etc..) - new feature: it is now possible to pass extra parameters to font drivers when creating a new face object. For now, this capability is unused. It could however prove to be useful in a near future.. the FT_Open_Args structure was changes, as well as the internal driver interface (the specific `init_face' module function has now a different signature). - updated the tutorial (not finished though). - updated the top-level BUILD document - fixed a potential memory leak that could occur when loading embedded bitmaps. - added the declaration of FT_New_Memory_Face in <freetype/freetype.h>, as it was missing from the public header (the implementation was already in `ftobjs.c'). - the file <freetype/fterrors.h> has been seriously updated in order to allow the automatic generation of error message tables. See the comments within it for more information. - major directory hierarchy re-organisation. This was done for two things: * first, to ease the `manual' compilation of the library by requiring at lot less include paths :-) * second, to allow external programs to effectively access internal data fields. For example, this can be extremely useful if someone wants to write a font producer or a font manager on top of FreeType. Basically, you should now use the 'freetype/' prefix for header inclusion, as in: #include <freetype/freetype.h> #include <freetype/ftglyph.h> Some new include sub-directories are available: a. the `freetype/config' directory, contains two files used to configure the build of the library. Client applications should not need to look at these normally, but they can if they want. #include <freetype/config/ftoption.h> #include <freetype/config/ftconfig.h> b. the `freetype/internal' directory, contains header files that describes library internals. These are the header files that were previously found in the `src/base' and `src/shared' directories. As usual, the build system and the demos have been updated to reflect the change.. Here's a layout of the new directory hierarchy: TOP_DIR include/ freetype/ freetype.h ... config/ ftoption.h ftconfig.h ftmodule.h internal/ ftobjs.h ftstream.h ftcalc.h ... src/ base/ ... sfnt/ psnames/ truetype/ type1/ type1z/ Compiling a module is now much easier, for example, the following should work when in the TOP_DIR directory on an ANSI build: gcc -c -I./include -I./src/base src/base/ftbase.c gcc -c -I./include -I./src/sfnt src/sfnt/sfnt.c etc.. (of course, using -Iconfig/<system> if you provide system-specific configuration files). - updated the structure of FT_Outline_Funcs in order to allow direct coordinate scaling within the outline decomposition routine (this is important for virtual `on' points with TrueType outlines) + updates to the rasters to support this.. - updated the OS/2 table loading code in `src/sfnt/ttload.c' in order to support version 2 of the table (see OpenType 1.2 spec) - created `include/tttables.h' and `include/t1tables.h' to allow client applications to access some of the SFNT and T1 tables of a face with a procedural interface (see `FT_Get_Sfnt_Table') + updates to internal source files to reflect the change.. - some cleanups in the source code to get rid of warnings when compiling with the `-Wall -W -ansi -pedantic' options in gcc. - debugged and moved the smooth renderer to `src/base/ftgrays.c' and its header to `include/ftgrays.h' - updated TT_MAX_SUBGLYPHS to 96 as some CJK fonts have composites with up to 80 sub-glyphs !! Thanks to Werner ====================================================================== OLD CHANGES - 14-apr-2000 - fixed a bug in the TrueType glyph loader that prevented the correct loading of some CJK glyphs in mingli.ttf - improved the standard Type 1 hinter in `src/type1' - fixed two bugs in the experimental Type 1 driver in `src/type1z' to handle the new XFree86 4.0 fonts (and a few other ones..) - the smooth renderer is now complete and supports sub-banding to render large glyphs at high speed. However, it is still located in `demos/src/ftgrays.c' and should move to the library itself in the next beta. NOTE: The smooth renderer doesn't compile in stand-alone mode anymore, but this should be fixed RSN.. - introduced convenience functions to more easily deal with glyph images, see `include/ftglyph.h' for more details, as well as the new demo program named `demos/src/ftstring.c' that demonstrates its use - implemented FT_LOAD_NO_RECURSE in both the TrueType and Type 1 drivers (this is required by the auto-hinter to improve its results). - changed the raster interface, in order to allow client applications to provide their own span-drawing callbacks. However, only the smooth renderer supports this. See `FT_Raster_Params' in the file `include/ftimage.h'. - fixed a small bug in FT_MulFix that caused incorrect transform computation! - Note: The tutorial is out-of-date. ====================================================================== OLD CHANGES - 12-mar-2000 - changed the layout of configuration files : now, all ANSI configuration files are located in `freetype2/config'. System-specific over-rides can be placed in `freetype2/config/<system>'. - moved all configuration macros to `config/ftoption.h' - improvements in the Type 1 driver with AFM support - changed the fields in the FT_Outline structure : the old `flags' array is re-named `tags', while all ancient flags are encoded into a single unsigned int named `flags'. - introduced new flags in FT_Outline.flags (see ft_outline_.... enums in `ftimage.h'). - changed outline functions to `FT_Outline_<action>' syntax - added a smooth anti-alias renderer to the demonstration programs - added Mac graphics driver (thanks Just) - FT_Open_Face changed in order to received a pointer to a FT_Open_Args descriptor.. - various cleanups, a few more API functions implemented (see FT_Attach_File) - updated some docs ====================================================================== OLD CHANGES - 22-feb-2000 - introduced the `psnames' module. It is used to: o convert a Postscript glyph name into the equivalent Unicode character code (used by the Type 1 driver(s) to synthesize on the fly a Unicode charmap). o provide an interface to retrieve the Postscript names of the Macintosh, Adobe Standard & Adobe Expert character codes. (the Macintosh names are used by the SFNT-module postscript names support routines, while the other two tables are used by the Type 1 driver(s)). - introduced the `type1z' alternate Type 1 driver. This is a (still experimental) driver for the Type 1 format that will ultimately replace the one in `src/type1'. It uses pattern matching to load data from the font, instead of a finite state analyzer. It works much better than the `old' driver with `broken' fonts. It is also much smaller (under 15 Kb). - the Type 1 drivers (both in `src/type1' and `src/type1z') are nearly complete. They both provide automatic Unicode charmap synthesis through the `psnames' module. No re-encoding vector is needed. (note that they still leak memory due to some code missing, and I'm getting lazy). Trivial AFM support has been added to read kerning information but wasn't exactly tested as it should ;-) - The TrueType glyph loader has been seriously rewritten (see the file `src/truetype/ttgload.c'. It is now much, much simpler as well as easier to read, maintain and understand :-) Preliminary versions introduced a memory leak that has been reported by Jack Davis, and is now fixed.. - introduced the new `ft_glyph_format_plotter', used to represent stroked outlines like Windows `Vector' fonts, and certain Type 1 fonts like `Hershey'. The corresponding raster will be written soon. - FT_New_Memory_Face is gone. Likewise, FT_Open_Face has a new interface that uses a structure to describe the input stream, the driver (if required), etc.. TODO - Write FT_Get_Glyph_Bitmap and FT_Load_Glyph_Bitmap - Add a function like FT_Load_Character(face, char_code, load_flags) that would really embed a call to FT_Get_Char_Index then FT_Load_Glyph to ease developer's work. - Update the tutorial! - consider adding support for Multiple Master fonts in the Type 1 drivers. - Test the AFM routines of the Type 1 drivers to check that kerning information is returned correctly. - write a decent auto-gridding component !! We need this to release FreeType 2.0 gold ! less urgent needs: - add a CFF/Type2 driver - add a BDF driver - add a FNT/PCF/HBF driver - add a Speedo driver from the X11 sources ====================================================================== OLDER CHANGES - 27-jan-2000 - updated the `sfnt' module interface to allow several SFNT-based drivers to co-exist peacefully - updated the `T1_Face' type to better separate Postscript font content from the rest of the FT_Face structure. Might be used later by the CFF/Type2 driver.. - added an experimental replacement Type 1 driver featuring advanced (and speedy) pattern matching to retrieve the data from postscript fonts. - very minor changes in the implementation of FT_Set_Char_Size and FT_Set_Pixel_Sizes (they now implement default to lighten the font driver's code). ====================================================================== OLD MESSAGE This file summarizes the changes that occurred since the last `beta' of FreeType 2. Because the list is important, it has been divided into separate sections: Table Of Contents: I High-Level Interface (easier !) II Directory Structure III Glyph Image Formats IV Build System V Portability VI Font Drivers ---------------------------------------------------------------------- High-Level Interface: The high-level API has been considerably simplified. Here is how: - resource objects have disappeared. this means that face objects can now be created with a single function call (see FT_New_Face and FT_Open_Face) - when calling either FT_New_Face & FT_Open_Face, a size object and a glyph slot object are automatically created for the face, and can be accessed through `face->glyph' and `face->size' if one really needs to. In most cases, there's no need to call FT_New_Size or FT_New_Glyph. - similarly, FT_Load_Glyph now only takes a `face' argument (instead of a glyph slot and a size). Also, its `result' parameter is gone, as the glyph image type is returned in the field `face->glyph.format' - the list of available charmaps is directly accessible through `face->charmaps', counting `face->num_charmaps' elements. Each charmap has an 'encoding' field which specifies which known encoding it deals with. Valid values are, for example: ft_encoding_unicode (for ASCII, Latin-1 and Unicode) ft_encoding_apple_roman ft_encoding_sjis ft_encoding_adobe_standard ft_encoding_adobe_expert other values may be added in the future. Each charmap still holds its `platform_id' and `encoding_id' values in case the encoding is too exotic for the current library ---------------------------------------------------------------------- Directory Structure: Should seem obvious to most of you: freetype/ config/ -- configuration sub-makefiles ansi/ unix/ -- platform-specific configuration files win32/ os2/ msdos/ include/ -- public header files, those to be included directly by client apps src/ -- sources of the library base/ -- the base layer sfnt/ -- the sfnt `driver' (see the drivers section below) truetype/ -- the truetype driver type1/ -- the type1 driver shared/ -- some header files shared between drivers demos/ -- demos/tools docs/ -- documentation (a bit empty for now) ---------------------------------------------------------------------- Glyph Image Formats: Drivers are now able to register new glyph image formats within the library. For now, the base layer supports of course bitmaps and vector outlines, but one could imagine something different like colored bitmaps, bi-color vectors or whatever else (Metafonts anyone ??). See the file `include/ftimage.h'. Note also that the type FT_Raster_Map is gone, and is now replaced by FT_Bitmap, which should encompass all known bitmap types. Each new image format must provide at least one `raster', i.e. a module capable of transforming the glyph image into a bitmap. It's also possible to change the default raster used for a given glyph image format. The default outline scan-converter now uses 128 levels of grays by default, which tends to smooth many things. Note that the demo programs have been updated significantly in order to display these.. ---------------------------------------------------------------------- Build system: You still need GNU Make to build the library. The build system has been very seriously re-vamped in order to provide things like : - automatic host platform detection (reverting to 'config/ansi' if it is not detected, with pseudo-standard compilation flags) - the ability to compile from the Makefiles with very different and exotic compilers. Note that linking the library can be difficult for some platforms. For example, the file `config/win32/lcclib.bat' is invoked by the build system to create the `.lib' file with LCC-Win32 because its librarian has too many flaws to be invoked directly from the Makefile. Here's how it works: - the first time you type `make', the build system runs a series of sub-makefiles in order to detect your host platform. It then dumps what it found, and creates a file called `config.mk' in the current directory. This is a sub-Makefile used to define many important Make variables used to build the library. - the second time, the build system detects the `config.mk' then use it to build the library. All object files go into 'obj' by default, as well as the library file, but this can easily be changed. Note that you can run `make setup' to force another host platform detection even if a `config.mk' is present in the current directory. Another solution is simply to delete the file, then re-run make. Finally, the default compiler for all platforms is gcc (for now, this will hopefully changed in the future). You can however specify a different compiler by specifying it after the 'setup' target as in: gnumake setup lcc on Win32 to use the LCC compiler gnumake setup visualc on Win32 to use Visual C++ See the file `config/<system>/detect.mk' for a list of supported compilers for your platforms. It should be relatively easy to write new detection rules files and config.mk.. Finally, to build the demo programs, go to `demos' and launch GNU Make, it will use the `config.mk' in the top directory to build the test programs.. ---------------------------------------------------------------------- Portability: In the previous beta, a single FT_System object was used to encompass all low-level operations like thread synchronisation, memory management and i/o access. This has been greatly simplified: - thread synchronisation has been dropped, for the simple reason that the library is already re-entrant, and that if you really need two threads accessing the same FT_Library, you should really synchronize access to it yourself with a simple mutex. - memory management is performed through a very simple object called `FT_Memory', which really is a table containing a table of pointers to functions like malloc, realloc and free as well as some user data (closure). - resources have disappeared (they created more problems than they solved), and i/o management have been simplified greatly as a result. Streams are defined through FT_Stream objects, which can be either memory-based or disk-based. Note that each face has its own stream, which is closed only when the face object is destroyed. Hence, a function like TT_Flush_Face in 1.x cannot be directly supported. However, if you really need something like this, you can easily tailor your own streams to achieve the same feature at a lower level (and use FT_Open_Face instead of FT_New_Face to create the face). See the file `include/ftsystem.h' for more details, as well as the implementations found in `config/unix' and `config/ansi'. ---------------------------------------------------------------------- Font Drivers: The Font Driver interface has been modified in order to support extensions & versioning. The list of the font drivers that are statically linked to the library at compile time is managed through a new configuration file called `config/<platform>/ftmodule.h'. This file is autogenerated when invoking `make modules'. This target will parse all sub-directories of 'src', looking for a `module.mk' rules file, used to describe the driver to the build system. Hence, one should call `make modules' each time a font driver is added or removed from the `src' directory. Finally, this version provides a `pseudo-driver' in `src/sfnt'. This driver doesn't support font files directly, but provides services used by all TrueType-like font drivers. Hence, its code is shared between the TrueType & OpenType font formats, and possibly more formats to come if we're lucky.. ---------------------------------------------------------------------- Extensions support: The extensions support is inspired by the one found in 1.x. Now, each font driver has its own `extension registry', which lists which extensions are available for the font faces managed by the driver. Extension ids are now strings, rather than 4-byte tags, as this is usually more readable. Each extension has: - some data, associated to each face object - an interface (table of function pointers) An extension that is format-specific should simply register itself to the correct font driver. Here is some example code: // Registering an extensions // FT_Error FT_Init_XXXX_Extension( FT_Library library ) { FT_DriverInterface* tt_driver; driver = FT_Get_Driver( library, "truetype" ); if (!driver) return FT_Err_Unimplemented_Feature; return FT_Register_Extension( driver, &extension_class ); } // Implementing the extensions // FT_Error FT_Proceed_Extension_XXX( FT_Face face ) { FT_XXX_Extension ext; FT_XXX_Extension_Interface ext_interface; ext = FT_Get_Extension( face, "extensionid", &ext_interface ); if (!ext) return error; return ext_interface->do_it(ext); } ------------------------------------------------------------------------ Copyright (C) 2000-2022 by David Turner, Robert Wilhelm, and Werner Lemberg.

How to customize the compilation of the library =============================================== FreeType is highly customizable to fit various needs, and this document describes how it is possible to select options and components at compilation time. I. Configuration macros The file `include/freetype/config/ftoption.h' contains a list of commented configuration macros that can be toggled by developers to indicate which features should be active while building the library. These options range from debug level to availability of certain features, like native TrueType hinting through a bytecode interpreter. We invite you to read this file for more information. You can change the file's content to suit your needs, or override it with one of the techniques described below. II. Modules list If you use GNU make please edit the top-level file `modules.cfg'. It contains a list of available FreeType modules and extensions to be compiled. Change it to suit your own preferences. Be aware that certain modules depend on others, as described in the file. GNU make uses `modules.cfg' to generate `ftmodule.h' (in the object directory). If you build FreeType in a directory separate from the source files, put your customized `modules.cfg' in that directory; that way you can keep the source files `clean'. If you don't use GNU make you have to manually edit the file `include/freetype/config/ftmodule.h' (which is not used with if compiled with GNU make) to add or remove the drivers and components you want to compile into the library. See `INSTALL.ANY' for more information. III. System interface FreeType's default interface to the system (i.e., the parts that deal with memory management and i/o streams) is located in `src/base/ftsystem.c'. The current implementation uses standard C library calls to manage memory and to read font files. It is however possible to write custom implementations to suit specific systems. To tell the GNU Make-based build system to use a custom system interface, you have to define the environment variable FTSYS_SRC to point to the relevant implementation: on Unix: ./configure <your options> export FTSYS_SRC=foo/my_ftsystem.c make make install on Windows: make setup <compiler> set FTSYS_SRC=foo/my_ftsystem.c make IV. Overriding default configuration and module headers It is possible to override the default configuration and module headers without changing the original files. There are three ways to do that: 1. With GNU make [This is actually a combination of method 2 and 3.] Just put your custom `ftoption.h' file into the objects directory (normally `<topdir>/objs' if you build in the source tree, or the directory where you invoke configure if you build in a separate directory), which GNU make prefers over the standard location. No action is needed for `ftmodule.h' because it is generated automatically in the objects directory. 2. Using the C include path Use the C include path to ensure that your own versions of the files are used at compile time when the lines #include FT_CONFIG_OPTIONS_H #include FT_CONFIG_MODULES_H are compiled. Their default values being <freetype/config/ftoption.h> and <freetype/config/ftmodule.h>, you can do something like: custom/ config/ ftoption.h => custom options header ftmodule.h => custom modules list include/ => normal FreeType 2 include ... then change the C include path to always give the path to `custom' before the FreeType 2 `include'. 3. Redefining FT_CONFIG_OPTIONS_H and FT_CONFIG_MODULES_H Another way to do the same thing is to redefine the macros used to name the configuration headers. To do so, you need a custom `ft2build.h' whose content can be as simple as: #ifndef FT2_BUILD_MY_PLATFORM_H_ #define FT2_BUILD_MY_PLATFORM_H_ #define FT_CONFIG_OPTIONS_H <custom/my-ftoption.h> #define FT_CONFIG_MODULES_H <custom/my-ftmodule.h> #include <freetype/config/ftheader.h> #endif /* FT2_BUILD_MY_PLATFORM_H_ */ Place those files in a separate directory, e.g., custom/ ft2build.h => custom version described above my-ftoption.h => custom options header my-ftmodule.h => custom modules list header and change the C include path to ensure that `custom' is always placed before the FT2 `include' during compilation. ---------------------------------------------------------------------- Copyright (C) 2003-2022 by David Turner, Robert Wilhelm, and Werner Lemberg.

Debugging within the FreeType sources ===================================== I. Configuration macros ----------------------- There are several ways to enable debugging features in a FreeType 2 builds. This is controlled through the definition of special macros located in the file `ftoption.h'. The macros are: FT_DEBUG_LEVEL_ERROR #define this macro if you want to compile the `FT_ERROR' macro calls to print error messages during program execution. This does not stop the program. Very useful to spot invalid fonts during development and to code workarounds for them. FT_DEBUG_LEVEL_TRACE #define this macro if you want to compile both macros `FT_ERROR' and `FT_TRACE'. This also includes the variants `FT_TRACE0', `FT_TRACE1', `FT_TRACE2', ..., `FT_TRACE7'. The trace macros are used to send debugging messages when an appropriate `debug level' is configured at runtime through the `FT2_DEBUG' environment variable (more on this later). FT_DEBUG_MEMORY If this macro is #defined, the FreeType engine is linked with a small but effective debugging memory manager that tracks all allocations and frees that are performed within the font engine. When the `FT2_DEBUG_MEMORY' environment variable is defined at runtime, a call to `FT_Done_FreeType' dumps memory statistics, including the list of leaked memory blocks and optionally with the source locations where these were allocated. It is always a very good idea to define this in development builds. This works with _any_ program linked to FreeType, but requires a big deal of memory (the debugging memory manager never frees the blocks to the heap in order to detect double frees). When `FT2_DEBUG_MEMORY' isn't defined at runtime, the debugging memory manager is ignored, and performance is unaffected. FT_DEBUG_LOGGING #define this macro for enhanced logging support; it automatically sets `FT_DEBUG_LEVEL_TRACE' and `FT_DEBUG_LEVEL_ERROR'. If defined, `FT_TRACE' and `FT_ERROR' can send tracing and debugging messages to a file. The location of the log file has to be set with the `FT_LOGGING_FILE' environment variable (more on this later). The main enhancements are the possibility of logging the time and the name of the `FT_COMPONENT' macro together with the affected `FT_TRACE' or `FT_ERROR' calls. See below how to activate this in the `FT2_DEBUG' environment variable. II. Debugging macros -------------------- Several macros can be used within the FreeType sources to help debugging its code: 1. FT_ERROR(( ... )) This macro is used to send debug messages that indicate relatively serious errors (like broken font files) without stopping the execution of the running program. Its code is compiled only when either `FT_DEBUG_LEVEL_ERROR' or `FT_DEBUG_LEVEL_TRACE' are defined in `ftoption.h'. Note that you have to use a printf-like signature, but with double parentheses, like in FT_ERROR(( "your %s is not %s\n", "foo", "bar" )); 2. FT_ASSERT( condition ) This macro is used to check strong assertions at runtime. If its condition isn't TRUE, the program aborts with a panic message. Its code is compiled when either `FT_DEBUG_LEVEL_ERROR' or `FT_DEBUG_LEVEL_TRACE' are defined. You don't need double parentheses here. Example: FT_ASSERT( ptr != NULL ); 3. FT_TRACE( level, (message...) ) The `FT_TRACE' macro is used to send general-purpose debugging messages during program execution. This macro uses an implicit macro named `FT_COMPONENT', which names the current FreeType component being run. The developer should always define `FT_COMPONENT' as appropriate, for example as in #undef FT_COMPONENT #define FT_COMPONENT io The value of the `FT_COMPONENT' macro is one of the component names defined in the internal file `internal/fttrace.h'. If you modify the FreeType source code and insert a new `FT_COMPONENT' macro, you must register it in `fttrace.h'. If you insert or remove many trace macros, you can test for undefined or unused trace macros with the script `src/tools/chktrcmp.py'. Each such component is assigned a `debug level', ranging from value 0 to 7, through the use of the `FT2_DEBUG' environment variable (described below) when a program linked with FreeType starts. When `FT_TRACE' is called, its level is compared to the one of the corresponding component. Messages with trace levels higher than the corresponding component level are filtered out and never printed. This means that trace messages with level 0 are always printed, those with level 2 are only printed when the component level is at least 2, etc. The second parameter to `FT_TRACE' must contain parentheses and corresponds to a printf-like call, as in FT_TRACE( 2, ( "your %s is not %s\n", "foo", "bar" ) ) The shortcut macros `FT_TRACE0', `FT_TRACE1', `FT_TRACE2', ..., `FT_TRACE7' can be used with constant level indices, and are much cleaner to use, as in FT_TRACE2(( "your %s is not %s\n", "foo", "bar" )); III. Environment variables -------------------------- The following environment variables control debugging output and behaviour of FreeType at runtime. FT2_DEBUG This variable is only used when FreeType is built with `FT_DEBUG_LEVEL_TRACE' defined. It contains a list of component level definitions, following this format: component1:level1 component2:level2 component3:level3 ... where `componentX' is the name of a tracing component, as defined in `fttrace.h'. `levelX' is the corresponding level to use at runtime. `any' is a special component name that is interpreted as `any/all components'. For example, the following definitions set FT2_DEBUG=any:2 memory:5 io:4 (on Windows) export FT2_DEBUG="any:2 memory:5 io:4" (on Linux with bash) both stipulate that all components should have level 2, except for the memory and io components, which are set to the trace levels 5 and 4, respectively. If `FT_DEBUG_LOGGING' is defined, two more options are available. * -v: Print also the name of FreeType's component from which the current log is produced, together with the tracing level. * -t: Print also the time. Here are some examples how the output might look like. FT2_DEBUG="any:7 memory:5 -vt" => [20:32:02:44969 ttload:2] table directory loaded FT2_DEBUG="any:7 memory:5 -t" => [20:32:02:44969] table directory loaded FT2_DEBUG="any:7 memory:5 -v" => [ttload:2] table directory loaded FT_LOGGING_FILE This variable is only used if FreeType is built with the `FT_DEBUG_LOGGING' macro defined. It contains the path to the file where the user wants to put his log file. If it is not set, FreeType uses stderr. Examples: On UNIX-like systems with bash: export FT_LOGGING_FILE="/tmp/freetype2.log" On Windows: set FT_LOGGING_FILE=C:\Users\AppData\Local\Temp\freetype2.log FT2_DEBUG_MEMORY This environment variable, when defined, tells FreeType to use a debugging memory manager that tracks leaking memory blocks as well as other common errors like double frees. It is also capable of reporting _where_ the leaking blocks were allocated, which considerably saves time when debugging new additions to the library. This code is only compiled when FreeType is built with the `FT_DEBUG_MEMORY' macro #defined in `ftoption.h' though, it is ignored in other builds. FT2_ALLOC_TOTAL_MAX This variable is ignored if `FT2_DEBUG_MEMORY' is not defined. It allows you to specify a maximum heap size for all memory allocations performed by FreeType. This is very useful to test the robustness of the font engine and programs that use it in tight memory conditions. If it is undefined, or if its value is not strictly positive, no allocation bounds are checked at runtime. FT2_ALLOC_COUNT_MAX This variable is ignored if `FT2_DEBUG_MEMORY' is not defined. It allows you to specify a maximum number of memory allocations performed by FreeType before returning the error `FT_Err_Out_Of_Memory'. This is useful for debugging and testing the engine's robustness. If it is undefined, or if its value is not strictly positive, no allocation bounds are checked at runtime. FT2_KEEP_ALIVE This variable is ignored if `FT2_DEBUG_MEMORY' is not defined. `Keep alive' means that freed blocks aren't released to the heap. This is useful to detect double-frees or weird heap corruption, reporting the source code location of the original allocation and deallocation in case of a problem. It uses large amounts of memory, however. If it is undefined, or if its value is not strictly positive, freed blocks are released at runtime. IV. Additional Capabilities with `FT_DEBUG_LOGGING' --------------------------------------------------- If `FT_DEBUG_LOGGING' is defined, four APIs are available to provide additional debugging support. Use #include <freetype/ftlogging.h> to access them. FT_Trace_Set_Level( const char* level ) By default, FreeType uses the tracing levels set in the `FT2_DEBUG' environment variable. Use this function to override the value with `level'. Use value `NULL' to disable tracing. FT_Trace_Set_Default_Level(): Reset the tracing levels to the default value, i.e., the value of the `FT2_DEBUG' environment variable or no tracing if not set. FT_Set_Log_Handler( ft_custom_log_handler handler ): Use `handler' as a custom handler for formatting tracing and error messages. The `ft_custom_log_handler' typedef has the following prototype. void (ft_custom_log_handler)( const char ft_component, const char* fmt, va_list args ); `ft_component' is the current component like `ttload', `fmt' is the first argument of `FT_TRACE' or `FT_ERROR', and `args' holds the remaining arguments. FT_Set_Default_Log_Handler(): Reset the log handler to the default version. ------------------------------------------------------------------------ Copyright (C) 2002-2022 by David Turner, Robert Wilhelm, and Werner Lemberg.

Introduction ------------ Documentation is an extremely important part of any project, and it helps a lot if it uses consistent syntax and layout. The documentation for the FreeType library is maintained in header files in the `include/` directory in the form of code comments. These comments are extracted and organized by 'docwriter' (previously 'docmaker'). The generated docs can be viewed in the `docs/reference/site/` directory after running `make refdoc`. Documentation comments follow a specific structure and format as described below. Documentation Structure ----------------------- The documentation is divided into multiple chapters, which contain sections relevant to it. The chapter details and sections contained in them are listed in `include/freetype/ftchapters.h`. Any unlisted section is added to the 'Miscellaneous' chapter. Sections may contain sub-sections which consist of properties, enumerations, and other data types. Comment Blocks -------------- Documentation blocks follow a specific format: /***************************** (should end on column 77) * * (1 asterisk, 1 space, then content) * / (end of block) To make 'docwriter' recognize a comment block, there must be at least two asterisks in the first line. As a consequence, you should change the second asterisk to something else if you want to prevent a comment block being handled by 'docwriter' (for example, change `/**/` to `/#*/`). Markup Tags ----------- Markup tags are used to indicate what comes next. The syntax for a tag is: @foo: An `@`, followed by the tag, and then `:`. Reserved Tags ------------- There are some keywords that have a special meaning to docwriter. As a convention, all keywords are written in lowercase. `chapter`: Defines a chapter. Usually the title with underscores. * `sections`: List of sections in the chapter, in order. * `section`: Defines the start or continuation of a section. * `title`: Title for a chapter or section. May contain spaces. * `abstract`: The abstract for a section, visible in the Table of Contents (TOC). * `description`: Detailed description of a tag (except chapters), shown as synopsis. * `values`: A list of 'values' for the tag. These values are used for cross-referencing. Other Tags ---------- Except the ones given above, any other tags will be added as a part of a subsection. All tags are lowercase by convention. Public Header Definitions ------------------------- The public headers for FreeType have their names defined in `include/freetype/config/ftheader.h`. Any new public header file must be defined in this file, in the following format: #define FT_NEWNAME_H <freetype/newname.h> Where `newname` is the name of the header file. This macro is combined with the file location of a sub-section and printed with the object. Note on code blocks captured after comments ------------------------------------------- All non-documentation lines after a documentation comment block are captured to be displayed as the code for the sub-section. To stop collection, a line with `/* /` should be added. General Formatting Conventions ------------------------------ Use two spaces after a full stop ending a sentence. * Use appropriate uppercasing in titles. Refer https://english.stackexchange.com/a/34 for more information. * Do not add trailing parentheses when citing a C function. Markdown Usage -------------- All tags, except the ones that define the name and title for a block support markdown in them. Docwriter uses a markdown parser that follows rules given in John Gruber's markdown guide: https://daringfireball.net/projects/markdown/syntax with a few exceptions and extensions, detailed below. This may also be referred to as the FreeType Flavored Markdown. Headers ------- Markdown headers should not be used directly, because these are added based on section titles, sub-section names, and tags. However, if a header needs to be added, note the following correspondence to HTML tags: * Section title on top of the page is `H1`. * Sub-section titles are `H2`. * Parts of sub-sections are `H4`. * Any header added will be visible in the Table of Contents (TOC) of the page. Emphasis -------- * Use `_underscores_` for italics. * Use `double asterisks` for bold. Although the other notations (double underscore for bold, single asterisk for italics) are supported, it is recommended to use the above for consistency. Note that there may be cases where having two asterisks or underscores in a line may lead to text being picked up as italics or bold. Although unintentional, this is correct markdown behavior. For inline code, wrap the sequence with backticks (see below). This renders symbols correctly without modifications. If a symbol is absolutely required outside of an inline code block or code sequence, escape it with a backslash (like `\` or `\_`). Lists ----- Unordered lists can be created with asterisks: Unordered list items can use asterisks. * Another list item. Ordered lists start with numbers: 1. This is an ordered list item. 2. Brackets after numbers won't work. To continue a list over multiple paragraphs, indent them with at least four spaces. For example: 1. Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Aliquam hendrerit mi posuere lectus. Vestibulum enim wisi, viverra nec, fringilla in, laoreet vitae, risus. Donec sit amet nisl. Aliquam semper ipsum sit amet velit. Suspendisse id sem consectetuer libero luctus adipiscing. 2. This is the second list item. This paragraph is not a part of the list. More information on lists in markdown is available at https://daringfireball.net/projects/markdown/syntax#list Cross-references ---------------- Other sub-sections can be linked with the `@` symbol: @description: While FreeType's CFF driver doesn't expose API functions by itself, it is possible to control its behaviour with @FT_Property_Set and @FT_Property_Get. If a field in the `values` table of another sub-section is linked, the link leads to its parent sub-section. Links and Images ---------------- All URLs are converted to links in the HTML documentation. Markdown syntax for links and images are fully supported. Inline Code ----------- To indicate a span of code, wrap it with backtick quotes (`` ` ``): Use the `printf()` function. Cross-references, markdown, and html styling do not work in inline code sequences. Code and Syntax Highlighting ---------------------------- Blocks of code are fenced by lines with three back-ticks `` ``` `` followed by the language name, if any (used for syntax highlighting), as demonstrated in the following example. ```c x = y + z; if ( zookoo == 2 ) { foobar(); } ``` Note that the indentation of the opening line and the closing line must be exactly the same. The code sequence itself should have a larger indentation than the surrounding back-ticks. Like inline code, markdown and html styling is not supported inside code blocks. Tables ------ Tables are used to list values, input, and other fields. The FreeType Flavored Markdown adopts a simple approach to tables with two columns, or field definition tables. Field definition names may contain alphanumeric, underscore, and the `.` characters. This is followed by `::`. The following lines are the second column of the table. A field definition ends with the start of another field definition, or a markup tag. @Input: pathname :: A path to the font file. face_index :: See @FT_Open_Face for a detailed description of this parameter. Non-breaking Space ------------------ A tilde can be used to create a non-breaking space. The example The encoding value~0 is reserved. is converted to The encoding value 0 is reserved. ---------------------------------------------------------------------- Copyright (C) 2018-2022 by Nikhil Ramakrishnan, David Turner, Robert Wilhelm, and Werner Lemberg.

GNU GENERAL PUBLIC LICENSE Version 2, June 1991 Copyright (C) 1989, 1991 Free Software Foundation, Inc. 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Library General Public License instead.) You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow. GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. 10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. <one line to give the program's name and a brief idea of what it does.> Copyright (C) <year> <name of author> This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with this program; if not, write to the Free Software Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA Also add information on how to contact you by electronic and paper mail. If the program is interactive, make it output a short notice like this when it starts in an interactive mode: Gnomovision version 69, Copyright (C) year name of author Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details. The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, the commands you use may be called something other than `show w' and `show c'; they could even be mouse-clicks or menu items--whatever suits your program. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary. Here is a sample; alter the names: Yoyodyne, Inc., hereby disclaims all copyright interest in the program `Gnomovision' (which makes passes at compilers) written by James Hacker. <signature of Ty Coon>, 1 April 1989 Ty Coon, President of Vice This General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library. If this is what you want to do, use the GNU Library General Public License instead of this License.	whupdup/frame	real/third_party/freetype-2.12.0/docs/GPLv2.TXT	Text	gpl-3.0	17,994
There are several ways to build the FreeType library, depending on your system and the level of customization you need. Here is a short overview of the documentation available: I. Prerequisites and dependencies ================================= FreeType is a low level C library that only depends on the standard C library with very few platform-dependent optimizations utilized at build time. Any C99-compliant compiler should be able to compile FreeType. System libraries, such as zlib, Gzip, bzip2, Brotli, and libpng, might be used to handle compressed fonts or decode embedded PNG glyphs. FreeType auto-configuration scripts should be able to detect the prerequisites if the necessary headers are available at the default locations. Otherwise, modify `include/freetype/config/ftoption.h` to control how the FreeType library gets built. Normally, you don't need to change anything. Applications have very limited control over FreeType's behaviour at run-time; look at the documentation of function `FT_Property_Set`. II. Normal installation and upgrades ==================================== 1. Unix and Unix-like systems This also includes MacOS, Cygwin, MinGW + MSYS, Mingw-w64 + MSYS2, and possibly other, similar environments. Please read `INSTALL.UNIX` to install or upgrade FreeType 2 on a Unix system. Note that you need GNU Make for automatic compilation, since other make tools won't work (this includes BSD Make). GNU Make VERSION 3.81 OR NEWER IS NEEDED! 2. Other systems using GNU Make On some non-Unix platforms, it is possible to build the library using only the GNU Make utility. Note that NO OTHER MAKE TOOL WILL WORK[1]! This methods supports several compilers on Windows, OS/2, and BeOS, including MinGW* (without MSYS*), Visual C++, Borland C++, and more. Instructions are provided in the file `INSTALL.GNU`. 3. Other build tools and platforms. A few other tools can be used to build FreeType. You can find the corresponding instruction files in the FreeType root folder or the builds/ sub-folder. CMake :: see `CMakeLists.txt` for more information Meson :: see `meson.build` for more information MSBuild :: see `builds/windows/vc2010/freetype.vcxproj` MMS :: see `vms_make.com` and `docs/INSTALL.VMS` 4. With an IDE Project File (e.g., for Visual Studio or CodeWarrior) We provide a small number of 'project files' for various IDEs to automatically build the library as well. Note that these files are not actively supported by FreeType developers, they can break or become obsolete. To find them, have a look at the content of the `builds/<system>` directory, where <system> stands for your OS or environment. 5. From you own IDE, or own Makefiles If you want to create your own project file, follow the instructions given in the `INSTALL.ANY` document of this directory. III. Custom builds of the library ================================= Customizing the compilation of FreeType is easy, and allows you to select only the components of the font engine that you really need. For more details read the file `CUSTOMIZE`. ---------------------------------------------------------------------- [1] make++, a make tool written in Perl, has sufficient support of GNU make extensions to build FreeType. See https://makepp.sourceforge.net for more information; you need version 2.0 or newer, and you must pass option `--norc-substitution`. ---------------------------------------------------------------------- Copyright (C) 2000-2022 by David Turner, Robert Wilhelm, and Werner Lemberg.

Instructions on how to build FreeType with your own build tool ============================================================== See the file `CUSTOMIZE' to learn how to customize FreeType to specific environments. I. Standard procedure --------------------- * If you use macro names for FreeType header files (while mandatory in earlier versions, this is now optional since FreeType version 2.6.1) it is necessary to disable pre-compiled headers. This is very important for Visual C++, because lines like #include FT_FREETYPE_H are not correctly supported by this compiler while being ISO C compliant! * You need to add the directory `include' to your include path when compiling the library. * FreeType 2 is made of several components; each of them is located in a subdirectory of `freetype/src'. For example, `freetype/src/truetype/' contains the TrueType font driver. * DO NOT COMPILE ALL C FILES! Rather, compile the following ones. -- base components (required) src/base/ftsystem.c src/base/ftinit.c src/base/ftdebug.c src/base/ftbase.c src/base/ftbbox.c -- recommended, see <ftbbox.h> src/base/ftglyph.c -- recommended, see <ftglyph.h> src/base/ftbdf.c -- optional, see <ftbdf.h> src/base/ftbitmap.c -- optional, see <ftbitmap.h> src/base/ftcid.c -- optional, see <ftcid.h> src/base/ftfstype.c -- optional src/base/ftgasp.c -- optional, see <ftgasp.h> src/base/ftgxval.c -- optional, see <ftgxval.h> src/base/ftmm.c -- optional, see <ftmm.h> src/base/ftotval.c -- optional, see <ftotval.h> src/base/ftpatent.c -- optional src/base/ftpfr.c -- optional, see <ftpfr.h> src/base/ftstroke.c -- optional, see <ftstroke.h> src/base/ftsynth.c -- optional, see <ftsynth.h> src/base/fttype1.c -- optional, see <t1tables.h> src/base/ftwinfnt.c -- optional, see <ftwinfnt.h> src/base/ftmac.c -- only on the Macintosh -- font drivers (optional; at least one is needed) src/bdf/bdf.c -- BDF font driver src/cff/cff.c -- CFF/OpenType font driver src/cid/type1cid.c -- Type 1 CID-keyed font driver src/pcf/pcf.c -- PCF font driver src/pfr/pfr.c -- PFR/TrueDoc font driver src/sfnt/sfnt.c -- SFNT files support (TrueType & OpenType) src/truetype/truetype.c -- TrueType font driver src/type1/type1.c -- Type 1 font driver src/type42/type42.c -- Type 42 font driver src/winfonts/winfnt.c -- Windows FONT / FNT font driver -- rasterizers (optional; at least one is needed for vector formats) src/raster/raster.c -- monochrome rasterizer src/sdf/sdf.c -- Signed Distance Field driver src/smooth/smooth.c -- anti-aliasing rasterizer -- auxiliary modules (optional) src/autofit/autofit.c -- auto hinting module src/cache/ftcache.c -- cache sub-system (in beta) src/gzip/ftgzip.c -- support for compressed fonts (.gz) src/lzw/ftlzw.c -- support for compressed fonts (.Z) src/bzip2/ftbzip2.c -- support for compressed fonts (.bz2) src/gxvalid/gxvalid.c -- TrueTypeGX/AAT table validation src/otvalid/otvalid.c -- OpenType table validation src/psaux/psaux.c -- PostScript Type 1 parsing src/pshinter/pshinter.c -- PS hinting module src/psnames/psnames.c -- PostScript glyph names support Notes: `ftcache.c' needs `ftglyph.c' `ftfstype.c' needs `fttype1.c' `ftglyph.c' needs `ftbitmap.c' `ftstroke.c' needs `ftglyph.c' `ftsynth.c' needs `ftbitmap.c' `cff.c' needs `sfnt.c', `pshinter.c', and `psnames.c' `truetype.c' needs `sfnt.c' and `psnames.c' `type1.c' needs `psaux.c' `pshinter.c', and `psnames.c' `type1cid.c' needs `psaux.c', `pshinter.c', and `psnames.c' `type42.c' needs `truetype.c' Please consult the central `include/freetype/config/ftoption.h' configuration file for details on additional libraries necessary for some optional features. Read the file `CUSTOMIZE' in case you want to compile only a subset of the drivers, renderers, and optional modules; a detailed description of the various base extension is given in the top-level file `modules.cfg'. You are done. In case of problems, see the archives of the FreeType development mailing list. II. Support for flat-directory compilation ------------------------------------------ It is possible to put all FreeType 2 source files into a single directory, with the exception of the `include' hierarchy. 1. Copy all files in current directory cp freetype/src/base/.[hc] . cp freetype/src/raster1/.[hc] . cp freetype/src/smooth/*.[hc] . etc. 2. Compile sources cc -c -Iinclude -DFT2_BUILD_LIBRARY ftsystem.c cc -c -Iinclude -DFT2_BUILD_LIBRARY ftinit.c cc -c -Iinclude -DFT2_BUILD_LIBRARY ftdebug.c cc -c -Iinclude -DFT2_BUILD_LIBRARY ftbase.c etc. You don't need to define the FT_FLAT_COMPILATION macro (as this was required in previous releases of FreeType 2). ---------------------------------------------------------------------- Copyright (C) 2003-2022 by David Turner, Robert Wilhelm, and Werner Lemberg.

This document contains instructions on how to cross-build the FreeType library on Unix systems, for example, building binaries for Linux/MIPS on FreeBSD/i386. Before reading this document, please consult the file `INSTALL.UNIX' for required tools and the basic self-building procedure. 1. Required Tools ----------------- For self-building the FreeType library on a Unix system, GNU Make 3.81 or newer is required. `INSTALL.UNIX' contains hints how to check the installed `make'. The GNU C compiler to cross-build the target system is required. Currently, using a non-GNU cross compiler is untested. The cross compiler is expected to be installed with a system prefix. For example, if your building system is FreeBSD/i386 and the target system is Linux/MIPS, the cross compiler should be installed with the name `mips-ip22-linuxelf-gcc'. A C compiler for a self-build is required also, to build a tool (`apinames') that is executed during the build procedure. Non-GNU self compilers are acceptable, but such a setup is untested. 2. Configuration ---------------- 2.1. Building and target system To configure a cross-build, the options `--host=<system>' and `--build=<system>' must be passed to the `configure' script. For example, if your build system is FreeBSD/i386 and the target system is Linux/MIPS, say ./configure \ --build=i386-unknown-freebsd \ --host=mips-ip22-linuxelf \ [other options] It should be noted that `--host=<system>' specifies the system where the built binaries will be executed, not the system where the build actually happens. Older versions of GNU autoconf use the option pair `--host=' and `--target='. This is broken and doesn't work. Similarly, an explicit CC specification like env CC=mips-ip22-linux-gcc ./configure # BAD or env CC=/usr/local/mips-ip22-linux/bin/gcc ./configure # BAD doesn't work either; such a configuration confuses the `configure' script while trying to find the cross and native C compilers. 2.2. The prefix to install FreeType2 Setting `--prefix=<prefix>' properly is important. The prefix to install FreeType2 is written into the `freetype-config' script and `freetype2.pc' configuration file. If the built FreeType 2 library is used as a part of the cross-building system, the prefix is expected to be different from the self-building system. For example, a configuration with `--prefix=/usr/local' installs binaries into the system-wide `/usr/local' directory, which then can't be executed due to the incorrect architecture. This causes confusion in configuration of all applications that use FreeType2. Instead, use a prefix to install the cross-build into a separate system tree, for example, `--prefix=/usr/local/mips-ip22-linux/'. On the other hand, if the built FreeType 2 library is used as a part of the target system, the prefix to install should reflect the file system structure of the target system. 2.3. Library dependencies FreeType normally depends on external libraries like `libpng' or `libharfbuzz'. The easiest case is to deactivate all such dependencies using the `--without-XXX' configuration options. However, if you want to use those libraries, you should ensure that they are available both on the target system and as (cross-compiled) libraries on the build system. FreeType uses `pkg-config' to find most of the libraries; the other libraries it links to are expected in the standard system directories. Since the default pkg-config's meta-information files (like `harfbuzz.pc') of the build platform don't work, use one of the two possible solutions below. o Use pkg-config's meta-information files that are adjusted to cross-compile and cross-link with the target platform's libraries. Make sure those files are found before the build system's default files. Example: ./configure \ --build=i386-unknown-freebsd \ --host=mips-ip22-linuxelf \ PKG_CONFIG_LIBDIR="/usr/local/mips-ip22-linux/lib/pkgconfig" \ [other options] See the manpage of `pkg-config' for more details. o Set variables like LIBPNG_LIBS as additional options to the `configure' script, overriding the values `pkg-config' would provide. `configure --help' shows the available environment variables. Example: ./configure \ --build=i386-unknown-freebsd \ --host=mips-ip22-linuxelf \ LIBPNG_CFLAGS="-I/usr/local/mips-ip22-linux/include" \ LIBPNG_LIBS="-L/usr/local/mips-ip22-linux/lib -lpng12" \ [other options] 3. Building command ------------------- If the configuration finishes successfully, invoking GNU make builds FreeType2. Just say make or gmake depending on the name the GNU make binary actually has. 4. Installation --------------- Saying make install as usual to install FreeType2 into the directory tree specified by the argument of the `--prefix' option. As noted in section 2.2, FreeType2 is sometimes configured to be installed into the system directory of the target system, and should not be installed in the cross-building system. In such cases, the make variable `DESTDIR' is useful to change the root directory in the installation. For example, after make DESTDIR=/mnt/target_system_root/ install the built FreeType2 library files are installed into the directory `/mnt/target_system_root/<prefix_in_configure>/lib'. 5.

This document contains instructions how to build the FreeType library on non-Unix systems with the help of GNU Make. Note that if you are running Cygwin or MinGW/MSYS in Windows, you should follow the instructions in the file `INSTALL.UNIX' instead. FreeType 2 includes a powerful and flexible build system that allows you to easily compile it on a great variety of platforms from the command line. To do so, just follow these simple instructions. 1. Install GNU Make ------------------- The FreeType 2 build system relies on many features special to GNU Make. NEARLY ALL OTHER MAKE TOOLS FAIL, INCLUDING `BSD MAKE', SO REALLY INSTALL A RECENT VERSION OF GNU MAKE ON YOUR SYSTEM! Note that make++, a make tool written in Perl, supports enough features of GNU make to compile FreeType. See https://makepp.sourceforge.net for more information; you need version 2.0 or newer, and you must pass option `--norc-substitution'. Make sure that you are invoking GNU Make from the command line, by typing something like: make -v to display its version number. VERSION 3.81 OR NEWER IS NEEDED! 2. Invoke `make' ---------------- Go to the root directory of FreeType 2, then simply invoke GNU Make from the command line. This will launch the FreeType 2 host platform detection routines. A summary will be displayed, for example, on Win32. ============================================================== FreeType build system -- automatic system detection The following settings are used: platform windows compiler gcc configuration directory .\builds\windows configuration rules .\builds\windows\w32-gcc.mk If this does not correspond to your system or settings please remove the file 'config.mk' from this directory then read the INSTALL file for help. Otherwise, simply type 'make' again to build the library or 'make refdoc' to build the API reference (the latter needs Python >= 3.5). ============================================================= If the detected settings correspond to your platform and compiler, skip to step 5. Note that if your platform is completely alien to the build system, the detected platform will be `ansi'. 3. Configure the build system for a different compiler ------------------------------------------------------ If the build system correctly detected your platform, but you want to use a different compiler than the one specified in the summary (for most platforms, gcc is the default compiler), invoke GNU Make with make setup <compiler> Examples: to use Visual C++ on Win32, type: `make setup visualc' to use Borland C++ on Win32, type `make setup bcc32' to use Watcom C++ on Win32, type `make setup watcom' to use Intel C++ on Win32, type `make setup intelc' to use LCC-Win32 on Win32, type: `make setup lcc' to use Watcom C++ on OS/2, type `make setup watcom' to use VisualAge C++ on OS/2, type `make setup visualage' The <compiler> name to use is platform-dependent. The list of available compilers for your system is available in the file `builds/<system>/detect.mk'. If you are satisfied by the new configuration summary, skip to step 5. 3a. Use clang instead of gcc ---------------------------- The `clang' compiler can use FreeType's setup for `gcc'; it is sufficient to set the `CC' variable, for example make CC=clang 3b. Compiling with a C++ compiler --------------------------------- FreeType can be built with a C++ compiler, for example make CC="g++" If `clang++' should be used it is necessary to also override the `ANSIFLAGS' variable: make CC="clang++" ANSIFLAGS="" 4. Configure the build system for an unknown platform/compiler -------------------------------------------------------------- The auto-detection/setup phase of the build system copies a file to the current directory under the name `config.mk'. For example, on OS/2+gcc, it would simply copy `builds/os2/os2-gcc.mk' to `./config.mk'. If for some reason your platform isn't correctly detected, copy manually the configuration sub-makefile to `./config.mk' and go to step 5. Note that this file is a sub-Makefile used to specify Make variables for compiler and linker invocation during the build. You can easily create your own version from one of the existing configuration files, then copy it to the current directory under the name `./config.mk'. 5. Build the library -------------------- The auto-detection/setup phase should have copied a file in the current directory, called `./config.mk'. This file contains definitions of various Make variables used to invoke the compiler and linker during the build. [It has also generated a file called `ftmodule.h' in the objects directory (which is normally `<toplevel>/objs/'); please read the file `docs/CUSTOMIZE' for customization of FreeType.] To launch the build, simply invoke GNU Make again: The top Makefile will detect the configuration file and run the build with it. If you have used variables in step 3, you must use the same variables here, too. Final note The above instructions build a _statically_ linked library of the font engine in the `objs' directory. On Windows, you can build a DLL either with MinGW (within an MSYS shell, following the instructions in `INSTALL.UNIX'), or you use one of the Visual C++ project files; see the subdirectories of `builds/windows'. For everything else, you are on your own, and you might follow the instructions in `INSTALL.ANY' to create your own Makefiles. ---------------------------------------------------------------------- Copyright (C) 2003-2022 by David Turner, Robert Wilhelm, and Werner Lemberg.

Please follow the instructions in INSTALL.UNIX to install FreeType on Mac OS X. Currently FreeType2 functions based on some deprecated Carbon APIs return `FT_Err_Unimplemented_Feature' always, even if FreeType2 is configured and built on the system that deprecated Carbon APIs are available. To enable deprecated FreeType2 functions as far as possible, replace `src/base/ftmac.c' by `builds/mac/ftmac.c'. Starting with Mac OS X 10.5, gcc defaults the deployment target to 10.5. In previous versions of Mac OS X, this defaulted to 10.1. If you want your built binaries to run only on 10.5, this change does not concern you. If you want them to also run on older versions of Mac OS X, then you must either set the MACOSX_DEPLOYMENT_TARGET environment variable or pass `-mmacosx-version-min' to gcc. You should specify the oldest version of Mac OS you want the code to run on. For example, if you use Bourne shell: export MACOSX_DEPLOYMENT_TARGET=10.2 or, if you use C shell: setenv MACOSX_DEPLOYMENT_TARGET 10.2 Alternatively, you could pass `-mmacosx-version-min=10.2' to gcc. Here the number 10.2 is the lowest version that the built binaries can run on. In the above cases, the built binaries will run on Mac OS X 10.2 and later, but _not_ earlier. If you want to run on earlier, you have to set lower version, e.g., 10.0. For classic Mac OS (Mac OS 7, 8, 9) please refer to builds/mac/README.	whupdup/frame	real/third_party/freetype-2.12.0/docs/INSTALL.MAC	mac	gpl-3.0	1,466
This document contains instructions on how to build the FreeType library on Unix systems. This also works for emulations like Cygwin or MSys on Win32: 1. Ensure that you are using GNU Make ------------------------------------- The FreeType build system _exclusively_ works with GNU Make. You will not be able to compile the library with the instructions below using any other alternative (including BSD Make). Check that you have GNU make by running the command: make -v This should dump some text that begins with: GNU Make <version number> Copyright (C) <year> Free Software Foundation Inc. Note that version 3.81 or higher is required or the build will fail. It is also fine to have GNU Make under another name (e.g. 'gmake') if you use the MAKE variable as described below. As a special exception, 'makepp' can also be used to build FreeType 2. See the file docs/MAKEPP for details. For builds with `cmake' please check file `CMakeLists.txt'; this is a contributed file not directly supported by the FreeType team. 2. Regenerate the configure script if needed -------------------------------------------- This only applies if you are building a git snapshot or checkout, not if you grabbed the sources of an official release. You need to invoke the `autogen.sh' script in the top-level directory in order to create the `configure' script for your platform. Normally, this simply means typing: sh autogen.sh In case of problems, you may need to install or upgrade Automake, Autoconf or Libtool. See `README.git' in the top-level directory for more information. 3. Build and install the library -------------------------------- Say ./configure --help to see the list of possible configuration options and important environment variables. The ./configure script will detect some prerequisite system libraries (libpng, brotli, etc.) if their headers are available at the default locations. The following should work on all Unix systems where the `make' command invokes GNU Make: ./configure [options] make make install (as root) The default installation path is `/usr/local'. It can be changed with the `--prefix=<path>' option. Example: ./configure --prefix=/usr When using a different command to invoke GNU Make, use the MAKE variable. For example, if `gmake' is the command to use on your system, do something like: MAKE=gmake ./configure [options] gmake gmake install (as root) If this still doesn't work, there must be a problem with your system (e.g., you are using a very old version of GNU Make). For library identification, FreeType's `configure' script uses the `pkg-config' interface: Assuming it needs library `foo', it calls the `pkg-config' program to find information on library `foo', which in turn looks for a `foo.pc' file installed at the system. Some platforms, however, don't come with `pkg-support'; you then have to use environment variables as described by `configure --help'. Example: LIBPNG_CFLAGS="-I/path/to/libpng/include/directory" \ LIBPNG_LIBS="-L/path/to/libpng/lib/directory" \ configure ... It is possible to compile FreeType in a different directory. Assuming the FreeType source files in directory `/src/freetype' a compilation in directory `foo' works as follows: cd foo /src/freetype/configure [options] make make install 3.1 Interdependency with HarfBuzz ................................. Note that there is a chicken-and-egg problem currently since the HarfBuzz library (used by the auto-hinter to improve support of OpenType fonts) depends on FreeType, which can be solved as follows in case HarfBuzz is not yet installed on your system. 1. Call FreeType's `configure' script with option `--without-harfbuzz', then compile and install FreeType. 2. Compile and install HarfBuzz. 3. Call FreeType's `configure' script without option `--without-harfbuzz' (after executing `make distclean'), then compile and install FreeType again. ---------------------------------------------------------------------- Copyright (C) 2003-2022 by David Turner, Robert Wilhelm, and Werner Lemberg.

How to build the FreeType 2 library on VMS ----------------------------------------- It is actually very straightforward to install the FreeType 2 library. Just execute vms_make.com from the toplevel directory to build the library. This procedure currently accepts the following options: DEBUG Build the library with debug information and without optimization. lopts=<value> Options to pass to the link command e.g. lopts=/traceback ccopt=<value> Options to pass to the C compiler e.g. ccopt=/float=ieee In case you did download the demos, place them in a separate directory sharing the same top level as the directory of FreeType 2 and follow the same instructions as above for the demos from there. The build process relies on this to figure out the location of the FreeType 2 include files. To rebuild the sources it is necessary to have MMS/MMK installed on the system. The library is available in the directory [.LIB] To compile applications using FreeType 2 you have to define the logical FREETYPE pointing to the directory [.INCLUDE.FREETYPE] i.e., if the directory in which this INSTALL.VMS file is located is $disk:[freetype] then define the logical with define freetype $disk:[freetype.include.freetype] This version has been tested with Compaq C V6.2-006 on OpenVMS Alpha V7.2-1. Any problems can be reported to Jouk Jansen <joukj@hrem.stm.tudelft.nl> or Martin P.J.

As a special exception, FreeType can also be built with the 'makepp' build tool, available from https://makepp.sourceforge.net. Note, however, that you will need at least version 2.0 and pass the option --norc-substitution to have it work correctly.	whupdup/frame	real/third_party/freetype-2.12.0/docs/MAKEPP	none	gpl-3.0	256
This file describes various problems that have been encountered in compiling, installing and running FreeType 2. Suggestions for additions or other improvements to this file are welcome. ---------------------------------------------------------------------- Running Problems ================ * Some Type 1, Multiple Masters, and CID-keyed PostScript fonts aren't handled correctly. ----- Of course, there might be bugs in FreeType, but some fonts based on the PostScript format can't be handled indeed. The reason is that FreeType doesn't contain a full PostScript interpreter but applies pattern matching instead. In case a font doesn't follow the standard structure of the given font format, FreeType fails. A typical example is Adobe's `Optima' font family which contains extra code to switch between low and high resolution versions of the glyphs. It might be possible to patch FreeType in some situations, though. Please report failing fonts so that we investigate the problem and set up a list of such problematic fonts. * Why do identical FreeType versions render differently on different platforms? ----- Different distributions compile FreeType with different options. The developer version of a distribution's FreeType package, which is needed to compile your program against FreeType, includes the file ftoption.h. Compare each platform's copy of ftoption.h to find the differences. ---------------------------------------------------------------------- Compilation Problems ==================== * I get an `internal compilation error' (ICE) while compiling FreeType 2.2.1 with Intel C++. This has been reported for the following compiler version: Intel(R) C++ Compiler for 32-bit applications, Version 9.0 Build 20050430Z Package ID: W_CC_P_9.0.019 ----- The best solution is to update the compiler to version Intel(R) C++ Compiler for 32-bit applications, Version 9.1 Build 20060323Z Package ID: W_CC_P_9.1.022 or newer.

After saying `make refdoc' or `make refdoc-venv' the `reference/' directory contains the FreeType API reference. You need Python >= 3.5 and pip to make this target. There are two ways to generate the documentation: 1. Using `make refdoc': - Ensure `python' and `pip' are available. - Install pip package `docwriter' with `pip install --user docwriter'. - Make target with `make refdoc'. - This target can be run offline once required packages are installed. 2. Using `make refdoc-venv' (requires internet access): - Ensure `python', `pip' and Python package `virtualenv' are available. - Make target with `make refdoc-venv'. - This may or may not require internet access every time depending on pip and system caching. This also works with Jam: Just type `jam refdoc' in the main directory. Some troubleshooting tips: * Regularly run `pip install --upgrade docwriter' to check for updates which may include bug fixes. * `Docwriter' does not support Python 2. Ensure that Python >= 3.5 is installed and available as `python3'/`python'. * Ensure that `docwriter' is installed in the same Python target that `make refdoc' uses (python3/python). * If none of this works, send a mail to `freetype-devel@nongnu.org' or file an issue at `https://github.com/freetype/docwriter/issues'.	whupdup/frame	real/third_party/freetype-2.12.0/docs/README	none	gpl-3.0	1,323
Here is a list of items that need to be addressed in FreeType 2 --------------------------------------------------------------- * Implement stem3/counter hints properly in the Postscript hinter. * Add CIDCMap support to the CID driver. * Add track kerning support to the PFR driver. * Add kerning (AFM file) support to the CID driver. Here is a list of bugs which should be handled ---------------------------------------------- Other bugs have been registered at the savannah bugzilla of FreeType. * CID driver: Handle the case where a CID font has a top-level font matrix also (see PLRM, 5.11.3, Type 0 CIDFonts). Since CID_FaceInfoRec lacks a font_matrix entry we have to directly apply it to all subfont matrices. * CID driver: Use top-level font matrix entry for setting the upem value, not the entries in the FDarray. If absent, use 1000. ------------------------------------------------------------------------ Copyright (C) 2001-2022 by David Turner, Robert Wilhelm, and Werner Lemberg.

Due to our use of `libtool' to generate and install the FreeType 2 libraries on Unix systems, as well as other historical events, it is generally very difficult to know precisely which release of the font engine is installed on a given system. This file tries to explain why and to document ways to properly detect FreeType on Unix. 1. Version and Release numbers ------------------------------ For each new public release of FreeType 2, there are generally three distinct `version' numbers to consider: * The official FreeType 2 release number, like 2.7.0 or 2.10.2. * The libtool (and Unix) specific version number, like 23.2.17. This is what pkg-config freetype2 --modversion or freetype-config --version returns. * The platform-specific shared object number, used for example when the library is installed as `/usr/lib/libfreetype.so.6.17.2'. The platform-specific number is, unsurprisingly, platform-specific and varies with the operating system you are using (several variants of Linux, FreeBSD, Solaris, etc.). You should thus _never_ use it, even for simple tests. The libtool-specific number does not equal the release number but is tied to it. The release number is available at compile time through the following macros defined in `freetype.h': - FREETYPE_MAJOR: major release number - FREETYPE_MINOR: minor release number - FREETYPE_PATCH: patch release number See below for a small autoconf fragment. The release number is also available at runtime through the `FT_Library_Version' API. 2. History ---------- The following table gives, for all releases since 2.5.0, the corresponding libtool number, as well as the shared object number found on _most_ systems, but not all of them: release libtool so ------------------------------- 2.12.0 24.2.18 6.18.2 2.11.1 24.1.18 6.18.1 2.11.0 24.0.18 6.18.0 2.10.4 23.4.17 6.17.4 2.10.3 23.3.17 6.17.3 2.10.2 23.2.17 6.17.2 2.10.1 23.1.17 6.17.1 2.10.0 23.0.17 6.17.0 2.9.1 22.1.16 6.16.1 2.9.0 22.0.16 6.16.0 2.8.1 21.0.15 6.15.0 2.8.0 20.0.14 6.14.0 2.7.1 19.0.13 6.13.0 2.7.0 18.6.12 6.12.6 2.6.5 18.5.12 6.12.5 2.6.4 18.4.12 6.12.4 2.6.3 18.3.12 6.12.3 2.6.2 18.2.12 6.12.2 2.6.1 18.1.12 6.12.1 2.6.0 18.0.12 6.12.0 2.5.5 17.4.11 6.11.4 2.5.4 17.3.11 6.11.3 2.5.3 17.2.11 6.11.2 2.5.2 17.1.11 6.11.1 2.5.1 17.0.11 6.11.0 2.5.0 16.2.10 6.10.2 3. Autoconf Code Fragment ------------------------- Lars Clausen contributed the following autoconf fragment to check which version of FreeType is installed on a system (now updated to use `pkg-config' instead of `freetype-config'). This one tests for a version that is at least 2.10.2; you should change it to check against other release numbers.

This file contains a list of various font formats. It gives the reference document and whether it is supported in FreeType 2. Table fields ------------ wrapper format The format used to represent the font data. In the table below it is used only if the font format differs. Possible values are SFNT binary PFB binary PS a text header, followed by binary or text data LZW compressed with either `gzip' or `compress' BZ2 compressed with `bzip2'. font format How the font is to be accessed, possibly after converting the file type and wrapper format into a generic form. Bitmap formats are `BDF', `PCF', and one form of `WINFNT'; all others are vector formats. `PS' indicates third-order, `TT' second-order Bézier curves. font type Sub-formats of the font format. `SBIT' and `MACSBIT' are bitmap formats, `MM' and `VAR' support optical axes. `CFF2' supports optical axes also. glyph access If not specified, the glyph access is `standard' to the font format. Values are `CID' for CID-keyed fonts, `SYNTHETIC' for fonts that are modified versions of other fonts by means of a transformation matrix, and `TYPE_0' for PS fonts which are to be accessed in a tree-like structure. FreeType driver The module in the FreeType library which handles the specific font format. A missing entry means that FreeType doesn't support the font format (yet). Notes ----- The SFNT container format also provides `collections' (usually having the file extension `.ttc' or `.otc'). A collection contains multiple font faces that share some tables to avoid redundancy, thus reducing the file size. In FreeType, elements of a collection can be accessed with a proper face index. Both the GX and the OpenType 1.8 variation fonts provide `named instances'. FreeType maps them to face indices (they can also be accessed with the standard MM interface). Other font formats (not using the SFNT wrapper) also provide multiple faces within one file; they are marked with an asterisk (`') in the table below. FreeType can be configured to support Mac files (on older Mac OS versions, a `file' is stored as a data and a resource fork, this is, within two separate data chunks). If a file can't be opened as a font, FreeType then checks whether it is a resource fork, trying to extract the contained font data from either a `POST' or `sfnt' resource. Please send additions and/or corrections to wl@gnu.org or to the FreeType developer's list at freetype-devel@nongnu.org (for subscribers only).

.TH FREETYPE-CONFIG 1 "March 2022" "FreeType 2.12.0" . . .SH NAME . freetype-config \- Get information about a libfreetype installation . . .SH SYNOPSIS . .B freetype-config .RI [ options ] . . .SH DESCRIPTION . .B freetype-config returns information needed for compiling and linking programs with the FreeType library, such as linker flags and compilation parameters. . Alternatively, it can be used to query information about the FreeType library version installed on the system, such as the installation (directory path) prefix or the FreeType version number. . .PP If .BR pkg-config (1) is found in the path, .B freetype-config acts as a wrapper for .BR pkg-config . . .PP This program is part of the FreeType package. . . .SH OPTIONS . There are two types of options: output/display selection options, and path override options. . . .SS Output selection options . Only one of the output selection options should be given at each program invocation. . .TP .B \-\-prefix Return the prefix value of the installed FreeType library (the default prefix will be `/usr' in most cases for distribution-installed packages). . .TP .B \-\-exec-prefix Return the executable prefix value of the installed FreeType library (will often be the same as the prefix value). . .TP .B \-\-ftversion Return the FreeType version number, directly derived from file `freetype.h'. . .TP .B \-\-version Return the `libtool version' of the FreeType library. . .TP .B \-\-libtool Return the library name for linking with libtool. . .TP .B \-\-libs Return compiler flags for linking with the installed FreeType library. . .TP .B \-\-cflags Return compiler flags for compiling against the installed FreeType library. . .TP .B \-\-static Make command line options display flags for static linking. . .TP .B \-\-help Show help and exit. . . .SS Path override options . These affect any selected output option, except the libtool version returned by .BR \-\-version . . .TP .BI \-\-prefix= PREFIX Override .B \-\-prefix value with .IR PREFIX . . This also sets .BI \-\-exec-prefix= PREFIX if option .B \-\-exec-prefix is not explicitly given. . .TP .BI \-\-exec-prefix= EPREFIX Override .B \-\-exec-prefix value with .IR EPREFIX . . . .SH BUGS In case the libraries FreeType links to are located in non-standard directories, and .BR pkg-config (1) is not available, the output from option .B \-\-libs might be incomplete. . It is thus recommended to use the .BR pkg-config (1) interface instead, which is able to correctly resolve all dependencies. . .PP Setting .B \-\-exec-prefix (either explicitly or implicitly) might return incorrect results if combined with option .BR \-\-static . . The same problem can occur if you set the .B SYSROOT environment variable. . . .SH AUTHOR .

It previously didn't accept more than one argument correctly. For example, when typing: ./configure --disable-shared --disable-nls the `--disable-nls' was incorrectly sent to the `make' program. 2002-01-29 Werner Lemberg <wl@gnu.org> * README.UNX: Fix typo. * builds/unix/install.mk (uninstall): Fix library name for libtool. 2002-01-28 Francesco Zappa Nardelli <Francesco.Zappa.Nardelli@ens.fr> * src/pcf/pcfdriver.c (PCF_Done_Face): Fix incorrect destruction of the face object (face->toc.tables, face->root.family_name, face->root.available_size, face->charset_encoding, face->charset_registry are now freed). Thanks to Niels Moseley. 2002-01-28 Roberto Alameda <ojancano@geekmail.de> * src/type1/t1load.c (parse_encoding): Set `loader->num_chars'. 2002-01-28 Werner Lemberg <wl@gnu.org> * src/type1/t1load.c (parse_subrs, parse_charstrings): Use copy of `base' string for decrypting to not modify the original data.

This results in a 5-7% speedup in rendering speed. 2002-01-08 David Turner <david@freetype.org> Added some wrapper scripts to make the installation more Unix-friendly. * configure, install: New files. * INSTALL, README.UNX: Updated installation documentation to use the new 'configure' and 'install' scripts. 2002-01-07 David Turner <david@freetype.org> * Version 2.0.6 released. ========================= * docs/BUGS, docs/CHANGES: Updating documentation for 2.0.6 release. * src/tools/docmaker.py: Fixed HTML quoting in sources. (html_format): Replaced with ... (html_quote): New function. (html_quote0): New function. (DocCode::dump_html): Small improvement. (DocParagraph::dump, DocBlock::html): Use html_quote0 and html_quote. * include/freetype/config/ftoption.h: Setting default options for a release build (debugging off, bytecode interpreter off). * src/base/ftobjs.c, src/base/ftoutln.c, src/cache/ftccmap.c, src/cff/cffload.c, src/cff/cffobjs.c, src/pshinter/pshalgo2.c, src/sfnt/ttload.c, src/sfnt/ttsbit.c: Removing small compiler warnings (in pedantic compilation modes). 2002-01-05 David Turner <david@freetype.org> * src/autohint/ahhint.c (ah_align_linked_edge): Modified computation of auto-hinted stem widths; this avoids color fringes in `ClearType-like' rendering. * src/truetype/ttgload.c (TT_Load_Glyph_Header, TT_Load_Simple_Glyph, TT_Load_Composite_Glyph, load_truetype_glyph): Modified the TrueType loader to make it more paranoid; this avoids nasty buffer overflows in the case of invalid glyph data (as encountered in the output of some buggy font converters). 2002-01-04 David Turner <david@freetype.org> * README.UNX: Added special README file for Unix users. * builds/unix/ftsystem.c (FT_New_Stream): Fixed typo. * src/base/ftobjs.c: Added #include FT_OUTLINE_H to get rid of compiler warnings. * src/base/ftoutln.c (FT_Outline_Check): Remove compiler warning. 2002-01-03 Werner Lemberg <wl@gnu.org> * src/type1/t1objs.c (T1_Face_Init): Add cast to avoid compiler warning. 2002-01-03 Keith Packard <keithp@keithp.com> * builds/unix/ftsystem.c (FT_New_Stream): Added a fix to ensure that all FreeType input streams are closed in child processes of a `fork' on Unix systems. This is important to avoid (potential) access control issues. 2002-01-03 David Turner <david@freetype.org> * src/type1/t1objs.c (T1_Face_Init): Fixed a bug that crashed the library when dealing with certain weird fonts like `Stalingrad', in `sadn.pfb' (this font has no full font name entry). * src/base/ftoutln.c, include/freetype/ftoutln.h (FT_Outline_Check): New function to check the consistency of outline data. * src/base/ftobjs.c (FT_Load_Glyph): Use `FT_Outline_Check' to ensure that loaded glyphs are valid. This allows certain fonts like `tt1095m_.ttf' to be loaded even though it appears they contain really funky glyphs. There still is a bug there, though. * src/truetype/ttgload.c (load_truetype_glyph): Fix error condition. 2001-12-30 David Turner <david@freetype.org> * src/autohint/ahhint.c (ah_hinter_load): Fix advance width computation of auto-hinted glyphs. This noticeably improves the spacing of letters in KDE and Gnome. 2001-12-25 Antoine Leca <Antoine-Freetype@Leca-Marti.org> * builds/dos/detect.mk: Correcting the order for Borland compilers: 16-bit bcc was never selected, always overridden by 32-bit bcc32. 2001-12-22 Francesco Zappa Nardelli <Francesco.Zappa.Nardelli@ens.fr> * src/pcf/pcfread.c (pcf_load_font): Handle property `POINT_SIZE' and fix incorrect computation of `available_sizes'. 2001-12-22 David Turner <david@freetype.org> * src/autohint/ahhint.c (ah_hinter_load): Auto-hinted glyphs had an incorrect glyph advance in the case of mono-width fonts (like Courier, Andale Mono, and others). 2001-12-22 Detlef Würkner <TetiSoft@apg.lahn.de> * builds/amiga/: Adaptations to latest changes. Support added for MorphOS. 2001-12-22 Werner Lemberg <wl@gnu.org> src/pshinter/pshrec.c (FT_COMPONENT): Redefine to `trace_pshrec'. (ps_mask_table_merge, ps_hints_open, ps_hints_stem, ps_hints_t1stem3, ps_hints_t2mask, ps_hints_t2counter): Fix FT_ERROR messages. * src/pshinter/pshalgo1.c (FT_COMPONENT): Define as `trace_pshalgo1'. * src/pshinter/pshalgo2.c (FT_COMPONENT): Define as `trace_pshalgo2'. * include/freetype/internal/ftdebug.h (FT_Trace): Updated. * docs/modules.txt: New file. 2001-12-21 David Turner <david@freetype.org> * src/pshinter/pshrec.c (ps_hints_t2mask, ps_hints_t2counter): Ignore invalid `hintmask' and `cntrmask' operators (instead of returning an error). Glyph 2028 of the CFF font `MSung-Light-Acro' couldn't be rendered otherwise (it seems its charstring is buggy, though this requires more analysis). (FT_COMPONENT): Define. * src/cff/cffgload.c (CFF_Parse_CharStrings), src/psaux/t1decode.c (T1_Decoder_Parse_Charstrings), src/pshinter/pshalgo2.c (), Fixed a bug where the X and Y axis where inverted in the postscript hinter. This caused problem when displaying on non-square surfaces. src/pshinter/pshalgo2.c: s/vertical/dimension/. * src/pshinter/pshglob.c (psh_globals_new): Replaced a floating point constant with a fixed-float equivalent. For some reasons not all compilers are capable of directly computing a floating pointer constant casted to FT_Fixed, and will link a math library instead. 2001-12-20 Werner Lemberg <wl@gnu.org> * src/cache/ftccache.c (ftc_node_destroy, ftc_cache_lookup): Fix tracing strings. * src/cache/ftccmap.c (ftc_cmap_family_init): Ditto. * src/cache/ftcmanag.c (ftc_family_table_alloc, ftc_family_table_free, FTC_Manager_Check): Ditto. * src/cache/ftcsbits.c (ftc_sbit_node_load): Ditto. * src/base/ftobjs.c (FT_Done_Library): Remove compiler warning. 2001-12-20 David Turner <david@freetype.org> Added PostScript hinter support to the CFF and CID drivers. * include/freetype/internal/cfftypes.h (CFF_Font): New member `pshinter'. * src/cff/cffload.c (CFF_Get_Standard_Encoding): New function. * src/cff/cffload.h: Updated. * src/cff/cffgload.c (CFF_Init_Builder): Renamed to ... (CFF_Builder_Init): This. Added new argument `hinting'. (CFF_Done_Builder): Renamed to ... (CFF_Builder_Done): This. (CFF_Init_Decoder): Added new argument `hinting'. (CFF_Parse_CharStrings): Implement vstem support. (CFF_Load_Glyph): Updated. Add hinting support. (cff_lookup_glyph_by_stdcharcode): Use CFF_Get_Standard_Encoding(). (cff_argument_counts): Updated. * src/cff/cffgload.h: Updated. * src/cff/cffobjs.c: Include FT_INTERNAL_POSTSCRIPT_HINTS_H. (CFF_Size_Get_Globals_Funcs, CFF_Size_Done, CFF_Size_Init, CFF_Size_Reset, CFF_GlyphSlot_Done, CFF_GlyphSlot_Init): New functions. (CFF_Init_Face): Renamed to ... (CFF_Face_Init): This. Add hinter support. (CFF_Done_Face): Renamed to ... (CFF_Face_Done): This. (CFF_Init_Driver): Renamed to ... (CFF_Driver_Init): This. (CFF_Done_Driver): Renamed to ... (CFF_Driver_Done): This. * src/cff/cffobjs.h: Updated. * src/cff/cffdrivr.c (cff_driver_class): Updated. * include/freetype/internal/t1types.h (CID_FaceRec): New member `pshinter'. * src/cid/cidgload.c (CID_Load_Glyph): Add hinter support. * src/cid/cidobjs.c: Include FT_INTERNAL_POSTSCRIPT_HINTS_H. (CID_GlyphSlot_Done, CID_GlyphSlot_Init, CID_Size_Get_Globals_Funcs, CID_Size_Done, CID_Size_Init, CID_Size_Reset): New functions. (CID_Done_Face): Renamed to ... (CID_Face_Done): This. (CID_Init_Face): Renamed to ... (CID_Face_Init): This. Add hinting support. (CID_Init_Driver): Renamed to ... (CID_Driver_Init): This. (CID_Done_Driver): Renamed to ...

This reverts change 2001-08-08. * docs/CHANGES: Updated for 2.0.6 release. * docs/TODO: Added `stem3 and counter hints support' to the TODO list for the Postscript hinter. * docs/BUGS: Closed the AUTOHINT-NO-SBITS bug. 2001-12-19 David Turner <david@freetype.org> * include/freetype/cache/ftcache.h: Added comments to indicate that some of the exported functions should only be used by applications that need to implement custom cache types. * src/truetype/ttgload.c (cur_to_org, org_to_cur): Fixed a nasty bug that prevented composites from loading correctly, due to missing parentheses around macro parameters. * src/sfnt/sfobjs.c (SFNT_Load_Face): Make the `post' and `name' tables optional to load PCL fonts properly. * src/truetype/ttgload.c (TT_Load_Glyph), src/base/ftobjs.c (FT_Load_Glyph), include/freetype/freetype.h (FT_LOAD_SBITS_ONLY): `Fixed' the bug that prevented embedded bitmaps to be loaded when the auto-hinter is used. This actually is a hack but will be enough until the internal re-design scheduled for FreeType 2.1. * src/raster/ftrend1.c (ft_raster1_render): Fixed a nasty outline shifting bug in the monochrome renderer. * README: Updated version numbers to 2.0.6. 2001-12-17 Werner Lemberg <wl@gnu.org> * src/truetype/ttgload.c (load_truetype_glyph): Fix test for invalid glyph header. 2001-12-15 Werner Lemberg <wl@gnu.org> * src/base/ftglyph.c (FT_Glyph_To_Bitmap): Remove compiler warning. * include/freetype/ftcache.h (FTC_Node_Unref): Removed.

We need to install it in $(prefix)/share/aclocal/freetype2.m4 but I didn't modify builds/unix/install.mk yet. * INSTALL: Updated the instructions to build shared libraries with Jam. They were simply wrong. * src/base/fttrigon.c (FT_Cos): Fixed a small bug that caused slightly improper results for `FT_Cos' and `FT_Sin' (example: FT_Sin(0) == -1!). 2001-12-11 Detlef Würkner <TetiSoft@apg.lahn.de> * include/freetype/internal/ftstream.h (GET_LongLE, GET_ULongLE): Fixed incorrect argument types. 2001-12-10 Francesco Zappa Nardelli <Francesco.Zappa.Nardelli@ens.fr> * src/pcf/pcfdriver.c (PCF_Init_Face): Allow Xft to use PCF fonts by setting the `face->metrics.max_advance' correctly. 2001-12-07 David Turner <david@freetype.org> * include/freetype/cache/ftccmap.h, src/cache/ftccmap.c: Added new charmap cache. * src/cache/ftcache.c: Updated. * src/autohint/ahhint.c (ah_hinter_hint_edges): s/UNUSED/FT_UNUSED/. 2001-12-06 Leonard Rosenthol <leonardr@lazerware.com> Added support for reading .dfont files on Mac OS X. Also added a new routine which looks up a given font by name in the Mac OS and returns the disk file where it resides. * src/base/ftmac.c: Include <Files.h> and <TextUtils.h>. (is_dfont): New auxiliary function. (FT_New_Face_From_dfont): New function. (FT_GetFile_From_Mac_Name): New exported function.

Comment out use of `origin'. * src/smooth/ftsmooth.c (ft_smooth_render): Fixed a nasty hidden bug where outline shifting wasn't correctly undone after bitmap rasterization. This created problems with certain glyphs (like '"' of certain fonts) and the cache system. * src/pshinter/pshalgo1.c (psh1_hint_table_init): Fix typo. * src/pshinter/pshalgo2.c (psh2_hint_table_init): Fix typo. (ps2_hints_apply): Small fix. 2001-12-05 David Turner <david@freetype.org> * src/pshinter/pshalgo2.c (psh2_hint_table_init), src/pshinter/pshalgo1.c (psh1_hint_table_init): Removed compiler warnings. * include/freetype/ftcache.h, include/freetype/cache/, src/cache/: Yet another massive rewrite of the caching sub-system in order to both increase performance and allow simpler cache sub-classing. As an example, the code for the image and sbit caches is now much simpler. I still need to update the documentation in www/freetype2/docs/cache.html to reflect the new design though. * include/freetype/config/ftheader.h (FT_CACHE_CHARMAP_H): New macro. (FT_CACHE_INTERNAL_CACHE_H): Updated. 2001-12-05 David Krause <freetype@davidkrause.com> * docs/license.txt: s/X Windows/X Window System/. 2001-12-04 Werner Lemberg <wl@gnu.org> * src/raster/ftraster.c: Fix definition condition of MEM_Set(). * src/smooth/ftgrays.c (M_Y): Change value to 192. * src/base/ftdbgmem.c (ft_mem_table_destroy): Fix printf() parameter.

Also added comments about the meaning of bit 57 of the `OS/2' table (TT_UCR_SURROGATES) which (with OpenType v.1.3) now means `there is a character beyond 0xFFFF in this font'. Thanks to Detlef Würkner <TetiSoft@apg.lahn.de> for noticing this. 2001-11-20 David Turner <david@freetype.org> * src/pshinter/{pshalgo2.c, pshalgo1.c}: Fixed stupid bug in sorting routine that created nasty alignment artefacts. * src/pshinter/pshrec.c, tests/gview.c: Debugging updates. * src/smooth/ftgrays.c: De-activated experimental gamma support. Apparently, `optimal' gamma tables depend on the monitor type, resolution and general karma, so it's better to compute them outside of the rasterizer itself. (gray_convert_glyph): Use `volatile' keyword. 2001-10-29 David Turner <david@freetype.org> Adding experimental `gamma' support. This produces smoother glyphs at small sizes for very little cost. * src/smooth/ftgrays.c (grays_init_gamma): New function. (gray_raster_new): Use it. Various fixes to the auto-hinter. They merely improve the output of sans-serif fonts. Note that there are still problems with serifed fonts and composites (accented characters). * src/autohint/ahglyph.c (ah_outline_load, ah_outline_link_segments): Implement it. Fix typos. (ah_outline_save, ah_outline_compute_segments): Fix typos. * src/autohint/ahhint.c (ah_align_serif_edge): New argument `vertical'. Implement improvement.

(AH_Hinter): Remove `disable_horz_edges' and `disable_vert_edges' (making them global as `ah_debug_disable_horz' and `ah_debug_disable_vert'). Fix typos. * tests/gview.c: Updated the debugging glyph viewer to show the hints generated by the `autohint' module. 2001-10-27 David Turner <david@freetype.org> * src/cache/ftcchunk.c (ftc_chunk_cache_lookup): Fixed a bug that considerably lowered the performance of the abstract chunk cache. 2001-10-26 David Turner <david@freetype.org> * include/freetype/ftcache.h, include/freetype/cache/.h, src/cache/.c: Major re-design of the cache sub-system to provide better performance as well as an `Acquire'/`Release' API. Seems to work well here, but probably needs a bit more testing. 2001-10-26 Leonard Rosenthol <leonardr@lazerware.com> * builds/mac/README: Updated to reflect my taking over the project and that is now being actively maintained. * src/base/ftmac.c (parse_fond): Applied patches from Paul Miller <paulm@profoundeffects.com> to support loading a face other than the first from a FOND resource. (FT_New_Face_From_FOND): Updated. 2001-10-25 Leonard Rosenthol <leonardr@lazerware.com> * builds/mac/ftlib.prj: Update of CodeWarrior project file for Mac OS for latest version (7) of CWPro and for recent changes to the FT source tree. 2001-10-25 David Turner <david@freetype.org> * include/freetype/config/ftoption.h: Updated comments to explain precisely how to use project-specific macro definitions without modifying this file manually. (FT_CONFIG_FORCE_INT64): Define. (FT_DEBUG_MEMORY): New macro. 2001-10-24 Tom Kacvinsky <tkacvins@freetype.org> * builds/unix/ftsystem.c (FT_New_Memory): Added a missing `{'. 2001-10-23 David Turner <david@freetype.org> * include/freetype/internal/ftmemory.h, src/base/ftdbgmem.c: Improvements to the memory debugger to report more information in case of errors. Also, some allocations that occurred through REALLOC couldn't be previously caught correctly. * src/autohint/ahglyph.c (ah_outline_compute_segments, ah_outline_compute_edges), src/raster/ftraster.c (ft_black_new), src/smooth/ftgrays.c (gray_render_span, gray_raster_new): Replaced liberal uses of memset() by the MEM_Set() macro. 2001-10-23 David Turner <david@freetype.org> * src/raster/ftraster.c (Update): Removed to be inlined in ... (Sort): Updated. 2001-10-22 David Turner <david@freetype.org> * builds/unix/ftsystem.c (FT_New_Memory, FT_Done_Memory), builds/vms/ftsystem.c (FT_New_Memory, FT_Done_Memory), builds/amiga/ftsystem.c (FT_New_Memory, FT_Done_Memory), src/base/ftdbgmem.c: Updated the memory debugger and platform-specific implementations of `ftsystem' in order to be able to debug memory allocations on Unix, VMS and Amiga too! * src/pshinter/pshalgo2.c (psh2_hint_table_record_mask): Removed some bogus warnings. * include/freetype/internal/ftmemory.h, src/base/ftdbgmem.c: Modified the debugging memory manager to report the location (source file name + line number) where leaked memory blocks are allocated in the source file. * src/base/ftdbgmem.c: New debugging memory manager. You must define the FT_DEBUG_MEMORY macro in `ftoption.h' to enable it. It will record every memory block allocated and report simple errors like memory leaks and double deletes. * src/base/Jamfile: Include ftdbgmem. * src/base/rules.mk: Ditto. * src/base/ftbase.c: Include ftdbgmem.c. * include/freetype/config/ftoption.h: Added the FT_DEBUG_MEMORY macro definition. * src/base/ftsystem.c (FT_New_Memory, FT_Done_Memory): Modified the base component to use the debugging memory manager when the macro FT_DEBUG_MEMORY is defined. 2001-10-21 Tom Kacvinsky <tkacvins@freetype.org> * src/cff/cffload.c (CFF_Done_Font): Free subfonts array only if we are working with a CID keyed CFF font. Otherwise, a variable that was never allocated memory might freed. This is a correction to the previous patch for freeing subfonts. 2001-10-21 Tom Kacvinsky <tkacvins@freetype.org> * src/cff/cffload.c (CFF_Done_Font): Free the subfonts array to avoid a memory leak. 2001-10-21 David Turner <david@freetype.org> * src/pshinter/pshalgo2.c, src/pshinter/pshalgo1.c, src/pshinter/pshglob.c: Removing compiler warnings in pedantic modes (in multi-object compilation mode, mainly). 2001-10-20 Tom Kacvinsky <tkacvins@freetype.org> * src/type1/t1load.c (parse_encoding): Add a test to make sure that custom encodings (i.e., neither StandardEncoding nor ExpertEncoding) are not loaded twice when the Type 1 font is synthetic. * src/type1/t1load.c (parse_font_name, parse_subrs): Added a test for when loading synthetic fonts to make sure that the font name and subroutines are not loaded twice. This is to remove a memory leak that occurred because the original memory blocks for these objects were not deallocated when the objects were parsed the second time. 2001-10-19 David Turner <david@freetype.org> * src/smooth/ftgrays.c, src/pshinter/pshglob.h, src/pshinter/pshrec.c, src/pshinter/pshalgo2.c: Getting rid of compiler warnings. * src/pshinter/module.mk, src/pshinter/rules.mk: Adding control files to build the PostScript hinter with the `old' build system. 2001-10-19 Jacob Jansen <joukj@hrem.stm.tudelft.nl> * descrip.mms, src/pshinter/descrip.mms: Updates to the VMS build files. 2001-10-18 David Turner <david@freetype.org> * src/psnames/pstables.h, src/tools/glnames.py: Rewrote the `glnames.py' script used to generate the `pstables.h' header file. The old one contained a serious bug that made FreeType return incorrect glyph names for certain glyphs. * src/truetype/ttdriver.c (Set_Char_Sizes): Changing computation of pixel size from character size to use rounding. This is an experiment to see whether this gives values similar to Windows for scaled ascent/descent/etc. * src/base/ftcalc.c (FT_Div64by32): Changed the implementation slightly since the original code was mis-compiled on Mac machines using the MPW C compiler. * src/base/ftobjs.c (FT_Realloc): When a memory block was grown through FT_Realloc(), the new bytes were not set to 0, which created some strange bugs in the PostScript hinter. (destroy_face): Don't deallocate unconditionally. * src/cid/cidgload.c (CID_Compute_Max_Advance, CID_Load_Glyph): Adding support to new PostScript hinter. * include/freetype/internal/psglobal.h, include/freetype/internal/pshints.h, include/freetype/config/ftmodule.h, src/pshinter/Jamfile, src/pshinter/pshalgo.h, src/pshinter/pshalgo1.h, src/pshinter/pshalgo1.c, src/pshinter/pshalgo2.h, src/pshinter/pshalgo2.c, src/pshinter/pshglob.h, src/pshinter/pshglob.c, src/pshinter/pshinter.c, src/pshinter/pshmod.c, src/pshinter/pshmod.h, src/pshinter/pshrec.c, src/pshinter/pshrec.h: Adding new PostScript hinter module. * include/freetype/internal/ftobjs.h, include/freetype/internal/internal.h, include/freetype/internal/psaux.h, include/freetype/internal/t1types.h, src/psaux/psobjs.c, src/psaux/psobjs.h, src/psaux/t1decode.h, src/psaux/t1decode.c, src/type1/t1driver.c, src/type1/t1gload.c, src/type1/t1objs.c, src/type1/t1objs.h: Updates to use the new PostScript hinter. * tests/Jamfile, tests/gview.c: Adding a new glyph hinting viewer/debugger to the source tree. Note that you will _not_ be able to compile it since it depends on an unavailable graphics library named `Nirvana' to render vector images. 2001-10-17 David Turner <david@freetype.org> * Version 2.0.5 released. ========================= * include/freetype/freetype.h, include/internal/ftobjs.h, src/base/ftobjs.c, src/type1/t1driver.c: Adding a new function named 'FT_Get_Postscript_Name' to retrieve the PostScript name of a given font.

This resulted in the unavailability of certain glyphs like `Cacute', `cacute' and `lslash' in Unicode charmaps, even if these were present in the font (causing problems for Polish users). * src/tools/glnames.py (mac_standard_names): Fixed. (t1_standard_strings): Some fixes and renamed to ... (sid_standard_names): This. (t1_expert_encoding): Fixed. (the_adobe_glyph_list): Renamed to ... (adobe_glyph_names): This.

Function names are now all uniformly prefixed with `gray_'. * src/smooth/ftgrays.c: Include <setjmp.h>. (ErrRaster_MemoryOverflow): New macro. (TArea): New type to store area values in each cell (using `int' was too small on 16-bit systems). <limits.h> is included to properly get the needed data type. (TCell, TRaster): Use it. (TRaster): New element `jump_buffer'. (gray_compute_cbox): Use `RAS_ARG' as the only parameter and get `outline' from it. (gray_record_cell): Use longjmp().

If you simply say `x' or `(Bar)x', then the C compiler would warn you that type casting incompatible pointer types breaks strict-aliasing. The solution is to cast to `(void)' instead which is the generic pointer type, so the compiler knows that it should make no strict-aliasing assumption on `x'. But the problem with `(void)x' is that seems like in C++, unlike C, `void' is not a generic pointer type and assigning `void' to `Bar' without a cast causes an error. The solution is to cast to `Bar' too, with `(Bar)(void)x' as the result -- this is what the patch does. include/freetype/cache/ftccache.h (FTC_CACHE_LOOKUP_CMP), include/freetype/cache/ftcmru.h (FTC_MRULIST_LOOKUP_CMP): Remove cast on lvalue, use a temporary pointer instead.

The idea is to avoid loading and decoding tables in the heap, and instead access the raw data whenever possible (i.e., when it doesn't compromise performance). This has several benefits: For example, opening vera.ttf now uses just a small amount of memory (even when the FT_Library footprint is accounted for), until you start loading glyphs. Even then, you save at least 20KB compared to the non-optimized case. Performance of various operations, including open and close, has also been dramatically improved. More optimizations to come, especially for the auto-hinter. * include/freetype/internal/sfnt.h (TT_Face_GetKerningFunc): New function type.

Don't define `hdmx', `num_kern_pairs', `kern_table_index', `kern_pairs' if FT_OPTIMIZE_MEMORY is set. * src/base/ftdbgmem.c (ft_mem_table_set): Don't shadow variable. Fix compiler warning. * src/cff/cffdrivr.c (Get_Kerning): Renamed to... (cff_get_kerning): This. Simplify.

Update all callers. * src/truetype/ttgload.h: Updated. 2005-02-22 David Turner <david@freetype.org> * src/base/ftdbgmem.c: Partly rewritten. Added the ability to list all allocation sites in the memory debugger. Also a new function FT_DumpMemory() was added. It is only available in builds with FT_DEBUG_MEMORY defined, and you must declare it in your own code to use it, i.e., with something like: extern void FT_DumpMemory( FT_Memory ); ... FT_DumpMemory( memory ); * include/freetype/config/ftoption.h (TT_CONFIG_OPTION_BYTECODE_INTERPRETER): Comment out definition -- again.

Unused. 2004-07-12 David Turner <david@freetype.org> * src/base/ftstroke.c (ft_stroke_border_close): Add second parameter to indicate reversion of points. Update all callers. (ft_stroke_border_reverse): Fix initialization of `point1' and `tag1'. * src/cache/ftcsbits.c (ftc_snode_load): Fixing advance computation for transformed glyphs. 2004-07-11 David Turner <david@freetype.org> Fix bugs that prevented the stroker to correctly generate stroked paths from closed paths, i.e., nearly all glyphs in vectorial fonts.

Reported by Dirck Blaskey. 2004-06-24 David Turner <david@freetype.org> * Version 2.1.9 released. ========================= * src/truetype/ttgload.c, src/truetype/ttxgvar.c: Removing compiler warnings. 2004-06-23 Werner Lemberg <wl@gnu.org> * include/freetype/internal/ftmemory.h [FT_DEBUG_MEMORY]: Declare FT_QAlloc_Debug and FT_QRealloc_Debug. * src/base/ftutil.c (FT_QAlloc): Fix error and debug messages. (FT_QRealloc): Call FT_QAlloc if original pointer is NULL. Fix error message. 2004-06-23 David Turner <david@freetype.org> * include/freetype/internal/ftmemory.h, src/base/ftutil.c (FT_QAlloc, FT_QRealloc), src/base/ftdbgmem.c (FT_QAlloc_Debug, FT_QRealloc_Debug): New functions that perform allocation without zero-ing out the corresponding blocks. * include/freetype/internal/ftmemory.h (FT_MEM_QALLOC, FT_MEM_QREALLOC, FT_MEM_QNEW, FT_MEM_QNEW_ARRAY, FT_MEM_QRENEW_ARRAY, FT_QALLOC, FT_QREALLOC, FT_QNEW, FT_QNEW_ARRAY, FT_QRENEW_ARRAY): New macros. * src/base/ftstream.c (FT_Stream_EnterFrame): Use FT_QALLOC. * src/gzip/ftgzip.c (FT_Stream_OpenGzip): Use FT_QNEW_ARRAY. * src/sfnt/sfobjs.c (tt_face_get_name): Use FT_QNEW_ARRAY. * src/sfnt/ttload.c (tt_face_load_directory, tt_face_load_metrics, tt_face_load_gasp): Use FT_QNEW_ARRAY.

This dramatically improves the performance of face open/close operations. For example, putting the TrueType driver first in the list results in a 5x speedup when opening `Vera.ttf'. The very problem is that both the PCF and BDF drivers do a lot more than necessary to detect that they cannot handle a font file. 2004-06-22 Werner Lemberg <wl@gnu.org> * src/pcf/pcfread.c (pcf_read_TOC, pcf_get_properties, pcf_get_metrics, pcf_get_bitmaps, pcf_get_encodings): Improve debugging messages. * src/pcf/pcfdrivr.c (FT_COMPONENT): Move up.

The output now seems to be 100% equivalent to the auto-hinter, while being about 2% faster (which proves that script-specific algorithm selection isn't a performance problem). To test it, change `autohint' to `autofit' in <freetype/config/ftmodule.h> and recompile.

(T1_Open_Face): Improve an error message. 2004-02-01 Werner Lemberg <wl@gnu.org> * src/type1/t1load.c (parse_charstrings): Exit immediately if there are no elements in /CharStrings. This is needed for fonts like Optima-Oblique which not only define /CharStrings but access it also. 2004-02-01 David Turner <david@freetype.org> * src/sfnt/Jamfile: Removing `ttcmap' from the list of sources. * include/freetype/cache/ftccache.h (FTC_CACHE_LOOKUP_CMP) <FTC_INLINE>: Provide macro version which doesn't use inline code. * include/freetype/cache/ftcglyph.h (FTC_GCACHE_LOOKUP_CMP) <FTC_INLINE>: Ditto.

At least one font (app850.fon from WinME) contains different FNT charmaps for its subfonts. Consequently, the previous design of having multiple bitmap strikes in a single font face fails since we have only one charmap per face. * include/freetype/internal/fnttypes.h (FNT_Size_Rec): Removed. (FNT_FaceRec): Remove `num_fonts' field and replace `fonts' with `font'. * src/base/ftwinfnt.c (FT_Get_WinFNT_Header): Updated. * src/winfonts/winfnt.c (fnt_font_load): Don't set pixel_width equal to pixel_height.

(FNT_Size_Set_Pixels): To find a strike, first check pixel_height only, then try to find a better hit by comparing pixel_width also. Without this fix it isn't possible to access all strikes. Also compute metrics.max_advance to be in sync with other bitmap drivers. * src/base/ftobjs.c (FT_Set_Char_Size): Remove redundant code. (FT_Set_Pixel_Sizes): Assign value to `metrics' after validation of arguments. 2003-06-20 Werner Lemberg <wl@gnu.org> Synchronize computation of height and width for bitmap strikes. The `width' field in the FT_Bitmap_Size structure is now only useful to enumerate different strikes. The `max_advance' field of the FT_Size_Metrics structure should be used to get the (maximum) width of a strike. * src/bdf/bdfdrivr.c (BDF_Face_Init): Don't use AVERAGE_WIDTH for computing `available_sizes->width' but make it always equal to `available_sizes->height'. * src/pcf/pcfread.c (pcf_load_font): Don't use RESOLUTION_X for computing `available_sizes->width' but make it always equal to `available_sizes->height'. * src/truetype/ttdriver.c (Set_Pixel_Sizes): Pass only single argument to function. * src/psnames/psmodule.c (ps_unicode_value): Handle `.' after `uniXXXX' and `uXXXX[X[X]]'. 2003-06-19 Werner Lemberg <wl@gnu.org> * src/bdf/bdfdrivr.c: s/FT_Err_/BDF_Err/. * src/cache/ftccache.c, src/cache/ftcsbits.c, src/cache/ftlru.c: s/FT_Err_/FTC_Err_/. * src/cff/cffcmap.c: s/FT_Err_/CFF_Err_/. * src/pcf/pcfdrivr.c: s/FT_Err_/PCF_Err_/. * src/psaux/t1cmap.c: Include psauxerr.h. s/FT_Err_/PSaux_Err_/. * src/pshinter/pshnterr.h: New file. * src/pshinter/rules.mk: Updated. * src/pshinter/pshalgo.c, src/pshinter/pshrec.c: Include pshnterr.h. s/FT_Err_/PSH_Err_/. * src/pfr/pfrdrivr.c, src/pfr/pfrobjs.c, src/pfr/pfrsbit.c: s/FT_Err_/PFR_Err_/. * src/sfnt/sfdriver.c, src/sfnt/sfobjs.c, src/sfnt/ttcmap0.c, src/sfnt/ttload.c: s/FT_Err_/SFNT_Err_/. * src/truetype/ttgload.c: s/FT_Err_/TT_Err_/. * src/gzip/ftgzip.c: Load FT_MODULE_ERRORS_H and define FT_ERR_PREFIX and FT_ERR_BASE. s/FT_Err_/Gzip_Err_/. 2003-06-19 Dirck Blaskey <listtarget@danbala.com> * src/cff/cffload (cff_encoding_load): `nleft' must be FT_UInt, otherwise adding 1 might wrap the result. 2003-06-18 Werner Lemberg <wl@gnu.org> * src/psnames/psmodule.c (ps_unicode_value): Add support to recognize `uXXXX[X[X]]' glyph names.

In all makefiles `/' is used as the path separator. The conversion to the real path separators is done as late as possible using $(subst ...). . $(HOSTSEP) no longer exists. Now, $(SEP) gives the path separator for the operating system, and the new $(COMPILER_SEP) the path separator for the compiler tools. . $(BUILD) has been renamed to $(BUILD_DIR). In general, all directory variables end with `_DIR'. The variants ending in `_' (like `BASE_' have been removed). The following ChangeLog entries only describe changes which are not related to the redesign. * builds/beos/beos-def.mk (BUILD_DIR): Fix typo. * builds/compiler/watcom.mk (LINK_LIBRARY): Fix linker call to avoid overlong arguments as suggested by J.

There exist fonts (containing e.g. form drawing characters) which intentionally have a zero line gap value. * src/truetype/ttinterp.c (Free_Project, CUR_Func_freeProj): Removed. Unused. Updated all callers. 2003-06-02 Werner Lemberg <wl@gnu.org> * src/cff/cffobjs.c (cff_face_init): Use symbolic names for Adobe specific encoding IDs (there was a wrong EID value for custom encoding). * src/cff/cffcmap.h (CFF_CMapStdRec): Remove `count'. * src/cff/cffcmap.c (cff_cmap_encoding_init, cff_cmap_encoding_done): Updated.

Updated all callers. * src/bdf/bdfdrivr.c (BDF_Face_Init): Set pixel width and height similar to the PCF driver. * src/bdf/bdf.h (_hashnode): Use `const' for `key'. Updated. * src/gzip/ftgzip.c: C++ doesn't like that the array `inflate_mask' is declared twice. It is perhaps better to modify the zlib source files directly instead of this hack. (zcalloc, zfree, ft_gzip_stream_close, ft_gzip_stream_io): Add casts to make build with g++ successful. 2003-04-24 Manish Singh <yosh@gimp.org> * src/cid/cidobjs.c (cid_face_init), src/type1/t1objs.c (T1_Face_Init), src/type42/t42objs.c (T42_Face_Init): Split on `-' also for searching the style name. 2003-04-24 David Turner <david@freetype.org> * src/pcf/pcfread.c (pcf_load_font): Fixed the computation of face->num_glyphs. We must increase the value by 1 to respect the convention that glyph index 0 always corresponds to the `missing glyph'. 2003-04-24 Werner Lemberg <wl@gnu.org> * builds/unix/unix-cc.in (CFLAGS): Add @CPPFLAGS@. 2003-04-24 Dieter Baron <dillo@netbsd.org> * builds/unix/freetype-config.in (cflags): Emit FreeType 2's include files first. Otherwise there are conflicts with FreeType 1 installed simultaneously. 2003-04-23 Werner Lemberg <wl@gnu.org> Fixing bugs reported by Nelson Beebe. * src/base/ftstroker.c (FT_Stroker_ParseOutline): Remove unused variable `in_path'. * src/base/ftobjs (ft_glyphslot_set_bitmap): Change type of second argument to `FT_Byte'. include/freetype/internal/ftobjs.h: Updated. * src/bdf/bdflib.c (_bdf_readstream): Remove unused variable `res'.

Without this change, many CJK fonts from Dynalab are rejected. 2003-04-23 Joe Marcus Clarke <marcus@FreeBSD.org> * src/base/ftbdf.c (FT_Get_BDF_Property): Check for valid `get_interface'. 2003-04-23 Paul Miller <paulm@profoundeffects.com> * src/base/ftmac.c (parse_fond): Fix handling of style names. 2003-04-23 Werner Lemberg <wl@gnu.org> * src/pfr/pfrload.c (pfr_extra_item_load_font_id): Use FT_PtrDist instead of FT_UInt for `len'. 2003-04-22 Werner Lemberg <wl@gnu.org> * src/gzip/ftgzip.c (zcalloc) [!FT_CONFIG_OPTION_SYSTEM_ZLIB]: Convert K&R format to modern C usage. (FT_Stream_OpenGzip): Use long constant. 2003-04-21 Werner Lemberg <wl@gnu.org> * src/cache/ftccache.c (ftc_cache_lookup): Remove shadow declaration of `manager'. 2003-04-20 Werner Lemberg <wl@gnu.org> * doc/INSTALL.UNX: Cleaned up. 2003-04-09 Torrey Lyons <torrey@mrcla.com> * src/base/ftmac.c (open_face_from_buffer): Removed a double-free bug that had nasty consequences when trying to open an `invalid' font on a Mac. 2003-04-09 Mike Fabian <mfabian@suse.de> * src/bdf/bdfdrivr.h (BDF_encoding_el), src/pcf/pcf.h (PCF_EncodingRec): Changed FT_Short to FT_UShort in order to be able to access more than 32768 glyphs in fonts. 2003-04-08 David Turner <david@freetype.org> * Version 2.1.4 released. ========================= 2003-04-03 Martin Muskens <mmuskens@aurelon.com> * src/type1/t1load.c (T1_Open_Face): Fixed the code to make it handle special cases where a font only contains a `.notdef' glyph (happens in PDF-embedded fonts). Otherwise, FT_Panic was called. 2003-03-27 David Turner <david@freetype.org> * README: Updated. * README.UNX: Removed (now replaced by docs/INSTALL.UNX). * src/pshinter/pshalgo3.c: The hinter now performs as in 2.1.3 and will ignore stem quantization only when FT_LOAD_TARGET_SMOOTH is used. (psh3_dimension_quantize_len): Enabled. (psh3_hint_align): Enable commented code. (psh3_hint_align_light): Commented out. * src/base/ftobjs.c (FT_Set_Char_Size): Changed the default computations to include rounding in all cases; this is required to provide accurate kerning data when native TrueType hinting is enabled. * src/type1/t1load.c (is_name_char): The Type 1 loader now accepts more general names according to the PostScript specification (the previous one was too restrictive). (parse_font_name, parse_encoding, parse_charstrings, parse_dict): Use `is_name_char'. (parse_subrs): Handle empty arrays. 2003-03-20 David Turner <david@freetype.org> Serious rewriting of the documentation. * docs/BUGS, docs/BUILD: Removed. * docs/DEBUG.TXT: Renamed to... * docs/DEBUG: This. * docs/CUSTOMIZE, docs/TRUETYPE, docs/UPGRADE.UNX: New files. * docs/INSTALL.ANY, docs/INSTALL.UNX, docs/INSTALL.GNU New files, containing platform specific information previously in INSTALL. * docs/readme.vms: Renamed to... * docs/INSTALL.VMS: This. * docs/: Updated. Introduced three new functions to deal with glyph bitmaps within FT_GlyphSlot objects: ft_glyphslot_free_bitmap ft_glyphslot_alloc_bitmap ft_glyphslot_set_bitmap These functions are much more convenient to use than managing the FT_GLYPH_OWN_BITMAP flag manually. include/freetype/internal/ftobjs.h (ft_glyphslot_free_bitmap, ft_glyphslot_alloc_bitmap, ft_glyphslot_set_bitmap): New functions. * src/base/ftobjs.c: Implement them. (ft_glyphslot_done): Use ft_glyphslot_free_bitmap. * src/bdf/bdfdrivr.c (BDF_Glyph_Load), src/pcf/pcfdriver.c (PCF_Glyph_Load): Remove unused variable `memory'. Use `ft_glyphslot_' functions. Don't set `FT_GLYPH_OWN_BITMAP'. src/pfr/pfrsbit.c (pfr_slot_load_bitmap): Use `ft_glyphslot_alloc_bitmap'. * src/sfnt/ttsbit.c (Load_SBit_Image): Change 5th argument to type `FT_GlyphSlot'. Adding argument `depth' to handle recursive calls. Use `ft_glyphslot_alloc_bitmap'. (tt_face_load_sbit_image): Remove unused variable `memory'. Don't handle `FT_GLYPH_OWN_BITMAP'. Update call to Load_SBit_Image. * src/type42/t42objs.c (ft_glyphslot_clear): Renamed to... (t42_glyphslot_clear): This. Updated caller. Call `ft_glyphslot_free_bitmap'. * src/winfonts/winfnt.c (FNT_Load_Glyph): Use `ft_glyphslot_set_bitmap'. Don't handle `FT_GLYPH_OWN_BITMAP'. * src/cache/ftlru.c (FT_LruList_Lookup): Fixed an invalid assertion check. * src/autohint/ahglyph.c (ah_outline_load): Add two scaling arguments. * src/autohint/ahglyph.h: Updated. * src/autohint/ahhint.c (ah_hinter_load): Updated. * src/autohint/ahglobal.c (ah_hinter_compute_widths): Updated. * src/cache/ftccache.c (ftc_family_done): Fixed small bug that could crash the cache in rare circumstances (mostly with broken fonts). 2003-03-15 David Turner <david@freetype.org> * src/truetype/ttdriver.c (Set_Char_Sizes): Fixed a small rounding bug. Actually, it seems that previous versions of FreeType didn't perform TrueType rounding exactly as appropriate. 2003-03-14 David Turner <david@freetype.org> * src/truetype/ttdriver.c (Set_Char_Sizes): Fixing the small TrueType native rendering glitches; they came from a small rounding error. 2003-03-13 David Turner <david@freetype.org> Added new environment variables to control memory debugging with FreeType. See the description of `FT2_DEBUG_MEMORY', `FT2_ALLOC_TOTAL_MAX' and `FT2_ALLOC_COUNT_MAX' in DEBUG.TXT. * src/base/ftdbgmem.c (FT_MemTableRec): Add `alloc_count', `bound_total', `alloc_total_max', `bound_count', `alloc_count_max'. (ft_mem_debug_alloc): Handle new variables. (ft_mem_debug_init): s/FT_DEBUG_MEMORY/FT2_DEBUG_MEMORY/. Handle new environment variables. * docs/DEBUG.TXT: Updated. Fixed the cache sub-system to correctly deal with out-of-memory conditions. * src/cache/ftccache.c (ftc_node_destroy): Comment out generic check. (ftc_cache_lookup): Implement loop. * src/cache/ftccmap.c: Define FT_COMPONENT. * src/cache/ftcsbits.c (ftc_sbit_node_load): Handle FT_Err_Out_Of_Memory. * src/cache/ftlru.c: Include FT_INTERNAL_DEBUG_H. (FT_LruList_Lookup): Implement loop. * src/pfr/pfrobjs.c (pfr_face_done): Fix memory leak. (pfr_face_init): Fixing compiler warnings. * src/psaux/psobjs.c (reallocate_t1_table): Fixed a bug (memory leak) that only happened when a try to resize an array would end in an out-of-memory condition. * src/smooth/ftgrays.c (gray_convert_glyph): Removed compiler warnings / volatile bug. * src/truetype/ttobjs.c (tt_glyphzone_done): Removed segmentation fault that happened in tight memory environments. 2003-02-28 Pixel <pixel@mandrakesoft.com> * src/gzip/ftgzip.c (ft_gzip_file_done): Fixed memory leak: The ZLib stream was not properly finalized. 2003-02-25 Anthony Fok <anthony@thizlinux.com> * src/cache/ftccmap.c: Include FT_TRUETYPE_IDS_H. (ftc_cmap_family_init): The cmap cache now supports UCS-4 charmaps when available in Asian fonts. * src/sfnt/ttload.c, src/base/ftobjs.c: Changed `asian' to `Asian' in comments. 2003-02-25 David Turner <david@freetype.org> * src/gzip/ftgzip.c (ft_gzip_file_fill_output): Fixed a bug that caused FreeType to loop endlessly when trying to read certain compressed gzip files. The following test reveals the bug: touch 0123456789 ; gzip 0123456789 ; ftdump 0123456789.gz Several fixes to the PFR font driver: - The list of available embedded bitmaps was not correctly set in the root FT_FaceRec structure describing the face. - The glyph loader always tried to load the outlines when FT_LOAD_SBITS_ONLY was specified. - The table loaded now scans for undocumented elements of a physical font's auxiliary data record. This is necessary to retrieve the `real' family and style names. NOTE THAT THESE CHANGES THE FAMILY NAME OF MANY PFR FONTS! * src/pfr/pfrload.c (pfr_aux_name_load): New function. (pfr_phy_font_done): Free `family_name' and `style_name' also. Remove unused variables. (pfr_phy_font_load): Extract useful information from the auxiliary bytes. * src/pfr/pfrobjs.c (pfr_face_done): Set pointers to NULL. (pfr_face_init): Provide fallback values for `family_name' and `style_name'. Handle strikes. (pfr_slot_load): Handle FT_LOAD_SBITS_ONLY. * src/pfr/pfrtypes.h (PFR_PhyFontRec): Add fields `ascent', `descent', `leading', `family_name', and `style_name'. * src/truetype/ttdriver.c (Set_Char_Sizes): Fixed a rounding bug when computing the scale factors for a given character size in points with resolution. * devel/ft2build.h, devel/ftoption.h: New files (in a new directory) which are special development versions of include/ft2build.h and include/freetype/config/ftoption.h, respectively. 2003-02-18 David Turner <david@freetype.org> Fixing the slight distortion problem that occurred due to the latest auto-hinter changes. * src/base/ftobjs.c (ft_recompute_scaled_metrics): Fix rounding. * src/truetype/ttdriver.c (Set_Char_Sizes): New variable `metrics2'. [!TT_CONFIG_OPTION_BYTECODE_INTERPRETER]: Removed. * src/truetype/ttobjs.h (TT_SizeRec): New field `metrics'. * src/truetype/ttobjs.c (Reset_Outline_Size): Fix initialization of `metrics'. [FT_CONFIG_CHESTER_ASCENDER]: Code removed. (Reset_SBit_Size): Fix initialization of `metrics'. * src/truetype/ttinterp.c (TT_Load_Context): Fix initialization of `exec->metrics'. * src/autohint/ahhint.c (ah_hinter_load): Disabled the advance width `correction' which seemed to provide more trouble than benefits. 2003-02-13 Graham Asher <graham.asher@btinternet.com> Changed the incremental loading interface in a way that makes it simpler and allows glyph metrics to be changed (e.g., by adding a constant, as required by CFF fonts) rather than just overridden. This was required to make the GhostScript-to-FreeType bridge work. * src/cff/cffgload.c (cff_slot_load) [FT_CONFIG_OPTION_INCREMENTAL]: Allow metrics to be overridden. * src/cid/cidgload.c (cid_load_glyph) [FT_CONFIG_OPTION_INCREMENTAL]: Ditto. * src/truetype/ttgload.c (load_truetype_glyph) [FT_CONFIG_OPTION_INCREMENTAL]: Simplify. (compute_glyph_metrics) [FT_CONFIG_OPTION_INCREMENTAL]: Code block moved down. * src/type1/t1gload.c (T1_Parse_Glyph_And_Get_Char_String) [FT_CONFIG_OPTION_INCREMENTAL]: Updated. * include/freetype/ftincrem.h: Updated. 2003-01-31 David Turner <david@freetype.org> * docs/CHANGES, docs/VERSION.DLL, docs/TODO: Updating documentation for the 2.1.4 release. * builds/win32/visualc/freetype.dsp, builds/win32/visualc/index.html: Updating the project file for 2.1.4. * src/gzip/adler32.c, src/gzip/ftgzip.c, src/gzip/infblock.c, src/gzip/infcodes.c, src/gzip/inflate.c, src/gzip/inftrees.c, src/gzip/infutil.c: Removed old-style (K&R)function definitions. This avoids warnings with Visual C++ at its most pedantic mode. * src/pfr/pfrsbit.c: Removed compiler warnings. * src/cache/ftccmap.c (ftc_cmap_family_init): Changed an FT_ERROR into an FT_TRACE1 since it caused `ftview' and others to dump too much junk when trying to display a waterfall with a font without a Unicode charmap (e.g. SYMBOL.TTF). Implemented FT_CONFIG_CHESTER_BLUE_SCALE, corresponding to the last patch from David Chester, but with a much simpler (and saner) implementation. * src/autohint/ahhint.c (ah_hinter_load_glyph) [FT_CONFIG_CHESTER_BLUE_SCALE]: Try to optimize the y_scale so that the top of non-capital letters is aligned on a pixel boundary whenever possible. * src/base/ftobjs.c (FT_Set_Char_Size) [FT_CONFIG_CHESTER_BLUE_SCALE]: Round differently. * src/truetype/ttdriver.c (Set_Char_Sizes) [TT_CONFIG_OPTION_BYTECODE_INTERPRETER]: Do some rounding only if this macro is defined. * src/truetype/ttobjs.c (Reset_Outline_Size) [FT_CONFIG_CHESTER_ASCENDER]: Round differently. * src/pshinter/pshalgo3.c: Improved the Postscript hinter. Getting rid of stem snapping seems to work well here (though the stems are still slightly moved to increase contrast). (psh3_dimension_quantize_len): Commented out. (psh3_hint_align_light): New function. (psh3_hint_align): Comment out some code. THIS IMPROVES ANTI-ALIASED RENDERING, BUT MONOCHROME AND LCD MODES STILL SUCK. 2003-01-22 David Chester <davidchester@qmx.net> * src/autohint/ahhint.c (ah_compute_stem_width): Small fix to the stem width optimization. 2003-01-22 David Turner <david@freetype.org> Adding a new API `FT_Get_BDF_Property' to retrieve the BDF properties of a given PCF or BDF font. * include/freetype/ftbdf.h (BDF_PropertyType): New enumeration. (BDF_Property, BDF_PropertyRec): New structure. FT_Get_BDF_Property): New function. * include/freetype/internal/bdftypes.h: Include FT_BDF_H.

(bdf_driver_class): Use `bdf_driver_requester'. * src/pcf/pcfdrivr.c: Include FT_BDF_H. (pcf_get_bdf_property, pcf_driver_requester): New functions (pcf_driver_class): Use `pcf_driver_requester'. * src/pcf/pcfread.c: Include `pcfread.h'. (pcf_find_property): Decorate it with FT_LOCAL_DEF. * src/pcf/pcfread.h: New file, providing `pcf_find_property'. * src/sfnt/ttload.c (sfnt_dir_check): Relaxed the `head' table size verification to accept a few broken fonts who pad the size incorrectly (the table should be padded, but its `size' field shouldn't according to the specification). 2003-01-18 Werner Lemberg <wl@gnu.org> * builds/unix/ltmain.sh: Regenerated with `libtoolize --force --copy' from libtool 1.4.3. * builds/unix/aclocal.m4: Regenerated with `aclocal -I .' from automake 1.7.1. * builds/unix/configure: Regenerated with autoconf 2.54. * builds/unix/config.guess, builds/unix/config.sub: Updated from `config' CVS module at subversions.gnu.org. * builds/unix/install-sh, builds/unix/mkinstalldirs: Updated from `automake' CVS module at subversions.gnu.org. 2003-01-15 David Turner <david@freetype.org> * include/freetype/freetype.h: Fixed documentation for FT_Size_Metrics. 2003-01-15 James Su <suzhe@turbolinux.com.cn> * src/gzip/ftgzip.c (ft_gzip_check_header): Bugfix: couldn't read certain gzip-ed font files (typo: `&&' -> `&'). 2003-01-15 Huw D M Davies <h.davies1@physics.ox.ac.uk> Added a Windows .FNT specific API (mostly for Wine). Also fixed a nasty bug in the header loader which would cause invalid memory overwrites. * include/freetype/config/ftheader.h (FT_WINFONTS_H): New macro for ftwinfnt.h. * include/freetype/internal/fnttypes.h: Include FT_WINFONTS_H. (FNT_FontRec): Updated. Move Windows FNT definition to... * include/freetype/ftwinfnt.h: This new file. (FT_WinFNT_HeaderRec): Rename `reserved2' to `reserved1'. * src/base/ftwinfnt.c: New file, providing `FT_Get_WinFNT_Header'. * src/winfonts/winfnt.c (winfnt_header_fields): Updated. Rename `reserved2' to `reserved1'. (fnt_font_load): Updated. * src/base/Jamfile, src/base/descrip.mms, src/base/rules.mk: Updated. 2003-01-14 Graham Asher <graham.asher@btinternet.com> * include/freetype/ftglyph.h, src/base/ftglyph.c: Added `const' to the type of the first argument to FT_Matrix_Multiply, which isn't changed -- this adds documentation and convenience. 2003-01-13 Graham Asher <graham.asher@btinternet.com> * src/sfnt/ttload.c (tt_face_load_metrics) [FT_CONFIG_OPTION_INCREMENTAL]: TrueType typefaces without horizontal metrics (without the `hmtx' table) are now tolerated if an incremental interface has been specified that has a get_glyph_metrics function, implying that metrics will be supplied from outside. This happens for certain Type 42 fonts passed from GhostScript. 2003-01-11 David Chester <davidchester@qmx.net> Patches to the auto-hinter in order to slightly improve the output. Note that everything is controlled through the new FT_CONFIG_OPTION_CHESTER_HINTS defined in `ftoption.h'. There are also individual FT_CONFIG_CHESTER_XXX macros to control individual `features'. Note that all improvements are enabled by default, but can be tweaked for optimization and testing purposes. The configuration macros will most likely disappear in the short future. * include/freetype/config/ftoption.h (FT_CONFIG_OPTION_CHESTER_HINTS): New macro. (FT_CONFIG_CHESTER_{SMALL_F,ASCENDER,SERIF,STEM,BLUE_SCALE}) [FT_CONFIG_OPTION_CHESTER_HINTS]: New macros to control individual features. * src/autohint/ahglobal.c (blue_chars) [FT_CONFIG_CHESTER_SMALL_F]: Add blue zone for `fijkdbh'. * src/autohint/ahglobal.h (AH_IS_TOP_BLUE) [FT_CONFIG_CHESTER_SMALL_F]: Use `AH_BLUE_SMALL_F_TOP'. * src/autohint/ahglyph.c (ah_outline_compute_edges) [FT_CONFIG_CHESTER_SERIF]: Use `AH_EDGE_SERIF'. (ah_outline_compute_blue_edges) [FT_CONFIG_CHESTER_SMALL_F]: Increase threshold for `best_dist'. * src/autohint/ahhint.c (ah_compute_stem_width) [FT_CONFIG_CHESTER_SERIF]: Provide new version for improved serif handling. (ah_align_linked_edge) [FT_CONFIG_CHESTER_SERIF]: Use special version of `ah_compute_stem_width'. (ah_hint_edges_3) [FT_CONFIG_CHESTER_STEM]: A new algorithm for stem alignment when stem widths are less than 1.5 pixels wide centers the stem slightly off-center of the center of a pixel (this increases sharpness and consistency). [FT_CONFIG_CHESTER_SERIF]: Use special version of `ah_compute_stem_width'. * src/autohint/ahtypes.h [FT_CONFIG_CHESTER_SMALL_F]: Add `AH_BLUE_SMALL_F_TOP'. 2003-01-11 David Turner <david@freetype.org> * include/freetype/internal/fnttypes.h (WinFNT_HeaderRec): Increase size of `reserved2' to avoid memory overwrites. 2003-01-08 Huw Davies <huw@codeweavers.com> * src/winfonts/winfnt.c (winfnt_header_fields): Read 16 bytes into `reserved2', not `reserved'. * src/base/ftobjs.c (find_unicode_charmap): Fixed the error code returned when the font doesn't contain a Unicode charmap. This allows FT2 to load `symbol.ttf' and a few others correctly since the last release. (open_face): Fix return value. 2003-01-08 Owen Taylor <owen@redhat.com> Implemented the FT_RENDER_MODE_LIGHT hinting mode in the auto and postscript hinters. * src/autohint/ahtypes.h (AH_HinterRec): Add `do_stem_adjust'. * src/autohint/ahhint.c (ah_compute_stem_width): Handle hinter->do_stem_adjust. (ah_hinter_load_glyph): Set hinter->do_stem_adjust. * src/pshinter/pshalgo3.h (PSH3_GlyphRec): Add `do_stem_adjust'. * src/pshinter/pshalgo3.c (psh3_hint_align): Use `do_stem_adjust'. (ps3_hints_apply): Handle FT_RENDER_MODE_LIGHT. * include/freetype/freetype.h (FT_Render_Mode): Add FT_RENDER_MODE_LIGHT. * src/truetype/ttgload.c: Fixing the TrueType loader to handle invalid composites correctly by limiting the recursion depth. (TT_MAX_COMPOSITE_RECURSE): New macro. (load_truetype_glyph): Add argument `recurse_count'. Load a composite only if the numbers of contours is -1, emit error otherwise. (TT_Load_Glyph): Updated. 2003-01-08 David Turner <david@freetype.org> * Jamrules, Jamfile, Jamfile.in, src//Jamfile: Small changes to support the compilation of FreeType 2 as part of larger projects with their own configuration options (only with Jam). 2003-01-07 David Turner <david@freetype.org> src/base/ftstroker.c: Probably the last bug-fixes to the stroker; the API is likely to change, however.

(winfnt_header_fields): Updated. (fnt_font_load): Handle version 2 fonts. (FNT_Load_Glyph): Updated. 2002-12-16 David Turner <david@freetype.org> * docs/VERSION.DLL: Updating document to better explain the differences between the three version numbers being used on Unix, as well as providing an autoconf fragment provided by Lars Clausen. * src/smooth/ftgrays.c (gray_render_conic): Fixed small bug that prevented Bézier arcs with negative vertical coordinates to be rendered appropriately. 2002-12-02 Antoine Leca <Antoine-Freetype@Leca-Marti.org> * src/base/ftobjs.c: Modified the logic to get Unicode charmaps. Now it loads UCS-4 charmaps when there is one. (find_unicode_charmap): New function. (open_face): Refer to the above one. (FT_Select_Charmap): Idem. 2002-11-29 Antoine Leca <Antoine-Freetype@Leca-Marti.org> * include/freetype/ftgzip.h: Correct the name of the controlling macro (was __FTXF86_H__ ...). 2002-11-27 Vincent Caron <v.caron@zerodeux.net> * builds/unix/unix-def.in, builds/unix/freetype-config.in, builds/unix/configure.ac, src/gzip/rules.mk, src/gzip/ftgzip.c [FT_CONFIG_OPTION_SYSTEM_ZLIB]: Adding support for system zlib installations if available on the target platform (Unix only). 2002-11-23 David Turner <david@freetype.org> * src/cff/cffload.c (cff_charset_load, cff_encoding_load): Modified charset loader to accept pre-defined charsets, even when the font contains fewer glyphs. Also enforced more checks to ensure that we never overflow the character codes array in the encoding. 2002-11-22 Antoine Leca <Antoine-Freetype@Leca-Marti.org> * include/freetype/ttnameid.h: Updated to latest OpenType specification. 2002-11-18 David Turner <david@freetype.org> * Version 2.1.3 released. ========================= 2002-11-07 David Turner <david@freetype.org> * src/cache/ftcsbits.c (ftc_sbit_node_load): Fixed a small bug that caused problems with embedded bitmaps. * src/otlayout/otlayout.h, src/otlayout/otlconf.h, src/otlayout/otlgsub.c, src/otlayout/otlgsub.h, src/otlayout/otlparse.c, src/otlayout/otlparse.h, src/otlayout/otlutils.h: Updating the OpenType Layout code, adding support for the first GSUB lookups.

This allows the build system to define them depending on the configuration (typically by adding -D flags at compile time). * src/sfnt/ttcmap0.c (tt_face_build_cmaps): Removed compiler warnings in optimized mode relative to the `volatile' local variables. This was not a compiler bug after all, but the fact that a pointer to a volatile variable is not the same as a volatile pointer to a variable :-) The fix was to change `volatile FT_Byte* p' into `FT_Byte* volatile p'. * src/pfr/pfrload.c (pfr_phy_font_load), src/pfr/pfrdrivr.c (pfr_get_metrics), src/gzip/inftrees.c: Removed compiler warnings in optimized modes. * src/gzip/.[hc]: Modified our zlib copy in order to prevent exporting any zlib function names outside of the component.

(FT_EXPORT, FT_EXPORT_DEF, FT_DEBUG_LEVEL_ERROR, FT_DEBUG_LEVEL_TRACE, FT_DEBUG_MEMORY): Comment out definitions so that platform specific configuration file can override. * include/freetype/internal/ftstream.h: Include FT_SYSTEM_H. 2002-10-30 David Turner <david@freetype.org> * FreeType 2.1.3rc3 released. 2002-10-25 David Turner <david@freetype.org> * include/freetype/ftcache.h (FT_POINTER_TO_ULONG): New macro. (FTC_FACE_ID_HASH): Rewritten, using FT_POINTER_TO_ULONG. 2002-10-22 Giuseppe Ghibò <ghibo@mandrakesoft.com> * include/freetype/freetype.h (FT_Encoding): Fix entry for latin-2. 2002-10-07 Werner Lemberg <wl@gnu.org> * include/freetype/freetype.h (FT_Open_Face): Use `const' for `args' (suggested by Graham). * src/base/ftobjs.c (FT_Open_Face): Updated.

(tt_face_): This. 2002-08-27 Werner Lemberg <wl@gnu.org> * docs/VERSION.DLL: New file. 2002-08-23 Graham Asher <graham.asher@btinternet.com> * src/cff/cffgload.c (cff_operator_seac) [FT_CONFIG_OPTION_INCREMENTAL]: Incremental fonts (actually not incremental in the case of CFF but just using callbacks to get glyph recipes) pass the character code, not the glyph index, to the get_glyph_data function; they have no valid charset table. * src/cff/cffload.c (cff_font_load): Removed special cases for FT_CONFIG_OPTION_INCREMENTAL, which are no longer necessary; CFF fonts provided via the incremental interface now have to conform more closely to the CFF font format. * src/cff/cffload.h (cff_font_load): Removed argument now unneeded. * src/cff/cffobjs.c (cff_face_init): Changed call to cff_font_load to conform with new signature. 2002-08-22 David Turner <david@freetype.org> * src/base/ftobject.c, src/base/ftsynth.c, src/base/ftstroker.c, src/bdf/bdfdrivr.c: Removed compiler warnings. 2002-08-21 Werner Lemberg <wl@gnu.org> * src/pshinter/pshalgo3.c (psh3_glyph_compute_inflections, psh3_glyph_compute_extrema, psh3_hint_table_find_strong_point): Fix compiler warnings and resolve shadowing of local variables. 2002-08-21 David Turner <david@freetype.org> The automatic and Postscript hinter now automatically detect inflection points in glyph outlines and treats them specially. This is very useful to prevent nasty effect like the disappearing diagonals of `S' and `s' in many, many fonts. * src/autohint/ahtypes.h (ah_flag_inflection): New macro. * src/autohint/ahangles.c (ah_angle_diff): New function. * src/autohint/ahangles.h: Updated. * src/autohint/ahglyph.c (ah_outline_compute_inflections): New function.

This should only break binary and/or source compatibility on 16-bit platforms (Atari?). (FT_LOAD_NO_AUTOHINT): New macro. * src/base/ftobjs.c (FT_Load_Glyph): Updated. Handle FT_LOAD_NO_AUTOHINT. (FT_Load_Char): Updated. * src/pshinter/pshalgo3.c, src/base/ftobjs.c, src/base/ftobject.c, src/autohint/ahglyph.c, include/freetype/freetype.h: Fixing typos and removing compiler warnings. 2002-08-20 Werner Lemberg <wl@gnu.org> * src/truetype/ttgload.c (TT_Get_Metrics): Add guard for k = 0. 2002-08-20 David Turner <david@freetype.org> * src/pshinter/pshalgo1.c, src/pshinter/pshalgo2.c, src/pshinter/pshglob.c, src/pshinter/pshrec.c, src/autohint/ahmodule.c [DEBUG_HINTER]: Removing compiler warnings (only used in development builds anyway). Improve support of local extrema and stem edge points. * src/pshinter/pshalgo3.h (PSH3_Hint_TableRec): Use PSH3_ZoneRec for `zones'. (PSH3_DIR_UP, PSH3_DIR_DOWN): Exchange values. (PSH3_DIR_HORIZONTAL, PSH3_DIR_VERTICAL): New macros. (PSH3_DIR_COMPARE, PSH3_DIR_IS_HORIZONTAL, PSH3_IS_VERTICAL): New macros. (PSH3_POINT_INFLEX): New enum. (psh3_point_{is,set}_{off,inflex}): New macros. (PSH3_POINT_{EXTREMUM,POSITIVE,NEGATIVE,EDGE_MIN,EDGE_MAX): New enum values. (psh3_point_{is,set}_{extremum,positive,negative,edge_min,edge_max}): New macros. (PSH3_PointRec): New members `flags2' and `org_v'. (PSH3_POINT_EQUAL_ARG, PSH3_POINT_ANGLE): New macros. * src/pshinter/pshalgo3.c [DEBUG_HINTER]: Removing compiler warnings. (COMPUTE_INFLEXS): New macro. (psh3_hint_align): Simplify some basic arithmetic computations. (psh3_point_is_extremum): Removed. (psh3_glyph_compute_inflections) [COMPUTE_INFLEXS]: New function. (psh3_glyph_init) [COMPUTE_INFLEXS]: Use it. (psh3_glyph_compute_extrema): New function. (PSH3_STRONG_THRESHOLD): Increased to 30. (psh3_hint_table_find_strong_point): Improved. (psh3_glyph_find_strong_points, psh3_glyph_interpolate_strong_points): Updated. (psh3_hints_apply): Use psh3_glyph_compute_extrema. * test/gview.c (draw_ps3_hint, ps3_draw_control_points): New functions. Other small updates. * Jamfile: Small updates. 2002-08-18 Arkadiusz Miskiewicz <misiek@pld.ORG.PL> * builds/unix/install.mk (install, uninstall): Add $(DESTDIR) to make life easier for package maintainers. 2002-08-18 Werner Lemberg <wl@gnu.org> * src/pcf/pcfdriver.c (PCF_Glyph_Load): Fix computation of horiBearingX. * src/bdf/bdfdrivr.c (BDF_Glyph_Load): Fix computation of horiBearingY. 2002-08-16 George Williams <gww@silcom.com> Add support for Apple composite glyphs. * include/freetype/config/ftoption.h (TT_CONFIG_OPTION_COMPONENT_OFFSET_SCALED): New macro. * src/truetype/ttgload.c (OVERLAP_COMPOUND, SCALED_COMPONENT_OFFSET, UNSCALED_COMPONENT_OFFSET): New macros for additional OpenType glyph loading flags. (load_truetype_glyph): Implement it. 2002-08-16 Werner Lemberg <wl@gnu.org> * src/cff/cffgload.c (cff_free_glyph_data), src/cff/cffload.c (cff_font_load): Use FT_UNUSED. 2002-08-15 Werner Lemberg <wl@gnu.org> * src/base/ftglyph.c (FT_Glyph_To_Bitmap): Initialize `error'. * src/sfnt/sfobjs.c (SFNT_Load_Face): Fix compiler warning. 2002-08-15 Graham Asher <graham.asher@btinternet.com> Implemented the incremental font loading system for the CFF driver. Tested using the GhostScript-to-FreeType bridge (under development). * src/cff/cffgload.c (cff_get_glyph_data, cff_free_glyph_data): New functions. (cff_operator_seac, cff_compute_max_advance, cff_slot_load): Use them. * src/cff/cffload.c (cff_font_load): Add `face' parameter. Load charset and encoding only if there are glyphs. [FT_CONFIG_OPTION_INCREMENTAL]: Incremental fonts don't need character recipes. * src/cff/cffload.h, src/cff/cffobjs.c: Updated. * src/cid/cidgload.c (cid_load_glyph) [FT_CONFIG_OPTION_INCREMENTAL]: Corrected the incremental font loading implementation to use the new system introduced on 2002-08-01. 2002-08-06 Werner Lemberg <wl@gnu.org> * src/cff/cffcmap.c: Remove compiler warnings. * src/cache/ftccache.c, src/cache/ftccache.i, src/pfr/pfrload.c, src/pfr/pfrgload.c: s/index/idx/. * src/cff/cffload.c: s/select/fdselect/. * src/raster/ftraster.c: s/wait/waiting/. 2002-08-01 Graham Asher <graham.asher@btinternet.com> * src/type1/t1load.c (T1_Open_Face): Tolerate a face with no charstrings if there is an incremental loading interface. Type 1 faces supplied by PostScript interpreters like GhostScript will typically not provide any charstrings at load time, so this is essential if they are to work. 2002-08-01 Graham Asher <graham.asher@btinternet.com> Modified incremental loading interface to be closer to David's preferences. The header freetype.h is not now affected, the interface is specified via an FT_Parameter, the pointer to the interface is hidden in an internal part of the face record, and all the definitions are in ftincrem.h. * include/freetype/freetype.h [FT_CONFIG_OPTION_INCREMENTAL]: Removed. * include/freetype/internal/ftobjs.h [FT_CONFIG_OPTION_INCREMENTAL]: Include FT_INCREMENTAL_H. (FT_Face_InternalRec) [FT_CONFIG_OPTION_INCREMENTAL]: Add `incremental_interface'. * src/base/ftobjs.c (open_face, FT_Open_Face) [FT_CONFIG_OPTION_INCREMENTAL]: Updated. * src/sfnt/sfobjs.c (SFNT_Load_Face) [FT_CONFIG_OPTION_INCREMENTAL]: Updated. * src/truetype/ttgload.c (load_truetype_glyph) [FT_CONFIG_OPTION_INCREMENTAL]: Updated. Free loaded glyph data properly. (compute_glyph_metrics, TT_Load_Glyph) [FT_CONFIG_OPTION_INCREMENTAL]: Updated. * src/truetype/ttobjs.c (TT_Face_Init) [FT_CONFIG_OPTION_INCREMENTAL]: Updated. * src/type1/t1gload.c (T1_Parse_Glyph_And_Get_Char_String) [FT_CONFIG_OPTION_INCREMENTAL]: Updated. (T1_Parse_Glyph) [FT_CONFIG_OPTION_INCREMENTAL]: Updated. Free loaded glyph data properly. (T1_Load_Glyph): Updated. [FT_CONFIG_OPTION_INCREMENTAL]: Free loaded glyph data properly. 2002-07-30 David Turner <david@freetype.org> * include/freetype/ftincrem.h: Adding new experimental header file to demonstrate a `cleaner' API to support incremental font loading. * include/freetype/config/ftheader.h (FT_INCREMENTAL_H): New macro. * src/tools/docmaker/: Adding new (more advanced) version of the DocMaker tool, using Python's sophisticated regexps. 2002-07-28 Werner Lemberg <wl@gnu.org> s/ft_memset/FT_MEM_SET/. s/FT_MEM_SET/FT_MEM_ZERO/ where appropriate. 2002-07-27 Werner Lemberg <wl@gnu.org> src/sfnt/ttload.c (sfnt_dir_check): Make it work with TTCs. 2002-07-26 Werner Lemberg <wl@gnu.org> * src/truetype/ttgload.c (load_truetype_glyph) [FT_CONFIG_OPTION_INCREMENTAL]: s/memset/ft_memset/. * src/autohint/ahhint.c (ah_hint_edges_3): Fix compiler warning. * src/cff/cffload.c (cff_encoding_load): Remove `memory' variable. * src/cff/cffcmap.c (cff_cmap_encoding_init): Remove `psnames' variable. * src/truetype/ttgload.c (load_truetype_glyph): Remove statement without effect. * src/truetype/ttdriver (Get_Char_Index, Get_Next_Char): Removed. * src/pshinter/pshalgo3.c (psh3_hint_table_record, psh3_hint_table_init, psh3_hint_table_activate_mask): Fix error message. 2002-07-24 Graham Asher <graham.asher@btinternet.com> * src/truetype/ttobjs.c: Fix for bug reported by Sven Neumann [sven@gimp.org] on the FreeType development forum: `If FT_CONFIG_OPTION_INCREMENTAL is undefined (this is the default), the TrueType loader crashes in line 852 of src/truetype/ttgload.c when it tries to access face->glyph_locations.' 2002-07-18 Graham Asher <graham.asher@btinternet.com> Added types and structures to support incremental typeface loading. The FT_Incremental_Interface structure, defined in freetype.h, is designed to be passed to FT_Open_Face to provide callback functions to obtain glyph recipes and metrics, for fonts like those passed from PostScript that do not necessarily provide all, or any, glyph information, when first opened. * include/freetype/config/ftoption.h (FT_CONFIG_OPTION_INCREMENTAL): New configuration macro to enable incremental face loading. By default it is not defined. * include/freetype/freetype.h (FT_Basic_Glyph_Metrics, FT_Get_Glyph_Data_Func, FT_Get_Glyph_Metrics_Func, FT_Incremental_Interface_Funcs, FT_Incremental_Interface) [FT_CONFIG_OPTION_INCREMENTAL]: New.

(FT_Data): New structure to represent binary data. * src/base/ftobjs.c (open_face) [FT_CONFIG_OPTION_INCREMENTAL]: Add parameter for incremental loading. (FT_Open_Face) [FT_CONFIG_OPTION_INCREMENTAL]: Use incremental interface. * src/truetype/ttgload.c (load_truetype_glyph) [FT_CONFIG_OPTION_INCREMENTAL]: Added the incremental loading system for the TrueType driver. (compute_glyph_metrics): Return FT_Error. [FT_CONFIG_OPTION_INCREMENTAL]: Check for overriding metrics. (TT_Load_Glyph) [FT_CONFIG_OPTION_INCREMENTAL]: Don't look for the glyph table while handling an incremental font. Get glyph offset. * src/truetype/ttobjs.c (TT_Face_Init) [FT_CONFIG_OPTION_INCREMENTAL]: Added the incremental loading system for the TrueType driver. * src/cid/cidgload.c (cid_load_glyph) [FT_CONFIG_OPTION_INCREMENTAL]: Added the incremental loading system for the CID driver. * src/sfnt/sfobjs.c (SFNT_Load_Face) [FT_CONFIG_OPTION_INCREMENTAL]: Changes to support incremental Type 42 fonts: Assume a font has glyphs if it has an incremental interface object. * src/type1/t1gload.c (T1_Parse_Glyph): Renamed to... (T1_Parse_Glyph_And_Get_Char_String): This. [FT_CONFIG_OPTION_INCREMENTAL]: Added support for incrementally loaded Type 1 faces. (T1_Parse_Glyph): New function. (T1_Load_Glyph): Updated. 2002-07-17 David Turner <david@freetype.org> Cleaning up the cache sub-system code; linear hashing is now the default. * include/freetype/cache/ftccache.h, src/cache/ftccache.i, src/cache/ftccache.c [!FTC_CACHE_USE_LINEAR_HASHING]: Removed.

The new cmap code is now the default. * src/type42/t42objs.c (T42_CMap_CharIndex, T42_CMap_CharNext): Removed. * src/type42/t42objs.h: Updated. * src/cid/cidriver.c (Cid_Get_Char_Index, Cid_Get_Next_Char): Removed. (t1cid_driver_class): Updated. * src/truetype/ttdriver.c (tt_driver_class): Updated. * src/type1/t1driver.c (Get_Char_Index, Get_Next_Char): Removed (t1_driver_class): Updated. * src/type42/t42drivr.c (t42_driver_class): Updated. * src/base/ftobjs.c (open_face): Select Unicode cmap by default. * src/sfnt/ttload.c (TT_Load_SFNT_Header): Fixed a recent bug that prevented OpenType fonts to be recognized by FreeType. 2002-07-11 David Turner <david@freetype.org> Changing the SFNT loader to check for SFNT-based font files differently. We now ignore the range `helper' fields and check the `head' table's magic number instead. * include/freetype/internal/tttypes.h (SFNT_HeaderRec): Add `offset' field. * src/sfnt/ttload.c (sfnt_dir_check): New function. (TT_Load_SFNT_HeaderRec): Renamed to... (TT_Load_SFNT_Header): This.

Fixing a bug in the Type 1 loader that prevented valid font bounding boxes to be loaded from multiple master fonts. * include/freetype/t1tables.h (PS_BlendRec): Add `bboxes' field. * include/freetype/internal/psaux.h (T1_FieldType): Add `T1_FIELD_TYPE_BBOX'. (T1_FieldLocation): Add `T1_FIELD_LOCATION_BBOX'.

Add `count' member. (CFF_FontRec): Add `psnames' member. * src/cff/cffdrivr.c, src/cff/cffload.c, src/cff/cffload.h, src/cff/cffobjs.c, src/cff/cffobjs.h, src/cff/cffparse.c, src/cffparse.h, src/cff/cffgload.c, src/cff/cffgload.h: Adding support for CFF charmaps, reformatting the sources, and removing some bugs in the Encoding and Charset loaders. Many fonts renamed to use lowercase only: CFF_Builder_Init -> cff_builder_init CFF_Builder_Done -> cff_builder_done CFF_Init_Decoder -> cff_decoder_init CFF_Parse_CharStrings -> cff_decoder_parse_charstrings CFF_Load_Glyph -> cff_slot_load CFF_Init_Decoder -> cff_decoder_init CFF_Prepare_Decoder -> cff_decoder_prepare CFF_Get_Standard_Encoding -> cff_get_standard_encoding CFF_Access_Element -> cff_index_access_element CFF_Forget_Element -> cff_index_forget_element CFF_Get_Name -> cff_index_get_name CFF_Get_String -> cff_index_get_sid_string CFF_Get_FD -> cff_fd_select_get CFF_Done_Charset -> cff_charset_done CFF_Load_Charset -> cff_charset_load CFF_Done_Encoding -> cff_encoding_done CFF_Load_Encoding -> cff_encoding_load CFF_Done_SubFont -> cff_subfont_done CFF_Load_Font -> cff_font_load CFF_Done_Font -> cff_font_done CFF_Size_Get_Globals_Funcs -> cff_size_get_globals_funcs CFF_Size_Done -> cff_size_done CFF_Size_Init -> cff_size_init CFF_Size_Reset -> cff_size_reset CFF_GlyphSlot_Done -> cff_slot_done CFF_GlyphSlot_Init -> cff_slot_init CFF_StrCopy -> cff_strcpy CFF_Face_Init -> cff_face_init CFF_Face_Done -> cff_face_done CFF_Driver_Init -> cff_driver_init CFF_Driver_Done -> cff_driver_done CFF_Parser_Init -> cff_parser_init CFF_Parser_Run -> cff_parser_run add_point -> cff_builder_add_point add_point1 -> cff_builder_add_point1 add_contour -> cff_builder_add_contour close_contour -> cff_builder_close_contour cff_explicit_index -> cff_index_get_pointers 2002-07-09 Owen Taylor <owen@redhat.com> * src/pshinter/pshglob.c (psh_globals_new): Fixed a bug that prevented the hinter from using correct standard width and height values, resulting in hinting bugs with certain fonts (e.g. Utopia). 2002-07-07 David Turner <david@freetype.org> * src/base/ftglyph.c (FT_Glyph_To_Bitmap): Added code to return successfully when the function is called with a bitmap glyph (the previous code simply returned with an error). * docs/DEBUG.TXT: Adding debugging support documentation. * src/base/ftdebug.c (ft_debug_init), builds/win32/ftdebug.c (ft_debug_init), builds/amiga/src/ftdebug.c (ft_debug_init): Changed the syntax of the FT2_DEBUG environment variable used to control debugging output (i.e. logging and error messages).

They provide a new API (FT_Get_X11_Font_Format) to retrieve an X11-compatible string describing the font format of a given face. This was put in a new optional base source file, corresponding to a new public header (named FT_XFREE86_H since this function should only be used within the XFree86 font server IMO). * include/freetype/config/ftheader.h (FT_XFREE86_H): New macro (not documented yet). * src/base/fttype1.c: New file, providing two new API functions (FT_Get_PS_Font_Info and FT_Has_PS_Glyph_Names). * include/freetype/t1tables.h: Updated. * src/base/Jamfile, src/base/rules.mk, src/base/descrip.mms: Updating build control files for the new files `ftxf86.c' and `fttype1.c' in src/base. * src/pshinter/pshglob.c (psh_blues_scale_zones): Fixed a bug that prevented family blue zones substitution from happening correctly. * include/freetype/ftbdf.h FT_Get_BDF_Charset_ID): Adding documentation comment. 2002-05-28 Werner Lemberg <wl@gnu.org> * src/base/ftnames.c (FT_Get_Sfnt_Name): Don't use FT_STREAM_READ_AT but FT_STREAM_READ.

It now ignores empty name entries, entries with invalid pointer Offsets and certain fonts containing tables with broken `storageOffset' fields. Name strings are now loaded on demand, which reduces the memory requirements for a given FT_Face tremendously (for example, the name table of Arial.ttf is about 10Kb and contains 70 names). This is a temporary fix. The whole name table loader and interface will be rewritten in a much more cleanly way shortly, once CSEH have been introduced in the sources. * include/freetype/internal/tttypes.h (TT_NameEntryRec): Change type of `stringOffset' to FT_ULong.

(TT_Free_Names): Updated. 2002-05-24 Tim Mooney <enchanter@users.sourceforge.net> * builds/unix/ft-munmap.m4: New file, extracted FT_MUNMAP_DECL and FT_MUNMAP_PARAM from aclocal.m4 into here, so aclocal.m4 can be rebuilt from sources. Set macro serial to 1, and use third argument to AC_DEFINE for our two custom symbols, so ftconfig.in could one day be rebuilt with autoheader (not recommended now, ftconfig.in is a custom source file) 2002-05-22 Werner Lemberg <wl@gnu.org> * include/freetype/config/ftheader.h (FT_BEZIER_H): Removed. (FT_BDF_H): New macro for accessing `ftbdf.h'. * src/type42/t42drivr.c (hexval): Fix typo. 2002-05-21 Martin Muskens <mmuskens@aurelon.com> * src/psaux/psobjs.c (T1Radix): New function. (t1_toint): Use it to handle numbers in radix format. * src/psaux/t1decode.c (T1_Decoder_Parse_Charstrings): Add dummy for undocumented, obsolete opcode 15. 2002-05-21 David Turner <david@freetype.org> * src/bdf/bdflib.c: Removed compiler warning, and changed all tables to the `static const' storage specifier (instead of simply `static'). * src/type42/t42drivr.c (hexval): Use more efficient code. Removing compiler warnings. * src/bdf/bdfdrivr.c: Removing compiler warnings. * include/freetype/internal/ftbdf.h, src/base/ftbdf.c, src/base/descrip.mms, src/base/Jamfile, src/base/rules.mk (FT_Get_BDF_Charset_ID): New API to retrieve BDF-specific strings from a face.

It has been never used. 2002-05-21 Roberto Alameda <ojancano@geekmail.de>. * src/type42/t42drivr.c: s/T42_ENCODING_TYPE_/T1_ENCODING_TYPE_/. (parse_font_matrix): Remove unnecessary code. (parse_sfnts): Initialize some variables. (t42_driver_class) [TT_CONFIG_OPTION_BYTECODE_INTERPRETER]: Use ft_module_driver_has_hinter conditionally.

(VERSION_PATCH): Set to 0. * builds/toplevel.mk (dist): Ignore more git-related files. 2021-07-17 David Turner <david@freetype.org> * src/smooth/ftgrays.c: Fix compilation if `FT_LONG64` is undefined. The code assumed that if `__SSE2__` is defined, then 64-bit integer types are available. This is not the case apparently for certain multilib compiler targets like 'x86_32.x86' used by Gentoo. This patch fixes the issue by disabling the special code path when 64-bit integer types are not available. Fixes #1071. 2021-07-16 Alex Richardson <Alexander.Richardson@cl.cam.ac.uk> [tests] Allow arbitrary build directories. * tests/issue-1063/main.c (main): I am building with a build directory that is not directly inside the source tree, so the path `../tests/data/As.I.Lay.Dying.ttf` does not resolve to the test input file. This change passes the test data directory as an environment variable to allow arbitrary build directories. * tests/meson.build: Updated. 2021-07-16 Alex Richardson <Alexander.Richardson@cl.cam.ac.uk> * tests/issue-1063/main.c (main): Fix uninitialized variable. I tried running `meson test` but the test just crashed and gdb reported that the face argument to `FT_Get_Char_Index` was nonsense. With this change the test prints 'Could not open file: ' as it should. 2021-07-16 Werner Lemberg <wl@gnu.org> [smooth] Minor fixes. * src/smooth/ftgrays.c (gray_render_conic): Move variable and structure declarations to beginning of function. Inspite of C99 compliance we still do this for the sake of backward compatibility. This also avoids a shadowing declaration of `count`. (gray_convert_glyph_inner): Fix typo. 2021-07-15 Ben Wagner <bungeman@chromium.org> * src/smooth/ftgrays.c: Guard inclusion of `emmintrin.h`. Guard inclusion of `emmintrin.h` with `#ifdef __SSE2__`. The gcc version of this header, `xmmintrin.h`, and `mmintrin.h` check that the appropriate defines are set before defining anything (are internally guarded). However, the clang versions of these includes are not internally guarded. As a result of this, externally guard the inclusion of these headers. 2021-07-15 David Turner <david@freetype.org> [smooth] Implement Bézier quadratic arc flattening with DDA. Benchmarking shows that this provides a very slighty performance boost when rendering fonts with lots of quadratic Bézier arcs, compared to the recursive arc splitting, but only when SSE2 is available, or on 64-bit CPUs.

This speeds up the smooth rasterizer by avoiding conditional branches in the hot path. - Define a fixed 'null cell', which will be pointed to whenever the current cell is outside of the current target region. This avoids a `ras.cell != NULL` check in the `FT_INTEGRATE` macro. - Also use the null cell as a sentinel at the end of all `ycells` linked-lists, by setting its x coordinate to `INT_MAX`. This avoids a `if (!cell)` check in `gray_set_cell` as well. - Slightly change the worker struct fields to perform a little less operations during rendering.

(gray_dump_cells, gray_set_cell, gray_sweep, gray_sweep_direct, gray_convert_glyph_inner, gray_convert_glyph): Updated. 2021-07-15 David Turner <david@freetype.org> [tests] Rewrite download script in Python3. This commit replaces the bash script with a Python script that does the same work, plus avoiding to download anything if the files are already installed with the right content. We now use the first 8 bytes of each file's sha256 hash for the digest. * tests/scripts/download-test-fonts.sh: Removed. * tests/scripts/download-test-fonts.py: New script. * tests/README.md: Updated. 2021-07-15 Alex Richardson <Alexander.Richardson@cl.cam.ac.uk> Support architectures where `long` is smaller than pointers. I am currently trying to compile FreeType for CHERI-extended ISAs (CHERI-RISC-V and Arm's Morello), but I am getting compiler warnings from the `FT_UINT_TO_POINTER` macro. When compiling with the CHERI Clang compiler, not using `uinptr_t` for casts between integers an pointers results in the following `-Werror` build failures: ``` In file included from .../src/truetype/truetype.c:22: .../src/truetype/ttgload.c:1925:22: error: cast from provenance-free integer type to pointer type will give pointer that can not be dereferenced [-Werror,-Wcheri-capability-misuse] node->data = FT_UINT_TO_POINTER( glyph_index ); ^ .../include/freetype/internal/compiler-macros.h:79:34: note: expanded from macro 'FT_UINT_TO_POINTER' ``` * include/freetype/internal/compiler-macros.h (FT_UINT_TO_POINTER): The ISO C standard compliant fix for this would be to use `uintptr_t` from `stdint.h`, but I am not sure if this is supported by the minimum compiler version. Therefore, use the compiler-defined `__UINTPTR_TYPE__` macro (supported in GCC 4.6+ and Clang since about 3.0) before checking for `_WIN64` and falling back to `unsigned long`. 2021-07-13 Oleg Oshmyan <chortos@inbox.lv> [base] Fix `FT_Open_Face`'s handling of user-supplied streams. This was already true (though undocumented) most of the time, but not if `FT_NEW` inside `FT_Stream_New` failed or if the `FT_OPEN_XXX` flags were bad. Normally, `FT_Open_Face` calls `FT_Stream_New`, which returns the user-supplied stream unchanged, and in case of any subsequent error in `FT_Open_Face`, the stream is closed via `FT_Stream_Free`. Up to now, however, `FT_Stream_New` allocates a new stream even if it is already given one by the user. If this allocation fails, the user-supplied stream is not returned to `FT_Open_Face` and never closed. Moreover, the user cannot detect this situation: all they see is that `FT_Open_Face` returns `FT_Err_Out_Of_Memory`, but that can also happen after a different allocation fails within the main body of `FT_Open_Face`, when the user's stream has already been closed by `FT_Open_Face`. It is plausible that the user stream's `close` method frees memory allocated for the stream object itself, so the user cannot defensively free it upon `FT_Open_Face` failure lest it ends up doubly freed. All in all, this ends up leaking the memory/resources used by user's stream. Furthermore, `FT_Stream_New` simply returns an error if the `FT_OPEN_XXX` flags are unsupported, which can mean either an invalid combination of flags or a perfectly innocent `FT_OPEN_STREAM` on a FreeType build that lacks stream support. With this patch, the user-supplied stream is closed even in these cases, so the user can be sure that if `FT_Open_Face` failed, the stream is definitely closed. * src/base/ftobjs.c (FT_Stream_New): Don't allocate a buffer unnecessarily. Move error-handling code to make the control flow more obvious. Close user-supplied stream if the flags are unsupported. `FT_Stream_Open` always sets `pathname.pointer`, so remove the redundant (re)assignment. None of the `FT_Stream_Open...` functions uses `stream->memory`, so keep just one assignment at the end, shared among all possible control flow paths. ('Unsupported flags' that may need a stream closure can be either an invalid combination of multiple `FT_OPEN_XXX` mode flags or a clean `FT_OPEN_STREAM` flag on a FreeType build that lacks stream support.) 2021-07-13 Oleg Oshmyan <chortos@inbox.lv> [base] Reject combinations of incompatible `FT_OPEN_XXX` flags. The three modes are mutually exclusive, and the documentation of the `FT_OPEN_XXX` constants notes this. However, there was no check to validate this in the code, and the documentation on `FT_Open_Args` claimed that the corresponding bits were checked in a well-defined order, implying it was valid (if useless) to specify more than one. Ironically, this documented order did not agree with the actual code, so it could not be relied upon; hopefully, nobody did this and nobody will be hurt by the new validation. Even if multiple mode bits were allowed, they could cause memory leaks: if both `FT_OPEN_STREAM` and `stream` are set along with either `FT_OPEN_MEMORY` or `FT_OPEN_PATHNAME`, then `FT_Stream_New` allocated a new stream but `FT_Open_Face` marked it as an 'external' stream, so the stream object was never released. * src/base/ftobjs.c (FT_Stream_New): Reject incompatible `FT_OPEN_XXX` flags. 2021-07-12 Alex Richardson <Alexander.Richardson@cl.cam.ac.uk> * meson.build: Fix build for other UNIX systems (e.g., FreeBSD). Without this change the build of `unix/ftsystem.c` fails because the `ftconfig.h` header that defines macros such as `HAVE_UNISTD_H` and `HAVE_FCNTL_H` is only being generated for Linux, macOS, and Cygwin systems: ``` .../builds/unix/ftsystem.c:258:32: error: use of undeclared identifier 'O_RDONLY' file = open( filepathname, O_RDONLY ); ``` Instead of hardcoding a list of operating systems for this check, update the logic that decides whether to build the file and set a boolean flag that can be checked instead. 2021-07-12 Werner Lemberg <wl@gnu.org> [autofit] More clean-ups. * src/autofit/afhints.h (AF_GlyphHintsRec): Remove the no longer needed fields `xmin_delta` and `xmax_delta`. * src/autofit/afhints.c (af_glyph_hints_reload), src/autofit/afloader.c (af_loader_load_glyph): Updated. 2021-07-12 Werner Lemberg <wl@gnu.org> Small clean-ups for the last few commits. * include/freetype/fttrace.h (afwarp): Removed. 2021-07-12 David Turner <david@freetype.org> Remove obsolete `AF_Angle` type and related sources. * src/autofit/afangles.c: File removed. Functions related to sorting moved to... * src/autofit/afhints.c (af_sort_pos, af_sort_and_quantize_widths): This file. * src/autofit/afangles.h: File removed. * src/autofit/aftypes.h: Updated. * src/autofit/autofit.c: Updated. * src/autofit/rules.mk (AUTOF_DRV_SRC): Updated. 2021-07-12 David Turner <david@freetype.org> Remove experimental auto-hinting 'warp' mode. This feature was always experimental, and probably never worked properly. This patch completely removes it from the source code, except for a documentation block describing it for historical purposes. * devel/ftoption.h, include/freetype/config/ftoption.h: Remove `AF_CONFIG_OPTION_USE_WARPER`. * include/freetype/ftdriver.h: Document 'warping' property as obsolete. * src/autofit/afwarp.c, src/autofit/afwarp.h: Files removed. * src/autofit/: Remove any code related to warp mode. 2021-07-12 David Turner <david@freetype.org> Remove experimental 'Latin2' writing system (`FT_OPTION_AUTOFIT2`). This code has always been experimental and was never compiled anyway (`FT_OPTION_AUTOFIT2` does not appear in `ftoption.h` or even any of our build files). include/freetype/internal/fttrace.h (aflatin2): Removed. * src/autofit/aflatin2.h, src/autofit/aflatin2.c: Files removed. * src/autofit/afloader.c: Remove undocumented hook to activate Latin2 system. * src/autofit/afstyles.h: Remove `ltn2_dflt` style definition. * src/autofit/afwrtsys.h: Remove `LATIN2` writing system definition. * src/autofit/autofit.c: Updated. 2021-07-05 Werner Lemberg <wl@gnu.org> * src/base/ftlcdfil.c (FT_Library_SetLcdGeometry): Fix argument. Reported by Hin-Tak. 2021-07-03 Werner Lemberg <wl@gnu.org> * meson_options.txt: Sort alphabetically; no final full stops. 2021-07-01 Ben Wagner <bungeman@chromium.org> * src/truetype/ttgxvar.c (tt_set_mm_blend): Test `coords`. It is undefined behavior to pass `NULL` to `memcpy`. `coords' is passed to `memcpy` but `TT_Get_MM_Blend` and `TT_Get_Var_Design` explictly call `tt_set_mm_blend` with `coords` as `NULL`. In addition, `TT_Set_MM_Blend` has a similar possible issue. 2021-06-30 Dominik Röttsches <drott@chromium.org> [sfnt] Support PaintScale in 'COLR' v1 parsing. * include/freetype/ftcolor.h (FT_PaintFormat): Renumber values, add `FT_COLR_PAINTFORMAT_SCALE`. (FT_PaintScale): New structure to represent 'PaintScale' tables. (FT_COLR_Paint): Updated. src/sfnt/ttcolr.c (FT_PaintFormat_Internal): New enumeration. (read_paint): Parse 'PaintScale' and friends. 2021-06-30 Dominik Röttsches <drott@chromium.org> [sfnt] Handle fonts without layer list in 'COLR' v1. 'COLR' v1 fonts do not necessarily need to have a layer list; for this reason, 'fontTools' recently started generating fonts in a way that drops the layer list if there are no layers in it. This results in the layer list offset becoming zero, which FreeType treated as an invalid table. Fix that and handle the case for layer list offset being 0. This slightly changes how we need to calculate the starting offset for paints. * src/sfnt/ttcolr.c (tt_face_load_colr): Handle case of layer list offset being zero without outright rejecting table. 2021-06-30 Alexei Podtelezhnikov <apodtele@gmail.com> * src/raster/ftraster.c (Render_Single_Pass): Simplify `band_stack'. 2021-06-29 Alexei Podtelezhnikov <apodtele@gmail.com> [raster] Do not skip the second pass without dropout control. The second pass also fixes horizontal lines through the pixel centers. * src/raster/ftraster.c (black_TWorker): Do not use `second_pass'. (Render_Glyph): Skip the second pass only with the appropriate flag. 2021-06-29 Alexei Podtelezhnikov <apodtele@gmail.com> [raster] Handle sub-band stack locally. * src/raster/ftraster.c (black_TWorker): Move `band_stack' from here.. (Render_Single_Pass): ... to here and accept limit arguments. (Render_Glyph): Updated. 2021-06-25 Anurag Thakur <anuthadev@gmail.com> [CI] Introduce linux CI and refactor job names. * .gitlab-ci.yml: Added jobs for building freetype on linux. 2021-06-28 Alexei Podtelezhnikov <apodtele@gmail.com> [raster] Handle Bézier stack locally. * src/raster/ftraster.c (black_TWorker): Move `arcs' from here... (Conic_To, Cubic_To): ... to here to tighten their scope. (Bezier_Up, Bezier_Down): ... Take the current `arc' argument. 2021-06-28 Dominik Röttsches <drott@chromium.org> [sfnt] Improve paint limit checks Paint tables can appear before the `base_glyphs_v1` offset if the font is produced with the layer list before the base glyph list. In this case paint tables can occur after the layer list but before the base glyph list. Checks in the 'COLR' v1 code were rejecting fonts with this layout. Improve these checks by calculating a minimum offset after which paint tables can occur and use that in safety checks. * src/sfnt/ttcolr.c (Colr, tt_face_load_colr): Declare `paint_start_v1` and calculate that as the minimum of the end of layer list and base glyph list. (get_child_table_pointer, read_paint, tt_face_get_paint_layers): Use that in safety checks. 2021-06-28 Alexei Podtelezhnikov <apodtele@gmail.com> [raster] Clean up vertical sweep. * src/raster/ftraster.c (black_TWorker): Replace the current line offset with the pointer and drop the increment. (Function_Sweep_Init): Take values as arguments instead of pointers. (Vertical_Sweep_, Horizontal_Sweep_Init, Draw_Sweep): Updated. 2021-06-25 Alexei Podtelezhnikov <apodtele@gmail.com> [raster] Make `band_top' local variable. src/raster/ftraster.c (black_TWorker): Move `band_top' from here... (Render_Single_Pass): ... to here, and refactor. (Render_Glyph): Updated. 2021-06-25 Alexei Podtelezhnikov <apodtele@gmail.com> [raster] Adjust sub-band bisecting limits. We can bisect a band until it is just a single scan line. This might be slow and cause time-outs but if we need to impose limits it should be elsewhere. * src/raster/ftraster.c (Render_Single_Pass): Tweak sub-banding. 2021-06-25 Alexei Podtelezhnikov <apodtele@gmail.com> * src/raster/ftraster.c (Render_Single_Pass): Remove dead code. 2021-06-25 Werner Lemberg <wl@gnu.org> [base] Add trace level to logging output. Some practical debugging work has shown that displaying level X of an `FT_TRACEX` macro in the output of `FT2_DEBUG="... -v"` would be very helpful to find out which trace level should be selected. As an example, we now get output like ``` [ttobjs:2] TTF driver [ttobjs:2] SFNT driver [sfobjs:2] not a font using the SFNT container format [t1objs:2] Type 1 driver [stream:7] FT_Stream_EnterFrame: 14 bytes ``` * include/freetype/internal/ftdebug.h (FT_LOGGING_TAGX): New macro. (FT_LOG): Use it to add the trace level to the logging tag. * include/freetype/internal/fttrace.h (FT_MAX_TRACE_LEVEL_LENGTH): Adjust. * docs/DEBUG: Updated. 2021-06-24 Alexei Podtelezhnikov <apodtele@gmail.com> [smooth, raster] Fix up and align error codes. FT_Render_Glyph picked up FAILURE or 1 returned from the raster function, which became a confusing error code. Instead, return Raster_Overflow in the unlikely event that banding does not help or another meaningful error. * src/smooth/ftgrays.c (gray_convert_glyph_inner, gray_convert_glyph): Use Raster_Overflow when the rendering pool is exhausted and return it if banding does not help. (gray_raster_render): Use Smooth_Err_Ok. * src/raster/ftraster.c (Render_Single_Pass): Return Raster_Overflow if banding does not help or another error code. 2021-06-23 Alexei Podtelezhnikov <apodtele@gmail.com> [smooth, raster] Remove synonymous error macros. * src/smooth/ftgays.c [STANDALONE_]: s/ErrRaster_/Smooth_Err_/. (gray_convert_glyph_inner): Updated accordingly. * src/raster/ftraster.c [STANDALONE_]: Do not abbreviate error macros. (New_Profile, End_Profile, Insert_Y_Turn, Line_Up, Bezier_Up, Decompose_Curve, Draw_Sweep, Render_Single_Pass, ft_black_render): Updated accordingly. 2021-06-22 Dominik Röttsches <drott@chromium.org> [sfnt] s/PaintTransformed/PaintTransform/, s/transformed/transform/. * include/freetype/ftcolor.h (FT_PaintTransformed, FT_PaintFormat, FT_COLR_Paint): Do it to make it harmonize with other names such as 'PaintTranslate'. * src/sfnt/ttcolr.c (read_paint, tt_face_get_paint): Ditto. 2021-06-22 Dominik Röttsches <drott@chromium.org> Move 'COLR' API to `ftcolor.h`. * include/freetype/freetype.h: Cut section layer managament containing 'COLR' v0 and v1 API and move it to `ftcolor.h` as requested by Werner on freetype-devel. * include/freetype/ftcolor.h: Paste that section. 2021-06-19 Werner Lemberg <david@freetype.org> [truetype] Fix integer overflow.

While looping to `Again`, the next operation is successful, but -1 is still returned by the function. The fix is to set `error` to 0 appropriately. Fixes #1063. 2021-06-15 David Turner <david@freetype.org> [meson] Add first regression test to FreeType. * tests/README.md: New file that explains how to build and run the tests with the Meson build. * tests/scripts/download-test-fonts.sh: New bash script to download test font files to the `tests/data` folder. * meson.build, meson_options.txt: Add 'tests' option to enable building and running the test programs (disabled by default). * tests/meson.build: New file. * tests/issue-1063/main.c: Simple regression test to exhibit issue 1063. * .gitignore: Ignore the content of the `tests/data` folder for now. 2021-06-12 Alexei Podtelezhnikov <apodtele@gmail.com> [type42] Fix new memory leak. We need to inverse inheritance of FT_GlyphSlot_Internal so that we have a chance to free the rendered bitmap from the parent slot. * src/type42/t42objs.c (T42_GlyphSlot_Init): Remove the internal parts of the child `ttslot' and replace it with the parent structure.

Since 8-bits is enough to represent SDF data we no longer require 16-bits for this purpose. Also, we now normalize the output data to use the entire 8-bit range efficiently. For example: if we use 3.5 format with a spread of 1 we basically only use the starting 5-bits. By normalizing we can use the entire 8-bit range. * include/freetype/freetype.h (FT_Render_Mode): Updated description for `FT_RENDER_MODE_SDF` regarding this change. * include/freetype/ftimage.h (FT_Pixel_Mode): Removed `FT_PIXEL_MODE_GRAY16` since no longer required. * include/freetype/fttypes.h (FT_F6Dot10): Removed since no longer required. * src/sdf/ftsdfrend.c (ft_sdf_render, ft_bsdf_render): Allocate 8-bit bitmap instead of 16-bit buffer. * src/sdf/ftsdfcommon.h (map_fixed_to_sdf): Added function to convert 16.16 distance value to our desired format. * src/sdf/ftsdf.c (sdf_generate_with_overlaps, sdf_generate_bounding_box): Use the new `map_fixed_to_sdf` function and also use 8-bit output buffer. * src/sdf/ftbsdf.c (finalize_sdf): Output to a 8-bit buffer instead of 16-bit buffer. 2021-06-02 Ben Wagner <bungeman@chromium.org> Werner Lemberg <wl@gnu.org> [sfnt] Fix fallout from 2021-05-29 change. * src/sfnt/ttcolr.c (find_base_glyph_record, find_base_glyph_v1_record): Adjust binary search.

While a function pointer may be cast to another function pointer type, it is required to cast the function pointer back to the original function pointer type before calling it. If a parameter is a pointer the exact pointer type is required. Using a pointer to a different underlying type is technically undefined behavior. The wrapper functions `ft_gzip_alloc` and `ft_gzip_free` took `FT_Memory` (a `FT_MemoryRec_`) instead of `voidpf` (`void`), so when gzip calls these callbacks through `alloc_func` or `free_func` it invokes undefined behavior. On most platforms this works out as expected, but newer undefined behavior detectors and targets like wasm can detect this and will produce an error. * src/gzip/ftgzip.c (ft_gzip_alloc, ft_gzip_free): Update signatures to exactly match `alloc_func` and `free_func`, respectively. Internally, cast the `void` opaque pointer to `FT_Memory`. 2021-05-18 Alexei Podtelezhnikov <apodtele@gmail.com> Prioritize the anti-aliasing renderer module. modules.cfg: Reorder the renderers. * include/freetype/config/ftmodule.h: Ditto. 2021-05-16 Alexei Podtelezhnikov <apodtele@gmail.com> [sfnt] Additional guards on the POST table.

However, it was not resetting the values of the advances and `glyph_index`. Reset the advances and `glyph_index` to zero. 2021-04-02 Ben Wagner <bungeman@chromium.org> [truetype] Prevent glyph program state from persisting. `FDEF` instructions are specified as allowed only in 'prep' or 'fpgm'. FreeType has attempted to prevent their use in the glyph program, but they were still allowed in glyph programs if defined in a function defined in 'prep' or 'fpgm' and called from the glyph program. Similarly, `IDEF` instructions are specified not to be able to modify any existing instruction. FreeType has attempted to prevent their use in the glyph program, but they can still be used like `FDEF`. This change stores the initial bytecode range type and disallows the use of `FDEF` and `IDEF` while running the glyph program. Most other state is copied from the `TT_Size` into the execution context. However, it is possible for a glyph program to use `WS` to write to the storage area or `WCVTP`, `WCVTF`, and `DELTAC[123]` to write to the control value table. Allowing any change to the global state from the glyph program is problematic as the outlines of any given glyph may change based on the order the glyphs are loaded or even how many times they are loaded. There exist fonts that write to the storage area or the control value table in the glyph program, so their use should not be an error. Possible solutions to using these in the glyph program are * ignore the writes; * value-level copy on write, discard modified values when finished; * array-level copy on write, discard the copy when finished; * array-level copy up-front. Ignoring the writes may break otherwise good uses. A full copy up-front was implemented, but was quite heavy as even well behaved fonts required a full copy and the memory management that goes along with it. Value-level copy on write could use less memory but requires a great deal more record keeping and complexity. This change implements array-level copy on write. If any attempt is made to write to the control value table or the storage area when the initial bytecode range was in a glyph program, the relevant array will be copied to a designated storage area and the copy used for the rest of the glyph program's execution. * src/truetype/ttinterp.h (TT_ExecContextRec): New fields `iniRange`, `glyfCvtSize`, `glyfCvt`, `origCvt`, `glyfStoreSize`, `glyfStorage`, and `origStorage`. * src/truetype/ttinterp.c (Modify_CVT_Check): New function to handle `exc->glyfCvt`.

(read_paint): Initialize and track status of insert_root_transform flag. 2021-02-09 Xavier Claessens <xavier.claessens@collabora.com> * meson.build: s/freetype2_dep/freetype_dep/. Many projects (e.g., fontconfig, cairo) hardcode the `freetype_dep` variable name to use FreeType as subproject because that was the variable name in Centricular's Meson port of FreeType. While they should stop hardcoding that variable name, it does not cost us anything to keep using that name to ease transition. 2021-02-09 Xavier Claessens <xavier.claessens@collabora.com> [meson] Fix handling of HarfBuzz library. * meson.build (harfbuzz_dep): Do not fall back to HarfBuzz by default. Otherwise it causes a dependency cycle: cairo => fontconfig => freetype2 => harfbuzz => cairo Meson will still fall back to HarfBuzz subprojects if the `harfbuzz` option is set to `enabled` instead of `auto` and a `subprojects/harfbuzz.wrap` file is present. In that case it is the responsibility of the main project to set the proper options on each subproject to break the dependency cycle. Fixes: #1028. 2021-02-09 Xavier Claessens <xavier.claessens@collabora.com> [meson] Fix dependency lookup and generate `ftconfig.h`. - zlib: If not found on the system, meson can build it as a subproject. We thus never use the (outdated) zlib support that comes with FreeType. Doing so has the additional advantage that the zlib code can be shared with other projects like GLib if both are subprojects of an application. - harfbuzz: Build as a subproject if not found on the system. - 'QUESTION: What if the compiler doesn't support `-D` but uses `/D` instead as on Windows?' Answer: Meson translate arguments for us. - visibility: Replace self-made code with meson-specific solution. * meson.build (ft2_defines): Rewrite logic to set and handle it. (process_header_command): New variable, previously called `ftoption_command`. (ftoption_command, ftconfig_command): New variables. (zlib_option): Removed. (zlib_dep): New variable. (ft2_deps): Updated. (harfbuzz_dep): Updated. (ftconfig_h_in, ftconfig_h): New variables. (ft2_sources): Updated. (ft2_lib): Updated, handle visibility.

This is copied from GStreamer's meson port of FreeType. (ft2_sources): Add both debug and resource file (the latter for Windows only). (ft2_debug_src): Removed. 2021-02-09 Xavier Claessens <xavier.claessens@collabora.com> * meson.build: s/ft2_libtool_version/ft2_pkgconfig_version/. (freetype2_dep): Use it. `ft2_libtool_version` would be the shared library version, not the one we should use in file `freetype2.pc`. 2021-02-09 Xavier Claessens <xavier.claessens@collabora.com> * meson.build: Use `meson.override_dependency`. This is a new meson mechanism to avoid other projects to hard-code the `freetype2_dep` variable name in their build definition. It also ensures that meson does not mix system and subproject versions of FreeType inside of the same project. Also remove outdated TODO because `declare_dependency` was already there. 2021-02-09 Xavier Claessens <xavier.claessens@collabora.com> * meson.build (bzip2_dep): Simplify. We remove `static:false` from `find_library('bz2')`. I don't know whether the previous code was a workaround for an old meson bug, but at least with version >=0.55.0 (which FreeType uses) it picks the shared library when both are available. File `freetype2.pc` still contains the full path to file `libbz2.so` instead of `-lbz2` – that we need to do this is a meson bug even present in the current version (0.57.0). 2021-02-09 Xavier Claessens <xavier.claessens@collabora.com> * meson.build: Set project version. 2021-02-04 Werner Lemberg <wl@gnu.org> [base] Fix Netpbm tracing message. * src/base/ftobjs.c (FT_Render_Glyph_Internal): Don't emit Netpbm warning if there is nothing to output. 2021-02-04 Werner Lemberg <wl@gnu.org> * src/: Don't use more than one '\n' in `FT_TRACE` and `FT_ERROR`. This ensures good logging output, with all lines having a proper prefix (if requested).

The forthcoming 'bsdf' renderer will require bitmaps for processing. * src/base/ftobjs.c (ft_add_renderer, ft_remove_renderer): Remove renderer's glyph format check before adding and removing them. The 'bsdf' renderer will have a format `FT_GLYPH_FORMAT_BITMAP`. 2020-08-16 Anuj Verma <anujv@iitbhilai.ac.in> Add data types required for the forthcoming 'sdf' module. * include/freetype/freetype.h (FT_Render_Mode): Add new render mode `FT_RENDER_MODE_SDF`, which will be used to generate SDF. * include/freetype/ftimage.h (FT_Pixel_Mode): Add new pixel mode `FT_PIXEL_MODE_GRAY16`, which will be the output of the 'sdf' module.

The old code used to divide the darkening amount by em_ratio twice, leading to unnecessarily bold stems on certain fonts with higher units per em (e.g. Inter). This patch fixes it. The return value of af_loader_compute_darkening was also changed to use 16.16 fixed point to get rid of a redundant truncation operation. This should slightly improve the precision, although it's still bottlenecked by the emboldening function, which uses 26.6 fixed point. * src/autofit/afloader.[ch] (af_loader_compute_darkening): Return FT_Fixed.

For formats like PCL XL format 1, class 2 downloaded fonts (where metrics are removed from the TTF header), this causes problems when the hinting program uses the phantom points (misplaced and distorted glyphs) due to the metrics being unset (all zeros). (tt_get_metrics_incr_overrides): Renamed to... (tt_get_metrics_incremental): ... this. Updated caller * include/freetype/ftincrem.h: Update the documentation to make it clearer that `get_glyph_metrics` is to retrieve metrics from a non-standard source, but not for the purpose of imposing custom metrics. 2020-12-14 Werner Lemberg <wl@gnu.org> [type42] Pacify static analysis tools (#59682). * src/type42/t42objs.c (T42_Size_Init, T42_GlyphSlot_Init): Avoid warnings about uninitialized variables. 2020-12-07 Werner Lemberg <wl@gnu.org> * builds/unix/configure.raw: Don't set `FT_DEBUG_LOGGING`.

Add `DLG_STATIC' for 'Debug' configuration on 'x64' and 'win32' platforms. (DisableLanguageExtensions): We need to disable the `/Za` option when building 'dlg' with FreeType as 'dlg' strictly follows the C99 standard. Visual C++ produces behaves unexpectedly when compiling a C99 file with `/Za` option enabled. 2020-11-30 Priyesh Kumar <priyeshkkumar@gmail.com> [base] Add public API to change log handling function. * include/freetype/ftlogging.h (FT_Custom_Log_Handler): New function typedef to store the custom callback logging function.

This corresponds to the following commits in the ttfautohint git repository: bb6842bd3bd437b7b4a7921b0376c860f5e73d18 Typo, formatting. d5c91ddb1cb310257a3dfe9a8e20e1fc51335faa Add Medefaidrin script. * src/autofit/afblue.dat: Add blue zone data for Medefaidrin. * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated. * src/autofit/afscript.h: Add Medefaidrin standard characters. * src/autofit/afranges.c, src/autofit/afstyles.h: Add Medefaidrin data. 2020-09-25 Werner Lemberg <wl@gnu.org> Move `scripts/make_distribution_archives.py` to `src/tools`. * scr/tools/scripts/make_distribution_archives.py: (_TOP_DIR, _SCRIPT_DIR): Updated to new location. (main): s/shutils.copyfile/shutils.copy/ to preserve file permissions. (main): Prefix source file paths with `git_dir` while copying files to allow calls of the script from other places than the top-level directory. 2020-09-24 Werner Lemberg <wl@gnu.org> * src/cff/cffgload.c (cff_slot_load): Scale `vertBearingY`. Towards the end of the the function there is a call to `FT_Outline_Get_CBox` that retrieves the glyph bbox in scaled units. That sets `horiBearing{X,Y}` and `vertBearingX` but `vertBearingY` is left alone, and is not scaled. Patch from Eric Muller <emuller@amazon.com>. 2020-09-24 Werner Lemberg <wl@gnu.org> * src/base/ftobjs.c (FT_Load_Glyph): Trace glyph metrics. 2020-09-22 Werner Lemberg <wl@gnu.org> [meson] Move auxiliary scripts to `builds/meson`. Suggested by Alexei. * scripts/.py: Move meson scripts to... builds/meson/.py: ... this new location. meson.build: Updated. 2020-09-21 David Turner <david@freetype.org> Add python script for building tarballs. * scripts/make_distribution_archives.py: New file. This standalone Python script should be equivalent to running `make dist` with the Make-based build system, with the following minor differences: - Since `make distclean` doesn't always clean up `objs/` properly, `make dist` archives may contain some stale binaries like `objs/.libs/libfreetype.so.6` or others. - `config.guess` and `config.sub` are not updated unless option `--gnu-config-dir=DIR` is used to specify the location of these files. - Some bits of the auto-generated reference documentation may appear in slightly different order, probably due to issues related to mkdocs and docwriter. As an example, the call scripts/make_distribution_archives.py /tmp/freetype2-dist creates the following files under `/tmp/freetype2-dist`: freetype-<version>.tar.gz freetype-<version>.tar.xz ft<winversion>.zip 2020-09-21 Werner Lemberg <wl@gnu.org> * scripts/extract_freetype_version.py: Fix regex typos. 2020-09-21 David Turner <david@freetype.org> Add Meson build project file. Example usage: # Configure Meson build in directory `build-meson` to generate # release binaries comparable to to the ones from the # autotools/make build system. meson setup build-meson \ --prefix=/usr/local \ --buildtype=debugoptimized \ --strip \ -Db_ndebug=true # After configuring the Meson build with the above command, # compile and install to `/usr/local/`; this includes a pkg-config # file. ninja -C build-meson install # Alternatively, compile and install to `/tmp/aa/usr/local/...` # for packaging. DESTDIR=/tmp/aa ninja -C build-meson install # Generate documentation under `build-meson/docs`. ninja -C build-meson docs Library size comparison for stripped `libfreetype.so` generated by all three build systems: - Default build (autotools + libtool): 712 KiB - CMake build (RelWithDebInfo): 712 KiB - Meson build: 712 KiB * meson.build: New top-level Meson build file for the library. * meson_options.txt: New file. It holds user-selectable options for the build, which can be printed with `meson configure`, and selected at `meson setup` or `meson --reconfigure` time with `-D<option>=<value>`. * scripts/parse_modules_cfg.py: A script invoked by `meson.build` to parse `modules.cfg` and extract important information out of it (i.e., the list of modules). * scripts/process_ftoption_h.py: New script invoked by `meson.build` to process the original `ftoption.h` file. It enables or disables configuration macro variables based on the available dependencies. This is similar to what other build systems are using (i.e., Meson's `configure_file()` command is not used here). * scripts/extract_freetype_version.py: New script invoked by `meson.build` to extract the FreeType version number from `<freetype/freetype.h>`. * scripts/extract_libtool_version.py: New script invoked by `meson.build` to extract the libtool `revision_info` data from `builds/unix/configure.raw`, and to generate the corresponding shared library suffix. * scripts/generate_reference_docs.py: New script invoked by `meson.build` to generate the FreeType 2 reference documentation (using the `docwriter` and `mkdocs` packages, which must be already installed). 2020-09-11 Alexei Podtelezhnikov <apodtele@gmail.com> [raster] Improve the second pass (#58373). Besides dropout control the second horizontal sweep is supposed to clean up straight horizontal edges that are mishandled by the first vertical sweep when a line passes through pixel centers. This line would present as perfectly aligned span edges in the second sweep. * src/raster/ftraster.c (Horizontal_Sweep_Span): Replace the old implementation with a better one focusing on aligned span edges only. 2020-09-08 Alexei Podtelezhnikov <apodtele@gmail.com> [raster] Tune SMART macro (#58352). Windows seems to perform smart dropout control at 26.6 precision. To mimick Windows independent of increased precision, we need to tweak the macro so that some close calls break down rather than up. * src/raster/ftraster.c (SMART): Tweak the macro. 2020-09-08 Alexei Podtelezhnikov <apodtele@gmail.com> [raster] Introduce SMART macro. * src/raster/ftraster.c (SMART): New macro for smart dropout rounding.

The following builds were still failing due to previous changes: make multi make multi CC="c++" make CC="c++" This patch fixes the issues, which were missing includes to get the right macro definitions in multi-build mode. Also, `FT_UNUSED' is actually used by third-party code, so move it back to `public-macros.h' to avoid breaking it. * include/freetype/config/public-macros.h (FT_EXPORT): Remove special definition for C++.

(FT_EXPORT): Use it. * include/freetype/config/compiler-macros.h (FT_INTERNAL_FUNCTION_ATTRIBUTE): New macro to tag functions as internal to the library (and thus hidden). Note that on ELF systems, all internal functions have hidden visibility, which avoids the need to enforce this when invoking the compiler (e.g., with an option like `-fvisibility=hidden'). (FT_FUNCTION_DECLARATION, FT_FUNCTION_DEFINITION): New base macros to deal with C and C++ linkage issues at the same time. (FT_LOCAL, FT_LOCAL_DEF, FT_LOCAL_ARRAY, FT_LOCAL_ARRAY_DEF, FT_BASE, FT_BASE_DEF, FT_EXPORT_VAR, FT_BASE_CALLBACK, FT_BASE_CALLBACK_DEF): Redefined using new macros. 2020-07-05 David Turner <david@freetype.org> [build] Split off more stuff from `ftconfig.h'. * builds/unix/ftconfig.h.in, builds/vms/ftconfig.h, include/freetype/config/ftconfig.h: Split off macro definitions required by the FreeType API headers to... * include/freetype/config/public-macros.h: ...this new file. * builds/unix/ftconfig.h.in, builds/vms/ftconfig.h, include/freetype/config/ftconfig.h: Split off macro definitions used by the library but not to be exposed to clients to... * include/freetype/config/compiler-macros.h: ...this new file. * include/freetype/internal/.h, src/raster/ftraster.h: Include `compiler-macros.h' where needed. 2020-07-05 David Turner <david@freetype.org> [build] Move mac support code to `mac-support.h'. builds/unix/ftconfig.h.in, builds/vms/ftconfig.h, include/freetype/config/ftconfig.h: Split off mac-specific stuff to... * include/freetype/config/mac-support.h: ...this new file. * CMakeLists.txt, builds/unix/configure.raw: Remove `/undef -> #undef' string replacement; the affected code is no longer part of the `ftconfig.h' template. 2020-07-05 David Turner <david@freetype.org> [build] Put integer type definitions into `integer-types.h'. Refactor some of the `ftconfig.h' headers and template to move the definition of the FreeType integer types (e.g., `FT_Int16') to a common header file `freetype/config/integer-types.h'. * builds/unix/ftconfig.h.in, builds/vms/ftconfig.h, include/freetype/config/ftconfig.h: Split off integer type definition stuff to... * include/freetype/config/integer-types.h: ...this new file. * builds/unix/ftconfig.h.in: Control the definition of `FT_SIZEOF_INT' and `FT_SIZEOF_LONG' with macro `FT_USE_AUTOCONF_SIZEOF_TYPES'. If these are not defined, auto detection happens in `integer-types.h' as usual based on `INTXX_MAX' values. Otherwise the autoconf-detected values are used. * builds/unix/configure.raw (CPPFLAGS): Don't include path to `config' directory. Instead, ... (FT_CONFIG_STANDARD_LIBRARY_H): Use complete path. 2020-07-05 David Turner <david@freetype.org> [build] Rename `build/unix/ftconfig.in' to `ftconfig.h.in'. Since we are no longer limited to 8.3 file names, it is simpler to follow the usual conventions for template files. * builds/unix/ftconfig.in: Renamed to... * builds/unix/ftconfig.h.in: ...this. * CMakeLists.txt, builds/unix/configure.raw: Updated. 2020-07-03 Alexei Podtelezhnikov <apodtele@gmail.com> [smooth] Introduce direct oversampling for overlaps. This implements oversampling to mitigate artifacts in pixels partially covered by overlapping contours. It turns out that the 4x4 oversampling is sufficient but, at least, quadruples the rendering time. The outline has to set FT_OUTLINE_OVERLAP to use this method. * include/freetype/ftimage.h (FT_OUTLINE_OVERLAP): New flag. * src/smooth/ftsmooth.c (ft_smooth_render): Check it to... (ft_smooth_raster_overlap): ... inflate outline and set up direct rendering for oversampling with... (ft_smooth_overlap_spans): ... new span function that integrates them. 2020-07-03 Alexei Podtelezhnikov <apodtele@gmail.com> [smooth] Use direct rendering mode in Harmony. Instead of rendering 3 bitmaps side by side and reshuffling, we use direct rendering to deliver the bitmaps on each third byte. * src/smooth/ftsmooth.c (ft_smooth_raster_lcd) [!FT_CONFIG_OPTION_SUBPIXEL_RENDERING]: Set up direct mode with... (ft_smooth_lcd_spans): ... new span function. 2020-07-03 Alexei Podtelezhnikov <apodtele@gmail.com> [smooth] Separate LCD paths from gray rendering. This makes `ft_smooth_render' a lot smaller and easier to follow. It also cleanly separates Harmony and ClearType-style LCD rendering algorithms. Now I only wish to move LCD filtering and geometry from FT_Library to FT_Renderer. * src/smooth/ftsmooth.c (ft_smooth_render): Move LCD code from here... (ft_smooth_raster_lcd, ft_smooth_raster_lcdv): ... to here.

Do the same for both allocations if there is a later error. 2020-06-13 Werner Lemberg <wl@gnu.org> Remove redundant inclusion of `ft2build.h'. * /: Remove `#include <ft2build.h>' where possible. * include/freetype/freetype.h: Remove cpp error about missing inclusion of `ft2build.h'. 2020-06-08 David Turner <david@freetype.org> Make macros for header file names optional. We no longer have to take care of the 8.3 file name limit; this allows us (a) to introduce longer, meaningful file names, and (b) to avoid macro names in `#include' lines altogether since some compilers (most notably Visual C++) doesn't support this properly. /: Replace #include FOO_H with #include <freetype/foo.h> or something similar. Also update the documentation. 2020-06-02 Werner Lemberg <wl@gnu.org> * src/sfnt/ttcmap.c (tt_face_build_cmaps): Trace number of cmaps. 2020-05-18 David Turner <david@freetype.org> Remove obsolete HAVE_STDINT_H probing macro. This macro was updated by the unix configure script and the `CMakeLists.txt' one, but is never used in the source tree (nor is <stdint.h> included anywhere). * CMakeLists.txt, builds/unix/ftconfig.in: Don't handle `HAVE_STDINT_H'. 2020-05-18 David Turner <david@freetype.org> Remove Jamfile files from the tree.

A corresponding patch will be submitted to the `freetype2-demos' repository. * src/Jamfile, src//Jamfile, Jamrules: Delete. 2020-05-12 Alexei Podtelezhnikov <apodtele@gmail.com> [smooth] Turn on LCD filtering during FreeType initialization. src/smooth/ftsmooth.c (ft_smooth_init): Enable LCD filtering. * include/freetype/ftlcdfil.h: Document it, remove patent warnings. * include/freetype/freetype.h (FT_Render_Mode): Updated. * include/freetype/config/ftoption.h, devel/ftoption.h [FT_CONFIG_OPTION_SUBPIXEL_RENDERING]: Do not mention patents. 2020-05-11 Alexei Podtelezhnikov <apodtele@gmail.com> [smooth] Stop using dedicated LCD modules and classes. The LCD modules were never truly independent. They mostly served as a way to disable patented LCD rendering, which is no longer necessary. The `smooth' module now handles LCD modes as well. * src/smooth/ftsmooth.c (ft_smooth_lcd_renderer_class. ft_smooth_lcdv_renderer_class): Deleted.

In order to support `gzip' encoded header the call to `inflateInit2' was modified in commit 6a92b1fadde26477a9179. However, this code breaks with the outdated internal version of zlib. This is a temporary fix to conditionally support `gzip' encoded header whenever a system installation of zlib is being used.

By resetting the blend as implemented with this commit fonts with invalid `gvar' tables may keep calling into `ft_var_load_gvar' from `tt_set_mm_blend' and failing, but the font was invalid anyway and we want to keep seeing the failure in `tt_set_mm_blend'. * src/truetype/ttgxvar.c (ft_var_load_gvar): Calculate length of offset array once. Allocate arrays after `FT_FRAME_ENTER' (extra check before allocating and avoid needing to free array later if error entering frame). Always call `FT_FRAME_EXIT'. Consistently set counts immediately after array initialized. Reset the blend (particularly `blend->glyphoffsets') on failure. 2020-03-01 Nikhil Ramakrishnan <ramakrishnan.nikhil@gmail.com> [docs] Update docwriter stylesheet.

The libs which cmake controls are commented out at include/freetype/config/ftoption.h and cmake un-comment each enabled library, but the brotli option was not commented out, therefore `FT_CONFIG_OPTION_USE_BROTLI' remained defined even if brotli was missing/disabled/etc. Comment it such that cmake can control it, which means leaving it undefined if brotli is missing. * include/freetype/config/ftoption.h: Fix typo. 2019-09-05 Werner Lemberg <wl@gnu.org> [cmake] Add brotli support. * CMakeLists.txt (FT_WITH_BROTLI): New option. * builds/cmake/FindBrotliDec.cmake: New file. 2019-09-05 Werner Lemberg <wl@gnu.org> Fix handling of `AF_CONFIG_OPTION_INDIC'. * devel/ftoption.h, include/freetype/config/ftoption.h: `AF_CONFIG_OPTION_INDIC' needs `AF_CONFIG_OPTION_CJK'. 2019-09-05 Werner Lemberg <wl@gnu.org> CMakeLists.txt: Fix generation of DLL related stuff (#56852). Extract `version_info' variable from `builds/unix/configure.raw' and use the data to correctly set `LIBRARY_VERSION' and `LIBRARY_SOVERSION'. Also use the data to set `ft_version' field in `freetype2.pc'. Also fix the needed minimum version of HarfBuzz in `freetype2.pc'. 2019-09-03 Werner Lemberg <wl@gnu.org> * src/sfnt/sfwoff2.c (compute_ULong_sum): Fix undefined shift.

Adjust tracing levels for comments, and more formatting. 2019-08-27 Nikhil Ramakrishnan <ramakrishnan.nikhil@gmail.com> [woff2] Support `hmtx' reconstruction when `glyf' is untransformed. `reconstruct_hmtx' requires `info->x_mins' and `info->num_glyphs' to reconstruct the hmtx table. In case glyf is not transformed, we call `get_x_mins' which does the necessary work. * src/sfnt/sfwoff2.c (get_x_mins): New function. (reconstruct_font): Call get_x_mins. 2019-08-27 Nikhil Ramakrishnan <ramakrishnan.nikhil@gmail.com> [sfnt] Support `face->num_faces' for WOFF2 fonts. Set correct value of `face->num_faces' for WOFF2 fonts. This is being handled separately because we only load the tables for the requested font face in `woff2_open_font' and create a single-face sfnt stream. The full discussion is at: https://lists.gnu.org/archive/html/freetype-devel/2019-08/msg00000.html * src/sfnt/sfobjs.c (sfnt_open_font): Add parameter `woff2_num_faces'. (sfnt_init_face): Introduce variable `woff2_num_faces', and change `face->root.num_faces' if `woff2_num_faces' is set. * src/sfnt/sfwoff2.c (woff2_open_font): Validate requested face index and handle negative face indices. * src/sfnt/sfwoff2.h (woff2_open_font): Add parameter `num_faces' to declaration. 2019-08-27 Nikhil Ramakrishnan <ramakrishnan.nikhil@gmail.com> [woff2] Improve memory and error handling. Free up memory after use, and improve error handling. * src/sfnt/sfwoff2.c (reconstruct_font, woff2_open_font): Implement changes. 2019-08-27 Nikhil Ramakrishnan <ramakrishnan.nikhil@gmail.com> [woff2] Avoid too many calls to `FT_REALLOC'. We do this by using `totalSfntSize' as an initial reference, and extending the buffer when required. This reduces rendering time considerably. * include/freetype/internal/wofftypes.h (WOFF2_HeaderRec): Add `totalSfntSize', rename `total_sfnt_size' to `actual_sfnt_size'. * src/sfnt/sfwoff2.c (write_buf): Add parameter `dst_size' to keep track of and update total size of stream. (WRITE_SFNT_BUF, WRITE_SFNT_BUF_AT): Modify macros accordingly. (pad4, store_loca, reconstruct_glyf, reconstruct_hmtx, reconstruct_font): Update parameters to accept `sfnt_size'. (woff2_open_font): Add variable `sfnt_size'. Use WOFF2 header field `totalSfntSize' as initial reference (if value makes sense) and allocate `totalSfntSize' bytes for the sfnt stream. `write_buf' handles reallocation if and when required. Also resize the stream to `actual_sfnt_size' after reconstruction. 2019-08-27 Nikhil Ramakrishnan <ramakrishnan.nikhil@gmail.com> [woff2] Reconstruct `loca', `hmtx', and swap out stream. Add necessary functions to reconstruct loca and hmtx tables (the two remaining tables that can have a transform). `woff2_open_font' is now capable of loading a woff2 font face. This code may still need more refining and better memory management. * include/freetype/internal/wofftypes.h (WOFF2_HeaderRec): Add total (final) size of sfnt stream. (WOFF2_InfoRec): Add header checksum value. * src/sfnt/sfobjs.c (sfnt_open_font): Change `face_instance_index' parameter to its pointer so its value can be modified by `woff2_open_font'. * src/sfnt/sfwoff2.c: (WRITE_SFNT_BUF_AT): New macro to write into sfnt buffer at given position. (write_buf): Add parameter `extend_buf' which allows caller to specify whether buffer should be reallocated before copying data. (WRITE_SFNT_BUF): Updated. (pad4, store_loca, reconstruct_htmx): New functions. (reconstruct_glyf): Calculate loca values and store them. (reconstruct_font): Call `reconstruct_hmtx', write table record entries, and calculate table checksums. Also calculate font checksum and update `checksumAdjustment' entry in head table. (woff2_open_font): Open stream for sfnt buffer, swap out input stream and return. * src/sfnt/sfwoff2.h (woff2_open_font): Modify parameter to accept pointer to `face_index'. 2019-08-27 Nikhil Ramakrishnan <ramakrishnan.nikhil@gmail.com> [woff2] Reconstruct transformed `glyf' table. Reconstruct `glyf' table if it is transformed in the uncompressed table stream. Also add necessary structures, macros and functions. * include/freetype/internal/wofftypes.h (WOFF2_InfoRec, WOFF2_SubstreamRec, WOFF2_PointRec): New structures. (WOFF2_TableRec): s/OrigLength/dst_length/. * src/sfnt/sfwoff2.c (READ_255USHORT, READ_BASE128): Use `FT_SET_ERROR' to set implicit `error' variable. (WRITE_SHORT): New macro. (N_CONTOUR_STREAM, N_POINTS_STREAM, FLAG_STREAM, GLYPH_STREAM, COMPOSITE_STREAM, BBOX_STREAM, INSTRUCTION_STREAM): New macros to refer to substreams of the transformed `glyf' tables. (Read255UShort, ReadBase128): Return errors set by `FT_READ_XXX' macros. (with_sign, safe_int_addition): New functions to add sign to values based on a flag and perform safe addition respectively. (triplet_decode): Decode variable-length (flag, xCoordinate, yCoordinate) triplet for a simple glyph. See https://www.w3.org/TR/WOFF2/#triplet_decoding (store_points, compute_bbox, composteGlyph_size, reconstruct_glyf): New functions. (reconstruct_font): Call `reconstruct_glyf'. * src/sfnt/sfwoff2.h: Add required constants. * src/sfnt/woff2tags.h: Move out constants to `sfwoff2.h'. 2019-08-27 Nikhil Ramakrishnan <ramakrishnan.nikhil@gmail.com> [woff2] Copy un-transformed tables to sfnt stream. Copy un-transformed tables to the sfnt stream. * src/sfnt/sfwoff2.c: (WRITE_SFNT_BUF): New macro. (write_buf): New function. Extend memory of `dst' buffer and copy bytes from `src'. (compute_ULong_sum): New function. Calculate checksum of table. (reconstruct_font): Change `FT_Byte* sfnt' to `FT_Byte** sfnt_bytes'. This has been done because we reallocate memory to `sfnt' multiple times, which may change the pointer value of `sfnt'. This new pointer must be propogated back to the caller. Same reason for using a double pointer in `write_buf'. * src/sfnt/woff2tags.h (WOFF2_DEFAULT_MAX_SIZE): New macro used for overflow checking. 2019-08-27 Nikhil Ramakrishnan <ramakrishnan.nikhil@gmail.com> [woff2] Create stream for uncompressed buffer. Uncompressed buffer is now an `FT_Stream'. Perform basic checks and start iterating over tables. * src/sfnt/sfwoff2.c (stream_close, find_table, read_num_hmetrics): New functions. (reconstruct_font): Modify parameters and iterate over tables. (woff2_open_font): Updated. 2019-08-27 Nikhil Ramakrishnan <ramakrishnan.nikhil@gmail.com> [woff2] Handle TTCs and start reconstructing font. We `handle' TTCs by modifying the `indices' array to point to only those tables that are part of the requested `face_index'. Set and use `num_tables' in `WOFF2_TtcFont'. * src/sfnt/sfwoff2.c (reconstruct_font): New function. (woff2_open_font): Start reconstruction of font. 2019-08-27 Nikhil Ramakrishnan <ramakrishnan.nikhil@gmail.com> [woff2] Get known tags from function. Change `KnownTags' to a function (`woff2_known_tags'). This avoids introducing a global constant array. This function returns the specified index without any checks. The caller must ensure that `index' is within array limits. * src/sfnt/sfwoff2.c (woff2_open_font): Change `KnownTags[...]' notation to `woff2_known_tags( ... )'. * src/sfnt/woff2tags.c: Perform changes. * src/sfnt/woff2tags.h: Update definitions. 2019-08-27 Nikhil Ramakrishnan <ramakrishnan.nikhil@gmail.com> [woff2] Minor. * src/sfnt/sfwoff2.c (woff2_uncompress): Add error message (woff2_open_font): Free `uncompressed_buf'. 2019-08-27 Nikhil Ramakrishnan <ramakrishnan.nikhil@gmail.com> [woff2] Uncompress Brotli streams and `face_index' support. WOFF2 compressed stream is now uncompressed if Brotli is available. This data is stored in a separate buffer (uncompressed_buf) because it does not contain direct table data. Certain tables have transformations applied to them, and they must be reconstructed before we can write those tables to the SFNT stream. `face_index' is now being passed as a parameter to `woff2_open_font'. * src/sfnt/sfobjs.c (sfnt_open_font): Add parameter `face_instance_index'. * src/sfnt/sfwoff2.c (woff2_uncompress): New function. (woff2_open_font): Call `woff2_uncompress'. (compute_first_table_offset): Fix return type. * src/sfnt/sfwoff2.h (woff2_open_font): Modify declaration. 2019-08-27 Nikhil Ramakrishnan <ramakrishnan.nikhil@gmail.com> * builds/unix/configure.raw: Change argument name to `brotli'. 2019-08-27 Nikhil Ramakrishnan <ramakrishnan.nikhil@gmail.com> Add Brotli dependency and required checks. Brotli is required for decompressing WOFF2 font directory streams. The library is thus being added as an optional dependency for FreeType. * builds/unix/configure.raw: Add checks for `libbrotlidec'. (REQUIRES_PRIVATE, LIBS_PRIVATE, LIBSSTATIC_CONFIG): Updated. * devel/ftoption.h, include/freetype/config/ftoption.h (FT_CONFIG_OPTION_USE_BROTLI): New macro. 2019-08-27 Nikhil Ramakrishnan <ramakrishnan.nikhil@gmail.com> [woff2] Write SFNT Offset table. * src/sfnt/sfwoff2.c (WRITE_USHORT, WRITE_ULONG): New macros. (compare_tags): New function.

The same as previous commit but for the old engine. * src/psaux/t1decode.c (t1operator_seac): Implement it. 2019-07-04 Chris Liddell <chris.liddell@artifex.com> [psaux] (1/2) Handle fonts that use SEAC for ligatures (#56580). As originally intended, a Type 1 SEAC charstring would be used for an accented glyph (like `acaron' or `uumlaut'), where the advance width of the SEAC glyph is the same as that of the `base' glyph (like `a' or `u'). In this case it is not uncommon for the SEAC glyph to not use an (H)SBW opcode of its own but to rely on the value from the base glyph. However, out-of-spec fonts also use SEAC glyphs for ligatures (like `oe' or `fi'), and in those cases the overall advance width is greater than that of the `base' glyph. For this reason we have to allow that the SEAC glyph can have an (H)SBW value of its own, and if it has, retain this value, rather than the one from the base glyph. * src/psaux/psintrp.c (cf2_interpT2CharString) <cf2_escSEAC>: Implement it. 2019-07-01 Werner Lemberg <wl@gnu.org> * Version 2.10.1 released. ========================== Tag sources with `VER-2-10-1'. * docs/VERSION.TXT: Add entry for version 2.10.1. * README, Jamfile (RefDoc), src/base/ftver.rc, builds/windows/vc2010/freetype.vcxproj, builds/windows/vc2010/index.html, builds/windows/visualc/freetype.dsp, builds/windows/visualc/freetype.vcproj, builds/windows/visualc/index.html, builds/windows/visualce/freetype.dsp, builds/windows/visualce/freetype.vcproj, builds/windows/visualce/index.html, builds/wince/vc2005-ce/freetype.vcproj, builds/wince/vc2005-ce/index.html, builds/wince/vc2008-ce/freetype.vcproj, builds/wince/vc2008-ce/index.html: s/2.10.0/2.10.1/, s/2100/2101/. * include/freetype/freetype.h (FREETYPE_PATCH): Set to 1. * builds/unix/configure.raw (version_info): Set to 23:1:17. * CMakeLists.txt (VERSION_PATCH): Set to 1. * include/freetype/fterrors.h (FT_Error_String): Fix C++ compilation. 2019-06-26 Alexei Podtelezhnikov <apodtele@gmail.com> * src/bdf/bdfdrivr.c (bdf_cmap_char_{index,next}): Fix inequality.

Update copyright notices. 2019-04-29 Alexei Podtelezhnikov <apodtele@gmail.com> [smooth] Simplify cubic Bézier flattening. The previous implementation is correct but it is too complex. The revised algorithm is based on the fact that each split moves the control points closer to the trisection points on the chord. The corresponding distances are good surrogates for the curve deviation from the straight line. This cubic flattening algorithm is somewhat similar to the conic algorithm based the distance from the control point to the middle of the chord. The cubic distances, however, decrease less predictably but are easy enough to calculate on each step. The new algorithm produces slightly larger number of splits, which is compensated by its simplicity. The overall rendering performance is improved by 1-2%. The larger number of splits does not necessarily result in higher quality, which stays comparable. * src/smooth/ftgrays.c (gray_render_cubic): Replace the split condition. 2019-04-26 Alexei Podtelezhnikov <apodtele@gmail.com> [smooth] Bithacks and cosmetics. * src/smooth/ftgrays.c (gray_record_cell, gray_set_cell, gray_hline, gray_render_conic, gray_convert_glyph_inner): Updated. 2019-04-25 Alexei Podtelezhnikov <apodtele@gmail.com> Optimize Bézier bisections.

This commit fixes the changes from 2018-07-21, which broke charmap iteration.

Before this commit we had code like (FT_Bool)( globals->glyph_styles[gindex] & 0x8000) Since `FT_Bool' is defined to be an `unsigned char', the code evaluated to something like (unsigned char)( 0x8532 & 0x8000) which in turn expanded to (unsigned char)( 0x8000) and finally yielded 0x00 – i.e., false – not as expected.

This one should be clearer. When the rounded monochrome bbox collapses we add a pixel that covers most if not all original cbox. 2018-09-21 Alexei Podtelezhnikov <apodtele@gmail.com> * src/base/ftobjs.c (ft_glyphslot_preset_bimap): Further tweak. 2018-09-21 Ben Wagner <bungeman@google.com> Improve auto-hinter handling of bitmap fonts (#54681). For bitmap fonts, `FT_Load_Glyph' should either return an error or not set the format to `FT_GLYPH_FORMAT_OUTLINE'. However, in this case `FT_Load_Glyph' calls into the auto-hinter which calls back into `FT_Load_Glyph' with `FT_LOAD_NO_SCALE' in the flags, which marks the glyph as `FT_GLYPH_FORMAT_OUTLINE' with an empty path (even though it doesn't have any path). It appears that the auto-hinter should not be called when the face doesn't have outlines. The current test for using the auto-hinter in `FT_Load_Glyph' checks whether the driver supports scalable outlines, but not if the face supports scalable outlines. * src/base/ftobjs.c (FT_Load_Glyph): Directly check whether we have scalable outlines. 2018-09-21 Werner Lemberg <wl@gnu.org> [raster] Fix disappearing vertical lines (#54589). * src/raster/ftraster.c (Vertical_Sweep_Span): Handle special case where both left and right outline exactly pass pixel centers. 2018-09-20 Alexei Podtelezhnikov <apodtele@gmail.com> * src/base/ftobjs.c (ft_glyphslot_preset_bimap): Tiny rounding tweak. This adds pixels in case a contour goes through the center and they need to be turned on in the b/w rasterizer. 2018-09-20 Alexei Podtelezhnikov <apodtele@gmail.com> [pcf] Replace charmap implementation. PCF comes with charmap lookup table, aka PCF encodings.

This generalizes magic outline shifts that make Harmony LCD rendering work in terms of precise two-dimensional RGB subpixel positions. These coordinates are now set in time of the `smooth' module initialization and later used to shift a glyph outline for rendering. FT_RENDER_MODE_LCD and FT_RENDER_MODE_LCD_V use the same coordinates. The letter, however, rotates them before using. The LCD bitmap padding is also calculated using these coordinates. * include/freetype/internal/ftobjs.h (FT_LibraryRec): New array field `lcd_geometry'. * src/base/ftlcdfil.c (ft_lcd_padding): Reworked. * src/base/ftobjs.c (ft_glyphslot_preset_bitmap): Updated accordingly. * src/smooth/ftsmooth.c [!FT_CONFIG_OPTION_SUBPIXEL_RENDERING] (ft_smooth_init): Initialize `lcd_geometry'.

It is rather fundamental to set monochrome bitmap based on rounded CBox because the b/w rasterizer turns on pixels when their centers are inside the glyph outline. The dropout control is unpredictable and can distort narrow glyphs if the bitmap is too wide. Reported by Chris Liddell. * src/base/ftobjs.c (ft_glyphslot_preset_bitmap): If BBox boundaries are too close, adjust them before rounding. 2018-05-15 Werner Lemberg <wl@gnu.org> [psaux] Fix compiler warning (#53915). * src/psaux/psft.c (cf2_freeT1SeacComponent): Do it. 2018-05-15 Werner Lemberg <wl@gnu.org> [sfnt] Fix memory leak in handling `COLR' data. * src/truetype/ttgload.c (TT_Load_Glyph): Free old `layers' array before reassigning allocated memory.

This commit enables OpenType's COLR/CPAL table handling; a typical application are color emojis that can be scaled to any size. If the color palette does not exist or is invalid, the rendering step rasterizes the outline instead. The current implementation assumes that the foreground is black. Enable this by defining option TT_CONFIG_OPTION_COLOR_LAYERS. There are still some issues with metrics; additionally, an API to fetch color layers is missing. * devel/ftoption.h, include/freetype/config/ftoption.h (TT_CONFIG_OPTION_COLOR_LAYERS): New macro. * include/freetype/internal/ftobjs.h (FT_Glyph_LayerRec, FT_Colr_InternalRec): New structures.

AC_COMPILE_IFELSE only tries to compile a `.c' to a `.o'. The Solaris Studio 12.1 through 12.5 compilers see the `-fvisibility=hidden' flag, but ignore it with a warning of: cc: Warning: Option -fvisibility=hidden passed to ld, if ld is invoked, ignored otherwise AC_LINK_IFELSE does the compile and then tries to link the result, at which point the Solaris linker will issue an error: ld: fatal: option '-fvisibility=hidden' is incompatible with building a dynamic executable If we don't use AC_LINK_IFELSE to catch the error, then configure will fail further tests which attempt to link, such as those testing dependencies like `libbz2'. Also, don't try adding `-fvisibility' if we have already added `-xldscope', just use one of them, since Sun Studio 12 and earlier compilers only issue a warning, and don't try passing through to the linker to generate an error, so AC_LINK_IFELSE doesn't catch them.

Reported by Paul Watson <pwatson@redlinepy.com>. * builds/unix/configure.ac: Renamed to... * builds/unix/configure.raw: This which now serves (with appropriate modifications) as a template for configure.ac. * version.sed: New script. * autogen.sh: Generate configure.ac from configure.raw, using FREETYPE_MAJOR, FREETYPE_MINOR, and FREETYPE_PATCH from freetype.h. 2006-05-06 Werner Lemberg <wl@gnu.org> * include/freetype/freetype.h (FREETYPE_PATCH): Set to 1. * builds/unix/configure.ac (version_info): Set to 9:10:3. * builds/win32/visualc/index.html, builds/win32/visualc/freetype.dsp, builds/win32/visualc/freetype.vcproj, builds/freetype.mk (refdoc), Jamfile (RefDoc), README: s/220/221/, s/2.2.0/2.2.1/. Minor updates. * docs/CHANGES, docs/VERSION.DLL, docs/PROBLEMS, README.CVS: Updated. * builds/unix/install-sh: Updated from `texinfo' CVS module at savannah.gnu.org. * devel/ftoption.h: Synchronize with include/freetype/config/ftoption.h. 2006-05-04 Werner Lemberg <wl@gnu.org> * src/lzw/ftlzw2.c: Renamed to... * src/lzw/ftlzw.c: This. * src/lzw/Jamfile, src/lzw/rules.mk: Updated. * builds/mac/FreeType.m68k_cfm.make.txt, builds/mac/FreeType.m68k_far.make.txt, builds/mac/FreeType.ppc_carbon.make.txt, builds/mac/FreeType.ppc_classic.make.txt: Updated. 2006-05-03 David Turner <david@freetype.org> Allow compilation again with C++ compilers. * include/freetype/internal/ftmemory.h (FT_ASSIGNP, FT_ASSIGNP_INNER): New macros which do the actual assignment, and which exist in two variants (for C and C++). Update callers accordingly. 2006-05-03 Werner Lemberg <wl@gnu.org> * include/freetype/config/ftoption.h (FT_STRICT_ALIASING): Removed. 2006-05-02 Werner Lemberg <wl@gnu.org> * include/freetype/internal/ftmemory.h: s/new/newsz/ (for C++). (FT_ALLOC): Remove redundant redefinition. * builds/compiler/gcc-dev.mk (CFLAGS) [g++]: Don't use `-Wstrict-prototypes'. * src/base/ftstream.c (FT_Stream_EnterFrame): Add cast. * include/freetype/config/ftconfig.h (FT_BASE_DEF) [__cplusplus]: Remove `extern'. 2006-05-02 David Turner <david@freetype.org> Update the memory management functions and macros to safely deal with array size buffer overflows. This corresponds to attempts to allocate arrays that are too large. For an example, consider the following code: count = read_uint32_from_file(); array = malloc( sizeof ( Item ) * count ); for ( nn = 0; nn < count; nn++ ) array[nn] = read_item_from_file(); If `count' is larger than `FT_UINT_MAX/sizeof(Item)', the multiplication overflows, and the array allocated os smaller than the data read from the file. In this case, the heap will be trashed, and this can be used as a denial-of-service attack, or make the engine crash later. The FT_ARRAY_NEW and FT_ARRAY_RENEW macros now ensure that the new count is no larger than `FT_INT_MAX/item_size', otherwise a new error code `FT_Err_Array_Too_Large' will be returned. Note that the memory debugger now works again when FT_DEBUG_MEMORY is defined. FT_STRICT_ALIASING has disappeared; the corresponding code is now the default. * include/freetype/config/ftconfig.h (FT_BASE_DEF) [!__cplusplus]: Don't use `extern'. * include/freetype/fterrdef.h (FT_Err_Array_Too_Large): New error code. * include/freetype/internal/ftmemory.h (FT_DEBUG_INNER) [FT_DEBUG_MEMORY]: New macro. (ft_mem_realloc, ft_mem_qrealloc): Pass new object size count also. (ft_mem_alloc_debug, ft_mem_qalloc_debug, ft_mem_realloc_debug, ft_mem_qrealloc_debug, ft_mem_free_debug): Removed. (FT_MEM_ALLOC, FT_MEM_REALLOC, FT_MEM_QALLOC, FT_MEM_QREALLOC, FT_MEM_FREE): Redefine. (FT_MEM_NEW_ARRAY, FT_MEM_RENEW_ARRAY, FT_MEM_QNEW_ARRAY, FT_MEM_QRENEW_ARRAY): Redefine. (FT_ALLOC_MULT, FT_REALLOC_MULT, FT_MEM_QALLOC_MULT, FT_MEM_QREALLOC_MULT): New macros. Update callers where appropriate. (FT_MEM_SET_ERROR): Slightly redefine. * src/base/ftdbgmem.c (_ft_debug_file, _ft_debug_lineno) [FT_DEBUG_MEMORY]: New global variables, replacing... (FT_MemTableRec) [FT_DEBUG_MEMORY]: Remove `filename' and `line_no'. Update all callers. (ft_mem_debug_alloc) [FT_DEBUG_MEMORY]: Avoid possible integer overflow. (ft_mem_alloc_debug, ft_mem_realloc_debug, ft_mem_qalloc_debug, ft_mem_qrealloc_debug, ft_mem_free_debug): Removed. * src/base/ftmac.c (read_lwfn): Catch integer overflow. * src/base/ftrfork.c (raccess_guess_darwin_hfsplus): Ditto. * src/base/ftutil.c: Remove special code for FT_STRICT_ALIASING. (ft_mem_alloc, ft_mem_realloc, ft_mem_qrealloc): Rewrite. * include/freetype/ftstream.h (FT_FRAME_ENTER, FT_FRAME_EXIT, FT_FRAME_EXTRACT, FT_FRAME_RELEASE): Use FT_DEBUG_INNER to report the place where the frames were entered, extracted, exited or released in the memory debugger. * src/base/ftstream.c (FT_Stream_ReleaseFrame) [FT_DEBUG_MEMORY]: Call ft_mem_free. (FT_Stream_EnterFrame) [FT_DEBUG_MEMORY]: Use ft_mem_qalloc. (FT_Stream_ExitFrame) [FT_DEBUG_MEMORY]: Use ft_mem_free. 2006-04-30 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * src/base/ftobjs.c (Mac_Read_POST_Resource): Correct pfb_pos initialization, remove extra cast to copy to pfb_lenpos. This fixes parsing of PFB fonts with MacOS resource fork (bug introduced 2003-09-11). Patch provided by Huib-Jan Imbens <ft@imbens.nl>. 2006-04-29 Werner Lemberg <wl@gnu.org> Further C library abstraction. Based on a patch from msn2@bidyut.com. * include/freetype/config/ftstdlib.h (FT_CHAR_BIT, FT_FILE, ft_fopen, ft_fclose, ft_fseek, ft_ftell, ft_fread, ft_smalloc, ft_scalloc, ft_srealloc, ft_sfree, ft_labs): New wrapper macros for C library functions.

Fix binary compatibility issues for gnustep-back (GNUstep backend module) which still crashes under Sarge. * src/cache/ftccmap.c (FTC_OldCMapType, FTC_OldCMapIdRec, FTC_OldCMapDesc) [FT_CONFIG_OPTION_OLD_INTERNALS]: New data structures and enumerations. (FTC_CMapCache_Lookup) [FT_CONFIG_OPTION_OLD_INTERNALS]: New compatibility code. * src/cache/ftcbasic.c: Fix a silly bug that prevented our `hack' to support rogue clients compiled against 2.1.7 to work correctly. This probably explains the GNUstep crashes with the second release candidate. 2006-02-23 Chia-I Wu <b90201047@ntu.edu.tw> * include/freetype/ftoutln.h (enum FT_Orientation): New value `FT_ORIENTATION_NONE'. * src/base/ftoutln.c (FT_OUTLINE_GET_CONTOUR, ft_contour_has, ft_contour_enclosed, ft_outline_get_orientation): Another version of `FT_Outline_Get_Orientation'. This version differs from the public one in that each part (contour not enclosed in another contour) of the outline is checked for orientation. (FT_Outline_Embolden): Use `ft_outline_get_orientation'. * src/base/ftsynth.c (FT_GlyphSlot_Embolden): Render the outline and use bitmap's embolden routine when the outline one failed. 2006-02-22 Chia-I Wu <b90201047@ntu.edu.tw> * modules.cfg: Compile in ftotval.c and ftxf86.c by default for ABI compatibility. * src/sfnt/sfobjs.c (sfnt_done_face): Fix a memory leak. * src/sfnt/ttsbit0.c (tt_sbit_decoder_load_bit_aligned, tt_sbit_decoder_load_byte_aligned) [FT_OPTIMIZE_MEMORY]: Fix sbit loading. (Only tested with bit aligned sbit with x_pos == 0.) * src/truetype/ttpload.c (tt_face_load_hdmx, tt_face_get_device_metrics) [FT_OPTIMIZE_MEMORY]: `hdmx' is not actually used. 2006-02-21 David Turner <david@freetype.org> Add a new API named FT_Get_TrueType_Engine_Type to determine whether we have a patented, unpatented, or unimplemented TrueType bytecode interpreter. The FT_Get_Module_Flags API was removed consequently. * include/freetype/ftmodapi.h (FT_Module_Get_Flags): Removed. Replaced with... (FT_Get_TrueType_Engine_Type): This. (FT_TrueTypeEngineType): New enumeration. * include/freetype/internal/ftserv.h (FT_SERVICE_TRUETYPE_ENGINE_H): New macro. * src/base/ftobjs.c: Include FT_SERVICE_TRUETYPE_ENGINE_H. (FT_Module_Get_Flags): Removed. Replaced with... (FT_Get_TrueType_Engine_Type): This. * src/truetype/ttdriver.c: Include FT_SERVICE_TRUETYPE_ENGINE_H. (tt_service_truetype_engine): New service structure. (tt_services): Register it. * include/freetype/internal/services/svtteng.h: New file. * src/sfnt/sfobjs.c (sfnt_load_face): Fix silly bug that prevented embedded bitmaps from being correctly listed and used. * src/sfnt/ttmtx.c (tt_face_load_hmtx): Disable memory optimization if FT_CONFIG_OPTION_OLD_INTERNALS is used. The is necessary because libXfont is directly accessing the HMTX data, unfortunately. Fix some compiler warnings. (tt_face_get_metrics): Ditto. * src/pfr/pfrsbit.c (pfr_slot_load_bitmap): Fix handling of character advances. 2006-02-20 David Turner <david@freetype.org> Support binary compatibility with the X.Org server's Xfont library. Note that this change unfortunately prevents memory optimizations for the embedded bitmap loader. * include/freetype/internal/sfnt.h (SFNT_Interface): Move `set_sbit_strike' and `load_sbit_metrics' fields to the location of version 2.1.8. * src/sfnt/sfdriver.c (tt_face_set_sbit_strike_stub): Call FT_Size_Request. (sfnt_interface): Updated. * src/sfnt/ttsbit.c [FT_CONFIG_OPTION_OLD_INTERNALS]: Don't load ttsbit0.c. (tt_load_sbit_metrics): Make `sbit_small_metrics_fields' static. * src/sfnt/ttsbit.h: Updated. 2006-02-17 David Turner <david@freetype.org> * builds/unix/unix-cc.in (LINK_LIBRARY): Don't filter out exported functions anymore. This ensures that all FT_BASE internal functions are available for dynamic linking. * include/freetype/ftcache.h (FTC_IMAGE_TYPE_COMPARE, FTC_IMAGE_TYPE_HASH), src/cache/ftcbasic.c (FTC_OldFontRec, FTC_OldImageDescRec, FTC_ImageCache_Lookup, FTC_Image_Cache_New, FTC_OldImageDesc, FTC_OLD_IMAGE_FORMAT, ftc_old_image_xxx, ftc_image_type_from_old_desc, FTC_Image_Cache_Lookup, FTC_SBitCache_Lookup, FTC_SBit_Cache_New, FTC_SBit_Cache_Lookup) [FT_CONFIG_OPTION_OLD_INTERNALS]: Try to revive old functions of the cache sub-system. We try to recognize old legacy signatures with a gross hack (hope it works). 2006-02-17 Werner Lemberg <wl@gnu.org> * devel/ftoption.h: Synchronize with include/freetype/config/ftoption.h. 2006-02-16 David Turner <david@freetype.org> Massive changes to the internals to respect the internal object layouts and exported functions of FreeType 2.1.7. Note that the cache sub-system cannot be fully retrofitted, unfortunately. * include/freetype/config/ftoption.h (FT_CONFIG_OPTION_OLD_INTERNALS): New macro. * include/freetype/ftcache.h, include/freetype/cache/ftccache.h, include/freetype/cache/ftccmap.h, include/freetype/internal/ftcalc.h, include/freetype/internal/ftdriver.h, include/freetype/internal/ftmemory.h, include/freetype/internal/ftobjs.h, include/freetype/internal/psaux.h, include/freetype/internal/sfnt.h, include/freetype/internal/t1types.h, include/freetype/internal/tttypes.h, src/base/ftcalc.c, src/base/ftdbgmem.c, src/base/ftobjs.c, src/base/ftutil.c, src/bdf/bdfdrivr.c, src/cache/ftccache.c, src/cache/ftccback.h, src/cache/ftcmanag.c, src/cff/cffdrivr.c, src/cid/cidriver.c, src/pcf/pcfdrivr.c, src/pfr/pfrdrivr.c, src/psaux/psauxmod.c, src/sfnt/sfdriver.c, src/truetype/ttdriver.c, src/type1/t1driver.c, src/type1/t1objs.c, src/type42/t42drivr.c, src/winfonts/winfnt.c: Use FT_CONFIG_OPTION_OLD_INTERNALS to revive old functions and data structures. Move newly added structure elements to the end of the affected structure and add stub fields (if FT_CONFIG_OPTION_OLD_INTERNALS is defined) to assure binary compatibility with older FreeType versions. Use FT_CONFIG_OPTION_OLD_INTERNALS to add function stubs for old functions: ft_stub_set_char_sizes ft_stub_set_pixel_sizes Rename the following internal functions to provide the old function names as stubs: FT_Alloc -> ft_mem_alloc FT_QAlloc -> ft_mem_qalloc FT_Realloc -> ft_mem_realloc FT_QRealloc -> ft_mem_qrealloc FT_Free -> ft_mem_free FT_Alloc_Debug -> ft_mem_alloc_debug FT_QAlloc_Debug -> ft_mem_qalloc_debug FT_Realloc_Debug -> ft_mem_realloc_debug FT_QRealloc_Debug -> ft_mem_qrealloc_debug FT_Free_Debug -> ft_mem_free_debug 2006-02-15 Chia-I Wu <b90201047@ntu.edu.tw> * include/freetype/internal/ftobjs.h (FT_Face_InternalRec): Remove unused `max_points' and `max_contours'. * src/cid/cidobjs.c (cid_face_init), src/type1/t1objs.c (T1_Face_Init), src/type42/t42objs.c (T42_Face_Init): Update. * include/freetype/internal/tttypes.h (TT_FaceRec): Remove unused `max_components'. * src/truetype/ttinterp.h (TT_ExecContextRec): Remove unused `loadSize' and `loadStack'. * src/truetype/ttinterp.c (TT_Done_Context, TT_Load_Context), src/sfnt/ttload.c (tt_face_load_maxp): Update. * src/cff/cffobjs.h (cff_size_select), src/sfnt/sfdriver.c (sfnt_interface), src/truetype/ttdriver.c (tt_size_request): Fix compiler errors/warnings when TT_CONFIG_OPTION_EMBEDDED_BITMAPS is not defined. * src/sfnt/ttmtx.c (tt_face_load_hmtx, tt_face_get_metrics): Fix possible segment faults for the non-FT_OPTIMIZE_MEMORY'ed versions. (finally!) For most OpenType tables, `tt_face_load_xxxx' simply loads the table and `face->root' is set later in `sfnt_load_face'. Here, we try to make this work for _all_ tables. Also improve tracing messages. * src/sfnt/ttsbit.c, src/sfnt/ttsbit0.c, src/sfnt/ttload.c, src/sfnt/ttmtx.c: all `tt_face_load_xxxx' should load the table and then exit. Error handling or setting face->root is done later in `sfnt_load_face'. * src/sfnt/sfobjs.c (sfnt_load_face): Work harder. Mac bitmap-only fonts are not scalable. Check that `face->header.Units_Per_EM' is not zero. (LOAD_, LOADM_): Emit pretty trace messages. * src/sfnt/ttsbit0.c (tt_face_load_strike_metrics): Read metrics from `eblc'. * src/sfnt/ttcmap.c (tt_face_build_cmaps), src/sfnt/ttpost.c (load_format_20, load_format_25, tt_face_get_ps_name): Use face->max_profile.numGlyphs, instead of face->root.num_glyphs. 2006-02-14 Werner Lemberg <wl@gnu.org> * include/freetype/ftoutln.h (FT_Outline_Embolden): Mention in documentation that negative strength values are possible. Give an example call. * include/freetype/freetype.h (FT_GlyphSlotRec): Improve documentation of `outline' field. * src/sfnt/sfobjs.c: Include FT_INTERNAL_DEBUG_H. * src/sfnt/sfdriver.c: Include ttmtx.h. * src/autofit/afcjk.c: Include aftypes.h and aflatin.h. 2006-02-14 Chia-I Wu <b90201047@ntu.edu.tw> * src/sfnt/ttmtx.c (tt_face_get_metrics): Typo. 2006-02-14 Chia-I Wu <b90201047@ntu.edu.tw> * src/sfnt/ttmtx.c (tt_face_load_hhea, tt_face_load_hmtx): Simply return error if table is missing. Check table length in non-FT_OPTIMIZE_MEMORY'ed `tt_face_load_hmtx'. * src/sfnt/sfobjs.c (sfnt_load_face): Take care of missing metrics tables. The last change makes Mac bitmap-only font not load and this fixes it. * src/truetype/ttgload.c (load_truetype_glyph): Fix compilation error when FT_CONFIG_OPTION_INCREMENTAL is defined. 2006-02-13 Chia-I Wu <b90201047@ntu.edu.tw> Clean up the SFNT_Interface. In this final pass, `load_hmtx' is split from `load_hhea'. * include/freetype/internal/sfnt.h, src/sfnt/sfdriver.c, src/sfnt/ttmtx.c, src/sfnt/ttmtx.h: Split `hmtx' from `hhea'. * src/sfnt/sfobjs.c (sfnt_load_face): Update. 2006-02-13 Chia-I Wu <b90201047@ntu.edu.tw> * src/sfnt/ttmtx.h, src/sfnt/ttmtx.c: Why are there two copies of code... 2006-02-13 Chia-I Wu <b90201047@ntu.edu.tw> Clean up the SFNT_Interface. In this pass, we want to treat the font directory (offset table and table directory) as a normal table like the others. This also means that TTCs are no longer recognized there but in `init_face'. * include/freetype/internal/sfnt.h (SFNT_Interface), src/sfnt/sfdriver.c: `load_sfnt_header' and `load_directory' are combined and renamed to `load_font_dir'. * src/sfnt/ttload.h, src/sfnt/ttload.c: s/sfnt_dir_check/check_table_dir/. `sfnt_init' is moved to sfobjs.c and renamed to `sfnt_open_font'. `tt_face_load_sfnt_header' and `tt_face_load_directory' are combined and renamed to `tt_face_load_font_dir'. * src/sfnt/sfobjs.c (sfnt_init_face): Recognize TTC here. 2006-02-13 Chia-I Wu <b90201047@ntu.edu.tw> Clean up the SFNT_Interface. Table loading functions are now named after the tables' tags; `hdmx' is TrueType-specific and thus the code is moved to the truetype module; `get_metrics' is moved here from the truetype module so that the code can be shared with the cff module. This pass involves no real changes. That is, the code is moved verbatim mostly. The only exception is the return value of `tt_face_get_metrics'. * include/freetype/internal/sfnt.h, src/sfnt/rules.mk, src/sfnt/sfdriver.c, src/sfnt/sfnt.c, src/sfnt/sfobjs.c, src/sfnt/ttload.c, src/sfnt/ttload.h, src/sfnt/ttsbit.c, src/sfnt/ttsbit.h, src/sfnt/ttsbit0.c: Clean up the SFNT_Interface. * src/sfnt/ttmtx.c, src/sfnt/ttmtx.h: New files. Metrics-related tables' loading and parsing code is moved to here. Move `tt_face_get_metrics' here from the truetype module. The return value is changed from `void' to `FT_Error'. * include/freetype/internal/fttrace.h: New trace: ttmtx. * src/truetype/ttpload.c, src/truetype/ttpload.h: `hdmx' loading and parsing code is moved here. New function `tt_face_load_prep' split from `tt_face_load_fpgm'. `tt_face_load_fpgm' returns `FT_Err_Ok' if `fpgm' doesn't exist. * src/cff/cffgload.c, src/cff/cffobjs.c: Update. * src/truetype/ttgload.c, src/truetype/ttobjs.c: Update. 2006-02-11 Chia-I Wu <b90201047@ntu.edu.tw> * src/autofit/afcjk.c (af_cjk_metrics_init): Fix a stupid bug... * src/autofit/aflatin.c (af_latin_metrics_init_widths): Use AF_LatinMetricsRec as the dummy metrics because we cast the metrics to it later in `af_latin_hints_link_segments'. 2006-02-11 Chia-I Wu <b90201047@ntu.edu.tw> * include/freetype/config/ftoption.h (AF_CONFIG_OPTION_CJK): #define to enable autofit CJK script support. (#define'd by default.) * src/autofit/aflatin.h (AF_LATIN_CONSTANT): New macro. * src/autofit/aflatin.c (af_latin_metrics_init_widths): Make sure that `edge_distance_threshold' is always set. (af_latin_hints_link_segments): Potential divide-by-zero bug. Use latin constant in the scoring formula. * src/autofit/afcjk.c: Minor updates due to the above three changes. * docs/TODO, docs/CHANGES: Updated. 2006-02-09 Chia-I Wu <b90201047@ntu.edu.tw> Introduce experimental autofit CJK module based on akito's autohint patch. You need to #define AF_MOD_CJK in afcjk.c to enable it. * src/autofit/afglobal.c, src/autofit/afcjk.h, src/autofit/afcjk.c, src/autofit/rules.mk, src/autofit/autofit.c, src/autofit/aftypes.h: Add CJK module based on akito's autohint patch. * src/autofit/afhints.h (AF_SegmentRec): New field `len' for the overlap length of the segments. (AF_SEGMENT_LEN, AF_SEGMENT_DIST): New macros. * src/autofit/aflatin.h (af_latin_metrics_init_widths), src/autofit/aflatin.c (af_latin_metrics_init_widths): Made `FT_LOCAL'. Use the character given by the caller. (af_latin_metrics_init_widths, af_latin_hints_link_segments): Scale the thresholds. * src/autofit/afloader.c (af_loader_load_g): Respect AF_SCALER_FLAG_NO_ADVANCE. 2006-02-09 Werner Lemberg <wl@gnu.org> * src/cid/cidparse.c (cid_parse_new): Remove shadowing variable. 2006-02-09 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * src/cid/cidparse.c (cid_parse_new): Fix for abnormally short or broken CIDFont. Reported by Taek Kwan(TK) Lee (see ft-devel 2005-11-02). 2006-02-08 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * builds/unix/configure.ac: Fix bug for `--with-old-mac-fonts' option on UNIX platform. It has been broken since 2006-01-11. 2006-02-01 Werner Lemberg <wl@gnu.org> * src/otvalid/module.mk: s/otvalid_module_class/otv_module_class/. * src/gxvalid/module.mk: s/gxvalid_module_class/gxv_module_class/. * builds/unix/unixddef.mk: Actually do define PLATFORM (fixing change from 2006-01-31). (TOP_DIR, OBJ_DIR): Update. * builds/unix/install.mk (install): Fix path for ftmodule.h. * Makefile, .mk, builds/unix/unix-cc.in, builds/unix-def.in: Use `?=' where appropriate. builds/detect.mk (TOP_DIR), builds/os2/os2-dev.mk (TOP_DIR), builds/win32/w32-dev.mk (TOP_DIR): Removed. Defined elsewhere. 2006-01-31 Werner Lemberg <wl@gnu.org> Implement new, simplified module selection. With GNU make it is now sufficient to modify a single file, `modules.cfg', to control the inclusion of modules and base extension files. This change also fixes the creation of ftmodule.h; it now depends on `modules.cfg' and thus is rebuilt only if necessary. Finally, a version of `ftoption.h' in OBJ_DIR is preferred over the default location. * modules.cfg: New file. * builds/freetype.mk: Don't include `modules.mk'. Include all `rules.mk' files as specified in `modules.cfg'. (FTOPTION_FLAG, FTOPTION_H): New variables. (FT_CFLAGS): Add macro definition for FT_CONFIG_MODULES_H. Add FTOPTION_FLAG. ($(FT_INIT_OBJ)): Don't use FT_MODULE_LIST. (CONFIG_H): Add FTMODULE_H and FTOPTION_H. (INCLUDES): Add DEVEL_DIR. (INCLUDE_FLAGS, FTSYS_SRC, FTSYS_OBJ, FTDEBUG_SRC, FTDEBUG_OBJ, OBJ_M, OBJ_S): Use `:=', not `='. (remove_ftmodule_h): New phony target to delete `ftmodule.h'. (distclean): Add remove_ftmodule_h. * builds/modules.mk: (MODULE_LIST): Removed. (make_module_list, clean_module_list): Replace targets with... (FTMODULE_H_INIT, FTMODULE_H_CREATE, FTMODULE_H_DONE): New variables. Reason for the change is that it is not possible to have a phony prerequisite which is run only if the target file must be rebuilt (phony prerequisites act like subroutines and are always executed). We only want to rebuild `ftmodule.h' if `module.cfg' is changed. Update all callers. ($FTMODULE_H)): Rule to create `ftmodule.h', depending on `modules.cfg'. * builds/toplevel.mk: Rewrite and simplify module handling. (MODULES_CFG, FTMODULE_H): New variables. Include MODULES_CFG. (MODULES): New variable to include all `module.mk' and `rules.mk' files. We no longer use make's `wildcard' function for this. * Makefile (USE_MODULES): Remove. Update all users. (OBJ_DIR): Define it here. * src//module.mk: Change make_module_list: foo foo: ... to FTMODULE_H_COMMANDS += FOO define FOO ... endef in all files. `FTMODULE_H_COMMANDS' is used in `FTMODULE_H_CREATE'. src/base/rules.mk (BASE_EXT_SRC): Use BASE_EXTENSIONS. * builds/unix/detect.mk (setup): Always execute `configure' script. (have_mk): Rename to... (have_Makefile): This. Don't use `strip' function. * builds/unix/unix.mk: Include `install.mk' only if BUILD_PROJECT is defined. (have_mk): Don't use `strip' function. Test for unix-def.mk in OBJ_DIR, not BUILD_DIR (and invert the test accordingly). * builds/unix/install.mk (install, uninstall): Handle `ftmodule.h'. * builds/os2/os2-dev.mk, builds/unix/unix-dev.mk, builds/win32/w32-bccd.mk, builds/win32/w32-dev.mk: Don't define BUILD_DIR but DEVEL_DIR for development header files. * builds/ansi/ansi-def.mk (TOP_DIR, OBJ_DIR), builds/beos/beos-def.mk (TOP_DIR, OBJ_DIR), builds/unix/unix-def.in (TOP_DIR, OBJ_DIR): Removed. Defined elsewhere. * builds/dos/dos-def.mk (OBJ_DIR), builds/os2/os2-def.mk (OBJ_DIR), builds/win32/win32-def.mk (OBJ_DIR): Removed. Defined elsewhere. * builds/unix/unixddef.mk: Don't define BUILD_DIR but DEVEL_DIR for development header files. Don't define PLATFORM. * configure: Copy `modules.cfg' to builddir if builddir != srcdir. Update snippet taken from autoconf's m4sh.m4 to current CVS version. Be more verbose. * include/freetype/config/ftmodule.h: Add comments -- this file is no longer used if FreeType is built with GNU make. * docs/CHANGES, docs/CUSTOMIZE, docs/INSTALL, docs/INSTALL.ANY, docs/INSTALL.GNU, docs/INSTALL.UNX: Document new build mechanism. Other minor updates. * modules.txt: Removed. Contents included in `modules.cfg'. * include/freetype/internal/ftmemory.h (FT_QAlloc_Debug, FT_Free_Debug) [FT_STRICT_ALIASING]: Fix typos. * src/base/ftdbgmem.c (FT_Alloc_Debug, FT_Realloc_Debug, FT_QAlloc_Debug, FT_QRealloc_Debug, FT_Free_Debug) [FT_STRICT_ALIASING]: Implement. 2006-01-31 Chia-I Wu <b90201047@ntu.edu.tw> * src/cff/cffobjs.c (cff_face_init), src/cid/cidobjs.c (cid_face_init), src/pfr/pfrobjs.c (pfr_face_init), src/type1/t1objs.c (T1_Face_Init): Set face->height to MAX(1.2 * units_per_EM, ascender - descender). 2006-01-31 Chia-I Wu <b90201047@ntu.edu.tw> * include/freetype/internal/t1types.h (AFM_FontInfo), src/psaux/afmparse.c, src/tools/test_afm.c: Read `FontBBox', `Ascender', and `Descender' from an AFM. * src/type1/t1afm.c (T1_Read_Metrics): Use the metrics from the AFM. * include/freetype/freetype.h (FT_FaceRec): Mention that fields may be changed after file attachment. 2006-01-28 Werner Lemberg <wl@gnu.org> * src//module.mk (.PHONY): Add. 2006-01-27 Werner Lemberg <wl@gnu.org> README, docs/FTL.TXT: Fix email address for bug reports. Other minor formatting. * devel/ftoption.h: Synchronize with include/freetype/config/ftoption.h. * src/autofit/module.mk (add_autofit_module), src/bdf/module.mk (add_bdf_module), src/type42/module.mk (add_type42_driver): Fix whitespace. * src/smooth/module.mk (add_smooth_renderer): Add lcd and lcdv renderer classes. 2006-01-27 David Turner <david@freetype.org> * builds/unix/configure.ac: Fix build problem on Cygwin. * builds/unix/install.mk (install): Don't install the internal headers, and remove existing ones if found in the target install directory. * src/autofit/afwarp.c: Add simple #ifdef to prevent compilation if the warp hinter isn't active (it shouldn't, still experimental). * Jamfile, include/freetype/config/ftmodule.h: Remove `gxvalid' and `otvalid' from the list of modules that are linked statically to a given FreeType library. Functionality has been moved to the `ftvalid' CVS module. Note also that current Make-based build system still compiles the modules though. * include/freetype/config/ftoption.h (FT_STRICT_ALIASING): New macro which controls the definitions of the memory management functions to avoid warnings with recent versions of GCC. This macro is only here to be disabled, in case we detect problems with the new scheme. NOTE: Disable macro to use the memory debugger -- this will be fixed later! * include/freetype/internal/ftmemory.h, src/base/ftutil.c (FT_Alloc, FT_QAlloc, FT_Realloc, FT_QRealloc, FT_Free) [FT_STRICT_ALIASING]: New versions. * builds/win32/visualc/freetype.dsp: Updating project file to define FT2_BUILD_LIBRARY, and remove gxvalid + otvalid modules from compilation. * builds/freetype.mk (FT_CFLAGS), Jamfile (DEFINES): Define the macro FT2_BUILD_LIBRARY when compiling the library. * include/freetype/config/ftheader.h: Remove inclusions of internal headers except if the macro FT2_BUILD_LIBRARY is defined. * include/freetype/internal/psaux.h (AFM_KernPair, AFM_TrackKern, AFM_FontInfo): Move structure declarations to... * include/freetype/internal/t1types.h: This file. * (many files): Fix compiler warnings. Various minor reorganizations. * src/cff/cffload.c (cff_font_done): Don't free static array `subfonts'. * src/otvalid/otvcommn.c (otv_ClassDef_validate), src/otvalid/otvgpos.c (otv_x_sxy): Fix debugging information. Get rid of writable static variables (i.e., the string table) in afmparse, and fix compilation in FT2_MULTI mode. * src/psaux/afmparse.c: Include ft2build.h and FT_FREETYPE_H. (AFM_MAX_ARGUMENTS): Define... * src/psaux/afmparse.h: Here. * src/psaux/Jamfile (_sources): Add afmparse. * src/psaux/psconv.c: Include psconv.h. * src/type1/t1afm.c: Don't include FT_INTERNAL_TYPE1_TYPES_H but FT_INTERNAL_POSTSCRIPT_AUX_H. * src/type1/t1afm.h: Include FT_INTERNAL_TYPE1_TYPES_H. 2006-01-23 Chia-I Wu <b90201047@ntu.edu.tw> * include/freetype/freetype.h (FT_Select_Size): Rename the second argument from `idx' to `strike_index'. (FT_Size_Request_Type): Add FT_SIZE_REQUEST_TYPE_MAX to the end of this enum. * include/freetype/internal/ftobjs.h (FT_REQUEST_WIDTH, FT_REQUEST_HEIGHT): New macros to get the width and height of a request, in fractional pixels. * include/freetype/internal/ftobjs.h (FT_Select_Metrics, FT_Request_Metrics), src/base/ftobjs.c (FT_Select_Metrics, FT_Request_Metrics): New base functions to set the font metrics. They were part of FT_Select_Size/FT_Request_Size and are made independent functions so that metrics are not set again and again. * src/base/ftobjs.c (FT_Select_Size, FT_Request_Size): Metrics are set only when driver's size_select/size_request is NULL. That is, drivers should set the metrics themselves. (FT_Match_Size): Round before matching. This was what we did and it does cause some problems without rounding. * src/cff/cffobjs.c (cff_size_select), src/truetype/ttdriver.c (tt_size_select): Set the font metrics. s/index/strike_index/.

(OTV_NEST1, OTV_NEST2, OTV_NEST3): Use OTV_NAME and OTV_FUNC to avoid argument expansion by argument prescan. Append `Func' to all affected macros and change them to take just a single argument. Example: `AttachList' is renamed to `AttachListFunc'. * src/otvalid/otvgdef.c, src/otvalid/otvgpos.c, src/otvalid/otvgsub.c, src/otvjstf.c: Append `Func' to macros affected by the changes to OTV_NESTx and modify them to take just a single argument. 2005-06-20 Chia I Wu <b90201047@ntu.edu.tw> * include/freetype/internal/ftobjs.h, src/base/ftobjs.c: New function ft_glyphslot_grid_fit_metrics. * src/truetype/ttgload.c (compute_glyph_metrics): Use ft_glyphslot_grid_fit_metrics. * src/cff/cffgload.c (cff_slot_load), src/cid/cidgload.c (cid_slot_load_glyph), src/type1/t1gload.c (T1_Load_Glyph): Use ft_glyphslot_grid_fit_metrics.

Some beta releases of autotools have extra strings before version number. 2010-02-12 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> Fix overallocating bug in FT_Outline_New_Internal(). * src/base/ftoutln.c (FT_Outline_New_Internal): The length of FT_Outline->points[] should be numPoints, not 2 * numPoints. Found by Paul Messmer, see https://lists.gnu.org/archive/html/freetype-devel/2010-02/msg00003.html 2010-02-10 Ken Sharp <ken.sharp@artifex.com> Really fix Savannah bug #28678 (part 2). Since we consider `sbw' for the horizontal direction only, we still have to synthesize vertical metrics if the user wants to use the vertical writing direction. * src/cff/cffgload.c (cff_slot_load), src/cid/cidgload.c (cid_slot_load_glyph), src/type1/t1gload.c (T1_Load_Glyph): Synthesize vertical metrics (only) if FT_LOAD_VERTICAL_LAYOUT is set. 2010-02-10 Ken Sharp <ken.sharp@artifex.com> Really fix Savannah bug #28678 (part 1). After long discussion, we now consider the character width vector (wx,wy) returned by the `sbw' Type 1 operator as being part of one direction only. For example, if you are using the horizontal writing direction, you get the horizontal and vertical components of the advance width for this direction. Note that OpenType and CFF fonts don't have such a vertical component; instead, the GPOS table can be used to generate two-dimensional advance widths (but this isn't handled by FreeType). * include/freetype/ftincrem.h (FT_Incremental_MetricsRec): Add `advance_v' field to hold the vertical component of the advance value. * src/truetype/ttgload.c (tt_get_metrics), src/cff/cffgload.c (cff_slot_load), src/type1/t1gload.c (T1_Parse_Glyph_And_Get_Char_String), src/cid/cidgload.c (cid_load_glyph): Use it. 2010-02-08 Werner Lemberg <wl@gnu.org> * devel/ftoption.h [FT_CONFIG_OPTION_PIC]: Define. 2010-02-04 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> Prevent NULL pointer dereference passed to FT_Module_Requester. * src/sfnt/sfdriver.c (sfnt_get_interface): Don't use `module'. * src/psnames/psmodule.c (psnames_get_interface): Ditto. * src/cff/cffdrivr.c (cff_get_interface): Check NULL `driver'. * src/truetype/ttdriver.c (tt_get_interface): Ditto. 2010-01-29 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> Fix memory leaks in previous patch. * src/sfnt/sfobjs.c (sfnt_load_face): Don't overwrite the strings allocated for face->root.family_name and style_name. 2010-01-29 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> New parameters for FT_Open_Face() to ignore preferred family names. Preferred family names should be used for legacy systems that can hold only a few faces (<= 4) for a family name. Suggested by Andreas Heinrich. https://lists.gnu.org/archive/html/freetype/2010-01/msg00001.html * include/freetype/ftsnames.h (FT_PARAM_TAG_IGNORE_PREFERRED_FAMILY, FT_PARAM_TAG_IGNORE_PREFERRED_SUBFAMILY): Define. * src/sfnt/sfobjs.c (sfnt_load_face): Check the arguments and ignore preferred family and subfamily names if requested. 2010-01-27 Ken Sharp <ken.sharp@artifex.com> Fix Savannah bug #28678. * src/cff/cffgload.c (cff_slot_load), src/cid/cidgload.c (cid_load_glyph): Handle vertical metrics correctly. * src/type1/t1gload.c (T1_Parse_Glyph_And_Get_Char_String): Handle vertical metrics correctly. (T1_Load_Glyph): Don't synthesize vertical metrics. 2010-01-14 Werner Lemberg <wl@gnu.org> Make FT_Set_Transform work if no renderer is available. * src/base/ftobjs.c (FT_Load_Glyph): Apply `standard' transformation if no renderer is compiled into the library. 2010-01-14 Werner Lemberg <wl@gnu.org> Fix compilation warning. * src/base/ftbase.h: s/LOCAL_DEF/LOCAL/. * src/base/ftobjs.c: Include ftbase.h conditionally. 2010-01-11 Kwang Yul Seo <skyul@company100.net> Provide inline assembly code for RVCT compiler. This is Savannah patch #7059. * include/freetype/config/ftconfig.h (FT_MULFIX_ASSEMBLER, FT_MulFix_arm) [__CC_ARM \|\| __ARM_CC]: Define. 2010-01-08 Ken Sharp <ken.sharp@artifex.com> Fix Savannah bug #28521. Issue #28226 involved a work-around for a font which used the `setcurrentpoint' operator in an invalid way; this operator is only supposed to be used with the result of OtherSubrs, and the font used it directly. The supplied patch removed the block of code which checked this usage entirely. This turns out to be a Bad Thing. If `setcurrentpoint' is being used correctly it should reset the flex flag in the decoder. If we don't do this then the flag never gets reset and we omit any further contours from the glyph (at least until we close the path or similar). * src/psaux/t1decode.c (t1_decoder_parse_charstrings) <op_setcurrentpoint>: Handle `flex_state' correctly. 2010-01-05 Werner Lemberg <wl@gnu.org> Apply reports from clang static analyzer. * src/lzw/ftlzw.c (ft_lzw_file_init), src/base/ftstroke.c (FT_Stroker_ParseOutline), src/base/ftsynth.c (FT_GlyphSlot_Embolden): Remove dead code. * src/base/ftpatent.c (_tt_check_patents_in_table): Initialize `offset_i' and `length_i'. 2010-01-05 Ralph Giles <giles@ghostscript.com> Enable the incremental font interface by default. Ghostscript requires the incremental font interface for handling some Postscript documents. It is moving to using FreeType as its primary renderer; supporting this in the default build makes it Ghostscript to be linked against the system FreeType when one is available. * include/freetype/config/ftoption.h (FT_CONFIG_OPTION_INCREMENTAL): Uncomment. 2010-01-05 Werner Lemberg <wl@gnu.org> Fix Savannah bug #28395. * src/truetype/ttdriver.c (Load_Glyph), src/type1/t1gload.c (T1_Load_Glyph): Don't check `num_glyphs' if incremental interface is used. 2010-01-05 Ken Sharp <ken.sharp@artifex.com> Make Type 1 `seac' operator work with incremental interface. This fixes Savannah bug #28480. * src/psaux/t1decode.c (t1operator_seac): Don't check `glyph_names' if incremental interface is used. 2010-01-04 Ken Sharp <ken.sharp@artifex.com> Make incremental interface work with TrueType fonts. This fixes Savannah bug #28478. * src/truetype/ttgload.c (load_truetype_glyph): Don't check `glyf_offset' if incremental interface is used. 2009-12-31 Lars Abrahamsson <wonko@opera.com> Make compilation with FT_CONFIG_OPTION_PIC work again. * src/base/ftglyph.c (FT_Glyph_To_Bitmap) [FT_CONFIG_OPTION_PIC]: Declare `library' for FT_BITMAP_GLYPH_CLASS_GET. * src/base/ftinit.c (ft_destroy_default_module_classes, ft_create_default_module_classes): Use proper casts (needed for C++ compilation). * src/sfnt/ttcmap.c (tt_cmap13_class_rec): Use FT_DEFINE_TT_CMAP. 2009-12-22 Marc Kleine-Budde <mkl@pengutronix.de> Make freetype-config aware of $SYSROOT. This is Savannah patch #7040. * builds/unix/freetype-config.in: Decorate with ${SYSROOT} where appropriate. 2009-12-20 Werner Lemberg <wl@gnu.org> Fix compiler warning. Reported by Sean. * src/base/ftdbgmem.c [!FT_DEBUG_MEMORY]: ANSI C doesn't like empty source files; however, some compilers warn about an unused variable declaration. This is now replaced with a typedef. 2009-12-18 Werner Lemberg <wl@gnu.org> Fix Savannah bug #28320. There exist corrupt, subsetted fonts (embedded in PDF files) which contain a private dict that ends with an unterminated floating point number (no operator following). We now ignore this error (as acrobat does). * src/cff/cffparse.c (cff_parser_run): Don't emit a syntax error for unterminated floating point numbers. 2009-12-16 Werner Lemberg <wl@gnu.org> Really fix compiler warnings. Reported by Sean. * src/truetype/ttgxvar.c (GX_PT_POINTS_ARE_WORDS, GX_PT_POINT_RUN_COUNT_MASK): Convert enum values to macros. 2009-12-16 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> Improve configure.raw to copy some options from CFLAGS to LDFLAGS. The linker of Mac OS X 10.6 is sensitive to the architecture. If the architectures are specified explicitly for the C compiler, the linker requires the architecture specifications too. * builds/unix/configure.raw: Replace `-isysroot' option parser by more generic argument parser. 2009-12-15 Werner Lemberg <wl@gnu.org> Fix compiler warnings. Reported by Sean. * src/truetype/ttgxvar.c (ft_var_readpackeddeltas): Fix counter data type. 2009-12-14 Ken Sharp <ken.sharp@artifex.com> Ignore invalid `setcurrentpoint' operations in Type 1 fonts. This fixes Savannah bug #28226. At least two wild PostScript files of unknown provenance contain Type 1 fonts, apparently converted from TrueType fonts in earlier PDF versions of the files, which use the `setcurrentpoint' operator inappropriately. FreeType currently throws an error in this case, but Ghostscript and Adobe Distiller both accept the fonts and ignore the problem. This commit #ifdefs out the check so PostScript interpreters using FreeType can render these files. The specification says `setcurrentpoint' should only be used to set the point after a `Subr' call, but these fonts use it to set the initial point to (0,0). Unnecessarily so, as they correctly use an `hsbw' operation which implicitly sets the initial point. * src/psaux/t1decode.c (t1_decoder_parse_charstrings) <op_setcurrentpoint>: Comment out code. 2009-12-14 Bram Tassyns <bramt@enfocus.be> Fix parsing of /CIDFontVersion. This fixes Savannah bug #28287. * src/cid/cidtoken.h: `cid_version' in CID_FaceInfoRec (in t1tables.h) is of type FT_Fixed. 2009-12-14 Werner Lemberg <wl@gnu.org> Trace glyph index in CID module. Suggested in Savannah patch #7023. * src/cid/cidgload.c (cid_load_glyph): Add tracing message. 2009-12-03 Werner Lemberg <wl@gnu.org> Fix compiler warnings. * src/truetype/ttgload.c (tt_get_metrics): Put `Exit' label into the proper preprocessor conditional. * src/pfr/pfrobjs.c (pfr_slot_load): Pacify gcc. 2009-11-25 John Tytgat <John.Tytgat@esko.com> Better handling of start of `eexec' section. This fixes Savannah bug #28090. * src/type1/t1parse.c (T1_Get_Private_Dict): Skip all whitespace characters before start of `eexec' section. 2009-11-20 Werner Lemberg <wl@gnu.org> Fix Savannah bug #27742. * src/base/ftstroke.c (ft_stroker_outside): Avoid silent division by zero, using a threshold for `theta'. 2009-11-20 Werner Lemberg <wl@gnu.org> Fix Savannah bug #28036. * src/type1/t1afm.c (t1_get_index): Fix comparison. 2009-11-16 Werner Lemberg <wl@gnu.org> Fix compiler warnings.

These tricky casts can GCC-4.4 optimizer (-O2) confused and the crashing binaries are generated. * src/cache/ftcmru.h (FTC_MRULIST_LOOKUP_CMP): Drop tricky cast. Now the 4th argument `node' of this function should be typed as FTC_MruNode. * src/cache/ftcglyph.h (FTC_GCACHE_LOOKUP_CMP): For inline implementation, new temporal variable FTC_MruNode `_mrunode' to take the pointer from FTC_MRULIST_LOOKUP_CMP().

The hash API in BDF driver is designed to be generic, it takes void typed data. But BDF driver always gives an unsigned long integer (the index to a property). To reduce non-essential casts from unsigned long to void* and from void* to unsigned long, the hash API is changed to take size_t integer. The issue of incompatible cast between unsigned long and void* on LLP64 platform is reported by NightStrike from MinGW-Win64 project. See https://lists.gnu.org/archive/html/freetype/2009-09/msg00000.html * src/bdf/bdf.h: The type of hashnode->data is changed from void* to size_t. * src/bdf/bdflib.c (hash_insert): Get size_t data, instead of void* data.

(_bdf_parse_start): Calculate the index to the property array by size_t variable. (bdf_get_font_property): Drop a cast to unsigned long. 2009-09-10 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> [Win64] Improve the computation of random seed from stack address. On LLP64 platform, the conversion from pointer to FT_Fixed need to drop higher 32-bit. Explicit casts are required. Reported by NightStrike from MinGW-w64 project.

The calculation of `vertBearingX' is not defined in the OTF font spec so FreeType does a `best effort' attempt. However, this value is defined in the PDF and PostScript specs, and that algorithm is better than the one FreeType currently uses: FreeType: Use the middle of the bounding box as the X coordinate of the vertical origin. Adobe PDF spec: Use the middle of the horizontal advance vector as the X coordinate of the vertical origin. FreeType's algorithm goes wrong if you have a really small glyph (like the full-width, circle-like dot at the end of the sentence, as used in CJK scripts) with large bearings. With the FreeType algorithm this dot gets centered on the baseline; with the PDF algorithm it gets the correct location (in the top right). Note that this is a serious issue, it's like printing the dot at the end of a Roman sentence at the center of the textline instead of on the baseline like it should. So i believe the PDF spec's algorithm should be used in FreeType as well. The `vertBearingY' value for such small glyphs is also very strange if no `vmtx' information is present, since the height of the bbox is not representable for the height of the glyph visually (the whitespace up to the baseline is part of the glyph). The fix also includes some code for a better estimate of `vertBearingY'. * src/base/ftobjs.c (ft_synthesize_vertical_metrics): `vertBearingX' is now calculated as described by the Adobe PDF Spec. Estimate for `vertBearingY' now works better for small glyphs completely above or below the baseline into account. * src/cff/cffgload.c (cff_slot_load): `vertBearingX' is now calculated as described by the Adobe PDF Spec. Vertical metrics information was always ignored when FT_CONFIG_OPTION_OLD_INTERNALS was not defined. * src/truetype/ttgload.c (compute_glyph_metrics): `vertBearingX' is now calculated as described by the Adobe PDF Spec. 2009-09-01 John Tytgat <John.Tytgat@esko.com> Fix custom cmap for empty Type 1 font (Savannah bug #27294). * include/freetype/internal/t1types.h (T1_EncodingRecRec_): Update comment to reflect revised code_last meaning. * src/type1/t1load.c (T1_Open_Face), src/type42/t42objs.c (T42_Open_Face): Assign max_char as highest character code + 1 and use this for T1_EncodingRecRec_::code_last. * src/psaux/t1cmap.c (t1_cmap_custom_init): Follow revised T1_EncodingRecRec_::code_last meaning. 2009-08-25 Werner Lemberg <wl@gnu.org> Fix rendering of horizontally compressed CFFs.

This fixes Savannah bug #26867. Previously, only integers have been used which can lead to serious rounding errors. However, fractional values are only used internally; after the charstrings (of either Type 1 or 2) have been processed, the resulting coordinates get rounded to integers currently -- before applying scaling. This should be fixed; at the same time a new load flag should be introduced, to be used in combination with FT_LOAD_NO_SCALE, which indicates that font units are returned in 16.16 format. Similarly, the incremental interface should be extended to allow fractional values for metrics. * include/freetype/internal/psaux.h (T1_BuilderRec): Remove `shift' field. * include/freetype/internal/pshints.h (T1_Hints_SetStemFunc, T1_Hints_SetStem3Func): Use FT_Fixed for coordinates. * src/psaux/psobjs.c: Include FT_INTERNAL_CALC_H.

Problems reported by suyu@cooee.cn. * src/smooth/ftgrays.c (gray_move_to, gray_raster_render): Use RAS_VAR. 2009-06-18 Werner Lemberg <wl@gnu.org> * docs/CHANGES: Updated. 2009-06-18 Werner Lemberg <wl@gnu.org> Fix B/W rasterization of subglyphs with different drop-out modes. Normally, the SCANMODE instruction (if present) to set the drop-out mode in a TrueType font is located in the `prep' table only and thus valid for all glyphs. However, there are fonts like `pala.ttf' which additionally contain this instruction in the hinting code of some glyphs (but not all). As a result it can happen that a composite glyph needs multiple drop-out modes for its subglyphs since the rendering state gets reset for each subglyph. FreeType collects the hinted outlines from all subglyphs, then it sends the data to the rasterizer. It also sends the drop-out mode -- after hinting has been applied -- and here is the error: It sends the drop-out mode of the last subglyph only; drop-out modes of all other subglyphs are lost. This patch fixes the problem; it adds a second, alternative mechanism to pass the drop-out mode: For each contour, the rasterizer now checks the first `tags' array element. If bit 2 is set, bits 5-7 contain the contour's drop-out mode, overriding the global drop-out mode. * include/freetype/ftimage.h (FT_CURVE_TAG_HAS_SCANMODE): New macro. * src/truetype/ttgload.c (TT_Hint_Glyph): Store drop-out mode in `tags[0]'. * src/raster/ftraster.c (Flow_Up, Overshoot_Top, Overshoot_Bottom): Use bits 3-5 instead of 0-2. (New_Profile): Set the drop-out mode in the profile's `flags' field. (Decompose_Curve): Check `tags[0]' and set `dropOutControl' if necessary. (Vertical_Sweep_Drop, Horizontal_Sweep_Drop, Horizontal_Gray_Sweep_Drop, Draw_Sweep): Use the profile's drop-out mode. 2009-06-16 Werner Lemberg <wl@gnu.org> Improve scan conversion rules 4 and 6. Two new constraints are introduced to better identify a `stub' -- a concept which is only vaguely described in the OpenType specification. The old code was too rigorous and suppressed more pixel than it should. . The intersection of the two profiles with the scanline is less than a half pixel. Code related to this was already present in the sources but has been commented out. . The endpoint of the original contour forming a profile has a distance (`overshoot') less than half a pixel to the scanline. Note that the two additional conditions fix almost all differences to the Windows rasterizer, but some problematic cases remain. * src/raster/ftraster.c (Overshoot_Top, Overshoot_Bottom): New macros for the `flags' field in the `TProfile' structure. (IS_BOTTOM_OVERSHOOT, IS_TOP_OVERSHOOT): New macros. (New_Profile, End_Profile): Pass overshoot flag as an argument and set it accordingly. Update callers.

This patch fixes the following problems in ttsbit0.c: . Bitmaps for compound glyphs were never allocated. . `SBitDecoder' refused to load metrics if some other metrics have already been loaded. This condition certainly makes no sense for recursive calls, so I've just disabled it. Another possibility would be resetting `decoder->metrics_loaded' to false before loading each composite component. However, we must restore the original metrics after finishing the recursion; otherwise we can get a misaligned glyph. . `tt_sbit_decoder_load_bit_aligned' incorrectly handled `x_pos', causing some glyph components to be shifted too far to the right (especially noticeable for small sizes). Note that support for grayscale bitmaps (not necessarily compound) is completely broken in ttsbit0.c. * src/sfnt/tt_sbit_decoder_load_metrics: Always load metrics.

Fix return value for non-PFR fonts. Both problems reported by Chi Nguyen <chint@necsv.com>. 2008-12-21 anonymous FT_USE_MODULE declares things as: extern const FT_Module_Class (or similar for C++). However, the actual types of the variables being declared are often different, e.g., FT_Driver_ClassRec or FT_Renderer_Class. (Some are, indeed, FT_Module_Class.) This works with most C compilers (since those structs begin with an FT_Module_Class struct), but technically it's undefined behavior. To quote the ISO/IEC 9899:TC2 final committee draft, section 6.2.7 paragraph 2: All declarations that refer to the same object or function shall have compatible type; otherwise, the behavior is undefined. (And they are not compatible types.) Most C compilers don't reject (or even detect!) code which has this issue, but the GCC LTO development branch compiler does. (It outputs the types of the objects while generating .o files, along with a bunch of other information, then compares them when doing the final link-time code generation pass.)

At the same time, slightly modify the behaviour of tricky fonts: FT_LOAD_NO_HINTING is now ignored. To really force raw loading of tricky fonts (without hinting), both FT_LOAD_NO_HINTING and FT_LOAD_NO_AUTOHINT must be used. Finally, tricky TrueType fonts always use the bytecode interpreter even if the patented code is used. * include/freetype/freetype.h (FT_FACE_FLAG_TRICKY, FT_IS_TRICKY): New macros. * src/truetype/ttdriver.c (Load_Glyph): Handle new load flags semantics as described above. * src/truetype/ttobjs.c (tt_check_trickyness): New function, using code of ...

This fixes Savannah bug #25010. * src/base/ftobjs.c (FT_Load_Glyph): Reject fonts with neither outlines nor bitmaps. * src/sfnt/sfobjs.c (sfnt_load_face): Don't return an error if there is no table with glyphs. * src/sfnt/ttload.c (tt_face_lookup_table): Improve debugging message. 2008-12-01 Werner Lemberg <wl@gnu.org> GDEF tables need `glyph_count' too for validation.

Other errors are returned by SFNT_Err_Unknown_File_Format. * src/base/ftobjs.c (FT_Open_Face): When TrueType driver returns `FT_Err_Table_Missing', try `open_face_PS_from_sfnt_stream'. It is enabled only when old mac font support is configured. 2008-10-04 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * include/freetype/tttags.h (TTAG_CID, TTAG_FOND, TTAG_LWFN, TTAG_POST, TTAG_sfnt, TTAG_TYP1, TTAG_typ1): New tags to simplify the repeated calculations of these values in ftobjs.c and ftmac.c. * src/base/ftobjs.c: Replace all FT_MAKE_TAG by new tags. * src/base/ftmac.c: Ditto. * builds/mac/ftmac.c: Ditto. 2008-10-04 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * src/base/ftobjs.c (ft_lookup_PS_in_sfnt_stream): Remove wrong initialization of is_sfnt_cid. 2008-10-04 Werner Lemberg <wl@gnu.org> src/base/ftobjs.c (open_face_PS_from_sfnt_stream): Remove compiler warnings. 2008-10-04 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * src/base/ftobjs.c (ft_lookup_PS_in_sfnt): Replaced by... (ft_lookup_PS_in_sfnt_stream): This. (open_face_PS_from_sfnt_stream): New function. It checks whether the stream is sfnt-wrapped Type1 PS font or sfnt-wrapped CID-keyed font, then try to open a face for given face_index. (Mac_Read_sfnt_Resource): Replace the combination of `ft_lookup_PS_in_sfnt' and `open_face_from_buffer' by `open_face_PS_from_sfnt_stream'. * src/base/ftmac.c (FT_New_Face_From_SFNT): Ditto. * builds/mac/ftmac.c (FT_New_Face_From_SFNT): Ditto. * src/base/ftbase.h: Remove `ft_lookup_PS_in_sfnt' and add `open_face_PS_from_sfnt_stream'. 2008-10-03 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * src/base/ftobjs.c (ft_lookup_PS_in_sfnt): Set is_sfnt_cid to FALSE if neither `CID ' nor `TYP1' is found in the sfnt container. 2008-10-03 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> include/freetype/config/ftconfig.h: Define FT_MACINTOSH when SC or MrC compiler of MPW is used. These compilers do not define the macro __APPLE__ by themselves. * builds/unix/ftconfig.in: Ditto. * builds/vms/ftconfig.h: Ditto. * src/base/ftbase.c: Use FT_MACINTOSH instead of __APPLE__, to include ftmac.c if FreeType 2 is built by MPW. * src/base/ftobjs.c: Use FT_MACINTOSH instead of __APPLE__, to enable shared functions for ftmac.c if FreeType 2 is built by MPW. * builds/mac/ftmac.c: Include ftbase.h.

(ft_lookup_PS_in_sfnt): Ditto. * builds/mac/FreeType.m68k_far.make.txt: Build ftmac.c as an included part of ftbase.c, to share the functions in ftobjs.c. The rule compiling ftmac.c separately is removed and the rule copying ftbase.c from src/base/ftbase.c to builds/mac/ftbase.c is added. * builds/mac/FreeType.m68k_cfm.make.txt: Ditto. * builds/mac/FreeType.ppc_classic.make.txt: Ditto. * builds/mac/FreeType.ppc_carbon.make.txt: Ditto. 2008-10-02 Bram Tassyns <bramt@enfocus.be> * src/cff/cffgload.c (cff_slot_load): Map CID 0 to GID 0. This fixes Savannah bug #24430. 2008-10-02 Werner Lemberg <wl@gnu.org> * builds/freetype.mk (BASE_H): Rename to... (INTERNAL_H): This.

Currently, `ft_lookup_PS_in_sfnt' and `open_face_from_buffer' are declared to share between ftobjs.c and ftmac.c. * src/base/rule.mk: Add ftbase.h. * src/base/ftobjs.c: Include ftbase.h. (memory_stream_close): Build on any platform when old MacOS font support is enabled. (new_memory_stream): Ditto. (open_face_from_buffer): Build on any platform when old MacOS font support is enabled. The counting of the face in a font file is slightly different between Carbon-dependent parser and Carbon-free parser. They are merged with the platform-specific conditional. (ft_lookup_PS_in_sfnt): Ditto. * src/base/ftmac.c: Include ftbase.h. (memory_stream_close): Removed. (new_memory_stream): Ditto. (open_face_from_buffer): Removed. Use the implementation in ftobjs.c.

Reported by Graham Asher. 2008-09-30 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * src/base/rules.mk: Add conditional source to BASE_SRC, for `make multi' on Mac OS X. If the macro $(ftmac_c) is defined, $(BASE_DIR)/$(ftmac_c) is added to BASE_SRC. In a normal build, the lack of ftmac.c in BASE_SRC is not serious because ftbase.c includes ftmac.c. * builds/unix/unix-def.in: Add a macro definition of $(ftmac_c). * builds/unix/configure.raw: Add procedure to set up appropriate value of $(ftmac_c) with the consideration of the availability of Carbon framework. 2008-09-30 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * src/base/Jamfile: Add target for multi build by jam on Mac OS X. * src/base/ftobjs.c (FT_New_Face): Fix the condition to include this function for MPW building.

(ft_lookup_PS_in_sfnt): New function to look up `TYP1' or `CID ' table in sfnt table directory. It is used before loading TrueType font driver. * docs/CHANGES: Add note about the current status of sfnt-wrapped Type1 and sfnt-wrapped CID-keyed font support. 2008-09-18 Werner Lemberg <wl@gnu.org> * src/base/ftsystem.c (FT_Done_Memory): Use ft_sfree directly for orthogonality (ft_free and ft_sfree could belong to different memory pools). This fixes Savannah bug #24297. 2008-09-18 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * src/cff/cffobjs.c (cff_face_init): Use TTAG_OTTO defined in tttags.h instead of numerical value 0x4F54544FL. 2008-09-16 Werner Lemberg <wl@gnu.org> * src/cff/cffgload.h, src/cff/cffgload.c (cff_decoder_set_width_only): Eliminate function call. 2008-09-15 George Williams <gww@silcom.com> Fix Savannah bug #24179, reported by Bram Tassyns. * src/type1/t1load.c (mm_axis_unmap, T1_Get_MM_Var): Fix computation of default values. 2008-09-15 Werner Lemberg <wl@gnu.org> * src/tools/glnames.py (main): Surround `ft_get_adobe_glyph_index' and `ft_adobe_glyph_list' with FT_CONFIG_OPTION_ADOBE_GLYPH_LIST to prevent unconditional definition. This fixes Savannah bug #24241. * src/psnames/pstables.h: Regenerated. 2008-09-13 Werner Lemberg <wl@gnu.org> * autogen.sh, builds/unix/configure.raw, include/freetype/config/ftconfig.h, builds/unix/ftconfig.in: Minor beautifying. * include/freetype/ftadvanc.h, include/freetype/ftgasp.h, include/freetype/ftlcdfil.h: Protect against FreeType 1.

(FT_USE_AUTOCONF_SIZEOF_TYPES): New macro. If defined, the cpp computation is disabled and the statically configured sizes are used. This fixes Savannah bug #21250. * builds/unix/configure.raw: Add the checks to compare the cpp computation results of the bit length of int and long versus the sizes detected by running `configure'. If the results are different, FT_USE_AUTOCONF_SIZEOF_TYPES is defined to prioritize the results. New option --{enable\|disable}-biarch-config is added to define or undefine FT_USE_AUTOCONF_SIZEOF_TYPES manually. 2008-09-05 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * builds/unix/configure.raw: Clear FT2_EXTRA_LIBS when Carbon or ApplicationServices framework is missing. Although this value is not used in building of FreeType2, it is written in `freetype2.pc' and `freetype-config'. 2008-09-01 David Turner <david@freetype.org> * src/cache/ftccmap.c (FTC_CMapCache_Lookup): Accept a negative cmap index to mean `use default cached FT_Face's charmap'. This fixes Savannah bug #22625. * include/freetype/ftcache.h: Document it. Make FT_MulFix an inlined function. This is done to speed up FreeType a little (on x86 3% when loading+hinting, 10% when rendering, ARM savings are more important though). Disable this by undefining FT_CONFIG_OPTION_INLINE_MULFIX. Use of assembler code can now be controlled with FT_CONFIG_OPTION_NO_ASSEMBLER. * include/freetype/config/ftconfig.h, builds/unix/ftconfig.in [!FT_CONFIG_OPTION_NO_ASSEMBLER] (FT_MulFix_arm): New assembler implementation. [!FT_CONFIG_OPTION_NO_ASSEMBLER] (FT_MulFix_i386): Assembler implementation taken from `ftcalc.c'. [!FT_CONFIG_OPTION_NO_ASSEMBLER] (FT_MULFIX_ASSEMBLER): New macro which is defined to the platform-specific assembler implementation of FT_MulFix.

Add a new header named FT_ADVANCES_H declaring some new APIs to extract the advances of one or more glyphs without necessarily loading their outlines. Also provide `fast loaders' for the TrueType, Type1, and CFF font drivers (more to come later). * src/base/ftadvanc.c, include/freetype/ftadvanc.h: New files. * include/freetype/config/ftheader.h (FT_ADVANCES_H): New macro. * include/freetype/freetype.h (FT_LOAD_ADVANCE_ONLY): New macro. * include/freetype/internal/ftdriver.h (FT_Face_GetAdvancesFunc): `flags' and `advances' are now of type `FT_UInt' and `FT_Fixed', respectively. * src/base/Jamfile (_sources), src/base/rules.mk (BASE_SRC): Add ftadvanc.c. * src/cff/cffdrivr.c (cff_get_advances): New function. (cff_driver_class): Register it. * src/cff/cffgload.c (cff_decoder_set_width_only): New function. (cff_decoder_parse_charstrings): Handle `width_only'. (cff_slot_load): Handle FT_LOAD_ADVANCE_ONLY. * src/cff/cffgload.h (cff_decoder): New element `width_only'. (cff_decoder_set_width_only): New declaration. * src/truetype/ttdriver.c (tt_get_advances): New function. (tt_driver_class): Register it. * src/truetype/ttgload.c (Get_HMetrics, Get_VMetrics): Renamed to... (TT_Get_HMetrics, TT_Get_VMetrics): This. Update callers. * src/truetype/ttgload.h: Declare them. * src/type1/t1gload.h, src/type1/t1gload.c (T1_Get_Advances): New function. * src/type1/t1driver.c (t1_driver_class): Register T1_Get_Advances. Add checks for minimum version of the `autotools' stuff. * autogen.sh: Implement it. (get_major_version, get_minor_version, get_patch_version, compare_to_minimum_version, check_tool_version): New auxiliary functions. * README.CVS: Document it. 2008-08-29 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * src/sfnt/sfobjs.c (sfnt_open_font): Use TTAG_OTTO defined in tttags.h instead of FT_MAKE_TAG( 'O', 'T', 'T', 'O' ). 2008-08-28 Werner Lemberg <wl@gnu.org> * src/type1/t1load.c (parse_encoding): Protect against infinite loop. This fixes Savannah bug #24150 (where a patch has been posted too). 2008-08-23 Werner Lemberg <wl@gnu.org> * src/type/t1afm.c (compare_kern_pairs), src/psaux/afmparse.c (afm_compare_kern_pairs): Fix comparison. This fixes Savannah bug #24119. 2008-08-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * src/base/ftobjs.c (FT_Stream_New): Initialize astream always, even if passed library or arguments are invalid. This fixes a bug that an uninitialized stream is freed when an invalid library handle is passed. Originally proposed by Mike Fabian, 2008/08/18 on freetype-devel. (FT_Open_Face): Ditto (stream). (load_face_in_embedded_rfork): Ditto (stream2). 2008-08-18 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> src/base/ftmac.c: Add a fallback to guess the availability of the `ResourceIndex' type. It is used when built without configure (e.g., a build with Jam). * builds/mac/ftmac.c: Ditto. * builds/unix/configure.raw: Set HAVE_TYPE_RESOURCE_INDEX to 1 or 0 explicitly, even if `ResourceIndex' is unavailable. 2008-08-18 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * builds/unix/configure.raw: In checking of Mac OS X features, all-in-one header file `Carbon.h' is replaced by the minimum header file `CoreServices.h', similar to current src/base/ftmac.c. 2008-08-18 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * src/sfnt/ttcmap.c (tt_cmap2_validate): Skip the validation of sub-header when its code_count is 0. Many Japanese Dynalab fonts include such an empty sub-header (code_count == 0, first_code == 0 delta == 0, but offset != 0) as the second sub-header in SJIS cmap. 2008-08-04 Werner Lemberg <wl@gnu.org> * src/type1/t1tokens.h: Handle `ForceBold' keyword. This fixes Savannah bug #23995. * src/cid/cidload.c (parse_expansion_factor): New callback function. (cid_field_records): Use it for `ExpansionFactor'. * src/cod/cidtoken.h: Handle `ForceBold' keyword. Don't handle `ExpansionFactor'. 2008-08-04 Bram Tassyns <bramt@enfocus.be> * src/cff/cffparse.c (cff_parse_fixed_scaled): Fix thinko which resulted in incorrect scaling. This fixes Savannah bug #23973. 2008-08-04 Werner Lemberg <wl@gnu.org> Be more tolerant w.r.t. invalid entries in SFNT table directory. * src/sfnt/ttload.c (check_table_dir): Ignore invalid entries and adjust table count. Add more trace messages. (tt_face_load_font_dir): Updated. 2008-07-30 Werner Lemberg <wl@gnu.org> * src/cff/cffgload.c (cff_decoder_parse_charstrings): No longer assume that the first argument on the stack is the bottom-most element. Two reasons: o According to people from Adobe it is missing in the Type 2 specification that pushing of additional, superfluous arguments on the stack is prohibited. o Acroread in general handles fonts differently, namely by popping the number of arguments needed for a particular operand (as a PS interpreter would do). In case of buggy fonts this causes a different interpretation which of the elements on the stack are superfluous and which not. Since there are CFF subfonts (embedded in PDFs) which rely on Acroread's behaviour, FreeType now does the same. 2008-07-27 Werner Lemberg <wl@gnu.org> Add extra mappings for `Tcommaaccent' and `tcommaaccent'. This fixes Savannah bug #23940. * src/psnames/psmodule.c (WGL_EXTRA_LIST_SIZE): Rename to... (EXTRA_GLYPH_LIST_SIZE): This. Increase by 2. (ft_wgl_extra_unicodes): Rename to...

(ft_extra_glyph_name_offsets): This. Add two offsets. (ps_check_wgl_name, ps_check_wgl_unicode): Rename to... (ps_check_extra_glyph_name, ps_check_extra_glyph_unicode): This. Updated. (ps_unicodes_init): Updated. 2008-07-26 Werner Lemberg <wl@gnu.org> * src/cff/cffgload.c (cff_decoder_prepare, cff_decoder_parse_charstrings): Improve debug output. 2008-07-22 Martin McBride <mmcbride@emtex.com> * src/sfnt/ttcmap.c (tt_cmap4_validate, tt_cmap4_char_map_linear, tt_cmap4_char_map_binary): Handle fonts which treat the last segment specially. According to the specification, such fonts would be invalid but acroread accepts them. 2008-07-16 Jon Foster <Jon.Foster@cabot.co.uk> * src/pfr/pfrdrivr.c (pfr_get_advance): Fix off-by-one error. * src/base/ftcalc.c (FT_MulFix): Fix portability issue. * src/sfnt/ttpost.c (MAC_NAME) [!FT_CONFIG_OPTION_POSTSCRIPT_NAMES]: Fix compiler warning. 2008-07-16 Werner Lemberg <wl@gnu.org> Handle CID-keyed fonts wrapped in an SFNT (with cmaps) correctly. * src/cff/cffload.c (cff_font_load): Pass `pure_cff'. Invert sids table only if `pure_cff' is set. * src/cff/cffload.h: Updated. * src/cff/cffobjs.c (cff_face_init): Updated. Set FT_FACE_FLAG_CID_KEYED only if pure_cff is set. * docs/CHANGES: Updated. 2008-07-09 Werner Lemberg <wl@gnu.org> * src/truetype/ttpload.c (tt_face_load_loca): Handle buggy fonts where num_locations < num_glyphs. Problem reported by Ding Li. 2008-07-05 Werner Lemberg <wl@gnu.org> Since FreeType uses `$(value ...)', we now need GNU make 3.80 or newer. This fixes Savannah bug #23648. * configure: zsh doesn't like ${1+"$@"}. Update needed GNU make version. * builds/toplevel.mk: Check for `$(eval ...)'. * docs/INSTALL.GNU, docs/INSTALL.CROSS, docs/INSTALL.UNIX: Document it. 2008-07-04 Werner Lemberg <wl@gnu.org> * src/raster/ftraster.c (Draw_Sweep): If span is smaller than one pixel, only check for dropouts if neither start nor end point lies on a pixel center. This fixes Savannah bug #23762. 2008-06-29 Werner Lemberg <wl@gnu.org> * Version 2.3.7 released. ========================= Tag sources with `VER-2-3-7'. * docs/CHANGES, docs/VERSION.DLL: Update documentation and bump version number to 2.3.7. * README, Jamfile (RefDoc), builds/win32/visualc/index.html, builds/win32/visualc/freetype.dsp, builds/win32/visualc/freetype.vcproj, builds/win32/visualce/index.html, builds/win32/visualce/freetype.dsp, builds/win32/visualce/freetype.vcproj: s/2.3.6/2.3.7/, s/236/237/. * include/freetype/freetype.h (FREETYPE_PATCH): Set to 7. * builds/unix/configure.raw (version_info): Set to 9:18:3. * docs/release: Updated. 2008-06-28 Werner Lemberg <wl@gnu.org> * src/ftglyph.c (FT_Matrix_Multiply, FT_Matrix_Invert): Move to... * src/ftcalc.c: Here.

Update header files accordingly. 2008-06-24 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * builds/unix/configure.raw: Check type `ResourceIndex' explicitly and define HAVE_TYPE_RESOURCE_INDEX if it is defined. Mac OS X 10.5 bundles 10.4u SDK with MAC_OS_X_VERSION_10_5 macro but without ResourceIndex type definition. The macro does not inform the type availability. * src/base/ftmac.c: More parentheses are inserted to clarify the conditionals to disable legacy APIs in `10.5 and later' cases. If HAVE_TYPE_RESOURCE_INDEX is not defined, ResourceIndex is defined. 2008-06-24 Werner Lemberg <wl@gnu.org> * src/truetype/ttinterp.c (Ins_SCANTYPE): Don't check rendering mode. * src/raster/ftraster.c (Render_Glyph, Render_Gray_Glyph, Draw_Sweep): No-dropout mode is value 2, not value 0. (Draw_Sweep): Really skip dropout handling for no-dropout mode. 2008-06-24 Werner Lemberg <wl@gnu.org> * src/psaux/psobjs.c (t1_builder_close_contour): Don't add contour if it consists of one point only. Based on a patch from Savannah bug #23683 (from John Tytgat). 2008-06-22 Werner Lemberg <wl@gnu.org> * src/truetype/ttgload.c (TT_Load_Glyph): Protect bytecode stuff with IS_HINTED. * docs/CHANGES: Updated. 2008-06-22 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * builds/unix/configure.raw: If CFLAGS has `-isysroot XXX' option but LDFLAGS does not, import it to LDFLAGS. The option is used to specify non-default SDK on Mac OS X (e.g., universal binary SDK for Mac OS X 10.4 on PowerPC platform). Although Apple TechNote 2137 recommends to add the option only to CFLAGS, LDFLAGS should include it because libfreetype.la is built with -no-undefined. This fixes a bug reported by Ryan Schmidt in MacPorts, https://trac.macports.org/ticket/15331. 2008-06-21 Werner Lemberg <wl@gnu.org> Enable access to the various dropout rules of the B&W rasterizer. Pass dropout rules from the TT bytecode interpreter to the rasterizer. * include/freetype/ftimage.h (FT_OUTLINE_SMART_DROPOUTS, FT_OUTLINE_EXCLUDE_STUBS): New flags for FT_Outline. * src/raster/ftraster.c (Vertical_Sweep_Drop, Horizontal_Sweep_Drop, Horizontal_Gray_Sweep_Drop): Use same mode numbers as given in the OpenType specification. Fix mode 4 computation. (Render_Glyph, Render_Gray_Glyph): Handle new outline flags. * src/truetype/ttgload.c (TT_Load_Glyph) Convert scan conversion mode to FT_OUTLINE_XXX flags. * src/truetype/ttinterp.c (Ins_SCANCTRL): Enable ppem check. 2008-06-19 Werner Lemberg <wl@gnu.org> * src/cff/cffobjs.c (cff_face_init): Compute final `dict->units_per_em' value before assigning it to `cffface->units_per_EM'. Otherwise, CFFs without subfonts are scaled incorrectly if the font matrix is non-standard. This fixes Savannah bug #23630. * docs/CHANGES: Updated. 2008-06-19 Werner Lemberg <wl@gnu.org> * src/type/t1objs.c (T1_Face_Init): Slightly improve algorithm fix from 2008-06-19. 2008-06-18 Werner Lemberg <wl@gnu.org> * src/type/t1objs.c (T1_Face_Init): Fix change from 2008-03-21. Reported by Peter Weilbacher <mozilla@weilbacher.org>. * docs/CHANGES: Updated. 2008-06-15 George Williams <gww@silcom.com> * src/otvalid/otvgpos.c (otv_MarkBasePos_validate): Set `valid->extra2' to 1. This is undocumented in the OpenType 1.5 specification. 2008-06-15 Werner Lemberg <wl@gnu.org> * src/base/ftcalc.c (FT_MulFix) <asm>: Protect registers correctly from clobbering. Patch from Savannah bug report #23556. * docs/CHANGES: Document it. 2008-06-10 Werner Lemberg <wl@gnu.org> * autogen.sh: Add option `--install' to libtoolize. 2008-06-10 Werner Lemberg <wl@gnu.org> * Version 2.3.6 released. ========================= Tag sources with `VER-2-3-6'. * docs/CHANGES, docs/VERSION.DLL: Update documentation and bump version number to 2.3.6. * README, Jamfile (RefDoc), builds/win32/visualc/index.html, builds/win32/visualc/freetype.dsp, builds/win32/visualc/freetype.vcproj, builds/win32/visualce/index.html, builds/win32/visualce/freetype.dsp, builds/win32/visualce/freetype.vcproj: s/2.3.5/2.3.6/, s/235/236/. * include/freetype/freetype.h (FREETYPE_PATCH): Set to 6. * builds/unix/configure.raw (version_info): Set to 9:17:3. * include/freetype/internal/psaux.h (T1_BuilderRec): Remove `scale_x' and `scale_y'. * src/cff/cffgload.h (CFF_Builder): Remove `scale_x' and `scale_y'. * src/cff/cffparse.c: Include FT_INTERNAL_DEBUG_H. * src/cff/cffobjs.h: Include FT_INTERNAL_POSTSCRIPT_HINTS_H. 2008-06-10 Werner Lemberg <wl@gnu.org> * src/base/ftobjs.c (open_face): Check `clazz->init_face' and `clazz->done_face'. 2008-06-09 VaDiM <s_sliva@rambler.ru> Support debugging on WinCE. From Savannah patch #6536; this fixes bug #23497. * builds/win32/ftdebug.c (OutputDebugStringEx): New function/macro as a replacement for OutputDebugStringA (which WinCE doesn't have). Update all callers. (ft_debug_init) [_WIN32_CE]: WinCE apparently doesn't have environment variables. 2008-06-09 Werner Lemberg <wl@gnu.org> * README.CVS: Updated. * builds/unix/configure.raw, builds/unix/freetype-config.in: Updated for newer versions of autoconf and friends. 2008-06-08 Werner Lemberg <wl@gnu.org> * src/type1/t1parse.h (T1_ParserRec): Make `base_len' and `private_len' unsigned. * src/type1/t1parse.c (read_pfb_tag): Make `asize' unsigned and read it as such. (T1_New_Parser, T1_Get_Private_Dict): Make `size' unsigned. * src/base/ftstream.c (FT_Stream_Skip): Reject negative values. * src/type1/t1load.c (parse_blend_design_positions): Check `n_axis' for sane value. Fix typo. * src/psaux/psobjs.c (ps_table_add): Check `idx' correctly. * src/truetype/ttinterp (Ins_SHC): Use BOUNDS() to check `last_point'. * src/sfnt/ttload.c (tt_face_load_max_profile): Limit `maxTwilightPoints'. 2008-06-06 Werner Lemberg <wl@gnu.org> * src/truetype/ttinterp.c (Ins_IP): Handle case `org_dist == 0' correctly. This fixes glyphs `t' and `h' of Arial Narrow at 12ppem. 2008-06-03 Werner Lemberg <wl@gnu.org> * include/freetype/ftcache.h (FTC_FaceID): Change type back to FT_Pointer. Reported by Ian Britten <britten@caris.com>. 2008-06-02 Werner Lemberg <wl@gnu.org> Emit header info for defined FreeType objects in reference. * src/tools/docmaker/content.py (re_header_macro): New regexp. (ContentProcessor::__init__): Initialize new dictionary `headers'. (DocBlock::__init__): Collect macro header definitions. * src/tools/docmaker/tohtml.py (header_location_header, header_location_footer): New strings. (HtmlFormatter::__init__): Pass `headers' dictionary. (HtmlFormatter::print_html_field): Don't emit paragraph tags. (HtmlFormatter::print_html_field_list): Emit empty paragraph. (HtmlFormatter::block_enter): Emit header info. 2008-06-01 Werner Lemberg <wl@gnu.org> * include/freetype/config/ftheader.h (FT_UNPATENTED_HINTING_H, FT_INCREMENTAL_H): Added. 2008-05-28 Werner Lemberg <wl@gnu.org> * src/tools/docmaker/sources.py (SourceBlock::__init__): While looking for markup tags, return immediately as soon a single one is found. 2008-05-28 Werner Lemberg <wl@gnu.org> * src/truetype/ttinterp.c (Ins_MD): The MD instruction also uses original, unscaled input values. Confirmed by Greg Hitchcock from Microsoft. 2008-05-27 Werner Lemberg <wl@gnu.org> * src/tools/docmaker/tohtml.py (block_footer_start, block_footer_middle): Beautify output. 2008-05-25 Werner Lemberg <wl@gnu.org> * src/raster/ftraster.c (fc_black_render): Return 0 when we are trying to render into a zero-width/height bitmap, not an error code. * src/truetype/ttgload.c (load_truetype_glyph): Move initialization of the graphics state for subglyphs to... (TT_Hint_Glyph): This function. Hinting instructions for a composite glyph apparently refer to the just hinted subglyphs, not the unhinted, unscaled outline. This seems to fix Savannah bugs #20973 and (at least partially) #23310. 2008-05-20 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * src/base/ftmac.c (FT_New_Face_From_Suitcase): Check if valid `aface' is returned by FT_New_Face_From_FOND(). The patch was proposed by an anonymous reporter of Savannah bug #23204. 2008-05-18 Werner Lemberg <wl@gnu.org> * src/pshinter/pshalgo.c (ps_hints_apply): Reset scale values after correction for pixel boundary. Without this patch, the effect can be cumulative under certain circumstances, making glyphs taller and taller after each call. This fixes Savannah bug #19976. 2008-05-18 Werner Lemberg <wl@gnu.org> * src/base/ftdebug.c (FT_Message, FT_Panic): Send output to stderr. This fixes Savannah bug #23280. * docs/CHANGES: Updated. 2008-05-18 David Turner <david@freetype.org> * src/psnames/psmodule.c (ft_wgl_extra_unicodes, ft_wgl_extra_glyph_names, ft_wgl_extra_glyph_name_offsets, ps_check_wgl_name, ps_check_wgl_unicode): Use `static' to make declarations non-global. * src/type1/t1load.c: Add missing comment. 2008-05-17 Sam Hocevar <samh> * src/truetype/ttgload.c (TT_Load_Simple_Glyph): Handle zero-contour glyphs correctly. Patch from Savannah bug #23277. 2008-05-16 Werner Lemberg <wl@gnu.org> * docs/CHANGES: Updated. 2008-05-16 Sergey Tolstov <stolstov@esri.com> Improve support for WGL4 encoded fonts. * src/psnames/psmodule.c (WGL_EXTRA_LIST_SIZE): New macro. (ft_wgl_extra_unicodes, ft_wgl_extra_glyph_names, ft_wgl_extra_glyph_name_offsets): New arrays. (ps_check_wgl_name, ps_check_wgl_unicode): New functions. (ps_unicodes_init): Use them to add additional Unicode mappings. 2008-05-15 Werner Lemberg <wl@gnu.org> * src/psaux/t1decode.c (t1_decoder_parse_charstrings) <op_closepath>: `closepath' without a path is a no-op, not an error (cf. the PS reference manual). Reported by Martin McBride. 2008-05-15 Werner Lemberg <wl@gnu.org> * builds/toplevel.mk (CONFIG_GUESS, CONFIG_SUB): Updated. 2008-05-15 Werner Lemberg <wl@gnu.org> * src/type1/t1load.c (parse_subrs): Accept fonts with a subrs array which contains a single but empty entry. This is technically invalid (since it must end with `return'), but... Reported by Martin McBride. 2008-05-14 Werner Lemberg <wl@gnu.org> Finish fix of scaling bug of CID-keyed CFF subfonts. * include/freetype/internal/ftcalc.h, src/base/ftcalc.c (FT_Matrix_Multiply_Scaled, FT_Vector_Transform_Scaled): New functions. * src/cff/cffobjs.h (CFF_Internal): New struct. It is used to provide global hinting data for both the top-font and all subfonts (with proper scaling). * src/cff/cffobjs.c (cff_make_private_dict): New function, using code from `cff_size_init'. (cff_size_init, cff_size_done, cff_size_select, cff_size_request): Use CFF_Internal and handle subfonts. (cff_face_init): Handle top-dict and subfont matrices correctly; apply some heuristic in case of unlikely matrix concatenation results. This has been discussed with people from Adobe (thanks goes mainly to David Lemon) who confirm that the CFF specs are fuzzy and not correct. * src/cff/cffgload.h (cff_decoder_prepare): Add `size' argument. * src/cff/cffgload.c (cff_builder_init): Updated. (cff_decoder_prepare): Handle hints globals for subfonts. Update all callers. (cff_slot_load): Handling scaling of subfonts properly. * src/cff/cffparse.c (cff_parse_fixed_dynamic): New function. (cff_parse_font_matrix): Use it. * src/cff/cfftypes.h (CFF_FontDictRec): Make `units_per_em' FT_ULong. * docs/CHANGES: Document it. 2008-05-13 Werner Lemberg <wl@gnu.org> * src/winfonts/winfnt.c (fnt_face_get_dll_font, FNT_Face_Init): Handle case `face_index < 0'. * docs/CHANGES: Document it. 2008-05-04 Werner Lemberg <wl@gnu.org> First steps to fix the scaling bug of CID-keyed CFF subfonts, reported by Ding Li on 2008/03/28 on freetype-devel. * src/base/cff/cffparse.c (power_tens): New array. (cff_parse_real): Rewritten to introduce a fourth parameter which returns the `scaling' of the real number so that we have no precision loss. This is not used yet. Update all callers. (cff_parse_fixed_thousand): Replace with... (cff_parse_fixed_scaled): This function. Update all callers. 2008-05-03 Werner Lemberg <wl@gnu.org> * src/base/ftobjs.c (FT_Load_Glyph): Call the auto-hinter without transformation since it recursively calls FT_Load_Glyph. This fixes Savannah bug #23143. 2008-04-26 Werner Lemberg <wl@gnu.org> * include/freetype/internal/psaux.h (T1_BuilderRec): Mark `scale_x' and `scale_y' as obsolete since they aren't used. * src/psaux/psobjs.c (t1_builder_init): Updated. * src/cff/cffgload.h (CFF_Builder): Mark `scale_x' and `scale_y' as obsolete since they aren't used. * src/cff/cffgload.c (cff_builder_init): Updated. 2008-04-14 Werner Lemberg <wl@gnu.org> * src/pcf/pcfdrivr.c (PCF_Face_Init): Protect call to `FT_Stream_OpenLZW' with `FT_CONFIG_OPTION_USE_LZW'. From Savannah bug #22909. 2008-04-13 Werner Lemberg <wl@gnu.org> * src/psaux/psconv.c (PS_Conv_ToFixed): Increase precision if integer part is zero. 2008-04-01 Werner Lemberg <wl@gnu.org> Fix compilation with g++ 4.1 (with both `single' and `multi' targets). * src/base/ftobjs.c (FT_Open_Face): Don't define a variable in block which is crossed by a `goto'. * src/otvalid/otvalid.h (otv_MATH_validate): Add prototype. 2008-03-31 Werner Lemberg <wl@gnu.org> Fix support for subsetted CID-keyed CFFs. * include/freetype/freetype.h (FT_FACE_FLAG_CID_KEYED, FT_IS_CID_KEYED): New macros. * src/cff/cffobjs.c (cff_face_init): Set number of glyphs to the maximum CID value in CID-keyed CFFs. Handle FT_FACE_FLAG_CID_KEYED flag. * docs/CHANGES: Document it. Fix CFF font matrix calculation and improve precision. * src/cff/cffparse.c (cff_parse_real): Increase precision if integer part is zero. (cff_parse_font_matrix): Simplify computation of `units_per_em'; this prevents overflow also. Support FT_Get_CID_Registry_Ordering_Supplement for PS CID fonts. * src/cid/cidriver.c: Include FT_SERVICE_CID_H. (cid_get_ros): New function. (cid_service_cid_info): New service structure. (cid_services): Register it. 2008-03-23 Werner Lemberg <wl@gnu.org> Adjustments for Visual C++ 8.0, as reported by Rainer Deyke. * builds/compiler/visualc.mk (CFLAGS): Remove /W5. (ANSIFLAGS): Add _CRT_SECURE_NO_DEPRECATE. 2008-03-21 Laurence Darby <ldarby> * src/type1/t1objs.c (T1_Face_Init): Use `/Weight'. Patch from Savannah bug #22675. 2008-03-13 Derek Clegg <dclegg@apple.com> * src/truetype/ttgxvar.c (TT_Get_MM_Var): Fix named style loop. Patch from Savannah bug #22541. 2008-03-03 Masatoshi Kimura <VYV03354@nifty.ne.jp> * src/sfnt/ttcmap.c (tt_cmap14_char_map_nondef_binary, tt_cmap14_find_variant): Return correct value. (tt_cmap14_variant_chars): Fix check for `di'. 2008-02-29 Werner Lemberg <wl@gnu.org> * docs/CHANGES: Updated. 2008-02-29 Wolf Add build support for symbian platform. From Savannah bug #22440. * builds/symbian/: New files. 2008-02-21 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> src/base/ftmac.c (parse_fond): Fix a bug of PostScript font name synthesis. For any face of a specified FOND, always the name for the first face was used. Except of a FOND that refers multiple Type1 font files, wrong synthesized font names are not used at all, so this is an invisible bug. A few limit checks are added too. * builds/mac/ftmac.c: Ditto. 2008-02-21 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * builds/unix/configure.raw: Split compiler option to link Carbon frameworks to one option for CoreServices framework and another option for ApplicationServices framework. The split options can be managed by GNU libtool to avoid unrequired duplication when FreeType is linked with other applications. Suggested by Daniel Macks, Savannah bug #22366. 2008-02-18 Victor Stinner <victor.stinner@haypocalc.com> * src/truetype/ttinterp.c (Ins_IUP): Check number of points. Fix from Savannah bug #22356. 2008-02-17 Jonathan Blow <jon@number-none.com> * src/autofit/afloader.c (af_loader_load_g, af_loader_load_glyph): Check for valid callback pointers. 2008-02-15 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * src/base/ftmac.c (FT_New_Face_From_SFNT): Check the sfnt resource handle by its value instead of ResError(), fix provided by Deron Kazmaier. According to the Resource Manager Reference, GetResource(), Get1Resource(), GetNamedResource(), Get1NamedResource() and RGetResource() set noErr but return NULL handle when they can not find the requested resource. These functions never return undefined values, so it is sufficient to check if the handle is not NULL. * builds/mac/ftmac.c (FT_New_Face_From_SFNT): Ditto. 2008-02-14 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * src/base/ftbase.c: <ftmac.c> is replaced by "ftmac.c" as other inclusion styles. Now it always includes src/base/ftmac.c; builds/mac/ftmac.c is never included in any configuration. * builds/unix/configure.raw: Print warning if configure is executed with options to specify Carbon functionalities explicitly. * docs/INSTALL.MAC: Note that legacy builds/mac/ftmac.c is not included automatically and manual replacement is required. 2008-02-11 Werner Lemberg <wl@gnu.org> * builds/modules.mk (CLOSE_MODULE, REMOVE_MODULE), builds/detect.mk (dos_setup), builds/freetype.mk (clean_project_dos, distclean_project_dos): Don't use \ but $(SEP). Reported by Duncan Murdoch. 2008-01-18 Sylvain Pasche <sylvain.pasche@gmail.com> * src/base/ftlcdfil.c (_ft_lcd_filter_legacy): Updated comment to mention intra-pixel algorithm. * include/freetype/freetype.h (FT_Render_Mode): Mention that FT_Library_SetLcdFilter can be used to reduce fringes. 2008-01-16 Werner Lemberg <wl@gnu.org> * src/raster/ftraster.c (ft_black_render): Check `outline' before using it. Reported by Allan Yang. 2008-01-12 Werner Lemberg <wl@gnu.org> * src/raster/ftraster.c (FT_CONFIG_OPTION_5_GRAY_LEVELS): Remove. 2008-01-12 Allan Yang, Jian Hua - SH <Allan.Yang@fmc.fujitsu.com> * src/raster/ftraster.c (ft_black_init) [FT_RASTER_OPTION_ANTI_ALIASING]: Fix compilation. 2008-01-10 Werner Lemberg <wl@gnu.org> * src/truetype/ttgload.c (load_truetype_glyph): Handle the case where the number of contours in a simple glyph is zero (and which does contain an entry in the `glyf' table). This fixes Savannah bug #21990. 2008-01-04 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> Formatting suggested by Sean McBride. * builds/mac/ftmac.c: Formatting (tab expanded). * src/autofit/afindic.c: Ditto. * src/base/ftcid.c: Ditto. * src/base/ftmac.c: Ditto. 2007-12-30 Werner Lemberg <wl@gnu.org> * src/smooth/ftgrays.c (gray_raster_render): Check `outline' correctly. 2007-12-21 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> Improvement of POSIX resource-fork accessor to load unsorted references in a resource. In HelveLTMM (resource-fork PostScript Type1 font bundled with Mac OS X since 10.3.x), the appearance order of PFB chunks is not sorted; sorting the chunks by reference IDs is required. * include/freetype/internal/ftrfork.h (FT_RFork_Ref): New structure type to store a pair of reference ID and offset to the chunk. * src/base/ftrfork.c (ft_raccess_sort_ref_by_id): New function to sort FT_RFork_Ref by their reference IDs. (FT_Raccess_Get_DataOffsets): Returns an array of offsets that is sorted by reference ID. 2007-12-14 Werner Lemberg <wl@gnu.org> * src/cff/cffparse.c (cff_parse_real): Don't apply `power_ten' division too early; otherwise the most significant digit(s) of the final result are lost as the value is truncated to an integer. This fixes Savannah bug #21794 (where the patch has been posted too). 2007-12-06 Fix <4d876b82@gmail.com> Pass options from one configure script to another as-is (not expanded). This is needed for options like --includedir='${prefix}/include'. * builds/unix/detect.mk, configure: Prevent argument expansion in call to the (real) `configure' script. 2007-12-06 Werner Lemberg <wl@gnu.org> * src/truetype/ttgload.c (load_truetype_glyph): Fix compilation if TT_USE_BYTECODE_INTERPRETER isn't defined. 2007-12-06 Werner Lemberg <wl@gnu.org> There exist CFFs which contain opcodes for the Type 1 operators `hsbw' and `closepath' which are both invalid in Type 2 charstrings. However, it doesn't harm to support them. * src/cff/cffgload.c (CFF_Operator): Add `cff_op_hsbw' and `cff_op_closepath.' (cff_argument_counts): Ditto. (cff_decoder_parse_charstrings): Handle Type 1 opcodes 9 (closepath) and 13 (hsbw) which are invalid in Type 2 charstrings. 2007-12-06 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * src/base/ftrfork.c (raccess_guess_darwin_newvfs): New function to support new pathname syntax `..namedfork/rsrc' to access a resource fork on Mac OS X. The legacy syntax `/rsrc' does not work on case-sensitive HFS+. (raccess_guess_darwin_hfsplus): Fix a bug in the calculation of buffer size to store a pathname. * include/freetype/internal/ftrfork.h: Increment the number of resource fork guessing rule. 2007-12-06 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * builds/unix/configure.raw: Improve the compile tests to search Carbon functions. * builds/mac/ftmac.c: Import fixes for Carbon incompatibilities proposed by Sean McBride from src/base/ftmac.c (see 2007-11-16). 2007-12-06 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> The documents and comments for Mac OS X are improved by Sean McBride. * src/base/ftmac.c: Fix a comment. * include/freetype/ftmac.h: Ditto. * docs/INSTALL.MAC: Improve English and add comment on lowest system version specified by MACOSX_DEPLOYMENT_TARGET. 2007-12-04 Werner Lemberg <wl@gnu.org> * src/cff/cffload.c (cff_subfont_load): Don't use logical OR to concatenate error codes. * src/sfnt/ttsbit.c (Load_SBit_Range): Ditto. 2007-12-04 Graham Asher <graham.asher@btinternet.com> * src/truetype/ttobjs.c (tt_face_init): Don't use logical OR to concatenate error codes. 2007-12-04 Sean McBride <sean@rogue-research.com> * src/pfr/pfrgload.c (pfr_glyph_load_compound): Remove compiler warning. 2007-11-20 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> Fix MacOS legacy font support by Masatake Yamato on Mac OS X. It is not working since 2.3.5. In FT_Open_New(), if FT_New_Stream() cannot mmap() the specified file and cannot seek to head of the specified file, it returns NULL stream and FT_Open_New() returns the error immediately. On MacOS, most legacy MacOS fonts fall into such a scenario because their data forks are zero-sized and cannot be sought. To proceed to guessing of resource fork fonts, the functions for legacy MacOS font must properly handle the NULL stream returned by FT_New_Stream(). * src/base/ftobjs.c (IsMacBinary): Return error FT_Err_Invalid_Stream_Operation immediately when NULL stream is passed. (FT_Open_Face): Even when FT_New_Stream() returns an error, proceed to fallback. Originally, legacy MacOS font is tested in the cases of FT_Err_Invalid_Stream_Operation (occurs when data fork is empty) or FT_Err_Unknown_File_Format (occurs when AppleSingle header or .dfont header is combined). Now the case of FT_Err_Cannot_Open_Stream is included. * src/base/ftrfork.c (FT_Raccess_Guess): When passed stream is NULL, skip FT_Stream_Seek(), which seeks to the head of stream, and proceed to unit testing of raccess_guess_XXX(). FT_Stream_Seek() for a NULL stream causes a Bus error on Mac OS X. (raccess_guess_apple_double): Return FT_Err_Cannot_Open_Stream immediately if passed stream is NULL. (raccess_guess_apple_single): Ditto. 2007-11-16 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> Fix for Carbon incompatibilities since Mac OS X 10.5, proposed by Sean McBride. * doc/INSTALL.MAC: Comment on MACOSX_DEPLOYMENT_TARGET. * include/freetype/ftmac.h: Deprecate FT_New_Face_From_FOND and FT_GetFilePath_From_Mac_ATS_Name. Since Mac OS X 10.5, calling Carbon functions from a forked process is classified as unsafe by Apple. All Carbon-dependent functions should be deprecated. * src/base/ftmac.c: Use essential header files <CoreServices/CoreServices.h> and <ApplicationServices/ApplicationServices.h> instead of all-in-one header file <Carbon/Carbon.h>. Include <sys/syslimits.h> and replace HFS_MAXPATHLEN by Apple genuine macro PATH_MAX. Add fallback macro for kATSOptionFlagsUnRestrictedScope which is not found in Mac OS X 10.0. Multi-character constants ('POST', 'sfnt' etc) are replaced by 64bit constants calculated by FT_MAKE_TAG() macro. For the index in the segment of resource fork, new portable type ResourceIndex is introduced for better compatibility. This type is since Mac OS X 10.5, so it is defined as short when built on older platforms. (FT_ATSFontGetFileReference): If build target is only the systems 10.5 and newer, it calls Apple genuine ATSFontGetFileReference(). (FT_GetFile_From_Mac_ATS_Name): Return an error if system is 10.5 and newer or 64bit platform, because legacy type FSSpec type is removed completely.

(tt_size_init): Move most code into `tt_size_init_bytecode'. (tt_size_done): Move most code into `tt_size_done_bytecode'. (tt_size_reset): Move some code to `tt_size_ready_bytecode'. Don't extract the metrics table from the SFNT font file. Instead, reparse it on each glyph load. The runtime difference is not noticeable, and it can save a lot of heap memory when memory-mapped files are not used. * include/freetype/internal/tttypes.h (TT_FaceRec): Add members `horz_metrics_offset' and `vert_metrics_offset'. * src/sfnt/ttmtx.c (tt_face_load_hmtx, tt_face_get_metrics): Updated. * src/sfnt/ttcmap.c (tt_cmap4_validate): Slight optimization. Do not load the CFF index offsets into memory, since this wastes a lot of heap memory with large Asian CFF fonts. There is no significant performance loss. * src/cff/cffload.h: Add `cff_charset_cid_to_gindex' declaration. * src/cff/cfftypes.h (CFF_IndexRec): Add fields `start' and `data_size'. (CFF_CharsetRec): Add field `num_glyphs'. * src/cff/cffload.c (cff_index_read_offset, cff_index_load_offsets, cff_charset_cid_to_gindex): New functions. (cff_new_index): Renamed to... (cff_index_init): This. Update all callers. Updated -- some code has been moved to `cff_index_load_offsets'. (cff_done_index): Renamed to... (cff_index_done): This. Update all callers. (cff_index_get_pointers, cff_index_access_element): Updated to use stream offsets. (cff_charset_compute_cids): Set `num_glyphs' field. (cff_encoding_load): Updated. * src/cff/cffgload.c (cff_slot_load): Updated. 2007-01-04 David Turner <david@freetype.org> * docs/INSTALL.UNIX: Simplify some parts, add reference to autogen.sh and pointer to README.CVS. * README.CVS: Add common problem description and solution when running autogen.sh. * docs/INSTALL: Add reference to MacOS X. * docs/MAKEPP, docs/INSTALL.MAC: New documentation files. * docs/TODO: Remove obsolete items. * src/raster/ftraster.c: (TRaster_Instance): Replace it with... (TWorker): This. Remove `count_table' and `memory'. Make `grays' a pointer. (TRaster): New structure. (count_table): New static array. (RAS_ARGS, RAS_ARG, RAS_VARS, RAS_VAR, FT_UNUSED_RASTER, cur_ras, Vertical_Gray_Sweep_Step, ft_black_new, ft_black_done, ft_black_set_mode, ft_black_render): Updated. (ft_black_init): Don't initialize `count_table'. (ft_black_reset): Use the render pool. This saves about 6KB of heap space for each FT_Library instance. * src/smooth/ftgrays.c (TRaster): Replaced with... (TWorker): This. Remove `memory'. (TRaster): New structure. (RAS_ARG_, RAS_ARG, RAS_VAR_, RAS_VAR, ras, gray_render_line, gray_move_to, gray_line_to, gray_conic_to, gray_cubic_to, gray_render_span, gray_raster_render): Updated. (gray_raster_reset): Use the render pool. This saves about 6KB of heap space for each FT_Library instance. * src/sfnt/sfobjs.c, src/sfnt/ttkern.c, src/sfnt/ttkern.h, src/sfnt/ttmtx.c, src/sfnt/ttsbit.c, src/sfnt/ttsbit.h, src/truetype/ttpload.c, include/freetype/config/ftoption.h: Remove FT_OPTIMIZE_MEMORY macro (and code for !FT_OPTIMIZE_MEMORY) since the optimization is no longer experimental. * src/pshinter/pshalgo.c (psh_glyph_interpolate_normal_points): Remove a typo that results in no hinting and a memory leak with some large Asian CFF fonts. * src/base/ftobjs.c (FT_Done_Library): Remove a subtle memory leak which happens when FT_Done_Library is called with still opened CFF_Faces in it. We need to close all faces before destroying the modules, or else some bad things (memory leaks) may happen. 2007-01-02 Werner Lemberg <wl@gnu.org> * src/gxvalid/gxvkern.c (gxv_kern_subtable_fmt0_pairs_validate): Remove compiler warning. 2007-01-02 David Turner <david@freetype.org> * src/sfnt/sfobjs.c: Add documentation comment. 2006-12-31 Masatake YAMATO <jet@gyve.org> * src/gxvalid/gxvkern.c (gxv_kern_subtable_fmt0_pairs_validate): New function. Check uniqueness of the gid pairs. (gxv_kern_subtable_fmt0_validate): Move some code to `gxv_kern_subtable_fmt0_pairs_validate'. 2006-12-22 David Turner <david@freetype.org> * src/autofit/aflatin.c, src/truetype/ttgload.c: Remove compiler warnings. * builds/win32/visualc/freetype.vcproj: Add _CRT_SECURE_NO_DEPRECATE to avoid deprecation warnings with Visual C++ 8. 2006-12-16 Anders Kaseorg <anders@kaseorg.com> * src/base/ftlcdfil.c (FT_Library_SetLcdFilter) [FT_FORCE_LIGHT_LCD_FILTER]: Fix typo. 2006-12-15 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * include/freetype/internal/services/svotval.h: Add `volatile' to sync with the modification by Jens Claudius on 2006-08-22; cf. https://cvs.savannah.gnu.org/viewcvs/freetype/freetype2/src/otvalid/otvmod.c?r1=1.4&r2=1.5 2006-12-15 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * src/base/ftmac.c: Specialized for Mac OS X only. * builds/unix/ftconfig.in: Fixed for ppc64 missing Carbon framework. * builds/unix/configure.raw: Ditto. When explicit switches for FSSpec/FSRef/QuickDraw/ATS availability are given to configure, builds/mac/ftmac.c is used instead of default src/base/ftmac.c. 2006-12-15 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * builds/mac/ftmac.c: Copied src/base/ftmac.c for legacy system. * builds/mac/FreeType.m68k_cfm.make.txt: Fix to use builds/mac/ftmac.c instead of src/base/ftmac.c * builds/mac/FreeType.ppc_carbon.make.txt: Ditto. * builds/mac/FreeType.ppc_classic.make.txt: Ditto. * builds/mac/FreeType.m68k_far.make.txt: Ditto, and exclude gxvalid.c that cannot be built at present. 2006-12-15 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * src/base/ftobjs.c: Improvement of resource fork handler for POSIX, cf. https://lists.gnu.org/archive/html/freetype-devel/2006-10/msg00025.html (Mac_Read_sfnt_Resource): Count only `sfnt' resource of suitcase font format or .dfont, to simulate the face index number counted by ftmac.c. (IsMacResource): Return the number of scalable faces correctly. 2006-12-10 Werner Lemberg <wl@gnu.org> * builds/toplevel.mk (version): Protect against `distclean' target. 2006-12-09 Werner Lemberg <wl@gnu.org> * builds//def.mk, builds//detect.mk (CAT): Define to either `cat' or `type'. builds/freetype.mk (version): Extracted from freetype.h, using GNU make's built-in string functions. (refdoc): Use $(version) instead of static version number. 2006-12-08 Werner Lemberg <wl@gnu.org> * builds/toplevel.mk (dist): Extract version number from freetype.h. 2006-12-08 Vladimir Volovich <vvv@vsu.ru> * src/tools/apinames.c (State): Remove final comma in structure -- xlc v5 under AIX 4.3 doesn't like this. 2006-12-07 David Turner <david@freetype.org> * src/autofit/afloader.c (af_loader_load_g): Small adjustment to the spacing of auto-fitted glyphs. This only impacts rare cases (e.g., Arial Bold at rather small character sizes). 2006-12-03 Werner Lemberg <wl@gnu.org> * src/sfnt/rules.mk (SFNT_DRV_SRC): Add ttsbit0.c. 2006-12-01 Werner Lemberg <wl@gnu.org> * src/sfnt/sfobjs.c (tt_face_get_name): All Unicode strings are encoded in UTF-16BE.

Improve handling of remaining edges. 2006-11-22 Werner Lemberg <wl@gnu.org> Fix Savannah bug #15553. * src/truetype/ttgload.c (tt_loader_init): Re-execute the CVT program after a change from mono to grayscaling (and vice versa). Use correct constant for comparison to get `exec->grayscale'. 2006-11-18 Werner Lemberg <wl@gnu.org> Because FT_Load_Glyph expects CID values for CID-keyed fonts, the test for a valid glyph index must be deferred to the font drivers. This patch fixes Savannah bug #18301. * src/base/ftobjs.c (FT_Load_Glyph): Don't check `glyph_index'. * src/bdf/bdfdrivr.c (BDF_Glyph_Load), src/cff/cffgload.c (cff_slot_load), src/cid/cidgload.c (cid_slot_load_glyph), src/pcf/pcfdrivr.c (PCF_Glyph_Load), src/pfr/pfrobjs.c (pfr_slot_load), src/truetype/ttdriver.c (Load_Glyph), src/type1/t1gload.c (T1_Load_Glyph), src/winfonts/winfnt.c (FNT_Load_Glyph): Check validity of `glyph_index'. 2006-11-13 David Turner <david@freetype.org> * src/truetype/ttinterp.c (FIX_BYTECODE): Undefine. The interpreter `enhancements' are still too buggy for general use. * src/base/ftlcdfil.c: Add support for FT_FORCE_LIGHT_LCD_FILTER and FT_FORCE_LEGACY_LCD_FILTER at compile time. Define these macros when building the library to change the default LCD filter to be used. This is only useful for experimentation. * include/freetype/ftlcdfil.h: Update documentation. 2006-11-10 David Turner <david@freetype.org> * src/smooth/ftsmooth.c: API change for the LCD filter. The FT_LcdFilter value is an enumeration describing which filter to apply, with new values FT_LCD_FILTER_LIGHT and FT_LCD_FILTER_LEGACY (the latter implements the LibXft original algorithm which produces strong color fringes for everything except very-well hinted text). * include/freetype/ftlcdfil.h (FT_Library_SetLcdFilter): Change second parameter to an enum type. * src/base/ftlcdfil.c (USE_LEGACY): Define. (_ft_lcd_filter): Rename to... (_ft_lcd_filter_fir): This. Update parameters. (_ft_lcd_filter_legacy) [USE_LEGACY]: New filter function. (FT_Library_SetLcdFilter): Update parameters.

(FT_LibraryRec) [FT_CONFIG_OPTION_SUBPIXEL_RENDERING]: Add filtering callback and update other fields. * src/smooth/ftsmooth.c (ft_smooth_render_generic) [FT_CONFIG_OPTION_SUBPIXEL_RENDERING]: Update. Other minor improvements. * src/autofit/aflatin.c: Various tiny improvements that drastically improve the handling of serif fonts and of LCD/LCD_V hinting modes. (af_latin_hints_compute_edges): Fix typo. (af_latin_compute_stem_width): Take better care of diagonal stems. 2006-11-09 David Turner <david@freetype.org> * src/pshinter/pshalgo.c (psh_glyph_compute_inflections): Fix typo which created a variable-used-before-initialized bug. 2006-11-07 Zhe Su <james.su@gmail.com> * src/base/ftsynth.c (FT_GlyphSlot_Embolden): Handle vertical layout also. 2006-11-03 Werner Lemberg <wl@gnu.org> * src/base/ftcalc.c: Don't use `long long' but `FT_Int64'. 2006-11-02 David Turner <david@freetype.org> Add a few tweaks to better handle serif fonts. Add more debugging messages. * src/autofit/aflatin.c (af_latin_hints_compute_edges): Ignore segments that are less than 1.5 pixels high. This gets rid of many corner cases with serifs. (af_latin_align_linked_edge): Add logging message. (af_latin_hint_edges): Use AF_HINTS_DO_BLUES. Add logging messages. Handle AF_EDGE_FLAG flag specially. * src/autofit/afmodule.c [AF_DEBUG]: Add _af_debug, _af_debug_disable_blue_hints, and _af_debug_hints variables. * src/autofit/aftypes.h (AF_LOG) [AF_DEBUG]: Use _af_debug. Update external declarations. (af_corner_orientation, af_corner_is_flat): Replaced by... * include/freetype/internal/ftcalc.h (ft_corner_orientation, ft_corner_is_flat): These declarations. * src/autofit/afangles.c (af_corner_orientation, af_corner_is_flat): Comment out. Replaced by... * src/base/ftcalc.h (ft_corner_orientation, ft_corner_is_flat): These functions. Update all callers. (FT_Add64) [!FT_LONG64]: Simplify. * src/autofit/afhints.c: Include FT_INTERNAL_CALC_H. (af_direction_compute): Add a missing FT_ABS call. This bug caused production of garbage by missing lots of segments. * src/autofit/afhints.h (AF_HINTS_DO_BLUES): New macro. * src/autofit/afloader.c (af_loader_init, af_loader_done) [AF_DEBUG]: Set _af_debug_hints. * src/pshinter/pshalgo.c: Include FT_INTERNAL_CALC_H. (psh_corner_is_flat, psh_corner_orientation): Use ft_corner_is_flat and ft_corner_orientation. * src/gzip/inftrees.c (huft_build): Remove compiler warning. 2006-10-24 Werner Lemberg <wl@gnu.org> * src/cff/cffload.c (cff_encoding_load): Remove unused variable. * src/base/ftobjs.c (FT_Select_Charmap): Disallow FT_ENCODING_NONE as argument. 2006-10-23 Zhe Su <zsu@novell.com> * src/base/ftoutln.c (FT_Outline_Get_Orientation): Re-implement to better deal with broken Asian fonts with strange glyphs, having self-intersections and other peculiarities. The used algorithm is based on the nonzero winding rule. 2006-10-23 David Turner <david@freetype.org> Speed up the CFF font loader. With some large CFF fonts, FT_Open_Face is now more than three times faster. * src/cff/cffload.c (cff_get_offset): Removed. (cff_new_index): Inline functionality of `cff_get_offset'. (cff_charset_compute_cids, cff_charset_free_cids): New functions. (cff_charset_done): Call `cff_charset_free_cids'. (cff_charset_load): Call `cff_charset_compute_cids'. (cff_encoding_load) <Populate>: Ditto, to replace inefficient loop. * src/sfnt/ttmtx.c (tt_face_load_hmtx): Replace calls to FT_GET_XXX with FT_NEXT_XXX. Speed up the Postscript hinter, with more than 100% speed increase on my machine. * src/pshinter/pshalgo.c (psh_corner_is_flat, psh_corner_orientation): New functions. (psh_glyph_compute_inflections): Merge loops for efficiency. Use `psh_corner_orientation'. (psh_glyph_init): Use `psh_corner_is_flat'. (psh_hint_table_find_strong_point): Renamed to... (psh_hint_table_find_strong_points): This. Rewrite, adding argument to handle all points at once. Update all callers. (PSH_MAX_STRONG_INTERNAL): New macro.

Find native C compiler and pass it by CC_BUILD, and find suffix for native executable and pass it by EXEEXT_BUILD. Also suffix for target executable is passed by EXEEXT. * builds/unix/unix-cc.in (CCraw_build, E_BUILD): New variables to build `apinames' which runs on building system. They are set by CC_BUILD and EXEEXT_BUILD. * builds/exports.mk (APINAMES_EXE): Change the extension for apinames from the suffix for target (E) to that for building host (E_BUILD). 2006-10-12 Werner Lemberg <wl@gnu.org> * docs/INSTALL.UNX, docs/UPGRADE.UNX: Renamed to... * docs/INSTALL.UNIX, docs/UPGRADE.UNIX: This. Update all documents which reference those files. 2006-10-12 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * builds/unix/configure.raw (FT2_EXTRA_LIBS): New variable.

Add a new API to support color filtering of subpixel glyph bitmaps. In a default build, the function `FT_Library_SetLcdFilter' returns `FT_Err_Unimplemented_Feature'; you need to #define FT_CONFIG_OPTION_SUBPIXEL_RENDERING in ftoption.h to compile the real implementation. * include/freetype/ftlcdfil.h, src/base/ftlcdfil.c: New files. * include/freetype/internal/ftobjs.h (FT_Bitmap_LcdFilterFunc): New typedef.

Handle unknown othersubrs gracefully: count their operands and let the following pop operators push the operands as the results onto the Type1 stack. Improve handling of setcurrentpoint opcode. 2006-06-25 Jens Claudius <jens.claudius@yahoo.com> The Type 1 parser now skips over top-level procedures as required for a `Simplified Parser'.

This fixes Savannah bug #16669. * src/pfr/pfrobjs.c (pfr_face_init): Fix the computation of `face->num_glyphs' which missed the last glyph, due to the offset-by-1 computation, since the PFR format doesn't guarantee that glyph index 0 corresponds to the `missing glyph. This fixes Savannah bug #16668. 2006-05-25 Werner Lemberg <wl@gnu.org> * builds/unix/unix-cc.in (LINK_LIBRARY): Don't comment out `-no-undefined'.

This both speeds up loading the glyph vectors themselves and the auto-fitter module. We now use inline assembler code with GCC to implement `FT_MulFix', which is probably the most important function related to the engine's performance. The resulting speed-up is about 25%. * include/freetype/internal/tttypes.h (TT_LoaderRec): Add fields `cursor' and `limit'. * src/autofit/afangles.c (af_corner_is_flat, af_corner_orientation): New functions.

Reported by numerous people on the `freetype-devel' list. Without this fix, glyphs aren't properly aligned on a common baseline. On 64bit systems, `FT_Pos' expands to `long int', having a width of 64bit. `CF2_Fixed' expands to `int' which is normally 32bit wide on 64bit hosts also. Wrong casts filled up the blues arrays with incorrect values. Note that all blues values are accessed with the `cf2_blueToFixed' macro which handles the 64bit to 32bit conversion. * src/cff/cf2ft.h (cf2_getBlueValues, cf2_getOtherBlues, cf2_getFamilyBlues, cf2_getFamilyOtherBlues): Use `FT_Pos' for `data', not `CF2_Fixed'. * src/cff/cf2ft.c (cf2_getBlueValues, cf2_getOtherBlues, cf2_getFamilyBlues, cf2_getFamilyOtherBlues): Updated. * src/cff/cf2blues.c (cf2_blues_init): Updated. 2013-05-04 Werner Lemberg <wl@gnu.org> More fixes for clang's `sanitize' feature. * src/base/ftcalc.c (FT_DivFix): Use unsigned values for computations which use the left shift operator and convert to signed as the last step. * src/base/fttrigon.c (ft_trig_prenorm, FT_Vector_Rotate, FT_Vector_Length, FT_Vector_Polarize): Ditto. * src/cff/cffgload.c (cff_decoder_parse_charstrings): Simplify. * src/cff/cffload.c (cff_subfont_load): Fix constant. * src/cff/cffparse.c (cff_parse_integer, cff_parse_real, do_fixed, cff_parse_fixed_dynamic): Use unsigned values for computations which use the left shift operator and convert to signed as the last step. * src/cid/cidload.c (cid_get_offset): Ditto. * src/psaux/psconv.c (PS_Conv_ToFixed): Ditto. * src/psaux/t1decode.c (t1_decoder_parse_charstrings): Ditto. * src/truetype/ttinterp.c (TT_MulFix14, TT_DotFix14): Ditto. 2013-05-04 Werner Lemberg <wl@gnu.org> Fix errors reported by clang's `sanitize' feature. * include/freetype/internal/ftstream.h: Simplify and fix integer extraction macros. (FT_INT8_, FT_BYTE_I16, FT_BYTE_I32, FT_INT8_I16, FT_INT8_I32, FT_INT8_I32, FT_INT8_U32): Removed. (FT_PEEK_SHORT, FT_PEEK_LONG, FT_PEEK_OFF3, FT_PEEK_SHORT_LE, FT_PEEK_LONG_LE, FT_PEEK_OFF3_LE): Use unsigned values for computations and convert to signed as the last step. * src/cff/cf2fixed.h (cf2_intToFixed, cf2_fixedToInt, cf2_fracToFixed): Avoid shifts of negative values. (cf2_intToFrac, cf2_fixedToFrac, cf2_fixedTo26Dot6): Removed, unused. * src/cff/cf2intrp.c (cf2_interpT2CharString) <cf2_cmdEXTENDEDNMBR, default>: Use unsigned values for computations and convert to signed as the last step. Use proper types in tracing messages. * src/cff/cffgload.c (cff_decoder_parse_charstrings): Use unsigned values for computation of operands and convert to signed as the last step. Use proper type in tracing message. 2013-05-03 Werner Lemberg <wl@gnu.org> * src/cff/cf2blues.c: Remove dead code. 2013-05-02 Chris Liddell <chris.liddell@artifex.com> * src/cff/cffgload.c: Include FT_CFF_DRIVER_H. 2013-04-27 Werner Lemberg <wl@gnu.org> * docs/CHANGES: Updated. * README: Improved. 2013-04-13 Werner Lemberg <wl@gnu.org> [cff] Add a new Type 2 interpreter and hinter. This work, written by Dave Arnold <darnold@adobe.com> and fully integrated into FreeType by me, is a donation by Adobe in collaboration with Google. It is vastly superior to the old CFF engine, and it will replace it soon. Right now, it is still off by default, and you have to explicitly select it using the new `hinting-engine' property of the cff driver. For convenience, (most of) the new files are committed separately. * include/freetype/config/ftheader.h (FT_CFF_DRIVER_H): New macro. * include/freetype/ftcffdrv.h: New file to access CFF driver properties. * include/freetype/fterrdef.h (FT_Err_Glyph_Too_Big): New error code. * include/freetype/internal/fttrace.h: Add `cf2blues', `cf2hints', and `cf2interp'. * src/cff/cffgload.h (CFF_SubFont): New member `current_subfont'. * src/cff/cffobjs.h (CFF_DriverRec): New members `hinting_engine' and `no_stem_darkening'. * src/cff/cfftypes.h (CFF_FontRec): New member `cf2_instance'. * src/cff/cff.c: Include new files. * src/cff/cffdrivr.c (cff_property_set, cff_property_get): Handle `hinting-engine' and `no-stem-darkening' properties (only the Adobe engine listens to them). * src/cff/cffgload.c: Include `cf2ft.h'. (cff_decoder_prepare): Initialize `current_subfont'. (cff_build_add_point): Handle Adobe engine which uses 16.16 coordinates. (cff_slot_load): Handle FT_LOAD_NO_SCALE and FT_LOAD_NO_HINTING separately. Choose rendering engine based on `hinting_engine' property. * src/cff/cffload.c (cff_font_done): Call finalizer of the Adobe engine. * src/cff/cffobjs.c: Include FT_CFF_DRIVER_H. (cff_driver_init): Set default property values. * src/cff/rules.mk (CFF_DRV_SRC, CFF_DRV_H): Add new files. * src/cff/cf2.: New files, containing the Adobe engine. 2013-04-12 Werner Lemberg <wl@gnu.org> [cff] Minor code administration issues. * src/cff/cffgload.c (check_points): Rename to... (cff_check_points): ...this and make it FT_LOCAL. (cff_builder_add_point, cff_builder_add_point1, cff_builder_start_point, cff_builder_close_contour, cff_lookup_glyph_by_stdcharcode, cff_get_glyph_data, cff_free_glyph_data): Make them FT_LOCAL. * src/cff/cffgload.h: Updated. 2013-04-12 Werner Lemberg <wl@gnu.org> Add output bitmap checksums. Use `FT2_DEBUG=bitmap:3' for tracing. * src/base/md5.c, src/base/md5.h: New files, taken from https://openwall.info/wiki/people/solar/software/public-domain-source-code/md5 * include/freetype/internal/fttrace.h: Add `bitmap'. * src/base/ftobjs.c [FT_DEBUG_LEVEL_TRACE]: Include `md5.c' (FT_Render_Glyph_Internal) [FT_DEBUG_LEVEL_TRACE]: For tracing, convert resulting bitmap to a uniform format and compute a checksum. Use `bitmap' category for the tracing message. * src/base/rules.mk (BASE_H): Updated. * docs/LICENSE.TXT: Updated. 2013-04-12 Werner Lemberg <wl@gnu.org> [cff] Add framework for CFF properties. * include/freetype/internal/ftserv.h (FT_DEFINE_SERVICEDESCREC7): New macro. * src/cff/cffdrivr.c: Include FT_SERVICE_PROPERTIES_H. (cff_property_set, cff_property_get): New functions, still empty. Define `cff_service_properties' service. Update `cff_services'. * src/cff/cffpic.h: Include FT_SERVICE_PROPERTIES_H. (CFF_SERVICE_PROPERTIES_GET): New macro. (CffModulePIC): Add `cff_service_properties'. 2013-04-03 Werner Lemberg <wl@gnu.org> [bdf] Fix Savannah bug #38589. * src/bdf/bdflib.c (_bdf_readstream): Thinko. 2013-03-31 Werner Lemberg <wl@gnu.org> * configure: Use egrep, not grep. Problem reported Mojca Miklavec <mojca.miklavec.lists@gmail.com>. 2013-03-29 Werner Lemberg <wl@gnu.org> * include/freetype/ftlcdfil.h: Add description of color filtering. Based on a contribution from Antti S. Lankila <alankila@bel.fi> (Savannah bug #38607). 2013-03-23 Werner Lemberg <wl@gnu.org> [autofit] Minor. * src/autofit/afmodule.c (af_property_set): Typo. (af_autofitter_init, af_autofitter_done): Use cast. 2013-03-21 Werner Lemberg <wl@gnu.org> * configure: Automatically test for `gmake' also. Suggested by Mojca Miklavec <mojca.miklavec.lists@gmail.com>. 2013-03-21 Peter Breitenlohner <peb@mppmu.mpg.de> Respect CONFIG_SHELL from the environment. Some large packages using FreeType have to use a broken (deficient) /bin/sh. The configure scripts (as generated by Autoconf) are clever enough to find a better shell and put that one into the environment variable CONFIG_SHELL. If that environment variable is already set the script skips the test and assumes to be already running under a good shell. * builds/unix/detect.mk: Honour CONFIG_SHELL. * builds/unix/unix-def.in (SHELL): Define. 2013-03-21 Werner Lemberg <wl@gnu.org> Fix Savannah patch #7971. * configure: Handle MAKE environment variable also. 2013-03-17 Werner Lemberg <wl@gnu.org> Fix Savannah bug #38538. * builds/amiga/src/base/ftdebug.c, builds/win32/ftdebug.c, builds/wince/ftdebug.c (FT_Throw): Add function. 2013-03-17 Werner Lemberg <wl@gnu.org> [raster] Remove dead code. * src/raster/rastpic.c (ft_raster1_renderer_class_pic_init) src/smooth/ftspic.c (ft_smooth_renderer_class_pic_init): Do it. 2013-03-17 Werner Lemberg <wl@gnu.org> * src/pshinter/pshpic.h (GET_PIC): Use correct container. 2013-03-15 Werner Lemberg <wl@gnu.org> * include/freetype/ftmoderr.h: Fix commit from 2013-03-11. The previous version was not backward compatible. Reported by Behdad. 2013-03-14 Werner Lemberg <wl@gnu.org> /: Use FT_ERR_EQ, FT_ERR_NEQ, and FT_ERR where appropriate. FT_Err_XXX and friends are no longer directly used in the source code. 2013-03-14 Werner Lemberg <wl@gnu.org> New error management macros. * include/freetype/fterrors.h (FT_ERR_XCAT, FT_ERR_CAT): Move to... * include/freetype/fttypes.h: ... this file. (FT_ERR, FT_ERR_EQ, FT_ERR_NEQ, FT_MODERR_EQ, FT_MODERR_NEQ): New macros. * include/freetype/freetype.h: Updated. 2013-03-14 Werner Lemberg <wl@gnu.org> /: Use FT_Err_Ok only. This is a purely mechanical conversion. 2013-03-14 Werner Lemberg <wl@gnu.org> /: Use `FT_THROW'. This is essentially a mechanical conversion, adding inclusion of `FT_INTERNAL_DEBUG_H' where necessary, and providing the macros for stand-alone compiling modes of the rasterizer modules. To convert the remaining occurrences of FT_Err_XXX and friends it is necessary to rewrite the code. Note, however, that it doesn't harm if some cases are not handled since FT_THROW is a no-op. 2013-03-13 Werner Lemberg <wl@gnu.org> Introduce `FT_THROW' macro. The idea is to replace code like return FT_Err_Foo_Bar; or return CFF_Err_Foo_Bar; with return FT_THROW( Foo_Bar ); The FT_THROW macro has two functions: . It hides the module specific prefix. . In debug mode, it calls the empty function `FT_Throw' which can be thus used to set a breakpoint. * include/freetype/internal/ftdebug.h (FT_THROW): New macro. (FT_Throw): New prototype. * src/base/ftdebug.c (FT_Throw): New function. 2013-03-12 Werner Lemberg <wl@gnu.org> Remove `FT_KEEP_ERR_PREFIX'. The idea is to always have FT_ERR_PREFIX available internally. * include/freetype/fterrors.h: Use FT2_BUILD_LIBRARY to guard undefinition of FT_ERR_PREFIX * src/gxvalid/gxverror.h, src/otvalid/otverror.h, src/sfnt/sferrors.h: Updated. 2013-03-11 Werner Lemberg <wl@gnu.org> [gxvalid] Fix module error. * src/gxvalid/gxverror.h (FT_ERR_BASE): Define as FT_Mod_Err_GXvalid. * include/freetype/ftmoderr.h: Add module error for `GXvalid'. 2013-03-11 Werner Lemberg <wl@gnu.org> Always use module related error codes. * src/cff/cffobjs.c (cff_face_init), src/type1/t1objs.c (T1_Face_Init), src/type42/t42objs.c (T42_Face_Init): Use `FT_ERROR_BASE'. * src/type1/t1load.c (parse_encoding): Use T1_Err_Unknown_File_Format. 2013-03-08 Werner Lemberg <wl@gnu.org> [cff] Set `linear{Hori,Vert}Advance' for embedded bitmaps also. Problem reported by Khaled Hosny <khaledhosny@eglug.org>. * src/cff/cffgload.c (cff_slot_load): Implement it. 2013-02-23 Alexei Podtelezhnikov <apodtele@gmail.com> [base] Fix commit ab02d9e8. * src/base/ftbbox.c (BBox_Cubic_Check): Change scaling to msb of 22. 2013-02-19 Alexei Podtelezhnikov <apodtele@gmail.com> [base] New bisecting BBox_Cubic_Check (disabled). * src/base/ftbbox.c (BBox_Cubic_Check): New bisecting algorithm for extremum search built around simple condition that defines which half contains the extremum. 2013-02-18 Alexei Podtelezhnikov <apodtele@gmail.com> [tools] Update BBox testing tool. * src/tools/test_bbox.c: Add another cubic outline with exact BBox. (REPEAT): Increase the number of benchmarking cycles. (profile_outline): Tweak output formatting. 2013-02-02 Werner Lemberg <wl@gnu.org> Fix Savannah bug #38235. * builds/unix/configure.raw: Don't generate `freetype-config' and `freetype.pc'. * builds/unix/unix-def.in (FT2_EXTRA_LIBS, LIBBZ2, LIBZ, build_libtool_libs, ft_version): New variables to be substituted. (freetype-config, freetype.pc): New rules to generate those files. * builds/unix/freetype-config.in: Remove code for handling `rpath'. The use of $rpath has been accidentally removed in a patch from 2009-12-22, and apparently noone has missed it since. Use `%' instead of `@' as a variable substitution marker. Use quotes. * builds/unix/freetype.in: Use `%' instead of `@' as a variable substitution marker. Use quotes. 2013-02-07 Werner Lemberg <wl@gnu.org> * src/truetype/ttobjs.c (tt_size_run_prep): Reset more GS variables. BTW, Greg agrees that the OpenType specification is missing the list of GS variables which will always be reset to the default values after the `prep' table has been executed. 2013-02-06 Werner Lemberg <wl@gnu.org> * src/truetype/ttobjs.c (tt_size_run_prep): Reset reference points. Up to now, we simply took a snapshot of the Graphics State after the `prep' table has been executed, and right before a glyph's bytecode was run it got reloaded. However, as Greg Hitchcock has told us in private communication, reference points get reset to zero in the MS rasterizer and we follow in due course. While reasonable, this is undocumented behaviour. Most notably, this fixes the rendering of Arial's `x' glyph in subpixel hinting mode. 2013-02-05 Werner Lemberg <wl@gnu.org> [truetype] A better fix for Savannah bug #38211. * src/truetype/ttinterp.c (Ins_IP): Implement identical behaviour to MS rasterizer if rp1 == rp2 (confirmed by Greg Hitchcock). 2013-02-01 Alexei Podtelezhnikov <apodtele@gmail.com> [pcf] Streamline parsing of PCF encoding table. * src/pcf/pcfread.c (pcf_get_encodings): Use simpler double for-loop. Reallocate array instead of using temporary storage. 2013-02-01 Werner Lemberg <wl@gnu.org> Fix Savannah bug #38227. * builds/unix/freetype-config.in: Set LC_ALL. 2013-02-01 Werner Lemberg <wl@gnu.org> Fix Savannah bug #38221. This complements commit 83c0ebab. * src/base/ftcalc.c (FT_MulDiv_No_Round): Don't enclose with `TT_USE_BYTECODE_INTERPRETER'. 2013-02-01 Werner Lemberg <wl@gnu.org> [truetype] Fix Savannah bug #38211. * src/truetype/ttinterp.c (Ins_IP): Make FreeType behave identical to other interpreters if rp1 == rp2 (which is invalid). 2013-01-28 Alexei Podtelezhnikov <apodtele@gmail.com> [base] Small optimization of BBox calculation. * src/base/ftbbox.c (BBox_Cubic_Check): Use FT_MSB function in scaling algorithm. 2013-01-26 Infinality <infinality@infinality.net> [truetype] Minor formatting fix. * src/truetype/ttinterp.c: Updated.

(ALWAYS_SKIP_DELTAP_Rules): Remove rule for Trebuchet MS. (sph_set_tweaks): Fix `rasterizer_version' logic. 2013-01-26 Infinality <infinality@infinality.net> [truetype] Align more to ClearType whitepaper for sph. * include/freetype/internal/tttypes.h (TT_FaceRec): Add flags for detected opcode patterns and compatibility mode. * src/truetype/ttgload.c (tt_loader_init): Complete conditional. * src/truetype/ttinterp.c: Updated. Remove SPH_DEBUG and replace with FT_TRACE7. (DO_RS): More conditions. (Ins_FDEF): Add more opcode detection patterns. More specific conditions when flagging an fdef. Make compatibility mode only turn on when delta fdefs are found. (Ins_CALL, Ins_LOOPCALL): Set flags for currently executed fdef. (Ins_SHPIX): Remove logic to handle ttfautohinted fonts. Simplify conditionals where possible. Use `&' instead of `%' operator for dumb compilers. (Ins_MIAP): Adjust twilight zone conditional. Ensure `ignore_x_mode' is on when testing sph conditionals. (Ins_MIRP): Ensure `ignore_x_mode' is on when testing sph conditionals. Do cvt cutin always when `ignore_x_mode' is active. Remove test for ttfautohinted fonts. (Ins_DELTAP): Ensure `ignore_x_mode' is on when testing sph conditionals. Do cvt cutin always when `ignore_x_mode' is active. Remove test for ttfautohinted fonts. Use `&' instead of `%' operator for dumb compilers. (Ins_GETINFO): Remove SPH_DEBUG and replace with FT_TRACE7. * src/truetype/ttinterp.h: Updated. (TT_ExecContextRec): Remove compatibility_mode variable. Add variable to indicate when executing in special fdefs for sph. * src/truetype/ttobjs.h: Updated. (TT_DefRecord): Add flags to identify special fdefs for sph. (TT_SizeRec): Remove unnecessary ttfautohinted variable. * src/truetype/ttsubpix.c: Updated. (COMPATIBILITY_MODE_Rules): Remove all. Auto-detected now. (PIXEL_HINTING_Rules): Remove all. Unnecessary after fixes. (SKIP_NONPIXEL_Y_MOVES_Rules): Remove Ubuntu. (SKIP_NONPIXEL_Y_MOVES_Rules_Exceptions): Add Arial Bold `N'. (SKIP_OFFPIXEL_Y_MOVES_Rules): Remove all. Happens automatically now. (ROUND_NONPIXEL_Y_MOVES_Rules): Remove Ubuntu. (ROUND_NONPIXEL_Y_MOVES_Rules_Exceptions): Remove all. (NORMAL_ROUND_Rules): Remove Verdana. (NO_DELTAP_AFTER_IUP_Rules): Remove all. (sph_set_tweaks): Performance fix. Don't run prep always. Adjust conditional for sph_compatibility_mode. * src/truetype/ttsubpix.h: Add new fdef flags for sph. 2013-01-23 Alexei Podtelezhnikov <apodtele@gmail.com> [base] Fix broken emboldening at small sizes. * src/base/ftoutln.c (FT_Outline_EmboldenXY): Do not attempt to normalize zero-length vectors. 2013-01-25 Werner Lemberg <wl@gnu.org> Fix Savannah bug #38167. This fixes commit 83c0ebab from 2012-06-27. * src/truetype/ttinterp.h: s/TT_CONFIG_OPTION_BYTECODE_INTERPRETER/TT_USE_BYTECODE_INTERPRETER/. 2013-01-25 Xi Wang <xi.wang@gmail.com> [sfnt] Fix broken pointer overflow checks. Many compilers such as gcc and clang optimize away pointer overflow checks `p + n < p', because pointer overflow is undefined behavior. Use a safe form `n > p_limit - p' instead. Also avoid possible integer overflow issues, for example, using `num_glyphs > ( p_limit - p ) / 2' rather than `num_glyphs * 2' given a large `num_glyphs'. * src/sfnt/ttsbit0.c (tt_sbit_decoder_load_image): Implement it. 2013-01-25 Werner Lemberg <wl@gnu.org> [base] Fix `make multi'. * src/base/ftoutln.c, src/base/fttrigon.c: Include FT_INTERNAL_CALC_H. 2013-01-25 David 'Digit' Turner <digit@google.com> [truetype] Fix C++ compilation. * src/truetype/ttsubpix.h: Updated. (SPH_X_SCALING_RULES_SIZE): Moved and renamed to... * src/truetype/ttsubpix.c (X_SCALING_RULES_SIZE): This. (sph_X_SCALING_Rules): Removed. (scale_test_tweak): Make function static.

This patches fixes many issues with the ttsubpix implementation. 1. Data tables are defined, instead of declared, in the header, and thus copied into each source file that includes it. 2. These tables were defined as global, mutable, visible variables, and thus costing private RAM to every process that loads the library (> 50 KB / process, this is huge!). Additionally, this also made the library export the symbols completely needlessly. 3. Missing `sph_' and `SPH_' prefixes to some of the definitions. Note that this doesn't try to fix the incredibly inefficient storage format for the data tables used by the code. This one will require another pass in the future. * src/truetype/ttinterp.h (MAX_NAME_SIZE, MAX_CLASS_MEMBERS): Renamed to... (SPH_MAX_NAME_SIZE, SPH_MAX_CLASS_MEMBERS): This. Update all users.

Unit vector components are stored as 2.14 fixed-point numbers. In order to calculate all 14 bits accurately, a short vector to be normalized has to be upscaled to at least 14 bits before its length is calculated. This has been safe since accurate CORDIC algorithms were adopted. * src/truetype/ttinterp.c (Normalize): Scale short vectors by 0x4000. 2013-01-12 Alexei Podtelezhnikov <apodtele@gmail.com> [truetype] Kill very old vector normalization hacks. Back in the days, vector length calculations were not very accurate and the vector normalization function, Normalize, had to meticulously correct the errors for long vectors [commit b7ef2b096867]. It was no longer necessary after accurate CORDIC algorithms were adopted, but the code remained. It is time to kill it. * src/truetype/ttinterp.c (Normalize): Remove error compensation. (TT_VecLen): Remove any mention of old less accurate implementation. 2013-01-11 Werner Lemberg <wl@gnu.org> Disable FT_CONFIG_OPTION_OLD_INTERNALS.

FreeType used to rely on a 24-step iteration CORDIC algorithm to calculate trigonometric functions and rotate vectors. It turns out that once the vector is in the right half-plane, the initial rotation by 63 degrees is not necessary. The algorithm is perfectly capable to converge to any angle starting from the second 45 degree rotation. This patch removes the first rotation and makes it a 23-step CORDIC algorithm. * src/base/fttrigon.c (FT_TRIG_SCALE, FT_TRIG_COSCALE): Update macro values.

Add logic to handle ttfautohinted fonts. 2012-12-16 Werner Lemberg <wl@gnu.org> [sfnt] Fix Savannah bug #37936. * src/sfnt/ttload.c (tt_face_load_gasp): Avoid memory leak. 2012-12-15 Alexei Podtelezhnikov <apodtele@gmail.com> [base] Fix 11-year old bug. Since the initial commit (ebe85f59) the value of FT_TRIG_SCALE has always been slightly less than the correct value, which has been given in the comment as a hexadecimal. As a result, vector lengths were underestimated and rotated vectors were shortened. * src/base/fttrigon.c (FT_TRIG_SCALE): Fix macro value. 2012-12-15 Werner Lemberg <wl@gnu.org> [bdf] Fix Savannah bug #37907. * src/bdf/bdflib.c (_bdf_parse_glyphs) <ENCODING>: Normalize negative second parameter of `ENCODING' field also. 2012-12-15 Werner Lemberg <wl@gnu.org> [bdf] Fix Savannah bug #37906. * src/bdf/bdflib.c (_bdf_parse_glyphs) <ENCODING>: Use correct array size for checking `glyph_enc'. 2012-12-15 Werner Lemberg <wl@gnu.org> [bdf] Fix Savannah bug #37905. * src/bdf/bdflib.c (_bdf_parse_start) <STARTPROPERTIES>: Reset `props_size' to zero in case of allocation error; this value gets used in a loop in `bdf_free_font'. 2012-12-10 Alexei Podtelezhnikov <apodtele@gmail.com> [truetype] Scale F_dot_P down. The dot product between freeVector and projVector or cosine of the angle between these FT_F2Dot14 unit vectors used to be scaled up by 4 and routinely occupied 32 bits in an FT_Long field F_dot_P. This patch scales the value down by 2^14 instead, which simplifies its use throughout the bytecode interpreter. This does not lead to the loss of precision because the lower bits are unreliable anyway. Consider two unit vectors (1,0) and (.6,.8) for which the true value of F_dot_P is .6 * 0x40000000 = 0x26666666. These vectors are stored as (0x4000,0) and (0x2666,0x3333) after rounding and F_dot_P is assigned 0x26660000. The lower bits were already lost while rounding the unit vector components. Besides code simplification, this change can lead to better performance when FT_MulDiv with the scaled-down F_dot_P is less likely to use the costly 64-bit path. We are not changing the type of F_dot_P to FT_F2Dot14 at this point. * src/truetype/ttinterp.c (Compute_Funcs): Scale F_dot_P down by 14 bits and modify its use accordingly. (Direct_Move, Direct_Move_Orig, Compute_Point_Displacement): Modify the use of F_dot_P field. * src/truetype/ttobjs.c (tt_size_run_fpgm): Change arbitrary assignment of F_dot_P to its theoretical maximum in case we decide to scale back its type later. 2012-12-09 Johnson Y. Yan <yinsen_yan@foxitsoftware.com> [type1] Another fix for 2012-09-17 commit. * src/type1/t1parse.c (T1_Get_Private_Dict) <found>: Correctly set `limit' value. 2012-12-06 Alexei Podtelezhnikov <apodtele@gmail.com> [truetype] Tweak the previous commit. * src/truetype/ttinterp.c (Current_Ratio): Put unit vector components as the second TT_MulFix14 arguments.

This is an improved version of a similar fix contained in the so-called `Infinality patch', taken from http://www.infinality.net/fedora/linux/zips/freetype-infinality-2.4.10-20120616_01-x86_64.tar.bz2 which addresses various enhancements of the auto-hinter. Without properties to control a module's metadata it wasn't possible to adapt the patches because everything was originally controlled by environment variables which I consider not suitable in general. A patch to control `increase_x_height' follows. * src/autofit/afglobal.h (AF_PROP_INCREASE_X_HEIGHT_MIN, AF_PROP_INCREASE_X_HEIGHT_MAX): New macros. (AF_FaceGlobalsRec): Add `increase_x_height' member. * src/autofit/afglobal.c (af_face_globals_new): Initialize it. * src/autofit/aflatin.c (af_latin_metrics_scale_dim), * src/autofit/aflatin2.c (af_latin2_metrics_scale_dim): Implement handling of `increase_x_height'. 2012-09-18 Werner Lemberg <wl@gnu.org> [autofit] Add hierarchical property access to some structures. * src/autofit/afglobal.h: Include `afmodule.h'.

The subpixel hinting patch contained the concept of an adjustable number of gridlines per pixel. This is no longer used due to x being completely ignored instead. This will return some of the code to its existing state prior to the original Infinality commit. * include/freetype/internal/ftobjs.h (FT_PIX_FLOOR_GRID, FT_PIX_ROUND_GRID, FT_PIX_CEIL_GRID): Removed. * src/truetype/ttinterp.c: Updated.

(Move_Zp2_Point, Ins_SHPIX, Ins_MSIRP, Ins_MDAP, Ins_MIAP, Ins_MDRP, Ins_MIRP): Perform Round_None instead of calling a modified rounding function. Remove gridlines_per_pixel. Create a local variable to store control value cutin. Simplify the conditional for ignore_x_mode. Adjust rounding calls to pass only two values. 2012-06-25 Werner Lemberg <wl@gnu.org> [cff] Fix Savannah bug #36705. Handle numbers like 2.001 correctly. * src/cff/cffparse.c (cff_parse_real): Avoid negative values for `shift'. 2012-06-18 Infinality <infinality@infinality.net> [truetype] Support subpixel hinting. This is the large, famous `Infinality' patch to support ClearType bytecode which has been available from http://www.infinality.net/blog/ for some time, and which has been refined over the last years. While still experimental, it is now mature enough to be included directly into FreeType. Most of the code is based on the ClearType whitepaper written by Greg Hitchcock https://www.microsoft.com/typography/cleartype/truetypecleartype.aspx which gives a detailed overview of the necessary changes to the Microsoft rasterizer so that older fonts are supported. However, a lot of details are still missing, and this patches provides a framework to easily handle rendering issues down to the glyph level of certain fonts. Note that ClearType support is not completely implemented! In particular, full support for the options `compatible_widths', `symmetrical_smoothing, and `bgr' (via the GETINFO bytecode instruction) is missing. * src/truetype/ttsubpix.c: New file, providing code to handle `tweaks', this is, rules for certain glyphs in certain fonts (including wildcards) which need a special treatment. * src/truetype/ttsubpix.h: New file, holding the tweaking rules. * include/freetype/config/ftoption.h, src/devel/ftoption.h (TT_CONFIG_OPTION_SUBPIXEL_HINTING): New macro. * include/freetype/internal/ftobjs.h (FT_PIX_FLOOR_GRID, FT_PIX_ROUND_GRID, FT_PIX_CEIL_GRID): New macros. * src/truetype/truetype.c [TT_USE_BYTECODE_INTERPRETER]: Include `ttsubpix.c'. * src/truetype/ttgload.c: Include `ttsubpix.h'.

[Where necessary, changes below are guarded by TT_CONFIG_OPTION_SUBPIXEL_HINTING.] (Direct_Move, Direct_Move_X): Extended. (Round_None, Round_To_Grid, Round_To_Half_Grid, Round_Down_To_Grid, Round_Up_To_Grid, Round_To_Double_Grid, Round_Super, Round_Super_45, SetSuperRound): Add parameter to handle the number of grid lines per pixel.

Update all callers using `IS_INCREMENTAL'. 2012-03-11 Werner Lemberg <wl@gnu.org> [autofit] Return correct linear advance width values. This was quite a subtle bug which accidentally showed up with glyph `afii10023' of arial.ttf (version 2.76). This glyph is a composite; the first component, `E', has an advance width of 1366 font units, while the advance width of the composite itself (which looks like uppercase `E' with dieresis) is 1367 font units. I think this is actually a bug in the font itself, because there is no reason that this glyph has not the same width as uppercase `E' without the dieresis. Anyway, it helped identify this problem. Using the TrueType hinter, the correct value (1367) of `afii10023' was returned, but the autohinter mysteriously returned 1366. Digging in the code showed that the autohinter recursively calls FT_Load_Glyph to load the glyph, adding the FT_LOAD_NO_SCALE load flag. However, the `linearHoriAdvance' field is still returned as a scaled value. To avoid scaling twice, the old code in autofit reset `linearHoriAdvance', using the `horiAdvance' field. This seemed to work since FT_LOAD_NO_SCALE was in use, but it failed actually, because `horiAdvance' is defined as the distance of the first subglyph's phantom points, which in turn are initialized using the advance width of the first subglyph. And as the given example shows, these widths can differ. * src/autofit/afloader.c (af_loader_load_g): Temporarily set FT_LOAD_LINEAR_DESIGN while calling FT_Load_Glyph to get unscaled values for the linear advance widths. 2012-03-10 Werner Lemberg <wl@gnu.org> [truetype] Fix SSW instruction. * src/truetype/ttinterp.c (DO_SSW): SSW does use font units.

Originally FT_DEFINE_{DRIVER,MODULE,RENDERER}() macros were designed to declare xxx_pic_{free,init} by themselves. Because these macros are used at the end of the module interface (e.g. ttdriver.c) and the wrapper source to build a module as a single object (e.g. truetype.c) includes the PIC file (e.g. ttpic.c) before the module interface, these macros are expanded AFTER xxx_pic_{free,init} body when the modules are built as single object. The declaration after the implementation causes the redundant declaration warnings, so the declarations are moved to module PIC headers (e.g. ttpic.h). Separating to other header files are needed for multi build. * include/freetype/internal/ftdriver.h (FT_DEFINE_DRIVER): Remove class_##_pic_free and class_##_pic_init declarations. * include/freetype/internal/ftobjs.h (FT_DEFINE_RENDERER, FT_DEFINE_MODULE): Ditto. * src/base/basepic.h: Insert a comment and fix coding style. * src/autofit/afpic.h: Declare autofit_module_class_pic_{free, init}. * src/cff/cffpic.h: Declare cff_driver_class_pic_{free,init}. * src/pshinter/pshpic.h: Declare pshinter_module_class_pic_{free, init}. * src/psnames/pspic.h: Declare psnames_module_class_pic_{free, init}. * src/raster/rastpic.h: Declare ft_raster{1,5}_renderer_class_pic_{free,init} * src/sfnt/sfntpic.h: Declare sfnt_module_class_pic_{free,init}. * src/smooth/ftspic.h: Declare ft_smooth_{,lcd_,lcdv_}renderer_class_pic_{free,init}. * src/truetype/ttpic.h: Declare tt_driver_class_pic_{free,init}. 2012-01-15 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> Make pspic.c to include module error header to fix multi build. * src/psnames/pspic.c: Include `psnamerr.h'. 2012-01-14 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> [base] Fix a dereference of uninitialized variable in PIC mode. * src/base/ftglyph.c (FT_Glyph_To_Bitmap): `glyph' must be set before dereferring to obtain `library'.

Originally FT_MACINTOSH was a pure auto macro and DARWIN_NO_CARBON was a configurable macro to disable Carbon-dependent code. Because now configure script sets DARWIN_NO_CARBON by default and disables Darwin & Carbon-dependent codes, these macros can be unified. FT_MACINTOSH (undefined by default) is kept and DARWIN_NO_CARBON (defined by default) is removed, because DARWIN_NO_CARBON violates FT_XXX naming convention of public macros, and a macro configured by default is not portable for the building without configure (e.g. make devel). * builds/unix/configure.raw: Define FT_MACINTOSH if Carbon-based old Mac font support is requested and Carbon is available. * builds/unix/ftconfig.in: Undefine FT_MACINTOSH when the support for Mac OS X without Carbon (e.g. Mac OS X 10.4 for ppc64) is requested. * include/freetype/config/ftconfig.in: Ditto. * builds/vms/ftconfig.h: Ditto. * src/base/ftbase.h: Remove DARWIN_NO_CARBON. * src/base/ftbase.c: Ditto. * src/base/ftobjs.c: Ditto. * src/base/ftrfork.c: Ditto. * src/base/ftmac.c: Compile the body if FT_MACINTOSH is defined (same with TT_USE_BYTECODE_INTERPRETER in ttinterp.c). * builds/mac/ftmac.c: Ditto. * builds/mac/FreeType.m68k_cfm.make.txt: Define FT_MACINTOSH. * builds/mac/FreeType.m68k_far.make.txt: Ditto. * builds/mac/FreeType.ppc_classic.make.txt: Ditto. * builds/mac/FreeType.ppc_carbon.make.txt: Ditto. 2011-11-30 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> Fix Savannah bug #34728 (`make devel' on Mac OS X). * builds/toplevel.mk: Check `/dev/null' to identify the Unix- like systems without `init' nor `hurd' (e.g. Mac OS X >= 10.4). * builds/unix/detect.mk: Ditto. 2011-11-30 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> [apinames] Fix the overflow of signed integer hash. * src/tools/apinames.c (names_add): Change the type of `h' from int to unsigned int, to prevent undefined behaviour in the overflow of signed integers (overflow of unsigned int is defined to be wrap around).

Note, however, that this change is quite expensive since it increases the size of three arrays by almost 400kByte in total. The right fix is to replace the logic with something smarter. Additionally, there exist very old BDFs for three-byte CCCII encoding which exceeds the range of Unicode (another reason to have a smarter logic). * src/bdf/bdf.h (bdf_font_t): Increase size of `nmod' and `umod' arrays. * src/bdf/bdflib.c (bdf_parse_t): Increase size of `have' array. 2011-11-27 Werner Lemberg <wl@gnu.org> [bdf] Improve tracing. * src/bdf/bdflib.c (DBGMSG1, DBGMSG2): New macros.

The main problems ----------------- o If FT_STROKER_LINEJOIN_BEVEL was specified, unlimited miter joins (not bevel joins) were generated. Indeed, the meanings of `miter' and `bevel' were incorrectly reversed (consistently) in both the code and comments. o The way bevel joins were constructed (whether specified explicitly, or created as a result of exceeding the miter limit) did not match what is required for stroked text in PostScript or PDF. The main fixes -------------- o The behaviour of FT_STROKER_LINEJOIN_BEVEL has been corrected. o A new line join style, FT_STROKER_LINEJOIN_MITER_FIXED, has been introduced to support PostScript and PDF miter joins. o FT_STROKER_LINEJOIN_MITER_VARIABLE has been introduced as an alias for FT_STROKER_LINEJOIN_MITER. Additionally, a variety of stroking errors have been fixed. These would cause various artifacts (including points `at infinity'), especially when stroking poor quality fonts. See https://lists.gnu.org/archive/html/freetype-devel/2011-07/msg00001.html for example documents. The FreeType stroker now produces results very similar to that produced by GhostScript and Distiller for these fonts. Other problems -------------- The following problems have been resolved: o Inside corners could be generated incorrectly. Intersecting the inside corner could cause a missing triangular area and other effects. The intersection point can only be used if the join is between two lines and both lines are long enough. The `optimization' condition in `ft_stroker_inside' has been corrected; this requires the line length to be passed into various functions and stored in `FT_StrokerRec'. o Incorrect cubic curves could be generated. The angle calculations in `FT_Stroker_CubicTo' have been corrected to handle the case of the curve crossing the +/-PI direction. o If the border radius was greater than the radius of curvature of a curve, then the negative sector would end up outside (not inside) the border. This situation is now recognized and the negative sector is circumnavigated in the opposite direction. (If round line joins are being used, this code is disabled because the line join will always cover the negative sector.) o When a curve is split, the arcs may not join smoothly (especially if the curve turns sharply back on itself). Changes in direction between adjacent arcs were not handled. A round corner is now added if the deviation from one arc to the next is greater than a suitable threshold. o The current direction wasn't retained if a the outline contained a zero length lineto or a curve that was determined to be `basically a point'. This could cause a spurious join to be added. o Cubics with close control points could be mishandled. All eight cases are now distinguished correctly. Other improvements ------------------ o Borders for cubic curves could be too `flat'. FT_SMALL_CUBIC_THRESHOLD has been reduced a little to prevent this. o The handling and use of movable points has been simplified a little. o Various values are now computed only if the results are actually needed. o The directions of the outer and inner borders have been swapped, as recommended by Graham Asher. * src/base/ftstroke.c: Revised. * include/freetype/ftstroke.h: Updated. 2011-06-30 İsmail Dönmez <ismail@namtrac.org> * builds/toplevel.mk: We use git, not CVS, thus skip `.gitignore'. 2011-06-29 Werner Lemberg <wl@gnu.org> [bdf] Fix Savannah bug #33663. * src/bdf/bdflib.c (_bdf_parse_glyphs): Handle negative values for ENCODING correctly. * docs/CHANGES: Document it. 2011-06-24 Werner Lemberg <wl@gnu.org> * Version 2.4.5 released. ========================= Tag sources with `VER-2-4-5'. * docs/CHANGES: Updated. * docs/VERSION.DLL: Update documentation and bump version number to 2.4.5 * README, Jamfile (RefDoc), builds/win32/vc2005/freetype.vcproj, builds/win32/vc2005/index.html, builds/win32/vc2008/freetype.vcproj, builds/win32/vc2008/index.html, builds/win32/vc2010/freetype.vcxproj, builds/win32/vc2010/index.html, builds/win32/visualc/freetype.dsp, builds/win32/visualc/freetype.vcproj, builds/win32/visualc/index.html, builds/win32/visualce/freetype.dsp, builds/win32/visualce/freetype.vcproj, builds/win32/visualce/index.html, builds/wince/vc2005-ce/freetype.vcproj, builds/wince/vc2005-ce/index.html, builds/wince/vc2008-ce/freetype.vcproj, builds/wince/vc2008-ce/index.html: s/2.4.4/2.4.5/, s/244/245/. * include/freetype/freetype.h (FREETYPE_PATCH): Set to 5. * builds/unix/configure.raw (version_info): Set to 13:0:7. 2011-06-20 Werner Lemberg <wl@gnu.org> * src/autofit/aflatin.c (af_latin_metrics_scale_dim): Fix change from 2011-05-04. 2011-06-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> [gxvalid] make the `prop' validation tracing verbose. * src/gxvalid/gxvprop.c: Add tracing messages for errors. 2011-06-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> [autogen.sh] Reflect environment variable LIBTOOLIZE. 2011-06-18 Werner Lemberg <wl@gnu.org> Update license documentation. * docs/GPL.TXT: Renamed to... * docs/GPLv2.TXT: This. * docs/LICENSE.TXT: Updated. 2011-06-14 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> Fix g++4.6 compiler warnings in module drivers.

At the same time, try to provide sane values which hopefully allow useful continuation. Exception to this is CALL and LOOPCALL – due to possible stack corruption it is necessary to bail out. 2011-01-31 Werner Lemberg <wl@gnu.org> [truetype] Improve handling of stack underflow. * src/truetype/ttinterp.c (TT_RunIns, Ins_FLIPPT, Ins_DELTAP, Ins_DELTAC): Exit with error only if `pedantic_hinting' is set.

Thanks to Greg Hitchcock who explained the issue. * src/truetype/ttinterp.c (Ins_MIRP): Replace a `>=' operator with `>' since the description in the specification is incorrect. This fixes, for example, glyph `two' in font `Helvetica Neue LT Com 65 medium' at 15ppem. 2011-01-15 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> Fix ARM assembly code in include/freetype/config/ftconfig.h. * include/freetype/config/ftconfig.h (FT_MulFix_arm): Copy the maintained code from builds/unix/ftconfig.in. Old GNU binutils could not accept the reduced syntax `orr %0, %2, lsl #16'. Un-omitted syntax like RVCT, `orr %0, %0, %2, lsl #16' is better. Reported by Johnson Y. Yan. The bug report by Qt developers is considered too. https://bugreports.qt.io/browse/QTBUG-6521 2011-01-15 Werner Lemberg <wl@gnu.org> [raster] Make bbox handling the same as with Microsoft's rasterizer. Right before B/W rasterizing, the bbox gets simply rounded to integers. This fixes, for example, glyph `three' in font `Helvetica Neue LT Com 65 Medium' at 11ppem. Thanks to Greg Hitchcock who explained this behaviour. * src/raster/ftrend1.c (ft_raster1_render): Implement it. 2011-01-15 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> Copy -mcpu=* & -march=* options from CFLAGS to LDFLAGS. * builds/unix/configure.raw: Consider recent gcc-standard flags to specify architecture in CFLAGS & LDFLAGS harmonization.

This catches a rendering problem with glyph `x' from Tahoma at 10ppem. It seems that the increase of the precision in the change from 2009-06-11 makes a larger jitter value unnecessary. * src/raster/ftraster.c (Set_High_Precision): Implement it. 2011-01-13 Werner Lemberg <wl@gnu.org> [raster] Handle drop-outs at glyph borders according to Microsoft. If a drop-out rule would switch on a pixel outside of the glyph's bounding box, use the right (or top) pixel instead. This is an undocumented feature, but some fonts like `Helvetica Neue LT Com 65 Medium' heavily rely on it. Thanks to Greg Hitchcock who explained this behaviour. * src/raster/ftraster.c (Vertical_Sweep_Drop, Horizontal_Sweep_Drop): Implement it. 2011-01-09 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> [cache] Fix Savannah bug #31923, patch drafted by Harsha. When a node comparator changes the cached nodes during the search of a node matching with queried properties, the pointers obtained before the function should be updated to prevent the dereference to freed or reallocated nodes. To minimize the rescan of the linked list, the update is executed when the comparator notifies the change of cached nodes. This change depends previous change: 38b272ffbbdaae276d636aec4ef84af407d16181 * src/cache/ftccache.h (FTC_CACHE_LOOKUP_CMP): Rescan the top node if the cached nodes are changed. * src/cache/ftccache.c (FTC_Cache_Lookup): Ditto. 2011-01-09 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> [cache] Notice if a cache query induced the node list change. Some node comparators (comparing the cache node contents and the properties specified by the query) can flush the cache node to prevent the cache inflation. The change may invalidate the pointers to the node obtained before the node comparison, so it should be noticed to the caller. The problem caused by the cache node changing is reported by Harsha, see Savannah bug #31923. * src/cache/ftccache.h (FTC_Node_CompareFunc): Add new argument `FT_Bool* list_changed' to indicate the change of the cached nodes to the caller. (FTC_CACHE_LOOKUP_CMP): Watch the change of the cached nodes by `_list_changed'. (FTC_CACHE_TRYLOOP_END): Take new macro argument `_list_changed' and update it when `FTC_Manager_FlushN' flushes any nodes. * src/cache/ftccback.h (ftc_snode_compare): Updated to fit with new FTC_Node_CompareFunc type. (ftc_gnode_compare): Ditto. * src/cache/ftcbasic.c: Include FT_INTERNAL_OBJECTS_H to use TRUE/FALSE macros. (ftc_basic_gnode_compare_faceid): New argument `FT_Bool* list_changed' to indicate the change of the cache nodes (anyway, it is always FALSE). * src/cache/ftccmap.c: Include FT_INTERNAL_OBJECTS_H to use TRUE/FALSE macros. (ftc_cmap_node_compare): New argument `FT_Bool* list_changed' to indicate the change of the cache nodes (anyway, it is always FALSE). (ftc_cmap_node_remove_faceid): Ditto. * src/cache/ftccache.c (FTC_Cache_NewNode): Pass a NULL pointer to `FTC_CACHE_TRYLOOP_END', because the result is not needed. (FTC_Cache_Lookup): Watch the change of the cache nodes by `list_changed'. (FTC_Cache_RemoveFaceID): Ditto. * src/cache/ftcglyph.c: Include FT_INTERNAL_OBJECTS_H to use TRUE/FALSE macros. (ftc_gnode_compare): New argument `FT_Bool* list_changed' to indicate the change of the cache nodes (anyway, it is always FALSE). (FTC_GNode_Compare): New argument `FT_Bool* list_changed' to be passed to `ftc_gnode_compare'. * src/cache/ftcglyph.h (FTC_GNode_Compare): Ditto. * src/cache/ftcsbits.c (ftc_snode_compare): New argument `FT_Bool* list_changed' to indicate the change of the cache nodes, anyway. It is updated by `FTC_CACHE_TRYLOOP'. (FTC_SNode_Compare): New argument `FT_Bool* list_changed' to be passed to `ftc_snode_compare'. * src/cache/ftcsbits.h (FTC_SNode_Compare): Ditto. 2011-01-09 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> [cache] Fit `FTC_GNode_Compare' to `FTC_Node_CompareFunc'. * src/cache/ftcglyph.h (FTC_GNode_Compare): Add the 3rd argument `FTC_Cache cache' to fit FTC_Node_CompareFunc prototype. * src/cache/ftcglyph.c (FTC_GNode_Compare): Ditto. Anyway, `cache' is not used by its child `ftc_gnode_compare'. 2011-01-09 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> [cache] Deduplicate the code to get the top node by a hash. There are several duplicated code fragments getting the top node from a cache by a given hash, like: idx = hash & cache->mask; if ( idx < cache->p ) idx = hash & ( cache->mask * 2 + 1 ); pnode = cache->buckets + idx; To remove duplication, a cpp-macro to do same work `FTC_NODE__TOP_FOR_HASH' is introduced. For non-inlined configuration, non-`ftc_get_top_node_for_hash' is also introduced. * src/cache/ftccache.h (FTC_NODE__TOP_FOR_HASH): Declare and implement inlined version. (FTC_CACHE_LOOKUP_CMP): Use `FTC_NODE__TOP_FOR_HASH'. * src/cache/ftccache.c (ftc_get_top_node_for_hash): Non-inlined version. (ftc_node_hash_unlink): Use `FTC_NODE__TOP_FOR_HASH'. (ftc_node_hash_link): Ditto. (FTC_Cache_Lookup): Ditto. 2011-01-09 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> [cache] inline-specific functions are conditionalized. * src/cache/ftcglyph.c (FTC_GNode_Compare): Conditionalized for inlined configuration. This function is a thin wrapper of `ftc_gnode_compare' for inlined `FTC_CACHE_LOOKUP_CMP' (see `nodecmp' argument). Under non-inlined configuration, `ftc_gnode_compare' is invoked by `FTC_Cache_Lookup', via `FTC_Cache->clazz.node_compare'. * src/cache/ftcglyph.h (FTC_GNode_Compare): Ditto. * src/cache/ftcsbits.c (FTC_SNode_Compare): Ditto, for `ftc_snode_compare'. * src/cache/ftcsbits.h (FTC_SNode_Compare): Ditto. 2011-01-09 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> [cache] Correct a type mismatch under non-inlined config. * src/cache/ftcglyph.h (FTC_GCACHE_LOOKUP_CMP): `FTC_GCache_Lookup' takes the node via a pointer `FTC_Node', differently from cpp-macro `FTC_CACHE_LOOKUP_CMP'. 2011-01-06 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> Update Jamfile to include Bzip2 support. Jamfile: Include src/bzip2 to project. Comments for lzw, gzip, bzip2 are changed to clarify that they are for compressed PCF fonts, not others. (e.g. compressed BDF fonts are not supported yet) 2011-01-05 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> Update Symbian project files to include Bzip2 support. Currently, it provides `FT_Stream_OpenBzip2' that returns unimplemented error always, to prevent unresolved symbol error for the applications designed for Unix systems. * builds/symbian/bld.inf: Include ftbzip2.h. * builds/symbian/freetype.mmp: Include ftbzip2.c. 2011-01-05 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> Update classic MacOS makefiles to include Bzip2 support. Currently, it provides `FT_Stream_OpenBzip2' that returns unimplemented error always, to prevent unresolved symbol error for the applications designed for Unix systems. * builds/mac/FreeType.m68k_cfm.make.txt: Include ftbzip2.c.o. * builds/mac/FreeType.m68k_far.make.txt: Ditto. * builds/mac/FreeType.ppc_carbon.make.txt: Include ftbzip2.c.x. * builds/mac/FreeType.ppc_classic.make.txt: Ditto. 2011-01-05 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> Update Amiga makefiles to include Bzip2 support.

SYSTEM_ZLIB is used to switch the builtin zlib source or system zlib source out of FreeType2. But ftbzip2 module has no builtin bzip2 library and always requires system bzip2 library. Thus SYSTEM_BZ2LIB is always yes, it is not used. 2011-01-03 Werner Lemberg <wl@gnu.org> /rules.mk: Handle `pic.c' files. 2010-12-31 Werner Lemberg <wl@gnu.org> * src/cff/cfftypes.h (CFF_MAX_CID_FONTS): Increase to 64.

(PCF_Face_Init): Handle bzip2 compressed files. * docs/formats.txt, modules.cfg: Updated. 2010-12-25 Harsha <mm.harsha@gmail.com> Apply Savannah patch #7422. If we encounter a space in a string then the sbit buffer is NULL, height and width are 0s. So the check in ftc_snode_compare will always pass for spaces (comparison with 255). Here the comments above the condition are proper but the implementation is not. When we create an snode I think it is the proper way to initialize the width to 255 and then put a check for being equal to 255 in snode compare function. * src/cache/ftcsbits.c (FTC_SNode_New): Initialize sbit widths with value 255. (ftc_snode_compare): Fix condition. 2010-12-13 Werner Lemberg <wl@gnu.org> Fix parameter handling of `FT_Set_Renderer'.

Problem reported by Tom Bishop <wenlin@wenlin.com>; see thread starting with https://lists.gnu.org/archive/html/freetype/2010-10/msg00049.html * src/raster/ftraster.c (Line_Up): Replace FMulDiv with SMulDiv since the involved multiplication exceeds 32 bits. 2010-10-25 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> Revert a change of `_idx' type in `FTC_CACHE_LOOKUP_CMP'. * src/cache/ftccache.h (FTC_CACHE_LOOKUP_CMP): Revert the type of `_idx' from FT_PtrDist (by previous change) to original FT_UFast, to match with FT_CacheRec. 2010-10-24 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> [cache] Change the hash types to FT_PtrDist. On LLP64 platforms (e.g. Win64), FT_ULong (32-bit) variables are inappropriate to calculate hash values from the memory address (64-bit). The hash variables are extended from FT_ULong to FT_PtrDist and new hashing macro functions are introduced. The hash values on 16-bit memory platforms are changed, but ILP32 and LP64 are not changed. The hash value in the cache subsystem is not reverted to the memory address, so using signed type FT_PtrDist is safe. * src/cache/ftccache.h (_FTC_FACE_ID_HASH): New hash function to replace `FTC_FACE_ID_HASH' for portability. * src/cache/ftcmanag.h (FTC_SCALER_HASH): Replace `FTC_FACE_ID_HASH' by `_FTC_FACE_ID_HASH'. * src/cache/ftccmap.c (FTC_CMAP_HASH): Ditto. * src/cache/ftccache.h (FTC_NodeRec): The type of the member `hash' is changed from FT_UInt32 to FT_PtrDist. * src/cache/ftccache.h (FTC_Cache_Lookup): The type of the argument `hash' is changed from FT_UInt32 to FT_PtrDist.

On LLP64 platforms (e.g. Win64), unsigned long (32-bit) cannot cover the memory address (64-bit). `FT_MEM_VAL' is used for hashing only and not dereferred, so using signed type FT_PtrDist is safe. * src/base/ftdbgmem.c (FT_MEM_VAL): Change the type of the return value from FT_ULong to FT_PtrDist. (ft_mem_table_resize): The type of hash is changed to FT_PtrDist. (ft_mem_table_get_nodep): Ditto. 2010-10-24 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> Replace "%lx" for memory address by "%p", LLP64 platforms. On LLP64 platforms (e.g. Win64), long (32-bit) cannot cover the memory address (64-bit). Also the casts from the pointer type to long int should be removed to preserve the address correctly. * src/raster/ftraster.c (New_Profile): Replace "%lx" by "%p".

When a resource fork access rule by Darwin VFS could open the resource fork but no font is found in it, the rest of rules by Darwin VFS are skipped. It reduces the warnings of the deprecated resource fork access method by recent Darwin kernel. Fix MacPorts ticket #18859: https://trac.macports.org/ticket/18859 * src/base/ftobjs.c (load_face_in_embedded_rfork): When `FT_Stream_New' returns FT_Err_Cannot_Open_Stream, it means that the file is possible to be `fopen'-ed but zero-sized. Also there is a case that the resource fork is not zero-sized, but no supported font exists in it. If a rule by Darwin VFS falls into such cases, there is no need to try other Darwin VFS rules anymore. Such cases are marked by vfs_rfork_has_no_font. If it is TRUE, the Darwin VFS rules are skipped. 2010-10-13 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> [raccess] Grouping resource access rules based on Darwin VFS. MacOS X/Darwin kernel supports a few tricky methods to access a resource fork via ANSI C or POSIX interface. Current resource fork accessor tries all possible methods to support all kernels. But if a method could open a resource fork but no font is found, there is no need to try other methods older than tested method. To determine whether the rule index is for Darwin VFS, a local function `ftrfork.c::raccess_rule_by_darwin_vfs' is introduced. To use this function in ftobjs.c etc but it should be inlined, it is exposed by ftbase.h. * src/base/ftrfork.c (FT_RFork_Rule): New enum type to identify the rules to access the resource fork. (raccess_guess_rec): New structure to bind the rule function and rule enum type. (FT_Raccess_Guess): The list of the rule functions is replaced by (raccess_guess_table): This. This is exposed to be used by other intra module functions. (raccess_rule_by_darwin_vfs): A function to return a boolean if the rule specified by the rule index is based on Darwin VFS. 2010-10-13 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> Prevent to open a FT_Stream for zero-sized file on non-Unix. builds/unix/ftsystem.c prevents to open an useless stream from zero-sized file and returns FT_Err_Cannot_Open_Stream, but the stream drivers for ANSI C, Amiga and VMS return useless streams.

Information provided by Alan Coopersmith <alan.coopersmith@oracle.com>. 2010-05-10 Ken Sharp <ken.sharp@artifex.com> [psaux] Fix Savannah bug #29846. Previously we discovered fonts which used `setcurrentpoint' to set the initial point of a contour to 0,0. This caused FreeType to raise an error, because the `setcurrentpoint' operator is only supposed to be used with the results from an OtherSubr subroutine. This was fixed by simply ignoring the error and carrying on. Now we have found a font which uses setcurrentpoint to actually establish a non-zero point for a contour during the course of a glyph program. FWIW, these files may be produced by an application called `Intaglio' on the Mac, when converting TrueType fonts to Type 1. The fix allows the new invalid behaviour, the old invalid behaviour and real proper usage of the operator to work the same way as Adobe interpreters apparently do. * src/psaux/t1decode.c (t1_decoder_parse_charstrings): Make `setcurrentpoint' use the top two elements of the stack to establish unconditionally the current x and y coordinates. Make the `flex' subroutine handling (OtherSubr 0) put the current x,y coordinates onto the stack, instead of two dummy uninitialised values. 2010-04-14 Ken Sharp <ken.sharp@artifex.com> [psaux] Fix Savannah bug #29444. * src/psaux/psobjs.c (t1_builder_start_point): Accept (invalid) `lineto' immediately after `hsbw', in accordance with Acrobat, GS, and others. 2010-04-14 Michał Cichoń <thedmd@artifexmundi.com> [psaux] Fix Savannah bug #27999. * src/cache/ftcmanag.c (FTC_Manager_RemoveFaceID): Only remove selected entry, not all. 2010-04-06 Jonathan Kew <jfkthame@gmail.com> [truetype] Add overflow check to `fvar' table. * src/truetype/ttgxvar.c (TT_Get_MM_Var): Check axis and instance count. 2010-04-05 Ken Sharp <ken.sharp@artifex.com> [raster] Fix Savannah bug #29335. * src/raster/ftraster.c (Line_Up): Use slow multiplication to prevent overflow.

2014-12-30 Werner Lemberg <wl@gnu.org> * Version 2.5.5 released. ========================= Tag sources with `VER-2-5-5'. * docs/VERSION.DLL: Update documentation and bump version number to 2.5.5. * README, Jamfile (RefDoc), builds/windows/vc2005/freetype.vcproj, builds/windows/vc2005/index.html, builds/windows/vc2008/freetype.vcproj, builds/windows/vc2008/index.html, builds/windows/vc2010/freetype.vcxproj, builds/windows/vc2010/index.html, builds/windows/visualc/freetype.dsp, builds/windows/visualc/freetype.vcproj, builds/windows/visualc/index.html, builds/windows/visualce/freetype.dsp, builds/windows/visualce/freetype.vcproj, builds/windows/visualce/index.html, builds/wince/vc2005-ce/freetype.vcproj, builds/wince/vc2005-ce/index.html, builds/wince/vc2008-ce/freetype.vcproj, builds/wince/vc2008-ce/index.html: s/2.5.4/2.5.5/, s/254/255/. * include/freetype/freetype.h (FREETYPE_PATCH): Set to 5. * builds/unix/configure.raw (version_info): Set to 17:4:11. * CMakeLists.txt (VERSION_PATCH): Set to 5. * docs/CHANGES: Updated. * builds/toplevel.mk (dist): Fix typos. 2014-12-24 Alexei Podtelezhnikov <apodtele@gmail.com> [base] Formatting and nanooptimizations. * src/base/ftcalc.c, * src/base/fttrigon.c: Revise sign restoration. 2014-12-13 Werner Lemberg <wl@gnu.org> * src/pcf/pcfread.c (pcf_read_TOC): Improve fix from 2014-12-08. 2014-12-11 Werner Lemberg <wl@gnu.org> * builds/toplevel.mk (dist): Use older POSIX standard for `tar'. Apparently, BSD tar isn't capable yet of handling POSIX-1.2001 (contrary to GNU tar), so force the POSIX-1.1988 format. Problem reported by Stephen Fisher <sfisher@SDF.ORG>. 2014-12-11 Werner Lemberg <wl@gnu.org> * src/type42/t42parse.c (t42_parse_sfnts): Reject invalid TTF size. 2014-12-11 Werner Lemberg <wl@gnu.org> * src/base/ftobjs.c (FT_Get_Glyph_Name): Fix off-by-one check. Problem reported by Dennis Felsing <dennis@felsin9.de>. 2014-12-11 Werner Lemberg <wl@gnu.org> * src/type42/t42parse.c (t42_parse_sfnts): Check `string_size'. Problem reported by Dennis Felsing <dennis@felsin9.de>. 2014-12-09 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> [gxvalid] Fix a naming convention conflicting with ftvalid. See previous changeset for otvalid. * src/gxvalid/{gxvcommn.h, gxvmort.h, gxvmorx.h}: Replace `valid' by `gxvalid'. * src/gxvalid/{gxvbsln.c, gxvcommn.c, gxvfeat.c, gxvjust.c, gxvkern.c, gxvlcar.c, gxvmort.c, gxvmort0.c, gxvmort1.c, gxvmort2.c, gxvmort4.c, gxvmort5.c, gxvmorx.c, gxvmorx0.c, gxvmorx1.c, gxvmorx2.c, gxvmorx4.c, gxvmorx5.c, gxvopbd.c, gxvprop.c, gxvtrak.c}: Replace `valid' by `gxvalid' if it is typed as GXV_Validator. 2014-12-09 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> [otvalid] Fix a naming convention conflicting with ftvalid. Some prototypes in ftvalid.h use `valid' for the variables typed as FT_Validator. Their implementations in src/base/ ftobjs.c and utilizations in src/sfnt/ttcmap.c do similar. Some macros in otvcommn.h assume the exist of the variable `valid' typed as OTV_Validator in the caller. Mixing these two conventions cause invalid pointer conversion and unexpected SEGV in longjmp. To prevent it, all variables typed as OTV_Validator are renamed to `otvalid'. * src/otvalid/otvcommn.h: Replace `valid' by `otvalid'. * src/otvalid/{otvcommn.c, otvbase.c, otvgdef.c, otvgpos.c, otvgsub.c, otvjstf.c, otvmath.c}: Replace `valid' by `otvalid' if it is typed as OTV_Validator. 2014-12-09 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> [ftvalid] Introduce FT_THROW() in FT_INVALID_XXX macros. Original patch is designed by Werner Lemberg. Extra part for otvalid and gxvalid are added by suzuki toshiya, see discussion: https://lists.nongnu.org/archive/html/freetype-devel/2014-12/msg00002.html https://lists.nongnu.org/archive/html/freetype-devel/2014-12/msg00007.html * include/internal/ftvalid.h: Introduce FT_THROW() in FT_INVALID_(). * src/gxvalid/gxvcommn.h: Ditto. * src/otvalid/otvcommn.h: Ditto. 2014-12-08 Werner Lemberg <wl@gnu.org> [pcf] Fix Savannah bug #43774. Work around `features' of X11's `pcfWriteFont' and `pcfReadFont' functions. Since the PCF format doesn't have an official specification, we have to exactly follow these functions' behaviour. The problem was unveiled with a patch from 2014-11-06, fixing issue #43547. * src/pcf/pcfread.c (pcf_read_TOC): Don't check table size for last element. Instead, assign real size. 2014-12-07 Werner Lemberg <wl@gnu.org> Work around a bug in Borland's C++ compiler. See http://qc.embarcadero.com/wc/qcmain.aspx?d=118998 for Borland's bug tracker entry. Reported by Yuliana Zigangirova <zigangirova@inbox.ru>, https://lists.gnu.org/archive/html/freetype-devel/2014-04/msg00001.html. * include/internal/ftvalid.h (FT_ValidatorRec), src/smooth/ftgrays.c (gray_TWorker_): Move `ft_jmp_buf' field to be the first element. 2014-12-07 Werner Lemberg <wl@gnu.org> /: Decorate hex constants with `U' and `L' where appropriate. 2014-12-07 Werner Lemberg <wl@gnu.org> [truetype] Prevent memory leak for buggy fonts. * src/truetype/ttobjs.c (tt_size_done): Unconditionally call `tt_size_done_bytecode'. 2014-12-06 Werner Lemberg <wl@gnu.org> * Version 2.5.4 released. ========================= Tag sources with `VER-2-5-4'. * docs/VERSION.DLL: Update documentation and bump version number to 2.5.4. * README, Jamfile (RefDoc), builds/windows/vc2005/freetype.vcproj, builds/windows/vc2005/index.html, builds/windows/vc2008/freetype.vcproj, builds/windows/vc2008/index.html, builds/windows/vc2010/freetype.vcxproj, builds/windows/vc2010/index.html, builds/windows/visualc/freetype.dsp, builds/windows/visualc/freetype.vcproj, builds/windows/visualc/index.html, builds/windows/visualce/freetype.dsp, builds/windows/visualce/freetype.vcproj, builds/windows/visualce/index.html, builds/wince/vc2005-ce/freetype.vcproj, builds/wince/vc2005-ce/index.html, builds/wince/vc2008-ce/freetype.vcproj, builds/wince/vc2008-ce/index.html: s/2.5.3/2.5.4/, s/253/254/. * include/freetype/freetype.h (FREETYPE_PATCH): Set to 4. * builds/unix/configure.raw (version_info): Set to 17:3:11. * CMakeLists.txt (VERSION_PATCH): Set to 4. * docs/CHANGES: Updated. 2014-12-04 Werner Lemberg <wl@gnu.org> docs/CHANGES: Updated, formatted. 2014-12-04 Dave Arnold <darnold@adobe.com> [cff] Modify an FT_ASSERT. * src/cff/cf2hints.c (cf2_hintmap_map): After the fix for Savannah bug #43661, the test font `...aspartam.otf' still triggers an FT_ASSERT. Since hintmap still works with count==0, ... (cf2_glyphpath_lineTo, cf2_glyphpath_curveTo): ... add that term to suppress the assert. 2014-12-04 Dave Arnold <darnold@adobe.com> [cff] Fix Savannah bug #43661. * src/cff/cf2intrp.c (cf2_interpT2CharString) <cf2_cmdHSTEM, cf2_cmdVSTEM, cf2_cmdHINTMASK>: Don't append to stem arrays after hintmask is constructed. * src/cff/cf2hints.c (cf2_hintmap_build): Add defensive code to avoid reading past end of hintmask. 2014-12-03 Werner Lemberg <wl@gnu.org> docs/CHANGES: Updated. 2014-12-03 Werner Lemberg <wl@gnu.org> [autofit] Better fix for conversion specifiers in debug messages. Using `%ld' for pointer differences causes warnings on 32bit platforms. The correct type would be (the relatively new) `%td', however, this is missing on some important platforms. This patch improves the change from 2014-11-28. * src/autofit/afhints.c (AF_INDEX_NUM): Use `int' typecast. Our pointer differences are always sufficiently small. (af_glyph_hints_dump_points, af_glyph_hints_dump_segments, af_glyph_hints_dump_edge): Revert to `%d' and use `AF_INDEX_NUM'. 2014-12-03 Werner Lemberg <wl@gnu.org> FT_Sfnt_Tag: s/ft_sfnt_xxx/FT_SFNT_XXX/ for orthogonality. All public FreeType enumeration and flag values are uppercase... * include/tttables.h (FT_Sfnt_Tag): Implement it. For backward compatibility, retain the old values as macros. * src/base/ftfstype.c (FT_Get_FSType_Flags), src/sfnt/sfdriver.c (get_sfnt_table): Updated. 2014-12-02 Werner Lemberg <wl@gnu.org> * include/: Improve structure of documentation. . Add and update many `<Order>' tags. . Apply various documentation fixes. . Remove details to deprecated (or never implemented) data. 2014-12-02 Werner Lemberg <wl@gnu.org> [docmaker] Always handle `<Order>' section elements. Previously, those elements were handled only for sections present in a `<Sections>' chapter element. src/tools/docmaker/content.py (ContentProcessor::finish): Implement it. 2014-12-02 Werner Lemberg <wl@gnu.org> [docmaker] Properly handle empty rows in Synopsis. * src/tools/docmaker/tohtml.py (HtmlFormatter::section_enter): Emit ` ' for empty fields. 2014-12-02 Werner Lemberg <wl@gnu.org> [docmaker] Thinko. * src/tools/docmaker/content.py (DocBlock::get_markup_words_all): Emit `/empty/' string for first element also. 2014-12-02 Werner Lemberg <wl@gnu.org> [docmaker] Honour empty lines in `<Order>' section element. This greatly improves the readability of the `Synopsis' links. * src/tools/docmaker/content.py (DocBlock::get_markup_words_all): Insert string `/empty/' between items. * src/tools/docmaker/formatter.py (Formatter::section_dump): Make it robust against nonexistent keys. * src/tools/docmaker/tohtml.py (HtmlFormatter::section_enter): Emit empty <td> elements for `/empty/'. 2014-12-02 Werner Lemberg <wl@gnu.org> [docmaker] Ensure Python 3 compatibility. * src/tools/docmaker/content.py (ContentProcessor::set_section, ContentProcessor::finish): Replace `has_key' function with `in' keyword. * src/tools/docmaker/formatter.py (Formatter::__init__): Replace sorting function with a key generator. (Formatter::add_identifier): Replace `has_key' function with `in' keyword. * src/tools/docmaker/tohtml.py (HtmlFormatter::html_source_quote): Replace `has_key' function with `in' keyword. (HtmlFormatter::index_exit, HtmlFormatter::section_enter): Use integer division. s/<>/>/. * src/tools/docmaker/utils.py: Import `itertools'. (index_sort): Replaced by... (index_key): ... this new key generator (doing exactly the same). 2014-11-29 Werner Lemberg <wl@gnu.org> [docmaker] Don't output a block multiple times. This bug was hidden by not processing all lines of `<Order>' blocks. * src/tools/docmaker/formatter.py (Formatter::section_dump): Filter out field names. 2014-11-29 Werner Lemberg <wl@gnu.org> [docmaker] Use field values as HTML link targets where possible. * src/tools/docmaker/tohtml.py (HtmlFormatter::make_block_url): Accept second, optional argument to specify a name. (HtmlFormatter::html_source_quote): Link to field ID if possible. (HtmlFormatter::print_html_field_list): Emit `id' attribute. 2014-11-29 Werner Lemberg <wl@gnu.org> [docmaker] Allow empty lines in `<Order>' blocks. Before this patch, the suggested order of entries stopped at the first empty line. Obviously, nobody noticed that this problem caused a much reduced set of links in the `Synopsis' sections; in particular, the `<Order>' blocks contain a lot of entries that wouldn't be listed otherwise... * src/tools/docmaker/content.py (DocBlock::get_markup_words_all): New function to iterate over all items. (DocSection::process): Use it. 2014-11-29 Werner Lemberg <wl@gnu.org> * src/tools/docmaker/sources.py (column) [Format 2]: Fix regexp. After the single asterisk there must be no other immediately following asterisk. 2014-11-29 Werner Lemberg <wl@gnu.org> * src/tools/docmaker/tohtml.py: Improve CSS for vertical spacing. 2014-11-29 Werner Lemberg <wl@gnu.org> [docmaker] Improve HTML code for table of contents. * src/tools/docmaker/tohtml.py: Introduce a new table class `toc', together with proper CSS. 2014-11-29 Werner Lemberg <wl@gnu.org> [docmaker] Provide higher-level markup and simplify HTML. * src/tools/docmaker/tohtml.py: Instead of using extraneous `<div>' elements, use CSS descendants (of class `section') to format the data. Also remove redundant <p> and <br> elements, replacing them with proper CSS. Globally reduce page width to 75%. (block_header): Rename <div> class to `section'. 2014-11-29 Werner Lemberg <wl@gnu.org> [docmaker] Add `top' links after blocks. * src/tools/docmaker/tohtml.py (block_footer_middle): Implement it. 2014-11-29 Werner Lemberg <wl@gnu.org> * src/tools/docmaker/tohtml.py: Improve CSS for fields. Make fields align horizontally relative to full line width. 2014-11-29 Werner Lemberg <wl@gnu.org> * src/tools/docmaker/tohtml.py: Fix index and TOC templates. This thinko was introduced 2014-11-27. 2014-11-28 Werner Lemberg <wl@gnu.org> [docmaker] Format field lists with CSS. This also simplifies the inserted HTML code. * src/tools/docmaker/tohtml.py (HtmlFormatter::print_html_field_list): Do it. 2014-11-28 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> Fix compiler warning to the comparison between signed and unsigned variable. * src/pfr/pfrsbit.c (pfr_slot_load_bitmap): Fix the comparison between `ypos + ysize' and FT_INT_{MAX,MIN}. 2014-11-28 Werner Lemberg <wl@gnu.org> [docmaker] Replace empty `<td>' with CSS. * src/tools/docmaker/tohtml.py (HtmlFormatter::section_enter): Do it. 2014-11-28 Werner Lemberg <wl@gnu.org> [docmaker] Replace some `<table>' tags with `<h4>' and `<div>'. * src/tools/docmaker/tohtml.py (marker_): Use `<h4>'. (source_): Use `<div>'. (HtmlFormatter::block_enter): s/<h4>/<h3>/. 2014-11-28 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> Fix compiler warning to conversion specifiers in debug messages. * src/autofit/afhints.c (af_glyph_hints_dump_points): Add length modifier to dump long integers. (af_glyph_hints_dump_segments, af_glyph_hints_dump_edges): Ditto. 2014-11-27 Werner Lemberg <wl@gnu.org> * src/tools/docmaker/tohtml.py: Use more CSS for index. 2014-11-27 Werner Lemberg <wl@gnu.org> [docmaker] Replace `name' attribute of `<a>' with `id'. * src/tools/docmaker/tohtml.py (HtmlFormatter::block_enter): Do it. 2014-11-27 Werner Lemberg <wl@gnu.org> * src/tools/docmaker/tohtml.py: Remove remaining `width' attributes. For `Index' and `TOC' links, we now simply use the `text-align' CSS property of `<td>' to enforce flush-left and flush-right, eliminating the hack with an empty, full-width `<td>' element inbetween. The change also enforces the same (smaller) size for all index and TOC links. 2014-11-27 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * src/cff/cf2font.c: Include `ftcalc.h' to use FT_MSB(), cf2font.c could not find it under `make multi' build. 2014-11-27 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * src/smooth/ftsmooth.c (ft_smooth_render_generic): Remove unrequired negative value check for `width' and `height'. 2014-11-27 Werner Lemberg <wl@gnu.org> * src/tools/docmaker/tohtml.py: More HTML table refactoring. Replace some `<table>' tags with `<div>' to simplify structure. Move `bgcolor' attribute to CSS. Replace most `width' attributes with CSS. The remaining instances (providing a similar effect as LaTeX's `\hfill' command) are removed in a later patch. 2014-11-27 Werner Lemberg <wl@gnu.org> * src/tools/docmaker/tohtml.py: Replace <font> with CSS. 2014-11-27 Werner Lemberg <wl@gnu.org> * src/tools/docmaker/tohtml.py: Center <table> with CSS. 2014-11-27 Werner Lemberg <wl@gnu.org> * src/tools/docmaker/tohtml.py: Replace `<center>' with `<div>'. 2014-11-27 Werner Lemberg <wl@gnu.org> * src/tools/docmaker/tohtml.py: Remove redundant `<center>' tags. This starts a series of commits into the direction of generating valid HTML 5 code, especially using much more CSS. 2014-11-27 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> Prevent too negative values (< FT_INT_MIN) in bitmap metrics, suggested by Alexei. * src/pfr/pfrsbit.c (pfr_slot_load_bitmap): Prevent too negative values in `xpos' and `ypos + ysize'. * src/smooth/ftsmooth.c (ft_smooth_render_generic): Prevent too negative values in `x_left' and `y_top'. Either negative values in `width' and `height' are checked. 2014-11-27 Werner Lemberg <wl@gnu.org> [docmaker] Produce better HTML code. * src/tools/docmaker/tohtml.py: Always use double quotes for attribute values. (source_footer): Close `td' and `tr' groups. 2014-11-27 Werner Lemberg <wl@gnu.org> Use better way to disable creation of .pyc files for `make refdoc'. Python 2.6 was released in 2008... * builds/freetype.mk (refdoc): Use python's `-B' option. * builds/detect.mk (std_setup, dos_setup): Mention required python version for `refdoc' target. 2014-11-27 Werner Lemberg <wl@gnu.org> * src/tools/docmaker/sources.py (re_bold, re_italic): Use non-grouping parentheses. * src/tools/docmaker/tohtml.py (HtmlFormatter::make_html_word): Updated. 2014-11-27 Werner Lemberg <wl@gnu.org> * src/base/ftobjs.c (FT_Get_Glyph_Name): Fix compiler warning. Introduced in previous change. Reported by Alexei. 2014-11-26 Werner Lemberg <wl@gnu.org> * src/: Add checks for parameters of API functions where missing. `API functions' are functions tagged with `FT_EXPORT_DEF'. Besides trivial fixes, the following changes are included, too. src/base/ftbdf.c (FT_Get_BDF_Charset_ID, FT_Get_BDF_Property): Set error code if no service is available. * src/base/ftinit.c (FT_Done_FreeType): Change return value for invalid `library' parameter to `Invalid_Library_Handle'. * src/base/ftobjs.c (FT_New_Size): Change return value for invalid `asize' parameter to `Invalid_Argument'. * src/base/ftoutln.c (FT_Outline_Copy): Change return value for invalid `source' and `target' parameters to `Invalid_Outline'. (FT_Outline_Done_Internal): Change return value for invalid `outline' parameter to `Invalid_Outline'. 2014-11-26 Werner Lemberg <wl@gnu.org> * src/cache/ftcbasic.c: Use single calls to `FT_TRACE'. 2014-11-26 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * src/base/ftobjs.c (Mac_Read_POST_Resource): Additional overflow check in the summation of POST fragment lengths, suggested by Mateusz Jurczyk <mjurczyk@google.com>. 2014-11-26 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * src/base/ftobjs.c (Mac_Read_POST_Resource): Insert comments and fold too long tracing messages. 2014-11-26 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> Fix Savannah bug #43540. * src/base/ftmac.c (parse_fond): Prevent a buffer overrun caused by a font including too many (> 63) strings to store names[] table. 2014-11-26 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * src/base/ftobjs.c (Mac_Read_POST_Resource): Use unsigned long variables to read the lengths in POST fragments. Suggested by Mateusz Jurczyk <mjurczyk@google.com>. 2014-11-26 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> Fix Savannah bug #43539. * src/base/ftobjs.c (Mac_Read_POST_Resource): Fix integer overflow by a broken POST table in resource-fork. 2014-11-26 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> Fix Savannah bug #43538. * src/base/ftobjs.c (Mac_Read_POST_Resource): Fix integer overflow by a broken POST table in resource-fork. 2014-11-26 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * src/base/ftobjs.c (Mac_Read_POST_Resource): Avoid memory leak by a broken POST table in resource-fork. Return after freeing the buffered POST table when it is found to be broken. 2014-11-25 Werner Lemberg <wl@gnu.org> /: s/Invalid_Argument/Invalid_Size_Handle/ where appropriate. 2014-11-25 Werner Lemberg <wl@gnu.org> /: s/Invalid_Argument/Invalid_Stream_Handle/ where appropriate. 2014-11-25 Werner Lemberg <wl@gnu.org> /: s/Invalid_Argument/Invalid_Library_Handle/ where appropriate. 2014-11-25 Werner Lemberg <wl@gnu.org> /: s/Invalid_Argument/Invalid_Outline/ where appropriate. 2014-11-25 Werner Lemberg <wl@gnu.org> /: s/Invalid_Argument/Invalid_Face_Handle/ where appropriate. 2014-11-24 Werner Lemberg <wl@gnu.org> [Savannah bug #43682] Adjust some renderer callbacks. * src/raster/ftraster.c (ft_black_set_mode): Change return type to `int' to stay in sync with `FT_Renderer_SetModeFunc' prototype. * src/smooth/ftgrays.c (gray_raster_set_mode): New dummy function for orthogonality. (ft_grays_raster): Use it. 2014-11-25 Werner Lemberg <wl@gnu.org> [Savannah bug #43682] Properly handle missing return errors.

We use a cast to indicate that we intentionally ignore a function's return value. However, this doesn't apply to API functions where errors can only happen for trivially invalid input. * src/base/ftstroke.c (FT_Glyph_Stroke, FT_Glyph_StrokeBorder), src/base/ftsynth.c (FT_GlyphSlot_Embolden), src/cff/cffgload.c (cff_slot_load), src/pfr/pfrdrivr.c (pfr_get_kerning), src/type1/t1load.c (parse_encoding), src/type42/t42parse.c (t42_parse_encoding): Do it. 2014-11-25 Werner Lemberg <wl@gnu.org> [Savannah bug #43682] Change some signatures to `void' return type. * include/internal/pshints.h (PSH_Globals_SetScaleFunc), include/internal/sfnt.h (TT_Get_Metrics_Func), src/pshinter/pshglob.c (psh_globals_set_scale), src/pshinter/pshrec.c (ps_hints_init), src/sfnt/ttmtx.c (tt_face_get_metrics), src/truetype/ttinterp.c (TT_Goto_CodeRange, TT_Set_CodeRange, TT_Clear_CodeRange, TT_Done_Context, TT_Save_Context): Do it. * src/pshinter/pshglob.h, src/pshinter/pshrec.h, src/sfnt/ttmtx.h, src/truetype/ttgload.c (TT_Hint_Glyph), src/truetype/ttinterp.c (TT_Run_Context), src/truetype/ttinterp.h, src/truetype/ttobjs.c (tt_size_run_fpgm, tt_size_run_prep): Updated. 2014-11-24 Werner Lemberg <wl@gnu.org> Remove all code related to FT_MAX_CHARMAP_CACHEABLE.

Don't cast cmap init function pointers to an incompatible type. Without this patch, the number of parameters between declaration and the real signature differs. Calling such a function results in undefined behavior. ISO/IEC 9899:TC3 (Committee Draft September 7, 2007) 6.5.2.2 Function calls 9 If the function is defined with a type that is not compatible with the type (of the expression) pointed to by the expression that denotes the called function, the behavior is undefined. On certain platforms (c -> js with emscripten) this causes termination of execution or invalid calls because in the emscripten implementation, function pointers of different types are stored in different pointer arrays. Incorrect pointer type here results in indexing of an incorrect array. * src/cff/cffcmap.c (cff_cmap_encoding_init, cff_cmap_unicode_init), src/pfr/pfrcmap.c (pfr_cmap_init), src/psaux/t1cmap.c t1_cmap_standard_init, t1_cmap_expert_init, t1_cmap_custom_init, t1_cmap_unicode_init), src/winfonts/winfnt.c (fnt_cmap_init): Fix signature. 2014-11-24 Werner Lemberg <wl@gnu.org> [sfnt] Fix Savannah bug #43672. * src/sfnt/ttkern.c (tt_face_load_kern): Use correct value for minimum table length test. 2014-11-24 Werner Lemberg <wl@gnu.org> [type1, type42] Another fix for Savannah bug #43655. * src/type1/t1load.c (parse_charstrings), src/type42/t42parse.c (t42_parse_charstrings): Add another boundary testing. 2014-11-24 Werner Lemberg <wl@gnu.org> [docmaker] Formatting, copyright, improved documentation. * src/tools/docmaker/: No code changes besides trivial modifications. 2014-11-22 Werner Lemberg <wl@gnu.org> [bdf] Fix Savannah bug #43660. src/bdf/bdflib.c (_bdf_parse_glyphs) <"ENDFONT">: Check `_BDF_GLYPH_BITS'. 2014-11-22 Werner Lemberg <wl@gnu.org> [type42] Allow only embedded TrueType fonts. This is a follow-up to Savannah bug #43659. * src/type42/t42objs.c (T42_Face_Init): Exclusively use the `truetype' font driver for loading the font contained in the `sfnts' array. 2014-11-22 Werner Lemberg <wl@gnu.org> [type42] Fix Savannah bug #43659. * src/type42/t42objs.c (T42_Open_Face): Initialize `face->ttf_size'. * src/type42/t42parse.c (t42_parse_sfnts): Always set `face->ttf_size' directly. This ensures a correct stream size in the call to `FT_Open_Face', which follows after parsing, even for buggy input data. Fix error messages. 2014-11-22 Werner Lemberg <wl@gnu.org> [cff] Fix Savannah bug #43658. * src/cff/cf2ft.c (cf2_builder_lineTo, cf2_builder_cubeTo): Handle return values of point allocation routines. 2014-11-22 Werner Lemberg <wl@gnu.org> [sfnt] Fix Savannah bug #43656. * src/sfnt/ttcmap.c (tt_cmap4_validate): Fix order of validity tests. 2014-11-21 Werner Lemberg <wl@gnu.org> [type1, type42] Fix Savannah bug #43655. * src/type1/t1load.c (parse_charstrings), src/type42/t42parse.c (t42_parse_charstrings): Fix boundary testing. 2014-11-21 Werner Lemberg <wl@gnu.org> * src/pcf/pcfread.c (pcf_get_metrics): Sanitize invalid metrics. 2014-11-21 Werner Lemberg <wl@gnu.org> [ftlcdfil] Obey flow direction. * src/base/ftlcdfil.c (_ft_lcd_filter_fir, _ft_lcd_filter_legacy): Handle `up' flow. 2014-11-21 Werner Lemberg <wl@gnu.org> * src/base/ftbitmap.c (FT_Bitmap_Convert): Improve. This commit completes argument checks and adds support for different flow directions. 2014-11-21 Werner Lemberg <wl@gnu.org> * src/base/ftbitmap.c (FT_Bitmap_Copy): Improve. This commit adds argument checks and support for different flow directions. 2014-11-20 Werner Lemberg <wl@gnu.org> * src/base/ftbitmap.c (FT_Bitmap_New): Check argument. 2014-11-19 Werner Lemberg <wl@gnu.org> Change some fields in `FT_Bitmap' to unsigned type. This doesn't break ABI. * include/ftimage.h (FT_Bitmap): Make `rows', `width', `num_grays', `pixel_mode', and `palette_mode' unsigned types. * src/base/ftbitmap.c: Updated. (FT_Bitmap_Copy): Fix casts. * src/cache/ftcsbits.c, src/raster/ftraster.c, src/sfnt/pngshim.c: Updated. 2014-11-19 Werner Lemberg <wl@gnu.org> Make `FT_Bitmap_Convert' correctly handle negative `pitch' values. * src/base/ftbitmap.c (FT_Bitmap_Convert): Always use positive value for the pitch while copying data. Correctly set pitch sign in target bitmap. 2014-11-19 Werner Lemberg <wl@gnu.org> Minor code improvement in `FT_Bitmap_Embolden'. * src/base/ftbitmap.c (FT_Bitmap_Embolden) <FT_PIXEL_MODE_GRAY[24]>: Fix thinko. 2014-11-19 Alexei Podtelezhnikov <apodtele@gmail.com> * src/base/fttrigon.c: Use dedicated `FT_Angle' for arctan table. 2014-11-19 Behdad Esfahbod <behdad@behdad.org> Avoid compiler warnings on x86-64 for `FT_MulFix'. `FT_MulFix' takes `FT_Long' parameters as defined in `freetype.h', but several inline implementations of it in `ftcalc.h' take `FT_Int32' arguments. This is causing compiler warnings on x86-64: If parameters of type `FT_Fixed' (= `FT_Long') are passed to the inline implementation of this function, integer values are truncated from 64bit to 32bit. * include/internal/ftcalc.h (FT_MulFix) [FT_MULFIX_ASSEMBLER]: Add casts. 2014-11-15 Werner Lemberg <wl@gnu.org> [sfnt] Fix Savannah bug #43597. * src/sfnt/pngshim.c (Load_SBit_Png): Protect against too large bitmaps. 2014-11-12 Werner Lemberg <wl@gnu.org> [sfnt] Fix Savannah bug #43591. * src/sfnt/ttsbit.c (tt_sbit_decoder_init): Protect against addition and multiplication overflow. 2014-11-12 Werner Lemberg <wl@gnu.org> [sfnt] Fix Savannah bug #43590. * src/sfnt/ttload.c (check_table_dir, tt_face_load_font_dir): Protect against addition overflow. 2014-11-12 Werner Lemberg <wl@gnu.org> [sfnt] Fix Savannah bug #43589. * src/sfnt/sfobjs.c (woff_open_font): Protect against addition overflow. 2014-11-12 Werner Lemberg <wl@gnu.org> [sfnt] Fix Savannah bug #43588. * src/sfnt/ttcmap.c (tt_cmap8_validate, tt_cmap10_validate, tt_cmap12_validate, tt_cmap13_validate, tt_cmap14_validate): Protect against overflow in additions and multiplications. 2014-11-10 Alexei Podtelezhnikov <apodtele@gmail.com> [base] CORDIC improvements. The scaling between the hypotenuse and its CORDIC approximation is based on regression analysis. The smaller padding for `theta' is justified by its maximum error of less than 6. * src/base/fttrigon.c (ft_trig_downscale): Borrow code from ./ftcalc.c (ft_multo64), change linear intercept. (ft_trig_pseudo_polarize): Decrease `theta' padding. 2014-11-09 Werner Lemberg <wl@gnu.org> * src/base/ftstroke.c (ft_stroker_inside): Fix border intersections. One more place to check whether `radius' is zero. Problem reported by Marco Wertz <marco.wertz@gmx.de>. 2014-11-07 Werner Lemberg <wl@gnu.org> [bdf] Fix Savannah bug #43535. * src/bdf/bdflib.c (_bdf_strncmp): New macro that checks one character more than `strncmp'. s/ft_strncmp/_bdf_strncmp/ everywhere. 2014-11-06 Werner Lemberg <wl@gnu.org> [pcf] Fix Savannah bug #43548. * src/pcf/pcfread.c (pcf_get_encodings): Add sanity checks for row and column values. 2014-11-06 Werner Lemberg <wl@gnu.org> [pcf] Fix Savannah bug #43547. * src/pcf/pcfread.c (pcf_read_TOC): Check `size' and `offset' values. 2014-11-06 Werner Lemberg <wl@gnu.org> * src/pcf/pcfread.c (pcf_read_TOC): Avoid memory leak. 2014-11-03 Infinality <infinality@infinality.net> * src/truetype/ttsubpix.c (COMPATIBILITY_MODE_Rules): Updated. The previous commit deteriorates rendering of DejaVu and similar fonts; this gets compensated with this rule. 2014-11-03 Werner Lemberg <wl@gnu.org> * src/truetype/ttinterp.c (Ins_DELTAP): Fix subpixel hinting. Before this patch, it was impossible to ever call DELTAP[123] in subpixel hinting mode as described in the ClearType whitepaper; it only worked if in `compatibility mode'. However, compatibility mode essentially disables SHPIX, completely ruining hinting of ttfautohint output, for example. We now follow the whitepaper more closely so that DELTAP[123] instructions for touched points in the non-subpixel direction are executed. 2014-10-31 Alexei Podtelezhnikov <apodtele@gmail.com> [smooth] Improve code readability. * src/smooth/ftsmooth.c (ft_smooth_render_generic): Rearrange code. 2014-10-31 Alexei Podtelezhnikov <apodtele@gmail.com> [smooth] Reduce outline translations during rendering. * src/smooth/ftsmooth.c (ft_smooth_render_generic): Translate origin virtually by modifying cbox, actually translate outline if cumulative shift is not zero. 2014-10-30 Alexei Podtelezhnikov <apodtele@gmail.com> [smooth] Fix Savannah bug #35604 (cont'd). * src/smooth/ftsmooth.c (ft_smooth_render_generic): Remove checks and casts that became unnecessary after the variable type upgrades. 2014-10-29 Alexei Podtelezhnikov <apodtele@gmail.com> [smooth] Improve code readability. * src/smooth/ftsmooth.c (ft_smooth_render_generic): Rearrange code. 2014-10-29 Alexei Podtelezhnikov <apodtele@gmail.com> Unify hypotenuse approximations. * include/internal/ftcalc.h (FT_HYPOT): Move macro from here... * include/internal/ftobjs.h: ... to here, next to required `FT_ABS'. * src/smooth/ftgrays.c (gray_render_cubic): Use it here. 2014-10-25 Werner Lemberg <wl@gnu.org> [cff] Test valid darkening parameter macros in `ftoption.h'. We no longer need an otherwise unused typedef that can cause a gcc warning. Problem reported by Alexei. * src/cff/cffobjs.c (cff_driver_init): Use `CFF_CONFIG_OPTION_DARKENING_PARAMETER_XXX' macros directly. (SET_DARKENING_PARAMETERS): Removed. Compile time tests are now ... * devel/ftoption.h, include/config/ftoption.h: ... here. 2014-10-25 Alexei Podtelezhnikov <apodtele@gmail.com> Improve flat corner definition. * include/internal/ftcalc.h (FT_HYPOT): Macro to approximate Euclidean distance with the alpha max plus beta min algorithm. * src/base/ftcalc.c (ft_corner_is_flat): Use it instead of Taxicab metric. 2014-10-23 David Weiß <David.Weiss@ptvgroup.com> [build] Improve property file for vc2010. User-defined properties should be empty by default to prevent linker failures. * builds/windows/vc2010/freetype.user.props, builds/windows/vc2010/freetype.vcxproj: s/OptionsDirectory/UserOptionDirectory/. Comment out all user options. 2014-10-23 Werner Lemberg <wl@gnu.org> [cff] Work around bug in preprocessor of MSVC 2010. We have been hit by https://connect.microsoft.com/VisualStudio/feedback/details/718976/msvc-pr * devel/ftoption.h, include/config/ftoption.h: Replace `CFF_CONFIG_OPTION_DARKENING_PARAMETERS' with eight macros `CFF_CONFIG_OPTION_DARKENING_PARAMETER_{X,Y}{1,2,3,4}'. * src/cff/cffobjs.c (SET_DARKENING_PARAMETERS): Removed. We no longer need double expansion. (SET_DARKENING_PARAMETERS_0): Renamed to ... (SET_DARKENING_PARAMETERS): ... this. Update call. 2014-10-20 Werner Lemberg <wl@gnu.org> [sbit] Minor fixes. * src/sfnt/ttsbit.c (tt_face_load_sbit) [TT_SBIT_TABLE_TYPE_SBIX]: Accept overlay format also, but emit warning message in that case. (tt_sbit_decoder_load_metrics): Add missing newline to error message. (tt_sbit_load_sbix_image): Add `rgbl' graphic type (as used on iOS 7.1) to the list of unsupported formats. 2014-10-19 Alexei Podtelezhnikov <apodtele@gmail.com> [truetype] Clean up bytecode rounding. Zero distance does not have to be treated specially if you follow specifications and check the sign as the very last step of rounding. * src/truetype/ttinterp.c (Round_None, Round_To_Grid, Round_Down_To_Grid, Round_Up_To_Grid, Round_To_Double_Grid): Use macros when available, do not check for non-zero distance. (Round_To_Half_Grid, Round_Super, Round_Super_45): Ditto, return phase if sign changed. 2014-10-18 Alexei Podtelezhnikov <apodtele@gmail.com> [truetype] Unwrap engine compensation settings. * src/truetype/ttobjs.c (tt_size_init_bytecode): Updated. 2014-10-18 David Weiß <David.Weiss@ptvgroup.com> [build] Add property file to vc2010 project. This simplifies custom build configurations, especially for automated build environments. * builds/windows/vc2010/freetype.user.props: New configuration file. * builds/windows/vc2010/freetype.vcxproj: Include `freetype.user.props' and use its data fields. * builds/windows/vc2010/index.html: Updated. 2014-10-18 Werner Lemberg <wl@gnu.org> [autofit] Add blue-zone support for Telugu. This essentially moves the Telugu script from the `Indic' hinter to the `Latin' hinter. Note that this is a first shot and quite certainly needs refinements. * src/autofit/afblue.dat: Add blue zone data for Telugu. * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated. * src/autofit/afscript.h: Add Telugu standard characters and move data out of AF_CONFIG_OPTION_INDIC block. * src/autofit/afranges.c: Move Telugu data out of AF_CONFIG_OPTION_INDIC block. * src/autofit/afstyles.h: Update Telugu data; in particular, use AF_WRITING_SYSTEM_LATIN. 2014-10-18 David Wimsey <david@wimsey.us> [cmake] Add iOS build support. From Savannah patch #8497. * builds/cmake/iOS.cmake: New file. Universal binaries are built with both 32 and 64 bit arm architectures. * CMakeLists.txt (IOS_PLATFORM): New variable for running the iOS toolchain.

(cff_driver_init): Use new macros. 2014-10-14 Alexei Podtelezhnikov <apodtele@gmail.com> [truetype] Limit delta shift range. The valid range for delta shift is zero through six. Negative values are invalid according to https://developer.apple.com/fonts/TrueType-Reference-Manual/RM04/Chap4.html#delta%20shift * src/truetype/ttobjs.h (delta_shift, delta_base): Make unsigned. * src/truetype/ttinterp.h (DO_SDS): Throw an error if `delta_shift' is out of range. (Ins_DELTAP, Ins_DELTAC): Optimize for valid `delta_shift'. 2014-10-16 Werner Lemberg <wl@gnu.org> A better fix for Savannah bug #43392. Suggested by Doug Felt <dougfelt@gmail.com>. * src/sfnt/ttsbit.c (tt_sbit_decoder_load_metrics): Set `vertAdvance' to zero... * src/truetype/ttgload.c (TT_Load_Glyph): ... and set here a default value for `vertAdvance' based on `linearVertAdvance' in case `vertAdvance' is zero. Note that the previous computed ad-hoc value for `linearVertAdvance' was apparently not tested in a real-life situation. 2014-10-14 David Weiß <David.Weiss@ptvgroup.com> [build] Better optimization settings for vc2010 solution file. * builds/windows/vc2010/freetype.sln, builds/windows/vc2010/freetype.vcxproj: Updated. 2014-10-14 Werner Lemberg <wl@gnu.org> [autofit] Adjust Devanagari character range. * src/autofit/afranges.c (af_deva_uniranges): Omit characters that are common to all other Indic scripts. 2014-10-12 Werner Lemberg <wl@gnu.org> [sfnt] Fix Savannah bug #43392. * src/sfnt/ttsbit.c (tt_sbit_decoder_load_metrics): Don't let vertical metrics uninitialized. 2014-10-11 Alexei Podtelezhnikov <apodtele@gmail.com> [base] Small bbox correction. * src/base/ftbbox.c (FT_Outline_Get_BBox): Start from nonsense bbox instead of initial point that could be `off' in conic outlines. 2014-10-08 Alexei Podtelezhnikov <apodtele@gmail.com> [base] Fix Savannah bug #43356. * src/base/ftbbox.c (BBox_Move_To, BBox_Conic_To): Update bbox in case of implicit `to'. (BBox_Line_To): New emitter that does not update bbox. 2014-10-08 Alexei Podtelezhnikov <apodtele@gmail.com> [base] Introduce and use new macro `FT_UPDATE_BBOX' * src/base/ftbbox.c (FT_UPDATE_BBOX): New macro. (FT_Outline_Get_BBox): Use it here. 2014-10-02 Alexei Podtelezhnikov <apodtele@gmail.com> [base] Significant optimization of `ft_div64by32' We shift as many bits as we can into the high register, perform 32-bit division with modulo there, then work through the remaining bits with long division. This optimization is especially noticeable for smaller dividends that barely use the high register. * src/base/ftcalc.c (ft_div64by32): Updated. 2014-10-02 Dave Arnold <darnold@adobe.com> [cff] Fix Savannah bug #43271. * src/cff/cf2font.c (cf2_computeDarkening): Change overflow detection to use logarithms and clamp `scaledStem'. 2014-10-01 Alexei Podtelezhnikov <apodtele@gmail.com> * src/base/ftcalc.c: Remove miscellaneous type casts. 2014-10-01 Alexei Podtelezhnikov <apodtele@gmail.com> [base] Use more common `FT_MSB' implementation with masks. * src/base/ftcalc.c (FT_MSB): Updated. 2014-09-30 Alexei Podtelezhnikov <apodtele@gmail.com> [base] Clean up. * src/base/ftcalc.c (FT_MOVE_SIGN): New macro for frequently used code. 2014-09-25 Alexei Podtelezhnikov <apodtele@gmail.com> [base] Avoid unnecessary long division. This applies to `FT_MulDiv' but not to `FT_DivFix', where overflows or lack thereof are predicted accurately. * src/base/ftcalc.c (ft_div64by32): Improve readability. (FT_MulDiv, FT_MulDiv_No_Round) [!FT_LONG64]: Use straight division when multiplication stayed within 32 bits. 2014-09-24 Werner Lemberg <wl@gnu.org> [autofit] Minor clean-ups. * src/autofit/afhints.c (AF_FLAGS): Remove obsolete values. * src/autofit/afhints.c (af_glyph_hints_dump_points, af_glyph_hints_align_strong_points): Updated. * src/autofit/aflatin.c (af_latin_hints_link_segments, af_latin_hints_compute_segments), src/autofit/afcjk.c (af_cjk_hints_link_segments), src/autofit/aflatin2.c (af_latin2_hints_link_segments, af_latin2_hints_compute_segments): There are no longer fake segments since more than 10 years... 2014-09-22 Werner Lemberg <wl@gnu.org> [autofit] Minor code streamlining. * src/autofit/afhints.c (af_axis_hints_new_edge): Remove redundant initialization. 2014-09-19 Alexei Podtelezhnikov <apodtele@gmail.com> * src/base/ftcalc.c: Harmonize code. 2014-09-15 Alexei Podtelezhnikov <apodtele@gmail.com> [base] Tighten the overflow check in `FT_MulDiv'. * src/base/ftcalc.c (FT_MulDiv) [!FT_LONG64]: Updated. 2014-09-08 Alexei Podtelezhnikov <apodtele@gmail.com> Fix Savannah bug #43153. * src/psaux/psconv.c (PS_Conv_ToFixed): Add protection against overflow in `divider'. 2014-09-03 Alexei Podtelezhnikov <apodtele@gmail.com> [base] Tighten the overflow check in `FT_DivFix'.

Problem reported by Patrick Thomas <pthomas505@gmail.com>. 2014-04-22 Werner Lemberg <wl@gnu.org> * src/sfnt/pngshim.c (error_callback): s/longjmp/ft_longjmp/. 2014-04-20 Werner Lemberg <wl@gnu.org> [autofit] Fix Savannah bug #42148. The adaptation of the cjk auto-hinter module to blue stringsets in 2013-08-25 had three severe bugs. Mea culpa. 1. Contrary to the latin auto-hinter, characters for reference and overshoot values of a blue zone are specified separately. Due to the screwed-up change it didn't work at all. 2. A boolean comparison was erroneously replaced with a cast, causing invalid results with the `^' operator later on. The visual artifact caused by this problem is the topic of the bug report. 3. Two flag values were inverted, causing incorrect assignment of reference and overshoot values. * src/autofit/afblue.dat: Fix CJK bluestrings, introducing a new syntax to have both reference and overshoot characters in a single string. This is error #1. Add extensive comments. * src/autofit/afblue.hin (AF_BLUE_PROPERTY_CJK_FILL): Removed, no longer used. (AF_BLUE_PROPERTY_CJK_TOP, AF_BLUE_PROPERTY_CJK_HORIZ): Fix values. This is error #3. * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated. * src/autofit/afcjk.c (af_cjk_metrics_init_blues): Correct error #1. Use character `\|' to separate characters for reference and overshoot values. Improve tracing messages, synchronizing them with the latin auto-hinter. (af_cjk_hints_compute_blue_edges): Fix value of `is_top_right_blue'. This is error #2. (af_cjk_align_linked_edge): Add tracing message. * src/autofit/afcjk.h (AF_CJK_IS_FILLED_BLUE): Removed, no longer used. 2014-04-17 Werner Lemberg <wl@gnu.org> [autofit] More coverage fixes for complex scripts. * src/autofit/hbshim.c (af_get_coverage): Merge input glyph coverage of GSUB lookups into output coverage. Otherwise, ligatures are not handled properly. Don't check blue zone characters for default coverage. 2014-04-17 Werner Lemberg <wl@gnu.org> Make `FT_Get_SubGlyph_Info' actually work. * src/base/ftobjs.c (FT_Get_SubGlyph_Info): Return FT_Err_Ok if there is no error. 2014-04-15 Werner Lemberg <wl@gnu.org> [afblue.pl]: Minor improvements. * src/tools/afblue.pl: Allow whitespace before comments. Ignore whitespace in strings. 2014-04-14 Werner Lemberg <wl@gnu.org> [autofit] Improve coverage handling. * src/autofit/hbshim.c (af_get_coverage): Don't exclude glyphs appearing in the GPOS table if we are processing the default coverage. 2014-04-13 David Weber <weber.aulendorf@googlemail.com> [smooth] Fix stand-alone compilation. * src/smooth/ftgrays.c (FT_BEGIN_STMNT, FT_END_STMNT): Define. 2014-04-12 Werner Lemberg <wl@gnu.org> [autofit] Redesign the recognition algorithm of strong points. In particular, local extrema without horizontal or vertical segments are better recognized: + A + D \ / \ / \ / \ / \ + C \ / B +/ If the distances AB and CD are large, point B wasn't previously detected as an extremum since the `ft_corner_is_flat' function `swallowed' BC regardless of its direction, tagging point B as weak. The next iteration started at B and made `ft_corner_is_flat' swallow point C, tagging it as weak also, et voilà. To improve that, another pass gets now performed before calling `ft_corner_is_flat' to improve the `topology' of an outline: A sequence of non-horizontal or non-vertical vectors that point into the same quadrant are handled as a single, large vector. Additionally, distances of near points are now accumulated, which makes the auto-hinter handle them as if they were prepended to the next non-near vector. This generally improves the auto-hinter's rendering results. * src/autofit/afhints.c (af_glyph_hints_reload): Implement it. * src/autofit/afhints.h (AF_FLAGS): Remove no longer used flag `AF_FLAG_NEAR'. 2014-04-05 Werner Lemberg <wl@gnu.org> [autofit] Improve scoring algorithm for identifying stems. Problem reported by Karsten Lücke <karsten.luecke@kltf.de>. The new algorithm takes care of the width of stems: If the distance between two segments is larger than the largest stem width, the demerits quickly increase for larger distances. This improves hinting of slanted fonts (especially if the inner parts of serifs have non-horizontal `shoulders'), avoiding false stem links. * src/autofit/aflatin.c (af_latin_hints_link_segments): Use largest stem width (if available) to compute better demerits for distances between stems. (af_latin_hints_detect_features): Pass stem width array and array size. (af_latin_metrics_init_widths): Updated to use original algorithm. (af_latin_hints_apply): Updated to use new algorithm. * src/autofit/aflatin.h: Updated. * src/autofit/afcjk.c: Updated. 2014-04-03 Werner Lemberg <wl@gnu.org> Don't require `gzip' module for `sfnt'.

Split the single, incorrect Indic entry into separate scripts so that the covered ranges are the same: Bengali, Devanagari, Gujarati, Gurmukhi, Kannada, Limbu, Malayalam, Oriya, Sinhala, Sundanese, Syloti Nagri, Tamil, Telugu, and Tibetan. At the same time, remove entries for Meetei Mayek and Sharada – the Unicode ranges were incorrect (and nobody has complained about that), fonts are scarce for those scripts, and the Indic auto-hinter support is rudimentary anyways. * src/autofit/afscript.h: Updated, using AF_CONFIG_OPTION_INDIC and AF_CONFIG_OPTION_CJK. * src/autofit/afstyles.h (STYLE_DEFAULT_INDIC): New auxiliary macro. Use it, together with AF_CONFIG_OPTION_INDIC and AF_CONFIG_OPTION_CJK, to update. * src/autofit/afranges.c [AF_CONFIG_OPTION_INDIC]: Updated.

With this commit, the implementation of coverage handling is completed. * src/autofit/hbshim.c (af_get_coverage): Exit early if nothing to do. Reject coverages which don't contain appropriate glyphs for blue zones. 2014-01-03 Werner Lemberg <wl@gnu.org> [autofit] Fix handling of default coverages. * src/autofit/afglobal.c (af_face_globals_compute_style_coverage): First handle non-default coverages, then the default coverage of the default script, and finally the other default coverages. 2014-01-03 Werner Lemberg <wl@gnu.org> [autofit] Fix scaling of HarfBuzz shaping. * src/autofit/hbshim.c (af_get_char_index): Scale to units per EM. 2014-01-03 Werner Lemberg <wl@gnu.org> [autofit] Better ftgrid support. * src/autofit/afhints.c (af_glyph_hints_get_segment_offset): Add parameters `is_blue' and `blue_offset'. 2014-01-01 Werner Lemberg <wl@gnu.org> [autofit] Remove some styles. * src/autofit/afcover.h: Remove coverages for alternative fractions, denominators, numerators, and fractions. * src/autofit/afstyles.h (META_STYLE_LATIN): Updated. 2014-01-01 Werner Lemberg <wl@gnu.org> [autofit] Add more styles. * src/autofit/afstyles.h (STYLE_LATIN, META_STYLE_LATIN): New auxiliary macros; use them to define styles for Cyrillic, Greek, and Latin. * src/autofit/afcover.h: Remove coverage for oldstyle figures. Since those digits are used in combination with ordinary letters, it makes no sense to handle them separately. * src/autofit/afglobal.c (af_face_globals_get_metrics): Don't limit `options' parameter to 4 bits. 2014-01-01 Werner Lemberg <wl@gnu.org> [autofit] Fix style assignments to glyphs. * src/autofit/hbshim.c (af_get_coverage) [FT_CONFIG_OPTION_USE_HARFBUZZ]: Scan GPOS coverage of features also so that we can skip glyphs that have both GSUB and GPOS data. 2014-01-01 Werner Lemberg <wl@gnu.org> * src/autofit/hbshim.c: s/{lookups,glyphs}/gsub_{lookups,glyphs}/. 2014-01-01 Werner Lemberg <wl@gnu.org> [autofit] Implement and use `af_get_char_index' with HarfBuzz. * src/autofit/hbshim.c (COVERAGE) [FT_CONFIG_OPTION_USE_HARFBUZZ]: Redefine to construct HarfBuzz features.

Combining them, as originally envisioned, would lead to much more complicated code, as investigations have shown meanwhile. The major drawback is that we run out of available style slots much earlier. However, this is only a theoretical issue since we don't support a large number of scripts currently. * src/autofit/afcover.h: Replace `COVERAGE_{1,2,3}' macros with a single-element `COVERAGE' macro, sort the elements by the feature tags, and add entry for `ruby'. * src/autofit/aftypes.h: Updated. * src/autofit/hbshim.c: Updated. 2013-12-28 Werner Lemberg <wl@gnu.org> [autofit] Code shuffling to reduce use of cpp macros. * src/autofit/afglobal.c (af_face_globals_compute_style_coverage): Call `af_get_coverage' unconditionally. * src/autofit/autofit.c: Include `hbshim.c' unconditionally. * src/autofit/hbshim.c (af_get_coverage) [!FT_CONFIG_OPTION_USE_HARFBUZZ]: Provide dummy function. * src/autofit/hbshim.h: Provide function declarations unconditionally. 2013-12-28 Werner Lemberg <wl@gnu.org> [autofit] Add wrapper function for `FT_Get_Char_Index'.

We now use `hb_font' instead of `hb_face' since yet-to-come changes need this. * src/autofit/afglobal.h: Include `hbshim.h'.

(af_autofitter_init): Updated. 2013-12-27 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> [ftrfork] Fix the face order difference between POSIX and Carbon. The fragmented resources in Suitcase and .dfont should be reordered when `POST' resource for Type1 is being restored, but reordering of sfnt resources induces the different face order. Now the ordering is restricted to `POST' resource only, to prevent the different order issue (e.g. the face index in the fontconfig cache generated with Carbon framework is incompatible with that by FreeType 2 without Carbon framework.)

Coverages are the interface to the HarfBuzz library to access OpenType features for handling glyphs not addressable by the cmap. Right now, compilation of HarfBuzz is only added to the development build. A solution for standard build mode will be delayed until HarfBuzz gets split into two libraries to avoid mutual dependencies between FreeType and HarfBuzz. Note that this is only a first step in handling coverages, basically providing the framework only. Code for handling selected OpenType features (this is, actually using the data in `afcover.h') will follow. * devel/ftoption.h, include/config/ftoption.h (FT_CONFIG_OPTION_USE_HARFBUZZ): New macro. * src/autofit/hbshim.c, src/autofit/hbshim.h, src/autofit/afcover.h: New files. * src/autofit/afscript.h: Add HarfBuzz script name tags. * src/autofit/afstyles.h: Add default coverage enumeration values. * src/autofit/aftypes.h: Update use of `SCRIPT' and `STYLE' macros.

This large patch changes the header file directory layout from `include/freetype/...' to `include/...', effectively removing one level. Since the file `ft2build.h' is also located in `include' (and it stays there even after installation), all FreeType header files are now in a single directory. Applications that use (a) `freetype-config' or FreeType's `pkg-config' file to get the include directory for the compiler, and (b) the documented way for header inclusion like #include <ft2build.h> #include FT_FREETYPE_H ... don't need any change to the source code. * include/freetype/: Move up to... include/: ... this directory. builds/amiga/include/freetype/: Move up to... builds/amiga/include/: ... this directory. /: Essentially do `s@/freetype/@/@' where appropriate.

Two benefits: The allocated FDEF (and IDEF) array gets slightly smaller, and the `ttdebug' demo program has access to function numbers without additional costs. Fortunately, no changes to FontForge are necessary – this is the only external TrueType debugger I know of, but others may exist and should check the code accordingly. * src/truetype/ttinterp.h (TT_CallRec): Replace `Cur_Restart' and `Cur_End' with a pointer to the corresponding `TT_DefRecord' structure. * src/truetype/ttinterp.c (DO_JROT, DO_JMPR, DO_JROF, Ins_ENDF, Ins_CALL, Ins_LOOPCALL, Ins_UNKNOWN, TT_RunIns <Invalid_Opcode>): Updated. 2013-10-27 Werner Lemberg <wl@gnu.org> [sfnt] Implement support for `OS/2' table version 5.

When using `ADD' with an immediate operand, the instruction is actually `ADD Rd, Rn, #<imm12>', that is, the maximum of the immediate operand cannot exceed 4095. It will fail to compile with LLVM. However, in GCC, due to some legacy compatibility considerations, `ADD.W' will be automatically emitted when the immediate operand is larger than 4095. * builds/unix/ftconfig.in, include/freetype/config/ftconfig.h (FT_MulFix_arm) [__GNUC__]: Support clang compiler. * src/truetype/ttinterp.c (TT_MulFix14_arm) [__GNUC__]: Ditto. 2013-10-12 Werner Lemberg <wl@gnu.org> [autofit] Improve tracing of `latin' hinter. * src/autofit/aflatin.c (af_latin_metrics_init_blues): Report blue zone types. (af_latin_metrics_scale_dim): Report scaling changes due to x height alignment. Report scaled stroke width and blue zone values. 2013-10-03 Dave Arnold <darnold@adobe.com> * src/cff/cf2font.c (cf2_computeDarkening): Avoid division by zero. Note that the old code avoided using a region of the piecewise linear function where the slope was zero. The recovery was to use a different section of the function, which produced a different, incorrect amount of darkening. 2013-10-02 Darrell Bellert <darrell.bellert@hl.konicaminolta.us> * src/sfnt/ttload.c (tt_face_load_pclt): Fix `pclt_fields'. 2013-10-02 Dave Arnold <darnold@adobe.com> * src/cff/cf2font.c (cf2_computeDarkening): Initialize darkenAmount. This line was lost in commit 89ca1fd6 (from 2013-06-25). The effect is to use a previous darkening amount when producing an unhinted, unscaled outline. This can cause autohint samples in ftgrid and ftview to be based on darkened CFF outlines instead of unhinted, undarkened ones. 2013-09-29 Dave Arnold <darnold@adobe.com> Fix Savannah bug #39295. The bug was caused by switching to the initial hintmap (the one in effect when `moveto' executes) just before drawing the final element in the charstring. This ensured that the path was closed (in both Character Space and Device Space). But if the final element was a curve and if the final hintmap was different enough from the initial one, then the curve was visibly distorted. The first part of the fix is to draw the final curve using the final hintmap as specified by the charstring. This corrects the distortion but does not ensure closing in Device Space. It may require the rasterizer to automatically generate an extra closing line. Depending on the hintmap differences, this line could be from zero to a couple pixels in length. The second part of the fix covers the case where the charstring subpath is closed with an explicit line. We now modify that line's end point to avoid the distortion. Some glyphs in the bug report font (TexGyreHeros-Regular) that show the change are: 25ppem S (98) 24ppem eight (52) 25.5ppem p (85) Curves at the end of a subpath are no longer distorted. However, some of these glyphs have bad hint substitutions in the middle of a subpath, and these are not affected. The patch has been tested with a set of 106 fonts that shipped with Adobe Creative Suite 4, together with 756 Open Source CFF fonts from Google Fonts. There are 1.5 million glyphs, of which some 20k are changed with the fix. A sampling of a few hundred of these changes have been examined more closely, and the changes look good (or at least acceptable). * src/cff/cf2hints.h (CF2_GlyphPathRec): New element `pathIsClosing' to indicate that we synthesize a closepath line. * src/cff/cf2hints.c (cf2_glyphpath_init): Updated. (cf2_glyphpath_pushPrevElem): If closing, use first hint map (for `lineto' operator) and adjust hint zone. For synthesized closing lines, use end point in first hint zone. (cf2_glyphpath_lineTo): Take care of synthesized closing lines. In particular, shift the detection of zero-length lines from character space to device space. (cf2_glyphpath_closeOpenPath): Remove assertion. Updated. 2013-09-25 Werner Lemberg <wl@gnu.org> * src/autofit/aflatin.c (af_{grek,cyrl}_uniranges): Fix arrays. 2013-09-25 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> [bdf, pcf] Refuse non-zero face_index.

(af_latin_metrics_init_blues, af_latin_hint_edges): Improve tracing messages. 2013-08-26 Werner Lemberg <wl@gnu.org> Better tracing of loaded glyphs. Previously, the loading of a glyph was traced at level 4, if at all. With this change, all font loading routines emit a tracing message at level 1, making it easier to select tracing output (for example using F2_DEBUG="any:1 afhints:7 aflatin:7"). * src/bdf/bdfdrivr.c (BDF_Glyph_Load): Add tracing message. * src/cff/cffdrivr.c (cff_glyph_load): Ditto. * src/cff/cffgload.c (cff_decoder_prepare): Improve tracing messages. * src/cid/cidgload.c (cid_load_glyph): Use level 1 for tracing message. * src/pcf/pcfdrivr.c (PCF_Glyph_Load): Ditto. * src/pfr/pfrobjs.c (pfr_slot_load): Add tracing message. * src/truetype/ttgload.c (TT_Load_Glyph): Ditto. * src/type1/t1gload.c (T1_Load_Glyph): Ditto. * src/type42/t42objs.c (T42_GlyphSlot_Load): Ditto. * src/winfonts/winfnt.c (FNT_Load_Glyph): Ditto. 2013-08-26 Werner Lemberg <wl@gnu.org> [autofit] Fix script selection. * src/autofit/afglobal.c (af_face_globals_get_metrics): Use `AF_SCRIPT_DFLT', not value 0.

Change loops to use offsets (in file `afblue.h') into the new arrays `af_blue_stringsets' and `af_blue_strings' (in file `afblue.c'). Instead of three dimensions (as used in the old blue string array) we now use properties to do the same, saving one loop nesting level. src/autofit/afcjk.h: Remove old enumeration values superseded by the new data in `afblue.h'. (AF_CJK_IS_TOP_BLUE, AF_CJK_IS_HORIZ_BLUE, AF_CJK_IS_FILLED_BLUE, AF_CJK_IS_RIGHT_BLUE): New macros, to be used in `af_cjk_metrics_init_blues'.

The idea is to have a central file which gets processed by a Perl script to create proper `.c' and `.h' files using templates. There are two other reasons to do that: . The data file should be easily readable. We use UTF-8 encoding which then gets converted to single bytes. . Since the number of supported scripts will increase soon, the current usage of blue string arrays is a waste of space. Using the Perl script it is possible to imitate jagged arrays, defining enumeration constants as offsets into the arrays. This commit only adds files without changing any functionality. * src/autofit/afblue.dat: New data file. * src/tools/afblue.pl: New Perl script for processing `afblue.dat'. * src/autofit/afblue.cin, src/autofit/afblue.hin: New template files for... * src/autofit/afblue.c, src/autofit/afblue.c: New source files. To avoid a dependency on Perl, we add them too. 2013-08-19 Alexei Podtelezhnikov <apodtele@gmail.com> [base] Enable new algorithm for `BBox_Cubic_Check'. * src/base/ftbbox.c: Enable new BBox_Cubic_Check algorithm, remove the old one.

Fix test for INDEX structures which have one or more empty entries at the end. 2013-08-05 Werner Lemberg <wl@gnu.org> Fix gcc pragmas, part 2. * src/truetype/ttinterp.c (TT_MulFix14_long_long, TT_DotFix14_long_long): `#pragma gcc diagnostic {push,pop}' has been introduced with gcc version 4.6. 2013-08-05 Werner Lemberg <wl@gnu.org> Fix gcc pragmas. * src/truetype/ttinterp.c (TT_MulFix14_long_long, TT_DotFix14_long_long): Older gcc versions don't accept diagnostic pragmas within a function body. 2013-08-05 Werner Lemberg <wl@gnu.org> Fix Savannah bug #39700. * builds/unix/ftconfig.h: Synchronize with `include/freetype/config/ftconfig.h'. * builds/vms/ftconfig.h: Ditto. Make the differences to the master `ftconfig.h' file as small as possible for easier maintenance. 2013-08-05 Werner Lemberg <wl@gnu.org> [autofit] Improve handling of `near' points. Points which are very near to each other are now marked as such. The `weak' flag is then computed by using the `in' vector of the first and the `out' vector of the last point of a group of near points. For example, this fixes the rendering of glyph `Oslash' in `Roboto-Thin.ttf'. * src/autofit/afhints.h (AF_Flags): New value `AF_FLAGS_NEAR'. * src/autofit/afhints.c (af_glyph_hints_reload): Introduce the heuristic value `near_limit' to decide whether the current point is near to the previous one, then set `AF_FLAG_NEAR' accordingly. Store good `in' vector (of last non-near point) in `last_good_in_{x,y}' and use it as an argument to `ft_corner_is_flat' if necessary. 2013-08-02 Werner Lemberg <wl@gnu.org> * include/freetype/ftcffdrv.h: Improve documentation. This is based on blog entries from David Lemon and Dave Arnold (both from Adobe) with kind permission. Dave also helped in proof-reading. 2013-08-02 Werner Lemberg <wl@gnu.org> [autofit] Move declaration of scripts into separate file. This has the benefit that we don't need to duplicate the data at different places. * src/autofit/afscript.h: New file. * src/autofit/aftypes.h (AF_Script): Include `afscript.h' to define the enumeration values. * src/autofit/afglobal.c: Include `afscript.h' to get the script specific header files.

This patch adds a new top level to the auto-hinter's script class hierarchy. It defines `writing systems' which can contain multiple scripts. For example, the `latin' writing system (in file `aflatin.c') is able to support scripts like Latin, Cyrillic, Armenian, etc., which can be handled similarly. Scripts are now named using four-letter OpenType tags. src/autofit/aftypes.h (AF_ScriptClassRec): Move relevant members to... (AF_WritingSystemClassRec): This new structure.

The old code (essentially unchanged since the very beginning) incorrectly handled this configuration x -o- x / \ / \ / \ o o as flat and this o o / / x\| x\| \| \| o---------------o as round. (`o' and `x' are on and off points, respectively). This is a major change which should improve the rendering results enormously for many TrueType fonts, especially in the range approx. 20-40ppem, fixing the appearance of many overshoots. * src/autofit/aflatin.c (af_latin_metrics_init_blues): Look at the first and last points of the segment, not the points right before and after. 2013-07-19 Behdad Esfahbod <behdad@google.com> [sfnt] `sbix' fix-ups. * src/sfnt/sfobjs.c (sfnt_load_face): Apple's `sbix' color bitmaps are rendered scaled and then the `glyf' outline rendered on top.

When building for ARMv7 with thumb2 instructions, the optimized `FT_MulFix_arm' assembly routine was not being used. The reason for this is in the `ftconfig.h' header, namely: - The assembly routine uses the `smull' instruction which is not available when generating Thumb-1 machine code. It is available in Thumb-2 mode, though. - The header was written a long time ago before Thumb-2 became widely popular (e.g. with Android). So it simply doesn't use the assembly routine if the `__thumb__' built-in macro is defined. - When compiling in Thumb-2 mode, the compiler will define both `__thumb__' and `__thumb2__'. By checking for `(__thumb2__ \|\| !__thumb__)', we ensure that the assembly routine is only avoided when generating Thumb-1 code.

(FT_Init_FreeType): Updated. 2016-07-09 Werner Lemberg <wl@gnu.org> Add function `ft_property_string_set'. This is a preparation for handling an `FREETYPE_PROPERTIES' environment variable to control (some) driver properties. No change in functionality. * src/base/ftobjs.c (ft_property_do): Add `value_is_string' parameter. (ft_property_string_set): New function.

They were incorrect since the migration of the header files, on 2015-06-22. Either inexisting include/cache (removed on 2006-03-20) is not needed to be listed explicitly. Now ftmac.h is scanned only in the case of Mac OS & Mac OS X. 2016-07-08 Alexei Podtelezhnikov <apodtele@gmail.com> [smooth] Sub-banding protocol revision. Rasterization sub-banding is utilized at large sizes while using a rather small fixed memory pool. Indeed it is possible to make an educated guess how much memory is necessary at a given size for a given glyph. It turns out that, for a large majority of European glyphs, you should store about 8 times more boundary pixels than their height. Or, vice versa, if your memory pool can hold 800 pixels the band height should be 100 and you should sub-band anything larger than that. Should you still run out of memory, FreeType bisects the band but you have wasted some time. This is what has been implemented in FreeType since the beginning. It was overlooked, however, that the top band could grow to twice the default band size leading to unnecessary memory overflows there. This commit fixes that. Now the bands are distributed more evenly and cannot exceed the default size. Now the magic number 8 is really suitable for rather simple European scripts. For complex Chinese logograms the magic number should be 13 but that is subject for another day. * src/smooth/ftgrays.c (gray_convert_glyph): Revise sub-banding protocol. 2016-07-07 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> [mac] Fix Savannah bug #48417. Mac OS X linker throws errors when `-exported_symbol_list' input file includes non-existing symbols. Reported by Ryan Schmidt. * builds/exports.mk: Exclude ftmac.h from the headers for apinames by default. Include it when ftmac.c would be compiled. 2016-07-06 Werner Lemberg <wl@gnu.org> * src/truetype/ttinterp.c (TInstruction_Function): Removed, unused. 2016-07-05 Werner Lemberg <wl@gnu.org> * Version 2.6.4 released. ========================= Tag sources with `VER-2-6-4'. * docs/VERSION.TXT: Update documentation and bump version number to 2.6.4. * README, Jamfile (RefDoc), builds/windows/vc2005/freetype.vcproj, builds/windows/vc2005/index.html, builds/windows/vc2008/freetype.vcproj, builds/windows/vc2008/index.html, builds/windows/vc2010/freetype.vcxproj, builds/windows/vc2010/index.html, builds/windows/visualc/freetype.dsp, builds/windows/visualc/freetype.vcproj, builds/windows/visualc/index.html, builds/windows/visualce/freetype.dsp, builds/windows/visualce/freetype.vcproj, builds/windows/visualce/index.html, builds/wince/vc2005-ce/freetype.vcproj, builds/wince/vc2005-ce/index.html, builds/wince/vc2008-ce/freetype.vcproj, builds/wince/vc2008-ce/index.html: s/2.6.3/2.6.4/, s/263/264/. * include/freetype/freetype.h (FREETYPE_PATCH): Set to 4. * builds/unix/configure.raw (version_info): Set to 18:4:12. * CMakeLists.txt (VERSION_PATCH): Set to 4. * docs/CHANGES: Updated. 2016-07-05 Werner Lemberg <wl@gnu.org> * src/pfr/pfrsbit.c (pfr_lookup_bitmap_data): Fix compiler warning. 2016-07-04 Alexei Podtelezhnikov <apodtele@gmail.com> [smooth] Variable type revision (part 2). * src/smooth/ftgrays.c (TArea): Restore original definition as `int'. (gray_render_line) [FT_LONG64]: Updated. (gray_convert_glyph): 32-bit band bisection stack should be 32 bands. (gray_convert_glyph_inner): Trace successes and failures. 2016-07-04 Werner Lemberg <wl@gnu.org> [autofit] Handle single-point contours as segments. Doing so allows us to link them to edges – some fonts like `NotoSansGurmukhi-Regular' have such isolated points sitting exactly on other outlines. * src/autofit/aflatin.c (af_latin_hints_compute_segments): Don't ignore one-point contours but handle them specially as one-point segments.

This patch restores original `TCoord' definition as `int' so that the rendering pool is used more efficiently on LP64 platforms (unix). * src/smooth/ftgrays.c (gray_TWorker, TCell, gray_TBand): Switch some fields to `TCoord'. (gray_find_cell, gray_render_scanline, gray_render_line, gray_hline, gray_sweep, gray_convert_glyph): Updated. 2016-06-28 Alexei Podtelezhnikov <apodtele@gmail.com> [smooth] Minor clean-ups. * src/smooth/ftgrays.c (gray_TWorker): Remove redundant `ycount'.

Only reject `0xFFFF' as an invalid encoding offset. 2016-06-25 Werner Lemberg <wl@gnu.org> [truetype] Really fix deallocation in case of error (#47726). * src/truetype/ttgload.c (load_truetype_glyph): Thinko; initialize `outline.points' also. 2016-06-23 Alexei Podtelezhnikov <apodtele@gmail.com> [smooth] Consolidate memory management. * src/smooth/ftgrays.c (gray_init_cells): Remove function. (gray_TWorker): Remove fields that become local variables. (gray_raster_render): Move rendering buffer declaration from here. (gray_convert_glyph): ... to here and update accordingly. 2016-06-22 Alexei Podtelezhnikov <apodtele@gmail.com> [smooth] Consolidate boundary checks. Removing the checks from `gray_hline' shaves 1% off rendering speed. * src/smooth/ftgrays.c [STANDALONE_]: Duplicate `FT_MIN' and `FT_MAX'. (gray_TWorker): No need to store `clip_box'. (gray_hline): Remove unnecessary boundary checks. (gray_convert_glyph): Move boundary checks from here.

With this change we change the files only if there are real modifications, so we can avoid recompilations. 2016-06-09 Werner Lemberg <wl@gnu.org> [bdf] Check number of properties (#48166). * src/bdf/bdflib.c (_bdf_parse_start): Implement. 2016-06-08 Alexei Podtelezhnikov <apodtele@gmail.com> [smooth] Re-enable new line renderer on 64-bit archs. * src/smooth/ftgrays.c (gray_render_line): Conditionally re-enable new implementation, where it is safe from overflows. 2016-06-08 Alexei Podtelezhnikov <apodtele@gmail.com> [smooth] Minor clean-ups. * src/smooth/ftgrays.c (gray_dump_cells): Move out of the way. (gray_render_span): Remove spurious casts and streamline. 2016-06-07 Werner Lemberg <wl@gnu.org> [autofit] Add support for Ethiopic script. * src/autofit/afblue.dat: Add blue zone data for Ethiopic. * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated. * src/autofit/afscript.h: Add Ethiopic standard characters. * src/autofit/afranges.c: Add Ethiopic data. * src/autofit/afstyles.h: Add Ethiopic data. 2016-06-07 Werner Lemberg <wl@gnu.org> [autofit] Fix compilation with VS2016 (#48126). This compiler doesn't recognize the end-of-comment sequence `/' if it immediately follows non-ASCII characters. src/autofit/afscript.h: Ensure whitespace before `/'. 2016-06-04 Werner Lemberg <wl@gnu.org> Fix a test for named instances (#48122). This was missed while giving negative face indices an extended meaning. src/base/ftobjs.c (Mac_Read_sfnt_Resource): Implement. 2016-05-31 Nikolaus Waxweiler <madigens@gmail.com> [truetype] Let SHPIX move points in the twilight zone in v40. * src/truetype/ttinterp.c (Ins_SHPIX): Allow SHPIX to move points in the twilight zone. Otherwise, treat SHPIX the same as DELTAP. Unbreaks various fonts such as older versions of Rokkitt and DTL Argo T Light that would glitch severely after calling ALIGNRP after a blocked SHPIX. 2016-05-30 Werner Lemberg <wl@gnu.org> [type42] Support `CharStrings' entry format as created by LilyPond. * src/type42/t42parse.c (t42_parse_charstrings): Handle entries having the format (foo) cvn 12345 def 2016-05-28 Werner Lemberg <wl@gnu.org> * src/autofit/afranges.c: Remove `UL' postfix from hex numbers. Suggested by Alexei. `UL' is only needed for 16bit compilers, but it seems noone is using this anymore (and we no longer test whether FreeType compiles in such an environment). Otherwise, it is easy to add the postfix to the `AF_UNICODE_RANGE' macro. 2016-05-26 Alexei Podtelezhnikov <apodtele@gmail.com> [smooth] Shrink bisection stack. The convergence of Bézier flatteners is fast with the deviation from straight line being asymptotically cut 4-fold on each bisection. This justifies smaller bisection stack size. * src/smooth/ftgrays.c (gray_TWorker): Remove common `bez_stack'. (gray_render_conic): Create and use conic `bez_stack'. Move back the band analysis from... (gray_conic_to): ... here. (gray_render_cubic): Create and use cubic `bez_stack'. Move back the band analysis from... (gray_cubic_to): ... here. (gray_move_to): Updated. 2016-05-25 Werner Lemberg <wl@gnu.org> [autofit] Fixes for Armenian and Gujarati ranges. * src/autofit/afranges.c (af_armn_uniranges): Corrected. (af_guru_nonbase_uniranges): Make U+0A3E a base character. 2016-05-24 Werner Lemberg <wl@gnu.org> [autofit] Add support for Armenian script. * src/autofit/afblue.dat: Add blue zone data for Armenian. * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated. * src/autofit/afscript.h: Add Armenian standard characters. * src/autofit/afranges.c: Add Armenian data. * src/autofit/afstyles.h: Add Armenian data. 2016-05-23 Werner Lemberg <wl@gnu.org> * builds/unix/unix-cc.in (LINK_LIBRARY): Use `-export-symbols'. This was commented about 10 years ago – I think the reason then to disable libtool's `-export-symbols' option was to give some badly programmed applications access to internal FreeType functions. I believe that we should no longer take care of such programs; the number of symbols exported should be rather restricted as much as possible. 2016-05-22 Werner Lemberg <wl@gnu.org> [autofit] Add blue-zone support for Gurmukhi script. This essentially moves the Gurmukhi script from the `Indic' hinter to the `Latin' hinter. * src/autofit/afblue.dat: Add blue zone data for Gurmukhi. * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated. * src/autofit/afscript.h: Add Gurmukhi standard characters and move data out of AF_CONFIG_OPTION_INDIC block. * src/autofit/afranges.c: Move Gurmukhi data out of AF_CONFIG_OPTION_INDIC block. * src/autofit/afstyles.h: Update Gurmukhi data; in particular, use AF_WRITING_SYSTEM_LATIN. 2016-05-21 Werner Lemberg <wl@gnu.org> Minor clang++ fixes. * src/base/ftobjs.c (FT_Add_Module), src/psaux/psobjs.c (ps_parser_load_field), src/type1/t1load.c (parse_subrs): Add initializer. * src/cache/ftccache.h (FTC_CACHE_TRYLOOP_END): Avoid implicit conversion from NULL to boolean. 2016-05-21 Werner Lemberg <wl@gnu.org> Work around a bug of the C 8.0.0.1 compiler on AIX 5.3 (#47955). * include/freetype/internal/ftmemory.h (cplusplus_typeof): Use braces for `extern "C++"'. 2016-05-17 Nikolaus Waxweiler <madigens@gmail.com> [truetype] Make TT_LOADER_SET_PP support subpixel hinting [3/3]. * src/truetype/ttgload.c (TT_LOADER_SET_PP): Replace macro with... (tt_loader_set_pp): ... this new function. Update all callers. 2016-05-17 Nikolaus Waxweiler <madigens@gmail.com> [truetype] New implementation of v38 bytecode interpreter [2/3]. This patch actually modifies the bytecode interpreter. See added comments in `ttinterp.h' for more information on this and the following commit in the series. * src/truetype/ttinterp.c (SUBPIXEL_HINTING): Replaced by... (NO_SUBPIXEL_HINTING, SUBPIXEL_HINTING_INFINALITY, SUBPIXEL_HINTING_MINIMAL): ...new macros. (Direct_Move, Direct_Move_X, Direct_Move_Y): Handle backward compatibility. Updated.

(TT_RunIns): Handle backward compatibility mode. Updated. 2016-05-17 Nikolaus Waxweiler <madigens@gmail.com> [truetype] New implementation of v38 bytecode interpreter [1/3]. This patch prepares data structures and the like. See added comments in `ttinterp.h' for more information on this and the following commits in the series. * devel/ftoption.h, include/freetype/config/ftoption.h (TT_CONFIG_OPTION_SUBPIXEL_HINTING): Assign values to differentiate between subpixel versions.

(cid_parser_new): Fix and document algorithm. 2016-05-16 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> [truetype] Improve the recursive reference detector. The previous fix for #46372 misunderstood a composite glyph referring same component twice as a recursive reference. See the discussion https://lists.gnu.org/archive/html/freetype/2016-05/msg00000.html Thanks to Khaled Hosny for finding this issue. * src/truetype/ttgload.c (ft_list_get_node_at): A function to get the i-th node from FT_List. (load_truetype_glyph): In the traversal scan of the reference tree in the composite glyph, we clear the nodes filled by previous sibling chain. 2016-05-07 Werner Lemberg <wl@gnu.org> [cache] Allow value 0 for face ID. We never dereference `face_id', and some implementations might use a running number instead of a pointer. Additionally, disallowing value zero was undocumented. * src/cache/ftccmap.c (FTC_CMapCache_Lookup), src/cache/ftcmanag.c (FTC_Manager_LookupFace, FTC_Manager_RemoveFaceID): Remove test for `face_id'. 2016-05-05 Alexei Podtelezhnikov <apodtele@gmail.com> [smooth] More efficient accounting of conic splits and draws. A single decrement counter of segments to draw, instead of an array, contains all the information necessary to decide when to split and when to draw a conic segment. The number of splits before each draw is equal to the number of trailing zeros in the counter. * src/smooth/ftgrays.c (gray_TWorker): Remove `lev_stack'. (gray_render_conic): Updated to use decrement counter of segments. 2016-05-05 Werner Lemberg <wl@gnu.org> [cff, truetype] Fix logic for `FT_Property_Set'. Otherwise some properties could be set to arbitrary values, which is harmless, but querying could give wrong positive results. * src/cff/cffdrivr.c (cff_property_set) [hinting-engine], * src/truetype/ttdriver.c (tt_property_set) [interpreter-version]: Only allow defined values. 2016-04-25 Werner Lemberg <wl@gnu.org> [autofit] Add blue-zone support for Gujarati script.

Suggested by Akaki Razmadze <razmadzekoko@gmail.com>. * src/autofit/afblue.dat (AF_BLUE_STRING_GEORGIAN_MKHEDRULI_BOTTOM): Updated. * src/autofit/afblue.c: Regenerated. 2016-04-16 David Capello <davidcapello@gmail.com> [cmake] Honor SKIP_INSTALL_* settings (as used in zlib). As FreeType depends on zlib, if we don't install zlib (e.g., because we defined SKIP_INSTALL_ALL), FreeType cannot be installed, too (cmake triggers an error saying that FreeType cannot be installed because zlib target isn't in the export set). * CMakeLists.txt: Honor `SKIP_INSTALL_HEADERS', `SKIP_INSTALL_LIBRARIES', and `SKIP_INSTALL_ALL' settings. 2016-04-16 Behdad Esfahbod <behdad@behdad.org> [truetype] Another fix for non-intermediate GX tuples. * src/truetype/ttgxvar.c (ft_var_apply_tuple): Add some missing cases. 2016-04-12 Alexei Podtelezhnikov <apodtele@gmail.com> Remove forgotten macro. * include/freetype/internal/internal.h [FT_INTERNAL_POSTSCRIPT_GLOBALS_H]: Remove. 2016-04-09 Werner Lemberg <wl@gnu.org> [autofit] Add support for Georgian scripts. Georgian is problematic, since `uppercase' forms of Mkhedruli (called Mtavruli) are not yet defined in Unicode, which means that proper blue zones can't be defined. However, there is already a proposal submitted to Unicode; see https://www.unicode.org/L2/L2016/16034-n4707-georgian.pdf Additionally, due to historical reasons, Unicode treats Khutsuri as the same script as Mkhedruli, and so does OpenType. However, since the two scripts have completely different shapes it can happen that blue zones differ considerably. The tag `geok' used here (derived from ISO 15924) to differentiate the two scripts is not an OpenType tag in use. If we now have a font that contains both glyphs for Mkhedruli and Khutsuri, and it uses OpenType features for both also, HarfBuzz unavoidably treats all glyphs as `geor'. As a consequence, blue zones for `geok' are not used for glyphs involved in the OpenType features. An issue not yet resolved is which OpenType feature should be used to access Mtavruli glyph shapes; right now, FreeType doesn't set up support for them, but it is easy to add them later on as soon as more information is available. * src/autofit/afblue.dat: Add blue zone data for Georgian. * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated. * src/autofit/afscript.h: Add Georgian standard characters. * src/autofit/afranges.c: Add Georgian data. * src/autofit/afstyles.h: Add Georgian data. 2016-04-05 Werner Lemberg <wl@gnu.org> [autofit] Provide dummy blue zone for pseudo script `none'.

Patch taken from ttfautohint, commit 071ae2c00e0d67f9d19418f4fade1c23d27dc185. There were two bugs. - We now use non-standard script tags like `khms' for special purposes. However, HarfBuzz maps such tags to `DFLT', and without this commit the associated lookups were incorrectly assigned to the non-standard tags. - Let's assume we have a Bengali font, and the font's `DFLT' script tag handles the necessary lookups for Bengali, too. Without this commit, the `DFLT' lookups were assigned to ttfautohint's default script (usually `latn') before the standard lookups for Bengali were handled.

This feature is mainly for Khmer: The idea is to avoid a clash between the top of subscript glyphs and the bottom of normal baseline glyphs. This only works for character clusters mapped to multiple glyphs. * src/autofit/afblue.dat: Add subscript top blue zone for Khmer. * src/autofit/afblue.hin (AF_BLUE_PROPERTY_LATIN_SUB_TOP): New macro. * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated. * src/autofit/aflatin.h (AF_LATIN_IS_SUB_TOP_BLUE, AF_LATIN_BLUE_SUB_TOP): New macros. * src/autofit/aflatin.c (af_latin_metrics_init_blues): Handle new blue zone property.

We split Khmer into two auto-hinter scripts: `Khmer' (`khmr') and `Khmer symbols' (`khms', U+19E0-U+19FF). * src/autofit/afblue.dat: Add blue zone data for Khmer. * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated. * src/autofit/afscript.h: Add Khmer standard characters. * src/autofit/afranges.c: Add Khmer data. * src/autofit/afstyles.h: Add Khmer data. 2015-12-06 Werner Lemberg <wl@gnu.org> [autofit] Rewrite HarfBuzz interface to support character clusters. Scripts like Khmer have blue zones that can't be directly represented by Unicode characters. Instead, it is necessary to let HarfBuzz convert character clusters into proper glyph representation forms, then deriving the blue zone information from the resulting glyphs. * src/autofit/hbshim.c, src/autofit/hbshim.h: Replaced by... * src/autofit/afshaper.c, src/autofit/afshaper.h: ... these two new files, providing a new API to access HarfBuzz. The new API manages a HarfBuzz buffer with `af_shaper_buf_create' and `af_shaper_buf_destroy'. The buffer receives a UTF8 encoded string with function `af_shaper_get_cluster', and the resulting glyph data (indices, advance widths, vertical offsets) can be iteratively accessed with function `af_shaper_get_elem'. * src/autofit/afcjk.c (af_cjk_metrics_init_widths, af_cjk_metrics_init_blues, af_cjk_metrics_check_digits): Updated. * src/autofit/aflatin.c (af_latin_metrics_init_widths, af_latin_metrics_init_blues, af_latin_metrics_check_digits): Updated. * include/freetype/internal/fttrace.h: s/afharfbuzz/afshaper/. * src/autofit/afglobal.c: s/hbshim.h/afshaper.h/. (af_face_globals_compute_style_coverage): Updated. * src/autofit/afglobal.h: s/hbshim.h/afshaper.h/. * src/autofit/autofit.c: s/hbshim.c/afshaper.c/. * src/autofit/Jamfile, src/autofit/rules.mk (AUTOF_DRV_SRC): Updated. 2015-12-06 Werner Lemberg <wl@gnu.org> [autofit] Prepare forthcoming changes. This makes it easier to control the commits. * src/autofit/aflatin.c (af_latin_metrics_init_blues): Add dummy loop. No functional change. 2015-12-06 Werner Lemberg <wl@gnu.org> [autofit] Use string of standard characters. This is more flexible; additionally, it would allow character clusters. * src/autofit/aftypes.h (SCRIPT, AF_DEFINE_SCRIPT_CLASS): Updated. (AF_ScriptClassRec): Replace `standard_char[123]' with `standard_charstring'. * src/autofit/afscript.h: Replace last three character arguments of the `SCRIPT' calls with a string parameter, holding the standard characters (in UTF-8 encoding) separated with spaces. * src/autofit/afglobal.c, src/autofit/afglobal.h, src/autofit/afpic.c, src/autofit/afranges.c, src/autofit/hbshim.c (SCRIPT): Updated. * src/autofit/afcjk.c (af_cjk_metrics_init_widths), src/autofit/aflatin.c (af_latin_metrics_init_widths): Updated. 2015-12-05 Werner Lemberg <wl@gnu.org> * src/autofit/afblue.dat: Separate blue zone characters with spaces. Another preparation for character cluster support. * src/autofit/afblue.c, src/autofit.afblue.h: Regenerated. 2015-12-05 Werner Lemberg <wl@gnu.org> * src/tools/afblue.pl (convert_ascii_chars): Don't ignore spaces. Instead, reduce multiple spaces to a single one. We need this later for supporting character clusters in `afblue.dat'. 2015-12-05 Werner Lemberg <wl@gnu.org> * src/autofit/afblue.hin (GET_UTF8_CHAR): Use `do...while(0)'. * src/autofit/afblue.h: Regenerated. 2015-12-05 Werner Lemberg <wl@gnu.org> * src/autofit/afwarp.c: s/INT_MIN/FT_INT_MIN/. 2015-12-03 Werner Lemberg <wl@gnu.org> * builds/unix/install.mk (install): Remove stale `ft2build.h'. 2015-12-01 Werner Lemberg <wl@gnu.org> [type1] Avoid dangling pointer (#46572). * src/type1/t1afm.c (T1_Read_Metrics): Properly reset `face->afm_data'. 2015-11-28 Alexei Podtelezhnikov <apodtele@gmail.com> * include/freetype/ftlcdfil.h: Documentation tweak. 2015-11-28 Werner Lemberg <wl@gnu.org> * Version 2.6.2 released. ========================= Tag sources with `VER-2-6-2'. * docs/VERSION.DLL: Update documentation and bump version number to 2.6.2. * README, Jamfile (RefDoc), builds/windows/vc2005/freetype.vcproj, builds/windows/vc2005/index.html, builds/windows/vc2008/freetype.vcproj, builds/windows/vc2008/index.html, builds/windows/vc2010/freetype.vcxproj, builds/windows/vc2010/index.html, builds/windows/visualc/freetype.dsp, builds/windows/visualc/freetype.vcproj, builds/windows/visualc/index.html, builds/windows/visualce/freetype.dsp, builds/windows/visualce/freetype.vcproj, builds/windows/visualce/index.html, builds/wince/vc2005-ce/freetype.vcproj, builds/wince/vc2005-ce/index.html, builds/wince/vc2008-ce/freetype.vcproj, builds/wince/vc2008-ce/index.html: s/2.6.1/2.6.2/, s/261/262/. * include/freetype/freetype.h (FREETYPE_PATCH): Set to 2. * builds/unix/configure.raw (version_info): Set to 18:2:12. * CMakeLists.txt (VERSION_PATCH): Set to 2. * docs/CHANGES: Updated. 2015-11-28 Werner Lemberg <wl@gnu.org> Fix C++ compilation. * src/autofit/afloader.c: Include FT_INTERNAL_CALC_H. * src/truetype/ttgload.c (load_truetype_glyph): Pacify compiler. 2015-11-28 Nikolaus Waxweiler <madigens@gmail.com> Change default LCD filter to be normalized and color-balanced. * src/base/ftlcdfil.c (FT_Library_SetLcdFilter): Update `default_filter'. 2015-11-28 Werner Lemberg <wl@gnu.org> [docmaker] Allow references to section names.

This patch fixes weaknesses in function `tt_face_load_font_dir'. - It incorrectly assumed that valid tables are always at the beginning. As a consequence, some valid tables after invalid entries (which are ignored) were never seen. - Duplicate table entries (this is, having the same tag) were not rejected. - The number of valid tables was sometimes too large, leading to access of invalid tables. * src/sfnt/ttload.c (check_table_dir): Add argument to return number of valid tables.

This patch introduces auxiliary code ranges that identify no-base characters; they refer to glyphs of a script that should be hinted without alignments to blue zones (mostly diacritics). It also splits off ranges for fallback scripts that handle subscript and superscript characters not covered by OpenType features. For example, this greatly helps improve the hinting of various phonetic alphabets, which contain a large amount characters that look like superscript glyphs. Finally, code ranges are updated to Unicode 8.0, and enclosed characters are removed in general since they normally look better if they stay unhinted. * src/autofit/afranges.c (af_latn_uniranges): Updated to Unicode 8.0. Split off superscript-like and subscript-like glyphs into... (af_latb_uniranges, af_latp_uniranges): ... these two new arrays.

(SFNT_Interface, FT_DEFINE_SFNT_INTERFACE): New member `get_name'. * src/sfnt/sfdriver.c (sfnt_interface): Updated. * src/sfnt/sfobjs.c (tt_face_get_name): Tag it with `LOCAL_DEF'. * src/sfnt/sfobjs.h: Add prototype for it. 2015-06-30 Werner Lemberg <wl@gnu.org> Fix some clang compiler warnings. * src/base/ftoutln.c (FT_Outline_EmboldenXY), src/cff/cf2intrp.c (cf2_interpT2CharString), src/truetype/ttgload.c (load_truetype_glyph), src/truetype/ttgxvar.c (tt_handle_deltas), src/truetype/ttinterp.c (Ins_INSTCTRL): Fix signedness issues. 2015-06-29 Alexei Podtelezhnikov <apodtele@gmail.com> [truetype] Speed up bytecode interpreter. * src/truetype/ttinterp.c (Normalize): Use `FT_Vector_NormLen'. 2015-06-29 Alexei Podtelezhnikov <apodtele@gmail.com> [base] Speed up emboldening. * src/base/ftoutln.c (FT_Outline_EmboldenXY): Use `FT_Vector_NormLen'. 2015-06-29 Alexei Podtelezhnikov <apodtele@gmail.com> [base] Implement fast vector normalization. The function uses Newton's iterations instead of dividing vector components by its length, which needs a square root. This is, literally, a bit less accurate but a lot faster. * src/base/ftcalc.c (FT_Vector_NormLen): New function. 2015-06-28 Werner Lemberg <wl@gnu.org> * CMakeLists.txt: Always create `ftconfig.h'. For non-UNIX builds, the file stays unmodified. However, it's better to have the main configuration files at the same place regardless of the OS. 2015-06-28 Werner Lemberg <wl@gnu.org> * CMakeLists.txt: Improve MSVC support (#43737). 2015-06-28 Werner Lemberg <wl@gnu.org> [cmake] Check for libraries and create `ftoption.h'. * builds/FindHarfBuzz.cmake: New file, taken from https://trac.webkit.org/browser/trunk/Source/cmake/FindHarfBuzz.cmake * CMakeLists.Txt: Add path to local cmake modules. Find dependencies for zlib, bzip2, libpng, and harfbuzz. Create `ftoption.h' file. Set up include and linker stuff for libraries. 2015-06-28 Werner Lemberg <wl@gnu.org> * CMakeLists.txt: Fix creation of `ftconfig.h'. Check for UNIX header files using `check_include_file'. Set up correct header include directories. 2015-06-28 Werner Lemberg <wl@gnu.org> * CMakeLists.txt: Disallow in-source builds. 2015-06-27 Werner Lemberg <wl@gnu.org> * src/tools/docmaker/utils.py (check_output): Add missing `\n'. 2015-06-26 Werner Lemberg <wl@gnu.org> * CMakeLists.txt: Select platform-dependent `ftdebug.c'. 2015-06-25 Werner Lemberg <wl@gnu.org> * CMakeLists.txt: Use cmake functions for generating `ftconfig.h'. Additionally, do this for UNIX only. 2015-06-25 Werner Lemberg <wl@gnu.org> * CMakeLists.txt (BASE_SRCS): Use `ftbase.c' and `psnames.c'. 2015-06-25 Werner Lemberg <wl@gnu.org> Another adjustment to header locations. This change is a result of a discussion thread on freetype-devel https://lists.nongnu.org/archive/html/freetype-devel/2015-06/msg00041.html Re-introduce the `freetype2' subdirectory for all FreeType header files after installation, and rename the `freetype2' subdirectory in the git repository to `freetype'. * include/freetype2: Renamed to... * include/freetype: This. * CMakeLists.txt (PUBLIC_HEADERS, PUBLIC_CONFIG_HEADERS, PRIVATE_HEADERS): Updated. Update creation of `ftconfig.h'. Install generated `ftconfig.h'. * Jamfile (HDRMACRO, RefDoc), autogen.sh: Updated. * builds/amiga/include/config/ftconfig.h, builds/freetype.mk (PUBLIC_DIR), builds/symbian/bld.inf, builds/toplevel.mk (work), builds/unix/freetype2.in: Updated. * builds/unix/freetype-config.in: Updated. * builds/unix/configure.raw: Don't check for `rmdir'. * builds/unix/unix-def.in (DELDIR): Use `rm -rf', which is portable according to the autoconf info manual. * builds/unix/install.mk (install, uninstall, distclean_project_unix): Update and simplify. * builds/wince/, builds/windows/: Updated. * devel/ft2build.h, include/ft2build.h: Updated. * include/freetype2/config/ftheader.h, include/freetype2/internal/ftserv.h, include/freetype2/internal/internal.h: Update all header file macros. * src/tools/chktrcmp.py (TRACE_DEF_FILES): Updated. * docs/: Updated. 2015-06-24 Alexei Podtelezhnikov <apodtele@gmail.com> src/bdf/bdflib.c (_bdf_parse_start): Disallow 0 bpp. 2015-06-24 Alexei Podtelezhnikov <apodtele@gmail.com> * src/bdf/bdflib.c (_bdf_parse_start): Simplify bpp parsing. 2015-06-23 Werner Lemberg <wl@gnu.org> s/TYPEOF/FT_TYPEOF/ (#45376). * builds/unix/ftconfig.in, builds/vms/ftconfig.in, include/freetype2/config/ftconfig.h, include/freetype2/internal/ftobjs.h, src/autofit/afwarp.h: Do it. 2015-06-22 Werner Lemberg <wl@gnu.org> Fix Savannah bug #45097. We no longer `pollute' the namespace of possible header file names; instead we move `ft2build.h' up by one level so that it gets installed in the default include directory (e.g., /usr/local/include). After this commit, only `ft2build.h' stays in the compiler's include path. No visible changes for the user who follows the standard FreeType header inclusion rules. * include/: Move to ... include/freetype2/: This directory, except `ft2build.h'. CMakeLists.txt (PUBLIC_HEADERS, PUBLIC_CONFIG_HEADERS, PRIVATE_HEADERS), Jamfile (HDRMACRO, RefDoc), autogen.sh: Updated. * builds/amiga/include/config/ftconfig.h, builds/freetype.mk (PUBLIC_DIR), builds/symbian/bld.inf, builds/toplevel.mk (work), builds/unix/install.mk (install, uninstall), builds/unix/freetype2.in: Updated. * builds/unix/freetype-config.in: Updated. Emit -I directory only if it is not `/usr/include'. * builds/wince/, builds/windows/: Updated. * devel/ft2build.h, include/ft2build.h: Updated. * include/freetype2/config/ftheader.h, include/freetype2/internal/ftserv.h, include/freetype2/internal/internal.h: Update all header file macros. * src/tools/chktrcmp.py (TRACE_DEF_FILES): Updated. 2015-06-21 Werner Lemberg <wl@gnu.org> Make Jam support work again. This is just very basic stuff and just a little bit tested on GNU/Linux only. I won't delve into this since I'm not a Jam user. * Jamfile: Call `HDRMACRO' for `ftserv.h' also. (DEFINES): Replace with... (CCFLAGS): ... this. * src/Jamfile: Don't call `HDRMACRO' for `internal.h'; this is already handled in the top-level Jamfile. * src/autofit/Jamfile (DEFINES): Replace with... (CCFLAGS): ... this. (_sources): Add missing files. * src/cache/Jamfile: Don't call `HDRMACRO' for `ftcache.h'; it no longer contains macro header definitions. * src/base/Jamfile, src/cff/Jamfile, src/sfnt/Jamfile, src/truetype/Jamfile (_sources): Add missing files. 2015-06-16 Werner Lemberg <wl@gnu.org> Fix Savannah bug #45326. * src/sfnt/sfntpic.h (SFNT_SERVICES_GET): Remove duplicate definitions. 2015-06-07 Werner Lemberg <wl@gnu.org> * Version 2.6 released. ======================= Tag sources with `VER-2-6'. * docs/VERSION.DLL: Update documentation and bump version number to 2.6. * README, Jamfile (RefDoc), builds/windows/vc2005/freetype.vcproj, builds/windows/vc2005/index.html, builds/windows/vc2008/freetype.vcproj, builds/windows/vc2008/index.html, builds/windows/vc2010/freetype.vcxproj, builds/windows/vc2010/index.html, builds/windows/visualc/freetype.dsp, builds/windows/visualc/freetype.vcproj, builds/windows/visualc/index.html, builds/windows/visualce/freetype.dsp, builds/windows/visualce/freetype.vcproj, builds/windows/visualce/index.html, builds/wince/vc2005-ce/freetype.vcproj, builds/wince/vc2005-ce/index.html, builds/wince/vc2008-ce/freetype.vcproj, builds/wince/vc2008-ce/index.html: s/2.5.5/2.6/, s/255/26/. * include/freetype/freetype.h (FREETYPE_MINOR): Set to 6. (FREETYPE_PATCH): Set to 0. * builds/unix/configure.raw (version_info): Set to 18:0:12. * CMakeLists.txt (VERSION_MINOR): Set to 6. (VERSION_PATCH): Set to 0. * src/autofit/afmodule.c [!FT_MAKE_OPTION_SINGLE_OBJECT]: Add declarations for dumping functions. * src/truetype/ttinterp.c (TT_New_Context): Pacify compiler. * builds/toplevel.mk: Use `freetype.mk's code to compute the version string. Don't include a zero patch level in version string. * builds/freetype.mk: Remove code for computing the version string. 2015-06-06 Ashish Azad <ashish.azad@samsung.com> Fix Savannah bug #45260. * src/pfr/pfrdrivr.c (pfr_get_kerning): Fix typo. 2015-06-03 Werner Lemberg <wl@gnu.org> [truetype] Fix memory leak. Problem reported by Grissiom <chaos.proton@gmail.com>; in https://lists.nongnu.org/archive/html/freetype/2015-05/msg00013.html there is an example code to trigger the bug. * src/truetype/ttobjs.c (tt_size_init_bytecode): Free old `size' data before allocating again. Bug most probably introduced four years ago in version 2.4.3. 2015-06-02 Werner Lemberg <wl@gnu.org> [raster] Add more tracing. * src/raster/ftraster.c (FT_TRACE7) [_STANDALONE_]: Define. (Vertical_Sweep_Span, Vertical_Sweep_Drop, Horizontal_Sweep_Span, Horizontal_Sweep_Drop, Render_Glyph): Add tracing calls. 2015-06-01 Werner Lemberg <wl@gnu.org> [truetype] While tracing opcodes, show code position and stack. * src/truetype/ttinterp.c: Change all existing TRACE7 calls to TRACE6. (opcode_name): Add string lengths. (TT_RunIns): Implement display of code position and stack. 2015-05-31 Werner Lemberg <wl@gnu.org> [truetype] In GX, make private point numbers work correctly. This is completely missing in Apple's documentation: If a `gvar' tuple uses private point numbers (this is, deltas are specified for some points only), the uncovered points must be interpolated for this tuple similar to the IUP bytecode instruction. Examples that need this functionality are glyphs `Oslash' and `Q' in Skia.ttf. * src/truetype/ttgxvar.c (tt_delta_shift, tt_delta_interpolate, tt_handle_deltas): New functions. (TT_Vary_Get_Glyph_Deltas): Renamed to... (TT_Vary_Apply_Glyph_Deltas): ... this; it directly processes the points and does no longer return an array of deltas. Add tracing information. Call `tt_handle_deltas' to interpolate missing deltas. Also fix a minor memory leak in case of error. * src/truetype/ttgxvar.h: Updated. * src/truetype/ttgload.c (TT_Process_Simple_Glyph, load_truetype_glyph): Updated. 2015-05-31 Werner Lemberg <wl@gnu.org> [truetype] In GX, make intermediate tuplets work at extrema. * src/truetype/ttgxvar.c (ft_var_apply_tuple): Fix range condition. 2015-05-31 Werner Lemberg <wl@gnu.org> [truetype] Add tracing information to GX code. * src/truetype/ttgxvar.c (ft_var_load_avar, ft_var_load_gvar, ft_var_apply_tuple, TT_Get_MM_Var, TT_Set_MM_Blend, TT_Set_Var_Design, tt_face_vary_cvt): Do it. 2015-05-28 Werner Lemberg <wl@gnu.org> * src/tools/apinames.c (names_dump): Fix invalid reference. Problem reported by Guzman Mosqueda, Jose R <jose.r.guzman.mosqueda@intel.com>. 2015-05-24 Werner Lemberg <wl@gnu.org> [truetype] Fix commit from 2015-05-22. * src/truetype/ttgload.c, src/truetype/ttinterp.c: Guard new code with `TT_CONFIG_OPTION_SUBPIXEL_HINTING'. Problem reported by Nikolaus Waxweiler <madigens@gmail.com>. 2015-05-23 Werner Lemberg <wl@gnu.org> [truetype] Fix return values of GETINFO bytecode instruction. * src/truetype/ttinterp.h (TT_ExecContextRec): New fields `vertical_lcd' and `gray_cleartype'. * src/truetype/ttgload.c (tt_loader_init): Initialize new fields. Change `symmetrical smoothing' to TRUE, since FreeType produces exactly this. * src/truetype/ttinterp.c (Ins_GETINFO): Fix selector/return bit values for symmetrical smoothing, namely 11/18. Handle bits for vertical LCD subpixels (8/15) and Gray ClearType (12/19). 2015-05-23 Werner Lemberg <wl@gnu.org> [truetype] Minor. * src/truetype/ttinterp.h (TT_ExecContext): s/subpixel/subpixel_hinting. * src/truetype/ttgload.c, src/truetype/ttgload.h: Updated. 2015-05-22 Werner Lemberg <wl@gnu.org> [truetype] Support selector index 3 of the INSTCTRL instruction. This flag activates `native ClearType hinting', disabling backward compatibility mode as described in Greg Hitchcocks whitepaper. In other words, it enables unrestricted functionality of all TrueType instructions in ClearType. * src/truetype/ttgload.c (tt_get_metrics): Call `sph_set_tweaks' unconditionally. (tt_loader_init): Unset `ignore_x_mode' flag if bit 2 of `GS.instruct_control' is active. * src/truetype/ttinterp.c (Ins_INSTCTRL): Handle selector index 3. (Ins_GETINFO): Updated. * docs/CHANGES: Document it. 2015-05-20 Werner Lemberg <wl@gnu.org> [truetype] Minor. * src/truetype/ttinterp.h (SetSuperRound): Fix type of `GridPeriod' argument. 2015-05-17 Werner Lemberg <wl@gnu.org> [truetype] Fix loading of composite glyphs. * src/truetype/ttgload.c (TT_Load_Composite_Glyph): If the ARGS_ARE_XY_VALUES flag is not set, handle argument values as unsigned. I trust `ttx' (which has exactly such code) that it does the right thing here... The reason that noone has ever noticed this bug is probably the fact that point-aligned subglyphs are rare, as are subglyphs with a number of points in the range [128;255], which is quite large (or even in the range [32768;65535], which is extremely unlikely). 2015-05-12 Chris Liddell <chris.liddell@artifex.com> [cff] Make the `curveto' operators more tolerant. src/cff/cf2intrp.c (cf2_interpT2CharString): The opcodes `vvcurveto', `hhcurveto', `vhcurveto', and `hvcurveto' all iterate, pulling values off the stack until the stack is exhausted. Implicitly the stack must be a multiple (or for subtly different behaviour) a multiple plus a specific number of extra values deep. If that's not the case, enforce it (as the old code did). 2015-05-12 Chris Liddell <chris.liddell@artifex.com> [cff] fix incremental interface with new cff code. * src/cff/cf2ft.c (cf2_getSeacComponent): When using the incremental interface to retrieve glyph data for a SEAC, it be left to the incremental interface callback to apply the encoding to raw character index (as it was in the previous code). 2015-04-29 Alexei Podtelezhnikov <apodtele@gmail.com> [autofit] Speed up IUP. * src/autofit/afhints.c (af_iup_interp): Separate trivial snapping to the same position from true interpolation, use `scale' to reduce divisions. 2015-04-28 Werner Lemberg <wl@gnu.org> [cff] Use `name' table for PS name if we have a SFNT-CFF. This follows the OpenType 1.7 specification. See https://tug.org/pipermail/tex-live/2015-April/036634.html for a discussion. * src/cff/cffdrivr.c (cff_get_ps_name): Use the `sfnt' service if we have an SFNT. 2015-04-27 Alexei Podtelezhnikov <apodtele@gmail.com> [truetype] Speed up IUP. * src/truetype/ttinterp.c (_iup_worker_interpolate): Separate trivial snapping to the same position from true interpolation. 2015-04-21 Werner Lemberg <wl@gnu.org> [autofit] By default, enable warping code but switch off warping. Suggested by Behdad. * include/config/ftoption.h: Define AF_CONFIG_OPTION_USE_WARPER. * src/autofit/afmodule.c (af_autofitter_init): Initialize `warping' with `false'. 2015-04-21 Werner Lemberg <wl@gnu.org> * docs/CHANGES: Updated. 2015-04-21 Werner Lemberg <wl@gnu.org> [autofit] Introduce `warping' property. This code replaces the debugging hook from the previous commit with a better, more generic solution. * include/ftautoh.h: Document it. * src/autofit/afmodule.h (AF_ModuleRec) [AF_CONFIG_OPTION_USE_WARPER]: Add `warping' field. * src/autofit/afmodule.c (_af_debug_disable_warper): Remove. (af_property_set, af_property_get, af_autofitter_init) [AF_CONFIG_OPTION_USE_WARPER]: Handle `warping' option. * src/autofit/afhints.h (AF_HINTS_DO_WARP): Remove use of the no longer existing `_af_debug_disable_warper'. * src/autofit/afcjk.c (af_cjk_hints_init), src/autofit/aflatin.c (af_latin_hints_init), src/autofit/aflatin2.c (af_latin2_hints_init) [AF_CONFIG_OPTION_USE_WARPER]: Add `AF_SCALER_FLAG_NO_WARPER' to the scaler flags if warping is off. * src/autofit/aftypes.h: Updated. 2015-04-16 Werner Lemberg <wl@gnu.org> [autofit] Add debugging hook to disable warper. * src/autofit/afmodule.c (_af_debug_disable_warper) [FT_DEBUG_AUTOFIT]: New global variable. * src/autofit/aftypes.h: Updated. (AF_SCALER_FLAG_NO_WARPER): New macro (not actively used yet). * src/autofit/afhints.h (AF_HINTS_DO_WARP): New macro. * src/autofit/aflatin.c (af_latin_hints_apply) [AF_CONFIG_OPTION_USE_WARPER]: Use `AF_HINTS_DO_WARP' to control use of warper. * src/autofit/afcjk.c (af_cjk_hints_init, af_cjk_hints_apply) [AF_CONFIG_OPTION_USE_WARPER]: Synchronize with `aflatin.c'. * src/autofit/aflatin2.c (af_latin2_hints_apply) [AF_CONFIG_OPTION_USE_WARPER]: Synchronize with `aflatin.c'. 2015-04-10 Werner Lemberg <wl@gnu.org> [cff] Update advance width handling to OpenType 1.7. Problem reported by Behdad. * src/cff/cffdrivr.c (cff_get_advances): Handle SFNT case separately. * src/cff/cffgload.c (cff_slot_load): Use advance width and side bearing values from `hmtx' table if present. 2015-04-03 Alexei Podtelezhnikov <apodtele@gmail.com> * src/autofit/afhints.c (af_glyph_hints_reload): Use do-while loop. 2015-04-02 Alexei Podtelezhnikov <apodtele@gmail.com> * src/autofit/aflatin.c (af_latin_hint_edges): Reduce logic. 2015-04-01 Alexei Podtelezhnikov <apodtele@gmail.com> [autofit] Finish the thought. * src/autofit/afhints.c (af_direction_compute): make sure the long arm is never negative so that its `FT_ABS' is not necessary. 2015-04-01 Werner Lemberg <wl@gnu.org> [autofit] Call dumper functions for tracing. * src/autofit/afcjk.c (af_cjk_hints_apply): Remove dead code. * src/autofit/afhints.c (af_glyph_hints_dump_points): Minor improvement. * src/autofit/afmodule.c (af_autofitter_load_glyph): Implement it. 2015-04-01 Werner Lemberg <wl@gnu.org> [autofit] Make debugging stuff work again. The interface to ftgrid was broken in the series of commits starting with [autofit] Allocate AF_Loader on the stack instead of AF_Module. from 2015-01-14. * src/autofit/afmodule.c (_af_debug_hints_rec) [FT_DEBUG_AUTOFIT]: Use a global AF_GlyphHintsRec object for debugging. (af_autofitter_done, af_autofitter_load_glyph): Updated. * src/autofit/afloader.c (af_loader_init, af_loader_done): Updated. 2015-04-01 Werner Lemberg <wl@gnu.org> * src/autofit/afhints.c (af_glyph_hints_done): Fix minor thinko. 2015-03-29 Werner Lemberg <wl@gnu.org> [cff] Fix Savannah bug #44629. * src/cff/cf2font.h (CF2_MAX_SUBR), src/cff/cffgload.h (CFF_MAX_SUBRS_CALLS): Set to 16. 2015-03-29 Werner Lemberg <wl@gnu.org> [type1, truetype] Make the MM API more flexible w.r.t. `num_coords'. This commit allows `num_coords' to be larger or smaller than the number of available axes while selecting a design instance, either ignoring excess data or using defaults if data is missing. * src/truetype/ttgxvar.c (TT_Set_MM_Blend, TT_Set_Var_Design): Implement it. * src/type1/t1load.c (T1_Set_MM_Blend, T1_Set_MM_Design, T1_Set_Var_Design): Ditto. 2015-03-29 Werner Lemberg <wl@gnu.org> [type1] Minor. * src/type1/t1load.c (T1_Set_MM_Blend, T1_Set_MM_Design): Use FT_THROW. (T1_Set_Var_Design): Use T1_MAX_MM_AXIS and FT_THROW. 2015-03-27 Werner Lemberg <wl@gnu.org> [cff] Trace charstring nesting levels. * src/cff/cf2intrp.c (cf2_interpT2CharString) <cf2_cmdCALLGSUBR, cf2_cmdCALLSUBR, cf2_cmdRETURN>: Implement it. * src/cff/cffgload.c (cff_decoder_parse_charstrings) <cff_op_callsubr, cff_op_callgsubr, cff_op_return>: Ditto. 2015-03-21 Alexei Podtelezhnikov <apodtele@gmail.com> [base] Optimize `FT_Angle_Diff'. Under normal circumstances we are usually close to the desired range of angle values, so that the remainder is not really necessary. * src/base/fttrigon.c (FT_Angle_Diff): Use loops instead of remainder. * src/autofit/aftypes.h (AF_ANGLE_DIFF): Ditto in the unused macro. 2015-03-21 Werner Lemberg <wl@gnu.org> [truetype] Improve `gvar' handling. * src/truetype/ttgxvar.c (ft_var_readpackedpoints): Correctly handle single-element runs. Cf. glyph `Q' in Skia.ttf with weights larger than the default. 2015-03-20 Alexei Podtelezhnikov <apodtele@gmail.com> * src/base/fttrigon.c (FT_Vector_Rotate): Minor refactoring. 2015-03-17 Alexei Podtelezhnikov <apodtele@gmail.com> Fix Savannah bug #44412 (part 2). * src/base/fttrigon.c (FT_Sin, FT_Cos, FT_Tan): Call `FT_Vector_Unit'. 2015-03-11 Werner Lemberg <wl@gnu.org> [autofit] Add support for Arabic script. Thanks to Titus Nemeth <tn@tntypography.eu> for guidance! * src/autofit/afblue.dat: Add blue zone data for Arabic. * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated. * src/autofit/afscript.h: Add Arabic standard characters. * src/autofit/afranges.c: Add Arabic data. * src/autofit/afstyles.h: Add Arabic data. * docs/CHANGES: Document it. 2015-03-11 Werner Lemberg <wl@gnu.org> Rename `svxf86nm.h' to `svfntfmt.h'; update related symbols. * include/internal/ftserv.h (FT_SERVICE_XFREE86_NAME_H): Renamed to...

While this doesn't show up with FreeType, exactly the same code leaks with ttfautohint's modified auto-hinter code (which gets used in a slightly different way).

Problem reported by Markus Trippelsdorf <markus@trippelsdorf.de>. * src/raster/ftraster.c (ft_black_render): Handle `FT_RASTER_FLAG_AA'. * src/raster/ftrend1.c (ft_raster1_render): Remove gray AA mode remnants. 2015-01-18 Werner Lemberg <wl@gnu.org> * src/base/ftobjs.c (FT_New_Library): Fix compiler warning. 2015-01-18 Chris Liddell <chris.liddell@artifex.com> [raster] Fix Savannah bug #44022. Add fallback for glyphs with degenerate bounding boxes. If a glyph has only one very narrow feature, the bbox can end up with either the width or height of the bbox being 0, in which case no raster memory is allocated and no attempt is made to render the glyph. This is less than ideal when the drop-out compensation in the rendering code would actually result in the glyph being rendered. This problem can be observed with the `I' glyph (gid 47) in the Autodesk RomanS TrueType font. * src/raster/ftrend1.c (ft_raster1_render): Add a fallback if either dimension is zero to explicitly round up/down (instead of simply round). 2015-01-17 Werner Lemberg <wl@gnu.org> Add some tools to handle yearly copyright notice updates.

(AF_GlyphHintsRec): Add two arrays for contours and points. * src/autofit/afhints.c (af_glyph_hints_init, af_glyph_hints_done): Updated. (af_glyph_hints_reload): Only allocate data if number of contours or points exceeds given threshold values. 2015-01-14 Behdad Esfahbod <behdad@behdad.org> [autofit] Allocate hints object on the stack. This avoids one malloc per load. * src/autofit/afloader.h (AF_LoaderRec): Change type of `hints' to `AF_GlyphHints'. Update prototype. * src/autofit/afloader.c (af_loader_init): Use `AF_GlyphHints' parameter instead of `FT_Memory'. (af_loader_done): Directly reset `load_hints'. (af_loader_load_g): Updated. * src/autofit/afmodule.c (af_autofitter_load_glyph): Use local `hints' object. 2015-01-14 Behdad Esfahbod <behdad@behdad.org> [autofit] Reuse slot glyph loader. No need to create a new glyph loader; we can reuse the one from `slot->internal->loader'. It's hard to tell why it was written that way originally, but new code looks sound and correct to me, and avoids lots of allocations. * src/autofit/afloader.c (af_loader_init): Change return type to `void'. Don't call `FT_GlyphLoader_New'. (af_loader_reset): Don't call `FT_GlyphLoader_Rewind'. (af_loader_load_g): Update code to use `internal->loader', which doesn't need copying of data. * src/autofit/afloader.h (AF_LoaderRec): Remove `gloader' member. Update prototype. * src/autofit/afmodule.c (af_autofitter_load_glyph): Updated. 2015-01-14 Behdad Esfahbod <behdad@behdad.org> [autofit] Remove (unused) support for composite glyphs. We never have to deal with composite glyphs in the autohinter, as those will be loaded into FORMAT_OUTLINE by the recursed `FT_Load_Glyph' function. In the rare cases that FT_LOAD_NO_RECURSE is set, it will imply FT_LOAD_NO_SCALE as per `FT_Load_Glyph', which then implies FT_LOAD_NO_HINTING: /* resolve load flags dependencies / if ( load_flags & FT_LOAD_NO_RECURSE ) load_flags \|= FT_LOAD_NO_SCALE \| FT_LOAD_IGNORE_TRANSFORM; if ( load_flags & FT_LOAD_NO_SCALE ) { load_flags \|= FT_LOAD_NO_HINTING \| FT_LOAD_NO_BITMAP; load_flags &= ~FT_LOAD_RENDER; } and as such the auto-hinter is never called. Thus, the recursion in `af_loader_load_g' never actually happens. So remove the depth counter as well. src/autofit/afloader.c (af_loader_load_g): Remove `depth' parameter. <FT_GLYPH_FORMAT_COMPOSITE>: Remove associated code. (af_loader_load_glyph): Updated. 2015-01-14 Behdad Esfahbod <behdad@behdad.org> [raster] Fix uninitialized memory access. Apparently `ras.cProfile' might be uninitialized. This will be the case if `ras.top == ras.cProfile->offset', as can be seen in `End_Profile'. The overshoot code introduced in a change `Fix B/W rasterization of subglyphs with different drop-out modes.' (from 2009-06-18) violated this, accessing `ras.cProfile->flags' unconditionally just before calling `End_Profile' (which then detected that `cProfile' is uninitialized and didn't touch it). This was harmless, and was not detected by valgrind before because the objects were allocated on the `raster_pool', which was always initialized. With recent change to allocate raster buffers on the stack, valgrind now reported this invalid access. * src/raster/ftraster.c (Convert_Glyph): Don't access an uninitialized `cProfile'. 2015-01-14 Behdad Esfahbod <behdad@behdad.org> [smooth] Fix uninitialized memory access. Looks like `ras.span_y' could always be used without initialization. This was never detected by valgrind before because the library-wide `raster_pool' was used for the worker object and `raster_pool' was originally zero'ed. But subsequent reuses of it were using `span_y' uninitialized. With the recent change to not use `render_pool' and allocate worker and buffer on the stack, valgrind now detects this uninitialized access. * src/smooth/ftgrays.c (gray_raster_render): Initialize `ras.span_y'. 2015-01-14 Behdad Esfahbod <behdad@behdad.org> [base] Don't initialize unused `driver->glyph_loader'. * src/base/ftobjs.c (Destroy_Driver): Don't call `FT_GlyphLoader_Done'. (FT_Add_Module): Don't call `FT_GlyphLoader_New'. 2015-01-14 Behdad Esfahbod <behdad@behdad.org> [base] Don't allocate `library->raster_pool' anymore. It's unused after the following commits: [raster] Allocate render pool for mono rasterizer on the stack. [raster] Remove 5-level gray AA mode from monochrome rasterizer. The value of FT_RENDER_POOL_SIZE still serves the purpose it used to serve, which is, to adjust the pool size. But the pool is now allocated on the stack on demand. * src/base/ftobjs.c (FT_New_Library, FT_Done_Library): Implement. 2015-01-14 Behdad Esfahbod <behdad@behdad.org> [base] Do not reorder library->renderers upon use. Instead of keeping `library->renderers' in a MRU order, just leave it as-is. The MRU machinery wasn't thread-safe. With this patch, rasterizing glyphs from different faces from different threads doesn't fail choosing rasterizer (FT_Err_Cannot_Render_Glyph). Easiest to see that crash was to add a `printf' (or otherwise let thread yield in FT_Throw with debugging enabled). * src/base/ftobjs.c (FT_Render_Glyph_Internal), src/base/ftoutln.c (FT_Outline_Render): Don't call `FT_Set_Renderer'. 2015-01-14 Behdad Esfahbod <behdad@behdad.org> [raster] Allocate render pool for mono rasterizer on the stack. Instead of using the `render_pool' member of `FT_Library' that is provided down to the rasterizer, completely ignore that and allocate needed objects on the stack instead. With this patch, rasterizing glyphs from different faces from different threads doesn't crash in the monochrome rasterizer. * src/raster/ftraster.c (black_TRaster): Remove `buffer', `buffer_size', and `worker' members. (ft_black_render): Create `buffer' locally. (ft_black_reset): Updated. 2015-01-14 Behdad Esfahbod <behdad@behdad.org> [raster] Remove 5-level gray AA mode from monochrome rasterizer. It was off by default and couldn't be turned on at runtime. And the smooth rasterizer superseded it over ten years ago. No point in keeping. Comments suggested that it was there for compatibility with FreeType 1. 550 lines down. * src/raster/ftraster.c (FT_RASTER_OPTION_ANTI_ALIASING, RASTER_GRAY_LINES): Remove macros and all associated code. (black_TWorker): Remove `gray_min_x' and `gray_max_x'. (black_TRaster): Remove `grays' and `gray_width'. (Vertical_Sweep_Init, Vertical_Sweep_Span, Vertical_Sweep_Drop, ft_black_render): Updated. * src/raster/ftrend1.c (ft_raster1_render): Simplify code. (ft_raster5_renderer_class): Removed. 2015-01-14 Behdad Esfahbod <behdad@behdad.org> [smooth] Allocate render pool for smooth rasterizer on the stack. Instead of using the `render_pool' member of `FT_Library' that is provided down to the rasterizer, completely ignore that and allocate needed objects on the stack instead. With this patch, rasterizing glyphs from different faces from different threads doesn't crash in the smooth rasterizer. Bugs: https://bugzilla.redhat.com/show_bug.cgi?id=678397 https://bugzilla.redhat.com/show_bug.cgi?id=1004315 https://bugzilla.redhat.com/show_bug.cgi?id=1165471 https://bugs.freedesktop.org/show_bug.cgi?id=69034 * src/smooth/ftgrays.c (gray_TRaster): Remove `buffer', `buffer_size', `band_size', and `worker' members. (gray_raster_render): Create `buffer', `buffer_size', and `band_size' locally. (gray_raster_reset): Updated. 2015-01-14 Behdad Esfahbod <behdad@behdad.org> [truetype] Allocate TT_ExecContext in TT_Size instead of TT_Driver. Previously the code had stipulation for using a per-TT_Size exec context if `size->debug' was true. But there was no way that `size->debug' could ever be true. As such, the code was always using the singleton `TT_ExecContext' that was stored in `TT_Driver'. This was, clearly, not threadsafe. With this patch, loading glyphs from different faces from different threads doesn't crash in the bytecode loader code. * src/truetype/ttobjs.h (TT_SizeRec): Remove `debug' member. (TT_DriverRec): Remove `context' member. * src/truetype/ttobjs.c (tt_size_run_fpgm, tt_size_run_prep): Remove `TT_ExecContext' code related to a global `TT_Driver' object. (tt_driver_done): Don't remove `TT_ExecContext' object here but ... (tt_size_done_bytecode): ... here. (tt_driver_init): Don't create `TT_ExecContext' object here but ... (tt_size_init_bytecode): ... here, only on demand. * src/truetype/ttinterp.c (TT_Run_Context): Remove defunct debug code. (TT_New_Context): Remove `TT_ExecContext' code related to a global `TT_Driver' object. * src/truetype/ttinterp.h: Updated. * src/truetype/ttgload.c (TT_Hint_Glyph, tt_loader_init): Updated. 2015-01-14 Behdad Esfahbod <behdad@behdad.org> [autofit] Allocate AF_Loader on the stack instead of AF_Module. Stop sharing a global `AF_Loader'. Allocate one on the stack during glyph load. Right now this results in about 25% slowdown, to be fixed in a following commit. With this patch loading glyphs from different faces from different threads doesn't immediately crash in the autohinting loader code. Bugs: https://bugzilla.redhat.com/show_bug.cgi?id=1164941 * src/autofit/afloader.c (af_loader_init): Pass `AF_Loader' and `FT_Memory' instead of `AF_Module' as arguments. (af_loader_reset, af_loader_load_glyph): Also pass `loader' as argument. (af_loader_done): Use `AF_Loader' instead of `AF_Module' as argument. * src/autofit/afmodule.c (af_autofitter_init): Don't call `af_loader_init'. (af_autofitter_done): Don't call `af_loader_done'. (af_autofitter_load_glyph): Use a local `AF_Loader' object. * src/autofit/afloader.h: Include `afmodule.h'. Update prototypes. Move typedef for `AF_Module' to... * src/autofit/afmodule.h: ... this place. No longer include `afloader.h'. 2015-01-14 Behdad Esfahbod <behdad@behdad.org> * src/type42/t42objs.h (T42_DriverRec): Remove unused member. 2015-01-12 Werner Lemberg <wl@gnu.org> Fix Savannah bug #43976. Assure that FreeType's internal include directories are found before `CPPFLAGS' (which might be set by the user in the environment), and `CPPFLAGS' before `CFLAGS'. * builds/freetype.mk (FT_CFLAGS): Don't add `INCLUDE_FLAGS'. (FT_COMPILE): Make this a special variable for compiling only the files handled in `freetype.mk'. (.c.$O): Removed, unused. * src//rules.mk (_COMPILE): Fix order of include directories. 2015-01-11 Werner Lemberg <wl@gnu.org> [truetype] Prettifying. * src/truetype/ttinterp.c (project, dualproj, fast_project, fast_dualproj): Rename to... (PROJECT, DUALPROJ, FAST_PROJECT, FAST_DUALPROJ): ... this. 2015-01-11 Werner Lemberg <wl@gnu.org> * src/truetype/ttinterp.c (Ins_JROT, Ins_JROF): Simplify. Based on a patch from Behdad. 2015-01-11 Werner Lemberg <wl@gnu.org> * src/truetype/ttinterp.c (Ins_SxVTL): Simplify function call. 2015-01-11 Werner Lemberg <wl@gnu.org> * src/truetype/ttinterp.c (Normalize): Remove unused argument. 2015-01-11 Werner Lemberg <wl@gnu.org> [truetype] More macro expansions. * src/truetype/ttinterp.c (FT_UNUSED_EXEC): Remove macro by expansion. 2015-01-11 Werner Lemberg <wl@gnu.org> [truetype] More macro expansions. * src/truetype/ttinterp.c (INS_ARG): Remove macro by expansion, adjusting function calls where necessary. (FT_UNUSED_ARG): Removed, no longer needed. 2015-01-10 Werner Lemberg <wl@gnu.org> [truetype] More macro expansions. Based on a patch from Behdad. * src/truetype/ttinterp.c (DO_): Expand macros into corresponding `Ins_' functions. (TT_RunIns): Replace `DO_' macros with `Ins_' function calls. (ARRAY_BOUND_ERROR): Remove second definition, which is no longer needed. (Ins_SVTCA, Ins_SPVTCA, Ins_SFVTCA): Replaced with... (Ins_SxyTCA): New function. 2015-01-10 Werner Lemberg <wl@gnu.org> [truetype] Remove TT_CONFIG_OPTION_INTERPRETER_SWITCH. Behdad suggested this code simplification, and nobody objected... * include/config/ftoption.h, devel/ftoption.h (TT_CONFIG_OPTION_INTERPRETER_SWITCH): Remove. * src/truetype/ttinterp.c [TT_CONFIG_OPTION_INTERPRETER_SWITCH]: Remove related code. (ARRAY_BOUND_ERROR): Use do-while loop. 2015-01-10 Werner Lemberg <wl@gnu.org> [truetype] More macro expansions. * src/truetype/ttinterp.c, src/truetype/ttinterp.h (EXEC_ARG_, EXEC_ARG): Remove by replacing with expansion. 2015-01-10 Werner Lemberg <wl@gnu.org> [truetype] More macro expansions.

(Random): Implement and use a 32bit `xorshift' algorithm. 2016-12-30 Werner Lemberg <wl@gnu.org> [ftfuzzer] Restrict number of tested bitmap strikes. Malformed fonts often have large values for the number of bitmap strikes, and FreeType doesn't check the validity of all bitmap strikes in advance. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=353 * src/tools/ftfuzzer/ftfuzzer.cc: Include `stdlib.h' for `rand'. (Random): Small class to provide n randomly selected numbers (without repetition) out of the value set [1,N]. (LLVMFuzzerTestOneInput): Use it to test only up to 10 bitmap strikes. 2016-12-29 Werner Lemberg <wl@gnu.org> [truetype] Variation font API stability issues. Make some functions work before a call to `TT_Set_MM_Blend'. * src/truetype/ttgxvar.c (tt_hadvance_adjust): Exit immediately if we don't blend. (TT_Get_MM_Blend, TT_Get_Var_Design): Return default values if we don't blend. 2016-12-29 Werner Lemberg <wl@gnu.org> * src/truetype/ttgxvar.c (TT_Get_MM_Var): Check axis data.

Fix suggested by Kostya; reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=345 * src/pcf/pcfread.c (pcf_read_TOC): Limit number of TOC entries to 1024. 2016-12-28 Werner Lemberg <wl@gnu.org> [psnames] Only declare, not define, data in `pstables.h' (#49949). Pdfium includes `pstables.h' a second time; moving the definition from `pstables.h' to `psmodule.c' saves more than 60kByte data segment space for this case. * src/tools/glnames.py (StringTable::dump, StringTable::dump_sublist, dump_encoding, dump_array): Emit additional code to only define tables if `DEFINE_PS_TABLES' is set. * src/psnames/pstables.h: Regenerated. * src/psnames/psmodule.c (DEFINE_PS_TABLES): Define. 2016-12-28 Werner Lemberg <wl@gnu.org> [cff] Catch `blend' op in non-variant fonts.

This trivial fix allows us to accept more fonts. Problem reported by 張俊芝 <418092625@qq.com>. 2016-12-24 Werner Lemberg <wl@gnu.org> * src/sfnt/sfobjs.c (sfnt_init_face): Fix tracing. 2016-12-22 Werner Lemberg <wl@gnu.org> * CMakeLists.txt: Make it work with cmake 2.8.11.2 (#49909). 2016-12-22 Werner Lemberg <wl@gnu.org> Ensure used preprocessor symbols are defined (#49790). * builds/unix/ftconfig.in, builds/vms/ftconfig.h, include/freetype/config/ftconfig.h: Check `__GNUC__', `__IBMC__', and `__SUNPRO_C' correctly. 2016-12-22 Werner Lemberg <wl@gnu.org> * src/base/ftrfork.c (FT_Raccess_Get_DataOffsets): Check `count'. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=308 2016-12-22 Werner Lemberg <wl@gnu.org> [cff] Protect against invalid `vsindex' and `blend' values. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=305 * src/cff/cf2intrp.c (cf2_interpT2CharString) <cf2_cmdVSINDEX, cf2_cmdBLEND>: Implement it. 2016-12-22 Werner Lemberg <wl@gnu.org> [ftfuzzer] Always use Adobe CFF engine. * src/tools/ftfuzzer/ftfuzzer.cc (FT_Global::FT_Global): Implement it. 2016-12-21 Werner Lemberg <wl@gnu.org> * src/truetype/ttgxvar.c (TT_Vary_Apply_Glyph_Deltas): Thinko. I should really stop coding late in the evening... Thanks again to Ben for checking. 2016-12-21 Werner Lemberg <wl@gnu.org> [autofit] Support variation fonts. (This ChangeLog entry was added later on.) * src/autofit/afglobal.c (af_face_globals_free): Remove useless code. * src/base/ftmm.c (FT_Set_MM_Design_Coordinates, * FT_Set_Var_Design_Coordinates, FT_Set_MM_Blend_Coordinates, FT_Set_Var_Blend_Coordinates): Finalize auto-hinter data to enforce recomputation. Note that this is a brute-force method which should be improved. 2016-12-21 Werner Lemberg <wl@gnu.org> * src/truetype/ttgxvar.c (TT_Vary_Apply_Glyph_Deltas): Thinko. Don't apply deltas twice for non-phantom points. Spotted by Ben Wagner. 2016-12-21 Werner Lemberg <wl@gnu.org> [cff, truetype] Another try for #49829. * src/cff/cffdrivr.c: Don't include `FT_SERVICE_METRICS_VARIATIONS_H'.

We use https://github.com/kreativekorp/ksfl/wiki/Macintosh-Resource-File-Format and https://developer.apple.com/legacy/library/documentation/mac/pdf/MoreMacintoshToolbox.pdf#page=151 as references. * include/freetype/internal/ftrfork.h (FT_RFork_Ref): Use FT_Short for `res_id'. * src/base/ftrfork.c (FT_Raccess_Get_HeaderInfo): Extract map length and use it to improve sanity checks. Follow the specification more closely;in particular, all data types are signed, not unsigned. (FT_Raccess_Get_DataOffsets): Follow the specification more closely; in particular, all data types are signed, not unsigned. Add some sanity checks. 2016-12-20 Werner Lemberg <wl@gnu.org> [truetype] Improve logic for getting fast advance widths. * src/cff/cffdrivr.c (cff_get_advances), src/truetype/ttdriver.c (tt_get_advances): Use `is_default_instance' for test; this gets recomputed after changing blend coordinates. 2016-12-20 Ben Wagner <bungeman@google.com> Werner Lemberg <wl@gnu.org> [truetype] Fix linear metrics of GX variation fonts (#49829). When asking for an unhinted non-default variations, `linearVertAdvance' is currently the value from the `hmtx' table instead of the actual value after applying the variation. `HVAR' support fixes this, but fonts will exist without that table and will need sane fallback. Problem also reported as https://bugs.chromium.org/p/skia/issues/detail?id=5917 * src/truetype/ttgload.c (TT_Process_Simple_Glyph, load_truetype_glyph): Implement linear advance adjustments if `HVAR' or `VVAR' tables are missing. 2016-12-20 Werner Lemberg <wl@gnu.org> [cff, truetype] Fast advance width retrieval for fonts with HVAR. Everything is guarded with TT_CONFIG_OPTION_GX_VAR_SUPPORT. * src/base/ftadvanc.c (LOAD_ADVANCE_FAST_CHECK): Don't handle MM. * src/cff/cffdrivr.c: Include FT_SERVICE_METRICS_VARIATIONS_H. (cff_get_advances): Test for HVAR and VVAR. * src/truetype/ttdriver.c (tt_get_advances): Test for HVAR and VVAR. 2016-12-18 Werner Lemberg <wl@gnu.org> [base] Fix invalid mac font recursion.

(gray_convert_glyph): Remove impossible condition and clean up. 2016-09-29 Werner Lemberg <wl@gnu.org> [pcf] Enrich family name with foundry name and glyph width info. This is a very old patch from openSuSE (from 2006, submitted to FreeType in 2011) that I forgot to apply. https://build.opensuse.org/package/view_file/openSUSE:Factory/freetype2/freetype2-bitmap-foundry.patch Prepend the foundry name plus a space to the family name. There are many fonts just called `Fixed' which look completely different, and which have nothing to do with each other. When selecting `Fixed' in KDE or Gnome one gets results that appear rather random, the style changes often if one changes the size and one cannot select some fonts at all. We also check whether we have `wide' characters; all put together, we get family names like `Sony Fixed' or `Misc Fixed Wide'. * src/pcf/pcfread.c (pcf_load_font): Implement it. * docs/CHANGES: Document it. 2016-09-29 Werner Lemberg <wl@gnu.org> [ftfuzzer] Speed up. * src/tools/ftfuzzer/ftfuzzer.cc (LLVMFuzzerTestOneInput): Don't check for embedded bitmaps if we have a non-default instance. 2016-09-29 Werner Lemberg <wl@gnu.org> [truetype] Disallow bitmap strikes for non-default instances. Also speed up access of default instances if GX variations are active. * include/freetype/internal/tttypes.h (TT_FaceRec): Add `is_default_instance' member. * src/sfnt/sfobjs.c (sfnt_init_face): Initialize `is_default_instance'. * src/truetype/ttgload.c (TT_Process_Simple_Glyph, load_truetype_glyph): Add test for default instance.

This avoids additional calls to `tt_face_lookup_table' for the `glyf' table, which can be expensive. * include/freetype/internal/tttypes.h (TT_LoaderRec): Move `glyf_offset' field to ...

This speeds up FreeType's handling of malformed fonts. * src/truetype/ttinterp.c (TT_RunIns): Set up limits for the number of twilight points, the total number of negative jumps, and the total number of loops in LOOPCALL opcodes. The values are based on the number of points and entries in the CVT table. (Ins_JMPR): Test negative jump counter. (Ins_LOOPCALL): Test loopcall counter. * src/truetype/ttinterp.h (TT_ExecContext): Updated. * docs/CHANGES: Updated. 2016-09-25 Werner Lemberg <wl@gnu.org> [truetype] Sanitize only last entry of `loca' table. Without this patch, a loca sequence like `0 100000 0 100000 ...', where value 100000 is larger than the `glyf' table size, makes FreeType handle the whole `glyf' table as a single glyph again and again, which is certainly invalid (and can be very slow, too). * src/truetype/ttpload.c (tt_face_get_location): Implement.

The algorithm calls `gray_set_cell' at the start of each new contour or when the contours cross the cell boundaries. Double-checking for that is wasteful. * src/smooth/ftgrays.c (gray_set_cell): Remove check for a new cell. (gray_convert_glyph): Remove initialization introduced by 44b172e88. 2016-09-10 Werner Lemberg <wl@gnu.org> [sfnt] Fix previous commit. Problems reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=40 We now map the strike index right before accessing the physical data, not earlier. * src/sfnt/sfobjs.c (sfnt_load_face): Set `face->sbit_strike_map' after creating the map so that... * src/sfnt/ttsbit.c (tt_face_load_strike_metrics): ... this function can be used before and after setting up `sbit_strike_map'.

Use better values for call to `FT_Set_Char_Size'. 2016-09-09 Werner Lemberg <wl@gnu.org> [sfnt] Don't provide (completely) broken strike data. FreeType tries to sanitize strike header data; we now reject completely broken ones. * include/freetype/internal/tttypes.h (TT_FaceRec): New `sbit_strike_map' array pointer. * src/base/ftobjs.c (FT_Match_Size): Reject matches where either width or height would be zero. Add tracing message in case of error. * src/sfnt/sfobjs.c (sfnt_load_face): Populate `sbit_strike_map', only using (more or less) valid strike header data for FT_Face's `available_sizes' array.

It turns out that there is significant cost associated with `FT_Span' creation and calls to `gray_render_span' because it happens so frequently. This removes these steps from our internal use but leaves it alone for `FT_RASTER_FLAG_DIRECT" to preserve API. The speed gain is about 5%. * src/smooth/ftgrays.c (gray_render_span): Removed. The code is migrated to... (gray_hline): ... here. 2016-08-30 Alexei Podtelezhnikov <apodtele@gmail.com> [smooth] Streamline pixmap drawing a bit more.

This removes unnecessary complexity of span merging and buffering. Instead, the spans are rendered as they come, speeding up the rendering by about 5% as a result. * src/smooth/ftgrays.c [FT_MAX_GRAY_SPANS]: Macro removed. (gray_TWorker): Remove span buffer and related fields. (gray_sweep, gray_hline): Updated. * include/freetype/ftimage.h: Remove documentation note about `FT_MAX_GRAY_SPANS', which was never in `ftoption.h' and is now gone. 2016-08-16 Werner Lemberg <wl@gnu.org> [truetype] Fix `MPS' instruction.

It first gets the advance value from the font table and then scales it by the `font->size->metrics->x_scale' field. But `FT_Select_Size' doesn't set that value for bitmap fonts and the advance gets scaled to zero. Taken from https://github.com/behdad/harfbuzz/issues/252 * src/sfnt/ttsbit.c (tt_face_load_strike_metrics) <TT_SBIT_TABLE_TYPE_EBLC>: Set scale values. 2016-08-06 Behdad Esfahbod <behdad@behdad.org> [truetype] Fix GX variation handling of composites. * src/truetype/ttgload.c (load_truetype_glyph) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: Check `ARGS_ARE_XY_VALUES' flag. 2016-08-05 Alexei Podtelezhnikov <apodtele@gmail.com> [smooth] Minor refactoring. * src/smooth/ftgrays.c (gray_render_scanline, gray_render_line): Updated. 2016-07-29 Werner Lemberg <wl@gnu.org> [sfnt, truetype] Don't abort on invalid `maxComponentDepth'.

Instead, simply adjust its value and emit a tracing message. 2016-07-26 Werner Lemberg <wl@gnu.org> * src/autofit/aflatin.c (af_latin_metrics_scale_dim): Minor. No functional change. 2016-07-22 Hin-Tak Leung <htl10@users.sourceforge.net> [truetype] Record the end of IDEFs. To match the logic in FDEF. The value of the end is only used for bound-checking in `Ins_JMPR', so it may not have been obvious that it was not recorded. Tested (as part of Font Validator 2.0) all the fonts on Fedora and did not see any change. * src/truetype/ttinterp.c (Ins_IDEF): Updated. 2016-07-19 Werner Lemberg <wl@gnu.org> [truetype] Sanitizer fix, second try. * src/truetype/ttgxvar.c (ft_var_readpackedpoints): Fix boundary tests and use only one slot more. 2016-07-19 Werner Lemberg <wl@gnu.org> [truetype] Sanitizer fix. * src/truetype/ttgxvar.c (ft_var_readpackedpoints): Increase array to fix nested loops. 2016-07-18 Werner Lemberg <wl@gnu.org> [truetype] Make GETDATA work only for GX fonts. * src/truetype/ttinterp.c (opcode_name): Updated. (Ins_GETDATA): Only define for `TT_CONFIG_OPTION_GX_VAR_SUPPORT'. (TT_RunIns): Updated. 2016-07-17 Werner Lemberg <wl@gnu.org> [truetype] Add support for Apple's GETDATA[], opcode 0x92 bytecode instruction. It always returns 17, and we have absolutely no idea what it is good for... * src/truetype/ttinterp.c (Pop_Push_Count, opcode_name): Updated. (Ins_GETDATA): New function. (TT_RunIns): Add it. 2016-07-16 Werner Lemberg <wl@gnu.org> [truetype] Add bytecode support for GX variation fonts. This commit implements undocumented (but confirmed) stuff from Apple's old bytecode engine. GETVARIATION[], opcode 0x91 This opcode pushes normalized variation coordinates for all axes onto the stack (in 2.14 format). Coordinate of first axis gets pushed first. GETINFO[], selector bit 3 If GX variation support is enabled, bit 10 of the result is set to 1. * src/truetype/ttinterp.c: Include FT_MULTIPLE_MASTERS_H. (opcode_name) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: Updated. (Ins_GETINFO) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: Handle selector bit 3, checking support for variation glyph hinting. (Ins_GETVARIATION) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: New function to implement opcode 0x91. (TT_RunIns) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: Handle opcode 0x91. 2016-07-16 Werner Lemberg <wl@gnu.org> [truetype] Fix GETINFO bytecode instruction. * src/truetype/ttinterp.c (Ins_GETINFO): Fix return value for stretching information. 2016-07-16 Behdad Esfahbod <behdad@behdad.org> [truetype] Make all glyphs in `Zycon' GX font work. * src/truetype/ttgxvar.c (ft_var_readpackedpoints): Fix boundary tests. 2016-07-16 Werner Lemberg <wl@gnu.org> [truetype] Fix GX delta tracing. * src/truetype/ttgxvar.c (TT_Vary_Apply_Glyph_Deltas): Trace relative point movements. 2016-07-16 Behdad Esfahbod <behdad@behdad.org> [truetype] More fixes for GX. This finally fixes the rendering of the cyclist and the lizard in the `Zycon' font. * src/truetype/ttgxvar.c (ft_var_readpackedpoints): `first' point index is always cumulative. (tt_handle_deltas): Rename to... (tt_interpolate_deltas): ... This. Add new parameter for output point array. Update caller. (TT_Vary_Apply_Glyph_Deltas): Add `points_out' array; it now holds the intermediate results of `tt_interpolate_deltas' that are to be added to `outline->points'. 2016-07-15 Werner Lemberg <wl@gnu.org> * src/autofit/aflatin.c (af_latin_hints_compute_segments): Thinko. `max_pos' is always larger than `min_pos' so `FT_ABS' is not needed. Reported by Alexei. 2016-07-16 Nikolaus Waxweiler <madigens@gmail.com> * src/truetype/ttinterp.c (Ins_MIRP): Fix copy-and-paste error. Problem reported by Hin-Tak Leung. 2016-07-15 Werner Lemberg <wl@gnu.org> [autofit] Update and improve segment and edge tracing. * src/autofit/afhints.c (af_glyph_hints_dump_segments): Trace `delta' also. Don't show first point of segment as a replacement for `pos'; this is (a) misleading, since the difference to `pos' can be almost arbitrarily large in corner cases, and (b) it is better to have all segment data in font units instead of a single value given in output space coordinates. Improve layout. (af_glyph_hints_dump_edges): Show px->units and units->px conversion values for convenience. Improve layout. 2016-07-15 Werner Lemberg <wl@gnu.org> [autofit] For edges, reject segments wider than 1px (#41334). * src/autofit/afhints.h (AF_SegmentRec): New member `delta'. * src/autofit/aflatin.c (af_latin_hints_compute_segments): Compute `delta'. (af_latin_hints_compute_edges): Reject segments with a delta larger than 0.5px. 2016-07-14 Werner Lemberg <wl@gnu.org> * include/freetype/freetype.h (FT_IS_NAMED_INSTANCE): New macro. 2016-07-14 Werner Lemberg <wl@gnu.org> [sfnt] Fix `face_index' value in `FT_Face' for named instances. * src/sfnt/sfobjs.c (sfnt_init_face): Don't strip off higher 16bits. 2016-07-14 Werner Lemberg <wl@gnu.org> * src/truetype/ttgxvar.c (TT_Vary_Apply_Glyph_Deltas): Fix tracing. 2016-07-14 Behdad Esfahbod <behdad@behdad.org> [truetype] Fix gxvar delta interpolation. The coordinates of the base font should be used for interpolation purposes, NOT the current points (i.e., the result of accumulation of previous deltas). * src/truetype/ttgxvar.c (TT_Vary_Apply_Glyph_Deltas): Initialize `points_org' before looping over all tuples. ---------------------------------------------------------------------------- Copyright (C) 2016-2022 by David Turner, Robert Wilhelm, and Werner Lemberg.

Add better documentation to the comment. (FTC_ImageCache_LookupScaler): Ditto. (FTC_SBitCache_Lookup): Ditto. (FTC_SBitCache_LookupScaler): Ditto. 2017-09-13 Werner Lemberg <wl@gnu.org> [autofit] Really fix #41334 (#52000). * src/autofit/aflatin.c (af_latin_hints_compute_segments): Set `segment->delta' everywhere. 2017-09-12 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> [autofit, sfnt] Fix for `make multi'. * src/autofit/afshaper.c: Include FT_ADVANCE_H, to use FT_Get_Advance() in it. * src/sfnt/ttcmap.c: Include FT_SERVICE_POSTSCRIPT_CMAPS_H to use PS_Unicodes in it, also include `ttpost.h' to use tt_face_get_ps_name() in it. 2017-09-11 Azzuro <azzuro@team-mediaportal.com> [build] Improve builds with different MS Visual Studio versions. * builds/windows/vc2010/freetype.vcxproj: Switch platform toolset according to the Visual Studio version. 2017-09-11 Werner Lemberg <wl@gnu.org> * src/sfnt/ttkern.c (tt_face_load_kern): Reject format 2 tables. Reported by Behdad. 2017-09-09 Werner Lemberg <wl@gnu.org> [autofit] Improve communication with ftgrid. * src/autofit/afhints.c (af_glyph_hints_get_segment_offset): Provide values in font units. 2017-09-08 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> [base] Remove a check for resource ID in the resource fork driver. LastResort.dfont has a marginal resource ID 0xFFFF for sfnt resource. Inside Macintosh: More Macintosh Toolbox, `Resource IDs' (1-46), tells that some IDs are reserved and should not be used. FreeType2 just uses resource ID to sort the fragmented resource. To accept the marginal fonts, the checking is removed. * src/base/ftrfork.c (FT_Raccess_Get_DataOffsets): Remove res_id validity check, fix a trace message format. 2017-09-08 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> [sfnt, truetype] Register the tags for marginal fonts. The first 32bit of standard TrueType variants is 0x00010000, `OTTO', `ttcf', `true' or `typ1'. 2 marginal dfonts on legacy Mac OS X, Keyboard.dfont and LastResort.dfont, have the sfnt resources starting 0xA5 followed by `kbd' or `lst'. Considering the following data could be parsed as conventional TrueType fonts, the header checking is updated to allow these tags. It seems that recent Mac OS X has already switched to normal TTF for these fonts. See the discussion at http://u88.n24.queensu.ca/exiftool/forum/index.php?topic=3931.0 * include/freetype/tttags.h (TTAG_0xA5kbd, TTAG_0xA5lst): New header tags for Keyboard.dfont and LastResort.dfont. * src/sfnt/sfobjs.c (sfnt_open_font): Accept the sfnt resource starts with TTAG_0xA5kbd or TTAG_0xA5lst. * src/truetype/ttobjs.c (tt_face_init): Accept the face with the format tag is TTAG_0xA5kbd or TTAG_0xA5lst. 2017-09-05 Werner Lemberg <wl@gnu.org> Fix multiple calls of `FT_Bitmap_Convert'. The documentation of `FT_Bitmap_Convert' says that multiple calls do proper reallocation of the target FT_Bitmap object. However, this failed for the sequence non-empty bitmap empty bitmap non-empty bitmap Reason was that `FT_Bitmap_Convert' only reallocated the bitmap buffer if it became too small; it didn't make the buffer smaller. For an empty bitmap following a non-empty one, only the buffer dimension got set to zero, without deallocation. If the next call was a non-empty buffer again, an assertion in `ft_mem_qrealloc' was triggered. * src/base/ftbitmap.c (FT_Bitmap_Convert): Always reallocate target buffer to the correct size. * docs/CHANGES: Document it. 2017-09-05 Werner Lemberg <wl@gnu.org> [bdf] Fix size and resolution handling. * src/bdf/bdfdrivr.c (BDF_Face_Init): Use `SIZE' values if `POINT_SIZE', `RESOLUTION_X', or `RESOLUTION_Y' properties are missing. * docs/CHANGES: Document it. 2017-08-25 Alexei Podtelezhnikov <apodtele@gmail.com> Swap `ALLOC_MULT' arguments (#51833). * src/base/ftbitmap.c (ft_bitmap_assure_buffer): Updated. * src/winfonts/winfnt.c (FNT_Load_Glyph): Updated. * src/raster/ftrend1.c (ft_raster1_render): Updated. 2017-08-23 Werner Lemberg <wl@gnu.org> [sfnt] Fix clang compilation (#51788). * src/sfnt/pngshim.c (premultiply_data): Use vectors instead of scalars. (vector_shuffle): New macro to take care of a different built-in function name on clang. 2017-08-22 Werner Lemberg <wl@gnu.org> [base] Don't zero out allocated memory twice (#51816). Patch applied from bug report. * src/base/ftutil.c (ft_mem_qrealloc): Use low-level allocation to avoid unnecessary overhead. 2017-08-22 Werner Lemberg <wl@gnu.org> [truetype] Integer overflow. Changes triggered by https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=3107 * src/truetype/ttinterp.c (Ins_MDRP, Ins_MIRP, Ins_ALIGNPTS): Use NEG_LONG. 2017-08-17 Alexei Podtelezhnikov <apodtele@gmail.com> [sfnt] Avoid synthetic unicode for symbol fonts with PUA. Reported as https://bugs.chromium.org/p/chromium/issues/detail?id=754574 * src/sfnt/sfobjs.c (sfnt_load_face): Check for FT_ENCODING_MS_SYMBOL. 2017-08-16 Werner Lemberg <wl@gnu.org> * src/sfnt/pngshim.c (premultiply_data): Fix compiler warnings. 2017-08-15 Behdad Esfahbod <behdad@behdad.org> [sfnt] Speed up PNG image loading. This reduces the overhead of `premultiply_data' by 60%. * src/sfnt/pngshim.c (premultiply_data): Provide code which uses gcc's (and clang's) `vector_byte' attribute to process 4 pixels at a time. 2017-08-11 Werner Lemberg <wl@gnu.org> [sfnt, truetype] Improve handling of missing sbits. Requested by Behdad. Modern bitmap-only SFNTs like `NotoColorEmoji.ttf' don't contain entries in the bitmap strike(s) for empty glyphs. Instead, they rely that a space glyph gets created from the font's metrics data. This commit makes FreeType behave accordingly. * include/freetype/fterrdef.h (FT_Err_Missing_Bitmap): New error code. * src/sfnt/ttsbit.c (tt_sbit_decoder_load_image): Change error codes to make a distinction between a missing bitmap in a composite and a simple missing bitmap. * src/truetype/ttgload.c (TT_Load_Glyph): For a missing bitmap (in a bitmap-only font), synthesize an empty bitmap glyph if metrics are available. 2017-08-10 Werner Lemberg <wl@gnu.org> [base] Minor API improvement for default variation axis setting. * src/base/ftmm.c (FT_Set_MM_Design_Coordinates, FT_Set_Var_Design_Coordinates, FT_Set_MM_Blend_Coordinates, FT_Set_Var_Blend_Coordinates): Allow coords==NULL if num_coords==0. * docs/CHANGES: Updated. 2017-08-08 Werner Lemberg <wl@gnu.org> [psnames] Really fix issue #49949. We now use a separate preprocessor macro to handle both definition and declaration of the glyph name arrays. * src/psnames/psmodule.c (DEFINE_PS_TABLE_DATA): New macro. * src/tools/glnames.py (StringTable::dump, StringTable::dump_sublist): Use `DEFINE_PS_TABLE_DATA'. (dump_encoding): Ditto. (main): Use `wb' mode for writing the output file, which works on Windows also. * src/psnames/pstables.h: Regenerated. 2017-08-08 Alexei Podtelezhnikov <apodtele@gmail.com> [smooth] Harmony LCD rendering. This is a new technology for LCD-optimized rendering. It capitalizes on the fact that each color channel grid is shifted by a third of a pixel. Therefore it is logical to render 3 separate monochrome bitmaps shifting the outline by 1/3 pixel, and then combine them. Importantly, the resulting output does not require additional LCD filtering. * src/smooth/ftsmooth.c (ft_smooth_render_generic) [!FT_CONFIG_OPTION_SUBPIXEL_RENDERING]: Implement new LCD-optimized rendering. * include/freetype/ftlcdfil.h, include/freetype/freetype.h, include/freetype/config/ftoption.h, devel/ftoption.h: Updated documentation. 2017-08-08 Alexei Podtelezhnikov <apodtele@gmail.com> * src/smooth/ftsmooth.c (ft_smooth_render_generic): Clean up. 2017-08-08 Alexei Podtelezhnikov <apodtele@gmail.com> * src/sfnt/ttpost.c (format): Use otspec-compliant versions. 2017-08-05 Werner Lemberg <wl@gnu.org> [truetype] Integer overflow. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=2868 * src/truetype/ttinterp.c (Ins_ALIGNRP): Use NEG_LONG. 2017-08-05 Werner Lemberg <wl@gnu.org> [base, truetype] New function `FT_Get_Var_Axis_Flags'. The reserved `flags' field got a value in OpenType version 1.8.2; unfortunately, the public `FT_Var_Axis' structure misses the corresponding element. Since we can't add a new field, we add an access function. * src/base/ftmm.c (FT_Get_Var_Axis_Flags): New function. * include/freetype/ftmm.h (FT_VAR_AXIS_FLAG_HIDDEN): New macro. Updated. * src/truetype/ttgxvar.c (TT_Get_MM_Var): Increase allocated memory of `mmvar' to hold axis flags. Fill the axis flags array. * docs/CHANGES: Updated. 2017-08-03 Nikolaus Waxweiler <madigens@gmail.com> [truetype] Fix metrics of B/W hinting in v40 mode. Phantom points are now saved outside v40 backwards compatibility mode. This fixes the jumping glyphs when switching between v35 and v40 monochrome mode. * src/truetype/ttgload.c (TT_Hint_Glyph): Fix inversed bool logic. 2017-08-03 Nikolaus Waxweiler <madigens@gmail.com> [truetype] Do not set any ClearType flags in v40 monochrome mode. This fixes weird behavior of instructions that resulted in rendering differences between v35 and v40 in monochrome mode, e.g., in `timesbi.ttf'. * src/truetype/ttinterp.c (Ins_GETINFO) [TT_SUPPORT_SUBPIXEL_HINTING_MINIMAL]: Check `subpixel_hinting_lean'. 2017-08-01 Werner Lemberg <wl@gnu.org> * src/truetype/ttgxvar.c (TT_Get_MM_Var): Fix thinko. 2017-08-01 Behdad Esfahbod <behdad@behdad.org> [truetype] Fix loading of named instances. * src/truetype/ttgxvar.c (TT_Get_MM_Var): Preserve file position while loading the `avar' table. 2017-08-01 Werner Lemberg <wl@gnu.org> [sfnt, truetype] Minor adjustments for OpenType 1.8.2. * src/sfnt/sfobjs.c (sfnt_load_face): The units per EM value has now (tighter) limits. * src/truetype/ttgload.c (load_truetype_glyph): The new OpenType version explicitly allows all negative values for the number of contours if we have a composite glyph (this is for better backwards compatibility I guess), but it still recommends value -1. 2017-07-26 Werner Lemberg <wl@gnu.org> [cff] Integer overflow. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=2738 * src/cff/cf2hints.c (cf2_glyphpath_computeOffset, cf2_glyphpath_curveTo): Use ADD_INT32. 2017-07-13 Werner Lemberg <wl@gnu.org> [base] Fix memory leak.

This commit (mainly for 32bit CPUs) is the first of a series of similar commits to handle known integer overflows. Basically, all of them are harmless, since they affect rendering of glyphs only, not posing security threats. It is expected that fuzzying will show up more overflows, to be fixed in due course. The idea is to mark places where overflows can occur, using macros that simply cast to unsigned integers, because overflow arithmetic is well defined in this case. Doing so suppresses run-time errors of sanitizers without adding computational overhead. * include/freetype/internal/ftcalc.h (OVERFLOW_ADD_INT, OVERFLOW_SUB_INT, OVERFLOW_MUL_INT, OVERFLOW_ADD_LONG, OVERFLOW_SUB_LONG, OVERFLOW_MUL_LONG): New macros. * src/base/ftcalc.c (FT_RoundFix, FT_CeilFix, FT_Matrix_Multiply, FT_Matrix_Multiply_Scaled, FT_Vector_Transform_Scaled, ft_corner_orientation): Use new macros. * src/base/ftoutln.c (FT_Outline_Get_Orientation): Use new macros. 2017-05-28 Werner Lemberg <wl@gnu.org> * include/freetype/internal/ftcalc.h (FLOAT_TO_FIXED): Remove.

The new name better describes what the macro actually does; additionally, we don't need a trailing `f' for literals (there was only a single such instance in the code, but this caused a clang warning because the macro itself uses `double' literals). * src/cff/cf2blues.c, src/cff/cf2blues.h, src/cff/cf2fixed.h, src/cff/cf2font.c, src/cff/cf2hints.c: Updated. 2017-05-28 Werner Lemberg <wl@gnu.org> Fix negation of INT_MIN and LONG_MIN (#46149). * src/base/ftcalc.c (FT_MOVE_SIGN): Add argument to pass unsigned value, to be used as the result.

Extra bitmap padding for LCD filtering depends on the filter. The default 5-tap filter needs 2 extra subpixels. The light 3-tap filter needs only 1 extra subpixel. This space could be already available due to rounding. In order to optimize the padding, we now expand CBox for the given filter weights before rounding.

This mode uses fractional advance widths and doesn't scale glyphs horizontally, only applying vertical scaling and hinting. At the same time, the behaviour of the `light' auto-hinter gets restored for backward compatibility: Both vertical and horizontal scaling is again based on rounded metrics values (this was changed in a commit from 2017-03-30 as a side effect). To be more precise, the behaviour is restored for TrueType fonts only; for other font formats like Type 1, this is a new feature of the `light' hinting mode. * include/freetype/freetype.h (FT_LOAD_TARGET_SLIGHT): New macro.

Problem reported as https://github.com/google/fonts/issues/632 The font in question (Nunito) has values 705 and 713 for the reference and overshoot values, respectively, of the first blue zone. Blue zone 2, however, has value 710 for both the reference and overshoot. At 12ppem, reference and overshoot of blue zone 0 becomes 8px, while blue zone 2 becomes 9px. A peculiarity of this font is that the tops of isolated vertical stems like `N' have a slight overshoot also. The auto-hinter tries to find the nearest blue zone using the original coordinates. For vertical stems, this is value 713. For normal horizontal tops like in character `E', this is value 710. Since value 713 is mapped to 8px but value 710 to 9px, `N' and similar characters are one pixel higher than `E', which looks very bad. This commit sanitizes blue zones to avoid such a behaviour. * src/autofit/aflatin.c (af_latin_sort_blue): New function. (af_latin_metrics_init_blues): Sort blue values and remove overlaps. 2017-02-12 Alexei Podtelezhnikov <apodtele@gmail.com> * src/smooth/ftgrays.c (gray_sweep): Improve code. 2017-02-06 Werner Lemberg <wl@gnu.org> [truetype] Implement `VVAR' table support. * src/truetype/ttgxvar.h (GX_HVarTable): Renamed to...

The number of lowercase characters for computing the top flat blue zone value was too small (in most cases only `x' and `z'). If one of the two characters has a large serif, say, it can happen that FreeType must select between two different values, having a 50% chance to use the wrong one. As a result, rendering at larger PPEM values could yield uneven lowercase glyph heights. Problem reported by Christoph Koeberlin <christoph@koe.berlin>. * src/autofit/afblue.dat (AF_BLUE_STRING_LATIN_SMALL): Replaced with...

This brings up the minimum required CMake version to 2.8.12. The installation paths follow the GNU defaults now, e.g. installing on a 64 bit host will place binaries into the lib64/ folder on e.g. Fedora. Symbols are hidden by default (e.g. `-fvisibility=hidden' on GCC). CMake will no longer look for a C++ compiler. Library and .so version now match the Autotools build. Comments in the build file and informational messages now use platform agnostic example commands. ftoption.h and ftconfig.h are written directly without a redundant `-new' copy. External dependencies are expressed as option()s and will turn up as such in cmake-gui. Internal: Properties such as dependencies and include directories are now privately set on the freetype library instead of globally. The CPack definitions have been cleaned up, the `make dist' has been removed. Source packages generated with CPack don't contain Autotools files and aren't used by the maintainers anyway. On Windows, src/base/ftver.rc is compiled to decorate the library with version and copyright information. A pkg-config file is now generated and installed. 2018-04-09 Werner Lemberg <wl@gnu.org> [truetype] Integer overflow issues.

Do not limit DLL builds to MinGW, since we already have `__declspec(dllexport)' directives in `ftconfig.h'. Also suppress more warnings for POSIX functions. 2018-03-08 Hugh McMaster <hugh.mcmaster@outlook.com> Make installation of `freetype-config' optional (#53093). * builds/unix/configure.raw: Add option `--enable-freetype-config' and set `INSTALL_FT2_CONFIG'. * builds/unix/unix-def.in (INSTALL_FT2_CONFIG): Define. * builds/unix/install.mk (install): Handle it. 2018-03-05 Werner Lemberg <wl@gnu.org> Make `ftlcdfil.c' part of the `base' module. `ftobjs.c' needs `ft_lcd_padding'.

The subsetted demo font of the report that exhibits the bug has a very unusual type 2 cmap for Unicode(!): It contains only two sub-headers, one for one-byte characters (covering the range 0x20 to 0xFA), and a second one for higher byte 0x01 (just for character code U+0131).

In version 2.6.1, this has been disallowed to better reject malformed fonts; however, this restriction was too strong. This time, we only take the first 256 elements into account, since encoding arrays are always accessed with a 8bit integer, according to the PostScript Language Reference. * src/type1/t1load.c (parse_encoding): Implement it. 2017-11-27 Jan Alexander Steffens (heftig) <jan.steffens@gmail.com> Fix last commit (#52522). * builds/freetype.mk: Set `FT_OPTION_H' and `FTOPTION_FLAG' properly if we have `ftoption.h' in `BUILD_DIR'. 2017-11-24 Werner Lemberg <wl@gnu.org> [unix] Install a massaged `ftoption.h' file (#51780). * builds/unix/configure.raw (ftoption_set, ftoption_unset): New auxiliary functions to construct... (FTOPTION_H_SED): ... this new variable. Apply it as a sed argument while copying `ftoption.h' to the `builds/unix' directory (using `AC_CONFIG_FILES'). Simplify code of test that checks cpp's computation of bit length (the test previously created an empty `ftoption.h' file and deleted it immediately afterwards); without this change, it can happen on my GNU/Linux box that `configure's execution of `config.status' doesn't create `ftoption.h' (no idea why this happens). * builds/unix/install.mk (install): Install `builds/unix/ftoption.h'. * builds/unix/unix-def.in (DISTCLEAN): Updated. * builds/unix/.gitignore: Updated. 2017-11-23 Tor Andersson <tor.andersson@artifex.com> Silence unused function warnings (#52465).

(#52466) Glyph advance widths were being written to the new `PS_Decoder' but not saved to the underlying format specific decoder. This caused pure CFF fonts to have bad advance width. * include/freetype/internal/psaux.h (PS_Decoder): Change `glyph_width' field to pointer.

Since Ewald Hew factored the Adobe hinting engine out of the CFF driver code, we can now use it on Type 1 (and CID) font formats, as both have the same hinting philosophy. This change activates the Adobe hinter when in LIGHT mode, and therefore always unless explicitly asking for the auto-hinter. This makes LIGHT behavior consistent with CFF fonts. As of this commit, the hinting engine table looks as follows.

(#52251) The interpreter in Type 1 mode rewinds the charstring after collecting all hints for building the initial hintmap (commit d52dd7f). However, some charstrings use `endchar' in a final subroutine call, rewinding to the start of that subroutine, and only a small section of the actual glyph is drawn. * src/psaux/psintrp.c (cf2_interpT2CharString) <cf2_cmdENDCHAR>: Ensure we are on the top level charstring before rewinding. 2017-11-03 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> [truetype] Add more tricky fonts. See the report by Yang Yinsen. https://lists.gnu.org/archive/html/freetype-devel/2017-11/msg00000.html * src/truetype/ttobjs.c (trick_names): Add `DFGothic-EB', `DFGyoSho-Lt', `DFHSGothic-W5', `DFHSMincho-W3' and `DFHSMincho-W7'.

Also add checksums for DLCLiShu and DLCHayBold which their family names were already listed but their checksums were previously unknown. 2017-11-01 Alexei Podtelezhnikov <apodtele@gmail.com> [smooth] Fix complex rendering at high ppem. We used to split large glyphs into horizontal bands and continue bisecting them still horizontally if that was not enough. This is guaranteed to fail when a single scanline cannot fit into the rendering memory pool. Now we bisect the bands vertically so that the smallest unit is a column of the band height, which is guranteed to fit into memory. * src/smooth/ftgrays.c (gray_convert_glyph): Implement it. 2017-10-20 Alexei Podtelezhnikov <apodtele@gmail.com> [smooth] Improve complex rendering at high ppem. At large sizes almost but not exactly horizontal segments can quickly drain the rendering pool. This patch at least avoids filling the pool with trivial cells. Beyond this, we can only increase the pool size.

Synthesize a `SubFont' object for Type 1 fonts. This is used in the interpreter to access Private dict data, which are stored in different places for Type 1 and CFF. This allows the same data to be used in either mode. * src/psaux/psobjs.c (t1_make_subfont): New procedure to copy required values to a dummy `CFF_SubFont' object. This is similar to `cff_make_private_dict'. * src/psaux/psobjs.h: Add the new declaration. * include/freetype/internal/psaux.h, src/psaux/psauxmod.c: Ditto. Add this to the PSAux Service for future use with CID fonts. * src/type1/t1gload.c: Include FT_INTERNAL_CFF_TYPES_H.

How FreeType's rasterizer work by David Turner Revised 2007-Feb-01 This file is an attempt to explain the internals of the FreeType rasterizer. The rasterizer is of quite general purpose and could easily be integrated into other programs. I. Introduction II. Rendering Technology 1. Requirements 2. Profiles and Spans a. Sweeping the Shape b. Decomposing Outlines into Profiles c. The Render Pool d. Computing Profiles Extents e. Computing Profiles Coordinates f. Sweeping and Sorting the Spans I. Introduction =============== A rasterizer is a library in charge of converting a vectorial representation of a shape into a bitmap. The FreeType rasterizer has been originally developed to render the glyphs found in TrueType files, made up of segments and second-order Béziers. Meanwhile it has been extended to render third-order Bézier curves also. This document is an explanation of its design and implementation. While these explanations start from the basics, a knowledge of common rasterization techniques is assumed. II. Rendering Technology ======================== 1. Requirements --------------- We assume that all scaling, rotating, hinting, etc., has been already done. The glyph is thus described by a list of points in the device space. - All point coordinates are in the 26.6 fixed float format. The used orientation is: ^ y \| reference orientation \| ----> x 0 `26.6' means that 26 bits are used for the integer part of a value and 6 bits are used for the fractional part. Consequently, the `distance' between two neighbouring pixels is 64 `units' (1 unit = 1/64th of a pixel). Note that, for the rasterizer, pixel centers are located at integer coordinates. The TrueType bytecode interpreter, however, assumes that the lower left edge of a pixel (which is taken to be a square with a length of 1 unit) has integer coordinates. ^ y ^ y \| \| \| (1,1) \| (0.5,0.5) +-----------+ +-----+-----+ \| \| \| \| \| \| \| \| \| \| \| \| \| o-----+-----> x \| \| \| (0,0) \| \| \| \| \| o-----------+-----> x +-----------+ (0,0) (-0.5,-0.5) TrueType bytecode interpreter FreeType rasterizer A pixel line in the target bitmap is called a `scanline'. - A glyph is usually made of several contours, also called `outlines'. A contour is simply a closed curve that delimits an outer or inner region of the glyph. It is described by a series of successive points of the points table. Each point of the glyph has an associated flag that indicates whether it is `on' or `off' the curve. Two successive `on' points indicate a line segment joining the two points. One `off' point amidst two `on' points indicates a second-degree (conic) Bézier parametric arc, defined by these three points (the `off' point being the control point, and the `on' ones the start and end points). Similarly, a third-degree (cubic) Bézier curve is described by four points (two `off' control points between two `on' points). Finally, for second-order curves only, two successive `off' points forces the rasterizer to create, during rendering, an `on' point amidst them, at their exact middle. This greatly facilitates the definition of successive Bézier arcs. The parametric form of a second-order Bézier curve is: P(t) = (1-t)^2P1 + 2t(1-t)P2 + t^2P3 (P1 and P3 are the end points, P2 the control point.) The parametric form of a third-order Bézier curve is: P(t) = (1-t)^3P1 + 3t(1-t)^2P2 + 3t^2(1-t)P3 + t^3P4 (P1 and P4 are the end points, P2 and P3 the control points.) For both formulae, t is a real number in the range [0..1]. Note that the rasterizer does not use these formulae directly. They exhibit, however, one very useful property of Bézier arcs: Each point of the curve is a weighted average of the control points. As all weights are positive and always sum up to 1, whatever the value of t, each arc point lies within the triangle (polygon) defined by the arc's three (four) control points. In the following, only second-order curves are discussed since rasterization of third-order curves is completely identical. Here some samples for second-order curves. * # on curve * off curve __---__ #-__ _-- -_ --__ _- - --__ # \ --__ # -# Two `on' points Two `on' points and one `off' point between them * # __ Two `on' points with two `off' \ - - points between them. The point \ / \ marked `0' is the middle of the - 0 \ `off' points, and is a `virtual -_ _- # on' point where the curve passes. -- It does not appear in the point * list. 2. Profiles and Spans --------------------- The following is a basic explanation of the _kind_ of computations made by the rasterizer to build a bitmap from a vector representation. Note that the actual implementation is slightly different, due to performance tuning and other factors. However, the following ideas remain in the same category, and are more convenient to understand. a. Sweeping the Shape The best way to fill a shape is to decompose it into a number of simple horizontal segments, then turn them on in the target bitmap. These segments are called `spans'. __---__ _-- -_ _- - - \ / \ / \ \| \ __---__ Example: filling a shape _----------_ with spans. _-------------- ----------------\ /-----------------\ This is typically done from the top / \ to the bottom of the shape, in a \| \| \ movement called a `sweep'. V __---__ _----------_ _-------------- ----------------\ /-----------------\ /-------------------\ \|---------------------\ In order to draw a span, the rasterizer must compute its coordinates, which are simply the x coordinates of the shape's contours, taken on the y scanlines. /---/ \|---\| Note that there are usually /---/ \|---\| several spans per scanline. \| /---/ \|---\| \| /---/_______\|---\| When rendering this shape to the V /----------------\| current scanline y, we must /-----------------\| compute the x values of the a /----\| \|---\| points a, b, c, and d. - - - * * - - - - * * - - y - / / b c\| \|d /---/ \|---\| /---/ \|---\| And then turn on the spans a-b /---/ \|---\| and c-d. /---/_______\|---\| /----------------\| /-----------------\| a /----\| \|---\| - - - ####### - - - - ##### - - y - / / b c\| \|d b. Decomposing Outlines into Profiles For each scanline during the sweep, we need the following information: o The number of spans on the current scanline, given by the number of shape points intersecting the scanline (these are the points a, b, c, and d in the above example). o The x coordinates of these points. x coordinates are computed before the sweep, in a phase called `decomposition' which converts the glyph into profiles. Put it simply, a `profile' is a contour's portion that can only be either ascending or descending, i.e., it is monotonic in the vertical direction (we also say y-monotonic). There is no such thing as a horizontal profile, as we shall see. Here are a few examples: this square 1 2 ---->---- is made of two \| \| \| \| \| \| profiles \| \| ^ v ^ + v \| \| \| \| \| \| \| \| ----<---- up down this triangle P2 1 2 \|\ is made of two \| \ ^ \| \ \ \| \ \| \| \ \ profiles \| \ \| \| \| \ v ^ \| \ \| \| \ \| \| + \ v \| \ \| \| \ P1 ---___ \ ---___ \ ---_\ ---_ \ <--__ P3 up down A more general contour can be made of more than two profiles: __ ^ / \| / ___ / \| / \| / \| / \| / \| \| \| / / => \| v / / \| \| \| \| \| \| ^ \| ^ \| \|___\| \| \| ^ + \| + \| + v \| \| \| v \| \| \| \| \| up \| \|___________\| \| down \| <-- up down Successive profiles are always joined by horizontal segments that are not part of the profiles themselves. For the rasterizer, a profile is simply an array that associates one horizontal pixel coordinate to each bitmap scanline crossed by the contour's section containing the profile. Note that profiles are oriented up or down along the glyph's original flow orientation. In other graphics libraries, profiles are also called `edges' or `edgelists'. c. The Render Pool FreeType has been designed to be able to run well on _very_ light systems, including embedded systems with very few memory. A render pool will be allocated once; the rasterizer uses this pool for all its needs by managing this memory directly in it. The algorithms that are used for profile computation make it possible to use the pool as a simple growing heap. This means that this memory management is actually quite easy and faster than any kind of malloc()/free() combination. Moreover, we'll see later that the rasterizer is able, when dealing with profiles too large and numerous to lie all at once in the render pool, to immediately decompose recursively the rendering process into independent sub-tasks, each taking less memory to be performed (see `sub-banding' below). The render pool doesn't need to be large. A 4KByte pool is enough for nearly all renditions, though nearly 100% slower than a more comfortable 16KByte or 32KByte pool (that was tested with complex glyphs at sizes over 500 pixels). d. Computing Profiles Extents Remember that a profile is an array, associating a _scanline_ to the x pixel coordinate of its intersection with a contour. Though it's not exactly how the FreeType rasterizer works, it is convenient to think that we need a profile's height before allocating it in the pool and computing its coordinates. The profile's height is the number of scanlines crossed by the y-monotonic section of a contour. We thus need to compute these sections from the vectorial description. In order to do that, we are obliged to compute all (local and global) y extrema of the glyph (minima and maxima). P2 For instance, this triangle has only two y-extrema, which are simply \|\ \| \ P2.y as a vertical maximum \| \ P3.y as a vertical minimum \| \ \| \ P1.y is not a vertical extremum (though \| \ it is a horizontal minimum, which we P1 ---___ \ don't need). ---_\ P3 Note that the extrema are expressed in pixel units, not in scanlines. The triangle's height is certainly (P3.y-P2.y+1) pixel units, but its profiles' heights are computed in scanlines. The exact conversion is simple: - min scanline = FLOOR ( min y ) - max scanline = CEILING( max y ) A problem arises with Bézier Arcs. While a segment is always necessarily y-monotonic (i.e., flat, ascending, or descending), which makes extrema computations easy, the ascent of an arc can vary between its control points. P2 * # on curve * off curve __-x--_ _-- -_ P1 _- - A non y-monotonic Bézier arc. # \ - The arc goes from P1 to P3. \ \ P3 # We first need to be able to easily detect non-monotonic arcs, according to their control points. I will state here, without proof, that the monotony condition can be expressed as: P1.y <= P2.y <= P3.y for an ever-ascending arc P1.y >= P2.y >= P3.y for an ever-descending arc with the special case of P1.y = P2.y = P3.y where the arc is said to be `flat'. As you can see, these conditions can be very easily tested. They are, however, extremely important, as any arc that does not satisfy them necessarily contains an extremum. Note also that a monotonic arc can contain an extremum too, which is then one of its `on' points: P1 P2 #---__ * P1P2P3 is ever-descending, but P1 -_ is an y-extremum. - ---_ \ -> \ \ P3 # Let's go back to our previous example: P2 * # on curve * off curve __-x--_ _-- -_ P1 _- - A non-y-monotonic Bézier arc. # \ - Here we have \ P2.y >= P1.y && \ P3 P2.y >= P3.y (!) # We need to compute the vertical maximum of this arc to be able to compute a profile's height (the point marked by an `x'). The arc's equation indicates that a direct computation is possible, but we rely on a different technique, which use will become apparent soon. Bézier arcs have the special property of being very easily decomposed into two sub-arcs, which are themselves Bézier arcs. Moreover, it is easy to prove that there is at most one vertical extremum on each Bézier arc (for second-degree curves; similar conditions can be found for third-order arcs). For instance, the following arc P1P2P3 can be decomposed into two sub-arcs Q1Q2Q3 and R1R2R3: P2 * # on curve * off curve original Bézier arc P1P2P3. __---__ _-- --_ _- -_ - - / \ / \ # # P1 P3 P2 * Q3 Decomposed into two subarcs Q2 R2 Q1Q2Q3 and R1R2R3 * __-#-__ * _-- --_ _- R1 -_ Q1 = P1 R3 = P3 - - Q2 = (P1+P2)/2 R2 = (P2+P3)/2 / \ / \ Q3 = R1 = (Q2+R2)/2 # # Q1 R3 Note that Q2, R2, and Q3=R1 are on a single line which is tangent to the curve. We have then decomposed a non-y-monotonic Bézier curve into two smaller sub-arcs. Note that in the above drawing, both sub-arcs are monotonic, and that the extremum is then Q3=R1. However, in a more general case, only one sub-arc is guaranteed to be monotonic. Getting back to our former example: Q2 * __-x--_ R1 _-- #_ Q1 _- Q3 - R2 # \ * - \ \ R3 # Here, we see that, though Q1Q2Q3 is still non-monotonic, R1R2R3 is ever descending: We thus know that it doesn't contain the extremum. We can then re-subdivide Q1Q2Q3 into two sub-arcs and go on recursively, stopping when we encounter two monotonic subarcs, or when the subarcs become simply too small. We will finally find the vertical extremum. Note that the iterative process of finding an extremum is called `flattening'. e. Computing Profiles Coordinates Once we have the height of each profile, we are able to allocate it in the render pool. The next task is to compute coordinates for each scanline. In the case of segments, the computation is straightforward, using the Euclidean algorithm (also known as Bresenham). However, for Bézier arcs, the job is a little more complicated. We assume that all Béziers that are part of a profile are the result of flattening the curve, which means that they are all y-monotonic (ascending or descending, and never flat). We now have to compute the intersections of arcs with the profile's scanlines. One way is to use a similar scheme to flattening called `stepping'. Consider this arc, going from P1 to --------------------- P3. Suppose that we need to compute its intersections with the drawn scanlines. As already --------------------- mentioned this can be done directly, but the involved * P2 _---# P3 algorithm is far too slow. ------------- _-- -- _- _/ Instead, it is still possible to ---------/----------- use the decomposition property in / the same recursive way, i.e., \| subdivide the arc into subarcs ------\|-------------- until these get too small to cross \| more than one scanline! \| -----\|--------------- This is very easily done using a \| rasterizer-managed stack of \| subarcs. # P1 f. Sweeping and Sorting the Spans Once all our profiles have been computed, we begin the sweep to build (and fill) the spans. As both the TrueType and Type 1 specifications use the winding fill rule (but with opposite directions), we place, on each scanline, the present profiles in two separate lists. One list, called the `left' one, only contains ascending profiles, while the other `right' list contains the descending profiles. As each glyph is made of closed curves, a simple geometric property ensures that the two lists contain the same number of elements. Creating spans is thus straightforward: 1. We sort each list in increasing horizontal order. 2. We pair each value of the left list with its corresponding value in the right list. / / \| \| For example, we have here / / \| \| four profiles. Two of >/ / \| \| \| them are ascending (1 & 1// / ^ \| \| \| 2 3), while the two others // // 3\| \| \| v are descending (2 & 4). / //4 \| \| \| On the given scanline, a / /< \| \| the left list is (1,3), - - - ----- - - - - --- - - y - and the right one is / / b c\| \|d (4,2) (sorted). There are then two spans, joining 1 to 4 (i.e. a-b) and 3 to 2 (i.e. c-d)! Sorting doesn't necessarily take much time, as in 99 cases out of 100, the lists' order is kept from one scanline to the next. We can thus implement it with two simple singly-linked lists, sorted by a classic bubble-sort, which takes a minimum amount of time when the lists are already sorted. A previous version of the rasterizer used more elaborate structures, like arrays to perform `faster' sorting. It turned out that this old scheme is not faster than the one described above. Once the spans have been `created', we can simply draw them in the target bitmap. ------------------------------------------------------------------------ Copyright (C) 2003-2022 by David Turner, Robert Wilhelm, and Werner Lemberg.

<code><a href="ft2-base_interface.html#ft_open_face">FT_Open_Face</a></code>. This means that if no font driver is capable of handling the raw compressed file, the library will try to open a bzip2 compressed stream from it and re-open the face with it.</p> <p>The stream implementation is very basic and resets the decompression process each time seeking backwards is needed within the stream, which significantly undermines the performance.</p> <p>This section contains the declaration of Bzip2-specific functions.</p> <h2 id="ft_stream_openbzip2">FT_Stream_OpenBzip2<a class="headerlink" href="#ft_stream_openbzip2" title="Permanent link">¶</a></h2> <p>Defined in FT_BZIP2_H (freetype/ftbzip2.h).</p> <div class = "codehilite"><pre><code> FT_EXPORT( <a href="ft2-basic_types.html#ft_error">FT_Error</a> ) <b>FT_Stream_OpenBzip2</b>( <a href="ft2-system_interface.html#ft_stream">FT_Stream</a> stream, <a href="ft2-system_interface.html#ft_stream">FT_Stream</a> source ); </code></pre></div> <p>Open a new stream to parse bzip2-compressed font files.

Sub-System<a class="headerlink" href="#cache-sub-system" title="Permanent link">¶</a></h1> <h2 id="synopsis">Synopsis<a class="headerlink" href="#synopsis" title="Permanent link">¶</a></h2> <p>This section describes the FreeType 2 cache sub-system, which is used to limit the number of concurrently opened <code><a href="ft2-base_interface.html#ft_face">FT_Face</a></code> and <code><a href="ft2-base_interface.html#ft_size">FT_Size</a></code> objects, as well as caching information like character maps and glyph images while limiting their maximum memory usage.</p> <p>Note that all types and functions begin with the <code>FTC_</code> prefix.</p> <p>The cache is highly portable and thus doesn't know anything about the fonts installed on your system, or how to access them. This implies the following scheme:</p> <p>First, available or installed font faces are uniquely identified by <code><a href="ft2-cache_subsystem.html#ftc_faceid">FTC_FaceID</a></code> values, provided to the cache by the client. Note that the cache only stores and compares these values, and doesn't try to interpret them in any way.</p> <p>Second, the cache calls, only when needed, a client-provided function to convert an <code><a href="ft2-cache_subsystem.html#ftc_faceid">FTC_FaceID</a></code> into a new <code><a href="ft2-base_interface.html#ft_face">FT_Face</a></code> object. The latter is then completely managed by the cache, including its termination through <code><a href="ft2-base_interface.html#ft_done_face">FT_Done_Face</a></code>. To monitor termination of face objects, the finalizer callback in the <code>generic</code> field of the <code><a href="ft2-base_interface.html#ft_face">FT_Face</a></code> object can be used, which might also be used to store the <code><a href="ft2-cache_subsystem.html#ftc_faceid">FTC_FaceID</a></code> of the face.</p> <p>Clients are free to map face IDs to anything else. The most simple usage is to associate them to a (pathname,face_index) pair that is used to call <code><a href="ft2-base_interface.html#ft_new_face">FT_New_Face</a></code>. However, more complex schemes are also possible.</p> <p>Note that for the cache to work correctly, the face ID values must be <strong>persistent</strong>, which means that the contents they point to should not change at runtime, or that their value should not become invalid.</p> <p>If this is unavoidable (e.g., when a font is uninstalled at runtime), you should call <code><a href="ft2-cache_subsystem.html#ftc_manager_removefaceid">FTC_Manager_RemoveFaceID</a></code> as soon as possible, to let the cache get rid of any references to the old <code><a href="ft2-cache_subsystem.html#ftc_faceid">FTC_FaceID</a></code> it may keep internally. Failure to do so will lead to incorrect behaviour or even crashes.</p> <p>To use the cache, start with calling <code><a href="ft2-cache_subsystem.html#ftc_manager_new">FTC_Manager_New</a></code> to create a new <code><a href="ft2-cache_subsystem.html#ftc_manager">FTC_Manager</a></code> object, which models a single cache instance. You can then look up <code><a href="ft2-base_interface.html#ft_face">FT_Face</a></code> and <code><a href="ft2-base_interface.html#ft_size">FT_Size</a></code> objects with <code><a href="ft2-cache_subsystem.html#ftc_manager_lookupface">FTC_Manager_LookupFace</a></code> and <code><a href="ft2-cache_subsystem.html#ftc_manager_lookupsize">FTC_Manager_LookupSize</a></code>, respectively.</p> <p>If you want to use the charmap caching, call <code><a href="ft2-cache_subsystem.html#ftc_cmapcache_new">FTC_CMapCache_New</a></code>, then later use <code><a href="ft2-cache_subsystem.html#ftc_cmapcache_lookup">FTC_CMapCache_Lookup</a></code> to perform the equivalent of <code><a href="ft2-base_interface.html#ft_get_char_index">FT_Get_Char_Index</a></code>, only much faster.</p> <p>If you want to use the <code><a href="ft2-glyph_management.html#ft_glyph">FT_Glyph</a></code> caching, call <code><a href="ft2-cache_subsystem.html#ftc_imagecache_new">FTC_ImageCache_New</a></code>, then later use <code><a href="ft2-cache_subsystem.html#ftc_imagecache_lookup">FTC_ImageCache_Lookup</a></code> to retrieve the corresponding <code><a href="ft2-glyph_management.html#ft_glyph">FT_Glyph</a></code> objects from the cache.</p> <p>If you need lots of small bitmaps, it is much more memory efficient to call <code><a href="ft2-cache_subsystem.html#ftc_sbitcache_new">FTC_SBitCache_New</a></code> followed by <code><a href="ft2-cache_subsystem.html#ftc_sbitcache_lookup">FTC_SBitCache_Lookup</a></code>. This returns <code><a href="ft2-cache_subsystem.html#ftc_sbitrec">FTC_SBitRec</a></code> structures, which are used to store small bitmaps directly. (A small bitmap is one whose metrics and dimensions all fit into 8-bit integers).</p> <p>We hope to also provide a kerning cache in the near future.</p> <h2 id="ftc_manager">FTC_Manager<a class="headerlink" href="#ftc_manager" title="Permanent link">¶</a></h2> <p>Defined in FT_CACHE_H (freetype/ftcache.h).</p> <div class = "codehilite"><pre><code> <span class="keyword">typedef</span> <span class="keyword">struct</span> FTC_ManagerRec_* <b>FTC_Manager</b>; </code></pre></div> <p>This object corresponds to one instance of the cache-subsystem.

href="#synopsis" title="Permanent link">¶</a></h2> <p>While FreeType's CFF driver doesn't expose API functions by itself, it is possible to control its behaviour with <code><a href="ft2-module_management.html#ft_property_set">FT_Property_Set</a></code> and <code><a href="ft2-module_management.html#ft_property_get">FT_Property_Get</a></code>.</p> <p>The CFF driver's module name is ‘cff’.</p> <p>Available properties are <code><a href="ft2-properties.html#hinting-engine">hinting-engine</a></code>, <code><a href="ft2-properties.html#no-stem-darkening">no-stem-darkening</a></code>, <code><a href="ft2-properties.html#darkening-parameters">darkening-parameters</a></code>, and <code><a href="ft2-properties.html#random-seed">random-seed</a></code>, as documented in the ‘<a href="ft2-properties.html#properties">Driver properties</a>’ section.</p> <p><strong>Hinting and anti-aliasing principles of the new engine</strong></p> <p>The rasterizer is positioning horizontal features (e.g., ascender height & x-height, or crossbars) on the pixel grid and minimizing the amount of anti-aliasing applied to them, while placing vertical features (vertical stems) on the pixel grid without hinting, thus representing the stem position and weight accurately. Sometimes the vertical stems may be only partially black. In this context, ‘anti-aliasing’ means that stems are not positioned exactly on pixel borders, causing a fuzzy appearance.</p> <p>There are two principles behind this approach.</p> <p>1) No hinting in the horizontal direction: Unlike ‘superhinted’ TrueType, which changes glyph widths to accommodate regular inter-glyph spacing, Adobe's approach is ‘faithful to the design’ in representing both the glyph width and the inter-glyph spacing designed for the font. This makes the screen display as close as it can be to the result one would get with infinite resolution, while preserving what is considered the key characteristics of each glyph. Note that the distances between unhinted and grid-fitted positions at small sizes are comparable to kerning values and thus would be noticeable (and distracting) while reading if hinting were applied.</p> <p>One of the reasons to not hint horizontally is anti-aliasing for LCD screens: The pixel geometry of modern displays supplies three vertical subpixels as the eye moves horizontally across each visible pixel. On devices where we can be certain this characteristic is present a rasterizer can take advantage of the subpixels to add increments of weight. In Western writing systems this turns out to be the more critical direction anyway; the weights and spacing of vertical stems (see above) are central to Armenian, Cyrillic, Greek, and Latin type designs. Even when the rasterizer uses greyscale anti-aliasing instead of color (a necessary compromise when one doesn't know the screen characteristics), the unhinted vertical features preserve the design's weight and spacing much better than aliased type would.</p> <p>2) Alignment in the vertical direction: Weights and spacing along the y axis are less critical; what is much more important is the visual alignment of related features (like cap-height and x-height). The sense of alignment for these is enhanced by the sharpness of grid-fit edges, while the cruder vertical resolution (full pixels instead of ⅓ pixels) is less of a problem.</p> <p>On the technical side, horizontal alignment zones for ascender, x-height, and other important height values (traditionally called ‘blue zones’) as defined in the font are positioned independently, each being rounded to the nearest pixel edge, taking care of overshoot suppression at small sizes, stem darkening, and scaling.</p> <p>Hstems (this is, hint values defined in the font to help align horizontal features) that fall within a blue zone are said to be ‘captured’ and are aligned to that zone. Uncaptured stems are moved in one of four ways, top edge up or down, bottom edge up or down.

The first argument of the <code>FT_ERROR_DEF_</code> macro is the error label; by default, the prefix <code>FT_Err_</code> gets added so that you get error names like <code>FT_Err_Cannot_Open_Resource</code>. The second argument is the error code, and the last argument an error string, which is not used by FreeType.</p> <p>Within your application you should <strong>only</strong> use error names and <strong>never</strong> its numeric values! The latter might (and actually do) change in forthcoming FreeType versions.</p> <p>Macro <code>FT_NOERRORDEF_</code> defines <code>FT_Err_Ok</code>, which is always zero.

class="headerlink" href="#synopsis" title="Permanent link">¶</a></h2> <p>The header file <code>fterrors.h</code> (which is automatically included by <code>freetype.h</code> defines the handling of FreeType's enumeration constants. It can also be used to generate error message strings with a small macro trick explained below.</p> <p><strong>Error Formats</strong></p> <p>The configuration macro <code>FT_CONFIG_OPTION_USE_MODULE_ERRORS</code> can be defined in <code>ftoption.h</code> in order to make the higher byte indicate the module where the error has happened (this is not compatible with standard builds of FreeType 2, however). See the file <code>ftmoderr.h</code> for more details.</p> <p><strong>Error Message Strings</strong></p> <p>Error definitions are set up with special macros that allow client applications to build a table of error message strings. The strings are not included in a normal build of FreeType 2 to save space (most client applications do not use them).</p> <p>To do so, you have to define the following macros before including this file. <div class="highlight"><pre><span></span><code> FT_ERROR_START_LIST </code></pre></div></p> <p>This macro is called before anything else to define the start of the error list. It is followed by several <code>FT_ERROR_DEF</code> calls. <div class="highlight"><pre><span></span><code> FT_ERROR_DEF( e, v, s ) </code></pre></div></p> <p>This macro is called to define one single error. ‘e’ is the error code identifier (e.g., <code>Invalid_Argument</code>), ‘v’ is the error's numerical value, and ‘s’ is the corresponding error string. <div class="highlight"><pre><span></span><code> FT_ERROR_END_LIST </code></pre></div></p> <p>This macro ends the list.</p> <p>Additionally, you have to undefine <code>FTERRORS_H_</code> before #including this file.</p> <p>Here is a simple example. <div class="highlight"><pre><span></span><code> #undef FTERRORS_H_ #define FT_ERRORDEF( e, v, s ) { e, s }, #define FT_ERROR_START_LIST { #define FT_ERROR_END_LIST { 0, NULL } }; const struct { int err_code; const char* err_msg; } ft_errors[] = #include <freetype/fterrors.h> </code></pre></div></p> <p>An alternative to using an array is a switch statement. <div class="highlight"><pre><span></span><code> #undef FTERRORS_H_ #define FT_ERROR_START_LIST switch ( error_code ) { #define FT_ERRORDEF( e, v, s ) case v: return s; #define FT_ERROR_END_LIST } </code></pre></div></p> <p>If you use <code>FT_CONFIG_OPTION_USE_MODULE_ERRORS</code>, <code>error_code</code> should be replaced with <code>FT_ERROR_BASE(error_code)</code> in the last example.</p> <h2 id="ft_error_string">FT_Error_String<a class="headerlink" href="#ft_error_string" title="Permanent link">¶</a></h2> <p>Defined in FT_ERRORS_H (freetype/fterrors.h).</p> <div class = "codehilite"><pre><code> FT_EXPORT( <span class="keyword">const</span> <span class="keyword">char</span>* ) <b>FT_Error_String</b>( <a href="ft2-basic_types.html#ft_error">FT_Error</a> error_code );

Variation Sequences<a class="headerlink" href="#unicode-variation-sequences" title="Permanent link">¶</a></h1> <h2 id="synopsis">Synopsis<a class="headerlink" href="#synopsis" title="Permanent link">¶</a></h2> <p>Many characters, especially for CJK scripts, have variant forms. They are a sort of grey area somewhere between being totally irrelevant and semantically distinct; for this reason, the Unicode consortium decided to introduce Variation Sequences (VS), consisting of a Unicode base character and a variation selector instead of further extending the already huge number of characters.</p> <p>Unicode maintains two different sets, namely ‘Standardized Variation Sequences’ and registered ‘Ideographic Variation Sequences’ (IVS), collected in the ‘Ideographic Variation Database’ (IVD).</p> <p><a href="https://unicode.org/Public/UCD/latest/ucd/StandardizedVariants.txt">https://unicode.org/Public/UCD/latest/ucd/StandardizedVariants.txt</a> <a href="https://unicode.org/reports/tr37/">https://unicode.org/reports/tr37/</a> <a href="https://unicode.org/ivd/">https://unicode.org/ivd/</a></p> <p>To date (January 2017), the character with the most ideographic variations is U+9089, having 32 such IVS.</p> <p>Three Mongolian Variation Selectors have the values U+180B-U+180D; 256 generic Variation Selectors are encoded in the ranges U+FE00-U+FE0F and U+E0100-U+E01EF. IVS currently use Variation Selectors from the range U+E0100-U+E01EF only.</p> <p>A VS consists of the base character value followed by a single Variation Selector. For example, to get the first variation of U+9089, you have to write the character sequence <code>U+9089 U+E0100</code>.</p> <p>Adobe and MS decided to support both standardized and ideographic VS with a new cmap subtable (format 14). It is an odd subtable because it is not a mapping of input code points to glyphs, but contains lists of all variations supported by the font.</p> <p>A variation may be either ‘default’ or ‘non-default’ for a given font. A default variation is the one you will get for that code point if you look it up in the standard Unicode cmap. A non-default variation is a different glyph.</p> <h2 id="ft_face_getcharvariantindex">FT_Face_GetCharVariantIndex<a class="headerlink" href="#ft_face_getcharvariantindex" title="Permanent link">¶</a></h2> <p>Defined in FT_FREETYPE_H (freetype/freetype.h).</p> <div class = "codehilite"><pre><code> FT_EXPORT( <a href="ft2-basic_types.html#ft_uint">FT_UInt</a> ) <b>FT_Face_GetCharVariantIndex</b>( <a href="ft2-base_interface.html#ft_face">FT_Face</a> face, <a href="ft2-basic_types.html#ft_ulong">FT_ULong</a> charcode, <a href="ft2-basic_types.html#ft_ulong">FT_ULong</a> variantSelector ); </code></pre></div> <p>Return the glyph index of a given character code as modified by the variation selector.</p> <h4>input</h4> <table class="fields"> <tr><td class="val" id="face">face</td><td class="desc"> <p>A handle to the source face object.</p> </td></tr> <tr><td class="val" id="charcode">charcode</td><td class="desc"> <p>The character code point in Unicode.</p> </td></tr> <tr><td class="val" id="variantselector">variantSelector</td><td class="desc"> <p>The Unicode code point of the variation selector.</p> </td></tr> </table> <h4>return</h4> <p>The glyph index. 0 means either ‘undefined character code’, or ‘undefined selector code’, or ‘no variation selector cmap subtable’, or ‘current CharMap is not Unicode’.</p> <h4>note</h4> <p>If you use FreeType to manipulate the contents of font files directly, be aware that the glyph index returned by this function doesn't always correspond to the internal indices used within the file.

section contains various functions used to perform so-called ‘incremental’ glyph loading. This is a mode where all glyphs loaded from a given <code><a href="ft2-base_interface.html#ft_face">FT_Face</a></code> are provided by the client application.</p> <p>Apart from that, all other tables are loaded normally from the font file.

Subpixel Rendering</p> <hr /> <h1 id="subpixel-rendering">Subpixel Rendering<a class="headerlink" href="#subpixel-rendering" title="Permanent link">¶</a></h1> <h2 id="synopsis">Synopsis<a class="headerlink" href="#synopsis" title="Permanent link">¶</a></h2> <p>FreeType provides two alternative subpixel rendering technologies. Should you define <code>FT_CONFIG_OPTION_SUBPIXEL_RENDERING</code> in your <code>ftoption.h</code> file, this enables ClearType-style rendering. Otherwise, Harmony LCD rendering is enabled. These technologies are controlled differently and API described below, although always available, performs its function when appropriate method is enabled and does nothing otherwise.</p> <p>ClearType-style LCD rendering exploits the color-striped structure of LCD pixels, increasing the available resolution in the direction of the stripe (usually horizontal RGB) by a factor of 3. Using the subpixel coverages unfiltered can create severe color fringes especially when rendering thin features. Indeed, to produce black-on-white text, the nearby color subpixels must be dimmed evenly. Therefore, an equalizing 5-tap FIR filter should be applied to subpixel coverages regardless of pixel boundaries and should have these properties:</p> <ol> <li> <p>It should be symmetrical, like { a, b, c, b, a }, to avoid any shifts in appearance.</p> </li> <li> <p>It should be color-balanced, meaning a + b = c, to reduce color fringes by distributing the computed coverage for one subpixel to all subpixels equally.</p> </li> <li> <p>It should be normalized, meaning 2a + 2b + c = 1.0 to maintain overall brightness.</p> </li> </ol> <p>Boxy 3-tap filter {0, ⅓, ⅓, ⅓, 0} is sharper but is less forgiving of non-ideal gamma curves of a screen (and viewing angles), beveled filters are fuzzier but more tolerant.</p> <p>Use the <code><a href="ft2-lcd_rendering.html#ft_library_setlcdfilter">FT_Library_SetLcdFilter</a></code> or <code><a href="ft2-lcd_rendering.html#ft_library_setlcdfilterweights">FT_Library_SetLcdFilterWeights</a></code> API to specify a low-pass filter, which is then applied to subpixel-rendered bitmaps generated through <code><a href="ft2-base_interface.html#ft_render_glyph">FT_Render_Glyph</a></code>.</p> <p>Harmony LCD rendering is suitable to panels with any regular subpixel structure, not just monitors with 3 color striped subpixels, as long as the color subpixels have fixed positions relative to the pixel center. In this case, each color channel can be rendered separately after shifting the outline opposite to the subpixel shift so that the coverage maps are aligned. This method is immune to color fringes because the shifts do not change integral coverage.</p> <p>The subpixel geometry must be specified by xy-coordinates for each subpixel. By convention they may come in the RGB order: {{-⅓, 0}, {0, 0}, {⅓, 0}} for standard RGB striped panel or {{-⅙, ¼}, {-⅙, -¼}, {⅓, 0}} for a certain PenTile panel.</p> <p>Use the <code><a href="ft2-lcd_rendering.html#ft_library_setlcdgeometry">FT_Library_SetLcdGeometry</a></code> API to specify subpixel positions. If one follows the RGB order convention, the same order applies to the resulting <code><a href="ft2-basic_types.html#ft_pixel_mode">FT_PIXEL_MODE_LCD</a></code> and <code><a href="ft2-basic_types.html#ft_pixel_mode">FT_PIXEL_MODE_LCD_V</a></code> bitmaps. Note, however, that the coordinate frame for the latter must be rotated clockwise. Harmony with default LCD geometry is equivalent to ClearType with light filter.</p> <p>As a result of ClearType filtering or Harmony shifts, the resulting dimensions of LCD bitmaps can be slightly wider or taller than the dimensions the original outline with regard to the pixel grid. For example, for <code><a href="ft2-base_interface.html#ft_render_mode">FT_RENDER_MODE_LCD</a></code>, the filter adds 2 subpixels to the left, and 2 subpixels to the right. The bitmap offset values are adjusted accordingly, so clients shouldn't need to modify their layout and glyph positioning code when enabling the filter.</p> <p>The ClearType and Harmony rendering is applicable to glyph bitmaps rendered through <code><a href="ft2-base_interface.html#ft_render_glyph">FT_Render_Glyph</a></code>, <code><a href="ft2-base_interface.html#ft_load_glyph">FT_Load_Glyph</a></code>, <code><a href="ft2-base_interface.html#ft_load_char">FT_Load_Char</a></code>, and <code><a href="ft2-glyph_management.html#ft_glyph_to_bitmap">FT_Glyph_To_Bitmap</a></code>, when <code><a href="ft2-base_interface.html#ft_render_mode">FT_RENDER_MODE_LCD</a></code> or <code><a href="ft2-base_interface.html#ft_render_mode">FT_RENDER_MODE_LCD_V</a></code> is specified. This API does not control <code><a href="ft2-outline_processing.html#ft_outline_render">FT_Outline_Render</a></code> and <code><a href="ft2-outline_processing.html#ft_outline_get_bitmap">FT_Outline_Get_Bitmap</a></code>.</p> <p>The described algorithms can completely remove color artefacts when combined with gamma-corrected alpha blending in linear space. Each of the 3 alpha values (subpixels) must by independently used to blend one color channel. That is, red alpha blends the red channel of the text color with the red channel of the background pixel.</p> <h2 id="ft_lcdfilter">FT_LcdFilter<a class="headerlink" href="#ft_lcdfilter" title="Permanent link">¶</a></h2> <p>Defined in FT_LCD_FILTER_H (freetype/ftlcdfil.h).</p> <div class = "codehilite"><pre><code> <span class="keyword">typedef</span> <span class="keyword">enum</span> FT_LcdFilter_ { <a href="ft2-lcd_rendering.html#ft_lcd_filter_none">FT_LCD_FILTER_NONE</a> = 0, <a href="ft2-lcd_rendering.html#ft_lcd_filter_default">FT_LCD_FILTER_DEFAULT</a> = 1, <a href="ft2-lcd_rendering.html#ft_lcd_filter_light">FT_LCD_FILTER_LIGHT</a> = 2, <a href="ft2-lcd_rendering.html#ft_lcd_filter_legacy1">FT_LCD_FILTER_LEGACY1</a> = 3, <a href="ft2-lcd_rendering.html#ft_lcd_filter_legacy">FT_LCD_FILTER_LEGACY</a> = 16, FT_LCD_FILTER_MAX /* do not remove / } <b>FT_LcdFilter</b>; </code></pre></div> <p>A list of values to identify various types of LCD filters.</p> <h4>values</h4> <table class="fields"> <tr><td class="val" id="ft_lcd_filter_none">FT_LCD_FILTER_NONE</td><td class="desc"> <p>Do not perform filtering.

This means that if no font driver is capable of handling the raw compressed file, the library will try to open a LZW stream from it and re-open the face with it.</p> <p>The stream implementation is very basic and resets the decompression process each time seeking backwards is needed within the stream, which significantly undermines the performance.</p> <p>This section contains the declaration of LZW-specific functions.</p> <h2 id="ft_stream_openlzw">FT_Stream_OpenLZW<a class="headerlink" href="#ft_stream_openlzw" title="Permanent link">¶</a></h2> <p>Defined in FT_LZW_H (freetype/ftlzw.h).</p> <div class = "codehilite"><pre><code> FT_EXPORT( <a href="ft2-basic_types.html#ft_error">FT_Error</a> ) <b>FT_Stream_OpenLZW</b>( <a href="ft2-system_interface.html#ft_stream">FT_Stream</a> stream, <a href="ft2-system_interface.html#ft_stream">FT_Stream</a> source ); </code></pre></div> <p>Open a new stream to parse LZW-compressed font files.

This flag is ignored by the scan converter.</p> </td></tr> <tr><td class="val" id="ft_outline_ignore_dropouts">FT_OUTLINE_IGNORE_DROPOUTS</td><td class="desc"> <p>By default, the scan converter will try to detect drop-outs in an outline and correct the glyph bitmap to ensure consistent shape continuity. If set, this flag hints the scan-line converter to ignore such cases. See below for more information.</p> </td></tr> <tr><td class="val" id="ft_outline_smart_dropouts">FT_OUTLINE_SMART_DROPOUTS</td><td class="desc"> <p>Select smart dropout control. If unset, use simple dropout control. Ignored if <code><a href="ft2-outline_processing.html#ft_outline_xxx">FT_OUTLINE_IGNORE_DROPOUTS</a></code> is set. See below for more information.</p> </td></tr> <tr><td class="val" id="ft_outline_include_stubs">FT_OUTLINE_INCLUDE_STUBS</td><td class="desc"> <p>If set, turn pixels on for ‘stubs’, otherwise exclude them.

This flag should <em>not</em> be set for well designed glyphs without overlaps because it quadruples the rendering time.</p> </td></tr> <tr><td class="val" id="ft_outline_high_precision">FT_OUTLINE_HIGH_PRECISION</td><td class="desc"> <p>This flag indicates that the scan-line converter should try to convert this outline to bitmaps with the highest possible quality. It is typically set for small character sizes. Note that this is only a hint that might be completely ignored by a given scan-converter.</p> </td></tr> <tr><td class="val" id="ft_outline_single_pass">FT_OUTLINE_SINGLE_PASS</td><td class="desc"> <p>This flag is set to force a given scan-converter to only use a single pass over the outline to render a bitmap glyph image.

<p>FreeType is a library that provides access to glyphs in font files. It scales the glyph images and their metrics to a requested size, and it rasterizes the glyph images to produce pixel or subpixel alpha coverage bitmaps.</p> <p>Note that FreeType is <em>not</em> a text layout engine. You have to use higher-level libraries like HarfBuzz, Pango, or ICU for that.</p> <p>Note also that FreeType does <em>not</em> perform alpha blending or compositing the resulting bitmaps or pixmaps by itself. Use your favourite graphics library (for example, Cairo or Skia) to further process FreeType's output.</p> </article> </div> </div> </main> <footer class="md-footer"> <nav class="md-footer__inner md-grid" aria-label="Footer"> <a href="ft2-index.html" class="md-footer__link md-footer__link--prev" aria-label="Previous: Index" rel="prev"> <div class="md-footer__button md-icon"> <svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 24 24"><path d="M20 11v2H8l5.5 5.5-1.42 1.42L4.16 12l7.92-7.92L13.5 5.5 8 11h12z"/></svg> </div> <div class="md-footer__title"> <div class="md-ellipsis"> <span class="md-footer__direction"> Previous </span> Index </div> </div> </a> <a href="ft2-header_inclusion.html" class="md-footer__link md-footer__link--next" aria-label="Next: FreeType's header inclusion scheme" rel="next"> <div class="md-footer__title"> <div class="md-ellipsis"> <span class="md-footer__direction"> Next </span> FreeType's header inclusion scheme </div> </div> <div class="md-footer__button md-icon"> <svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 24 24"><path d="M4 11v2h12l-5.5 5.5 1.42 1.42L19.84 12l-7.92-7.92L10.5 5.5 16 11H4z"/></svg> </div> </a> </nav> <div class="md-footer-meta md-typeset"> <div class="md-footer-meta__inner md-grid"> <div class="md-footer-copyright"> <div class="md-footer-copyright__highlight"> Copyright 2022 <a href = "https://www.freetype.org/license.html">The FreeType Project</a>. </div> Made with <a href="https://squidfunk.github.io/mkdocs-material/" target="_blank" rel="noopener"> Material for MkDocs </a> </div> </div> </div> </footer> </div> <div class="md-dialog" data-md-component="dialog"> <div class="md-dialog__inner md-typeset"></div> </div> <script id="__config" type="application/json">{"base": ".", "features": [], "translations": {"clipboard.copy": "Copy to clipboard", "clipboard.copied": "Copied to clipboard", "search.config.lang": "en", "search.config.pipeline": "trimmer, stopWordFilter", "search.config.separator": "[\\s\\-]+", "search.placeholder": "Search", "search.result.placeholder": "Type to start searching", "search.result.none": "No matching documents", "search.result.one": "1 matching document", "search.result.other": "# matching documents", "search.result.more.one": "1 more on this page", "search.result.more.other": "# more on this page", "search.result.term.missing": "Missing", "select.version.title": "Select version"}, "search": "assets/javascripts/workers/search.477d984a.min.js", "version": null}</script> <script src="assets/javascripts/bundle.82b56eb2.min.js"></script> <script src="javascripts/extra.js"></script> </body> </html>	whupdup/frame	real/third_party/freetype-2.12.0/docs/reference/ft2-preamble.html	HTML	gpl-3.0	27,303

If this configuration macro isn't defined, ‘hinting-engine’ does nothing.</p> <p>The same holds for the Type 1 and CID modules if compiled with <code>T1_CONFIG_OPTION_OLD_ENGINE</code>.</p> <p>For the ‘cff’ module, the default engine is ‘adobe’. For both the ‘type1’ and ‘t1cid’ modules, the default engine is ‘adobe’, too.</p> <h4>note</h4> <p>This property can be used with <code><a href="ft2-module_management.html#ft_property_get">FT_Property_Get</a></code> also.</p> <p>This property can be set via the <code>FREETYPE_PROPERTIES</code> environment variable (using values ‘adobe’ or ‘freetype’).</p> <h4>example</h4> <p>The following example code demonstrates how to select Adobe's hinting engine for the ‘cff’ module (omitting the error handling). <div class="highlight"><pre><span></span><code> FT_Library library; FT_UInt hinting_engine = FT_HINTING_ADOBE; FT_Init_FreeType( &library ); FT_Property_Set( library, "cff", "hinting-engine", &hinting_engine ); </code></pre></div></p> <h4>since</h4> <p>2.4.12 (for ‘cff’ module)</p> <p>2.9 (for ‘type1’ and ‘t1cid’ modules)</p> <hr> <h2 id="no-stem-darkening">no-stem-darkening<a class="headerlink" href="#no-stem-darkening" title="Permanent link">¶</a></h2> <p>All glyphs that pass through the auto-hinter will be emboldened unless this property is set to TRUE. The same is true for the CFF, Type 1, and CID font modules if the ‘Adobe’ engine is selected (which is the default).</p> <p>Stem darkening emboldens glyphs at smaller sizes to make them more readable on common low-DPI screens when using linear alpha blending and gamma correction, see <code><a href="ft2-base_interface.html#ft_render_glyph">FT_Render_Glyph</a></code>. When not using linear alpha blending and gamma correction, glyphs will appear heavy and fuzzy!</p> <p>Gamma correction essentially lightens fonts since shades of grey are shifted to higher pixel values (= higher brightness) to match the original intention to the reality of our screens. The side-effect is that glyphs ‘thin out’. Mac OS X and Adobe's proprietary font rendering library implement a counter-measure: stem darkening at smaller sizes where shades of gray dominate. By emboldening a glyph slightly in relation to its pixel size, individual pixels get higher coverage of filled-in outlines and are therefore ‘blacker’. This counteracts the ‘thinning out’ of glyphs, making text remain readable at smaller sizes.</p> <p>For the auto-hinter, stem-darkening is experimental currently and thus switched off by default (this is, <code>no-stem-darkening</code> is set to TRUE by default). Total consistency with the CFF driver is not achieved right now because the emboldening method differs and glyphs must be scaled down on the Y-axis to keep outline points inside their precomputed blue zones. The smaller the size (especially 9ppem and down), the higher the loss of emboldening versus the CFF driver.</p> <p>Note that stem darkening is never applied if <code><a href="ft2-base_interface.html#ft_load_xxx">FT_LOAD_NO_SCALE</a></code> is set.</p> <h4>note</h4> <p>This property can be used with <code><a href="ft2-module_management.html#ft_property_get">FT_Property_Get</a></code> also.</p> <p>This property can be set via the <code>FREETYPE_PROPERTIES</code> environment variable (using values 1 and 0 for ‘on’ and ‘off’, respectively). It can also be set per face using <code><a href="ft2-base_interface.html#ft_face_properties">FT_Face_Properties</a></code> with <code><a href="ft2-parameter_tags.html#ft_param_tag_stem_darkening">FT_PARAM_TAG_STEM_DARKENING</a></code>.</p> <h4>example</h4> <div class="highlight"><pre><span></span><code> FT_Library library; FT_Bool no_stem_darkening = TRUE; FT_Init_FreeType( &library ); FT_Property_Set( library, "cff", "no-stem-darkening", &no_stem_darkening ); </code></pre></div> <h4>since</h4> <p>2.4.12 (for ‘cff’ module)</p> <p>2.6.2 (for ‘autofitter’ module)</p> <p>2.9 (for ‘type1’ and ‘t1cid’ modules)</p> <hr> <h2 id="darkening-parameters">darkening-parameters<a class="headerlink" href="#darkening-parameters" title="Permanent link">¶</a></h2> <p>By default, the Adobe hinting engine, as used by the CFF, Type 1, and CID font drivers, darkens stems as follows (if the <code>no-stem-darkening</code> property isn't set): <div class="highlight"><pre><span></span><code> stem width <= 0.5px: darkening amount = 0.4px stem width = 1px: darkening amount = 0.275px stem width = 1.667px: darkening amount = 0.275px stem width >= 2.333px: darkening amount = 0px </code></pre></div></p> <p>and piecewise linear in-between. At configuration time, these four control points can be set with the macro <code>CFF_CONFIG_OPTION_DARKENING_PARAMETERS</code>; the CFF, Type 1, and CID drivers share these values. At runtime, the control points can be changed using the <code>darkening-parameters</code> property (see the example below that demonstrates this for the Type 1 driver).</p> <p>The x values give the stem width, and the y values the darkening amount. The unit is 1000<sup>th</sup> of pixels.

As a consequence, the version numbers returned by a call to the ‘GETINFO’ bytecode instruction are more convoluted than desired.</p> <p>Here are two tables that try to shed some light on the possible values for the MS rasterizer engine, together with the additional features introduced by it. <div class="highlight"><pre><span></span><code> GETINFO framework version feature ------------------------------------------------------------------- 3 GDI (Win 3.1), v1.0 16-bit, first version TrueImage 33 GDI (Win NT 3.1), v1.5 32-bit HP Laserjet 34 GDI (Win 95) v1.6 font smoothing, new SCANTYPE opcode 35 GDI (Win 98/2000) v1.7 (UN)SCALED_COMPONENT_OFFSET bits in composite glyphs 36 MGDI (Win CE 2) v1.6+ classic ClearType 37 GDI (XP and later), v1.8 ClearType GDI+ old (before Vista) 38 GDI+ old (Vista, Win 7), v1.9 subpixel ClearType, WPF Y-direction ClearType, additional error checking 39 DWrite (before Win 8) v2.0 subpixel ClearType flags in GETINFO opcode, bug fixes 40 GDI+ (after Win 7), v2.1 Y-direction ClearType flag DWrite (Win 8) in GETINFO opcode, Gray ClearType </code></pre></div></p> <p>The ‘version’ field gives a rough orientation only, since some applications provided certain features much earlier (as an example, Microsoft Reader used subpixel and Y-direction ClearType already in Windows 2000). Similarly, updates to a given framework might include improved hinting support. <div class="highlight"><pre><span></span><code> version sampling rendering comment x y x y -------------------------------------------------------------- v1.0 normal normal B/W B/W bi-level v1.6 high high gray gray grayscale v1.8 high normal color-filter B/W (GDI) ClearType v1.9 high high color-filter gray Color ClearType v2.1 high normal gray B/W Gray ClearType v2.1 high high gray gray Gray ClearType </code></pre></div></p> <p>Color and Gray ClearType are the two available variants of ‘Y-direction ClearType’, meaning grayscale rasterization along the Y-direction; the name used in the TrueType specification for this feature is ‘symmetric smoothing’. ‘Classic ClearType’ is the original algorithm used before introducing a modified version in Win XP. Another name for v1.6's grayscale rendering is ‘font smoothing’, and ‘Color ClearType’ is sometimes also called ‘DWrite ClearType’. To differentiate between today's Color ClearType and the earlier ClearType variant with B/W rendering along the vertical axis, the latter is sometimes called ‘GDI ClearType’.</p> <p>‘Normal’ and ‘high’ sampling describe the (virtual) resolution to access the rasterized outline after the hinting process. ‘Normal’ means 1 sample per grid line (i.e., B/W). In the current Microsoft implementation, ‘high’ means an extra virtual resolution of 16x16 (or 16x1) grid lines per pixel for bytecode instructions like ‘MIRP’. After hinting, these 16 grid lines are mapped to 6x5 (or 6x1) grid lines for color filtering if Color ClearType is activated.</p> <p>Note that ‘Gray ClearType’ is essentially the same as v1.6's grayscale rendering. However, the GETINFO instruction handles it differently: v1.6 returns bit 12 (hinting for grayscale), while v2.1 returns bits 13 (hinting for ClearType), 18 (symmetrical smoothing), and 19 (Gray ClearType). Also, this mode respects bits 2 and 3 for the version 1 gasp table exclusively (like Color ClearType), while v1.6 only respects the values of version 0 (bits 0 and 1).</p> <p>Keep in mind that the features of the above interpreter versions might not map exactly to FreeType features or behavior because it is a fundamentally different library with different internals.</p> <hr> <h2 id="interpreter-version">interpreter-version<a class="headerlink" href="#interpreter-version" title="Permanent link">¶</a></h2> <p>Currently, three versions are available, two representing the bytecode interpreter with subpixel hinting support (old ‘Infinality’ code and new stripped-down and higher performance ‘minimal’ code) and one without, respectively. The default is subpixel support if <code>TT_CONFIG_OPTION_SUBPIXEL_HINTING</code> is defined, and no subpixel support otherwise (since it isn't available then).</p> <p>If subpixel hinting is on, many TrueType bytecode instructions behave differently compared to B/W or grayscale rendering (except if ‘native ClearType’ is selected by the font). Microsoft's main idea is to render at a much increased horizontal resolution, then sampling down the created output to subpixel precision. However, many older fonts are not suited to this and must be specially taken care of by applying (hardcoded) tweaks in Microsoft's interpreter.</p> <p>Details on subpixel hinting and some of the necessary tweaks can be found in Greg Hitchcock's whitepaper at ‘<a href="https://www.microsoft.com/typography/cleartype/truetypecleartype.aspx">https://www.microsoft.com/typography/cleartype/truetypecleartype.aspx</a>’. Note that FreeType currently doesn't really ‘subpixel hint’ (6x1, 6x2, or 6x5 supersampling) like discussed in the paper. Depending on the chosen interpreter, it simply ignores instructions on vertical stems to arrive at very similar results.</p> <h4>note</h4> <p>This property can be used with <code><a href="ft2-module_management.html#ft_property_get">FT_Property_Get</a></code> also.</p> <p>This property can be set via the <code>FREETYPE_PROPERTIES</code> environment variable (using values ‘35’, ‘38’, or ‘40’).</p> <h4>example</h4> <p>The following example code demonstrates how to deactivate subpixel hinting (omitting the error handling). <div class="highlight"><pre><span></span><code> FT_Library library; FT_Face face; FT_UInt interpreter_version = TT_INTERPRETER_VERSION_35; FT_Init_FreeType( &library ); FT_Property_Set( library, "truetype", "interpreter-version", &interpreter_version ); </code></pre></div></p> <h4>since</h4> <p>2.5</p> <hr> <h2 id="svg-hooks">svg-hooks<a class="headerlink" href="#svg-hooks" title="Permanent link">¶</a></h2> <p>Set up the interface between FreeType and an extern SVG rendering library like ‘librsvg’.

It was entirely removed from the FreeType 2 sources. This entry is only here for historical reference.</p> <p>Warping only worked in ‘normal’ auto-hinting mode replacing it. The idea of the code was to slightly scale and shift a glyph along the non-hinted dimension (which is usually the horizontal axis) so that as much of its segments were aligned (more or less) to the grid. To find out a glyph's optimal scaling and shifting value, various parameter combinations were tried and scored.</p> <h4>since</h4> <p>2.6</p> <hr> </article> </div> </div> </main> <footer class="md-footer"> <nav class="md-footer__inner md-grid" aria-label="Footer"> <a href="ft2-ot_svg_driver.html" class="md-footer__link md-footer__link--prev" aria-label="Previous: The SVG driver" rel="prev"> <div class="md-footer__button md-icon"> <svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 24 24"><path d="M20 11v2H8l5.5 5.5-1.42 1.42L4.16 12l7.92-7.92L13.5 5.5 8 11h12z"/></svg> </div> <div class="md-footer__title"> <div class="md-ellipsis"> <span class="md-footer__direction"> Previous </span> The SVG driver </div> </div> </a> <a href="ft2-parameter_tags.html" class="md-footer__link md-footer__link--next" aria-label="Next: Parameter Tags" rel="next"> <div class="md-footer__title"> <div class="md-ellipsis"> <span class="md-footer__direction"> Next </span> Parameter Tags </div> </div> <div class="md-footer__button md-icon"> <svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 24 24"><path d="M4 11v2h12l-5.5 5.5 1.42 1.42L19.84 12l-7.92-7.92L10.5 5.5 16 11H4z"/></svg> </div> </a> </nav> <div class="md-footer-meta md-typeset"> <div class="md-footer-meta__inner md-grid"> <div class="md-footer-copyright"> <div class="md-footer-copyright__highlight"> Copyright 2022 <a href = "https://www.freetype.org/license.html">The FreeType Project</a>. </div> Made with <a href="https://squidfunk.github.io/mkdocs-material/" target="_blank" rel="noopener"> Material for MkDocs </a> </div> </div> </div> </footer> </div> <div class="md-dialog" data-md-component="dialog"> <div class="md-dialog__inner md-typeset"></div> </div> <script id="__config" type="application/json">{"base": ".", "features": [], "translations": {"clipboard.copy": "Copy to clipboard", "clipboard.copied": "Copied to clipboard", "search.config.lang": "en", "search.config.pipeline": "trimmer, stopWordFilter", "search.config.separator": "[\\s\\-]+", "search.placeholder": "Search", "search.result.placeholder": "Type to start searching", "search.result.none": "No matching documents", "search.result.one": "1 matching document", "search.result.other": "# matching documents", "search.result.more.one": "1 more on this page", "search.result.more.other": "# more on this page", "search.result.term.missing": "Missing", "select.version.title": "Select version"}, "search": "assets/javascripts/workers/search.477d984a.min.js", "version": null}</script> <script src="assets/javascripts/bundle.82b56eb2.min.js"></script> <script src="javascripts/extra.js"></script> </body> </html>	whupdup/frame	real/third_party/freetype-2.12.0/docs/reference/ft2-properties.html	HTML	gpl-3.0	69,131

title="Permanent link">¶</a></h2> <p>A raster or a rasterizer is a scan converter in charge of producing a pixel coverage bitmap that can be used as an alpha channel when compositing a glyph with a background. FreeType comes with two rasterizers: bilevel <code>raster1</code> and anti-aliased <code>smooth</code> are two separate modules. They are usually called from the high-level <code><a href="ft2-base_interface.html#ft_load_glyph">FT_Load_Glyph</a></code> or <code><a href="ft2-base_interface.html#ft_render_glyph">FT_Render_Glyph</a></code> functions and produce the entire coverage bitmap at once, while staying largely invisible to users.</p> <p>Instead of working with complete coverage bitmaps, it is also possible to intercept consecutive pixel runs on the same scanline with the same coverage, called <em>spans</em>, and process them individually. Only the <code>smooth</code> rasterizer permits this when calling <code><a href="ft2-outline_processing.html#ft_outline_render">FT_Outline_Render</a></code> with <code><a href="ft2-raster.html#ft_raster_params">FT_Raster_Params</a></code> as described below.</p> <p>Working with either complete bitmaps or spans it is important to think of them as colorless coverage objects suitable as alpha channels to blend arbitrary colors with a background. For best results, it is recommended to use gamma correction, too.</p> <p>This section also describes the public API needed to set up alternative <code><a href="ft2-module_management.html#ft_renderer">FT_Renderer</a></code> modules.</p> <h2 id="ft_span">FT_Span<a class="headerlink" href="#ft_span" title="Permanent link">¶</a></h2> <p>Defined in FT_IMAGE_H (freetype/ftimage.h).</p> <div class = "codehilite"><pre><code> <span class="keyword">typedef</span> <span class="keyword">struct</span> FT_Span_ { <span class="keyword">short</span> x; <span class="keyword">unsigned</span> <span class="keyword">short</span> len; <span class="keyword">unsigned</span> <span class="keyword">char</span> coverage; } <b>FT_Span</b>; </code></pre></div> <p>A structure to model a single span of consecutive pixels when rendering an anti-aliased bitmap.</p> <h4>fields</h4> <table class="fields"> <tr><td class="val" id="x">x</td><td class="desc"> <p>The span's horizontal start position.</p> </td></tr> <tr><td class="val" id="len">len</td><td class="desc"> <p>The span's length in pixels.</p> </td></tr> <tr><td class="val" id="coverage">coverage</td><td class="desc"> <p>The span color/coverage, ranging from 0 (background) to 255 (foreground).</p> </td></tr> </table> <h4>note</h4> <p>This structure is used by the span drawing callback type named <code><a href="ft2-raster.html#ft_spanfunc">FT_SpanFunc</a></code> that takes the y coordinate of the span as a parameter.</p> <p>The anti-aliased rasterizer produces coverage values from 0 to 255, this is, from completely transparent to completely opaque.</p> <hr> <h2 id="ft_spanfunc">FT_SpanFunc<a class="headerlink" href="#ft_spanfunc" title="Permanent link">¶</a></h2> <p>Defined in FT_IMAGE_H (freetype/ftimage.h).</p> <div class = "codehilite"><pre><code> <span class="keyword">typedef</span> <span class="keyword">void</span> (<b>FT_SpanFunc</b>)( <span class="keyword">int</span> y, <span class="keyword">int</span> count, <span class="keyword">const</span> <a href="ft2-raster.html#ft_span">FT_Span</a> spans, <span class="keyword">void</span>* user ); #<span class="keyword">define</span> FT_Raster_Span_Func <b>FT_SpanFunc</b> </code></pre></div> <p>A function used as a call-back by the anti-aliased renderer in order to let client applications draw themselves the pixel spans on each scan line.</p> <h4>input</h4> <table class="fields"> <tr><td class="val" id="y">y</td><td class="desc"> <p>The scanline's upward y coordinate.</p> </td></tr> <tr><td class="val" id="count">count</td><td class="desc"> <p>The number of spans to draw on this scanline.</p> </td></tr> <tr><td class="val" id="spans">spans</td><td class="desc"> <p>A table of <code>count</code> spans to draw on the scanline.</p> </td></tr> <tr><td class="val" id="user">user</td><td class="desc"> <p>User-supplied data that is passed to the callback.</p> </td></tr> </table> <h4>note</h4> <p>This callback allows client applications to directly render the spans of the anti-aliased bitmap to any kind of surfaces.</p> <p>This can be used to write anti-aliased outlines directly to a given background bitmap using alpha compositing.

By continuing to use, modify, or distribute this file you # indicate that you have read the license and understand and accept it # fully. # # # The following will (1) create a build directory, and (2) change into it and # call cmake to configure the build with default parameters as a static # library. See # # https://cmake.org/cmake/help/latest/variable/CMAKE_BUILD_TYPE.html # # for information about debug or release builds, for example # # cmake -B build -D CMAKE_BUILD_TYPE=Release # # # For a dynamic library, use # # cmake -B build -D BUILD_SHARED_LIBS=true -D CMAKE_BUILD_TYPE=Release # # For a framework on OS X, use # # cmake -E chdir build cmake -G Xcode -D BUILD_FRAMEWORK:BOOL=true .. # # For an iOS static library, use # # cmake -E chdir build cmake -G Xcode -D IOS_PLATFORM=OS .. # # or # # cmake -E chdir build cmake -G Xcode -D IOS_PLATFORM=SIMULATOR .. # # or # # cmake -E chdir build cmake -G Xcode -D IOS_PLATFORM=SIMULATOR64 .. # # # Finally, build the project with # # cmake --build build # # Install it with # # (sudo) cmake --build build --target install # # A binary distribution can be made with # # cmake --build build --config Release --target package # # Please refer to the cmake manual for further options, in particular, how # to modify compilation and linking parameters. # # Some notes. # # - `cmake' creates configuration files in # # <build-directory>/include/freetype/config # # which should be further modified if necessary. # # - You can use `cmake' directly on a freshly cloned FreeType git # repository. # # - `CMakeLists.txt' is provided as-is since it is normally not used by the # developer team. # # - Set the `FT_REQUIRE_ZLIB', `FT_REQUIRE_BZIP2', `FT_REQUIRE_PNG', # `FT_REQUIRE_HARFBUZZ', and `FT_REQUIRE_BROTLI' CMake variables to `ON' # or `TRUE' to force using a dependency. Leave a variable undefined # (which is the default) to use the dependency only if it is available. # Example: # # cmake -B build -D FT_REQUIRE_ZLIB=TRUE \ # -D FT_REQUIRE_BZIP2=TRUE \ # -D FT_REQUIRE_PNG=TRUE \ # -D FT_REQUIRE_HARFBUZZ=TRUE \ # -D FT_REQUIRE_BROTLI=TRUE [...] # # - Set `FT_DISABLE_XXX=TRUE' to disable a dependency completely (where # `XXX' is a CMake package name like `BZip2'). Example for disabling all # dependencies: # # cmake -B build -D FT_DISABLE_ZLIB=TRUE \ # -D FT_DISABLE_BZIP2=TRUE \ # -D FT_DISABLE_PNG=TRUE \ # -D FT_DISABLE_HARFBUZZ=TRUE \ # -D FT_DISABLE_BROTLI=TRUE [...] # # - NOTE: If a package is set as DISABLED, it cannot be set as REQUIRED # without unsetting the DISABLED value first. For example, if # `FT_DISABLE_HARFBUZZ=TRUE' has been set (Cache is present), you need to # call `FT_DISABLE_HARFBUZZ=FALSE' before calling # `FT_REQUIRE_HARFBUZZ=TRUE'. # # - Installation of FreeType can be controlled with the CMake variables # `SKIP_INSTALL_HEADERS', `SKIP_INSTALL_LIBRARIES', and `SKIP_INSTALL_ALL' # (this is compatible with the same CMake variables in zlib's CMake # support). # To minimize the number of cmake_policy() workarounds, # CMake >= 3 is requested. cmake_minimum_required(VERSION 3.0) if (NOT CMAKE_VERSION VERSION_LESS 3.3) # Allow symbol visibility settings also on static libraries.

We have to help `pkg-config` since it can't recognize that there is no shared library installed. Note that meson already does exactly the same. * builds/unix/configure.raw (REQUIRES_PRIVATE, LIBS_PRIVATE): Rename to... (PKGCONFIG_REQUIRES_PRIVATE, PKGCONFIG_LIBS_PRIVATE): This. Adjust them depending on `$enable_shared`. (PKGCONFIG_REQUIRES, PKGCONFIG_LIBS): New variables. * builds/unix/freetype2.in, builds/unix/unix-def.in: Use new and updated variables. 2022-03-25 Werner Lemberg <wl@gnu.org> Add `FT_FACE_FLAG_SBIX_OVERLAY` and `FT_HAS_SBIX_OVERLAY`. * include/freetype/freetype.h (FT_FACE_FLAG_SBIX_OVERLAY, FT_HAS_SBIX_OVERLAY): New macro. * src/sfnt/ttsbit.c (tt_face_load_sbit): Handle `FT_FACE_FLAG_SBIX_OVERLAY`.

Fixes issue #998. 2022-03-25 Werner Lemberg <wl@gnu.org> Add `FT_FACE_FLAG_SBIX` and `FT_HAS_SBIX`. Fonts with 'sbix' tables need special handling by the application. * include/freetype/freetype.h (FT_FACE_FLAG_SBIX, FT_HAS_SBIX): New macros. * src/sfnt/sfobjs.c (sfnt_load_face): Set `FT_FACE_FLAG_SBIX` if 'sbix' table is present. 2022-03-25 Werner Lemberg <wl@gnu.org> * include/freetype/freetype.h (FT_LOAD_SBITS_ONLY): Tag macro as public. 2022-03-24 Carlo Bramini <carlo.bramix@libero.it> [builds/windows] Fix WCE support. * builds/windows/ftsystem.c [_WIN32_WCE]: Include <malloc.h> needed by _alloca. 2022-03-24 Steve Lhomme <robux4@ycbcr.xyz> [build/windows] Improve UWP support. * builds/windows/ftsystem.c [UWP]: Wrap CreateFile2 into CreateFileA. 2022-03-21 Werner Lemberg <wl@gnu.org> * src/sfnt/ttkern.c (tt_face_get_kerning): Exit early if no table. Fixes #1141. 2022-03-20 Ben Wagner <bungeman@chromium.org> [woff2] Support overlap flag for simple glyphs. In the woff2 spec it has been proposed to allow the OVERLAP_SIMPLE flag to be retained through the woff2 format [0]. [0] https://www.w3.org/TR/WOFF2/#glyf_table_format * src/sfnt/sfwoff2.h (GLYF_OVERLAP_SIMPLE): add glyf flag. * src/sfnt/sfwoff2.c (reconstruct_glyf): parse optionFlags and overlapSimpleBitmap[].

We must ensure that the cast to `FT_Int` doesn't change the sign. Fixes #1139. 2022-03-17 Werner Lemberg <wl@gnu.org> [sfnt] Avoid invalid face index. Fixes #1138. * src/sfnt/sfobjs.c (sfnt_init_face), src/sfnt/sfwoff2.c (woff2_open_font): Check `face_index` before decrementing. 2022-03-07 Werner Lemberg <wl@gnu.org> Documentation, whitespace. 2022-03-05 Anuj Verma <anuj@womp.xyz> [sdf] Fix corner checks and improve performance. * src/sdf/ftsdf.c (sdf_generate_bounding_box): Always check for a corner if two distances (for different curves) are very close. (sdf_conic_to): Check whether the conic curve can be treated as a line (which happens if the control point coincides with any end point). 2022-03-05 Anuj Verma <anuj@womp.xyz> [sdf] Implement deviation-based splitting for Bezier curves. * src/sdf/ftsdf.c (split_sdf_cubic, split_sdf_shape): Add checks to figure out the deviation of Bezier curves and stop splitting if the curve is flat enough. * src/sdf/ftsdfcommon.h (ONE_PIXEL): New macro. 2022-03-05 Anuj Verma <anuj@womp.xyz> * include/freetype/freetype.h: Improve SDF documentation. 2022-03-03 Ben Wagner <bungeman@chromium.org> [sfnt] Fix bounds check in SVG. The `SVG_DOCUMENT_LIST_MINIMUM_SIZE` macro is non trivial and not protected by parentheses. As a result, the expression `table_size - SVG_DOCUMENT_LIST_MINIMUM_SIZE` expands to `table_size - 2U + SVG_DOCUMENT_RECORD_SIZE` instead of the expected `table_size - (2U + SVG_DOCUMENT_RECORD_SIZE)`. This causes an incorrect bounds check which may lead to reading past the end of the `SVG ` table. * src/sfnt/ttsvg.c (tt_face_load_svg): wrap macro definitions in parentheses. Bug: https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=45179 2022-02-23 Ben Wagner <bungeman@chromium.org> [psaux] Full bounds check for OtherSubr 19. It is possible for OtherSubr 19 to be invoked when `decoder->buildchar` is NULL (so that `decoder->len_buildchar` is 0), the `blend` is non-NULL with `blend->num_designs` set to 2, and the user supplied `idx` to be large (for example 0xFFFFFFFE). Since these are all `FT_UInt32` the existing bounds check overflows in a well defined manner, allowing for an invalid call to `memcpy`. In addition, it is possible to call OtherSubr 19 with `decoder->len_buildchar`, `blend->num_designs`, and `idx` all zero (implying that `blend->weight_vector` and `decoder->buildchar` are NULL). This passes the bounds check (it is logically always fine to copy nothing starting at index zero) but may invoke undefined behavior in `ft_memcpy` if it is backed by `memcpy`. Calling `memcpy` with either the `src` or `dst` NULL is undefined behavior (even if `count` is zero). * src/psaux/psintrp.c (cf2_interpT2CharString): Correctly check that `blend->num_designs` can be copied to `decoder->buildchar[idx]`. Also avoid passing NULL to `ft_memcpy`. Bug: https://crbug.com/1299259 2022-02-21 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> [cmake] Drop the support of CMake 2.x. * CMakeLists.txt: Require CMake 3.0 (released on 2014) or newer. The issue #1059 reports the difficulty to support both of CMake 2.x and newer one by single CMakeLists.txt without the inflation of cmake_policy() workarounds. For better maintainability, the support of CMake 2.x is dropped. 2022-02-19 Werner Lemberg <wl@gnu.org> * src/bdf/README: Updated. 2022-02-19 Werner Lemberg <wl@gnu.org> * builds/mac/ftmac.c, src/base/ftmac.c: s|FT_MAC_H|<freetype/ftmac.h>|. 2022-02-19 Werner Lemberg <wl@gnu.org> src/sfnt/ttkern.c (tt_face_load_kern): Micro-optimize. A kerning table can be handled by binary search if it has equal entries. Fixes #1132. 2022-02-17 Steve Lhomme <robux4@ycbcr.xyz> Alexei Podtelezhnikov <apodtele@gmail.com> [builds/windows] Add support for legacy UWP builds. * builds/windows/ftsystem.c: Add neccessary macro substitutions to enable strict UWP builds. See !141. 2022-02-16 Werner Lemberg <wl@gnu.org> ftmm.h: Minor documentation improvement. 2022-02-13 Alexei Podtelezhnikov <apodtele@gmail.com> [pshinter] Tune PSH_STRONG_THRESHOLD_MAXIMUM value. Before the change, the hinting engine frequently confused horizontal stem and serif hints making some stems too thin and some serifs too thick. The value was tuned using serif fonts from the URW+ base 35 collection. * src/pshinter/pshalgo.c [PSH_STRONG_THRESHOLD_MAXIMUM]: s/30/12/. 2022-02-12 Werner Lemberg <wl@gnu.org> t1tables.h: Documentation improvements. 2022-02-12 Werner Lemberg <wl@gnu.org> t1tables.h: Whitespace. 2022-02-11 Werner Lemberg <wl@gnu.org> [type42] Fix `FT_Get_PS_Font_Private` for this format. Since Type42 fonts don't have a 'Private' dictionary, the return value should be `FT_Err_Invalid_Argument`. * src/type42/t42drivr.c (t42_ps_get_font_private): Removed. (t42_service_ps_info): Updated. 2022-02-09 Alexei Podtelezhnikov <apodtele@gmail.com> [pshinter] Clear reused mask. In PS hinter, memory allocations persist until the module is done. Therefore, we have to clear reused masks. * src/pshinter/pshrec.c (ps_mask_table_alloc): Clear reused mask. 2022-02-09 Alexei Podtelezhnikov <apodtele@gmail.com> [pshinter] Use unsigned indices. This reduces casting and eliminates some checks. * src/pshinter/pshrec.c (ps_mask_test_bit, ps_mask_table_merge, ps_dimension_add_t1stem, ps_hints_t1stem3): Updated. (ps_dimension_add_counter): Updated, unnecessary checks removed. 2022-02-08 Alexei Podtelezhnikov <apodtele@gmail.com> [pshinter] Fix mask merging. We forgot to update the number of bits when merging a larger mask into a smaller one. This fix might have rendering effects. * src/pshinter/pshrec.c (ps_mask_table_merge): Inherit the number of bits from a larger mask. There is no need to zero unused bits, already zeroed during allocation. (ps_mask_clear_bit): Removed. (ps_mask_ensure): Minor. 2022-02-08 Alexei Podtelezhnikov <apodtele@gmail.com> [pshinter] Revise the hint table handling. * src/pshinter/pshrec.c (ps_hint_table_ensure): Remove redundant size check; avoid array zeroing because it is fully initialized when used. (ps_hint_table_alloc): Fix off-by-one comparison and remove another zeroing of the array elements. 2022-02-06 Werner Lemberg <wl@gnu.org> Various minor doc fixes. 2022-02-06 Alexei Podtelezhnikov <apodtele@gmail.com> [builds/windows] Add SVG to to project files. * builds/windows/vc2010/freetype.vcxproj: Updated. * builds/windows/vc2010/freetype.vcxproj.filters: Updated. * builds/windows/visualc/freetype.vcproj: Updated. 2022-02-03 Alexei Podtelezhnikov <apodtele@gmail.com> * src/winfonts/winfnt.c (fnt_face_get_dll_font): Trace font resources. 2022-02-02 Eric Jing <@CPUcontrol> [cmake] Fix build on MacOS. * CMakeLists.txt (CMAKE_OSX_ARCHITECTURES): Update value to fix the building of a framework on MacOS. * builds/mac/freetype-Info.plist (CFBundleExecutable): Make identifier lowercase only. Fixes #1127. 2022-02-02 Alexei Podtelezhnikov <apodtele@gmail.com> [psaux] Revise `PS_Table` handling. The old impleemntation was not using `FT_REALLOC`, buing too careful with the offset rebasing. It shoudl be safe to rely on the base movements. * src/psaux/psobjs.c (reallocate_t1_table, shift_elements): Combine into... (ps_table_realloc): ... this function based on `FT_REALLOC`. (ps_table_done): Simplified.

This reverts commit d276bcb7f0c02c20d3585b2e5626702df6d140a6. The original commit did avoid the use of uninitialized memory. However, it appears that the original commit is no longer required. The underlying issue was resolved by a change in freetype2-testing "Build bzip2 correctly." [0]. Prior to [0] bzip2 was built without msan, so bzip2 writes were not tracked or considered initialized. Clearing `buffer` in the original commit allowed msan to see the `buffer` content initialized once in FreeType code, but msan saw no writes into buffer from bzip2. With bzip2 now built with msan, the bzip2 writes are properly instrumented and msan sees the bzip2 writes into the buffer. As a result the original commit can be safely reverted to allow for better detection of other uninitialized data scenarios. * src/bzip2/ftbzip2.c (FT_Stream_OpenBzip2): Revert to using `FT_QNEW`. [0] https://github.com/freetype/freetype2-testing/commit/3c052a837a3c960709227a0d6ddd256e87b88853 2022-01-11 Ben Wagner <bungeman@chromium.org> [type42] Track how much type42 ttf data is available. Currently `T42_Open_Face` eagerly allocates 12 bytes for the ttf header data which it expects `t42_parse_sfnts` to fill out from /sfnts data. However, there is no guarantee that `t42_parse_sfnts` will actually be called while parsing the type42 data as the /sfnts array may be missing or very short. This is also confusing behavior as it means `T42_Open_Face` is tightly coupled to the implementation of the very distant `t42_parse_sfnts` code which requires at least 12 bytes to already be reserved in `face->ttf_data`. `t42_parse_sfnts` itself eagerly updates `face->ttf_size` to track how much space is reserved for ttf data instead of traking how much data has actually been written into `face->ttf_data`. It will also act strangely in the presense of multiple /sfnts arrays. * src/type42/t42objs.c (T42_Open_Face): ensure `ttf_data` is initialized to NULL. Free `ttf_data` on error. * src/type42/t42parse.c (t42_parse_sfnts): delay setting `ttf_size` and set it to the actual number of bytes read.

The existing code did not reset `localpoints` to `NULL` when there were no private point numbers. If the previous tuple did have private point numbers and set `localpoints` to `ALL_POINTS` this would not be cleared and the wrong branch would be taken later, leading to possible heap buffer overflow. * src/truetype/ttgxvar.c (tt_face_vary_cvt): Reset `localpoints` to `NULL` when it isn't valid. Fixes: https://crbug.com/1284742 2022-01-02 Werner Lemberg <wl@gnu.org> * builds/unix/configure.raw: Restore `SYSTEM_ZLIB` variable. This was accidentally removed with commit 93ebcbd0 almost eight years ago. 2021-12-27 Alexander Borsuk <me@alex.bio> Fix warnings for CMake Unity builds. * src/cache/ftcbasic.c (FT_COMPONENT): Undefine macro before redefinition. * src/smooth/ftgrays.c (TRUNC, FRACT): Ditto. 2021-12-18 Alexander Borsuk <alexander.borsuk@qnective.com> Clang-Tidy warning fixes. * src/base/ftobjs.c (FT_Get_Paint): Operator has equivalent nested operands. * src/bdf/bdflib.c (_bdf_add_property): Value stored to `fp` is never read. * src/sdf/ftbsdf.c (bsdf_init_distance_map): Value stored to `pixel` is never read. * src/sdf/ftsdf.c (split_sdf_shape): Value stored to `error` is never read. 2021-12-17 Eli Schwartz <eschwartz@archlinux.org> * meson.build: Optimize lookup for `python3` program. The python module's `find_installation` method is intended to provide routines for compiling and installing python modules into the `site-packages` directory. It does a couple of slow things, including run an introspection command to scrape sysconfig info from the detected interpreter, which are not needed for the sole use case of invoking the found installation as an executable. Furthermore, when invoked without the name or path of a python binary, it is hardcoded to always look for `python3` corresponding to the interpreter meson itself uses to run. So using `find_installation` did not even allow detecting `python2` as a fallback. Instead, switch to a simple `find_program` lookup that finishes as soon as the program is found. 2021-12-17 Eli Schwartz <eschwartz@archlinux.org> * builds/meson/*.py: Fix name of python executable for auxiliary scripts. The previous change to check the return code of `run_command` invocations caused the CI to fail. Although most scripts used `python_exe` as the program command, the script to determine the project version did not. But, all scripts used `python` as the shebang, and this is not available on all systems. Particularly Debian does not provide a `python` command, though `python3` does exist. This meant that formerly the version number was lacking, and now the build simply fails. Instead, rely on `python3` since it is guaranteed to exist when running meson, and `python2` is end of life anyway. 2021-12-17 Eli Schwartz <eschwartz@archlinux.org> * meson.build: Check the return value of `run_command`. By default, errors are not checked and a command that is somehow broken will just capture incorrect output (likely an empty string). Current development versions of meson now raise a warning for this implicit behavior, and advise explicitly setting the `check:` keyword argumend to determine whether a failing return code should be considered an error. Since none of the commands in this project are expected to fail, mark them as required to succeed. 2021-12-13 Alexei Podtelezhnikov <apodtele@gmail.com> [truetype] Upstream the hdmx binary search. * src/truetype/ttobjs.h (TT_SizeRec): Add `widthp` for the hdmx widths. * src/truetype/ttobjs.c (tt_size_reset): Initialize `widthp` even though it might never be used by the interpreter. * src/truetype/ttgload.c (tt_loader_init): Avoid repeated searches in the hdmx table. 2021-12-12 Alexei Podtelezhnikov <apodtele@gmail.com> [truetype] Reset the IUP-called flags for each subglyph.

The `hdmx` table is supposed to be sorted by ppem size, which enables binary search. We also drop the check for the sufficient length of the record because it is now enforced when the table is loaded. * include/freetype/internal/tttypes.h (TT_FaceRec): Store the `hdmx` record pointers sorted by ppem instead of ppem's themselves. * src/truetype/ttpload.c (tt_face_load_hdmx): Prudently sort records. (tt_face_get_device_metrics): Implement binary search to retrieve advances. 2021-12-12 Alexei Podtelezhnikov <apodtele@gmail.com> [truetype] Honor FT_LOAD_ADVANCE_ONLY if `hdmx` is usable. This simply shortcuts the glyph loading if FT_LOAD_ADVANCE_ONLY is specified by FT_Get_Advances and the `hdmx` data are located. Particularly, the classic v35 interpreter or "verified" ClearType fonts might see 100x speed up in retrieving the hdmx cache. * src/truetype/ttgload.c (TT_Load_Glyph): Insert the shortcut. 2021-12-12 Alexei Podtelezhnikov <apodtele@gmail.com> [truetype] Initialize the loader with `hdmx` data. The `hdmx` matching can be done before the glyph is loaded. * include/freetype/internal/tttypes.h (TT_LoaderRec): Add a field. * src/truetype/ttgload.c (compute_glyph_metrics): Relocate the `hdmx` code from here... (tt_loader_init): ... to here, before the glyph is loaded. 2021-12-12 Alexei Podtelezhnikov <apodtele@gmail.com> [truetype] Relocate subpixel flag setting. `TT_RunIns` is too busy to deal with subpixel flags. It is better to set them in `tt_loader_init`, which is executed before each glyph program. * src/truetype/ttinterp.c (TT_RunIns): Move the flag setting from here... * src/truetype/ttgload.c (tt_loader_init): ... to here. 2021-12-12 Alexei Podtelezhnikov <apodtele@gmail.com> [truetype] Limit INSTCTRL appication within specs. * src/truetype/ttinterp.c (Ins_INSTCTRL): Limit its global effects to the CVT program and local effects to the glyph program. This also fixes an Infinality buglet. The `ignore_x_mode` should be locally unset by the glyph program. 2021-12-09 Ben Wagner <bungeman@chromium.org> [bdf] Fix use of uninitialized value. In _bdf_readstream if the data contained no newline then the buffer would continue to grow and uninitialized data read until either the uninitialized data contained a newline or the buffer reached its maxiumum size. The assumption was that the line was always too long and the buffer had been filled, however this case can also happen when there is not enough data to fill the buffer. Correct this by properly setting the cursor to the end of the available data, which may be different from the end of the buffer. This may still result in one extra allocation, but only on malformed fonts. * src/bdf/bdflib.c (_bfd_readstream): Correctly update cursor. Remove unread set of `avail`. Bug: https://lists.nongnu.org/archive/html/freetype-devel/2021-12/msg00001.html 2021-12-07 Alexei Podtelezhnikov <apodtele@gmail.com> [truetype] Reduce Infinality footprint again. * src/truetype/ttgload.c (compute_glyph_metrics): Streamline and prioritize the Infinality checks to use `hdmx`. 2021-12-07 Cameron Cawley <ccawley2011@gmail.com> [builds/windows] Guard some non-ancient API.

However `g++ -Wold-style-cast` warns for macros with C-style casts even for system header files; this also affects directories included with `-isystem`.

Previously the `blend->weight_vector`, `blend->default_weight_vector`, and `blend->design_pos` were set early to allocated but uninitialized memory under the assumption that the memory would eventually be initialized. However, it is possible that some of the required keywords may not actually be present, leaving the memory uninitialized. This is different from a present but invalid table, which would produce an error. Reported as https://bugs.chromium.org/p/chromium/issues/detail?id=1261762 * src/type1/t1load.c (t1_allocate_blend): Remove early allocation and initialization. (parse_blend_design_positions, parse_weight_vector): Parse into local and assign to blend if valid. (T1_Open_Face): Check that if a blend exists that it has the weight vector and design positions. 2021-10-21 Ben Wagner <bungeman@chromium.org> [cff] Commit vstore data and regions on allocation. The vstore->regionCount and vstore->dataCount were read directly from the data. However, vstore->varRegionList and vstore->varData would still contain uninitialized entries with uninitialized pointers in the event of an error, leading to issues when attempting to clean up. Reportd as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=40104 * src/cff/cffload.c (cff_vstore_load): Read the region and data counts into locals and update the vstore counts immediately after each entry becomes free-able. 2021-10-20 Ben Wagner <bungeman@chromium.org> [sfnt] Delay setting gasp ranges and count until computed. Previously, the gasp.numRanges was set and gasp.gaspRanges was allocated and assigned before a possible early exit if the frame could not be entered. It is also possible that the gaspRanges allocation could fail but the numRanges still be set to non-zero. In such cases an error would be returned, but the face would have a gasp in an inconsistent state which may still be accessed. Reported as https://bugs.chromium.org/p/chromium/issues/detail?id=1261450 * src/sfnt/ttload.c (tt_face_load_gasp): Delay setting gasp.numRanges and gasp.gaspRanges until after the ranges are initialized. 2021-10-20 Ben Wagner <bungeman@chromium.org> [sfnt] Delay setting names and langTags until computed. Previously, the table->names and table->langTags fields were created pointing to uninitialized memory and an early exit could happen if the frame could not be entered. The caller would then be unable to properly dispose of the memory as the string fields had not been initialized. Reported as https://bugs.chromium.org/p/chromium/issues/detail?id=1261343 * src/sfnt/ttload.c (tt_face_load_name): delay setting table->langTags and table->names until after the memory they will point to is fully initialized. 2021-10-20 Alexei Podtelezhnikov <apodtele@gmail.com> * tests/issue-1063/main.c: s/PATH_MAX/FILENAME_MAX/.

These two are not equal when FreeType is used as a subproject, such as in `freetype-demos`. In that case, `source_root` points at the root project, causing the docs build to fail. 2021-10-05 Alexei Podtelezhnikov <apodtele@gmail.com> * src/smooth/ftgrays.c (FT_DIV_MOD): Limit the ARM workaround. 2021-10-05 Alexei Podtelezhnikov <apodtele@gmail.com> [builds/unix, builds/vms] Standardize `mmap` failure. * builds/unix/ftsystem.c (FT_Stream_Open): Check for MAP_FAILED. * builds/vms/ftsystem.c (FT_Stream_Open): Ditto. This should cover https://savannah.nongnu.org/patch/?5909 as well. 2021-10-05 Hugh McMaster <hugh.mcmaster@outlook.com> autogen.sh: Only copy submodules if building from a git branch. `autogen.sh` fails if building from a standard source tarball. Firstly, git expects to be called in a git repository, then `copy_submodule_files` blindly attempts to copy files. Debian, Ubuntu, Linux Mint, and other derivatives all run `autogen.sh` before compiling to regenerate build files. This patch ensures that various git commands are only called and 'dlg' files are only copied if `autogen.sh` is called from a git repository. 2021-10-05 Alexei Podtelezhnikov <apodtele@gmail.com> * include/freetype/internal/ftgloadr.h: Add missing header.

After this commit, autoconf builds will fully rely on <limits.h> rather than falling back on it if AC_CHECK_SIZEOF failed for some reason. There is a risk that misconfigured cross-compilation might have wrong headers. Note that Meson and CMake builds always relied on <limits.h> for sizes and availability of integer types. 2021-09-25 Alexei Podtelezhnikov <apodtele@gmail.com> Propagate sign when reading OFF3. Signed 24-bit values are extremely rare. FreeType only reads them in PFR fonts with bitmap strikes conditionally. They have not been seen in the known fonts. That is why this bug could never be discovered. `FT_FRAME_OFF3` propagates sign correctly. * include/freetype/internal/ftstream.h (FT_PEEK_OFF3, FT_PEEK_OFF3_LE): Propagate sign into 32-bit value. (FT_GET_OFF3, FT_READ_OFF3): Needed fixing but removed as unused. 2021-09-25 Alexei Podtelezhnikov <apodtele@gmail.com> [bdf] Simplify comment collection or lack thereof. BDF comments are neither actually collected nor retrieved. There is no need to be fancy with delimiters. * src/bdf/bdflib.c (_add_bdf_comment): Delimit comments with zeros...

With Windows memory management tracking heap, it is important to use it during the stream opening fallback. In Unix, the argument is unused, but it is better to set it correctly. * src/base/ftobjs.c (FT_Stream_New): Set memory before calling `FT_Stream_Open`. * builds/windows/ftsystem.c, builds/unix/ftsystem.c (FT_Stream_Open, ft_close_stream_by_free): Call `ft_alloc` and `ft_free` with proper memory argumment. 2021-09-22 Alexei Podtelezhnikov <apodtele@gmail.com> [builds/windows] Revert back to `CreateFileA` only.

The loss of precision is tolerable until the divisors (the components dx and dy) approach 32 - PIXEL_BITS. With PIXEL_BITS = 8, this corresponds to 65,000 pixels or the bitmap size that we refuse to render anyway.

Such long tricky family names are removed from the `trick_names'. 2021-08-24 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> [truetype] Add 2 tricky font names. Additional fix for the issue #1087. * src/truetype/ttobjs.c (tt_check_trickyness_family): Add 2 tricky font names reported in #1087. 2021-08-24 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> [truetype] New function to skip the randomization tag. * src/truetype/ttobjs.c (tt_skip_pdffont_random_tag): New function to skip the randomization tag in the names of the fonts embedded in a PDF. It is used by tt_check_trickyness_family(), to keep from mistaking "DLC" in the randomization tag as a tricky font name. See discussion in: https://lists.nongnu.org/archive/html/freetype-devel/2021-02/msg00002.html For technical detail about the randomization tag, please find PDF Reference 5.5.3 "Font Subsets".

Put the null cell at the end of the pool and store it explicitly so that we can use it as both the limit and the dumpster. * src/smooth/ftgrays.c (gray_TWorker): Store the last `cell_null` and remove unnecesary fields. (NULL_CELL_PTR, CELL_IS_NULL): Remove in favor of explicit `cell_null`. (gray_dump_cells, gray_set_cell, gray_sweep{,_direct}): Update callers. (gray_convert_glyph_inner): Trace remaining cells (oh well). (gray_convert_glyph): Set up `cell_null` and slightly improve the pool management. 2021-08-20 Alexei Podtelezhnikov <apodtele@gmail.com> [base] Restore quiet no-op rendering of bitmap glyphs.

Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=36243 * src/smooth/ftgrays.c(ADD_LONG, SUB_LONG, MUL_LONG, NEG_LONG) [STANDALONE_]: Removed, unused. (ADD_INT) [STANDALONE_]: New macro. (FT_INTEGRATE): Use ADD_INT. 2021-08-07 Dominik Röttsches <drott@chromium.org> [sfnt] Add API for retrieving a 'COLR' v1 'ClipBox' table. The optional 'COLR' v1 glyph-specific clip box helps upstream graphics libraries allocate a sufficiently large bitmap for a glyph without having to traverse the glyph graph for that. See https://github.com/googlefonts/colr-gradients-spec/issues/251 for background on the introduction of this specification change. * include/freetype/ftcolor.h (FT_ClipBox): New structure. (FT_Get_Color_Glyph_ClipBox): New function declaration. * include/freetype/internal/sfnt.h (TT_Get_Color_Glyph_ClipBox_Func): New function type. (SFNT_Interface, FT_DEFINE_SFNT_INTERFACE): Use it. * src/base/ftobjs.c (FT_Get_Color_Glyph_ClipBox): New function to link API with SFNT implementation. * src/sfnt/sfdriver.c (sfnt_interface): Updated. * src/sfnt/ttcolr.c (Colr): New field `clip_list`. (tt_face_load_colr): Parse global clip list offset. (tt_face_get_color_glyph_clipbox): New function to find the clip box for a glyph id from the clip list array. * src/sfnt/ttcolr.h: Updated. 2021-08-06 Werner Lemberg <wl@gnu.org> [smooth] Fix left shifts of negative numbers. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=36241 * src/smooth/ftgrays.c (LEFT_SHIFT): New macro. (gray_render_conic) [BEZIER_USE_DDA]: Use it. 2021-08-02 Werner Lemberg <wl@gnu.org> * meson.build: Fix zlib support. This commit synchronizes zlib support with both autotools and cmake: If no external zlib is found (or intentionally disabled on the command line), use the internal zlib by undefining `FT_CONFIG_OPTION_SYSTEM_ZLIB` without modifying `FT_CONFIG_OPTION_USE_ZLIB`. Also improve summary output. Problem reported by Moazin. 2021-08-02 Anuj Verma <anujv@iitbhilai.ac.in> [sdf] Fix out-of-range-access. * src/sdf/ftbsdf.c (first_pass, second_pass): Fix range during forward pass. Otherwise the index goes out of range for the last column. Fixes issue #1077. 2021-08-02 Anuj Verma <anujv@iitbhilai.ac.in> Fix invalid memory access in `bsdf` rasterizer. Do not generate SDF from bitmap if the `FT_GLYPH_OWN_BITMAP` flag is not set. In some cases the bitmap buffer is freed but still points to a valid address; to handle those cases check the flag before accessing the memory. * src/sdf/ftsdfrend.c (ft_bsdf_render): Handle the above case. Also, return an error message if the bitmap's rows/pitch is invalid, otherwise `slot->buffer` might be assigned to some invalid memory location. (ft_sdf_render): Same as above. Plus, move the outline back to original state after rasterization and not if any error occurs. 2021-07-29 Heiko Becker <heirecka@exherbo.org> * meson.build: Honor `--includedir` instead of hard-coding 'include'. 2021-07-29 Werner Lemberg <wl@gnu.org> src/sfnt/ttcolr.c: Minor formatting. 2021-07-29 Dominik Röttsches <drott@chromium.org> [sfnt] 'COLR' v1 PaintSweepGradient spec update * src/sfnt/ttcolr.c (read_paint): PaintSweepGradient follows other spec changes and now has the angles specified as F2DOT14, reflect that in the implementation. * include/freetype/ftcolor.h (FT_PaintSweepGradient): Update documentation. 2021-07-29 Dominik Röttsches <drott@chromium.org> [sfnt] Retrieve affine matrix from offset in 'COLR' v1 parsing. * src/sfnt/ttcolr.c (read_paint): Implement spec change where affine transform matrix is now referenced by offset instead of being placed inline in the PaintTransform table. 2021-07-29 Dominik Röttsches <drott@chromium.org> [sfnt] 'COLR' v1 PaintSkew related spec updates * src/sfnt/ttcolr.c (read_paint): Implement spec changes around PaintSkew, PaintSkewAroundCenter. Update parsing to read shorter values as changed in the spec. * include/freetype/ftcolor.h (FT_PaintSkew): Update documentation. 2021-07-29 Dominik Röttsches <drott@chromium.org> [sfnt] PaintRotate/PaintRotateAroundCenter spec updates * src/sfnt/ttcolr.c (read_paint): Implement spec change where PaintRotate and PaintRotateAroundCenter were split for a more compact format definition. Update parsing to read shorter values as changed in the spec. * include/freetype/ftcolor.h (FT_PaintRotate): Update documentation. 2021-07-29 Dominik Röttsches <drott@chromium.org> [sfnt] 'COLR' v1 PaintTranslate and PaintScale precision * src/sfnt/ttcolr.c (read_paint): Implement spec changes in PaintTranslate and PaintScale and friends. Update parsing to read new shorter values. 2021-07-29 AnuthaDev <anuthadev@gmail.com> README.git: Add Code of Conduct. 2021-07-25 Werner Lemberg <wl@gnu.org> ChangeLog housekeeping. Archive old `ChangeLog` file. We no longer write ChangeLog entries manually; instead, the file will be created from commit messages (which should be formatted in GNU's ChangeLog style) by a call to gitlog-to-changelog --format='%B%n' or something similar (this script is part of the 'gnulib' repository). 2021-07-24 Werner Lemberg <wl@gnu.org> Fix some `cppcheck` warnings. * src/bzip2/ftbzip2.c (ft_bzip2_file_skip_output), src/gzip/ftgzip.c (ft_gzip_file_skip_output): Reduce scope of `delta`. * src/psaux/psintrp.c, src/psaux/psintrp.h (cf2_interpT2CharString): Add `const` to `buf` parameter. * src/raster/ftraster.c (DelOld): Add `const` to `profile` parameter. (Vertical_Sweep_Span): Reduce scope of `target`. (FT_Outline_Get_CBox): Reduce scope of `xMin`, `xMax`, `yMin`, `yMax`. * src/smooth/ftgrays.c (gray_render_conic): Reduce scope of `split`. (gray_sweep, gray_sweep_direct): Reduce scope of `area`. * src/tools/apinames.c (names_dump) <OUTPUT_WATCOM_LBC>: Reduce scope of `temp`. 2021-07-24 AnuthaDev <anuthadev@gmail.com> * .gitlab-ci.yml: Fixed cmake build, using correct options. 2021-07-24 AnuthaDev <anuthadev@gmail.com> * CMakeLists.txt: Make `cmake` handle disabled dependencies correctly. Include 'CMakeDependentOption'. Replace `FT_WITH_XXX` options with `FT_DISABLE_XXX` and `FT_REQUIRE_XXX` pairs. Update option logic accordingly. Fixes #1066. 2021-07-24 Ben Wagner <bungeman@chromium.org> [autofit] Split `afwrtsys.h`. The header file `afwrtsys.h` has two distinct functions: to include the required writing system headers and also to generate code for each writing system. At each current use site only one or the other is used, with various macro trickery selecting one or the other. Split this header into `afws-decl.h` for the required writing system declarations and `afws-iter.h` for iterating over the writing systems to generate code. The motivation for this change is that the Visual C++ compiler treats the standard include guard idiom like `#pragma once` 'if no non-comment code or preprocessor directive comes before or after the standard form of the idiom'. It appears to check this after macro expansion, so if `WRITING_SYSTEM` expands to empty the bottom of `afwrtsys.h` is empty and looks like the standard include guard idiom which is treated like `#pragma once`, so subsequent inclusion of `afwrtsys.h` is elided. Fixes #1075. * src/autofit/afglobal.c (af_writing_system_classes), src/autofit/aftypes.h (AF_WritingSystem), src/autofit/rules.mk (AUTOF_DRV_H): Updated. * src/autofit/afwrtsys.h: Split into... * src/autofit/afws-decl.h, src/autofit/afws-iter.h: New files.

FreeType 2.12.0 =============== Homepage: https://www.freetype.org FreeType is a freely available software library to render fonts. It is written in C, designed to be small, efficient, highly customizable, and portable while capable of producing high-quality output (glyph images) of most vector and bitmap font formats. Please read the `docs/CHANGES` file, it contains IMPORTANT INFORMATION. Read the files `docs/INSTALL*` for installation instructions; see the file `docs/LICENSE.TXT` for the available licenses. For using FreeType's git repository instead of a distribution bundle, please read file `README.git`. The FreeType 2 API reference is located in directory `docs/reference`; use the file `index.html` as the top entry point. [Please note that currently the search function for locally installed documentation doesn't work due to cross-site scripting issues.] Additional documentation is available as a separate package from our sites. Go to https://download.savannah.gnu.org/releases/freetype/ and download one of the following files. freetype-doc-2.12.0.tar.xz freetype-doc-2.12.0.tar.gz ftdoc2120.zip To view the documentation online, go to https://www.freetype.org/freetype2/docs/ Mailing Lists ------------- The preferred way of communication with the FreeType team is using e-mail lists. general use and discussion: freetype@nongnu.org engine internals, porting, etc.: freetype-devel@nongnu.org announcements: freetype-announce@nongnu.org git repository tracker: freetype-commit@nongnu.org The lists are moderated; see https://www.freetype.org/contact.html how to subscribe. Bugs ---- Please submit bug reports at https://gitlab.freedesktop.org/freetype/freetype/-/issues Alternatively, you might report bugs by e-mail to `freetype-devel@nongnu.org`. Don't forget to send a detailed explanation of the problem -- there is nothing worse than receiving a terse message that only says 'it doesn't work'. Patches ------- For larger changes please provide merge requests at https://gitlab.freedesktop.org/freetype/freetype/-/merge_requests Alternatively, you can send patches to the `freetype-devel@nongnu.org` mailing list -- and thank you in advance for your work on improving FreeType! Details on the process can be found here: https://www.freetype.org/developer.html#patches Enjoy!

README.git ========== repository issues ----------------- FreeType's official repository site is https://gitlab.freedesktop.org/freetype , from which the 'freetype.git' and 'freetype-demos.git' repositories can be cloned in the usual way. git clone https://gitlab.freedesktop.org/freetype/freetype.git git clone https://gitlab.freedesktop.org/freetype/freetype-demos.git If you want to use the Savannah mirror instead, you have to do a slightly different incantation because the repository names contain digit '2' for historical reasons. git clone \ https://git.savannah.nongnu.org/git/freetype/freetype2.git \ freetype git clone \ https://git.savannah.nongnu.org/git/freetype/freetype2-demos.git \ freetype-demos standard builds with `configure` -------------------------------- The git repository doesn't contain pre-built configuration scripts for UNIXish platforms. To generate them say sh autogen.sh which in turn depends on the following packages: automake (1.10.1) libtool (2.2.4) autoconf (2.62) The versions given in parentheses are known to work. Newer versions should work too, of course. Note that `autogen.sh` also sets up proper file permissions for the `configure` and auxiliary scripts. The `autogen.sh` script checks whether the versions of the above three tools match the numbers above. Otherwise it will complain and suggest either upgrading or using environment variables to point to more recent versions of the required tools. Note that `aclocal` is provided by the 'automake' package on Linux, and that `libtoolize` is called `glibtoolize` on Darwin (OS X). alternative build methods ------------------------- For static builds that don't use platform-specific optimizations, no configure script is necessary at all; saying make setup ansi make should work on all platforms that have GNU `make` (or `makepp`). A build with `cmake` or `meson` can be done directly from the git repository. However, if you want to use the `FT_DEBUG_LOGGING` macro (see file `docs/DEBUG` for more information) it is currently mandatory to execute `autogen.sh` in advance; this script clones the 'dlg' git submodule and copies some files into FreeType's source tree.

CHANGES BETWEEN 2.11.1 and 2.12.0 I. IMPORTANT CHANGES - FreeType now handles OT-SVG fonts, to be controlled with `FT_CONFIG_OPTION_SVG` configuration macro. By default, it can only load the 'SVG ' table of an OpenType font. However, by using the `svg-hooks` property of the new 'ot-svg' module it is possible to register an external SVG rendering engine. The FreeType demo programs have been set up to use 'librsvg' as the rendering library. This work was Moazin Khatti's GSoC 2019 project. II. MISCELLANEOUS - The handling of fonts with an 'sbix' table has been improved. - Corrected bitmap offsets. - A new tag `FT_PARAM_TAG_IGNORE_SBIX` for `FT_Open_Face` makes FreeType ignore an 'sbix' table in a font, allowing applications to access the font's outline glyphs. - `FT_FACE_FLAG_SBIX` and `FT_FACE_FLAG_SBIX_OVERLAY` together with their corresponding preprocessor macros `FT_HAS_SBIX` and `FT_HAS_SBIX_OVERLAY` enable applications to treat 'sbix' tables as described in the OpenType specification. - The internal 'zlib' code has been updated to be in sync with the current 'zlib' version (1.2.11). - The previously internal load flag `FT_LOAD_SBITS_ONLY` is now public. - Some minor improvements of the building systems, in particular handling of the 'zlib' library (internal vs. external). - Support for non-desktop Universal Windows Platform. - Various other minor bug and documentation fixes. - The `ftdump` demo program shows more information for Type1 fonts if option `-n` is given. - `ftgrid` can now display embedded bitmap strikes. ====================================================================== CHANGES BETWEEN 2.11.0 and 2.11.1 I. IMPORTANT CHANGES - Some fields in the `CID_FaceDictRec`, `CID_FaceInfoRec`, and `FT_Data` structures have been changed from signed to unsigned type, which better reflects the actual usage. It is also an additional means to protect against malformed input. II. MISCELLANEOUS - Cmake support has been further improved. To do that various backward-incompatible changes were necessary; please see file `CMakeLists.txt` for more details. - Since version 2.11.0, a C99 compiler is necessary to compile FreeType. - The experimental 'COLR' v1 API has been updated to the latest OpenType standard 1.9. - The `apinames` tool got a new option `-wV` to output an OpenVMS Linker Option File. - VMS support was updated. - MS Visual Studio support was added to build the demo programs. ====================================================================== CHANGES BETWEEN 2.10.4 and 2.11.0 I. IMPORTANT CHANGES - A new rendering module has been added to create 8-bit Signed Distance Field (SDF) bitmaps for both outline and bitmap glyphs. The new rendering mode is called `FT_RENDER_MODE_SDF`, the pixel mode is `FT_PIXEL_MODE_GRAY8`, and the corresponding raster flag is `FT_RASTER_FLAG_SDF`. This work was Anuj Verma's GSoC 2020 project. - A new, experimental API is now available for surfacing properties of 'COLR' v1 color fonts (as the name says, this is an extension to the 'COLR' table for outline color fonts using the SFNT container format). 'COLR' v1 fonts are a recently proposed addition to OFF and OpenType; specification work currently happens in https://github.com/googlefonts/colr-gradients-spec/ 'COLR' v1 is expected to be merged to OpenType; the ISO standardisation process for adding 'COLR' v1 as an amendment to OFF is underway. Functions similar to the already existing 'COLR' API have been added to access the corresponding data. FT_Get_Color_Glyph_Paint Retrieve the root paint for a given glyph ID. FT_Get_Paint_Layers Access the layers of a `PaintColrLayers` table. FT_Get_Colorline_Stops Retrieve the 'color stops' on a color line. As an input, a color stop iterator gets used, which in turn is retrieved from a paint. FT_Get_Paint Dereference an `FT_OpaquePaint` object and retrieve the corresponding `FT_COLR_Paint` object, which contains details on how to draw the respective 'COLR' v1 `Paint` table. II. MISCELLANEOUS - FreeType has moved its infrastructure to https://gitlab.freedesktop.org/freetype A side effect is that the git repositories are now called `freetype.git` and `freetype-demos.git`, which by default expand to the directories `freetype` and `freetype-demos`, respectively. The documentation has been updated accordingly. FreeType's Savannah repositories will stay; they are now mirrors of the 'freedesktop.org' repositories. - A new function `FT_Get_Transform` returns the values set by `FT_Set_Transform`. - A new configuration macro `FT_DEBUG_LOGGING` is available. It provides extended debugging capabilities for FreeType, for example showing a time stamp or displaying the component a tracing message comes from. See file `docs/DEBUG` for more information. This work was Priyesh Kumar's GSoC 2020 project. - The legacy Type 1 and CFF engines are further demoted due to lack of CFF2 charstring support. You now need to use `FT_Property_Set` to enable them besides the `T1_CONFIG_OPTION_OLD_ENGINE` and `CFF_CONFIG_OPTION_OLD_ENGINE` options, respectively. - The experimental 'warp' mode (AF_CONFIG_OPTION_USE_WARPER) for the auto-hinter has been removed. - The smooth rasterizer performance has been improved by >10%. Note that due to necessary code changes there might be very subtle differences in rendering. They are not visible by the eye, however. - PCF bitmap fonts compressed with LZW (these are usually files with the extension `.pcf.Z`) are now handled correctly. - Improved Meson build files, including support to build the FreeType demo programs. - A new demo program `ftsdf` is available to display Signed Distance Fields of glyphs. - The `ftlint` demo program has been extended to do more testing of its input. In particular, it can display horizontal and vertical acutances for quality assessment, together with computing MD5 checksums of rendered glyphs. [The acutance measures how sharply the pixel coverage changes at glyph edges. For monochrome bitmaps, it is always 2.0 in either X or Y direction. For anti-aliased bitmaps, it depends on the hinting and the shape of a glyph and might approach or even reach value 2.0 for glyphs like 'I', 'L', '+', '-', or '=', while it might be lower for glyphs like 'O', 'S', or 'W'.] - The `ttdebug` demo program didn't show changed point coordinates (bug introduced in version 2.10.3). - It is now possible to adjust the axis increment for variable fonts in the `ftmulti` demo program. - It is now possible to change the hinting engine in the `ftstring` demo program. - The graphical demo programs work better now in native color depth on win32 and x11. ====================================================================== CHANGES BETWEEN 2.10.3 and 2.10.4 (2020-Oct-20) I. IMPORTANT BUG FIXES - A heap buffer overflow has been found in the handling of embedded PNG bitmaps, introduced in FreeType version 2.6. https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2020-15999 If you use option FT_CONFIG_OPTION_USE_PNG you should upgrade immediately. ====================================================================== CHANGES BETWEEN 2.10.2 and 2.10.3 (2020-Oct-10) I. IMPORTANT CHANGES - New flag `FT_OUTLINE_OVERLAP'. If set, make the smooth rasterizer do 4x4 oversampling to mitigate artifacts in pixels partially covered by overlapping contours. Note that this at least quadruples the rendering time. If a glyph in a TrueType font has the `OVERLAP_SIMPLE' or `OVERLAP_COMPOUND' bit set, FreeType automatically selects this rendering mode. II. MISCELLANEOUS - Using the arcane method of including FreeType header files with macros like `FT_FREETYPE_H' is no longer mandatory (but retained as an optional feature for backward compatibility). - Support for building the library with Meson. Building the demo programs with Meson will follow in a forthcoming release. - Minor improvements to the B/W rasterizer. - Auto-hinter support for Medefaidrin script. - Fix various memory leaks (mainly for CFF) and other issues that might cause crashes in rare circumstances. - Jam support has been removed. - In `ftview', custom LCD filter values are now normalized and balanced. Unorthodox filters are still available through the `-L' command line option. - The GUI demo programs can now be resized. - Demo programs that accept command line option `-k' can now handle function keys, too. The corresponding character codes start with 0xF1. As an example, the POSIX shell syntax (accepted by bash, ksh, and zsh) -k $'\xF3q' emulates the pressing of function key `F3' followed by key `q'. ====================================================================== CHANGES BETWEEN 2.10.1 and 2.10.2 (2020-May-09) I. IMPORTANT CHANGES - Support of WOFF2 fonts. This code contribution was Nikhil Ramakrishnan's GSoC 2019 project. II. MISCELLANEOUS - Function `FT_Get_Var_Axis_Flags' returned random data for Type 1 MM fonts. - Type 1 fonts with non-integer metrics are now supported by the new (CFF) engine introduced in FreeType 2.9. - Drop support for Python 2 in Freetype's API reference generator `docwriter' (Python >= 3.5 is required for targets `make refdoc' and `make refdoc-venv'). - Auto-hinter support for Hanifi Rohingya. - Document the `FT2_KEEP_ALIVE' debugging environment variable. - The Visual C++ (and Visual C) project files for Windows builds no longer generate libraries that contain the FreeType version in its filenames. Instead, a resource file gets used to make the libraries contain the corresponding information. - The next release will remove Jam build support. - The `ftbench' demo program has a new test for testing the `FT_Glyph_Stroke' functionality. ====================================================================== CHANGES BETWEEN 2.10.0 and 2.10.1 (2019-Jul-01) I. IMPORTANT BUG FIXES - The bytecode hinting of OpenType variation fonts was flawed, since the data in the `CVAR' table wasn't correctly applied. II. MISCELLANEOUS - Auto-hinter support for Mongolian. - For distribution, `.tar.bz2' packages are replaced with `.tar.xz' bundles. - The handling of the default character in PCF fonts as introduced in version 2.10.0 was partially broken, causing premature abortion of charmap iteration for many fonts. - If `FT_Set_Named_Instance' was called with the same arguments twice in a row, the function returned an incorrect error code the second time. - Direct rendering using FT_RASTER_FLAG_DIRECT crashed (bug introduced in version 2.10.0). - Increased precision while computing OpenType font variation instances. - The flattening algorithm of cubic Bezier curves was slightly changed to make it faster. This can cause very subtle rendering changes, which aren't noticeable by the eye, however. - The auto-hinter now disables hinting if there are blue zones defined for a `style' (i.e., a certain combination of a script and its related typographic features) but the font doesn't contain any characters needed to set up at least one blue zone. - The `ftmulti' demo program now supports multiple hidden axes with the same name tag. - `ftview', `ftstring', and `ftgrid' got a `-k' command line option to emulate a sequence of keystrokes at start-up. - `ftview', `ftstring', and `ftgrid' now support screen dumping to a PNG file. - The bytecode debugger, `ttdebug', now supports variation TrueType fonts; a variation font instance can be selected with the new `-d' command line option. ====================================================================== CHANGES BETWEEN 2.9.1 and 2.10.0 (2019-Mar-15) I. IMPORTANT CHANGES - A bunch of new functions has been added to access and process COLR/CPAL data of OpenType fonts with color-layered glyphs. FT_Palette_Data_Get Retrieve color palette data. FT_Palette_Select Select and activate a color palette for color-layered glyphs. FT_Palette_Set_Foreground_Color Set text foreground color for palette index 0xFFFF. FT_Get_Color_Glyph_Layer Get color layers for a given glyph (using an interator object). FT_Bitmap_Blend Blend one bitmap onto another with a given color. - An experimental feature is the new behaviour of the `FT_LOAD_COLOR' load flag for color-layered glyphs: Internally it sets a flag so that if `FT_Render_Glyph' is called with `FT_RENDER_MODE_NORMAL' (or `FT_Load_Glyph' with `FT_LOAD_RENDER'), a default blending of the color glyph layers will happen automatically for convenience. - As a GSoC 2018 project, Nikhil Ramakrishnan completely overhauled and modernized the API reference. II. MISCELLANEOUS - The logic for computing the global ascender, descender, and height of OpenType fonts has been slightly adjusted for consistency. . If the `useTypoMetrics' flag (i.e., bit 7 in the `fsSelection' field) in the `OS/2' table is set, use the `sTypo' fields in `OS/2' unconditionally. . Otherwise use the metrics data from the `hhea' table (if not zero). . Otherwise use the `sTypo' fields from the `OS/2' table (if not zero). . Otherwise use the `usWin' data from the `OS/2' table as a last resort. Variable fonts will apply the `MVAR' deltas to whichever metrics were picked. - `TT_Set_MM_Blend' could fail if call repeatedly with the same arguments. - The precision of handling deltas in Variation Fonts has been increased. The problem did only show up with multidimensional designspaces. - New function `FT_Library_SetLcdGeometry' to set up the geometry of LCD subpixels. - FreeType now uses the `defaultChar' property of PCF fonts to set the glyph for the undefined character at glyph index 0 (as FreeType already does for all other supported font formats). As a consequence, the order of glyphs of a PCF font if accessed with FreeType can be different now compared to previous versions. This change doesn't affect PCF font access with cmaps. - `FT_Select_Charmap' has been changed to allow parameter value `FT_ENCODING_NONE', which is valid for BDF, PCF, and Windows FNT formats to access built-in cmaps that don't have a predefined `FT_Encoding' value. - A previously reserved field in the `FT_GlyphSlotRec' structure now holds the glyph index. - On Win32 platforms, the use of `_DLL' to build the library has been replaced with `DLL_EXPORT' and `DLL_IMPORT'. - The usual round of fuzzer bug fixes to better reject malformed fonts. - `FT_Outline_New_Internal' and `FT_Outline_Done_Internal' have been removed. These two functions were public by oversight only and were never documented. - A new function `FT_Error_String' returns descriptions of error codes if configuration macro FT_CONFIG_OPTION_ERROR_STRINGS is defined. - `FT_Set_MM_WeightVector' and `FT_Get_MM_WeightVector' are new functions limited to Adobe MultiMaster fonts to directly set and get the weight vector. - Support for Position Independent Code as needed by systems that prohibit automatic address fixups, such as BREW, has been removed. [Compilation with modern compilers that use flags like `-fPIC' or `-fPIE' is not affected.] - The `ftdump' demo program has new options `-c' and `-C' to display charmaps in compact and detailed format, respectively. Option `-V' has been removed. - The `ftview', `ftstring', and `ftgrid' demo programs use a new command line option `-d' to specify the program window's width, height, and color depth. - The `ftview' demo program now displays red boxes for zero-width glyphs. - `ftglyph' has limited support to display fonts with color-layered glyphs. This will be improved later on. - `ftgrid' can now display bitmap fonts also. - The `ttdebug' demo program has a new option `-f' to select a member of a TrueType collection (TTC). - Other various improvements to the demo programs. ====================================================================== CHANGES BETWEEN 2.9 and 2.9.1 (2019-May-01) I. IMPORTANT BUG FIXES - Type 1 fonts containing flex features were not rendered correctly (bug introduced in version 2.9). - CVE-2018-6942: Older FreeType versions can crash with certain malformed variation fonts. https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2018-6942 II. MISCELLANEOUS - Bug fix: Multiple calls to `FT_Get_MM_Var' returned garbage. - The base extensions `ftlcdfil' and `ftfntfmt' are now part of the base module (and thus no longer configurable in file `modules.cfg'). - Emboldening of bitmaps didn't work correctly sometimes, showing various artifacts (bug introduced in version 2.8.1). - Use of the `freetype-config' script to get compilation and linking options is deprecated since it doesn't support cross-compiling, among other deficiencies. Instead, you should use the `pkg-config' interface. The `configure' script no longer installs `freetype-config' by default. For backward compatibility, a new configure option `--enable-freetype-config' is provided that reverts this decision. - The auto-hinter script ranges have been updated for Unicode 11. No support for new scripts have been added, however, with the exception of Georgian Mtavruli. - Support for cmake has been improved. - The next release will remove support for Position Independent Code as needed by systems that prohibit automatic address fixups, such as BREW. [Compilation with modern compilers that use flags like `-fPIC' or `-fPIE' is not affected.] ====================================================================== CHANGES BETWEEN 2.8.1 and 2.9 (2018-Jan-08) I. IMPORTANT BUG FIXES - Advance width values of variation fonts were often wrong. - More fixes for variation font support; you should update to this version if you want to support them. II. IMPORTANT CHANGES - As a GSoC project, Ewald Hew extended the new (Adobe) CFF engine to handle Type 1 fonts also, thus greatly improving the rendering of this format. This is the new default. The old engine is still available if the configuration macro `T1_CONFIG_OPTION_OLD_ENGINE' gets defined; using the `hinting-engine' property of the `type1' driver module you can then switch between the two engines. - A new function, `FT_Set_Named_Instance', can be used to set or change the current named instance. - Starting with this FreeType version, resetting variation coordinates will return to the currently selected named instance. Previously, FreeType returned to the base font (i.e., no instance set). III. MISCELLANEOUS - The `face_flags' field of the `FT_Face' structure has a new bit, `FT_FACE_FLAG_VARIATION', which is set if a variation font has been altered with `FT_Set_MM_Design_Coordinates', `FT_Set_Var_Design_Coordinates', or `FT_Set_Var_Blend_Coordinates'. - If the current face is a named instance, the new macro `FT_IS_NAMED_INSTANCE' returns true. - `FT_IS_VARIATION' is a new macro that returns true whenever a face object has been altered by `FT_Set_MM_Design_Coordinates', `FT_Set_Var_Design_Coordinates', or `FT_Set_Var_Blend_Coordinates'. - Changing the design coordinates of a variation font with `FT_Set_Var_Design_Coordinates' or `FT_Set_Var_Blend_Coordinates' does not influence the named instance index value (only `FT_Set_Named_Instance' does that). - Special PostScript names for named instances are only returned if the named instance is set with `FT_Set_Named_Instance' (and the font has corresponding entries in its `fvar' table). If `FT_IS_VARIATION' returns true, the algorithmically derived PostScript name is provided, not looking up special entries for named instances. - A new function `FT_Done_MM_Var' is provided to free the memory returned in a call to `FT_Get_MM_Var'. - On platforms using the `configure' script, the installed `ftoption.h' file now correctly reflects configuration options like `--with-harfbuzz'. - Better support to build FreeType as a DLL on Windows using Visual C. - All data specific to driver modules is now collected in a single file, `FT_DRIVER_H'. Consequently, the macros `FT_AUTOHINTER_H', `FT_CFF_DRIVER_H', `FT_TRUETYPE_DRIVER_H', and `FT_PCF_DRIVER_H' still work but are deprecated. - Some fuzzer fixes to better reject malformed fonts. - The `ftbench' demo program has a new test for opening a new face and loading some glyphs. - The `ftbench' demo program has a new option `-j' to specify the last glyph index to be used in the tests. - The `ftgrid' demo program has a new option `-n' to suppress display of named instances of variation fonts. - The `ttdebug' demo program can now show a stack trace (key `K') and switch between hexadecimal and decimal display of integers (key `I'). ====================================================================== CHANGES BETWEEN 2.8 and 2.8.1 (2017-Sep-16) I. IMPORTANT BUG FIXES - B/W hinting of TrueType fonts didn't work properly if interpreter version 38 or 40 was selected. - Some severe problems within the handling of TrueType Variation Fonts were found and fixed. - Function `FT_Set_Var_Design_Coordinates' didn't correctly handle the case with less input coordinates than axes. II. IMPORTANT CHANGES - By default, FreeType now offers high quality LCD-optimized output without resorting to ClearType techniques of resolution tripling and filtering. In this method, called Harmony, each color channel is generated separately after shifting the glyph outline, capitalizing on the fact that the color grids on LCD panels are shifted by a third of a pixel. This output is indistinguishable from ClearType with a light 3-tap filter. III. MISCELLANEOUS - Using the new function `FT_Get_Var_Axis_Flags', an application can access the `flags' field of a variation axis (introduced in OpenType version 1.8.2) - More sanity checks. - The internal representation of buffers for LCD rendering has changed (to be more precise, the amount of padding gets computed differently). Applications that use the FreeType API are not affected. - To reset all design axis values of a variation font to its default values you can now say error = FT_Set_Var_Design_Coordinates( face, 0, NULL ); This also works with functions `FT_Set_MM_Design_Coordinates' and `FT_Set_MM_Blend_Coordinates'. - FreeType now synthesizes a missing Unicode cmap for (older) TrueType fonts also if glyph names are available. - FreeType has improved handling of BDF fonts without the `POINT_SIZE', `RESOLUTION_X', or `RESOLUTION_Y' properties; the library now uses the values of the `SIZE' keyword if they are missing. Previously, `SIZE' was completely ignored, and FreeType used heuristic values instead. - Multiple calls to `FT_Bitmap_Convert' do work now as advertised. Previously, they failed with an assertion error if there was an empty bitmap between non-empty ones. - The warping option has moved from `light' to `normal' hinting where it replaces the original hinting algorithm. The `light' mode is now always void of any hinting in x-direction. - 16bit compiler support is now officially ended. We didn't provide any maintenance since many years, and given that there were no error or problem reports either it seems that it is no longer needed. - The `ftgrid' demo program can now toggle the display of grid lines with the `G' key. - The `ftgrid' demo program can toggle a different set of colors (suitable to color-blind people) with the `C' key. - The `ftgrid' demo program now supports the `-e' command line option to select a cmap. - The `ftdump' demo program has a new command line option `-t' to output the SFNT table list. ====================================================================== CHANGES BETWEEN 2.7.1 and 2.8 (2017-May-13) I. IMPORTANT CHANGES - Support for OpenType Variation Fonts is now complete. The last missing part was handling the `VVAR' and `MVAR' tables, which is available with this release. - A new function `FT_Face_Properties' allows the control of some module and library properties per font. Currently, the following properties can be handled: stem darkening, LCD filter weights, and the random seed for the `random' CFF operator. - The PCF change to show more `colorful' family names (introduced in version 2.7.1) was too radical; it can now be configured with PCF_CONFIG_OPTION_LONG_FAMILY_NAMES at compile time. If activated, it can be switched off at run time with the new pcf property `no-long-family-names'. If the `FREETYPE_PROPERTIES' environment variable is available, you can say FREETYPE_PROPERTIES=pcf:no-long-family-names=1 - Support for the following scripts has been added to the auto-hinter. Adlam, Avestan, Bamum, Buhid, Carian, Chakma, Coptic, Cypriot, Deseret, Glagolitic, Gothic, Kayah, Lisu, N'Ko, Ol Chiki, Old Turkic, Osage, Osmanya, Saurashtra, Shavian, Sundanese, Tai Viet, Tifinagh, Unified Canadian Syllabics, Vai II. IMPORTANT BUG FIXES - `Light' auto-hinting mode no longer uses TrueType metrics for TrueType fonts. This bug was introduced in version 2.4.6, causing horizontal scaling also. Almost all GNU/Linux distributions (with Fedora as a notable exception) disabled the corresponding patch for good reasons; chances are thus high that you won't notice a difference. If optical backward compatibility for legacy applications is necessary, you might enable the AF_CONFIG_OPTION_TT_SIZE_METRICS configuration option. However, it is strongly recommended to avoid that, adjusting font sizes instead. - Global size metrics values in the `FT_Size_Metrics' structure can be different for TrueType fonts. Reason is that in older FreeType versions the metrics were rounded differently to integer pixels compared to all other font formats, yielding an inconsistent behaviour if you used non-native hinting. Starting with this version, global size metrics for TrueType fonts are handled the same as other font formats: `ascender' gets rounded up, `descender' gets rounded down, `height' gets normally rounded, and `max_advance' gets normally rounded, too. If you need more precise values of (global) ascender, descender, height, or `max_advance', please take the corresponding values from the `FT_Face' structure and scale them manually. - If a TrueType font gets loaded with FT_LOAD_NO_HINTING, FreeType now scales the font linearly again (bug introduced in version 2.4.6). - CVE-2017-8105, CVE-2017-8287: Older FreeType versions have out-of-bounds writes caused by heap-based buffer overflows related to Type 1 fonts. https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2017-8105 https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2017-8287 III. MISCELLANEOUS - A new function `FT_Set_Default_Properties' has been added to parse the `FREETYPE_PROPERTIES' environment variable (previously, it was internal only). `FT_Init_FreeType' always call this function, but `FT_New_Library' does not (similar to `FT_Add_Default_Modules'). - To be in sync with OpenType version 1.7 and newer, macros FT_PARAM_TAG_IGNORE_PREFERRED_FAMILY, FT_PARAM_TAG_IGNORE_PREFERRED_SUBFAMILY, TT_NAME_ID_PREFERRED_FAMILY TT_NAME_ID_PREFERRED_SUBFAMILY are renamed to FT_PARAM_TAG_IGNORE_TYPOGRAPHIC_FAMILY, FT_PARAM_TAG_IGNORE_TYPOGRAPHIC_SUBFAMILY, TT_NAME_ID_TYPOGRAPHIC_FAMILY TT_NAME_ID_TYPOGRAPHIC_SUBFAMILY The old macro names are deprecated (but still available). - Support for SFNT `name' tables has been improved. . Format 1 `name' tables are now supported. Use new function `FT_Get_Sfnt_LangTag' to access associated language tags. . Language, encoding, and name IDs have been updated to OpenType version 1.8.1. - The new CFF engine now handles the `random' operator. All CFF opcodes are now supported. - The CFF module has a new property `random-seed' to control the pseudo-random number generation for the `random' operator. - The `freetype-config' script is now a wrapper of `pkg-config' if this program is available in the path. - FT_LOAD_TARGET_LCD is now a variant of FT_LOAD_TARGET_LIGHT; this should provide better rendering results. - A mode to display light auto-hinting with subpixel positioning has been added to `ftdiff'. ====================================================================== CHANGES BETWEEN 2.7 and 2.7.1 (2016-Dec-30) I. IMPORTANT CHANGES - Support for the new CFF2 font format as introduced with OpenType 1.8 has been contributed by Dave Arnolds from Adobe. - Preliminary support for variation fonts as specified in OpenType 1.8 (in addition to the already existing support for Adobe's MM and Apple's GX formats). Dave Arnolds contributed handling of advance width change variation; more will come in the next version. II. IMPORTANT BUG FIXES - Handling of raw CID fonts was partially broken (bug introduced in 2.6.4). - CVE-2016-10328: Older FreeType versions had an out-of-bounds write caused by a heap-based buffer overflow related to the CFF fonts. https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2016-10328 III. MISCELLANEOUS - Some limits for TrueType bytecode execution have been tightened to speed up FreeType's handling of malformed fonts, in particular to quickly abort endless loops. - The number of twilight points can no longer be set to an arbitrarily large value. - The total number of jump opcode instructions (like JMPR) with negative arguments is dynamically restricted; the same holds for the total number of iterations in LOOPCALL opcodes. The dynamic limits are based on the number of points in a glyph and the number of CVT entries. Please report if you encounter a font where the selected values are not adequate. - PCF family names are made more `colorful'; they now include the foundry and information whether they contain wide characters. For example, you no longer get `Fixed' but rather `Sony Fixed' or `Misc Fixed Wide'. - A new function `FT_Get_Var_Blend_Coordinates' (with its alias name `FT_Get_MM_Blend_Coordinates') to retrieve the normalized blend coordinates of the currently selected variation instance has been added to the Multiple Masters interface. - A new function `FT_Get_Var_Design_Coordinates' to retrieve the design coordinates of the currently selected variation instance has been added to the Multiple Masters interface. - A new load flag `FT_LOAD_BITMAP_METRICS_ONLY' to retrieve bitmap information without loading the (embedded) bitmap itself. - Retrieving advance widths from bitmap strikes (using `FT_Get_Advance' and `FT_Get_Advances') have been sped up. - The usual round of fuzzer fixes to better reject malformed fonts. - The `ftmulti' demo program can now switch engines with key `H'. - The `ftstring' demo program can now show some built-in, non-latin sample strings (to be selected with the TAB key). - The `ftview' demo program can now switch between a font's charmaps using the TAB key. ====================================================================== CHANGES BETWEEN 2.6.5 and 2.7 (2016-Sep-08) I. IMPORTANT CHANGES - As announced earlier, the 2.7.x series now uses the new subpixel hinting mode as the default, emulating a modern version of ClearType. This change inevitably leads to different rendering results, and you might change the `TT_CONFIG_OPTION_SUBPIXEL_HINTING' configuration option to adapt it to your taste (or use the new `FREETYPE_PROPERTIES' environment variable). See the corresponding entry below for version 2.6.4, which gives more information. - A new option `FT_CONFIG_OPTION_ENVIRONMENT_PROPERTIES' has been introduced. If set (which is the default), an environment variable `FREETYPE_PROPERTIES' can be used to control driver properties. Example: FREETYPE_PROPERTIES=truetype:interpreter-version=35 \ cff:no-stem-darkening=1 \ autofitter:warping=1 This allows to select, say, the subpixel hinting mode at runtime for a given application. See file `ftoption.h' for more. II. IMPORTANT BUG FIXES - After loading a named instance of a GX variation font, the `face_index' value in the returned `FT_Face' structure now correctly holds the named instance index in the upper 16bits as documented. III. MISCELLANEOUS - A new macro `FT_IS_NAMED_INSTANCE' to test whether a given face is a named instance. - More fixes to GX font handling. - Apple's `GETVARIATION' bytecode operator (needed for GX variation font support) has been implemented. - Another round of fuzzer fixes, mainly to reject invalid fonts faster. - Handling of raw CID fonts was broken (bug introduced in version 2.6.4). - The smooth rasterizer has been streamlined to make it faster by approx. 20%. - The `ftgrid' demo program now understands command line option `-d' to give start-up design coordinates. - The `ftdump' demo program has a new command line option `-p' to dump TrueType bytecode instructions. ====================================================================== CHANGES BETWEEN 2.6.4 and 2.6.5 (2016-Jul-12) I. IMPORTANT BUG FIXES - Compilation works again on Mac OS X (bug introduced in version 2.6.4). II. IMPORTANT CHANGES - The new subpixel hinting mode is now disabled by default; it will be enabled by default in the forthcoming 2.7.x series. Main reason for reverting this feature is the principle of least surprise: a sudden change in appearance of all fonts (even if the rendering improves for almost all recent fonts) should not be expected in a new micro version of a series. ====================================================================== CHANGES BETWEEN 2.6.3 and 2.6.4 (2016-Jul-05) I. IMPORTANT CHANGES - A new subpixel hinting mode has been contributed by Nikolaus Waxweiler, which is now the default rendering mode for TrueType fonts. It implements (almost everything of) version 40 of the bytecode engine. The existing code base in FreeType (the `Infinality code') was stripped to the bare minimum and all configurability removed in the name of speed and simplicity. The configurability was mainly aimed at legacy fonts like Arial, Times New Roman, or Courier. [Legacy fonts are fonts that modify vertical stems to achieve clean black-and-white bitmaps.] The new mode focuses on applying a minimal set of rules to all fonts indiscriminately so that modern and web fonts render well while legacy fonts render okay. Activation of the subpixel hinting support can be controlled with the `TT_CONFIG_OPTION_SUBPIXEL_HINTING' configuration option at compile time: If set to value 1, you get the old Infinality mode (which was never the default due to its slowness). Value 2 activates the new subpixel hinting mode, and value 3 activates both. The default is value 2. At run time, you can select the subpixel hinting mode with the `interpreter-version' property (provided you have compiled in the corresponding hinting mode); see `ftttdrv.h' for more. - Support for the following scripts has been added to the auto-hinter. Armenian, Cherokee, Ethiopic, Georgian, Gujarati, Gurmukhi, Malayalam, Sinhala, Tamil II. MISCELLANEOUS - Type 42 fonts as created by LilyPond are now supported. - Minor rendering improvements in the auto-hinter. - For experimental reasons, the old CFF engine now supports all CFF operators except `random', including the deprecated Multiple Masters instructions. This allows the display of fonts like `ITCGaramondMM-It.otf' (without font variations, though). - Another round of fixes to improve handling of invalid fonts. - The `ftgrid' demo program now displays the rendered pixels also; this can be switched off with the `b' key. Selection of various LCD filtering modes can be done with the `L' key. - The demo programs have been extended to allow selection of all available TrueType bytecode engines. - A very early beta version of a new, Qt based demo program called `ftinspect' is part of the source code bundle; it will eventually supersede the other demo programs. Currently, you have to compile it manually with `qmake; make'; note that many features are still missing. ====================================================================== CHANGES BETWEEN 2.6.2 and 2.6.3 (2016-Feb-08) I. IMPORTANT CHANGES - Khmer, Myanmar, Bengali, and Kannada script support has been added to the auto-hinter. II. MISCELLANEOUS - Better support of Indic scripts like Devanagari by using a top-to-bottom hinting flow. - All FreeType macros starting with two underscores have been renamed to avoid a violation of both the C and C++ standards. Example: Header macros of the form `__FOO_H__' are now called `FOO_H_'. In most cases, this should be completely transparent to the user. The exception to this is `__FTERRORS_H__', which must be sometimes undefined by the user to get FreeType error strings: Both this form and the new `FTERRORS_H_' macro are accepted for backward compatibility. - Minor improvements mainly to the Type 1 driver. - The new CFF engine now supports all Type 2 operators except `random'. - The macro `_STANDALONE_', used for compiling the B/W and smooth rasterizers as stand-alone modules, has been renamed to `STANDALONE_', since macro names starting with an underscore and followed by an uppercase letter are reserved in both C and C++. - Function `FT_Library_SetLcdFilterWeights' now also activates custom LCD filter weights (instead of just adjusting them). - Support for `unpatented hinting' has been completely removed: Consequently, the two functions `FT_Face_CheckTrueTypePatents' and `FT_Face_SetUnpatentedHinting' now return always false, doing nothing. - The `ftgamma' demo program has been modernized; the gamma grid display has been moved from `ftview' to this program. - In `ftview', it is now possible to cycle through the available LCD filtering modes. ====================================================================== CHANGES BETWEEN 2.6.1 and 2.6.2 (2015-Nov-28) I. IMPORTANT CHANGES - The auto-hinter now supports stem darkening, to be controlled by the new `no-stem-darkening' and `darkening-parameters' properties. This is an experimental feature contributed by Nikolaus Waxweiler, and the interface might change in a future release. - By default, stem darkening is now switched off (for both the CFF engine and the auto-hinter). The main reason is that you need linear alpha blending and gamma correction to get correct rendering results, and the latter is not yet available in most freely available rendering stacks like X11. Applying stem darkening without proper gamma correction leads to far too dark rendering results. - The meaning of `FT_RENDER_MODE_LIGHT' has been slightly modified. It now essentially means `no hinting along the horizontal axis'; in particular, no change of glyph advance widths. Consequently, the auto-hinter is used for all scalable font formats except for CFF. It is planned that other font-specific rendering engines (TrueType, Type 1) will follow. II. MISCELLANEOUS - The default LCD filter has been changed to be normalized and color-balanced. - For better compatibility with FontConfig, function `FT_Library_SetLcdFilter' accepts a new enumeration value `FT_LCD_FILTER_LEGACY1' (which has the same meaning as `FT_LCD_FILTER_LEGACY'). - A large number of bugs have been detected by using the libFuzzer framework, which should further improve handling of invalid fonts. Thanks again to Kostya Serebryany and Bungeman! - `TT_CONFIG_OPTION_MAX_RUNNABLE_OPCODES', a new configuration option, controls the maximum number of executed opcodes within a bytecode program. You don't want to change this except for very special situations (e.g., making a library fuzzer spend less time to handle broken fonts). - The smooth renderer has been made faster. - The `ftstring' demo program now supports subpixel rendering; use key `l' to cycle through the LCD modes. - The `ftstring' demo program now supports color rendering; use the `space' key to cycle through various color combinations. - The graphical demo programs now use a default gamma value of 1.8 (instead of 1.2). ====================================================================== CHANGES BETWEEN 2.6 and 2.6.1 (2015-Oct-04) I. IMPORTANT BUG FIXES - It turned out that for CFFs only the advance widths should be taken from the `htmx' table, not the side bearings. This bug, introduced in version 2.6.0, makes it necessary to upgrade if you are using CFFs; otherwise, you get cropped glyphs with GUI interfaces like GTK or Qt. - Accessing Type 42 fonts returned incorrect results if the glyph order of the embedded TrueType font differs from the glyph order of the Type 42 charstrings table. II. IMPORTANT CHANGES - The header file layout has been changed (again), moving all header files except `ft2build.h' into a subdirectory tree. Doing so reduces the possibility of header file name clashes (e.g., FTGL's `FTGlyph.h' with FreeType's `ftglyph.h') on case insensitive file systems like Mac OS X or Windows. Applications that use (a) the `freetype-config' script or FreeType's `freetype2.pc' file for pkg-config to get the include directory for the compiler, and (b) the documented way for header inclusion like #include <ft2build.h> #include FT_FREETYPE_H ... don't need any change to the source code. - Simple access to named instances in GX variation fonts is now available (in addition to the previous method via FreeType's MM interface). In the `FT_Face' structure, bits 16-30 of the `face_index' field hold the current named instance index for the given face index, and bits 16-30 of `style_flags' contain the number of instances for the given face index. `FT_Open_Face' and friends also understand the extended bits of the face index parameter. You need to enable TT_CONFIG_OPTION_GX_VAR_SUPPORT for this new feature. Otherwise, bits 16-30 of the two fields are zero (or are ignored). - Lao script support has been added to the auto-hinter. III. MISCELLANEOUS - The auto-hinter's Arabic script support has been enhanced. - Superscript-like and subscript-like glyphs as used by various phonetic alphabets like the IPA are now better supported by the auto-hinter. - The TrueType bytecode interpreter now runs slightly faster. - Improved support for builds with cmake. - The function `FT_CeilFix' now always rounds towards plus infinity. - The function `FT_FloorFix' now always rounds towards minus infinity. - A new load flag `FT_LOAD_COMPUTE_METRICS' has been added; it makes FreeType ignore pre-computed metrics, as needed by font validating or font editing programs. Right now, only the TrueType module supports it to ignore data from the `hdmx' table. - Another round of bug fixes to better handle broken fonts, found by Kostya Serebryany <kcc@google.com>. ====================================================================== CHANGES BETWEEN 2.5.5 and 2.6 (2015-Jun-07) I. IMPORTANT CHANGES - Behdad Esfahbod contributed code for improved thread-safety, which results in the following model. * An `FT_Face' object can only be safely used from one thread at a time. * An `FT_Library' object can now be used without modification from multiple threads at the same time. * `FT_Face' creation and destruction with the same `FT_Library' object can only be done from one thread at a time. One can use a single `FT_Library' object across threads as long as a mutex lock is used around `FT_New_Face' and `FT_Done_Face'. Any calls to `FT_Load_Glyph' and similar API are safe and do not need the lock to be held as long as the same `FT_Face' is not used from multiple threads at the same time. - Thai script support has been added to the auto-hinter. - Arabic script support has been added to the auto-hinter. - Following OpenType version 1.7, advance widths and side bearing values in CFFs (wrapped in an SFNT structure) are now always taken from the `hmtx' table. - Following OpenType version 1.7, the PostScript font name of a CFF font (wrapped in an SFNT structure) is now always taken from the `name' table. This is also true for OpenType Collections (i.e., TTCs using CFFs subfonts instead of TTFs), where it may have a significant difference. - Fonts natively hinted for ClearType are now supported, properly handling selector index 3 of the INSTCTRL bytecode instruction. - Major improvements to the GX TrueType variation font handling. II. MISCELLANEOUS - A new auto-hinter property `warping' can switch on and off the warping code if this experimental feature is compiled in (by defining the AF_CONFIG_OPTION_USE_WARPER configuration option; by default this option is now enabled but warping is switched off). The AF_CONFIG_OPTION_USE_WARPER option itself is an old feature, available since 2006. Warping only works in `light' auto-hinting mode. The idea of the code is to slightly scale and shift a glyph along the non-hinted dimension (which is usually the horizontal axis) so that as much of its segments are aligned (more or less) to the grid. To find out a glyph's optimal scaling and shifting value, various parameter combinations are tried and scored. See file `ftautoh.h' for more; the demo programs `ftdiff', `ftview', and `ftgrid' can toggle warping with key `w'. - Some fields in the `FTC_ImageTypeRec' structure have been changed from signed to unsigned type, which better reflects the actual usage. It is also an additional means to protect against malformed input. This change doesn't break the ABI; however, it might cause compiler warnings. - Function `FT_Bitmap_New' has been renamed to `FT_Bitmap_Init', since this name better reflects its function. For backward compatibility, the old function name is still available. - Function `FT_Get_X11_Font_Format' has been renamed to `FT_Get_Font_Format', since this name better reflects its function. For backward compatibility, the old function name is still available. Additionally, the header file macro for this function has been renamed to `FT_FONT_FORMATS_H' (the old name `FT_XFREE86_H' is retained for backward compatibility). - Various improvements to the `ftgrid' demo program. . It can now display GX and MM fonts while interactively manipulating the axes (with keys F2, F3, and F4). . Anti-aliasing rendering modes can now be selected (with keys F5 and F6). . The display of point numbers can be toggled with key `D'. - Various improvements to the `ftdump' demo program. . It now displays information on MM and GX variation axes. . New command line option `-u' makes it output data in utf-8 encoding. - The `ftmulti' demo program can now handle up to six MM or GX axes. ====================================================================== CHANGES BETWEEN 2.5.4 and 2.5.5 (2014-Dec-30) I. IMPORTANT BUG FIXES - Handling of uncompressed PCF files works again (bug introduced in version 2.5.4). ====================================================================== CHANGES BETWEEN 2.5.3 and 2.5.4 (2014-Dec-06) I. IMPORTANT BUG FIXES - A variant of vulnerability CVE-2014-2240 was identified (cf. https://savannah.nongnu.org/bugs/?43661) and fixed in the new CFF driver. All users should upgrade. - The new auto-hinter code using HarfBuzz crashed for some invalid fonts. - Many fixes to better protect against malformed input. II. IMPORTANT CHANGES - Full auto-hinter support of the Devanagari script. - Experimental auto-hinter support of the Telugu script. - CFF stem darkening behaviour can now be controlled at build time using the eight macros CFF_CONFIG_OPTION_DARKENING_PARAMETER_{X,Y}{1,2,3,4} . - Some fields in the `FT_Bitmap' structure have been changed from signed to unsigned type, which better reflects the actual usage. It is also an additional means to protect against malformed input. This change doesn't break the ABI; however, it might cause compiler warnings. III. MISCELLANEOUS - Improvements to the auto-hinter's algorithm to recognize stems and local extrema. - Function `FT_Get_SubGlyph_Info' always returned an error even in case of success. - Version 2.5.1 introduced major bugs in the cjk part of the auto-hinter, which are now fixed. - The `FT_Sfnt_Tag' enumeration values have been changed to uppercase, e.g. `FT_SFNT_HEAD'. The lowercase variants are deprecated. This is for orthogonality with all other enumeration (and enumeration-like) values in FreeType. - `cmake' now supports builds of FreeType as an OS X framework and for iOS. - Improved project files for vc2010, introducing a property file. - The documentation generator for the API reference has been updated to produce better HTML code (with proper CSS). At the same time, the documentation got a better structure. - The FT_LOAD_BITMAP_CROP flag is obsolete; it is not used by any driver. - The TrueType DELTAP[123] bytecode instructions now work in subpixel hinting mode as described in the ClearType whitepaper (i.e., for touched points in the non-subpixel direction). - Many small improvements to the internal arithmetic routines. ====================================================================== CHANGES BETWEEN 2.5.2 and 2.5.3 (2014-Mar-06) I. IMPORTANT BUG FIXES - A vulnerability (CVE-2014-2240) was identified and fixed in the new CFF driver (cf. https://savannah.nongnu.org/bugs/?41697). All users should upgrade. - More bug fixes related to correct positioning of composite glyphs. - Many fixes to better protect against malformed input. II. IMPORTANT CHANGES - FreeType can now use the HarfBuzz library to greatly improve the auto-hinting of fonts that use OpenType features: Many glyphs that are part of such features but don't have cmap entries are now handled properly, for example small caps or superscripts. Define the configuration macro FT_CONFIG_OPTION_USE_HARFBUZZ to activate HarfBuzz support. You need HarfBuzz version 0.9.19 or newer. Note that HarfBuzz depends on FreeType; this currently causes a chicken-and-egg problem that can be solved as follows in case HarfBuzz is not yet installed on your system. 1. Compile and install FreeType without the configuration macro FT_CONFIG_OPTION_USE_HARFBUZZ. 2. Compile and install HarfBuzz. 3. Define macro FT_CONFIG_OPTION_USE_HARFBUZZ, then compile and install FreeType again. With FreeType's `configure' script the procedure boils down to configure, build, and install FreeType, then configure, compile, and install HarfBuzz, then configure, compile, and install FreeType again (after executing `make distclean'). - All libraries FreeType depends on are now checked using the `pkg-config' configuration files first, followed by alternative methods. - The new value `auto' for the various `--with-XXX' library options (for example `--with-harfbuzz=auto') makes the `configure' script automatically link to the libraries it finds. This is now the default. - In case FreeType's `configure' script can't find a library, you can pass environment variables to circumvent pkg-config, and those variables have been harmonized as a consequence of the changes mentioned above: LIBZ -> removed; use LIBZ_CFLAGS and LIBZ_LIBS LIBBZ2 -> removed; use BZIP2_CFLAGS and BZIP2_LIBS LIBPNG_LDFLAGS -> LIBPNG_LIBS `./configure --help' shows all available environment variables. - The `freetype-config' script now understands option `--static' to emit static linking information. ====================================================================== CHANGES BETWEEN 2.5.1 and 2.5.2 (2013-Dec-08) I. IMPORTANT BUG FIXES - Improving the display of some broken TrueType fonts introduced a bug that made FreeType crash on some popular (but not fully conformant) fonts like `ahronbd.ttf'. - Another round of improvements to correct positioning and hinting of composite glyphs in TrueType fonts. II. MISCELLANEOUS - Version 2.5.1 introduced a bug in handling embedded bitmap strikes of TrueType fonts, causing garbage display under some circumstances. - The `ftgrid' demo program couldn't be compiled in non-development builds. ====================================================================== CHANGES BETWEEN 2.5 and 2.5.1 (2013-Nov-25) I. IMPORTANT BUG FIXES - For some WinFNT files, the last glyph wasn't displayed but incorrectly marked as invalid. - The vertical size of glyphs was incorrectly set after a call to `FT_GlyphSlot_Embolden', resulting in clipped glyphs. - Many fields of the `PCLT' table in SFNT based fonts (if accessed with `FT_Get_Sfnt_Table') were computed incorrectly. - In TrueType fonts, hinting of composite glyphs could sometimes deliver incorrect positions of components or even distorted shapes. II. IMPORTANT CHANGES - WOFF font format support has been added. - The auto-hinter now supports Hebrew. Greek and Cyrillic support has been improved. - Support for the forthcoming `OS/2' SFNT table version 5, as can be found e.g. in the `Sitka' font family for Windows 8.1. - The header file layout has been changed. After installation, all files are now located in `<prefix>/include/freetype2'. Applications that use (a) `freetype-config' or FreeType's `pkg-config' file to get the include directory for the compiler, and (b) the documented way for header inclusion like #include <ft2build.h> #include FT_FREETYPE_H ... don't need any change to the source code. III. MISCELLANEOUS - The stem darkening feature of the new CFF engine can now be fine-tuned with the new `darkening-parameters' property. - `ftgrid' has been updated to toggle various engines with the `H' key, similar to `ftview' and `ftdiff'. - The functionality of `ttdebug' has been greatly enhanced. . It now displays twilight, storage, and control value data; key `T' shows the twilight point table, key `S' the storage data, and key `C' the control value table. . Some keys have been reassigned from lowercase to their uppercase equivalents; for example `q' to quit the program is now `Q'. . Key `f' finishes the current function. . Key `R' restarts the debugger. . Keys `b' and `p' set a breakpoint. . Key `B' provides a function call backtrace. - Better support of ARMv7 and x86_64 processors. - Apple's `sbix' color bitmap format is now supported. - Improved auto-hinter rendering for many TrueType fonts, especially in the range 20-40ppem. - A new face flag `FT_FACE_FLAG_COLOR' has been added (to be accessed with the macro `FT_HAS_COLOR'). - `FT_Gzip_Uncompress' (modeled after zlib's `uncompress' function) has been added; this is a by-product of the newly added WOFF support. - Support for a build with `cmake' has been contributed by John Cary <cary@txcorp.com>. - Support for x64 builds with Visual C++ has been contributed by Kenneth Miller <kennethadammiller@yahoo.com> - Manual pages for most demo programs have been added. - The GETINFO bytecode instruction for TrueType fonts was buggy if used to retrieve subpixel hinting information. It was necessary to set selector bit 6 to get results for selector bits 7-10, which is wrong. - Improved computation of emulated vertical metrics for TrueType fonts. - Fixed horizontal start-up position of vertical phantom points in TrueType bytecode. ====================================================================== CHANGES BETWEEN 2.4.12 and 2.5 (2013-Jun-19) I. IMPORTANT BUG FIXES - The cache manager function `FTC_Manager_Reset' didn't flush the cache. II. IMPORTANT CHANGES - Behdad Esfahbod (on behalf of Google) contributed support for color embedded bitmaps (eg. color emoji). A new load flag, FT_LOAD_COLOR, makes FreeType load color embedded-bitmaps, following this draft specification https://color-emoji.googlecode.com/git/specification/v1.html which defines two new SFNT tables, `CBDT' and `CBLC' (named and modeled after `EBDT' and `EBLC', respectively). The color bitmaps are stored in the new FT_PIXEL_MODE_BGRA format to represent BGRA pre-multiplied sRGB images. If PNG support is available, PNG color images as defined in the same proposed specification are supported also. Note that color bitmaps are converted to grayscale if client didn't ask for color. - As announced in the previous release, the old FreeType CFF engine is now disabled by default. It can be conditionally compiled by defining the configuration macro CFF_CONFIG_OPTION_OLD_ENGINE. - As announced in the previous release, all code related to macro FT_CONFIG_OPTION_OLD_INTERNALS has been removed, thus becoming obsolete. III. MISCELLANEOUS - The property API (`FT_Property_Get' and `FT_Property_Set') is now declared as stable. The exception, however, are the experimental auto-hinter properties `glyph-to-script-map' and `fallback-script' which are subject to change in a forthcoming release. - `ftview' has been updated to support color embedded bitmaps; it can be toggled on and off with key `c'. The small cache toggle is now key `K'. - It is now possible to control the version of the TrueType hinting engine using the new `interpreter-version' property of the `truetype' module: Versions 35 and 38 (the default) are supported, which roughly corresponds to disable and enable subpixel hinting support, respectively. In both `ftview' and `ftdiff', switching between the two versions can be done with key `H'. In the `ftbench' demo program, command line option `-H' has been extended to activate the non-default interpreter version. - The `ttdebug' program has been further improved. In particular, it accepts a new command line option `-H' to select the hinting engine. - `ftdump's verbose option has been renamed to `-V'. For all demo programs, `-v' now shows version information. - Another round of TrueType subpixel hinting fixes. - The `apinames' tool can now create an import file for NetWare. - 64bit compilation of the new CFF engine was buggy. - Some fixes to improve robustness in memory-tight situations. ====================================================================== CHANGES BETWEEN 2.4.11 and 2.4.12 (2013-May-08) - We have another CFF parsing and hinting engine! Written by Dave Arnold <darnold@adobe.com>, this work has been contributed by Adobe in collaboration with Google. It is vastly superior to the old CFF engine, and it will replace it in the next release. Right now, it is still off by default, and you have to explicitly select it using the new `hinting-engine' property of the cff driver: ... #include FT_MODULE_H #include FT_CFF_DRIVER_H FT_Library library; int engine = FT_CFF_HINTING_ADOBE; ... FT_Property_Set( library, "cff", "hinting-engine", &engine ); The code has a (mature) beta status; we encourage all users to test it and report any problems. In case you want to activate the new CFF engine unconditionally, apply this patch: --- snip --- diff --git a/src/cff/cffobjs.c b/src/cff/cffobjs.c index ebcf189..3f2ce6b 100644 --- a/src/cff/cffobjs.c +++ b/src/cff/cffobjs.c @@ -1056,7 +1056,7 @@ /* set default property values */ - driver->hinting_engine = FT_CFF_HINTING_FREETYPE; + driver->hinting_engine = FT_CFF_HINTING_ADOBE; driver->no_stem_darkening = FALSE; return FT_Err_Ok; --- snip --- - The macro FT_CONFIG_OPTION_OLD_INTERNALS is no longer set by default. In the next release, we will completely remove the associated code. Please update your programs in case you are still using this macro. II. MISCELLANEOUS - The (top-level) `configure' script now respects the MAKE environment variable to specify a `make' binary. For backward compatibility, GNUMAKE still overrides MAKE, though. - The `ftview' and `ftdiff' demo programs have been redesigned, showing more options permanently on the screen, among other minor improvements. - Using the `H' key, it is now possible to select the CFF engine in both `ftview' and `ftdiff'. - The new command line option `-H' for `ftbench' selects the Adobe CFF engine. - It is now possible to directly select the LCD rendering mode with the keys `A'-`F' in `ftview'. The key mapping for cycling through LCD modes has been changed from `K' and `L' to `k' and `l', and toggling custom LCD filtering is no longer mapped to key `F' but to key `L'. - In `ftdiff', key `x' toggles between layout modes: Either use the advance width (this is new and now the default) or the bounding box information to determine line breaks. - For all demo tools, the new command line option `-v' shows the version. - For the demo tools with a GUI, the new command line options `-w' and `-h' select the width and the height of the output window, respectively. - The `ttdebug' program was broken and has been reactivated. Note that this program is not compiled by default. ====================================================================== CHANGES BETWEEN 2.4.10 and 2.4.11 (2012-Dec-20) I. IMPORTANT BUG FIXES - Some vulnerabilities in the BDF implementation have been fixed. Users of this font format should upgrade. II. IMPORTANT CHANGES - Subpixel hinting support has been contributed by Infinality, based on Greg Hitchcock's whitepaper at https://www.microsoft.com/typography/cleartype/truetypecleartype.aspx Originally, it was a separate patch available from https://web.archive.org/web/20150710073951/http://www.infinality.net:80/blog/ and which has been integrated. Note that ClearType support is not completely implemented! In particular, full support for the options `compatible_widths', `symmetrical_smoothing, and `bgr' (via the GETINFO bytecode instruction) is missing. Activation of subpixel hinting support can be controlled with the `TT_CONFIG_OPTION_SUBPIXEL_HINTING' configuration option; it is switched off by default. This feature is still experimental; we welcome test reports! - Support for OpenType collections (OTC) has been added. - Pure CFF fonts within an SFNT wrapper are now supported. III. MISCELLANEOUS - Minor rendering improvements to the auto-hinter. - `FT_GlyphSlot_Oblique' now uses a shear angle of 12°. - Experimental support to handle `property modules', for example to control the behaviour of the auto-hinter. The API consists of two new functions, `FT_Property_Set' and `FT_Property_Get'. The code is still subject to change and should not be used for production. - The `ftdiff' demo program now supports UTF-8 encoded input files for option `-f'. - Using keys `r' and `R', you can now adjust the stroker radius in the `ftview' demo program. - Other, minor fixes and improvements. ====================================================================== CHANGES BETWEEN 2.4.9 and 2.4.10 (2012-Jun-15) I. IMPORTANT BUG FIXES - Incremental glyph loading as needed by ghostscript was broken. II. MISCELLANEOUS - A new function `FT_Outline_EmboldenXY', contributed by Alexei Podtelezhnikov. - In the `ftview' demo program, key `e' has been replaced with `x' and `y' to embolden in the horizontal and vertical direction, respectively. - The glyph spacing computation in `FT_GlyphSlot_Embolden' (and similar code in `ftview') has been improved. - Minor improvements to the TrueType bytecode interpreter and glyph loader, the auto-hinter, and the B/W rasterizer. ====================================================================== CHANGES BETWEEN 2.4.8 and 2.4.9 (2012-Mar-08) I. IMPORTANT BUG FIXES - Another round of fixes to better handle invalid fonts. Many of them are vulnerabilities (see CVE-2012-1126 up to CVE-2012-1144 and SA48320) so all users should upgrade. II. MISCELLANEOUS - The `ENCODING -1 <n>' format of BDF fonts is now supported. - For BDF fonts, support for the whole Unicode encoding range has been added. - Better TTF support for x_ppem != y_ppem. - `FT_Get_Advances' sometimes returned bogus values. - The demo programs no longer recognize and handle default suffixes; you now have to always specify the complete font name. - Better rendering and LCD mode cycling added to `ftview'. ====================================================================== CHANGES BETWEEN 2.4.7 and 2.4.8 (2011-Nov-14) I. IMPORTANT BUG FIXES - Some vulnerabilities in handling CID-keyed PostScript fonts have been fixed; see CVE-2011-3439. II. MISCELLANEOUS - Chris Liddell contributed a new API, `FT_Get_PS_Font_Value', to retrieve most of the dictionary keys in Type 1 fonts. ====================================================================== CHANGES BETWEEN 2.4.6 and 2.4.7 (2011-Oct-18) I. IMPORTANT BUG FIXES - Some vulnerabilities in handling Type 1 fonts have been fixed; see CVE-2011-3256. II. MISCELLANEOUS - FreeType now properly handles ZapfDingbats glyph names while constructing a Unicode character map (for fonts which don't have one). ====================================================================== CHANGES BETWEEN 2.4.5 and 2.4.6 (2011-Jul-29) I. IMPORTANT BUG FIXES - For TrueType based fonts, the ascender and descender values were incorrect sometimes (off by a pixel if the ppem value was not a multiple of 5). Depending on the use you might now experience a different layout; the change should result in better, more consistent line spacing. - Fix CVE-2011-0226 which causes a vulnerability while handling Type 1 fonts. - BDF fonts containing glyphs with negative values for ENCODING were incorrectly rejected. This bug has been introduced in FreeType version 2.2.0. - David Bevan contributed a major revision of the FreeType stroker code: . The behaviour of FT_STROKER_LINEJOIN_BEVEL has been corrected. . A new line join style, FT_STROKER_LINEJOIN_MITER_FIXED, has been introduced to support PostScript and PDF miter joins. . FT_STROKER_LINEJOIN_MITER_VARIABLE has been introduced as an alias for FT_STROKER_LINEJOIN_MITER. . Various stroking glitches has been fixed. II. MISCELLANEOUS - SFNT bitmap fonts which contain an outline glyph for `.notdef' only no longer set the FT_FACE_FLAG_SCALABLE flag. ====================================================================== CHANGES BETWEEN 2.4.4 and 2.4.5 (2011-Jun-25) I. IMPORTANT BUG FIXES - A rendering regression for second-order Bézier curves has been fixed, introduced in 2.4.3. II. IMPORTANT CHANGES - If autohinting is not explicitly disabled, FreeType now uses the autohinter if a TrueType based font doesn't contain native hints. - The load flag FT_LOAD_IGNORE_GLOBAL_ADVANCE_WIDTH has been made redundant and is simply ignored; this means that FreeType now ignores the global advance width value in TrueType fonts. III. MISCELLANEOUS - `FT_Sfnt_Table_Info' can now return the number of SFNT tables of a font. - Support for PCF files compressed with bzip2 has been contributed by Joel Klinghed. To make this work, the OS must provide a bzip2 library. - Bradley Grainger contributed project and solution files in Visual Studio 2010 format. - Again some fixes to better handle broken fonts. - Some improvements to the B/W rasterizer. - Fixes to the cache module to improve robustness. - Just Fill Bugs contributed (experimental) code to compute blue zones for CJK Ideographs, improving the alignment of horizontal stems at the top or bottom edges. - The `ftgrid' demo program can now display autohinter segments, to be toggled on and off with key `s'. ====================================================================== CHANGES BETWEEN 2.4.3 and 2.4.4 (2010-Nov-28) I. IMPORTANT BUG FIXES - UVS support (TrueType/OpenType cmap format 14) support is fixed. This regression has been introduced in version 2.4.0. II. MISCELLANEOUS - Detect tricky fonts (e.g. MingLiU) by the lengths and checksums of Type42-persistent subtables (`cvt ', `fpgm', and `prep') when a TrueType font without family name is given. The previous fix, introduced in 2.4.3, was too rigorous, causing many subsetted fonts (mainly from PDF files) displayed badly because FreeType forced rendering with the TrueType bytecode engine instead of the autohinter. - Better support for 64bit platforms. - More fixes to improve handling of broken fonts. ====================================================================== CHANGES BETWEEN 2.4.2 and 2.4.3 (2010-Oct-03) I. IMPORTANT BUG FIXES - Fix rendering of certain cubic, S-shaped arcs. This regression has been introduced in version 2.4.0. II. MISCELLANEOUS - To fix the above mentioned rendering issue, a new spline flattening algorithm has been introduced which speeds up both conic and cubic arcs. - Handling of broken fonts has been further improved. ====================================================================== CHANGES BETWEEN 2.4.1 and 2.4.2 (2010-Aug-06) I. IMPORTANT BUG FIXES - A stack overflow in CFF Type2 CharStrings interpreter is fixed. - Handling Type 42 font deallocation was broken; additionally, the library is now more robust against malformed Type 42 fonts. II. MISCELLANEOUS - Two new functions, `FT_Reference_Library' (in FT_MODULE_H) and `FT_Reference_Face' (in FT_FREETYPE_H), have been added to simplify life-cycle management. A counter gets initialized to 1 at the time an FT_Library (or FT_Face) structure is created. The two new functions increment the respective counter. `FT_Done_Library' and `FT_Done_Face' then only destroy a library or face if the counter is 1, otherwise they simply decrement the counter. ====================================================================== CHANGES BETWEEN 2.4.0 and 2.4.1 (2010-Jul-18) I. IMPORTANT CHANGES - A serious bug in the CFF font module prevented display of many glyphs in CFF fonts like `MinionPro-Regular.otf'. ====================================================================== CHANGES BETWEEN 2.3.12 and 2.4.0 (2010-Jul-12) I. IMPORTANT CHANGES - Since May 2010, all patents regarding the TrueType bytecode interpreter have expired worldwide. Consequently, we now define TT_CONFIG_OPTION_BYTECODE_INTERPRETER by default (and undefine TT_CONFIG_OPTION_UNPATENTED_HINTING). - A new function `FT_Library_SetLcdFilterWeights' is available to adjust the filter weights set by `FT_Library_SetLcdFilter'. II. MISCELLANEOUS - Thanks to many reports from Robert Święcki, FreeType's stability in handling broken or damaged fonts is much improved. - Support for LCD filter control has been added to the demo programs `ftdiff' and `ftview'. ====================================================================== CHANGES BETWEEN 2.3.11 and 2.3.12 I. IMPORTANT CHANGES - For `FT_Open_Face', new parameters are available to ignore preferred family names: FT_PARAM_TAG_IGNORE_PREFERRED_FAMILY and FT_PARAM_TAG_IGNORE_PREFERRED_SUBFAMILY. II. MISCELLANEOUS - Support for incremental font loading (controlled with the FT_CONFIG_OPTION_INCREMENTAL macro) is now active by default. - Better support for vertical metrics. - Various minor bug fixes. ====================================================================== CHANGES BETWEEN 2.3.10 and 2.3.11 I. IMPORTANT BUG FIXES - Version 2.3.10 broke PCF support. ====================================================================== CHANGES BETWEEN 2.3.10 and 2.3.9 I. IMPORTANT BUG FIXES - If all ASCII digits in a font have the same (unscaled) width, the autohinter respects this and won't change it. - TrueType fonts are now rasterized correctly if the horizontal and vertical resolution differ. - Type 1 fonts are now handled with increased precision internally to avoid serious rounding issues if non-integral coordinates are encountered. - Horizontally condensed CFF fonts (using the font matrix) were rendered incorrectly. This bug has been introduced after release 2.3.5. II. IMPORTANT CHANGES - Support for the SFNT cmap 13 table format (as defined by the new OpenType 1.6 specification) has been added. - B/W rasterization of well-hinted TrueType fonts at small sizes has been greatly improved. - Calculation of vertical metrics in OpenType fonts has been improved. III. MISCELLANEOUS - It is now possible to change the emboldening factor in the `ftview' demo program with keys `e' and `E'. - It is now possible to change the slant value in the `ftview' demo program with keys `s' and `S'. - The 5-levels grayscale mode of the `ftraster' module (which FreeType doesn't use by default) was broken since version 2.3.0. - Compilation of the `ftgrays' and `ftraster' modules was broken in stand-alone mode. - Various fixes for compilation on 64bit and 16bit architectures. ====================================================================== CHANGES BETWEEN 2.3.9 and 2.3.8 I. IMPORTANT BUG FIXES - Very unfortunately, FreeType 2.3.8 contained a change that broke its official ABI. The end result is that programs compiled against previous versions of the library, but dynamically linked to 2.3.8 can experience memory corruption if they call the `FT_Get_PS_Font_Info' function. We recommend all users to upgrade to 2.3.9 as soon as possible, or to downgrade to a previous release of the library if this is not an option. The origin of the bug is that a new field was added to the publicly defined `PS_FontInfoRec' structure. Unfortunately, objects of this type can be stack or heap allocated by callers of `FT_Get_PS_Font_Info', resulting in a memory buffer overwrite with its implementation in 2.3.8. If you want to know whether your code is vulnerable to this issue, simply search for the substrings `PS_FontInfo' and `PS_Font_Info' in your source code. If none is found, your code is safe and is not affected. The FreeType team apologizes for the problem. - The POSIX support of MacOS resource-fork fonts (Suitcase fonts and LaserWriter Type1 PostScript fonts) was broken in 2.3.8. If FreeType2 is built without Carbon framework, these fonts are not handled correctly. Version 2.3.7 didn't have this bug. - `FT_Get_Advance' (and `FT_Get_Advances') returned bad values for almost all font formats except TrueType fonts. - Fix a bug in the SFNT kerning table loader/parser which could crash the engine if certain malformed tables were encountered. - Composite SFNT bitmaps are now handled correctly. II. IMPORTANT CHANGES - The new functions `FT_Get_CID_Is_Internally_CID_keyed' and `FT_Get_CID_From_Glyph_Index' can be used to access CID-keyed CFF fonts via CID values. This code has been contributed by Michael Toftdal. III. MISCELLANEOUS - `FT_Outline_Get_InsideBorder' returns FT_STROKER_BORDER_RIGHT for empty outlines. This was incorrectly documented. - The `ftview' demo program now supports UTF-8 encoded strings. ====================================================================== CHANGES BETWEEN 2.3.8 and 2.3.7 I. IMPORTANT BUG FIXES - CID-keyed fonts in an SFNT wrapper were not handled correctly. - The smooth renderer produced truncated images (on the right) for outline parts with negative horizontal values. Most fonts don't contain outlines left to the y coordinate axis, but the effect was very noticeable for outlines processed with FT_Glyph_Stroke, using thick strokes. - `FT_Get_TrueType_Engine_Type' returned a wrong value if both configuration macros TT_CONFIG_OPTION_BYTECODE_INTERPRETER and TT_CONFIG_OPTION_UNPATENTED_HINTING were defined. - The `face_index' field in the `FT_Face' structure wasn't initialized properly after calling FT_Open_Face and friends with a positive face index for CFFs, WinFNTs, and, most importantly, for TrueType Collections (TTCs). II. IMPORTANT CHANGES - Rudimentary support for Type 1 fonts and CID-keyed Type 1 fonts in an SFNT wrapper has been added -- such fonts are used on the Mac. The core SFNT tables `TYP1' and `CID ' are passed to the PS Type 1 and CID-keyed PS font drivers; other tables (`ALMX', `BBOX', etc.) are not supported yet. - A new interface to extract advance values of glyphs without loading their outlines has been added. The functions are called `FT_Get_Advance' and `FT_Get_Advances'; they are defined in file `ftadvanc.h' (to be accessed as FT_ADVANCES_H). - A new function `FT_Get_FSType_Flags' (in FT_FREETYPE_H) has been contributed by David Bevan to access the embedding and subsetting restriction information of fonts. III. MISCELLANEOUS - FT_MulFix is now an inlined function; by default, assembler code is provided for x86 and ARM. See FT_CONFIG_OPTION_INLINE_MULFIX and FT_CONFIG_OPTION_NO_ASSEMBLER (in ftoption.h) for more. - The handling of `tricky' fonts (this is, fonts which don't work with the autohinter, needing the font format's hinting engine) has been generalized and changed slightly: . A new face flag FT_FACE_FLAG_TRICKY indicates that the font format's hinting engine is necessary for correct rendering. The macro FT_IS_TRICKY can be used to check this flag. . FT_LOAD_NO_HINTING is now ignored for tricky fonts. To really force raw loading of such fonts (without hinting), both FT_LOAD_NO_HINTING and FT_LOAD_NO_AUTOHINT must be used -- this is something which you probably never want to do. . Tricky TrueType fonts always use the bytecode interpreter, either the patented or unpatented version. - The function `FT_GlyphSlot_Own_Bitmap' has been moved from FT_SYNTHESIS_H to FT_BITMAP_H; it is now part of the `official' API. (The functions in FT_SYNTHESIS_H are still subject to change, however.) - In the `ftdiff' demo program you can now toggle the use of FT_LOAD_IGNORE_GLOBAL_ADVANCE_WIDTH with key `a'. ====================================================================== CHANGES BETWEEN 2.3.7 and 2.3.6 I. IMPORTANT BUG FIXES - If the library was compiled on an i386 platform using gcc, and compiler option -O3 was given, `FT_MulFix' sometimes returned incorrect results which could have caused problems with `FT_Request_Metrics' and `FT_Select_Metrics', returning an incorrect descender size. - Pure CFFs without subfonts were scaled incorrectly if the font matrix was non-standard. This bug has been introduced in version 2.3.6. - The `style_name' field in the `FT_FaceRec' structure often contained a wrong value for Type 1 fonts. This misbehaviour has been introduced in version 2.3.6 while trying to fix another problem. [Note, however, that this value is informative only since the used algorithm to extract it is very simplistic.] II. IMPORTANT CHANGES - Two new macros, FT_OUTLINE_SMART_DROPOUTS and FT_OUTLINE_EXCLUDE_STUBS, have been introduced. Together with FT_OUTLINE_IGNORE_DROPOUTS (which was ignored previously) it is now possible to control the dropout mode of the `raster' module (for B&W rasterization), using the `flags' field in the `FT_Outline' structure. - The TrueType bytecode interpreter now passes the dropout mode to the B&W rasterizer. This greatly increases the output for small ppem values of many fonts like `pala.ttf'. ====================================================================== CHANGES BETWEEN 2.3.6 and 2.3.5 I. IMPORTANT BUG FIXES - A bunch of potential security problems have been found. All users should update. - Microsoft Unicode cmaps in TrueType fonts are now always preferred over Apple cmaps. This is not a bug per se, but there exist some buggy fonts created for MS which have broken Apple cmaps. This affects only the automatic selection of FreeType; it's always possible to manually select an Apple Unicode cmap if desired. - Many bug fixes to the TrueType bytecode interpreter. - Improved Mac support. - Subsetted CID-keyed CFFs are now supported correctly. - CID-keyed CFFs with subfonts which are scaled in a non-standard way are now handled correctly. - A call to FT_Open_Face with `face_index' < 0 crashed FreeType if the font was a Windows (bitmap) FNT/FON. II. IMPORTANT CHANGES - The new function `FT_Get_CID_Registry_Ordering_Supplement' gives access to those fields in a CID-keyed font. The code has been contributed by Derek Clegg. - George Williams contributed code to validate the new `MATH' OpenType table (within the `otvalid' module). The `ftvalid' demo program has been extended accordingly. - An API for cmap 14 support (for Unicode Variant Selectors, UVS) has been contributed by George Williams. - A new face flag FT_FACE_FLAG_CID_KEYED has been added, together with a macro FT_IS_CID_KEYED which evaluates to 1 if the font is CID-keyed. III. MISCELLANEOUS - Build support for symbian has been contributed. - Better WGL4 glyph name support, contributed by Sergey Tolstov. - Debugging output of the various FT_TRACEX macros is now sent to stderr. - The `ftview' demo program now provides artificial slanting too. - The `ftvalid' demo program has a new option `-f' to select the font index. ====================================================================== CHANGES BETWEEN 2.3.5 and 2.3.4 I. IMPORTANT BUG FIXES - Some subglyphs in TrueType fonts were handled incorrectly due to a missing graphics state reinitialization. - Large .Z files (as distributed with some X11 packages) weren't handled correctly, making FreeType increase the heap stack in an endless loop. - A large number of bugs have been fixed to avoid crashes and endless loops with invalid fonts. II. IMPORTANT CHANGES - The two new cache functions `FTC_ImageCache_LookupScaler' and `FTC_SBit_Cache_LookupScaler' have been added to allow lookup of glyphs using an `FTC_Scaler' object; this makes it possible to use fractional pixel sizes in the cache. The demo programs have been updated accordingly to use this feature. - A new API `FT_Get_CMap_Format' has been added to get the cmap format of a TrueType font. This is useful in handling PDF files. The code has been contributed by Derek Clegg. - The auto-hinter now produces better output by default for non-Latin scripts like Indic. This was done by using the CJK hinting module as the default instead of the Latin one. Thanks to Rahul Bhalerao for this suggestion. - A new API `FT_Face_CheckTrueTypePatents' has been added to find out whether a given TrueType font uses patented bytecode instructions. The `ft2demos' bundle contains a new program called `ftpatchk' which demonstrates its usage. - A new API `FT_Face_SetUnpatentedHinting' has been added to enable or disable the unpatented hinter. - Support for Windows FON files in PE format has been contributed by Dmitry Timoshkov. III. MISCELLANEOUS - Vincent Richomme contributed Visual C++ project files for Pocket PCs. ====================================================================== CHANGES BETWEEN 2.3.4 and 2.3.3 I. IMPORTANT BUG FIXES - A serious bug in the handling of bitmap fonts (and bitmap strikes of outline fonts) has been introduced in 2.3.3. ====================================================================== CHANGES BETWEEN 2.3.3 and 2.3.2 I. IMPORTANT BUG FIXES - Remove a serious regression in the TrueType bytecode interpreter that was introduced in version 2.3.2. Note that this does not disable the improvements introduced to the interpreter in version 2.3.2, only some ill cases that occurred with certain fonts (though a few popular ones). - The auto-hinter now ignores single-point contours for computing blue zones. This bug created `wavy' baselines when rendering text with various fonts that use these contours to model mark-attach points (these are points that are never rasterized and are placed outside of the glyph's real outline). - The `rsb_delta' and `lsb_delta' glyph slot fields are now set to zero for mono-spaced fonts. Otherwise code that uses them would essentially ruin the fixed-advance property. - Fix CVE-2007-1351 which can cause an integer overflow while parsing BDF fonts, leading to a potentially exploitable heap overflow condition. II. MISCELLANEOUS - Fixed compilation issues on some 64-bit platforms (see ChangeLog for details). - A new demo program `ftdiff' has been added to compare TrueType hinting, FreeType's auto hinting, and rendering without hinting in three columns. ====================================================================== CHANGES BETWEEN 2.3.2 and 2.3.1 I. IMPORTANT BUG FIXES - FreeType returned incorrect kerning information from TrueType fonts when the bytecode interpreter was enabled. This happened due to a typo introduced in version 2.3.0. - Negative kerning values from PFM files are now reported correctly (they were read as 16-bit unsigned values from the file). - Fixed a small memory leak when `FT_Init_FreeType' failed for some reason. - The Postscript hinter placed and sized very thin and ghost stems incorrectly. - The TrueType bytecode interpreter has been fixed to get rid of most of the rare differences seen in comparison to the Windows font loader. II. IMPORTANT CHANGES - The auto-hinter now better deals with serifs and corner cases (e.g., glyph '9' in Arial at 9pt, 96dpi). It also improves spacing adjustments and doesn't change widths for non-spacing glyphs. - Many Mac-specific functions are deprecated (but still available); modern replacements have been provided for them. See the documentation in file `ftmac.h'. ====================================================================== CHANGES BETWEEN 2.3.1 and 2.3.0 I. IMPORTANT BUG FIXES - The TrueType interpreter sometimes returned incorrect horizontal metrics due to a bug in the handling of the SHZ instruction. - A typo in a security check introduced after version 2.2.1 prevented FreeType to render some glyphs in CFF fonts. ====================================================================== CHANGES BETWEEN 2.3.0 and 2.2.1 I. IMPORTANT BUG FIXES - The PCF font loader is now much more robust while loading malformed font files. - Various memory leaks have been found and fixed. - The TrueType name loader now deals properly with some fonts that encode their names in UTF-16 (the specification was vague, and the code incorrectly assumed UCS-4). - Fixed the TrueType bytecode loader to deal properly with subtle monochrome/gray issues when scaling the CVT. Some fonts exhibited bad rendering artifacts otherwise. - `FT_GlyphSlot_Embolden' now supports vertical layouts correctly (it mangled the vertical advance height). - Fixed byte endian issues of `ftmac.c' to support Mac OS X on i386. - The PFR font loader no longer erroneously tags font files without any outlines as FT_FACE_FLAG_SCALABLE. II. NEW API FUNCTIONS - `FT_Library_SetLcdFilter' allows you to select a special filter to be applied to the bitmaps generated by `FT_Render_Glyph' if one of the FT_RENDER_MODE_LCD and FT_RENDER_MODE_LCD_V modes has been selected. This filter is used to reduce color fringes; several settings are available through the FT_LCD_FILTER_XXX enumeration. Its declaration and documentation can be found in file `include/freetype/ftlcdfil.h' (to be accessed with macro FT_LCD_FILTER_H). *IMPORTANT*: This function returns an error (FT_Err_Unimplemented_Feature) in default builds of the library for patent reasons. See below. - `FT_Get_Gasp' allows you to query the flags of the TrueType `gasp' table for a given character pixel size. This is useful to duplicate the text rendering of MS Windows when the native bytecode interpreter is enabled (which isn't the default for other patent reasons). Its declaration and documentation can be found in file `include/freetype/ftgasp.h' (to be accessed with macro FT_GASP_H). III. IMPORTANT CHANGES - The auto-hinter has been tuned a lot to improve its results with serif fonts, resulting in much better font rendering of many web pages. - The unpatented hinter is now part of the default build of the library; we have added code to automatically support `tricky' fonts that need it. This means that FreeType should `just work' with certain Asian fonts, like MingLiU, which cannot properly be loaded without a bytecode interpreter, but which fortunately do not use any of the patented bytecode opcodes. We detect these fonts by name, so please report any font file that doesn't seem to work with FreeType, and we shall do what we can to support it in a next release. Note that the API hasn't changed, so you can still force unpatented hinting with a special parameter to `FT_Open_Face' as well. This might be useful in same cases; for example, a PDF reader might present a user option to activate it to deal with certain `tricky' embedded fonts which cannot be clearly identified. If you are a developer for embedded systems, you might want to *disable* the feature to save code space by undefining TT_CONFIG_OPTION_UNPATENTED_HINTING in file `ftoption.h'. - LCD-optimized rendering is now *disabled* in all default builds of the library, mainly due to patent issues. For more information see: https://lists.gnu.org/archive/html/freetype/2006-09/msg00064.html A new configuration macro FT_CONFIG_OPTION_SUBPIXEL_RENDERING has been introduced in `ftoption.h'; manually define it in this file if you want to re-enable the feature. The change only affects the implementation, not the FreeType API. This means that clients don't need to be modified, because the library still generates LCD decimated bitmaps, but with the added constraint that R=G=B on each triplet. The displayed result should be equal to normal anti-aliased rendering. Additionally, if FT_CONFIG_OPTION_SUBPIXEL_RENDERING is not defined, the new `FT_Library_SetLcdFilter' function returns the FT_Err_Unimplemented_Feature error code. - Some computation bugs in the TrueType bytecode interpreter were found, which allow us to get rid of very subtle and rare differences we had experienced with the Windows renderer. - It is now possible to cross-compile the library easily. See the file `docs/INSTALL.CROSS' for details. - The file `src/base/ftmac.c' now contains code for Mac OS X only; its deprecated function `FT_GetFile_From_Mac_Font_Name' always returns an error even if the QuickDraw framework is available. The previous version has been moved to `builds/mac/ftmac.c'. Selecting configure option `--with-quickdraw-carbon' makes the build process use the original `ftmac.c' file instead of the Mac OS X-only version. IV. MISCELLANEOUS - Various performance and memory footprint optimizations have been performed on the TrueType and CFF font loaders, sometimes with very drastic benefits (e.g., the TrueType loader is now about 25% faster; FreeType should use less heap memory under nearly all conditions). - The anti-aliased rasterizer has been optimized and is now 15% to 25% percent faster than in previous versions, depending on content. - The Type 1 loader has been improved; as an example, it now skips top-level dictionaries properly. - Better support for Mac fonts on POSIX systems, plus compilation fixes for Mac OS X on ppc64 where `ftmac.c' cannot be built. - Configuration without `--with-old-mac-fonts' does not include `ftmac.c' (this was the behaviour in FreeType version 2.1.10). - The TrueTypeGX validator (gxvalid) checks the order of glyph IDs in the kern table. ====================================================================== CHANGES BETWEEN 2.2.1 and 2.2 I. IMPORTANT BUG FIXES - Various integer overflows have been fixed. - PFB fonts with MacOS resource fork weren't handled correctly on non-MacOS platforms. ====================================================================== CHANGES BETWEEN 2.2 and 2.1.10 (not released officially) I. IMPORTANT BUG FIXES - Vertical metrics for SFNT fonts were incorrect sometimes. - The FT_HAS_KERNING macro always returned 0. - CFF OpenType fonts didn't return correct vertical metrics for glyphs with outlines. - If FreeType was compiled without hinters, all font formats based on PS outlines weren't scaled correctly. II. IMPORTANT CHANGES - Version 2.2 no longer exposes its internals, this is, the header files located in the `include/freetype/internal' directory of the source package are not copied anymore by the `make install' command. Consequently, a number of rogue clients which directly access FreeType's internal functions and structures won't compile without modification. We provide patches for most of those rogue clients. See the following page for more information: https://www.freetype.org/freetype2/patches/rogue-patches.html Note that, as a convenience to our Unix desktop users, version 2.2 is *binary* compatible with FreeType 2.1.7, which means that installing this release on an existing distribution shall not break any working desktop. - FreeType's build mechanism has been redesigned. With GNU make it is now sufficient in most cases to edit two files: `modules.cfg', to select the library components, and the configuration file `include/freetype/config/ftoption.h' (which can be copied to the objects directory). Removing unused module directories to prevent its compilation and editing `include/freetype/config/ftmodule.h' is no longer necessary. - The LIGHT hinting algorithm produces more pleasant results. Also, using the FT_LOAD_TARGET_LIGHT flags within FT_Load_Glyph always forces auto-hinting, as a special exception. This allows you to experiment with it even if you have enabled the TrueType bytecode interpreter in your build. - The auto hinter now employs a new algorithm for CJK fonts, based on Akito Hirai's patch. Note that this only works for fonts with a Unicode charmap at the moment. - The following callback function types have changed slightly (by adding the `const' keyword where appropriate): FT_Outline_MoveToFunc FT_Outline_LineToFunc FT_Outline_ConicToFunc FT_Outline_CubicToFunc FT_SpanFunc FT_Raster_RenderFunc FT_Glyph_TransformFunc FT_Renderer_RenderFunc FT_Renderer_TransformFunc Note that this doesn't affect binary backward compatibility. - On MacOS, new APIs have been added as replacements for legacy APIs: `FT_New_Face_From_FSRef' for `FT_New_Face_From_FSSpec', and `FT_GetFile_From_Mac_ATS_Name' for `FT_GetFile_From_Mac_Name'. Legacy APIs are still available, if FreeType is built without disabling them. - A new API `FT_Select_Size' has been added to select a bitmap strike by its index. Code using other functions to select bitmap strikes should be updated to use this function. - A new API `FT_Get_SubGlyph_Info' has been added to retrieve subglyph data. This can be used by rogue clients which used to access the internal headers to get the corresponding data. - In 2.1.10, the behaviour of `FT_Set_Pixel_Sizes' was changed for BDF/PCF fonts, and only for them. This causes inconsistency. In this release, we undo the change. The intent of the change in 2.1.10 is to allow size selection through real dimensions, which can now be done through `FT_Request_Size'. - Some security issues were discovered and fixed in the CFF and Type 1 loader, causing crashes of FreeType by malformed font files. III. MISCELLANEOUS - The documentation for FT_LOAD_TARGET_XXX and FT_RENDER_MODE_XXX values now better reflects its usage and differences: One set is used to specify the hinting algorithm, the other to specify the pixel rendering mode. - `FT_New_Face' and `FT_New_Face_From_FSSpec' in ftmac.c have been changed to count supported scalable faces (sfnt, LWFN) only, and to return the number of available faces via face->num_faces. Unsupported bitmap faces (fbit, NFNT) are ignored. - builds/unix/configure has been improved for MacOS X. It now automatically checks available functions in Carbon library, and prepare to use newest functions by default. Options to specify the dependencies of each Carbon APIs (FSSpec, FSRef, old/new QuickDraw, ATS) are available too. By manual disabling of all QuickDraw functionality, FreeType can be built without `deprecated function' warnings on MacOS 10.4.x, but FT_GetFile_Mac_Name in ftmac.c then is changed to a dummy function, and returns an `unimplemented' error. For details see builds/mac/README. - SFNT cmap handling has been improved, mainly to run much faster with CJK fonts. - A new function `FT_Get_TrueType_Engine_Type (declared in `FT_MODULE_H') is provided to determine the status of the TrueType bytecode interpreter compiled into the library (patented, unpatented, unimplemented). - Vertical metrics of glyphs are synthesized if the font does not provide such information. You can tell whether the metrics are synthesized or not by checking the FT_FACE_FLAG_VERTICAL flag of the face. - The demo programs `ftview' and `ftstring' have been rewritten for better readability. `ftview' has a new switch `-p' to test FT_New_Memory_Face (instead of FT_New_Face). - FreeType now honours bit 1 in the `head' table of TrueType fonts (meaning `left sidebearing point at x=0'). This helps with some buggy fonts. - Rudimentary support for Adobe's new `SING Glyphlet' format. See https://www.adobe.com/content/dam/acom/en/devnet/font/pdfs/5148.SING_Tutorial.pdf for more information. - The `ftdump' program from the `ft2demos' bundle now shows some information about charmaps. It also supports a new switch `-v' to increase verbosity. - Better AFM support. This includes track kerning support. ====================================================================== CHANGES BETWEEN 2.1.10 and 2.1.9 I. IMPORTANT BUG FIXES - The size comparison for BDF and PCF files could fail sometimes. - Some CFF files were still not loaded correctly. Patch from Derek Noonburg. - The stroker still had some serious bugs. - Boris Letocha fixed a bug in the TrueType interpreter: The NPUSHW instruction wasn't skipped correctly in IF clauses. Some fonts like `Helvetica 75 Bold' failed. - Another serious bug in handling TrueType hints caused many distortions. It has been introduced in version 2.1.8, and it is highly recommended to upgrade. - FreeType didn't properly parse empty Type 1 glyphs. - An unbound dynamic buffer growth was fixed in the PFR loader. - Several bugs have been fixed in the cache sub-system. - FreeType behaved incorrectly when resizing two distinct but very close character pixel sizes through `FT_Set_Char_Size' (Savannah bug #12263). - The auto-hinter didn't work properly for fonts without a Unicode charmap -- it even refused to load the glyphs. II. IMPORTANT CHANGES - Many fixes have been applied to drastically reduce the amount of heap memory used by FreeType, especially when using memory-mapped font files (which is the default on Unix systems which support them). - The auto-hinter has been replaced with a new module, called the `auto-fitter'. It consumes less memory than its predecessor, and it is prepared to support non-latin scripts better in next releases. - George Williams contributed code to read kerning data from PFM files. - FreeType now uses the TT_NAME_ID_PREFERRED_FAMILY and TT_NAME_ID_PREFERRED_SUBFAMILY strings (if available) for setting family and style in SFNT fonts (patch from Kornfeld Eliyahu Peter). - A new API `FT_Sfnt_Table_Info' (in FT_TRUETYPE_TABLES_H) has been added to retrieve name and size information of SFNT tables. - A new API `FT_OpenType_Validate' (in FT_OPENTYPE_VALIDATE_H) has been added to validate OpenType tables (BASE, GDEF, GPOS, GSUB, JSTF). After validation it is no longer necessary to check for errors in those tables while accessing them. Note that this module might be moved to another library in the future to avoid a tight dependency between FreeType and the OpenType specification. - A new API in FT_BITMAP_H (`FT_Bitmap_New', `FT_Bitmap_Convert', `FT_Bitmap_Copy', `FT_Bitmap_Embolden', `FT_Bitmap_Done') has been added. Its use is to convert an FT_Bitmap structure in 1bpp, 2bpp, 4bpp, or 8bpp format into another 8bpp FT_Bitmap, probably using a different pitch, and to further manipulate it. - A new API `FT_Outline_Embolden' (in FT_OUTLINE_H) gives finer control how outlines are emboldened. - `FT_GlyphSlot_Embolden' (in FT_SYNTHESIS_H) now handles bitmaps also (code contributed by Chia I Wu). Note that this function is still experimental and may be replaced with a better API. - The method how BDF and PCF bitmap fonts are accessed has been refined. Formerly, FT_Set_Pixel_Sizes and FT_Set_Char_Size were synonyms in FreeType's BDF and PCF interface. This has changed now. FT_Set_Pixel_Sizes should be used to select the actual font dimensions (the `strike', which is the sum of the `FONT_ASCENT' and `FONT_DESCENT' properties), while FT_Set_Char_Size selects the `nominal' size (the `PIXELSIZE' property). In both functions, the width parameter is ignored. III. MISCELLANEOUS - The BDF driver no longer converts all returned bitmaps with a depth of 2bpp or 4bpp to a depth of 8bpp. The documentation has not mentioned this explicitly, but implementors might have relied on this after looking into the source files. - A new option `--ftversion' has been added to freetype-config to return the FreeType version. - The memory debugger has been updated to dump allocation statistics on all allocation sources in the library. This is useful to spot greedy allocations when loading and processing fonts. - We removed a huge array of constant pointers to constant strings in the `psnames' module. The problem was that compilations in PIC mode (i.e., when generating a Unix shared object/dll) put the array into the non-shared writable section of the library since absolute pointers are not relocatable by nature. This reduces the memory consumption by approximately 16KByte per process linked to FreeType. We now also store the array in a compressed form (as a trie) which saves about 20KByte of code as well. - Kirill Smelkov provided patches to make src/raster/ftraster.c compile stand-alone again. ====================================================================== CHANGES BETWEEN 2.1.9 and 2.1.8 I. IMPORTANT BUG FIXES - The function `FT_Get_CharMap_Index' was only declared, without any real code. For consistency, it has been renamed to `FT_Get_Charmap_Index'. (This function is needed to implement cmap caches.) - `FT_Outline_Get_BBox' sometimes returned incorrect values for conic outlines (e.g., for TrueType fonts). - Handling of `bhed' table has been fixed. - The TrueType driver with enabled byte code interpreter sometimes returned artifacts due to incorrect rounding. This bug has been introduced after version 2.1.4. - The BDF driver dropped the last glyph in the font. - The BDF driver now uses the DEFAULT_CHAR property (if available) to select a glyph shape for the undefined glyph. - The stroker failed for closed outlines and single points. II. IMPORTANT CHANGES - George Williams contributed code to handle Apple's font distortion technology found in GX fonts (`avar', `cvar', `fvar', and `gvar' tables; the Multiple Masters API has been slightly extended to cope with the new functionality). - The `FT_GlyphSlotRec' structure has been extended: The elements `lsb_delta' and `rsb_delta' give the difference between hinted and unhinted left and right side bearings if autohinting is active. Using those values can improve the inter-letter spacing considerably. See the documentation of `FT_GlyphSlotRec' and the `ftstring' demo program how to use it. - Loading TrueType and Type 1 fonts has been made much faster. - The stroker is no longer experimental (but the cache subsystem still is). III. MISCELLANEOUS - A new documentation file `formats.txt' describes various font formats supported (and not supported) by FreeType. ====================================================================== CHANGES BETWEEN 2.1.8 and 2.1.7 I. IMPORTANT BUG FIXES - The native TrueType hinter contained some bugs which prevented some fonts to be rendered correctly, most notably Legendum.otf. - The PostScript hinter now produces improved results. - The linear advance width and height values were incorrectly rounded, making them virtually unusable if not loaded with FT_LOAD_LINEAR_DESIGN. - Indexing CID-keyed CFF fonts is now working: The glyph index is correctly treated as a CID, similar to FreeType's CID driver module. Note that CID CMap support is still missing. - The FT_FACE_FLAG_GLYPH_NAMES flag is now set correctly for all font formats. - Some subsetted Type 1 fonts weren't parsed correctly. This bug has been introduced in 2.1.7. In summary, the Type 1 parser has become more robust. - Non-decimal numbers weren't parsed correctly in PS fonts. - The WinFNT driver now correctly reports FT_ENCODING_NONE for all but one encoding. Use the new FT_WinFNT_ID_XXX values together with `FT_Get_WinFNT_Header' to get the WinFNT charset ID. - The descender metrics (face->size->metrics.descender) for WinFNT bitmap fonts had the wrong sign. - The (emulated) `seac' support for CFF fonts was broken. - The `flex' operator didn't work for CFF fonts. - PS glyphs which use the `hintmask' operator haven't been rendered correctly in some cases. - Metrics for BDF and PCF bitmap font formats have been fixed. - Autohinting is now disabled for glyphs which are vertically distorted or mirrored (using a transformation matrix). This fixes a bug which produced zero-height glyphs. - The `freetype-config' script now handles --prefix and --exec-prefix correctly; it also returns the proper --rpath (or -R) value if FreeType has been built as a shared library. II. IMPORTANT CHANGES - Both PCF and BDF drivers now handle the SETWIDTH_NAME and ADD_STYLE_NAME properties. Values are appended to face->style_name; example: `Bold SemiCondensed'. - The PCF driver now handles bitmap fonts compressed with the LZW algorithm (extension .pcf.Z, compressed with `compress'). - A new API function `FT_Get_CMap_Language_ID' (declared in `tttables.h') is available to get the language ID of a TrueType/SFNT cmap. - The hexadecimal format of data after the `StartData' command in CID-keyed Type 1 fonts is now supported. While this can't occur in file-based fonts, it can happen in document-embedded resources of PostScript documents. - Embedded bitmaps in SFNT-based CFF fonts are now supported. - A simple API is now available to control FreeType's tracing mechanism if compiled with FT_DEBUG_LEVEL_TRACE. See the file `ftdebug.h' for more details. - YAMATO Masatake contributed improved handling of MacOS resource forks on non-MacOS platforms (for example, Linux can mount MacOS file systems). - Support for MacOS has been improved; there is now a new function `FT_New_Face_From_FSSpec' similar to `FT_New_Face' except that it accepts an FSSpec instead of a path. - The cache sub-system has been rewritten. - There is now support for deinstallation of faces. - A new API function `FTC_Manager_RemoveFaceID' has been added to delete all `idle' nodes that correspond to a given FTC_FaceID. All `locked' nodes (i.e., those with a reference count > 0), will be modified to prevent them from appearing in further lookups (they will be cleaned normally when their reference count reaches 0). - There is now support for point scaling (i.e., providing character sizes in points + dpis, instead of pixels). - Three abstract cache classes are now available: FTC_GCache: Used to store one glyph item per cache node, with the ability to group common attributes into `families'. This replaces the old FTC_GlyphCache class. FTC_ICache: Used to store one FT_Glyph per cache node. This extends FTC_GCache. Family definition, family comparison, and glyph loading are however left to sub-classes. FTC_SCache: Used to store up to 16 small bitmaps per cache node. This extends FTC_GCache. Family definition, family comparison and glyph loading are however left to sub-classes. - The file `src/cache/ftcbasic.c' implements: FTC_ImageCache: Extends FTC_ICache; implements family definitions and glyph loading similar to the old API. FTC_SBitCache: Extends FTC_SCache, implements family definitions and glyph loading similar to the old API Client applications should be able to extend FTC_GCache, FTC_ICache, or FTC_SCache much more easily (i.e., less code to write, and less callbacks). For example, one could envision caches that are capable of storing transformed (obliqued), stroked, emboldened, or colored glyph images. Use `ftcbasic.c' as an example. - All public APIs are now in `include/freetype/ftcache.h', (to be accessed as `FT_CACHE_H'). The contents of `include/freetype/cache/' is only needed by applications that wish to implement their own caches. - There were some major performance improvements through the use of various programming tricks. Cache hits are up to 70% faster than in the old code. - The FTC_CMapCache has been simplified. Charmaps can only be accessed by index right now. There is also a new API named `FT_Charmap_GetIndex' for this purpose. - The demo programs have been updated to the new code. The previous versions will not work with the current one. - Using an invalid face index in FT_Open_Face and friends now causes an error even if the font contains a single face only. III. MISCELLANEOUS - Wolfgang Domröse contributed support files for building FreeType on the Atari using the PureC compiler. Note that the Atari is a 16bit platform. - Vitaliy Pasternak contributed project files for VS.NET 2003. ====================================================================== CHANGES BETWEEN 2.1.7 and 2.1.6 I. IMPORTANT BUG FIXES - Updated to newest libtool version, fixing build problems on various platforms. - On Unix platforms, `make install' didn't copy the correct `ftconfig.h' file. Note that version 2.1.7 contains the same library C source code as version 2.1.6. ====================================================================== CHANGES BETWEEN 2.1.6 and 2.1.5 I. IMPORTANT BUG FIXES - The PFR font driver didn't load kerning tables correctly, and the functions in FT_PFR_H didn't work at all. - Type 1 font files in binary format (PFB) with an end-of-file indicator weren't accepted by the FreeType engine. - Fonts which contain /PaintType and /StrokeWidth no longer cause a segfault. This bug has been introduced in version 2.1.5. - Fonts loaded with FT_LOAD_RENDER no longer cause strange results. This bug has been introduced in version 2.1.5. - Some Windows (bitmap) FNT/FON files couldn't be handled correctly. II. IMPORTANT CHANGES - The internal module API has been heavily changed in favor of massive simplifications within the font engine. This also means that authors of third-party modules must adapt their code to the new scheme. NOTE: THE NEW SCHEME IS NOT COMPLETED YET. PLEASE WAIT UNTIL A FINAL ANNOUNCEMENT! - The PostScript parser has been enhanced to handle comments and strings correctly. Additionally, more syntax forms are recognized. - Added the optional unpatented hinting system for TrueType. It allows typefaces which need hinting to produce correct glyph forms (e.g., Chinese typefaces from Dynalab) to work acceptably without infringing Apple patents. This system is compiled only if TT_CONFIG_OPTION_COMPILE_UNPATENTED_HINTING is defined in ftoption.h (activated by default). III. MISCELLANEOUS - There is now a guard in the public header files to protect against inclusion of freetype.h from FreeType 1. - Direct inclusion of freetype.h and other public header files no longer works. You have to use the documented scheme #include <ft2build.h> #include FT_FREETYPE_H to load freetype.h with a symbolic name. This protects against renaming of public header files (which shouldn't happen but actually has, avoiding two public header files with the same name). ====================================================================== CHANGES BETWEEN 2.1.5 and 2.1.4 I. IMPORTANT BUG FIXES - Parsing the /CIDFontName field now removes the leading slash to be in sync with other font drivers. - gzip support was buggy. Some fonts could not be read. - Fonts which have nested subglyphs more than one level deep no longer cause a segfault. - Creation of synthetic cmaps for fonts in CFF format was broken partially. - Numeric font dictionary entries for synthetic fonts are no longer overwritten. - The font matrix wasn't applied to the advance width for Type1, CID, and CFF fonts. This caused problems when loading certain synthetic Type 1 fonts like `Helvetica Narrow'. - The test for the charset registry in BDF and PCF fonts is now case-insensitive. - FT_Vector_Rotate sometimes returned strange values due to rounding errors. - The PCF driver now returns the correct number of glyphs (including an artificial `notdef' glyph at index 0). - FreeType now supports buggy CMaps which are contained in many CJK fonts from Dynalab. - Opening an invalid font on a Mac caused a segfault due to double-freeing memory. - BDF fonts with more than 32768 glyphs weren't supported properly. II. IMPORTANT CHANGES - Accessing bitmap font formats has been synchronized. To do that the FT_Bitmap_Size structure has been extended to contain new fields `size', `x_ppem', and `y_ppem'. - The FNT driver now returns multiple faces, not multiple strikes. - The `psnames' module has been updated to the Adobe Glyph List version 2.0. - The `psnames' module now understands `uXXXX[X[X]]' glyph names. - The algorithm for guessing the font style has been improved. - For fonts in SFNT format, root->height is no longer increased if the line gap is zero. There exist fonts (containing e.g. form drawing characters) which intentionally have a zero line gap value. - ft_glyph_bbox_xxx flags are now deprecated in favour of FT_GLYPH_BBOX_XXX. - ft_module_xxx flags are now deprecated in favour of FT_MODULE_XXX. - FT_ENCODING_MS_{SJIS,GB2312,BIG5,WANSUNG,JOHAB} are now deprecated in favour of FT_ENCODING_{SJIS,GB2312,BIG5,WANSUNG,JOHAB} -- those encodings are not specific to Microsoft. III. MISCELLANEOUS - The autohinter has been further improved; for example, `m' glyphs now retain its vertical symmetry. - Partial support of Mac fonts on non-Mac platforms. - `make refdoc' (after first `make') builds the HTML documentation. You need Python for this. - The make build system should now work more reliably on DOS-like platforms. - Support for EMX gcc and Watson C/C++ compilers on MS-DOS has been added. - Better VMS build support. - Support for the pkg-config package by providing a `freetype.pc' file. - New configure option --with-old-mac-fonts for Darwin. - Some source files have been renamed (mainly to fit into the 8.3 naming scheme). ====================================================================== CHANGES BETWEEN 2.1.4 and 2.1.3 I. IMPORTANT BUG FIXES - Updated to newest libtool version, fixing build problems on various platforms. - A fix in the Gzip stream reader: It couldn't read certain .gz files properly due to a small typo. In certain cases, FreeType could also loop endlessly when trying to load tiny gzipped files. - The configure script now tries to use the system-wide zlib when it finds one (instead of the copy found in src/gzip). And `freetype-config' has been updated to return relevant flags in this case when invoked with `--libs' (e.g. `-lzlib'). - Certain fonts couldn't be loaded by 2.1.3 because they lacked a Unicode charmap (e.g. SYMBOL.TTF). FreeType erroneously rejected them. - The CFF loader was modified to accept fonts which only contain a subset of their reference charset. This prevented the correct use of PDF-embedded fonts. - The logic to detect Unicode charmaps has been modified. This is required to support fonts which include both 16-bit and 32-bit charmaps (like very recent asian ones) using the new 10 and 12 SFNT formats. - The TrueType loader now limits the depth of composite glyphs. This is necessary to prevent broken fonts to break the engine by blowing the stack with recursive glyph definitions. - The CMap cache is now capable of managing UCS-4 character codes that are mapped through extended charmaps in recent TrueType/OpenType fonts. - The cache sub-system now properly manages out-of-memory conditions instead of blindly reporting them to the caller. This means that it will try to empty the cache before restarting its allocations to see if that can help. - The PFR driver didn't return the list of available embedded bitmaps properly. - There was a nasty memory leak when using embedded bitmaps in certain font formats. II. IMPORTANT CHANGES - David Chester contributed some enhancements to the auto-hinter that significantly increase the quality of its output. The Postscript hinter was also improved in several ways. - The FT_RENDER_MODE_LIGHT render mode was implemented. - A new API function called `FT_Get_BDF_Property' has been added to FT_BDF_H to retrieve BDF properties from BDF _and_ PCF font files. THIS IS STILL EXPERIMENTAL, since it hasn't been properly tested yet. - A Windows FNT specific API has been added, mostly to access font headers. This is used by Wine. - TrueType tables without an `hmtx' table are now tolerated when an incremental interface is used. This happens for certain Type42 fonts passed from Ghostscript to FreeType. - The PFR font driver is now capable of returning the font family and style names when they are available (instead of the sole `FontID'). This is performed by parsing an *undocumented* portion of the font file! III. MISCELLANEOUS - The path stroker in FT_STROKER_H has entered beta stage. It now works very well, but its interface might change a bit in the future. More on this in later releases. - The documentation for FT_Size_Metrics didn't appear properly in the API reference. - The file docs/VERSION.DLL has been updated to explain versioning with FreeType (i.e., comparing release/libtool/so numbers, and how to use them in autoconf scripts). - The installation documentation has been seriously revamped. Everything is now in the `docs' directory. ====================================================================== CHANGES BETWEEN 2.1.3 and 2.1.2 I. IMPORTANT BUG FIXES - FT_Vector_Transform had been incorrectly modified in 2.1.2, resulting in incorrect transformations being applied (for example, rotations were processed in opposite angles). - The format 8 and 12 TrueType charmap enumeration routines have been fixed (FT_Get_Next_Char returned invalid values). - The PFR font driver returned incorrect advance widths if the outline and metrics resolution defined in the font file were different. - FT_Glyph_To_Bitmap now returns successfully when called with an FT_BitmapGlyph argument (it previously returned an error). - A bug in the Type 1 loader that prevented valid font bounding boxes to be loaded from multiple master fonts. - The SFNT validation code has been rewritten. FreeType can now load `broken' fonts that were usable on Windows, but not with previous versions of the library. - The computation of bearings in the BDF driver has been fixed. - The Postscript hinter crashed when trying to hint certain glyphs (more precisely, when trying to apply hints to an empty glyph outline). - The TrueType glyph loader now supports composites in `Apple format' (they differ slightly from Microsoft/OpenType ones in the way transformation offsets are computed). - FreeType was very slow at opening certain asian CID/CFF fonts, due to fixed increment in dynamic array re-allocations. This has been changed to exponential behaviour to get acceptable performance. II. IMPORTANT CHANGES - The PCF driver now supports gzip-compressed font files natively. This means that you will be able to use all these bitmap fonts that come with XFree86 with FreeType (and libXft/libXft2, by extension). - The automatic and postscript hinters have both been updated. This results in a relatively important increase of rendering quality since many nasty defaults have been suppressed. Please visit the web page: https://www.freetype.org/hinting/smooth-hinting.html for additional details on this topic. - The `load_flags' parameter of `FT_Load_Glyph' is now an FT_Int32 (instead of just being an FT_Int). This breaks source and binary compatibility for 16bit systems only, while retaining both of them for 32 and 64 bit ones. Some new flags have been added consequently: FT_LOAD_NO_AUTOHINT :: Disable the use of the auto-hinter (but not native format hinters). FT_LOAD_TARGET_NORMAL :: Hint and render for normal anti-aliased displays. FT_LOAD_TARGET_MONO :: Hint and render for 1-bit displays. FT_LOAD_TARGET_LCD :: Hint and render for horizontal RGB or BGR subpixel displays (like LCD screens). THIS IS STILL EXPERIMENTAL! FT_LOAD_TARGET_LCD_V :: Same as FT_LOAD_TARGET_LCD, for vertical subpixel displays (like rotated LCD screens). THIS IS STILL EXPERIMENTAL! FT_LOAD_MONOCHROME is still supported, but only affects rendering, not the hinting. Note that the `ftview' demo program available in the `ft2demos' package has been updated to support LCD-optimized display on non-paletted displays (under Win32 and X11). - The PFR driver now supports embedded bitmaps (all formats supported), and returns correct kerning metrics for all glyphs. - The TrueType charmap loader now supports certain `broken' fonts that load under Windows without problems. - The cache API has been slightly modified (it's still a beta!): - The type FTC_ImageDesc has been removed; it is now replaced by FTC_ImageTypeRec. Note that one of its fields is a `load_flag' parameter for FT_Load_Glyph. - The field `num_grays' of FT_SBitRec has been changed to `max_grays' in order to fit within a single byte. Its maximum value is thus 255 (instead of 256 as previously). III. MISCELLANEOUS - Added support for the DESTDIR variable during `make install'. This simplifies packaging of FreeType. - Included modified copies of the ZLib sources in `src/gzip' in order to support gzip-compressed PCF fonts. We do not use the system-provided zlib for now, though this is a probable enhancement for future releases. - The DocMaker tool used to generate the on-line API reference has been completely rewritten. It is now located in `src/tools/docmaker/docmaker.py'. Features: - better cross-referenced output - more polished output - uses Python regular expressions (though it didn't speed the program) - much more modular structure, which allows for different `backends' in order to generate HTML, XML, or whatever format. One can regenerate the API reference by calling: python src/tools/docmaker/docmaker.py \ --prefix=ft2 \ --title=FreeType-2.1.3 \ --output=<outputdirectory> include/freetype/*.h \ include/freetype/config/*.h \ include/freetype/cache/*.h - A new, experimental, support for incremental font loading (i.e., loading of fonts where the glyphs are not in the font file itself, but provided by an external component, like a Postscript interpreter) has been added by Graham Asher. This is still work in progress, however. - A new, EXPERIMENTAL, path stroker has been added. It doesn't suffer from severe rounding errors and treat bezier arcs directly. Still work in progress (i.e. not part of the official API). See the file <freetype/ftstroker.h> for some of the details. - The massive re-formatting of sources and internal re-design is still under-way. Many internal functions, constants, and types have been renamed. ====================================================================== CHANGES BETWEEN 2.1.2 and 2.1.1 I. IMPORTANT BUG FIXES - Many font drivers didn't select a Unicode charmap by default when a new face was opened (with the FT_CONFIG_OPTION_USE_CMAPS options enabled), causing many applications to not be able to display text correctly with the 2.1.x releases. - The PFR driver had a bug in its composite loading code that produces incorrectly placed accents with many fonts. - The Type42 driver crashed sometimes due to a nasty bug. - The Type 1 custom encoding charmap didn't handle the case where the first glyph index wasn't 0. - A serious typo in the TrueType composite loader produced incorrectly placed glyphs in fonts like `Wingdings' and a few others. II. MISCELLANEOUS - The Win32 Visual C++ project file has been updated to include the PFR driver as well. - `freetype.m4' is now installed by default by `make install' on Unix systems. - The function FT_Get_PS_Font_Info now works with CID and Type42 fonts as well. ====================================================================== CHANGES BETWEEN 2.1.1 and 2.1.0 I. IMPORTANT BUG FIXES - The `version_info' returned by `freetype-config' in 2.1.0 returned an invalid value. It now returns 9:1:3 (2.0.9 returned 9:0:3). - Version 2.1.0 couldn't be linked against applications on Win32 and Amiga systems due to a new debug function that wasn't properly propagated to the system-specific directory in `builds'. - Various MacOS and Mac OS X specific fixes. - Fixed a bug in the TrueType charmap validation routines that made version 2.1.0 too restrictive -- many popular fonts have been rejected. - There was still a very small difference between the monochrome glyph bitmaps produced by FreeType 1.x and FreeType 2.x with the bytecode interpreter enabled. This was caused by an invalid flag setting in the TrueType glyph loader, making the rasterizer change its drop-out control mode. Now the results should _really_ be completely identical. - The TrueType name table loader has been improved to support many popular though buggy Asian fonts. It now ignores empty name entries, invalid pointer offsets and a few other incorrect subtleties. Moreover, name strings are now loaded on demand, which reduces the memory load of many faces (e.g. the ARIAL.TTF font file contains a 10kByte name table with 70 names). - Fixed a bug in the Postscript hinter that prevented family blues substitution to happen correctly. II. NEW FEATURES - Three new font drivers in this release: * A BDF font driver, contributed by Franco Zappa Nardelli, heavily modified by Werner Lemberg. It also supports anti-aliased bitmaps (using a slightly extended BDF format). * A Type42 font driver, contributed by Roberto Alameda. It is still experimental but seems to work relatively well. * A PFR font driver, contributed by David Turner himself. It doesn't support PFR hinting -- note that BitStream has at least two patents on this format! III. MISCELLANEOUS - The cache sub-system has been optimized in important ways. Cache hits are now significantly faster. For example, using the CMap cache is about twice faster than calling FT_Get_Char_Index on most platforms. Similarly, using an SBit cache is about five times faster than loading the bitmaps from a bitmap file, and 300 to 500 times faster than generating them from a scalable format. Note that you should recompile your sources if you designed a custom cache class for the FT2 Cache subsystem, since the changes performed are source, but not binary, compatible. ====================================================================== CHANGES BETWEEN 2.1.0 and 2.0.9 I. IMPORTANT BUG FIXES - The TrueType bytecode interpreter has been fixed to produce _exactly_ the same output as FreeType 1.x. Previous differences were due to slightly distinct fixed-point computation routines used to perform dot products and vector length measurements. It seems that native TrueType hinting is _extremely_ sensitive to rounding errors. The required vector computation routines have been optimized and placed within the `ttinterp.c' file. - Fixed the parsing of accelerator tables in the PCF font driver. - Fixed the Type1 glyph loader routine used to compute the font's maximum advance width. II. NEW FEATURES - The `configure' script used on Unix systems has been modified to check that GNU Make is being used to build the library. Otherwise, it will display a message proposing to use the GNUMAKE environment variable to name it. The Unix-specific file README.UNX has been modified accordingly. III. MISCELLANEOUS - The FreeType License in `docs/FTL.TXT' has been updated to include a proposed preferred disclaimer. If you are using FreeType in your products, you are encouraged (but not mandated) to use the following text in your documentation: """ Portions of this software are copyright © 1996-2002 The FreeType Project (www.freetype.org). All rights reserved. """ - The default size of the render pool has been reduced to 16kByte. This shouldn't result in any noticeable performance penalty, unless you are using the engine as-is to render very large and complex glyphs. - The FreeType 2 redesign has begun. More information can be found at this URL: https://www.freetype.org/freetype2/redesign.html The following internal changes have been performed within the sources of this release: - Many internal types have been renamed to increase consistency. The following should be true, except for public types: * All structure types have a name ending in `Rec' (short for `record'). * A pointer-to-structure type has the same name as the structure, _without_ the `Rec' suffix. Example: typedef struct FooRec_ { ... } FooRec, *Foo; - Many internal macros have been renamed to increase consistency. The following should be true: * All macros have a name beginning with `FT_'. This required a few changes like ALLOC => FT_ALLOC FREE => FT_FREE REALLOC => FT_REALLOC * All macros are completely UPPERCASE. This required a few changes like: READ_Short => FT_READ_SHORT NEXT_Short => FT_NEXT_SHORT GET_ULongLE => FT_GET_ULONG_LE MEM_Set => FT_MEM_SET MEM_Copy => FT_MEM_COPY etc. * Whenever possible, all macro names follow the FT_<OBJECT>_<METHOD> pattern. For example ACCESS_Frame => FT_FRAME_ENTER FORGET_Frame => FT_FRAME_EXIT EXTRACT_Frame => FT_FRAME_EXTRACT RELEASE_Frame => FT_FRAME_RELEASE FILE_Pos => FT_STREAM_POS FILE_Seek => FT_STREAM_SEEK FILE_Read => FT_STREAM_READ FILE_ReadAt => FT_STREAM_READ_AT READ_Fields => FT_STREAM_READ_FIELDS - Many internal functions have been renamed to follow the FT_<Object>_<Method> pattern. For example: FT_Seek_Stream => FT_Stream_Seek FT_Read_Stream_At => FT_Stream_ReadAt FT_Done_Stream => FT_Stream_Close FT_New_Stream => FT_Stream_Open FT_New_Memory_Stream => FT_Stream_OpenMemory FT_Extract_Frame => FT_Stream_ExtractFrame Note that method names do not contain `_'. - The FT_ALLOC_ARRAY and FT_REALLOC_ARRAY have been replaced with FT_NEW_ARRAY and FT_RENEW_ARRAY which do not take a type as the fourth argument. Instead, the array element type size is computed automatically from the type of the target pointer used. - A new object class, FT_CMap, has been introduced. These internal objects are used to model character maps. This eases the support of additional charmap types within the engine. - A new configuration file named `ftstdlib.h' has been added to `include/freetype/config'. It is used to define aliases for _every_ routine of the ISO C library that the font engine uses. Each aliases has a `ft_' prefix (e.g. `ft_strlen' is an alias for `strlen'). This is used to ease the porting of FreeType 2 to exotic runtime environments where the ISO C Library isn't available (e.g. XFree86 extension modules). More details are available in the `ChangeLog' file. ====================================================================== CHANGES BETWEEN 2.0.9 and 2.0.8 I. IMPORTANT BUG FIXES - Certain fonts like `foxjump.ttf' contain broken name tables with invalid entries and wild offsets. This caused FreeType to crash when trying to load them. The SFNT `name' table loader has been fixed to be able to support these strange fonts. Moreover, the code in charge of processing this table has been changed to always favour Windows-formatted entries over other ones. Hence, a font that works on Windows but not on the Mac will load cleanly in FreeType and report accurate values for Family & PostScript names. - The CID font driver has been fixed. It unfortunately returned a Postscript Font name with a leading slash, as in `/MunhwaGothic-Regular'. - FreeType 2 should now compile fine on AIX 4.3.3 as a shared library. - A bug in the Postscript hinter has been found and fixed, removing un-even stem widths at small pixel sizes (like 14-17). This improves the quality of a certain number of Postscript fonts. II. NEW FEATURES - A new function named `FT_Library_Version' has been added to return the current library's major, minor, and patch version numbers. This is important since the macros FREETYPE_MAJOR, FREETYPE_MINOR, and FREETYPE_PATCH cannot be used when the library is dynamically linked by a program. - Two new APIs have been added: `FT_Get_First_Char' and `FT_Get_Next_Char'. Together, these can be used to iterate efficiently over the currently selected charmap of a given face. Read the API reference for more details. III. MISCELLANEOUS - The FreeType sources are under heavy internal re-factoring. As a consequence, we have created a branch named `STABLE' on the CVS to hold all future releases/fixes in the 2.0.x family. The HEAD branch now contains the re-factored sources and shouldn't be used for testing or packaging new releases. In case you would like to access the 2.0.9 sources from our CVS repository, use the tag `VER-2-0-9'. ====================================================================== CHANGES BETWEEN 2.0.8 and 2.0.7 I. IMPORTANT BUG FIXES - There was a small but nasty bug in `freetype-config.in' which caused the `freetype-config' script to fail on Unix. This didn't prevent the installation of the library or even its execution, but caused problems when trying to compile many Unix packages that depend on it. - Some TrueType or OpenType fonts embedded in PDF documents do not have a 'cmap', 'post' and 'name' as is required by the specification. FreeType no longer refuses to load such fonts. - Various fixes to the PCF font driver. ====================================================================== CHANGES BETWEEN 2.0.7 and 2.0.6 I. IMPORTANT BUG FIXES - Fixed two bugs in the Type 1 font driver. The first one resulted in a memory leak in subtle cases. The other one caused FreeType to crash when trying to load `.gsf' files (Ghostscript so-called Postscript fonts). (This made _many_ KDE applications crash on certain systems. FreeType _is_ becoming a critical system component on Linux :-) - Fixed a memory leak in the CFF font driver. - Fixed a memory leak in the PCF font driver. - Fixed the Visual C++ project file `builds/win32/visualc/freetype.dsp' since it didn't include the Postscript hinter component, causing errors at build time. - Fixed a small rendering bug in the anti-aliased renderer that only occurred when trying to draw thin (less than 1 pixel) strokes. - Fixed `builds/unix/freetype2.a4' which is used to generate a valid `freetype2.m4' for use with autoconf. - Fixed the OpenVMS Makefiles. II. MISCELLANEOUS - Added `configure' and `install' scripts to the top-level directory. A GNU-style installation is thus now easily possible with ./configure <options> make make install ====================================================================== CHANGES BETWEEN 2.0.6 and 2.0.5 I. IMPORTANT BUG FIXES - It wasn't possible to load embedded bitmaps when the auto-hinter was used. This is now fixed. - The TrueType font driver didn't load some composites properly (the sub-glyphs were slightly shifted, and this was only noticeable when using monochrome rendering). - Various fixes to the auto-hinter. They merely improve the output of sans-serif fonts. Note that there are still problems with serifed fonts and composites (accented characters). - All scalable font drivers erroneously returned un-fitted glyph advances when hinting was requested. This created problems for a number of layout applications. This is a very old bug that got undetected mainly because most test/demo program perform rounding explicitly or implicitly (through the cache). - `FT_Glyph_To_Bitmap' did erroneously modify the source glyph in certain cases. - `glnames.py' still contained a bug that made FreeType return invalid names for certain glyphs. - The library crashed when loading certain Type 1 fonts like `sadn.pfb' (`Stalingrad Normal'), which appear to contain pathetic font info dictionaries. - The TrueType glyph loader is now much more paranoid and checks everything when loading a given glyph image. This was necessary to avoid problems (crashes and/or memory overwrites) with broken fonts that came from a really buggy automatic font converter. II. IMPORTANT UPDATES AND NEW FEATURES - Important updates to the Mac-specific parts of the library. - The caching sub-system has been completely re-designed, and its API has evolved (the old one is still supported for backward compatibility). The documentation for it is not yet completed, sorry. For now, you are encouraged to continue using the old API. However, the ftview demo program in the ft2demos package has already been updated to use the new caching functions. - A new charmap cache is provided too. See `FTC_CMapCache'. This is useful to perform character code -> glyph index translations quickly, without the need for an opened FT_Face. - A NEW POSTSCRIPT HINTER module has been added to support native hints in the following formats: PostScript Type 1, PostScript CID, and CFF/CEF. Please test! Note that the auto-hinter produces better results for a number of badly-hinted fonts (mostly auto-generated ones) though. - A memory debugger is now part of the standard FreeType sources. To enable it, define FT_DEBUG_MEMORY in <freetype/config/ftoption.h>, and recompile the library. Additionally, define the _environment_ variable FT_DEBUG_MEMORY and run any program using FreeType. When the library is exited, a summary of memory footprints and possible leaks will be displayed. This works transparently with _any_ program that uses FreeType. However, you will need a lot of memory to use this (allocated blocks are never released to the heap to detect double deletes easily). III. MISCELLANEOUS - We are aware of subtle differences between the output of FreeType versions 1 and 2 when it comes to monochrome TrueType-hinted glyphs. These are most probably due to small differences in the monochrome rasterizers and will be worked out in an upcoming release. - We have decided to fork the sources in a `stable' branch, and an `unstable' one, since FreeType is becoming a critical component of many Unix systems. The next bug-fix releases of the library will be named 2.0.7, 2.0.8, etc., while the `2.1' branch will contain a version of the sources where we will start major reworking of the library's internals, in order to produce FreeType 2.2.0 (or even 3.0) in a more distant future. We also hope that this scheme will allow much more frequent releases than in the past. ====================================================================== CHANGES BETWEEN 2.0.5 and 2.0.4 NOTE THAT 2.0.5 DOES NOT CONTAIN THE POSTSCRIPT HINTER. THIS MODULE WILL BE PART OF THE NEXT RELEASE (EITHER 2.0.6 or 2.1) - Fixed a bug that made certain glyphs, like `Cacute', `cacute' and `lslash' unavailable from Unicode charmaps of Postscript fonts. This prevented the correct display of Polish text, for example. - The kerning table of Type 1 fonts was loaded by FreeType, when its AFM file was attached to its face, but the FT_FACE_FLAG_HAS_KERNING bit flags was not set correctly, preventing FT_Get_Kerning to return meaningful values. - Improved SFNT (TrueType & OpenType) charmap support. Slightly better performance, as well as support for the new formats defined by the OpenType 1.3 specification (8, 10, and 12) - Fixed a serious typo in `src/base/ftcalc.c' which caused invalid computations in certain rare cases, producing ugly artefacts. - The size of the EM square is computed with a more accurate algorithm for Postscript fonts. The old one caused slight errors with embedded fonts found in PDF documents. - Fixed a bug in the cache manager that prevented normal LRU behaviour within the cache manager, causing unnecessary reloads (for FT_Face and FT_Size objects only). - Added a new function named `FT_Get_Name_Index' to retrieve the glyph index of a given glyph name, when found in a face. - Added a new function named `FT_Get_Postscript_Name' to retrieve the `unique' Postscript font name of a given face. - Added a new public header size named FT_SIZES_H (or <freetype/ftsizes.h>) providing new FT_Size-management functions: FT_New_Size, FT_Activate_Size, FT_Done_Size. - Fixed a reallocation bug that generated a dangling pointer (and possibly memory leaks) with Postscript fonts (in src/psaux/psobjs.c). - Many fixes for 16-bit correctness. - Removed many pedantic compiler warnings from the sources. - Added an Amiga build directory in `builds/amiga'. ====================================================================== CHANGES BETWEEN 2.0.4 and 2.0.3 - Fixed a rather annoying bug that was introduced in 2.0.3. Namely, the font transformation set through FT_Set_Transform was applied twice to auto-hinted glyphs, resulting in incorrectly rotated text output. - Fixed _many_ compiler warnings. FT2 should now compile cleanly with Visual C++'s most pedantic warning level (/W4). It already compiled fine with GCC and a few other compilers. - Fixed a bug that prevented the linear advance width of composite TrueType glyphs to be correctly returned. - Fixed the Visual C++ project files located in `builds/win32/visualc' (previous versions used older names of the library). - Many 32-bit constants have an `L' appended to their value, in order to improve the 16-bitness of the code. Someone is actually trying to use FT2 on an Atari ST machine! - Updated the `builds/detect.mk' file in order to automatically build FT2 on AIX systems. AIX uses `/usr/sbin/init' instead of `/sbin/init' and wasn't previously detected as a Unix platform by the FreeType build system. - Updated the Unix-specific portions of the build system (new libtool version, etc.). - The SFNT kerning loader now ensures that the table is sorted (since some problem fonts do not meet this requirement). ======================================================================= CHANGES BETWEEN 2.0.3 and 2.0.2 I. CHANGES TO THE MODULES / FONT DRIVERS - THE AUTO-HINTER HAS BEEN SLIGHTLY IMPROVED, in order to fix several annoying artefacts, mainly: - Blue zone alignment of horizontal stems wasn't performed correctly, resulting in artefacts like the `d' being placed one pixel below the `b' in some fonts like Time New Roman. - Overshoot thresholding wasn't performed correctly, creating unpleasant artefacts at large character pixel sizes. - Composite glyph loading has been simplified. This gets rid of various artefacts where the components of a composite glyphs were not correctly spaced. These are the last changes to the current auto-hinting module. A new hinting sub-system is currently in the work in order to support native hints in Type 1 / CFF / OpenType fonts, as well as globally improve rendering. - The PCF driver has been fixed. It reported invalid glyph dimensions for the fonts available on Solaris. - The Type 1, CID and CFF drivers have been modified to fix the computation of the EM size. - The Type 1 driver has been fixed to avoid a dangerous bug that crashed the library with non-conforming fonts (i.e. ones that do not place the .notdef glyph at position 0). - The TrueType driver had a rather subtle bug (dangling pointer when loading composite glyphs) that could crash the library in rare occasions! II. HIGH-LEVEL API CHANGES - The error code enumeration values have been changed. An error value is decomposed in a generic error code, and a module number. see <freetype/fterrors.h> for details. - A new public header file has been introduced, named FT_TRIGONOMETRY_H (include/freetype/fttrigon.h), providing trigonometric functions to compute sines, cosines, arctangents, etc. with 16.16 fixed precision. The implementation is based on the CORDIC algorithm and is very fast while being sufficiently accurate. III. INTERNALS - Added BeOS-specific files in the old build sub-system. Note that no changes were required to compile the library with Jam. - The configuration is now capable of automatically detecting 64-bit integers on a set of predefined compilers (GCC, Visual C++, Borland C++) and will use them by default. This provides a small performance boost. - A small memory leak that happened when opening 0-sized files (duh!) have been fixed. - Fixed bezier stack depth bug in the routines provided by the FT_BBOX_H header file. Also fixed similar bugs in the rasterizers. - The outline bounding box code has been rewritten to use direct computations, instead of bezier sub-division, to compute the exact bounding box of glyphs. This is slightly slower but more accurate. - The build system has been improved and fixed, mainly to support `make' on Windows 2000 correctly, avoid problems with `make distclean' on non Unix systems, etc. - Hexadecimal constants have been suffixed with `U' to avoid problems with certain compilers on 64-bit platforms. - A new directory named `src/tools' has been created. It contains Python scripts and simple unit test programs used to develop the library. - The DocMaker tool has been moved from `docs' to `src/tools' and has been updated with the following: - Now accepts the `--title=XXXX' or `-t XXXX' option from the command line to set the project's name in the generated API reference. - Now accepts the `--output=DIR' or `-o DIR' option from the command line to set the output directory for all generated HTML files. - Now accepts the `--prefix=XXXX' or `-p XXX' option from the command line to set the file prefix to use for all generated HTML files. - Now generates the current time/data on each generated page in order to distinguish between versions. DocMaker can be used with other projects now, not only FT2 (e.g. MLib, FTLayout, etc.). ====================================================================== CHANGES BETWEEN 2.0.2 and 2.0.1 I. CHANGES TO THE MODULES / FONT DRIVERS - THE TRUETYPE BYTECODE INTERPRETER IS NOW TURNED OFF, in order to avoid legal problems with the Apple patents. It seems that we mistakenly turned this option on in previous releases of the build. Note that if you want to use the bytecode interpreter in order to get high-quality TrueType rendering, you will need to toggle by hand the definition of the TT_CONFIG_OPTION_BYTECODE_INTERPRETER macro in the file `include/freetype/config/ftoption.h'. - The CFF driver has been improved by Tom Kacvinsky and Sander van der Wal: * Support for `seac' emulation. * Support for `dotsection'. * Support for retrieving glyph names through `FT_Get_Glyph_Name'. The first two items are necessary to correctly a large number of Type 1 fonts converted to the CFF formats by Adobe Acrobat. - The Type 1 driver was also improved by Tom & others: * Better EM size computation. * Better support for synthetic (transformed) fonts. * The Type 1 driver returns the charstrings corresponding to each glyph in the `glyph->control_data' field after a call to `FT_Load_Glyph' (thanks Ha Shao). - Various other bugfixes, including the following: * Fixed a nasty memory leak in the Type 1 driver. * The autohinter and the pcf driver used static writable data when they shouldn't. * Many casts were added to make the code more 64-bits safe. It also now compiles on Windows XP 64-bits without warnings. * Some incorrect writable statics were removed in the `autohint' and `pcf' drivers. FreeType 2 now compiles on Epoc again. II. CHANGES TO THE HIGH-LEVEL API - The library header files inclusion scheme has been changed. The old scheme looked like: #include <freetype/freetype.h> #include <freetype/ftglyph.h> #include <freetype/ftcache.h> #include <freetype/cache/ftimage.h> Now you should use: #include <ft2build.h> #include FT_FREETYPE_H #include FT_GLYPH_H #include FT_CACHE_H #include FT_CACHE_IMAGE_H NOTE THAT THE OLD INCLUSION SCHEME WILL STILL WORK WITH THIS RELEASE. HOWEVER, WE DO NOT GUARANTEE THAT THIS WILL STILL BE TRUE IN THE NEXT ONE (A.K.A. FREETYPE 2.1). The file <ft2build.h> is used to define the header filename macros. The complete and commented list of macros is available in the API reference under the section name `Header File Macros' in Chapter I. For more information, see section I of the following document: https://www.freetype.org/freetype2/docs/tutorial/step1.html - Many, many comments have been added to the public source file in order to automatically generate the API Reference through the `docmaker.py' Python script. The latter has been updated to support the grouping of sections in chapters and better index sort. See: https://www.freetype.org/freetype2/docs/reference/ft2-toc.html III. CHANGES TO THE BUILD PROCESS - If you are not building FreeType 2 with its own build system (but with your own Makefiles or project files), you will need to be aware that the build process has changed a little bit. You don't need to put the `src' directory in the include path when compiling any FT2 component. Instead, simply put the component's directory in the current include path. So, if you were doing something like: cc -c -Iinclude -Isrc src/base/ftbase.c change the line to: cc -c -Iinclude -Isrc/base src/base/ftbase.c If you were doing something like: cd src/base cc -c -I../../include -I.. ftbase.c change it to: cd src/base cc -c -I../../include ftbase.c ====================================================================== CHANGES BETWEEN 2.0.1 and 2.0 2.0.1 introduces a few changes: - Fixed many bugs related to the support of CFF / OpenType fonts. These formats are now much better supported though there is still work planned to deal with charset tables and PDF-embedded CFF files that use the old `seac' command. - The library could not be compiled in debug mode with a very small number of C compilers whose pre-processors didn't implement the `##' directive correctly (i.e. per se the ANSI C specification!) An elegant fix was found. - Added support for the free Borland command-line C++ Builder compiler. Use `make setup bcc32'. Also fixed a few source lines that generated new warnings with BCC32. - Fixed a bug in FT_Outline_Get_BBox when computing the extrema of a conic Bezier arc. - Updated the INSTALL file to add IDE compilation. - Other minor bug fixes, from invalid Type 1 style flags to correct support of synthetic (obliqued) fonts in the auto-hinter, better support for embedded bitmaps in a SFNT font. - Fixed some problems with `freetype-config'. Finally, the `standard' scheme for including FreeType headers is now gradually changing, but this will be explained in a later release (probably 2.0.2). And very special thanks to Tom Kacvinsky and YAMANO-UCHI Hidetoshi for their contributions! ====================================================================== CHANGES BETWEEN beta8 and 2.0 - Changed the default installation path for public headers from `include/freetype' to `include/freetype2'. Also added a new `freetype-config' that is automatically generated and installed on Unix and Cygwin systems. The script itself is used to retrieve the current install path, C compilation flags as well as linker flags. - Fixed several small bugs: * Incorrect max advance width for fixed-pitch Type 1 fonts. * Incorrect glyph names for certain TrueType fonts. * The glyph advance was not copied when FT_Glyph_To_Bitmap was called. * The linearHoriAdvance and linearVertAdvance fields were not correctly returned for glyphs processed by the auto-hinter. * `type1z' renamed back to `type1'; the old `type1' module has been removed. - Revamped the build system to make it a lot more generic. This will allow us to re-use nearly un-modified in lots of other projects (including FreeType Layout). - Changed `cid' to use `psaux' too. - Added the cache sub-system. See <freetype/ftcache.h> as well as the sources in `src/cache'. Note that it compiles but is still untested for now. - Updated `docs/docmaker.py', a draft API reference is available at https://web.archive.org/web/20001215173400/http://www.freetype.org:80/ft2api.html. - Changed `type1' to use `psaux'. - Created a new module named `psaux' to hold the Type 1 & Type 2 parsing routines. It should be used by `type1', `cid', and `cff' in the future. - Fixed an important bug in `FT_Glyph_Get_CBox'. - Fixed some compiler warnings that happened since the TrueType bytecode decoder was deactivated by default. - Fixed two memory leaks: * The memory manager (16 bytes) isn't released in FT_Done_FreeType! * Using custom input streams, the copy of the original stream was never released. - Fixed the auto-hinter by performing automatic computation of the `filling direction' of each glyph. This is done through a simple and fast approximation, and seems to work (problems spotted by Werner though). The Arphic fonts are a lot nicer though there are still a lot of things to do to handle Asian fonts correctly. ====================================================================== BETA-8 (RELEASE CANDIDATE) CHANGES - Deactivated the TrueType bytecode interpreter by default. - Deactivated the `src/type1' font driver. Now `src/type1z' is used by default. - Updates to the build system. We now compile the library correctly under Unix system through `configure' which is automatically called on the first `make' invocation. - Added the auto-hinting module! Fixing some bugs here and there. - Found some bugs in the composite loader (seac) of the Type1-based font drivers. - Renamed the directory `freetype2/config' to `freetype2/builds' and updated all relevant files. - Found a memory leak in the `type1' driver. - Incorporated Tom's patches to support flex operators correctly in OpenType/CFF fonts. Now all I need is to support pure CFF and CEF fonts to be done with this driver :-) - Added the Windows FNT/FON driver in `src/winfonts'. For now, it always `simulates' a Unicode charmap, so it shouldn't be considered completed right now. It is there to be more a proof of concept than anything else anyway. The driver is a single C source file, that compiles to 3 Kb of code. I'm still working on the PCF/BDF drivers, but I'm too lazy to finish them now. - CHANGES TO THE HIGH-LEVEL API * FT_Get_Kerning has a new parameter that allows you to select the coordinates of the kerning vector (font units, scaled, scaled + grid-fitted). * The outline functions are now in <freetype/ftoutln.h> and not part of <freetype/freetype.h> anymore. * <freetype/ftmodule.h> now contains declarations for FT_New_Library, FT_Done_Library, FT_Add_Default_Modules. * The so-called convenience functions have moved from `ftoutln.c' to `ftglyph.c', and are thus available with this optional component of the library. They are declared in <freetype/ftglyph.h> now. * Anti-aliased rendering is now the default for FT_Render_Glyph (i.e. corresponds to render_mode == 0 == ft_render_mode_normal). To generate a monochrome bitmap, use ft_render_mode_mono, or the FT_LOAD_MONOCHROME flag in FT_Load_Glyph/FT_Load_Char. FT_LOAD_ANTI_ALIAS is still defined, but values to 0. * <freetype/freetype.h> now include <freetype/config/ftconfig.h>, solving a few headaches :-) * The type FT_GlyphSlotRec has now a `library' field. - CHANGES TO THE `ftglyph.h' API This API has been severely modified in order to make it simpler, clearer, and more efficient. It certainly now looks like a real `glyph factory' object, and allows client applications to manage (i.e. transform, bbox and render) glyph images without ever knowing their original format. - Added support for CID-keyed fonts to the CFF driver. Maybe support for pure CFF + CEF fonts should come in? - Cleaned up source code in order to avoid two functions with the same name. Also changed the names of the files in `type1z' from `t1XXXX' to `z1XXXX' in order to avoid any conflicts. `make multi' now works well :-) Also removed the use of `cidafm' for now, even if the source files are still there. This functionality will certainly go into a specific module. - ADDED SUPPORT FOR THE AUTO-HINTER It works :-) I have a demo program which simply is a copy of `ftview' that does a `FT_Add_Module(library, &autohinter_module_class)' after library initialization, and Type 1 & OpenType/CFF fonts are now hinted. CID fonts are not hinted, as they include no charmap and the auto-hinter doesn't include `generic' global metrics computations yet. Now, I need to release this thing to the FreeType 2 source. - CHANGES TO THE RENDERER MODULES The monochrome and smooth renderers are now in two distinct directories, namely `src/raster1' and `src/smooth'. Note that the old `src/renderer' is now gone. I ditched the 5-gray-levels renderers. Basically, it involved a simple #define toggle in 'src/raster1/ftraster.c'. FT_Render_Glyph, FT_Outline_Render & FT_Outline_Get_Bitmap now select the best renderer available, depending on render mode. If the current renderer for a given glyph image format isn't capable of supporting the render mode, another one will be found in the library's list. This means that client applications do not need to switch or set the renderers themselves (as in the latest change), they'll get what they want automatically. At last. Changed the demo programs accordingly. - MAJOR INTERNAL REDESIGN: A lot of internal modifications have been performed lately on the source in order to provide the following enhancements: * More generic module support: The FT_Module type is now defined to represent a handle to a given module. The file <freetype/ftmodule.h> contains the FT_Module_Class definition, as well as the module-loading public API. The FT_Driver type is still defined, and still represents a pointer to a font driver. Note that FT_Add_Driver is replaced by FT_Add_Module, FT_Get_Driver by FT_Get_Module, etc. * Support for generic glyph image types: The FT_Renderer type is a pointer to a module used to perform various operations on glyph image. Each renderer is capable of handling images in a single format (e.g. ft_glyph_format_outline). Its functions are used to: - transform an glyph image - render a glyph image into a bitmap - return the control box (dimensions) of a given glyph image The scan converters `ftraster.c' and `ftgrays.c' have been moved to the new directory `src/renderer', and are used to provide two default renderer modules. One corresponds to the `standard' scan-converter, the other to the `smooth' one. he current renderer can be set through the new function FT_Set_Renderer. The old raster-related function FT_Set_Raster, FT_Get_Raster and FT_Set_Raster_Mode have now disappeared, in favor of the new: FT_Get_Renderer FT_Set_Renderer See the file <freetype/ftrender.h> for more details. These changes were necessary to properly support different scalable formats in the future, like bi-color glyphs, etc. * Glyph loader object: A new internal object, called a 'glyph loader' has been introduced in the base layer. It is used by all scalable format font drivers to load glyphs and composites. This object has been created to reduce the code size of each driver, as each one of them basically re-implemented its functionality. See <freetype/internal/ftobjs.h> and the FT_GlyphLoader type for more information. * FT_GlyphSlot has new fields: In order to support extended features (see below), the FT_GlyphSlot structure has a few new fields: linearHoriAdvance: This field gives the linearly scaled (i.e. scaled but unhinted) advance width for the glyph, expressed as a 16.16 fixed pixel value. This is useful to perform WYSIWYG text. linearVertAdvance: This field gives the linearly scaled advance height for the glyph (relevant in vertical glyph layouts only). This is useful to perform WYSIWYG text. Note that the two above field replace the removed `metrics2' field in the glyph slot. advance: This field is a vector that gives the transformed advance for the glyph. By default, it corresponds to the advance width, unless FT_LOAD_VERTICAL_LAYOUT was specified when calling FT_Load_Glyph or FT_Load_Char. bitmap_left: This field gives the distance in integer pixels from the current pen position to the left-most pixel of a glyph image IF IT IS A BITMAP. It is only valid when the `format' field is set to `ft_glyph_format_bitmap', for example, after calling the new function FT_Render_Glyph. bitmap_top: This field gives the distance in integer pixels from the current pen position (located on the baseline) to the top-most pixel of the glyph image IF IT IS A BITMAP. Positive values correspond to upwards Y. loader: This is a new private field for the glyph slot. Client applications should not touch it. * Support for transforms and direct rendering in FT_Load_Glyph: Most of the functionality found in <freetype/ftglyph.h> has been moved to the core library. Hence, the following: - A transform can be specified for a face through FT_Set_Transform. this transform is applied by FT_Load_Glyph to scalable glyph images (i.e. NOT TO BITMAPS) before the function returns, unless the bit flag FT_LOAD_IGNORE_TRANSFORM was set in the load flags. - Once a glyph image has been loaded, it can be directly converted to a bitmap by using the new FT_Render_Glyph function. Note that this function takes the glyph image from the glyph slot, and converts it to a bitmap whose properties are returned in `face.glyph.bitmap', `face.glyph.bitmap_left' and `face.glyph.bitmap_top'. The original native image might be lost after the conversion. - When using the new bit flag FT_LOAD_RENDER, the FT_Load_Glyph and FT_Load_Char functions will call FT_Render_Glyph automatically when needed. - Reformatted all modules source code in order to get rid of the basic data types redefinitions (i.e. `TT_Int' instead of `FT_Int', `T1_Fixed' instead of `FT_Fixed'). Hence the format-specific prefixes like `TT_', `T1_', `T2_' and `CID_' are only used for relevant structures. ====================================================================== OLD CHANGES FOR BETA 7 - bug-fixed the OpenType/CFF parser. It now loads and displays my two fonts nicely, but I'm pretty certain that more testing is needed :-) - fixed the crummy Type 1 hinter, it now handles accented characters correctly (well, the accent is not always well placed, but that's another problem..) - added the CID-keyed Type 1 driver in `src/cid'. Works pretty well for only 13 Kb of code ;-) Doesn't read AFM files though, nor the really useful CMAP files.. - fixed two bugs in the smooth renderer (src/base/ftgrays.c). Thanks to Boris Letocha for spotting them and providing a fix. - fixed potential `divide by zero' bugs in ftcalc.c. - added source code for the OpenType/CFF driver (still incomplete though..) - modified the SFNT driver slightly to perform more robust header checks in TT_Load_SFNT_Header. This prevents certain font files (e.g. some Type 1 Multiple Masters) from being incorrectly `recognized' as TrueType font files.. - moved a lot of stuff from the TrueType driver to the SFNT module, this allows greater code re-use between font drivers (e.g. TrueType, OpenType, Compact-TrueType, etc..) - added a tiny segment cache to the SFNT Charmap 4 decoder, in order to minimally speed it up.. - added support for Multiple Master fonts in `type1z'. There is also a new file named <freetype/ftmm.h> which defines functions to manage them from client applications. The new file `src/base/ftmm.c' is also optional to the engine.. - various formatting changes (e.g. EXPORT_DEF -> FT_EXPORT_DEF) + small bug fixes in FT_Load_Glyph, the `type1' driver, etc.. - a minor fix to the Type 1 driver to let them apply the font matrix correctly (used for many oblique fonts..) - some fixes for 64-bit systems (mainly changing some FT_TRACE calls to use %p instead of %lx). Thanks to Karl Robillard. - fixed some bugs in the sbit loader (src/base/sfnt/ttsbit.c) + added a new flag, FT_LOAD_CROP_BITMAP to query that bitmaps be cropped when loaded from a file (maybe I should move the bitmap cropper to the base layer ??). - changed the default number of gray levels of the smooth renderer to 256 (instead of the previous 128). Of course, the human eye can't see any difference ;-) - removed TT_MAX_SUBGLYPHS, there is no static limit on the number of subglyphs in a TrueType font now.. ====================================================================== OLD CHANGES 16 May 2000 - tagged `BETA-6' in the CVS tree. This one is a serious release candidate even though it doesn't incorporate the auto-hinter yet.. - various obsolete files were removed, and copyright header updated - finally updated the standard raster to fix the monochrome rendering bug + re-enable support for 5-gray levels anti-aliasing (suck, suck..) - created new header files, and modified sources accordingly: <freetype/fttypes.h> - simple FreeType types, without the API <freetype/internal/ftmemory.h> - definition of memory-management macros - added the `DSIG' (OpenType Digital Signature) tag to <freetype/tttags.h> - light update/cleaning of the build system + changes to the sources in order to get rid of _all_ compiler warnings with three compilers, i.e: gcc with `-ansi -pedantic -Wall -W', Visual C++ with `/W3 /WX' and LCC IMPORTANT NOTE FOR WIN32-LCC USERS: | | It seems the C pre-processor that comes with LCC is broken, it | doesn't recognize the ANSI standard directives # and ## | correctly when one of the argument is a macro. Also, | something like: | | #define F(x) print##x | | F(("hello")) | | will get incorrectly translated to: | | print "hello") | | by its pre-processor. For this reason, you simply cannot build | FreeType 2 in debug mode with this compiler.. - yet another massive grunt work. I've changed the definition of the EXPORT_DEF, EXPORT_FUNC, BASE_DEF & BASE_FUNC macros. These now take an argument, which is the function's return value type. This is necessary to compile FreeType as a DLL on Windows and OS/2. Depending on the compiler used, a compiler-specific keyword like __export or __system must be placed before (VisualC++) or after (BorlandC++) the type.. Of course, this needed a lot of changes throughout the source code to make it compile again... All cleaned up now, apparently.. Note also that there is a new EXPORT_VAR macro defined to allow the _declaration_ of an exportable public (constant) variable. This is the case of the raster interfaces (see ftraster.h and ftgrays.h), as well as each module's interface (see sfdriver.h, psdriver.h, etc..) - new feature: it is now possible to pass extra parameters to font drivers when creating a new face object. For now, this capability is unused. It could however prove to be useful in a near future.. the FT_Open_Args structure was changes, as well as the internal driver interface (the specific `init_face' module function has now a different signature). - updated the tutorial (not finished though). - updated the top-level BUILD document - fixed a potential memory leak that could occur when loading embedded bitmaps. - added the declaration of FT_New_Memory_Face in <freetype/freetype.h>, as it was missing from the public header (the implementation was already in `ftobjs.c'). - the file <freetype/fterrors.h> has been seriously updated in order to allow the automatic generation of error message tables. See the comments within it for more information. - major directory hierarchy re-organisation. This was done for two things: * first, to ease the `manual' compilation of the library by requiring at lot less include paths :-) * second, to allow external programs to effectively access internal data fields. For example, this can be extremely useful if someone wants to write a font producer or a font manager on top of FreeType. Basically, you should now use the 'freetype/' prefix for header inclusion, as in: #include <freetype/freetype.h> #include <freetype/ftglyph.h> Some new include sub-directories are available: a. the `freetype/config' directory, contains two files used to configure the build of the library. Client applications should not need to look at these normally, but they can if they want. #include <freetype/config/ftoption.h> #include <freetype/config/ftconfig.h> b. the `freetype/internal' directory, contains header files that describes library internals. These are the header files that were previously found in the `src/base' and `src/shared' directories. As usual, the build system and the demos have been updated to reflect the change.. Here's a layout of the new directory hierarchy: TOP_DIR include/ freetype/ freetype.h ... config/ ftoption.h ftconfig.h ftmodule.h internal/ ftobjs.h ftstream.h ftcalc.h ... src/ base/ ... sfnt/ psnames/ truetype/ type1/ type1z/ Compiling a module is now much easier, for example, the following should work when in the TOP_DIR directory on an ANSI build: gcc -c -I./include -I./src/base src/base/ftbase.c gcc -c -I./include -I./src/sfnt src/sfnt/sfnt.c etc.. (of course, using -Iconfig/<system> if you provide system-specific configuration files). - updated the structure of FT_Outline_Funcs in order to allow direct coordinate scaling within the outline decomposition routine (this is important for virtual `on' points with TrueType outlines) + updates to the rasters to support this.. - updated the OS/2 table loading code in `src/sfnt/ttload.c' in order to support version 2 of the table (see OpenType 1.2 spec) - created `include/tttables.h' and `include/t1tables.h' to allow client applications to access some of the SFNT and T1 tables of a face with a procedural interface (see `FT_Get_Sfnt_Table') + updates to internal source files to reflect the change.. - some cleanups in the source code to get rid of warnings when compiling with the `-Wall -W -ansi -pedantic' options in gcc. - debugged and moved the smooth renderer to `src/base/ftgrays.c' and its header to `include/ftgrays.h' - updated TT_MAX_SUBGLYPHS to 96 as some CJK fonts have composites with up to 80 sub-glyphs !! Thanks to Werner ====================================================================== OLD CHANGES - 14-apr-2000 - fixed a bug in the TrueType glyph loader that prevented the correct loading of some CJK glyphs in mingli.ttf - improved the standard Type 1 hinter in `src/type1' - fixed two bugs in the experimental Type 1 driver in `src/type1z' to handle the new XFree86 4.0 fonts (and a few other ones..) - the smooth renderer is now complete and supports sub-banding to render large glyphs at high speed. However, it is still located in `demos/src/ftgrays.c' and should move to the library itself in the next beta. NOTE: The smooth renderer doesn't compile in stand-alone mode anymore, but this should be fixed RSN.. - introduced convenience functions to more easily deal with glyph images, see `include/ftglyph.h' for more details, as well as the new demo program named `demos/src/ftstring.c' that demonstrates its use - implemented FT_LOAD_NO_RECURSE in both the TrueType and Type 1 drivers (this is required by the auto-hinter to improve its results). - changed the raster interface, in order to allow client applications to provide their own span-drawing callbacks. However, only the smooth renderer supports this. See `FT_Raster_Params' in the file `include/ftimage.h'. - fixed a small bug in FT_MulFix that caused incorrect transform computation! - Note: The tutorial is out-of-date. ====================================================================== OLD CHANGES - 12-mar-2000 - changed the layout of configuration files : now, all ANSI configuration files are located in `freetype2/config'. System-specific over-rides can be placed in `freetype2/config/<system>'. - moved all configuration macros to `config/ftoption.h' - improvements in the Type 1 driver with AFM support - changed the fields in the FT_Outline structure : the old `flags' array is re-named `tags', while all ancient flags are encoded into a single unsigned int named `flags'. - introduced new flags in FT_Outline.flags (see ft_outline_.... enums in `ftimage.h'). - changed outline functions to `FT_Outline_<action>' syntax - added a smooth anti-alias renderer to the demonstration programs - added Mac graphics driver (thanks Just) - FT_Open_Face changed in order to received a pointer to a FT_Open_Args descriptor.. - various cleanups, a few more API functions implemented (see FT_Attach_File) - updated some docs ====================================================================== OLD CHANGES - 22-feb-2000 - introduced the `psnames' module. It is used to: o convert a Postscript glyph name into the equivalent Unicode character code (used by the Type 1 driver(s) to synthesize on the fly a Unicode charmap). o provide an interface to retrieve the Postscript names of the Macintosh, Adobe Standard & Adobe Expert character codes. (the Macintosh names are used by the SFNT-module postscript names support routines, while the other two tables are used by the Type 1 driver(s)). - introduced the `type1z' alternate Type 1 driver. This is a (still experimental) driver for the Type 1 format that will ultimately replace the one in `src/type1'. It uses pattern matching to load data from the font, instead of a finite state analyzer. It works much better than the `old' driver with `broken' fonts. It is also much smaller (under 15 Kb). - the Type 1 drivers (both in `src/type1' and `src/type1z') are nearly complete. They both provide automatic Unicode charmap synthesis through the `psnames' module. No re-encoding vector is needed. (note that they still leak memory due to some code missing, and I'm getting lazy). Trivial AFM support has been added to read kerning information but wasn't exactly tested as it should ;-) - The TrueType glyph loader has been seriously rewritten (see the file `src/truetype/ttgload.c'. It is now much, much simpler as well as easier to read, maintain and understand :-) Preliminary versions introduced a memory leak that has been reported by Jack Davis, and is now fixed.. - introduced the new `ft_glyph_format_plotter', used to represent stroked outlines like Windows `Vector' fonts, and certain Type 1 fonts like `Hershey'. The corresponding raster will be written soon. - FT_New_Memory_Face is gone. Likewise, FT_Open_Face has a new interface that uses a structure to describe the input stream, the driver (if required), etc.. TODO - Write FT_Get_Glyph_Bitmap and FT_Load_Glyph_Bitmap - Add a function like FT_Load_Character(face, char_code, load_flags) that would really embed a call to FT_Get_Char_Index then FT_Load_Glyph to ease developer's work. - Update the tutorial! - consider adding support for Multiple Master fonts in the Type 1 drivers. - Test the AFM routines of the Type 1 drivers to check that kerning information is returned correctly. - write a decent auto-gridding component !! We need this to release FreeType 2.0 gold ! less urgent needs: - add a CFF/Type2 driver - add a BDF driver - add a FNT/PCF/HBF driver - add a Speedo driver from the X11 sources ====================================================================== OLDER CHANGES - 27-jan-2000 - updated the `sfnt' module interface to allow several SFNT-based drivers to co-exist peacefully - updated the `T1_Face' type to better separate Postscript font content from the rest of the FT_Face structure. Might be used later by the CFF/Type2 driver.. - added an experimental replacement Type 1 driver featuring advanced (and speedy) pattern matching to retrieve the data from postscript fonts. - very minor changes in the implementation of FT_Set_Char_Size and FT_Set_Pixel_Sizes (they now implement default to lighten the font driver's code). ====================================================================== OLD MESSAGE This file summarizes the changes that occurred since the last `beta' of FreeType 2. Because the list is important, it has been divided into separate sections: Table Of Contents: I High-Level Interface (easier !) II Directory Structure III Glyph Image Formats IV Build System V Portability VI Font Drivers ---------------------------------------------------------------------- High-Level Interface: The high-level API has been considerably simplified. Here is how: - resource objects have disappeared. this means that face objects can now be created with a single function call (see FT_New_Face and FT_Open_Face) - when calling either FT_New_Face & FT_Open_Face, a size object and a glyph slot object are automatically created for the face, and can be accessed through `face->glyph' and `face->size' if one really needs to. In most cases, there's no need to call FT_New_Size or FT_New_Glyph. - similarly, FT_Load_Glyph now only takes a `face' argument (instead of a glyph slot and a size). Also, its `result' parameter is gone, as the glyph image type is returned in the field `face->glyph.format' - the list of available charmaps is directly accessible through `face->charmaps', counting `face->num_charmaps' elements. Each charmap has an 'encoding' field which specifies which known encoding it deals with. Valid values are, for example: ft_encoding_unicode (for ASCII, Latin-1 and Unicode) ft_encoding_apple_roman ft_encoding_sjis ft_encoding_adobe_standard ft_encoding_adobe_expert other values may be added in the future. Each charmap still holds its `platform_id' and `encoding_id' values in case the encoding is too exotic for the current library ---------------------------------------------------------------------- Directory Structure: Should seem obvious to most of you: freetype/ config/ -- configuration sub-makefiles ansi/ unix/ -- platform-specific configuration files win32/ os2/ msdos/ include/ -- public header files, those to be included directly by client apps src/ -- sources of the library base/ -- the base layer sfnt/ -- the sfnt `driver' (see the drivers section below) truetype/ -- the truetype driver type1/ -- the type1 driver shared/ -- some header files shared between drivers demos/ -- demos/tools docs/ -- documentation (a bit empty for now) ---------------------------------------------------------------------- Glyph Image Formats: Drivers are now able to register new glyph image formats within the library. For now, the base layer supports of course bitmaps and vector outlines, but one could imagine something different like colored bitmaps, bi-color vectors or whatever else (Metafonts anyone ??). See the file `include/ftimage.h'. Note also that the type FT_Raster_Map is gone, and is now replaced by FT_Bitmap, which should encompass all known bitmap types. Each new image format must provide at least one `raster', i.e. a module capable of transforming the glyph image into a bitmap. It's also possible to change the default raster used for a given glyph image format. The default outline scan-converter now uses 128 levels of grays by default, which tends to smooth many things. Note that the demo programs have been updated significantly in order to display these.. ---------------------------------------------------------------------- Build system: You still need GNU Make to build the library. The build system has been very seriously re-vamped in order to provide things like : - automatic host platform detection (reverting to 'config/ansi' if it is not detected, with pseudo-standard compilation flags) - the ability to compile from the Makefiles with very different and exotic compilers. Note that linking the library can be difficult for some platforms. For example, the file `config/win32/lcclib.bat' is invoked by the build system to create the `.lib' file with LCC-Win32 because its librarian has too many flaws to be invoked directly from the Makefile. Here's how it works: - the first time you type `make', the build system runs a series of sub-makefiles in order to detect your host platform. It then dumps what it found, and creates a file called `config.mk' in the current directory. This is a sub-Makefile used to define many important Make variables used to build the library. - the second time, the build system detects the `config.mk' then use it to build the library. All object files go into 'obj' by default, as well as the library file, but this can easily be changed. Note that you can run `make setup' to force another host platform detection even if a `config.mk' is present in the current directory. Another solution is simply to delete the file, then re-run make. Finally, the default compiler for all platforms is gcc (for now, this will hopefully changed in the future). You can however specify a different compiler by specifying it after the 'setup' target as in: gnumake setup lcc on Win32 to use the LCC compiler gnumake setup visualc on Win32 to use Visual C++ See the file `config/<system>/detect.mk' for a list of supported compilers for your platforms. It should be relatively easy to write new detection rules files and config.mk.. Finally, to build the demo programs, go to `demos' and launch GNU Make, it will use the `config.mk' in the top directory to build the test programs.. ---------------------------------------------------------------------- Portability: In the previous beta, a single FT_System object was used to encompass all low-level operations like thread synchronisation, memory management and i/o access. This has been greatly simplified: - thread synchronisation has been dropped, for the simple reason that the library is already re-entrant, and that if you really need two threads accessing the same FT_Library, you should really synchronize access to it yourself with a simple mutex. - memory management is performed through a very simple object called `FT_Memory', which really is a table containing a table of pointers to functions like malloc, realloc and free as well as some user data (closure). - resources have disappeared (they created more problems than they solved), and i/o management have been simplified greatly as a result. Streams are defined through FT_Stream objects, which can be either memory-based or disk-based. Note that each face has its own stream, which is closed only when the face object is destroyed. Hence, a function like TT_Flush_Face in 1.x cannot be directly supported. However, if you really need something like this, you can easily tailor your own streams to achieve the same feature at a lower level (and use FT_Open_Face instead of FT_New_Face to create the face). See the file `include/ftsystem.h' for more details, as well as the implementations found in `config/unix' and `config/ansi'. ---------------------------------------------------------------------- Font Drivers: The Font Driver interface has been modified in order to support extensions & versioning. The list of the font drivers that are statically linked to the library at compile time is managed through a new configuration file called `config/<platform>/ftmodule.h'. This file is autogenerated when invoking `make modules'. This target will parse all sub-directories of 'src', looking for a `module.mk' rules file, used to describe the driver to the build system. Hence, one should call `make modules' each time a font driver is added or removed from the `src' directory. Finally, this version provides a `pseudo-driver' in `src/sfnt'. This driver doesn't support font files directly, but provides services used by all TrueType-like font drivers. Hence, its code is shared between the TrueType & OpenType font formats, and possibly more formats to come if we're lucky.. ---------------------------------------------------------------------- Extensions support: The extensions support is inspired by the one found in 1.x. Now, each font driver has its own `extension registry', which lists which extensions are available for the font faces managed by the driver. Extension ids are now strings, rather than 4-byte tags, as this is usually more readable. Each extension has: - some data, associated to each face object - an interface (table of function pointers) An extension that is format-specific should simply register itself to the correct font driver. Here is some example code: // Registering an extensions // FT_Error FT_Init_XXXX_Extension( FT_Library library ) { FT_DriverInterface* tt_driver; driver = FT_Get_Driver( library, "truetype" ); if (!driver) return FT_Err_Unimplemented_Feature; return FT_Register_Extension( driver, &extension_class ); } // Implementing the extensions // FT_Error FT_Proceed_Extension_XXX( FT_Face face ) { FT_XXX_Extension ext; FT_XXX_Extension_Interface ext_interface; ext = FT_Get_Extension( face, "extensionid", &ext_interface ); if (!ext) return error; return ext_interface->do_it(ext); } ------------------------------------------------------------------------ Copyright (C) 2000-2022 by David Turner, Robert Wilhelm, and Werner Lemberg.

How to customize the compilation of the library =============================================== FreeType is highly customizable to fit various needs, and this document describes how it is possible to select options and components at compilation time. I. Configuration macros The file `include/freetype/config/ftoption.h' contains a list of commented configuration macros that can be toggled by developers to indicate which features should be active while building the library. These options range from debug level to availability of certain features, like native TrueType hinting through a bytecode interpreter. We invite you to read this file for more information. You can change the file's content to suit your needs, or override it with one of the techniques described below. II. Modules list If you use GNU make please edit the top-level file `modules.cfg'. It contains a list of available FreeType modules and extensions to be compiled. Change it to suit your own preferences. Be aware that certain modules depend on others, as described in the file. GNU make uses `modules.cfg' to generate `ftmodule.h' (in the object directory). If you build FreeType in a directory separate from the source files, put your customized `modules.cfg' in that directory; that way you can keep the source files `clean'. If you don't use GNU make you have to manually edit the file `include/freetype/config/ftmodule.h' (which is *not* used with if compiled with GNU make) to add or remove the drivers and components you want to compile into the library. See `INSTALL.ANY' for more information. III. System interface FreeType's default interface to the system (i.e., the parts that deal with memory management and i/o streams) is located in `src/base/ftsystem.c'. The current implementation uses standard C library calls to manage memory and to read font files. It is however possible to write custom implementations to suit specific systems. To tell the GNU Make-based build system to use a custom system interface, you have to define the environment variable FTSYS_SRC to point to the relevant implementation: on Unix: ./configure <your options> export FTSYS_SRC=foo/my_ftsystem.c make make install on Windows: make setup <compiler> set FTSYS_SRC=foo/my_ftsystem.c make IV. Overriding default configuration and module headers It is possible to override the default configuration and module headers without changing the original files. There are three ways to do that: 1. With GNU make [This is actually a combination of method 2 and 3.] Just put your custom `ftoption.h' file into the objects directory (normally `<topdir>/objs' if you build in the source tree, or the directory where you invoke configure if you build in a separate directory), which GNU make prefers over the standard location. No action is needed for `ftmodule.h' because it is generated automatically in the objects directory. 2. Using the C include path Use the C include path to ensure that your own versions of the files are used at compile time when the lines #include FT_CONFIG_OPTIONS_H #include FT_CONFIG_MODULES_H are compiled. Their default values being <freetype/config/ftoption.h> and <freetype/config/ftmodule.h>, you can do something like: custom/ config/ ftoption.h => custom options header ftmodule.h => custom modules list include/ => normal FreeType 2 include ... then change the C include path to always give the path to `custom' before the FreeType 2 `include'. 3. Redefining FT_CONFIG_OPTIONS_H and FT_CONFIG_MODULES_H Another way to do the same thing is to redefine the macros used to name the configuration headers. To do so, you need a custom `ft2build.h' whose content can be as simple as: #ifndef FT2_BUILD_MY_PLATFORM_H_ #define FT2_BUILD_MY_PLATFORM_H_ #define FT_CONFIG_OPTIONS_H <custom/my-ftoption.h> #define FT_CONFIG_MODULES_H <custom/my-ftmodule.h> #include <freetype/config/ftheader.h> #endif /* FT2_BUILD_MY_PLATFORM_H_ */ Place those files in a separate directory, e.g., custom/ ft2build.h => custom version described above my-ftoption.h => custom options header my-ftmodule.h => custom modules list header and change the C include path to ensure that `custom' is always placed before the FT2 `include' during compilation. ---------------------------------------------------------------------- Copyright (C) 2003-2022 by David Turner, Robert Wilhelm, and Werner Lemberg.

Debugging within the FreeType sources ===================================== I. Configuration macros ----------------------- There are several ways to enable debugging features in a FreeType 2 builds. This is controlled through the definition of special macros located in the file `ftoption.h'. The macros are: FT_DEBUG_LEVEL_ERROR #define this macro if you want to compile the `FT_ERROR' macro calls to print error messages during program execution. This does not stop the program. Very useful to spot invalid fonts during development and to code workarounds for them. FT_DEBUG_LEVEL_TRACE #define this macro if you want to compile both macros `FT_ERROR' and `FT_TRACE'. This also includes the variants `FT_TRACE0', `FT_TRACE1', `FT_TRACE2', ..., `FT_TRACE7'. The trace macros are used to send debugging messages when an appropriate `debug level' is configured at runtime through the `FT2_DEBUG' environment variable (more on this later). FT_DEBUG_MEMORY If this macro is #defined, the FreeType engine is linked with a small but effective debugging memory manager that tracks all allocations and frees that are performed within the font engine. When the `FT2_DEBUG_MEMORY' environment variable is defined at runtime, a call to `FT_Done_FreeType' dumps memory statistics, including the list of leaked memory blocks and optionally with the source locations where these were allocated. It is always a very good idea to define this in development builds. This works with _any_ program linked to FreeType, but requires a big deal of memory (the debugging memory manager never frees the blocks to the heap in order to detect double frees). When `FT2_DEBUG_MEMORY' isn't defined at runtime, the debugging memory manager is ignored, and performance is unaffected. FT_DEBUG_LOGGING #define this macro for enhanced logging support; it automatically sets `FT_DEBUG_LEVEL_TRACE' and `FT_DEBUG_LEVEL_ERROR'. If defined, `FT_TRACE' and `FT_ERROR' can send tracing and debugging messages to a file. The location of the log file has to be set with the `FT_LOGGING_FILE' environment variable (more on this later). The main enhancements are the possibility of logging the time and the name of the `FT_COMPONENT' macro together with the affected `FT_TRACE' or `FT_ERROR' calls. See below how to activate this in the `FT2_DEBUG' environment variable. II. Debugging macros -------------------- Several macros can be used within the FreeType sources to help debugging its code: 1. FT_ERROR(( ... )) This macro is used to send debug messages that indicate relatively serious errors (like broken font files) without stopping the execution of the running program. Its code is compiled only when either `FT_DEBUG_LEVEL_ERROR' or `FT_DEBUG_LEVEL_TRACE' are defined in `ftoption.h'. Note that you have to use a printf-like signature, but with double parentheses, like in FT_ERROR(( "your %s is not %s\n", "foo", "bar" )); 2. FT_ASSERT( condition ) This macro is used to check strong assertions at runtime. If its condition isn't TRUE, the program aborts with a panic message. Its code is compiled when either `FT_DEBUG_LEVEL_ERROR' or `FT_DEBUG_LEVEL_TRACE' are defined. You don't need double parentheses here. Example: FT_ASSERT( ptr != NULL ); 3. FT_TRACE( level, (message...) ) The `FT_TRACE' macro is used to send general-purpose debugging messages during program execution. This macro uses an *implicit* macro named `FT_COMPONENT', which names the current FreeType component being run. The developer should always define `FT_COMPONENT' as appropriate, for example as in #undef FT_COMPONENT #define FT_COMPONENT io The value of the `FT_COMPONENT' macro is one of the component names defined in the internal file `internal/fttrace.h'. If you modify the FreeType source code and insert a new `FT_COMPONENT' macro, you must register it in `fttrace.h'. If you insert or remove many trace macros, you can test for undefined or unused trace macros with the script `src/tools/chktrcmp.py'. Each such component is assigned a `debug level', ranging from value 0 to 7, through the use of the `FT2_DEBUG' environment variable (described below) when a program linked with FreeType starts. When `FT_TRACE' is called, its level is compared to the one of the corresponding component. Messages with trace levels *higher* than the corresponding component level are filtered out and never printed. This means that trace messages with level 0 are always printed, those with level 2 are only printed when the component level is *at least* 2, etc. The second parameter to `FT_TRACE' must contain parentheses and corresponds to a printf-like call, as in FT_TRACE( 2, ( "your %s is not %s\n", "foo", "bar" ) ) The shortcut macros `FT_TRACE0', `FT_TRACE1', `FT_TRACE2', ..., `FT_TRACE7' can be used with constant level indices, and are much cleaner to use, as in FT_TRACE2(( "your %s is not %s\n", "foo", "bar" )); III. Environment variables -------------------------- The following environment variables control debugging output and behaviour of FreeType at runtime. FT2_DEBUG This variable is only used when FreeType is built with `FT_DEBUG_LEVEL_TRACE' defined. It contains a list of component level definitions, following this format: component1:level1 component2:level2 component3:level3 ... where `componentX' is the name of a tracing component, as defined in `fttrace.h'. `levelX' is the corresponding level to use at runtime. `any' is a special component name that is interpreted as `any/all components'. For example, the following definitions set FT2_DEBUG=any:2 memory:5 io:4 (on Windows) export FT2_DEBUG="any:2 memory:5 io:4" (on Linux with bash) both stipulate that all components should have level 2, except for the memory and io components, which are set to the trace levels 5 and 4, respectively. If `FT_DEBUG_LOGGING' is defined, two more options are available. * -v: Print also the name of FreeType's component from which the current log is produced, together with the tracing level. * -t: Print also the time. Here are some examples how the output might look like. FT2_DEBUG="any:7 memory:5 -vt" => [20:32:02:44969 ttload:2] table directory loaded FT2_DEBUG="any:7 memory:5 -t" => [20:32:02:44969] table directory loaded FT2_DEBUG="any:7 memory:5 -v" => [ttload:2] table directory loaded FT_LOGGING_FILE This variable is only used if FreeType is built with the `FT_DEBUG_LOGGING' macro defined. It contains the path to the file where the user wants to put his log file. If it is not set, FreeType uses stderr. Examples: On UNIX-like systems with bash: export FT_LOGGING_FILE="/tmp/freetype2.log" On Windows: set FT_LOGGING_FILE=C:\Users\AppData\Local\Temp\freetype2.log FT2_DEBUG_MEMORY This environment variable, when defined, tells FreeType to use a debugging memory manager that tracks leaking memory blocks as well as other common errors like double frees. It is also capable of reporting _where_ the leaking blocks were allocated, which considerably saves time when debugging new additions to the library. This code is only compiled when FreeType is built with the `FT_DEBUG_MEMORY' macro #defined in `ftoption.h' though, it is ignored in other builds. FT2_ALLOC_TOTAL_MAX This variable is ignored if `FT2_DEBUG_MEMORY' is not defined. It allows you to specify a maximum heap size for all memory allocations performed by FreeType. This is very useful to test the robustness of the font engine and programs that use it in tight memory conditions. If it is undefined, or if its value is not strictly positive, no allocation bounds are checked at runtime. FT2_ALLOC_COUNT_MAX This variable is ignored if `FT2_DEBUG_MEMORY' is not defined. It allows you to specify a maximum number of memory allocations performed by FreeType before returning the error `FT_Err_Out_Of_Memory'. This is useful for debugging and testing the engine's robustness. If it is undefined, or if its value is not strictly positive, no allocation bounds are checked at runtime. FT2_KEEP_ALIVE This variable is ignored if `FT2_DEBUG_MEMORY' is not defined. `Keep alive' means that freed blocks aren't released to the heap. This is useful to detect double-frees or weird heap corruption, reporting the source code location of the original allocation and deallocation in case of a problem. It uses large amounts of memory, however. If it is undefined, or if its value is not strictly positive, freed blocks are released at runtime. IV. Additional Capabilities with `FT_DEBUG_LOGGING' --------------------------------------------------- If `FT_DEBUG_LOGGING' is defined, four APIs are available to provide additional debugging support. Use #include <freetype/ftlogging.h> to access them. FT_Trace_Set_Level( const char* level ) By default, FreeType uses the tracing levels set in the `FT2_DEBUG' environment variable. Use this function to override the value with `level'. Use value `NULL' to disable tracing. FT_Trace_Set_Default_Level(): Reset the tracing levels to the default value, i.e., the value of the `FT2_DEBUG' environment variable or no tracing if not set. FT_Set_Log_Handler( ft_custom_log_handler handler ): Use `handler' as a custom handler for formatting tracing and error messages. The `ft_custom_log_handler' typedef has the following prototype. void (*ft_custom_log_handler)( const char* ft_component, const char* fmt, va_list args ); `ft_component' is the current component like `ttload', `fmt' is the first argument of `FT_TRACE' or `FT_ERROR', and `args' holds the remaining arguments. FT_Set_Default_Log_Handler(): Reset the log handler to the default version. ------------------------------------------------------------------------ Copyright (C) 2002-2022 by David Turner, Robert Wilhelm, and Werner Lemberg.

Introduction ------------ Documentation is an extremely important part of any project, and it helps a lot if it uses consistent syntax and layout. The documentation for the FreeType library is maintained in header files in the `include/` directory in the form of code comments. These comments are extracted and organized by 'docwriter' (previously 'docmaker'). The generated docs can be viewed in the `docs/reference/site/` directory after running `make refdoc`. Documentation comments follow a specific structure and format as described below. Documentation Structure ----------------------- The documentation is divided into multiple chapters, which contain sections relevant to it. The chapter details and sections contained in them are listed in `include/freetype/ftchapters.h`. Any unlisted section is added to the 'Miscellaneous' chapter. Sections may contain sub-sections which consist of properties, enumerations, and other data types. Comment Blocks -------------- Documentation blocks follow a specific format: /***************************** (should end on column 77) * * (1 asterisk, 1 space, then content) * */ (end of block) To make 'docwriter' recognize a comment block, there must be at least two asterisks in the first line. As a consequence, you should change the second asterisk to something else if you want to prevent a comment block being handled by 'docwriter' (for example, change `/****/` to `/*#**/`). Markup Tags ----------- Markup tags are used to indicate what comes next. The syntax for a tag is: @foo: An `@`, followed by the tag, and then `:`. Reserved Tags ------------- There are some keywords that have a special meaning to docwriter. As a convention, all keywords are written in lowercase. * `chapter`: Defines a chapter. Usually the title with underscores. * `sections`: List of sections in the chapter, in order. * `section`: Defines the start or continuation of a section. * `title`: Title for a chapter or section. May contain spaces. * `abstract`: The abstract for a section, visible in the Table of Contents (TOC). * `description`: Detailed description of a tag (except chapters), shown as synopsis. * `values`: A list of 'values' for the tag. These values are used for cross-referencing. Other Tags ---------- Except the ones given above, any other tags will be added as a part of a subsection. All tags are lowercase by convention. Public Header Definitions ------------------------- The public headers for FreeType have their names defined in `include/freetype/config/ftheader.h`. Any new public header file must be defined in this file, in the following format: #define FT_NEWNAME_H <freetype/newname.h> Where `newname` is the name of the header file. This macro is combined with the file location of a sub-section and printed with the object. Note on code blocks captured after comments ------------------------------------------- All non-documentation lines after a documentation comment block are captured to be displayed as the code for the sub-section. To stop collection, a line with `/* */` should be added. General Formatting Conventions ------------------------------ * Use two spaces after a full stop ending a sentence. * Use appropriate uppercasing in titles. Refer https://english.stackexchange.com/a/34 for more information. * Do not add trailing parentheses when citing a C function. Markdown Usage -------------- All tags, except the ones that define the name and title for a block support markdown in them. Docwriter uses a markdown parser that follows rules given in John Gruber's markdown guide: https://daringfireball.net/projects/markdown/syntax with a few exceptions and extensions, detailed below. This may also be referred to as the **FreeType Flavored Markdown**. Headers ------- Markdown headers should not be used directly, because these are added based on section titles, sub-section names, and tags. However, if a header needs to be added, note the following correspondence to HTML tags: * Section title on top of the page is `H1`. * Sub-section titles are `H2`. * Parts of sub-sections are `H4`. * Any header added will be visible in the Table of Contents (TOC) of the page. Emphasis -------- * Use `_underscores_` for italics. * Use `**double asterisks**` for bold. Although the other notations (double underscore for bold, single asterisk for italics) are supported, it is recommended to use the above for consistency. Note that there may be cases where having two asterisks or underscores in a line may lead to text being picked up as italics or bold. Although unintentional, this is correct markdown behavior. For inline code, wrap the sequence with backticks (see below). This renders symbols correctly without modifications. If a symbol is absolutely required outside of an inline code block or code sequence, escape it with a backslash (like `\*` or `\_`). Lists ----- Unordered lists can be created with asterisks: * Unordered list items can use asterisks. * Another list item. Ordered lists start with numbers: 1. This is an ordered list item. 2. Brackets after numbers won't work. To continue a list over multiple paragraphs, indent them with at least four spaces. For example: 1. Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Aliquam hendrerit mi posuere lectus. Vestibulum enim wisi, viverra nec, fringilla in, laoreet vitae, risus. Donec sit amet nisl. Aliquam semper ipsum sit amet velit. Suspendisse id sem consectetuer libero luctus adipiscing. 2. This is the second list item. This paragraph is not a part of the list. More information on lists in markdown is available at https://daringfireball.net/projects/markdown/syntax#list Cross-references ---------------- Other sub-sections can be linked with the `@` symbol: @description: While FreeType's CFF driver doesn't expose API functions by itself, it is possible to control its behaviour with @FT_Property_Set and @FT_Property_Get. If a field in the `values` table of another sub-section is linked, the link leads to its parent sub-section. Links and Images ---------------- All URLs are converted to links in the HTML documentation. Markdown syntax for links and images are fully supported. Inline Code ----------- To indicate a span of code, wrap it with backtick quotes (`` ` ``): Use the `printf()` function. Cross-references, markdown, and html styling do not work in inline code sequences. Code and Syntax Highlighting ---------------------------- Blocks of code are fenced by lines with three back-ticks `` ``` `` followed by the language name, if any (used for syntax highlighting), as demonstrated in the following example. ```c x = y + z; if ( zookoo == 2 ) { foobar(); } ``` Note that the indentation of the opening line and the closing line must be exactly the same. The code sequence itself should have a larger indentation than the surrounding back-ticks. Like inline code, markdown and html styling is *not* supported inside code blocks. Tables ------ Tables are used to list values, input, and other fields. The FreeType Flavored Markdown adopts a simple approach to tables with two columns, or field definition tables. Field definition names may contain alphanumeric, underscore, and the `.` characters. This is followed by `::`. The following lines are the second column of the table. A field definition ends with the start of another field definition, or a markup tag. @Input: pathname :: A path to the font file. face_index :: See @FT_Open_Face for a detailed description of this parameter. Non-breaking Space ------------------ A tilde can be used to create a non-breaking space. The example The encoding value~0 is reserved. is converted to The encoding value 0 is reserved. ---------------------------------------------------------------------- Copyright (C) 2018-2022 by Nikhil Ramakrishnan, David Turner, Robert Wilhelm, and Werner Lemberg.

GNU GENERAL PUBLIC LICENSE Version 2, June 1991 Copyright (C) 1989, 1991 Free Software Foundation, Inc. 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Library General Public License instead.) You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow. GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. 10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. <one line to give the program's name and a brief idea of what it does.> Copyright (C) <year> <name of author> This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with this program; if not, write to the Free Software Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA Also add information on how to contact you by electronic and paper mail. If the program is interactive, make it output a short notice like this when it starts in an interactive mode: Gnomovision version 69, Copyright (C) year name of author Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details. The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, the commands you use may be called something other than `show w' and `show c'; they could even be mouse-clicks or menu items--whatever suits your program. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary. Here is a sample; alter the names: Yoyodyne, Inc., hereby disclaims all copyright interest in the program `Gnomovision' (which makes passes at compilers) written by James Hacker. <signature of Ty Coon>, 1 April 1989 Ty Coon, President of Vice This General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library. If this is what you want to do, use the GNU Library General Public License instead of this License.

There are several ways to build the FreeType library, depending on your system and the level of customization you need. Here is a short overview of the documentation available: I. Prerequisites and dependencies ================================= FreeType is a low level C library that only depends on the standard C library with very few platform-dependent optimizations utilized at build time. Any C99-compliant compiler should be able to compile FreeType. System libraries, such as zlib, Gzip, bzip2, Brotli, and libpng, might be used to handle compressed fonts or decode embedded PNG glyphs. FreeType auto-configuration scripts should be able to detect the prerequisites if the necessary headers are available at the default locations. Otherwise, modify `include/freetype/config/ftoption.h` to control how the FreeType library gets built. Normally, you don't need to change anything. Applications have very limited control over FreeType's behaviour at run-time; look at the documentation of function `FT_Property_Set`. II. Normal installation and upgrades ==================================== 1. Unix and Unix-like systems This also includes MacOS, Cygwin, MinGW + MSYS, Mingw-w64 + MSYS2, and possibly other, similar environments. Please read `INSTALL.UNIX` to install or upgrade FreeType 2 on a Unix system. Note that you *need* GNU Make for automatic compilation, since other make tools won't work (this includes BSD Make). GNU Make VERSION 3.81 OR NEWER IS NEEDED! 2. Other systems using GNU Make On some non-Unix platforms, it is possible to build the library using only the GNU Make utility. Note that *NO OTHER MAKE TOOL WILL WORK*[1]! This methods supports several compilers on Windows, OS/2, and BeOS, including MinGW* (without MSYS*), Visual C++, Borland C++, and more. Instructions are provided in the file `INSTALL.GNU`. 3. Other build tools and platforms. A few other tools can be used to build FreeType. You can find the corresponding instruction files in the FreeType root folder or the builds/ sub-folder. CMake :: see `CMakeLists.txt` for more information Meson :: see `meson.build` for more information MSBuild :: see `builds/windows/vc2010/freetype.vcxproj` MMS :: see `vms_make.com` and `docs/INSTALL.VMS` 4. With an IDE Project File (e.g., for Visual Studio or CodeWarrior) We provide a small number of 'project files' for various IDEs to automatically build the library as well. Note that these files are not actively supported by FreeType developers, they can break or become obsolete. To find them, have a look at the content of the `builds/<system>` directory, where <system> stands for your OS or environment. 5. From you own IDE, or own Makefiles If you want to create your own project file, follow the instructions given in the `INSTALL.ANY` document of this directory. III. Custom builds of the library ================================= Customizing the compilation of FreeType is easy, and allows you to select only the components of the font engine that you really need. For more details read the file `CUSTOMIZE`. ---------------------------------------------------------------------- [1] make++, a make tool written in Perl, has sufficient support of GNU make extensions to build FreeType. See https://makepp.sourceforge.net for more information; you need version 2.0 or newer, and you must pass option `--norc-substitution`. ---------------------------------------------------------------------- Copyright (C) 2000-2022 by David Turner, Robert Wilhelm, and Werner Lemberg. This file is part of the FreeType project, and may only be used, modified, and distributed under the terms of the FreeType project license, LICENSE.TXT.

Instructions on how to build FreeType with your own build tool ============================================================== See the file `CUSTOMIZE' to learn how to customize FreeType to specific environments. I. Standard procedure --------------------- * If you use macro names for FreeType header files (while mandatory in earlier versions, this is now optional since FreeType version 2.6.1) it is necessary to disable pre-compiled headers. This is very important for Visual C++, because lines like #include FT_FREETYPE_H are not correctly supported by this compiler while being ISO C compliant! * You need to add the directory `include' to your include path when compiling the library. * FreeType 2 is made of several components; each of them is located in a subdirectory of `freetype/src'. For example, `freetype/src/truetype/' contains the TrueType font driver. * DO NOT COMPILE ALL C FILES! Rather, compile the following ones. -- base components (required) src/base/ftsystem.c src/base/ftinit.c src/base/ftdebug.c src/base/ftbase.c src/base/ftbbox.c -- recommended, see <ftbbox.h> src/base/ftglyph.c -- recommended, see <ftglyph.h> src/base/ftbdf.c -- optional, see <ftbdf.h> src/base/ftbitmap.c -- optional, see <ftbitmap.h> src/base/ftcid.c -- optional, see <ftcid.h> src/base/ftfstype.c -- optional src/base/ftgasp.c -- optional, see <ftgasp.h> src/base/ftgxval.c -- optional, see <ftgxval.h> src/base/ftmm.c -- optional, see <ftmm.h> src/base/ftotval.c -- optional, see <ftotval.h> src/base/ftpatent.c -- optional src/base/ftpfr.c -- optional, see <ftpfr.h> src/base/ftstroke.c -- optional, see <ftstroke.h> src/base/ftsynth.c -- optional, see <ftsynth.h> src/base/fttype1.c -- optional, see <t1tables.h> src/base/ftwinfnt.c -- optional, see <ftwinfnt.h> src/base/ftmac.c -- only on the Macintosh -- font drivers (optional; at least one is needed) src/bdf/bdf.c -- BDF font driver src/cff/cff.c -- CFF/OpenType font driver src/cid/type1cid.c -- Type 1 CID-keyed font driver src/pcf/pcf.c -- PCF font driver src/pfr/pfr.c -- PFR/TrueDoc font driver src/sfnt/sfnt.c -- SFNT files support (TrueType & OpenType) src/truetype/truetype.c -- TrueType font driver src/type1/type1.c -- Type 1 font driver src/type42/type42.c -- Type 42 font driver src/winfonts/winfnt.c -- Windows FONT / FNT font driver -- rasterizers (optional; at least one is needed for vector formats) src/raster/raster.c -- monochrome rasterizer src/sdf/sdf.c -- Signed Distance Field driver src/smooth/smooth.c -- anti-aliasing rasterizer -- auxiliary modules (optional) src/autofit/autofit.c -- auto hinting module src/cache/ftcache.c -- cache sub-system (in beta) src/gzip/ftgzip.c -- support for compressed fonts (.gz) src/lzw/ftlzw.c -- support for compressed fonts (.Z) src/bzip2/ftbzip2.c -- support for compressed fonts (.bz2) src/gxvalid/gxvalid.c -- TrueTypeGX/AAT table validation src/otvalid/otvalid.c -- OpenType table validation src/psaux/psaux.c -- PostScript Type 1 parsing src/pshinter/pshinter.c -- PS hinting module src/psnames/psnames.c -- PostScript glyph names support Notes: `ftcache.c' needs `ftglyph.c' `ftfstype.c' needs `fttype1.c' `ftglyph.c' needs `ftbitmap.c' `ftstroke.c' needs `ftglyph.c' `ftsynth.c' needs `ftbitmap.c' `cff.c' needs `sfnt.c', `pshinter.c', and `psnames.c' `truetype.c' needs `sfnt.c' and `psnames.c' `type1.c' needs `psaux.c' `pshinter.c', and `psnames.c' `type1cid.c' needs `psaux.c', `pshinter.c', and `psnames.c' `type42.c' needs `truetype.c' Please consult the central `include/freetype/config/ftoption.h' configuration file for details on additional libraries necessary for some optional features. Read the file `CUSTOMIZE' in case you want to compile only a subset of the drivers, renderers, and optional modules; a detailed description of the various base extension is given in the top-level file `modules.cfg'. You are done. In case of problems, see the archives of the FreeType development mailing list. II. Support for flat-directory compilation ------------------------------------------ It is possible to put all FreeType 2 source files into a single directory, with the *exception* of the `include' hierarchy. 1. Copy all files in current directory cp freetype/src/base/*.[hc] . cp freetype/src/raster1/*.[hc] . cp freetype/src/smooth/*.[hc] . etc. 2. Compile sources cc -c -Iinclude -DFT2_BUILD_LIBRARY ftsystem.c cc -c -Iinclude -DFT2_BUILD_LIBRARY ftinit.c cc -c -Iinclude -DFT2_BUILD_LIBRARY ftdebug.c cc -c -Iinclude -DFT2_BUILD_LIBRARY ftbase.c etc. You don't need to define the FT_FLAT_COMPILATION macro (as this was required in previous releases of FreeType 2). ---------------------------------------------------------------------- Copyright (C) 2003-2022 by David Turner, Robert Wilhelm, and Werner Lemberg.

This document contains instructions on how to cross-build the FreeType library on Unix systems, for example, building binaries for Linux/MIPS on FreeBSD/i386. Before reading this document, please consult the file `INSTALL.UNIX' for required tools and the basic self-building procedure. 1. Required Tools ----------------- For self-building the FreeType library on a Unix system, GNU Make 3.81 or newer is required. `INSTALL.UNIX' contains hints how to check the installed `make'. The GNU C compiler to cross-build the target system is required. Currently, using a non-GNU cross compiler is untested. The cross compiler is expected to be installed with a system prefix. For example, if your building system is FreeBSD/i386 and the target system is Linux/MIPS, the cross compiler should be installed with the name `mips-ip22-linuxelf-gcc'. A C compiler for a self-build is required also, to build a tool (`apinames') that is executed during the build procedure. Non-GNU self compilers are acceptable, but such a setup is untested. 2. Configuration ---------------- 2.1. Building and target system To configure a cross-build, the options `--host=<system>' and `--build=<system>' must be passed to the `configure' script. For example, if your build system is FreeBSD/i386 and the target system is Linux/MIPS, say ./configure \ --build=i386-unknown-freebsd \ --host=mips-ip22-linuxelf \ [other options] It should be noted that `--host=<system>' specifies the system where the built binaries will be executed, not the system where the build actually happens. Older versions of GNU autoconf use the option pair `--host=' and `--target='. This is broken and doesn't work. Similarly, an explicit CC specification like env CC=mips-ip22-linux-gcc ./configure # BAD or env CC=/usr/local/mips-ip22-linux/bin/gcc ./configure # BAD doesn't work either; such a configuration confuses the `configure' script while trying to find the cross and native C compilers. 2.2. The prefix to install FreeType2 Setting `--prefix=<prefix>' properly is important. The prefix to install FreeType2 is written into the `freetype-config' script and `freetype2.pc' configuration file. If the built FreeType 2 library is used as a part of the cross-building system, the prefix is expected to be different from the self-building system. For example, a configuration with `--prefix=/usr/local' installs binaries into the system-wide `/usr/local' directory, which then can't be executed due to the incorrect architecture. This causes confusion in configuration of all applications that use FreeType2. Instead, use a prefix to install the cross-build into a separate system tree, for example, `--prefix=/usr/local/mips-ip22-linux/'. On the other hand, if the built FreeType 2 library is used as a part of the target system, the prefix to install should reflect the file system structure of the target system. 2.3. Library dependencies FreeType normally depends on external libraries like `libpng' or `libharfbuzz'. The easiest case is to deactivate all such dependencies using the `--without-XXX' configuration options. However, if you want to use those libraries, you should ensure that they are available both on the target system and as (cross-compiled) libraries on the build system. FreeType uses `pkg-config' to find most of the libraries; the other libraries it links to are expected in the standard system directories. Since the default pkg-config's meta-information files (like `harfbuzz.pc') of the build platform don't work, use one of the two possible solutions below. o Use pkg-config's meta-information files that are adjusted to cross-compile and cross-link with the target platform's libraries. Make sure those files are found before the build system's default files. Example: ./configure \ --build=i386-unknown-freebsd \ --host=mips-ip22-linuxelf \ PKG_CONFIG_LIBDIR="/usr/local/mips-ip22-linux/lib/pkgconfig" \ [other options] See the manpage of `pkg-config' for more details. o Set variables like LIBPNG_LIBS as additional options to the `configure' script, overriding the values `pkg-config' would provide. `configure --help' shows the available environment variables. Example: ./configure \ --build=i386-unknown-freebsd \ --host=mips-ip22-linuxelf \ LIBPNG_CFLAGS="-I/usr/local/mips-ip22-linux/include" \ LIBPNG_LIBS="-L/usr/local/mips-ip22-linux/lib -lpng12" \ [other options] 3. Building command ------------------- If the configuration finishes successfully, invoking GNU make builds FreeType2. Just say make or gmake depending on the name the GNU make binary actually has. 4. Installation --------------- Saying make install as usual to install FreeType2 into the directory tree specified by the argument of the `--prefix' option. As noted in section 2.2, FreeType2 is sometimes configured to be installed into the system directory of the target system, and should not be installed in the cross-building system. In such cases, the make variable `DESTDIR' is useful to change the root directory in the installation. For example, after make DESTDIR=/mnt/target_system_root/ install the built FreeType2 library files are installed into the directory `/mnt/target_system_root/<prefix_in_configure>/lib'. 5. TODO ------- Cross building between Cygwin (or MSys) and Unix must be tested. ---------------------------------------------------------------------- Copyright (C) 2006-2022 by suzuki toshiya, David Turner, Robert Wilhelm, and Werner Lemberg.

This document contains instructions how to build the FreeType library on non-Unix systems with the help of GNU Make. Note that if you are running Cygwin or MinGW/MSYS in Windows, you should follow the instructions in the file `INSTALL.UNIX' instead. FreeType 2 includes a powerful and flexible build system that allows you to easily compile it on a great variety of platforms from the command line. To do so, just follow these simple instructions. 1. Install GNU Make ------------------- The FreeType 2 build system relies on many features special to GNU Make. NEARLY ALL OTHER MAKE TOOLS FAIL, INCLUDING `BSD MAKE', SO REALLY INSTALL A RECENT VERSION OF GNU MAKE ON YOUR SYSTEM! Note that make++, a make tool written in Perl, supports enough features of GNU make to compile FreeType. See https://makepp.sourceforge.net for more information; you need version 2.0 or newer, and you must pass option `--norc-substitution'. Make sure that you are invoking GNU Make from the command line, by typing something like: make -v to display its version number. VERSION 3.81 OR NEWER IS NEEDED! 2. Invoke `make' ---------------- Go to the root directory of FreeType 2, then simply invoke GNU Make from the command line. This will launch the FreeType 2 host platform detection routines. A summary will be displayed, for example, on Win32. ============================================================== FreeType build system -- automatic system detection The following settings are used: platform windows compiler gcc configuration directory .\builds\windows configuration rules .\builds\windows\w32-gcc.mk If this does not correspond to your system or settings please remove the file 'config.mk' from this directory then read the INSTALL file for help. Otherwise, simply type 'make' again to build the library or 'make refdoc' to build the API reference (the latter needs Python >= 3.5). ============================================================= If the detected settings correspond to your platform and compiler, skip to step 5. Note that if your platform is completely alien to the build system, the detected platform will be `ansi'. 3. Configure the build system for a different compiler ------------------------------------------------------ If the build system correctly detected your platform, but you want to use a different compiler than the one specified in the summary (for most platforms, gcc is the default compiler), invoke GNU Make with make setup <compiler> Examples: to use Visual C++ on Win32, type: `make setup visualc' to use Borland C++ on Win32, type `make setup bcc32' to use Watcom C++ on Win32, type `make setup watcom' to use Intel C++ on Win32, type `make setup intelc' to use LCC-Win32 on Win32, type: `make setup lcc' to use Watcom C++ on OS/2, type `make setup watcom' to use VisualAge C++ on OS/2, type `make setup visualage' The <compiler> name to use is platform-dependent. The list of available compilers for your system is available in the file `builds/<system>/detect.mk'. If you are satisfied by the new configuration summary, skip to step 5. 3a. Use clang instead of gcc ---------------------------- The `clang' compiler can use FreeType's setup for `gcc'; it is sufficient to set the `CC' variable, for example make CC=clang 3b. Compiling with a C++ compiler --------------------------------- FreeType can be built with a C++ compiler, for example make CC="g++" If `clang++' should be used it is necessary to also override the `ANSIFLAGS' variable: make CC="clang++" ANSIFLAGS="" 4. Configure the build system for an unknown platform/compiler -------------------------------------------------------------- The auto-detection/setup phase of the build system copies a file to the current directory under the name `config.mk'. For example, on OS/2+gcc, it would simply copy `builds/os2/os2-gcc.mk' to `./config.mk'. If for some reason your platform isn't correctly detected, copy manually the configuration sub-makefile to `./config.mk' and go to step 5. Note that this file is a sub-Makefile used to specify Make variables for compiler and linker invocation during the build. You can easily create your own version from one of the existing configuration files, then copy it to the current directory under the name `./config.mk'. 5. Build the library -------------------- The auto-detection/setup phase should have copied a file in the current directory, called `./config.mk'. This file contains definitions of various Make variables used to invoke the compiler and linker during the build. [It has also generated a file called `ftmodule.h' in the objects directory (which is normally `<toplevel>/objs/'); please read the file `docs/CUSTOMIZE' for customization of FreeType.] To launch the build, simply invoke GNU Make again: The top Makefile will detect the configuration file and run the build with it. If you have used variables in step 3, you must use the same variables here, too. Final note The above instructions build a _statically_ linked library of the font engine in the `objs' directory. On Windows, you can build a DLL either with MinGW (within an MSYS shell, following the instructions in `INSTALL.UNIX'), or you use one of the Visual C++ project files; see the subdirectories of `builds/windows'. For everything else, you are on your own, and you might follow the instructions in `INSTALL.ANY' to create your own Makefiles. ---------------------------------------------------------------------- Copyright (C) 2003-2022 by David Turner, Robert Wilhelm, and Werner Lemberg.

Please follow the instructions in INSTALL.UNIX to install FreeType on Mac OS X. Currently FreeType2 functions based on some deprecated Carbon APIs return `FT_Err_Unimplemented_Feature' always, even if FreeType2 is configured and built on the system that deprecated Carbon APIs are available. To enable deprecated FreeType2 functions as far as possible, replace `src/base/ftmac.c' by `builds/mac/ftmac.c'. Starting with Mac OS X 10.5, gcc defaults the deployment target to 10.5. In previous versions of Mac OS X, this defaulted to 10.1. If you want your built binaries to run only on 10.5, this change does not concern you. If you want them to also run on older versions of Mac OS X, then you must either set the MACOSX_DEPLOYMENT_TARGET environment variable or pass `-mmacosx-version-min' to gcc. You should specify the oldest version of Mac OS you want the code to run on. For example, if you use Bourne shell: export MACOSX_DEPLOYMENT_TARGET=10.2 or, if you use C shell: setenv MACOSX_DEPLOYMENT_TARGET 10.2 Alternatively, you could pass `-mmacosx-version-min=10.2' to gcc. Here the number 10.2 is the lowest version that the built binaries can run on. In the above cases, the built binaries will run on Mac OS X 10.2 and later, but _not_ earlier. If you want to run on earlier, you have to set lower version, e.g., 10.0. For classic Mac OS (Mac OS 7, 8, 9) please refer to builds/mac/README.

This document contains instructions on how to build the FreeType library on Unix systems. This also works for emulations like Cygwin or MSys on Win32: 1. Ensure that you are using GNU Make ------------------------------------- The FreeType build system _exclusively_ works with GNU Make. You will not be able to compile the library with the instructions below using any other alternative (including BSD Make). Check that you have GNU make by running the command: make -v This should dump some text that begins with: GNU Make <version number> Copyright (C) <year> Free Software Foundation Inc. Note that version 3.81 or higher is *required* or the build will fail. It is also fine to have GNU Make under another name (e.g. 'gmake') if you use the MAKE variable as described below. As a special exception, 'makepp' can also be used to build FreeType 2. See the file docs/MAKEPP for details. For builds with `cmake' please check file `CMakeLists.txt'; this is a contributed file not directly supported by the FreeType team. 2. Regenerate the configure script if needed -------------------------------------------- This only applies if you are building a git snapshot or checkout, *not* if you grabbed the sources of an official release. You need to invoke the `autogen.sh' script in the top-level directory in order to create the `configure' script for your platform. Normally, this simply means typing: sh autogen.sh In case of problems, you may need to install or upgrade Automake, Autoconf or Libtool. See `README.git' in the top-level directory for more information. 3. Build and install the library -------------------------------- Say ./configure --help to see the list of possible configuration options and important environment variables. The ./configure script will detect some prerequisite system libraries (libpng, brotli, etc.) if their headers are available at the default locations. The following should work on all Unix systems where the `make' command invokes GNU Make: ./configure [options] make make install (as root) The default installation path is `/usr/local'. It can be changed with the `--prefix=<path>' option. Example: ./configure --prefix=/usr When using a different command to invoke GNU Make, use the MAKE variable. For example, if `gmake' is the command to use on your system, do something like: MAKE=gmake ./configure [options] gmake gmake install (as root) If this still doesn't work, there must be a problem with your system (e.g., you are using a very old version of GNU Make). For library identification, FreeType's `configure' script uses the `pkg-config' interface: Assuming it needs library `foo', it calls the `pkg-config' program to find information on library `foo', which in turn looks for a `foo.pc' file installed at the system. Some platforms, however, don't come with `pkg-support'; you then have to use environment variables as described by `configure --help'. Example: LIBPNG_CFLAGS="-I/path/to/libpng/include/directory" \ LIBPNG_LIBS="-L/path/to/libpng/lib/directory" \ configure ... It is possible to compile FreeType in a different directory. Assuming the FreeType source files in directory `/src/freetype' a compilation in directory `foo' works as follows: cd foo /src/freetype/configure [options] make make install 3.1 Interdependency with HarfBuzz ................................. Note that there is a chicken-and-egg problem currently since the HarfBuzz library (used by the auto-hinter to improve support of OpenType fonts) depends on FreeType, which can be solved as follows in case HarfBuzz is not yet installed on your system. 1. Call FreeType's `configure' script with option `--without-harfbuzz', then compile and install FreeType. 2. Compile and install HarfBuzz. 3. Call FreeType's `configure' script without option `--without-harfbuzz' (after executing `make distclean'), then compile and install FreeType again. ---------------------------------------------------------------------- Copyright (C) 2003-2022 by David Turner, Robert Wilhelm, and Werner Lemberg.

How to build the FreeType 2 library on VMS ----------------------------------------- It is actually very straightforward to install the FreeType 2 library. Just execute vms_make.com from the toplevel directory to build the library. This procedure currently accepts the following options: DEBUG Build the library with debug information and without optimization. lopts=<value> Options to pass to the link command e.g. lopts=/traceback ccopt=<value> Options to pass to the C compiler e.g. ccopt=/float=ieee In case you did download the demos, place them in a separate directory sharing the same top level as the directory of FreeType 2 and follow the same instructions as above for the demos from there. The build process relies on this to figure out the location of the FreeType 2 include files. To rebuild the sources it is necessary to have MMS/MMK installed on the system. The library is available in the directory [.LIB] To compile applications using FreeType 2 you have to define the logical FREETYPE pointing to the directory [.INCLUDE.FREETYPE] i.e., if the directory in which this INSTALL.VMS file is located is $disk:[freetype] then define the logical with define freetype $disk:[freetype.include.freetype] This version has been tested with Compaq C V6.2-006 on OpenVMS Alpha V7.2-1. Any problems can be reported to Jouk Jansen <joukj@hrem.stm.tudelft.nl> or Martin P.J.

As a special exception, FreeType can also be built with the 'makepp' build tool, available from https://makepp.sourceforge.net. Note, however, that you will need at least version 2.0 and pass the option --norc-substitution to have it work correctly.

This file describes various problems that have been encountered in compiling, installing and running FreeType 2. Suggestions for additions or other improvements to this file are welcome. ---------------------------------------------------------------------- Running Problems ================ * Some Type 1, Multiple Masters, and CID-keyed PostScript fonts aren't handled correctly. ----- Of course, there might be bugs in FreeType, but some fonts based on the PostScript format can't be handled indeed. The reason is that FreeType doesn't contain a full PostScript interpreter but applies pattern matching instead. In case a font doesn't follow the standard structure of the given font format, FreeType fails. A typical example is Adobe's `Optima' font family which contains extra code to switch between low and high resolution versions of the glyphs. It might be possible to patch FreeType in some situations, though. Please report failing fonts so that we investigate the problem and set up a list of such problematic fonts. * Why do identical FreeType versions render differently on different platforms? ----- Different distributions compile FreeType with different options. The developer version of a distribution's FreeType package, which is needed to compile your program against FreeType, includes the file ftoption.h. Compare each platform's copy of ftoption.h to find the differences. ---------------------------------------------------------------------- Compilation Problems ==================== * I get an `internal compilation error' (ICE) while compiling FreeType 2.2.1 with Intel C++. This has been reported for the following compiler version: Intel(R) C++ Compiler for 32-bit applications, Version 9.0 Build 20050430Z Package ID: W_CC_P_9.0.019 ----- The best solution is to update the compiler to version Intel(R) C++ Compiler for 32-bit applications, Version 9.1 Build 20060323Z Package ID: W_CC_P_9.1.022 or newer.

After saying `make refdoc' or `make refdoc-venv' the `reference/' directory contains the FreeType API reference. You need Python >= 3.5 and pip to make this target. There are two ways to generate the documentation: 1. Using `make refdoc': - Ensure `python' and `pip' are available. - Install pip package `docwriter' with `pip install --user docwriter'. - Make target with `make refdoc'. - This target can be run offline once required packages are installed. 2. Using `make refdoc-venv' (requires internet access): - Ensure `python', `pip' and Python package `virtualenv' are available. - Make target with `make refdoc-venv'. - This may or may not require internet access every time depending on pip and system caching. This also works with Jam: Just type `jam refdoc' in the main directory. Some troubleshooting tips: * Regularly run `pip install --upgrade docwriter' to check for updates which may include bug fixes. * `Docwriter' does not support Python 2. Ensure that Python >= 3.5 is installed and available as `python3'/`python'. * Ensure that `docwriter' is installed in the same Python target that `make refdoc' uses (python3/python). * If none of this works, send a mail to `freetype-devel@nongnu.org' or file an issue at `https://github.com/freetype/docwriter/issues'.

Here is a list of items that need to be addressed in FreeType 2 --------------------------------------------------------------- * Implement stem3/counter hints properly in the Postscript hinter. * Add CIDCMap support to the CID driver. * Add track kerning support to the PFR driver. * Add kerning (AFM file) support to the CID driver. Here is a list of bugs which should be handled ---------------------------------------------- Other bugs have been registered at the savannah bugzilla of FreeType. * CID driver: Handle the case where a CID font has a top-level font matrix also (see PLRM, 5.11.3, Type 0 CIDFonts). Since CID_FaceInfoRec lacks a font_matrix entry we have to directly apply it to all subfont matrices. * CID driver: Use top-level font matrix entry for setting the upem value, not the entries in the FDarray. If absent, use 1000. ------------------------------------------------------------------------ Copyright (C) 2001-2022 by David Turner, Robert Wilhelm, and Werner Lemberg.

Due to our use of `libtool' to generate and install the FreeType 2 libraries on Unix systems, as well as other historical events, it is generally very difficult to know precisely which release of the font engine is installed on a given system. This file tries to explain why and to document ways to properly detect FreeType on Unix. 1. Version and Release numbers ------------------------------ For each new public release of FreeType 2, there are generally *three* distinct `version' numbers to consider: * The official FreeType 2 release number, like 2.7.0 or 2.10.2. * The libtool (and Unix) specific version number, like 23.2.17. This is what pkg-config freetype2 --modversion or freetype-config --version returns. * The platform-specific shared object number, used for example when the library is installed as `/usr/lib/libfreetype.so.6.17.2'. The platform-specific number is, unsurprisingly, platform-specific and varies with the operating system you are using (several variants of Linux, FreeBSD, Solaris, etc.). You should thus _never_ use it, even for simple tests. The libtool-specific number does not equal the release number but is tied to it. The release number is available at *compile* time through the following macros defined in `freetype.h': - FREETYPE_MAJOR: major release number - FREETYPE_MINOR: minor release number - FREETYPE_PATCH: patch release number See below for a small autoconf fragment. The release number is also available at *runtime* through the `FT_Library_Version' API. 2. History ---------- The following table gives, for all releases since 2.5.0, the corresponding libtool number, as well as the shared object number found on _most_ systems, but not all of them: release libtool so ------------------------------- 2.12.0 24.2.18 6.18.2 2.11.1 24.1.18 6.18.1 2.11.0 24.0.18 6.18.0 2.10.4 23.4.17 6.17.4 2.10.3 23.3.17 6.17.3 2.10.2 23.2.17 6.17.2 2.10.1 23.1.17 6.17.1 2.10.0 23.0.17 6.17.0 2.9.1 22.1.16 6.16.1 2.9.0 22.0.16 6.16.0 2.8.1 21.0.15 6.15.0 2.8.0 20.0.14 6.14.0 2.7.1 19.0.13 6.13.0 2.7.0 18.6.12 6.12.6 2.6.5 18.5.12 6.12.5 2.6.4 18.4.12 6.12.4 2.6.3 18.3.12 6.12.3 2.6.2 18.2.12 6.12.2 2.6.1 18.1.12 6.12.1 2.6.0 18.0.12 6.12.0 2.5.5 17.4.11 6.11.4 2.5.4 17.3.11 6.11.3 2.5.3 17.2.11 6.11.2 2.5.2 17.1.11 6.11.1 2.5.1 17.0.11 6.11.0 2.5.0 16.2.10 6.10.2 3. Autoconf Code Fragment ------------------------- Lars Clausen contributed the following autoconf fragment to check which version of FreeType is installed on a system (now updated to use `pkg-config' instead of `freetype-config'). This one tests for a version that is at least 2.10.2; you should change it to check against other release numbers.

This file contains a list of various font formats. It gives the reference document and whether it is supported in FreeType 2. Table fields ------------ wrapper format The format used to represent the font data. In the table below it is used only if the font format differs. Possible values are SFNT binary PFB binary PS a text header, followed by binary or text data LZW compressed with either `gzip' or `compress' BZ2 compressed with `bzip2'. font format How the font is to be accessed, possibly after converting the file type and wrapper format into a generic form. Bitmap formats are `BDF', `PCF', and one form of `WINFNT'; all others are vector formats. `PS' indicates third-order, `TT' second-order Bézier curves. font type Sub-formats of the font format. `SBIT' and `MACSBIT' are bitmap formats, `MM' and `VAR' support optical axes. `CFF2' supports optical axes also. glyph access If not specified, the glyph access is `standard' to the font format. Values are `CID' for CID-keyed fonts, `SYNTHETIC' for fonts that are modified versions of other fonts by means of a transformation matrix, and `TYPE_0' for PS fonts which are to be accessed in a tree-like structure. FreeType driver The module in the FreeType library which handles the specific font format. A missing entry means that FreeType doesn't support the font format (yet). Notes ----- The SFNT container format also provides `collections' (usually having the file extension `.ttc' or `.otc'). A collection contains multiple font faces that share some tables to avoid redundancy, thus reducing the file size. In FreeType, elements of a collection can be accessed with a proper face index. Both the GX and the OpenType 1.8 variation fonts provide `named instances'. FreeType maps them to face indices (they can also be accessed with the standard MM interface). Other font formats (not using the SFNT wrapper) also provide multiple faces within one file; they are marked with an asterisk (`*') in the table below. FreeType can be configured to support Mac files (on older Mac OS versions, a `file' is stored as a data and a resource fork, this is, within two separate data chunks). If a file can't be opened as a font, FreeType then checks whether it is a resource fork, trying to extract the contained font data from either a `POST' or `sfnt' resource. Please send additions and/or corrections to wl@gnu.org or to the FreeType developer's list at freetype-devel@nongnu.org (for subscribers only).

.TH FREETYPE-CONFIG 1 "March 2022" "FreeType 2.12.0" . . .SH NAME . freetype-config \- Get information about a libfreetype installation . . .SH SYNOPSIS . .B freetype-config .RI [ options ] . . .SH DESCRIPTION . .B freetype-config returns information needed for compiling and linking programs with the FreeType library, such as linker flags and compilation parameters. . Alternatively, it can be used to query information about the FreeType library version installed on the system, such as the installation (directory path) prefix or the FreeType version number. . .PP If .BR pkg-config (1) is found in the path, .B freetype-config acts as a wrapper for .BR pkg-config . . .PP This program is part of the FreeType package. . . .SH OPTIONS . There are two types of options: output/display selection options, and path override options. . . .SS Output selection options . Only one of the output selection options should be given at each program invocation. . .TP .B \-\-prefix Return the prefix value of the installed FreeType library (the default prefix will be `/usr' in most cases for distribution-installed packages). . .TP .B \-\-exec-prefix Return the executable prefix value of the installed FreeType library (will often be the same as the prefix value). . .TP .B \-\-ftversion Return the FreeType version number, directly derived from file `freetype.h'. . .TP .B \-\-version Return the `libtool version' of the FreeType library. . .TP .B \-\-libtool Return the library name for linking with libtool. . .TP .B \-\-libs Return compiler flags for linking with the installed FreeType library. . .TP .B \-\-cflags Return compiler flags for compiling against the installed FreeType library. . .TP .B \-\-static Make command line options display flags for static linking. . .TP .B \-\-help Show help and exit. . . .SS Path override options . These affect any selected output option, except the libtool version returned by .BR \-\-version . . .TP .BI \-\-prefix= PREFIX Override .B \-\-prefix value with .IR PREFIX . . This also sets .BI \-\-exec-prefix= PREFIX if option .B \-\-exec-prefix is not explicitly given. . .TP .BI \-\-exec-prefix= EPREFIX Override .B \-\-exec-prefix value with .IR EPREFIX . . . .SH BUGS In case the libraries FreeType links to are located in non-standard directories, and .BR pkg-config (1) is not available, the output from option .B \-\-libs might be incomplete. . It is thus recommended to use the .BR pkg-config (1) interface instead, which is able to correctly resolve all dependencies. . .PP Setting .B \-\-exec-prefix (either explicitly or implicitly) might return incorrect results if combined with option .BR \-\-static . . The same problem can occur if you set the .B SYSROOT environment variable. . . .SH AUTHOR . This manual page was contributed by Nis Martensen <nis.martensen@web.de>, with further refinements from the FreeType team. . . .\" eof

It previously didn't accept more than one argument correctly. For example, when typing: ./configure --disable-shared --disable-nls the `--disable-nls' was incorrectly sent to the `make' program. 2002-01-29 Werner Lemberg <wl@gnu.org> * README.UNX: Fix typo. * builds/unix/install.mk (uninstall): Fix library name for libtool. 2002-01-28 Francesco Zappa Nardelli <Francesco.Zappa.Nardelli@ens.fr> * src/pcf/pcfdriver.c (PCF_Done_Face): Fix incorrect destruction of the face object (face->toc.tables, face->root.family_name, face->root.available_size, face->charset_encoding, face->charset_registry are now freed). Thanks to Niels Moseley. 2002-01-28 Roberto Alameda <ojancano@geekmail.de> * src/type1/t1load.c (parse_encoding): Set `loader->num_chars'. 2002-01-28 Werner Lemberg <wl@gnu.org> * src/type1/t1load.c (parse_subrs, parse_charstrings): Use copy of `base' string for decrypting to not modify the original data.

This results in a 5-7% speedup in rendering speed. 2002-01-08 David Turner <david@freetype.org> Added some wrapper scripts to make the installation more Unix-friendly. * configure, install: New files. * INSTALL, README.UNX: Updated installation documentation to use the new 'configure' and 'install' scripts. 2002-01-07 David Turner <david@freetype.org> * Version 2.0.6 released. ========================= * docs/BUGS, docs/CHANGES: Updating documentation for 2.0.6 release. * src/tools/docmaker.py: Fixed HTML quoting in sources. (html_format): Replaced with ... (html_quote): New function. (html_quote0): New function. (DocCode::dump_html): Small improvement. (DocParagraph::dump, DocBlock::html): Use html_quote0 and html_quote. * include/freetype/config/ftoption.h: Setting default options for a release build (debugging off, bytecode interpreter off). * src/base/ftobjs.c, src/base/ftoutln.c, src/cache/ftccmap.c, src/cff/cffload.c, src/cff/cffobjs.c, src/pshinter/pshalgo2.c, src/sfnt/ttload.c, src/sfnt/ttsbit.c: Removing small compiler warnings (in pedantic compilation modes). 2002-01-05 David Turner <david@freetype.org> * src/autohint/ahhint.c (ah_align_linked_edge): Modified computation of auto-hinted stem widths; this avoids color fringes in `ClearType-like' rendering. * src/truetype/ttgload.c (TT_Load_Glyph_Header, TT_Load_Simple_Glyph, TT_Load_Composite_Glyph, load_truetype_glyph): Modified the TrueType loader to make it more paranoid; this avoids nasty buffer overflows in the case of invalid glyph data (as encountered in the output of some buggy font converters). 2002-01-04 David Turner <david@freetype.org> * README.UNX: Added special README file for Unix users. * builds/unix/ftsystem.c (FT_New_Stream): Fixed typo. * src/base/ftobjs.c: Added #include FT_OUTLINE_H to get rid of compiler warnings. * src/base/ftoutln.c (FT_Outline_Check): Remove compiler warning. 2002-01-03 Werner Lemberg <wl@gnu.org> * src/type1/t1objs.c (T1_Face_Init): Add cast to avoid compiler warning. 2002-01-03 Keith Packard <keithp@keithp.com> * builds/unix/ftsystem.c (FT_New_Stream): Added a fix to ensure that all FreeType input streams are closed in child processes of a `fork' on Unix systems. This is important to avoid (potential) access control issues. 2002-01-03 David Turner <david@freetype.org> * src/type1/t1objs.c (T1_Face_Init): Fixed a bug that crashed the library when dealing with certain weird fonts like `Stalingrad', in `sadn.pfb' (this font has no full font name entry). * src/base/ftoutln.c, include/freetype/ftoutln.h (FT_Outline_Check): New function to check the consistency of outline data. * src/base/ftobjs.c (FT_Load_Glyph): Use `FT_Outline_Check' to ensure that loaded glyphs are valid. This allows certain fonts like `tt1095m_.ttf' to be loaded even though it appears they contain really funky glyphs. There still is a bug there, though. * src/truetype/ttgload.c (load_truetype_glyph): Fix error condition. 2001-12-30 David Turner <david@freetype.org> * src/autohint/ahhint.c (ah_hinter_load): Fix advance width computation of auto-hinted glyphs. This noticeably improves the spacing of letters in KDE and Gnome. 2001-12-25 Antoine Leca <Antoine-Freetype@Leca-Marti.org> * builds/dos/detect.mk: Correcting the order for Borland compilers: 16-bit bcc was never selected, always overridden by 32-bit bcc32. 2001-12-22 Francesco Zappa Nardelli <Francesco.Zappa.Nardelli@ens.fr> * src/pcf/pcfread.c (pcf_load_font): Handle property `POINT_SIZE' and fix incorrect computation of `available_sizes'. 2001-12-22 David Turner <david@freetype.org> * src/autohint/ahhint.c (ah_hinter_load): Auto-hinted glyphs had an incorrect glyph advance in the case of mono-width fonts (like Courier, Andale Mono, and others). 2001-12-22 Detlef Würkner <TetiSoft@apg.lahn.de> * builds/amiga/*: Adaptations to latest changes. Support added for MorphOS. 2001-12-22 Werner Lemberg <wl@gnu.org> * src/pshinter/pshrec.c (FT_COMPONENT): Redefine to `trace_pshrec'. (ps_mask_table_merge, ps_hints_open, ps_hints_stem, ps_hints_t1stem3, ps_hints_t2mask, ps_hints_t2counter): Fix FT_ERROR messages. * src/pshinter/pshalgo1.c (FT_COMPONENT): Define as `trace_pshalgo1'. * src/pshinter/pshalgo2.c (FT_COMPONENT): Define as `trace_pshalgo2'. * include/freetype/internal/ftdebug.h (FT_Trace): Updated. * docs/modules.txt: New file. 2001-12-21 David Turner <david@freetype.org> * src/pshinter/pshrec.c (ps_hints_t2mask, ps_hints_t2counter): Ignore invalid `hintmask' and `cntrmask' operators (instead of returning an error). Glyph 2028 of the CFF font `MSung-Light-Acro' couldn't be rendered otherwise (it seems its charstring is buggy, though this requires more analysis). (FT_COMPONENT): Define. * src/cff/cffgload.c (CFF_Parse_CharStrings), src/psaux/t1decode.c (T1_Decoder_Parse_Charstrings), src/pshinter/pshalgo2.c (*), Fixed a bug where the X and Y axis where inverted in the postscript hinter. This caused problem when displaying on non-square surfaces. * src/pshinter/pshalgo2.c: s/vertical/dimension/. * src/pshinter/pshglob.c (psh_globals_new): Replaced a floating point constant with a fixed-float equivalent. For some reasons not all compilers are capable of directly computing a floating pointer constant casted to FT_Fixed, and will link a math library instead. 2001-12-20 Werner Lemberg <wl@gnu.org> * src/cache/ftccache.c (ftc_node_destroy, ftc_cache_lookup): Fix tracing strings. * src/cache/ftccmap.c (ftc_cmap_family_init): Ditto. * src/cache/ftcmanag.c (ftc_family_table_alloc, ftc_family_table_free, FTC_Manager_Check): Ditto. * src/cache/ftcsbits.c (ftc_sbit_node_load): Ditto. * src/base/ftobjs.c (FT_Done_Library): Remove compiler warning. 2001-12-20 David Turner <david@freetype.org> Added PostScript hinter support to the CFF and CID drivers. * include/freetype/internal/cfftypes.h (CFF_Font): New member `pshinter'. * src/cff/cffload.c (CFF_Get_Standard_Encoding): New function. * src/cff/cffload.h: Updated. * src/cff/cffgload.c (CFF_Init_Builder): Renamed to ... (CFF_Builder_Init): This. Added new argument `hinting'. (CFF_Done_Builder): Renamed to ... (CFF_Builder_Done): This. (CFF_Init_Decoder): Added new argument `hinting'. (CFF_Parse_CharStrings): Implement vstem support. (CFF_Load_Glyph): Updated. Add hinting support. (cff_lookup_glyph_by_stdcharcode): Use CFF_Get_Standard_Encoding(). (cff_argument_counts): Updated. * src/cff/cffgload.h: Updated. * src/cff/cffobjs.c: Include FT_INTERNAL_POSTSCRIPT_HINTS_H. (CFF_Size_Get_Globals_Funcs, CFF_Size_Done, CFF_Size_Init, CFF_Size_Reset, CFF_GlyphSlot_Done, CFF_GlyphSlot_Init): New functions. (CFF_Init_Face): Renamed to ... (CFF_Face_Init): This. Add hinter support. (CFF_Done_Face): Renamed to ... (CFF_Face_Done): This. (CFF_Init_Driver): Renamed to ... (CFF_Driver_Init): This. (CFF_Done_Driver): Renamed to ... (CFF_Driver_Done): This. * src/cff/cffobjs.h: Updated. * src/cff/cffdrivr.c (cff_driver_class): Updated. * include/freetype/internal/t1types.h (CID_FaceRec): New member `pshinter'. * src/cid/cidgload.c (CID_Load_Glyph): Add hinter support. * src/cid/cidobjs.c: Include FT_INTERNAL_POSTSCRIPT_HINTS_H. (CID_GlyphSlot_Done, CID_GlyphSlot_Init, CID_Size_Get_Globals_Funcs, CID_Size_Done, CID_Size_Init, CID_Size_Reset): New functions. (CID_Done_Face): Renamed to ... (CID_Face_Done): This. (CID_Init_Face): Renamed to ... (CID_Face_Init): This. Add hinting support. (CID_Init_Driver): Renamed to ... (CID_Driver_Init): This. (CID_Done_Driver): Renamed to ...

We need to install it in $(prefix)/share/aclocal/freetype2.m4 but I didn't modify builds/unix/install.mk yet. * INSTALL: Updated the instructions to build shared libraries with Jam. They were simply wrong. * src/base/fttrigon.c (FT_Cos): Fixed a small bug that caused slightly improper results for `FT_Cos' and `FT_Sin' (example: FT_Sin(0) == -1!). 2001-12-11 Detlef Würkner <TetiSoft@apg.lahn.de> * include/freetype/internal/ftstream.h (GET_LongLE, GET_ULongLE): Fixed incorrect argument types. 2001-12-10 Francesco Zappa Nardelli <Francesco.Zappa.Nardelli@ens.fr> * src/pcf/pcfdriver.c (PCF_Init_Face): Allow Xft to use PCF fonts by setting the `face->metrics.max_advance' correctly. 2001-12-07 David Turner <david@freetype.org> * include/freetype/cache/ftccmap.h, src/cache/ftccmap.c: Added new charmap cache. * src/cache/ftcache.c: Updated. * src/autohint/ahhint.c (ah_hinter_hint_edges): s/UNUSED/FT_UNUSED/. 2001-12-06 Leonard Rosenthol <leonardr@lazerware.com> Added support for reading .dfont files on Mac OS X. Also added a new routine which looks up a given font by name in the Mac OS and returns the disk file where it resides. * src/base/ftmac.c: Include <Files.h> and <TextUtils.h>. (is_dfont): New auxiliary function. (FT_New_Face_From_dfont): New function. (FT_GetFile_From_Mac_Name): New exported function.

Comment out use of `origin'. * src/smooth/ftsmooth.c (ft_smooth_render): Fixed a nasty hidden bug where outline shifting wasn't correctly undone after bitmap rasterization. This created problems with certain glyphs (like '"' of certain fonts) and the cache system. * src/pshinter/pshalgo1.c (psh1_hint_table_init): Fix typo. * src/pshinter/pshalgo2.c (psh2_hint_table_init): Fix typo. (ps2_hints_apply): Small fix. 2001-12-05 David Turner <david@freetype.org> * src/pshinter/pshalgo2.c (psh2_hint_table_init), src/pshinter/pshalgo1.c (psh1_hint_table_init): Removed compiler warnings. * include/freetype/ftcache.h, include/freetype/cache/*, src/cache/*: Yet another massive rewrite of the caching sub-system in order to both increase performance and allow simpler cache sub-classing. As an example, the code for the image and sbit caches is now much simpler. I still need to update the documentation in www/freetype2/docs/cache.html to reflect the new design though. * include/freetype/config/ftheader.h (FT_CACHE_CHARMAP_H): New macro. (FT_CACHE_INTERNAL_CACHE_H): Updated. 2001-12-05 David Krause <freetype@davidkrause.com> * docs/license.txt: s/X Windows/X Window System/. 2001-12-04 Werner Lemberg <wl@gnu.org> * src/raster/ftraster.c: Fix definition condition of MEM_Set(). * src/smooth/ftgrays.c (M_Y): Change value to 192. * src/base/ftdbgmem.c (ft_mem_table_destroy): Fix printf() parameter.

Also added comments about the meaning of bit 57 of the `OS/2' table (TT_UCR_SURROGATES) which (with OpenType v.1.3) now means `there is a character beyond 0xFFFF in this font'. Thanks to Detlef Würkner <TetiSoft@apg.lahn.de> for noticing this. 2001-11-20 David Turner <david@freetype.org> * src/pshinter/{pshalgo2.c, pshalgo1.c}: Fixed stupid bug in sorting routine that created nasty alignment artefacts. * src/pshinter/pshrec.c, tests/gview.c: Debugging updates. * src/smooth/ftgrays.c: De-activated experimental gamma support. Apparently, `optimal' gamma tables depend on the monitor type, resolution and general karma, so it's better to compute them outside of the rasterizer itself. (gray_convert_glyph): Use `volatile' keyword. 2001-10-29 David Turner <david@freetype.org> Adding experimental `gamma' support. This produces smoother glyphs at small sizes for very little cost. * src/smooth/ftgrays.c (grays_init_gamma): New function. (gray_raster_new): Use it. Various fixes to the auto-hinter. They merely improve the output of sans-serif fonts. Note that there are still problems with serifed fonts and composites (accented characters). * src/autohint/ahglyph.c (ah_outline_load, ah_outline_link_segments): Implement it. Fix typos. (ah_outline_save, ah_outline_compute_segments): Fix typos. * src/autohint/ahhint.c (ah_align_serif_edge): New argument `vertical'. Implement improvement.

(AH_Hinter): Remove `disable_horz_edges' and `disable_vert_edges' (making them global as `ah_debug_disable_horz' and `ah_debug_disable_vert'). Fix typos. * tests/gview.c: Updated the debugging glyph viewer to show the hints generated by the `autohint' module. 2001-10-27 David Turner <david@freetype.org> * src/cache/ftcchunk.c (ftc_chunk_cache_lookup): Fixed a bug that considerably lowered the performance of the abstract chunk cache. 2001-10-26 David Turner <david@freetype.org> * include/freetype/ftcache.h, include/freetype/cache/*.h, src/cache/*.c: Major re-design of the cache sub-system to provide better performance as well as an `Acquire'/`Release' API. Seems to work well here, but probably needs a bit more testing. 2001-10-26 Leonard Rosenthol <leonardr@lazerware.com> * builds/mac/README: Updated to reflect my taking over the project and that is now being actively maintained. * src/base/ftmac.c (parse_fond): Applied patches from Paul Miller <paulm@profoundeffects.com> to support loading a face other than the first from a FOND resource. (FT_New_Face_From_FOND): Updated. 2001-10-25 Leonard Rosenthol <leonardr@lazerware.com> * builds/mac/ftlib.prj: Update of CodeWarrior project file for Mac OS for latest version (7) of CWPro and for recent changes to the FT source tree. 2001-10-25 David Turner <david@freetype.org> * include/freetype/config/ftoption.h: Updated comments to explain precisely how to use project-specific macro definitions without modifying this file manually. (FT_CONFIG_FORCE_INT64): Define. (FT_DEBUG_MEMORY): New macro. 2001-10-24 Tom Kacvinsky <tkacvins@freetype.org> * builds/unix/ftsystem.c (FT_New_Memory): Added a missing `{'. 2001-10-23 David Turner <david@freetype.org> * include/freetype/internal/ftmemory.h, src/base/ftdbgmem.c: Improvements to the memory debugger to report more information in case of errors. Also, some allocations that occurred through REALLOC couldn't be previously caught correctly. * src/autohint/ahglyph.c (ah_outline_compute_segments, ah_outline_compute_edges), src/raster/ftraster.c (ft_black_new), src/smooth/ftgrays.c (gray_render_span, gray_raster_new): Replaced liberal uses of memset() by the MEM_Set() macro. 2001-10-23 David Turner <david@freetype.org> * src/raster/ftraster.c (Update): Removed to be inlined in ... (Sort): Updated. 2001-10-22 David Turner <david@freetype.org> * builds/unix/ftsystem.c (FT_New_Memory, FT_Done_Memory), builds/vms/ftsystem.c (FT_New_Memory, FT_Done_Memory), builds/amiga/ftsystem.c (FT_New_Memory, FT_Done_Memory), src/base/ftdbgmem.c: Updated the memory debugger and platform-specific implementations of `ftsystem' in order to be able to debug memory allocations on Unix, VMS and Amiga too! * src/pshinter/pshalgo2.c (psh2_hint_table_record_mask): Removed some bogus warnings. * include/freetype/internal/ftmemory.h, src/base/ftdbgmem.c: Modified the debugging memory manager to report the location (source file name + line number) where leaked memory blocks are allocated in the source file. * src/base/ftdbgmem.c: New debugging memory manager. You must define the FT_DEBUG_MEMORY macro in `ftoption.h' to enable it. It will record every memory block allocated and report simple errors like memory leaks and double deletes. * src/base/Jamfile: Include ftdbgmem. * src/base/rules.mk: Ditto. * src/base/ftbase.c: Include ftdbgmem.c. * include/freetype/config/ftoption.h: Added the FT_DEBUG_MEMORY macro definition. * src/base/ftsystem.c (FT_New_Memory, FT_Done_Memory): Modified the base component to use the debugging memory manager when the macro FT_DEBUG_MEMORY is defined. 2001-10-21 Tom Kacvinsky <tkacvins@freetype.org> * src/cff/cffload.c (CFF_Done_Font): Free subfonts array only if we are working with a CID keyed CFF font. Otherwise, a variable that was never allocated memory might freed. This is a correction to the previous patch for freeing subfonts. 2001-10-21 Tom Kacvinsky <tkacvins@freetype.org> * src/cff/cffload.c (CFF_Done_Font): Free the subfonts array to avoid a memory leak. 2001-10-21 David Turner <david@freetype.org> * src/pshinter/pshalgo2.c, src/pshinter/pshalgo1.c, src/pshinter/pshglob.c: Removing compiler warnings in pedantic modes (in multi-object compilation mode, mainly). 2001-10-20 Tom Kacvinsky <tkacvins@freetype.org> * src/type1/t1load.c (parse_encoding): Add a test to make sure that custom encodings (i.e., neither StandardEncoding nor ExpertEncoding) are not loaded twice when the Type 1 font is synthetic. * src/type1/t1load.c (parse_font_name, parse_subrs): Added a test for when loading synthetic fonts to make sure that the font name and subroutines are not loaded twice. This is to remove a memory leak that occurred because the original memory blocks for these objects were not deallocated when the objects were parsed the second time. 2001-10-19 David Turner <david@freetype.org> * src/smooth/ftgrays.c, src/pshinter/pshglob.h, src/pshinter/pshrec.c, src/pshinter/pshalgo2.c: Getting rid of compiler warnings. * src/pshinter/module.mk, src/pshinter/rules.mk: Adding control files to build the PostScript hinter with the `old' build system. 2001-10-19 Jacob Jansen <joukj@hrem.stm.tudelft.nl> * descrip.mms, src/pshinter/descrip.mms: Updates to the VMS build files. 2001-10-18 David Turner <david@freetype.org> * src/psnames/pstables.h, src/tools/glnames.py: Rewrote the `glnames.py' script used to generate the `pstables.h' header file. The old one contained a serious bug that made FreeType return incorrect glyph names for certain glyphs. * src/truetype/ttdriver.c (Set_Char_Sizes): Changing computation of pixel size from character size to use rounding. This is an experiment to see whether this gives values similar to Windows for scaled ascent/descent/etc. * src/base/ftcalc.c (FT_Div64by32): Changed the implementation slightly since the original code was mis-compiled on Mac machines using the MPW C compiler. * src/base/ftobjs.c (FT_Realloc): When a memory block was grown through FT_Realloc(), the new bytes were not set to 0, which created some strange bugs in the PostScript hinter. (destroy_face): Don't deallocate unconditionally. * src/cid/cidgload.c (CID_Compute_Max_Advance, CID_Load_Glyph): Adding support to new PostScript hinter. * include/freetype/internal/psglobal.h, include/freetype/internal/pshints.h, include/freetype/config/ftmodule.h, src/pshinter/Jamfile, src/pshinter/pshalgo.h, src/pshinter/pshalgo1.h, src/pshinter/pshalgo1.c, src/pshinter/pshalgo2.h, src/pshinter/pshalgo2.c, src/pshinter/pshglob.h, src/pshinter/pshglob.c, src/pshinter/pshinter.c, src/pshinter/pshmod.c, src/pshinter/pshmod.h, src/pshinter/pshrec.c, src/pshinter/pshrec.h: Adding new PostScript hinter module. * include/freetype/internal/ftobjs.h, include/freetype/internal/internal.h, include/freetype/internal/psaux.h, include/freetype/internal/t1types.h, src/psaux/psobjs.c, src/psaux/psobjs.h, src/psaux/t1decode.h, src/psaux/t1decode.c, src/type1/t1driver.c, src/type1/t1gload.c, src/type1/t1objs.c, src/type1/t1objs.h: Updates to use the new PostScript hinter. * tests/Jamfile, tests/gview.c: Adding a new glyph hinting viewer/debugger to the source tree. Note that you will _not_ be able to compile it since it depends on an unavailable graphics library named `Nirvana' to render vector images. 2001-10-17 David Turner <david@freetype.org> * Version 2.0.5 released. ========================= * include/freetype/freetype.h, include/internal/ftobjs.h, src/base/ftobjs.c, src/type1/t1driver.c: Adding a new function named 'FT_Get_Postscript_Name' to retrieve the PostScript name of a given font.

This resulted in the unavailability of certain glyphs like `Cacute', `cacute' and `lslash' in Unicode charmaps, even if these were present in the font (causing problems for Polish users). * src/tools/glnames.py (mac_standard_names): Fixed. (t1_standard_strings): Some fixes and renamed to ... (sid_standard_names): This. (t1_expert_encoding): Fixed. (the_adobe_glyph_list): Renamed to ... (adobe_glyph_names): This.

Function names are now all uniformly prefixed with `gray_'. * src/smooth/ftgrays.c: Include <setjmp.h>. (ErrRaster_MemoryOverflow): New macro. (TArea): New type to store area values in each cell (using `int' was too small on 16-bit systems). <limits.h> is included to properly get the needed data type. (TCell, TRaster): Use it. (TRaster): New element `jump_buffer'. (gray_compute_cbox): Use `RAS_ARG' as the only parameter and get `outline' from it. (gray_record_cell): Use longjmp().

This fixes repeated calls of the script. Reported by Nelson Beebe and Behdad Esfahbod. * README.CVS: Mention file permissions. 2005-05-23 Werner Lemberg <wl@gnu.org> * builds/amiga/makefile.os4 (WARNINGS), builds/compiler/gcc-dev.mk (CFLAGS), builds/compiler/gcc.mk (CFLAGS): Remove -fno-strict-aliasing. * src/sfnt/rules.mk (SFNT_DRV_SRC): Don't include ttsbit0.c -- it is currently loaded from ttsbit.c. 2005-05-23 Behdad Esfahbod <behdad@cs.toronto.edu> Say you have `(Foo*)x' and want to assign, pass, or return it as `(Bar*)'. If you simply say `x' or `(Bar*)x', then the C compiler would warn you that type casting incompatible pointer types breaks strict-aliasing. The solution is to cast to `(void*)' instead which is the generic pointer type, so the compiler knows that it should make no strict-aliasing assumption on `x'. But the problem with `(void*)x' is that seems like in C++, unlike C, `void*' is not a generic pointer type and assigning `void*' to `Bar*' without a cast causes an error. The solution is to cast to `Bar*' too, with `(Bar*)(void*)x' as the result -- this is what the patch does. * include/freetype/cache/ftccache.h (FTC_CACHE_LOOKUP_CMP), include/freetype/cache/ftcmru.h (FTC_MRULIST_LOOKUP_CMP): Remove cast on lvalue, use a temporary pointer instead. Cast temporarily to (void*) to not break strict aliasing. * include/freetype/internal/ftmemory.h (FT_MEM_ALLOC, FT_MEM_REALLOC, FT_MEM_QALLOC, FT_MEM_QREALLOC, FT_MEM_FREE), src/base/ftglyph.c (FT_Glyph_To_Bitmap): Cast temporarily to (void*) to not break strict aliasing. * src/base/ftinit.c (FT_USE_MODULE): Fix wrong type information. * builds/unix/configure.ac (XX_CFLAGS): Remove -fno-strict-aliasing. 2005-05-23 David Turner <dturner@freetype.org> Fix Savannah bug #12213 (incorrect behaviour of the cache sub-system in low-memory conditions). * include/freetype/cache/ftccache.h (FTC_CACHE_TRYLOOP, FTC_CACHE_TRYLOOP_END): New macros. * src/cache/ftccache.c (FTC_Cache_NewNode), src/cache/ftcsbits.c (ftc_snode_compare): Use FT_CACHE_TRYLOOP and FTC_CACHE_TRYLOOP_END. 2005-05-23 Werner Lemberg <wl@gnu.org> * src/base/rules.mk (BASE_SRC): Don't add ftsynth.c here but...

The idea is to avoid loading and decoding tables in the heap, and instead access the raw data whenever possible (i.e., when it doesn't compromise performance). This has several benefits: For example, opening vera.ttf now uses just a small amount of memory (even when the FT_Library footprint is accounted for), until you start loading glyphs. Even then, you save at least 20KB compared to the non-optimized case. Performance of various operations, including open and close, has also been dramatically improved. More optimizations to come, especially for the auto-hinter. * include/freetype/internal/sfnt.h (TT_Face_GetKerningFunc): New function type.

Don't define `hdmx', `num_kern_pairs', `kern_table_index', `kern_pairs' if FT_OPTIMIZE_MEMORY is set. * src/base/ftdbgmem.c (ft_mem_table_set): Don't shadow variable. Fix compiler warning. * src/cff/cffdrivr.c (Get_Kerning): Renamed to... (cff_get_kerning): This. Simplify.

Update all callers. * src/truetype/ttgload.h: Updated. 2005-02-22 David Turner <david@freetype.org> * src/base/ftdbgmem.c: Partly rewritten. Added the ability to list all allocation sites in the memory debugger. Also a new function FT_DumpMemory() was added. It is only available in builds with FT_DEBUG_MEMORY defined, and you must declare it in your own code to use it, i.e., with something like: extern void FT_DumpMemory( FT_Memory ); ... FT_DumpMemory( memory ); * include/freetype/config/ftoption.h (TT_CONFIG_OPTION_BYTECODE_INTERPRETER): Comment out definition -- again.

Reported by Dirck Blaskey. 2004-06-24 David Turner <david@freetype.org> * Version 2.1.9 released. ========================= * src/truetype/ttgload.c, src/truetype/ttxgvar.c: Removing compiler warnings. 2004-06-23 Werner Lemberg <wl@gnu.org> * include/freetype/internal/ftmemory.h [FT_DEBUG_MEMORY]: Declare FT_QAlloc_Debug and FT_QRealloc_Debug. * src/base/ftutil.c (FT_QAlloc): Fix error and debug messages. (FT_QRealloc): Call FT_QAlloc if original pointer is NULL. Fix error message. 2004-06-23 David Turner <david@freetype.org> * include/freetype/internal/ftmemory.h, src/base/ftutil.c (FT_QAlloc, FT_QRealloc), src/base/ftdbgmem.c (FT_QAlloc_Debug, FT_QRealloc_Debug): New functions that perform allocation without zero-ing out the corresponding blocks. * include/freetype/internal/ftmemory.h (FT_MEM_QALLOC, FT_MEM_QREALLOC, FT_MEM_QNEW, FT_MEM_QNEW_ARRAY, FT_MEM_QRENEW_ARRAY, FT_QALLOC, FT_QREALLOC, FT_QNEW, FT_QNEW_ARRAY, FT_QRENEW_ARRAY): New macros. * src/base/ftstream.c (FT_Stream_EnterFrame): Use FT_QALLOC. * src/gzip/ftgzip.c (FT_Stream_OpenGzip): Use FT_QNEW_ARRAY. * src/sfnt/sfobjs.c (tt_face_get_name): Use FT_QNEW_ARRAY. * src/sfnt/ttload.c (tt_face_load_directory, tt_face_load_metrics, tt_face_load_gasp): Use FT_QNEW_ARRAY.

This dramatically improves the performance of face open/close operations. For example, putting the TrueType driver first in the list results in a 5x speedup when opening `Vera.ttf'. The very problem is that both the PCF and BDF drivers do a lot more than necessary to detect that they cannot handle a font file. 2004-06-22 Werner Lemberg <wl@gnu.org> * src/pcf/pcfread.c (pcf_read_TOC, pcf_get_properties, pcf_get_metrics, pcf_get_bitmaps, pcf_get_encodings): Improve debugging messages. * src/pcf/pcfdrivr.c (FT_COMPONENT): Move up.

The output now seems to be 100% equivalent to the auto-hinter, while being about 2% faster (which proves that script-specific algorithm selection isn't a performance problem). To test it, change `autohint' to `autofit' in <freetype/config/ftmodule.h> and recompile.

(FNT_Size_Set_Pixels): To find a strike, first check pixel_height only, then try to find a better hit by comparing pixel_width also. Without this fix it isn't possible to access all strikes. Also compute metrics.max_advance to be in sync with other bitmap drivers. * src/base/ftobjs.c (FT_Set_Char_Size): Remove redundant code. (FT_Set_Pixel_Sizes): Assign value to `metrics' after validation of arguments. 2003-06-20 Werner Lemberg <wl@gnu.org> Synchronize computation of height and width for bitmap strikes. The `width' field in the FT_Bitmap_Size structure is now only useful to enumerate different strikes. The `max_advance' field of the FT_Size_Metrics structure should be used to get the (maximum) width of a strike. * src/bdf/bdfdrivr.c (BDF_Face_Init): Don't use AVERAGE_WIDTH for computing `available_sizes->width' but make it always equal to `available_sizes->height'. * src/pcf/pcfread.c (pcf_load_font): Don't use RESOLUTION_X for computing `available_sizes->width' but make it always equal to `available_sizes->height'. * src/truetype/ttdriver.c (Set_Pixel_Sizes): Pass only single argument to function. * src/psnames/psmodule.c (ps_unicode_value): Handle `.' after `uniXXXX' and `uXXXX[X[X]]'. 2003-06-19 Werner Lemberg <wl@gnu.org> * src/bdf/bdfdrivr.c: s/FT_Err_/BDF_Err/. * src/cache/ftccache.c, src/cache/ftcsbits.c, src/cache/ftlru.c: s/FT_Err_/FTC_Err_/. * src/cff/cffcmap.c: s/FT_Err_/CFF_Err_/. * src/pcf/pcfdrivr.c: s/FT_Err_/PCF_Err_/. * src/psaux/t1cmap.c: Include psauxerr.h. s/FT_Err_/PSaux_Err_/. * src/pshinter/pshnterr.h: New file. * src/pshinter/rules.mk: Updated. * src/pshinter/pshalgo.c, src/pshinter/pshrec.c: Include pshnterr.h. s/FT_Err_/PSH_Err_/. * src/pfr/pfrdrivr.c, src/pfr/pfrobjs.c, src/pfr/pfrsbit.c: s/FT_Err_/PFR_Err_/. * src/sfnt/sfdriver.c, src/sfnt/sfobjs.c, src/sfnt/ttcmap0.c, src/sfnt/ttload.c: s/FT_Err_/SFNT_Err_/. * src/truetype/ttgload.c: s/FT_Err_/TT_Err_/. * src/gzip/ftgzip.c: Load FT_MODULE_ERRORS_H and define FT_ERR_PREFIX and FT_ERR_BASE. s/FT_Err_/Gzip_Err_/. 2003-06-19 Dirck Blaskey <listtarget@danbala.com> * src/cff/cffload (cff_encoding_load): `nleft' must be FT_UInt, otherwise adding 1 might wrap the result. 2003-06-18 Werner Lemberg <wl@gnu.org> * src/psnames/psmodule.c (ps_unicode_value): Add support to recognize `uXXXX[X[X]]' glyph names.

In all makefiles `/' is used as the path separator. The conversion to the real path separators is done as late as possible using $(subst ...). . $(HOSTSEP) no longer exists. Now, $(SEP) gives the path separator for the operating system, and the new $(COMPILER_SEP) the path separator for the compiler tools. . $(BUILD) has been renamed to $(BUILD_DIR). In general, all directory variables end with `_DIR'. The variants ending in `_' (like `BASE_' have been removed). The following ChangeLog entries only describe changes which are not related to the redesign. * builds/beos/beos-def.mk (BUILD_DIR): Fix typo. * builds/compiler/watcom.mk (LINK_LIBRARY): Fix linker call to avoid overlong arguments as suggested by J.

There exist fonts (containing e.g. form drawing characters) which intentionally have a zero line gap value. * src/truetype/ttinterp.c (Free_Project, CUR_Func_freeProj): Removed. Unused. Updated all callers. 2003-06-02 Werner Lemberg <wl@gnu.org> * src/cff/cffobjs.c (cff_face_init): Use symbolic names for Adobe specific encoding IDs (there was a wrong EID value for custom encoding). * src/cff/cffcmap.h (CFF_CMapStdRec): Remove `count'. * src/cff/cffcmap.c (cff_cmap_encoding_init, cff_cmap_encoding_done): Updated.

Updated all callers. * src/bdf/bdfdrivr.c (BDF_Face_Init): Set pixel width and height similar to the PCF driver. * src/bdf/bdf.h (_hashnode): Use `const' for `key'. Updated. * src/gzip/ftgzip.c: C++ doesn't like that the array `inflate_mask' is declared twice. It is perhaps better to modify the zlib source files directly instead of this hack. (zcalloc, zfree, ft_gzip_stream_close, ft_gzip_stream_io): Add casts to make build with g++ successful. 2003-04-24 Manish Singh <yosh@gimp.org> * src/cid/cidobjs.c (cid_face_init), src/type1/t1objs.c (T1_Face_Init), src/type42/t42objs.c (T42_Face_Init): Split on `-' also for searching the style name. 2003-04-24 David Turner <david@freetype.org> * src/pcf/pcfread.c (pcf_load_font): Fixed the computation of face->num_glyphs. We must increase the value by 1 to respect the convention that glyph index 0 always corresponds to the `missing glyph'. 2003-04-24 Werner Lemberg <wl@gnu.org> * builds/unix/unix-cc.in (CFLAGS): Add @CPPFLAGS@. 2003-04-24 Dieter Baron <dillo@netbsd.org> * builds/unix/freetype-config.in (cflags): Emit FreeType 2's include files first. Otherwise there are conflicts with FreeType 1 installed simultaneously. 2003-04-23 Werner Lemberg <wl@gnu.org> Fixing bugs reported by Nelson Beebe. * src/base/ftstroker.c (FT_Stroker_ParseOutline): Remove unused variable `in_path'. * src/base/ftobjs (ft_glyphslot_set_bitmap): Change type of second argument to `FT_Byte*'. * include/freetype/internal/ftobjs.h: Updated. * src/bdf/bdflib.c (_bdf_readstream): Remove unused variable `res'.

Otherwise, FT_Panic was called. 2003-03-27 David Turner <david@freetype.org> * README: Updated. * README.UNX: Removed (now replaced by docs/INSTALL.UNX). * src/pshinter/pshalgo3.c: The hinter now performs as in 2.1.3 and will ignore stem quantization only when FT_LOAD_TARGET_SMOOTH is used. (psh3_dimension_quantize_len): Enabled. (psh3_hint_align): Enable commented code. (psh3_hint_align_light): Commented out. * src/base/ftobjs.c (FT_Set_Char_Size): Changed the default computations to include rounding in all cases; this is required to provide accurate kerning data when native TrueType hinting is enabled. * src/type1/t1load.c (is_name_char): The Type 1 loader now accepts more general names according to the PostScript specification (the previous one was too restrictive). (parse_font_name, parse_encoding, parse_charstrings, parse_dict): Use `is_name_char'. (parse_subrs): Handle empty arrays. 2003-03-20 David Turner <david@freetype.org> Serious rewriting of the documentation. * docs/BUGS, docs/BUILD: Removed. * docs/DEBUG.TXT: Renamed to... * docs/DEBUG: This. * docs/CUSTOMIZE, docs/TRUETYPE, docs/UPGRADE.UNX: New files. * docs/INSTALL.ANY, docs/INSTALL.UNX, docs/INSTALL.GNU New files, containing platform specific information previously in INSTALL. * docs/readme.vms: Renamed to... * docs/INSTALL.VMS: This. * docs/*: Updated. Introduced three new functions to deal with glyph bitmaps within FT_GlyphSlot objects: ft_glyphslot_free_bitmap ft_glyphslot_alloc_bitmap ft_glyphslot_set_bitmap These functions are much more convenient to use than managing the FT_GLYPH_OWN_BITMAP flag manually. * include/freetype/internal/ftobjs.h (ft_glyphslot_free_bitmap, ft_glyphslot_alloc_bitmap, ft_glyphslot_set_bitmap): New functions. * src/base/ftobjs.c: Implement them. (ft_glyphslot_done): Use ft_glyphslot_free_bitmap. * src/bdf/bdfdrivr.c (BDF_Glyph_Load), src/pcf/pcfdriver.c (PCF_Glyph_Load): Remove unused variable `memory'. Use `ft_glyphslot_*' functions. Don't set `FT_GLYPH_OWN_BITMAP'. * src/pfr/pfrsbit.c (pfr_slot_load_bitmap): Use `ft_glyphslot_alloc_bitmap'. * src/sfnt/ttsbit.c (Load_SBit_Image): Change 5th argument to type `FT_GlyphSlot'. Adding argument `depth' to handle recursive calls. Use `ft_glyphslot_alloc_bitmap'. (tt_face_load_sbit_image): Remove unused variable `memory'. Don't handle `FT_GLYPH_OWN_BITMAP'. Update call to Load_SBit_Image. * src/type42/t42objs.c (ft_glyphslot_clear): Renamed to... (t42_glyphslot_clear): This. Updated caller. Call `ft_glyphslot_free_bitmap'. * src/winfonts/winfnt.c (FNT_Load_Glyph): Use `ft_glyphslot_set_bitmap'. Don't handle `FT_GLYPH_OWN_BITMAP'. * src/cache/ftlru.c (FT_LruList_Lookup): Fixed an invalid assertion check. * src/autohint/ahglyph.c (ah_outline_load): Add two scaling arguments. * src/autohint/ahglyph.h: Updated. * src/autohint/ahhint.c (ah_hinter_load): Updated. * src/autohint/ahglobal.c (ah_hinter_compute_widths): Updated. * src/cache/ftccache.c (ftc_family_done): Fixed small bug that could crash the cache in rare circumstances (mostly with broken fonts). 2003-03-15 David Turner <david@freetype.org> * src/truetype/ttdriver.c (Set_Char_Sizes): Fixed a small rounding bug. Actually, it seems that previous versions of FreeType didn't perform TrueType rounding exactly as appropriate. 2003-03-14 David Turner <david@freetype.org> * src/truetype/ttdriver.c (Set_Char_Sizes): Fixing the small TrueType native rendering glitches; they came from a small rounding error. 2003-03-13 David Turner <david@freetype.org> Added new environment variables to control memory debugging with FreeType. See the description of `FT2_DEBUG_MEMORY', `FT2_ALLOC_TOTAL_MAX' and `FT2_ALLOC_COUNT_MAX' in DEBUG.TXT. * src/base/ftdbgmem.c (FT_MemTableRec): Add `alloc_count', `bound_total', `alloc_total_max', `bound_count', `alloc_count_max'. (ft_mem_debug_alloc): Handle new variables. (ft_mem_debug_init): s/FT_DEBUG_MEMORY/FT2_DEBUG_MEMORY/. Handle new environment variables. * docs/DEBUG.TXT: Updated. Fixed the cache sub-system to correctly deal with out-of-memory conditions. * src/cache/ftccache.c (ftc_node_destroy): Comment out generic check. (ftc_cache_lookup): Implement loop. * src/cache/ftccmap.c: Define FT_COMPONENT. * src/cache/ftcsbits.c (ftc_sbit_node_load): Handle FT_Err_Out_Of_Memory. * src/cache/ftlru.c: Include FT_INTERNAL_DEBUG_H. (FT_LruList_Lookup): Implement loop. * src/pfr/pfrobjs.c (pfr_face_done): Fix memory leak. (pfr_face_init): Fixing compiler warnings. * src/psaux/psobjs.c (reallocate_t1_table): Fixed a bug (memory leak) that only happened when a try to resize an array would end in an out-of-memory condition. * src/smooth/ftgrays.c (gray_convert_glyph): Removed compiler warnings / volatile bug. * src/truetype/ttobjs.c (tt_glyphzone_done): Removed segmentation fault that happened in tight memory environments. 2003-02-28 Pixel <pixel@mandrakesoft.com> * src/gzip/ftgzip.c (ft_gzip_file_done): Fixed memory leak: The ZLib stream was not properly finalized. 2003-02-25 Anthony Fok <anthony@thizlinux.com> * src/cache/ftccmap.c: Include FT_TRUETYPE_IDS_H. (ftc_cmap_family_init): The cmap cache now supports UCS-4 charmaps when available in Asian fonts. * src/sfnt/ttload.c, src/base/ftobjs.c: Changed `asian' to `Asian' in comments. 2003-02-25 David Turner <david@freetype.org> * src/gzip/ftgzip.c (ft_gzip_file_fill_output): Fixed a bug that caused FreeType to loop endlessly when trying to read certain compressed gzip files. The following test reveals the bug: touch 0123456789 ; gzip 0123456789 ; ftdump 0123456789.gz Several fixes to the PFR font driver: - The list of available embedded bitmaps was not correctly set in the root FT_FaceRec structure describing the face. - The glyph loader always tried to load the outlines when FT_LOAD_SBITS_ONLY was specified. - The table loaded now scans for *undocumented* elements of a physical font's auxiliary data record. This is necessary to retrieve the `real' family and style names. NOTE THAT THESE CHANGES THE FAMILY NAME OF MANY PFR FONTS! * src/pfr/pfrload.c (pfr_aux_name_load): New function. (pfr_phy_font_done): Free `family_name' and `style_name' also. Remove unused variables. (pfr_phy_font_load): Extract useful information from the auxiliary bytes. * src/pfr/pfrobjs.c (pfr_face_done): Set pointers to NULL. (pfr_face_init): Provide fallback values for `family_name' and `style_name'. Handle strikes. (pfr_slot_load): Handle FT_LOAD_SBITS_ONLY. * src/pfr/pfrtypes.h (PFR_PhyFontRec): Add fields `ascent', `descent', `leading', `family_name', and `style_name'. * src/truetype/ttdriver.c (Set_Char_Sizes): Fixed a rounding bug when computing the scale factors for a given character size in points with resolution. * devel/ft2build.h, devel/ftoption.h: New files (in a new directory) which are special development versions of include/ft2build.h and include/freetype/config/ftoption.h, respectively. 2003-02-18 David Turner <david@freetype.org> Fixing the slight distortion problem that occurred due to the latest auto-hinter changes. * src/base/ftobjs.c (ft_recompute_scaled_metrics): Fix rounding. * src/truetype/ttdriver.c (Set_Char_Sizes): New variable `metrics2'. [!TT_CONFIG_OPTION_BYTECODE_INTERPRETER]: Removed. * src/truetype/ttobjs.h (TT_SizeRec): New field `metrics'. * src/truetype/ttobjs.c (Reset_Outline_Size): Fix initialization of `metrics'. [FT_CONFIG_CHESTER_ASCENDER]: Code removed. (Reset_SBit_Size): Fix initialization of `metrics'. * src/truetype/ttinterp.c (TT_Load_Context): Fix initialization of `exec->metrics'. * src/autohint/ahhint.c (ah_hinter_load): Disabled the advance width `correction' which seemed to provide more trouble than benefits. 2003-02-13 Graham Asher <graham.asher@btinternet.com> Changed the incremental loading interface in a way that makes it simpler and allows glyph metrics to be changed (e.g., by adding a constant, as required by CFF fonts) rather than just overridden. This was required to make the GhostScript-to-FreeType bridge work. * src/cff/cffgload.c (cff_slot_load) [FT_CONFIG_OPTION_INCREMENTAL]: Allow metrics to be overridden. * src/cid/cidgload.c (cid_load_glyph) [FT_CONFIG_OPTION_INCREMENTAL]: Ditto. * src/truetype/ttgload.c (load_truetype_glyph) [FT_CONFIG_OPTION_INCREMENTAL]: Simplify. (compute_glyph_metrics) [FT_CONFIG_OPTION_INCREMENTAL]: Code block moved down. * src/type1/t1gload.c (T1_Parse_Glyph_And_Get_Char_String) [FT_CONFIG_OPTION_INCREMENTAL]: Updated. * include/freetype/ftincrem.h: Updated. 2003-01-31 David Turner <david@freetype.org> * docs/CHANGES, docs/VERSION.DLL, docs/TODO: Updating documentation for the 2.1.4 release. * builds/win32/visualc/freetype.dsp, builds/win32/visualc/index.html: Updating the project file for 2.1.4. * src/gzip/adler32.c, src/gzip/ftgzip.c, src/gzip/infblock.c, src/gzip/infcodes.c, src/gzip/inflate.c, src/gzip/inftrees.c, src/gzip/infutil.c: Removed old-style (K&R)function definitions. This avoids warnings with Visual C++ at its most pedantic mode. * src/pfr/pfrsbit.c: Removed compiler warnings. * src/cache/ftccmap.c (ftc_cmap_family_init): Changed an FT_ERROR into an FT_TRACE1 since it caused `ftview' and others to dump too much junk when trying to display a waterfall with a font without a Unicode charmap (e.g. SYMBOL.TTF). Implemented FT_CONFIG_CHESTER_BLUE_SCALE, corresponding to the last patch from David Chester, but with a much simpler (and saner) implementation. * src/autohint/ahhint.c (ah_hinter_load_glyph) [FT_CONFIG_CHESTER_BLUE_SCALE]: Try to optimize the y_scale so that the top of non-capital letters is aligned on a pixel boundary whenever possible. * src/base/ftobjs.c (FT_Set_Char_Size) [FT_CONFIG_CHESTER_BLUE_SCALE]: Round differently. * src/truetype/ttdriver.c (Set_Char_Sizes) [TT_CONFIG_OPTION_BYTECODE_INTERPRETER]: Do some rounding only if this macro is defined. * src/truetype/ttobjs.c (Reset_Outline_Size) [FT_CONFIG_CHESTER_ASCENDER]: Round differently. * src/pshinter/pshalgo3.c: Improved the Postscript hinter. Getting rid of stem snapping seems to work well here (though the stems are still slightly moved to increase contrast). (psh3_dimension_quantize_len): Commented out. (psh3_hint_align_light): New function. (psh3_hint_align): Comment out some code. THIS IMPROVES ANTI-ALIASED RENDERING, BUT MONOCHROME AND LCD MODES STILL SUCK. 2003-01-22 David Chester <davidchester@qmx.net> * src/autohint/ahhint.c (ah_compute_stem_width): Small fix to the stem width optimization. 2003-01-22 David Turner <david@freetype.org> Adding a new API `FT_Get_BDF_Property' to retrieve the BDF properties of a given PCF or BDF font. * include/freetype/ftbdf.h (BDF_PropertyType): New enumeration. (BDF_Property, BDF_PropertyRec): New structure. FT_Get_BDF_Property): New function. * include/freetype/internal/bdftypes.h: Include FT_BDF_H.

(bdf_driver_class): Use `bdf_driver_requester'. * src/pcf/pcfdrivr.c: Include FT_BDF_H. (pcf_get_bdf_property, pcf_driver_requester): New functions (pcf_driver_class): Use `pcf_driver_requester'. * src/pcf/pcfread.c: Include `pcfread.h'. (pcf_find_property): Decorate it with FT_LOCAL_DEF. * src/pcf/pcfread.h: New file, providing `pcf_find_property'. * src/sfnt/ttload.c (sfnt_dir_check): Relaxed the `head' table size verification to accept a few broken fonts who pad the size incorrectly (the table should be padded, but its `size' field shouldn't according to the specification). 2003-01-18 Werner Lemberg <wl@gnu.org> * builds/unix/ltmain.sh: Regenerated with `libtoolize --force --copy' from libtool 1.4.3. * builds/unix/aclocal.m4: Regenerated with `aclocal -I .' from automake 1.7.1. * builds/unix/configure: Regenerated with autoconf 2.54. * builds/unix/config.guess, builds/unix/config.sub: Updated from `config' CVS module at subversions.gnu.org. * builds/unix/install-sh, builds/unix/mkinstalldirs: Updated from `automake' CVS module at subversions.gnu.org. 2003-01-15 David Turner <david@freetype.org> * include/freetype/freetype.h: Fixed documentation for FT_Size_Metrics. 2003-01-15 James Su <suzhe@turbolinux.com.cn> * src/gzip/ftgzip.c (ft_gzip_check_header): Bugfix: couldn't read certain gzip-ed font files (typo: `&&' -> `&'). 2003-01-15 Huw D M Davies <h.davies1@physics.ox.ac.uk> Added a Windows .FNT specific API (mostly for Wine). Also fixed a nasty bug in the header loader which would cause invalid memory overwrites. * include/freetype/config/ftheader.h (FT_WINFONTS_H): New macro for ftwinfnt.h. * include/freetype/internal/fnttypes.h: Include FT_WINFONTS_H. (FNT_FontRec): Updated. Move Windows FNT definition to... * include/freetype/ftwinfnt.h: This new file. (FT_WinFNT_HeaderRec): Rename `reserved2' to `reserved1'. * src/base/ftwinfnt.c: New file, providing `FT_Get_WinFNT_Header'. * src/winfonts/winfnt.c (winfnt_header_fields): Updated. Rename `reserved2' to `reserved1'. (fnt_font_load): Updated. * src/base/Jamfile, src/base/descrip.mms, src/base/rules.mk: Updated. 2003-01-14 Graham Asher <graham.asher@btinternet.com> * include/freetype/ftglyph.h, src/base/ftglyph.c: Added `const' to the type of the first argument to FT_Matrix_Multiply, which isn't changed -- this adds documentation and convenience. 2003-01-13 Graham Asher <graham.asher@btinternet.com> * src/sfnt/ttload.c (tt_face_load_metrics) [FT_CONFIG_OPTION_INCREMENTAL]: TrueType typefaces without horizontal metrics (without the `hmtx' table) are now tolerated if an incremental interface has been specified that has a get_glyph_metrics function, implying that metrics will be supplied from outside. This happens for certain Type 42 fonts passed from GhostScript. 2003-01-11 David Chester <davidchester@qmx.net> Patches to the auto-hinter in order to slightly improve the output. Note that everything is controlled through the new FT_CONFIG_OPTION_CHESTER_HINTS defined in `ftoption.h'. There are also individual FT_CONFIG_CHESTER_XXX macros to control individual `features'. Note that all improvements are enabled by default, but can be tweaked for optimization and testing purposes. The configuration macros will most likely disappear in the short future. * include/freetype/config/ftoption.h (FT_CONFIG_OPTION_CHESTER_HINTS): New macro. (FT_CONFIG_CHESTER_{SMALL_F,ASCENDER,SERIF,STEM,BLUE_SCALE}) [FT_CONFIG_OPTION_CHESTER_HINTS]: New macros to control individual features. * src/autohint/ahglobal.c (blue_chars) [FT_CONFIG_CHESTER_SMALL_F]: Add blue zone for `fijkdbh'. * src/autohint/ahglobal.h (AH_IS_TOP_BLUE) [FT_CONFIG_CHESTER_SMALL_F]: Use `AH_BLUE_SMALL_F_TOP'. * src/autohint/ahglyph.c (ah_outline_compute_edges) [FT_CONFIG_CHESTER_SERIF]: Use `AH_EDGE_SERIF'. (ah_outline_compute_blue_edges) [FT_CONFIG_CHESTER_SMALL_F]: Increase threshold for `best_dist'. * src/autohint/ahhint.c (ah_compute_stem_width) [FT_CONFIG_CHESTER_SERIF]: Provide new version for improved serif handling. (ah_align_linked_edge) [FT_CONFIG_CHESTER_SERIF]: Use special version of `ah_compute_stem_width'. (ah_hint_edges_3) [FT_CONFIG_CHESTER_STEM]: A new algorithm for stem alignment when stem widths are less than 1.5 pixels wide centers the stem slightly off-center of the center of a pixel (this increases sharpness and consistency). [FT_CONFIG_CHESTER_SERIF]: Use special version of `ah_compute_stem_width'. * src/autohint/ahtypes.h [FT_CONFIG_CHESTER_SMALL_F]: Add `AH_BLUE_SMALL_F_TOP'. 2003-01-11 David Turner <david@freetype.org> * include/freetype/internal/fnttypes.h (WinFNT_HeaderRec): Increase size of `reserved2' to avoid memory overwrites. 2003-01-08 Huw Davies <huw@codeweavers.com> * src/winfonts/winfnt.c (winfnt_header_fields): Read 16 bytes into `reserved2', not `reserved'. * src/base/ftobjs.c (find_unicode_charmap): Fixed the error code returned when the font doesn't contain a Unicode charmap. This allows FT2 to load `symbol.ttf' and a few others correctly since the last release. (open_face): Fix return value. 2003-01-08 Owen Taylor <owen@redhat.com> Implemented the FT_RENDER_MODE_LIGHT hinting mode in the auto and postscript hinters. * src/autohint/ahtypes.h (AH_HinterRec): Add `do_stem_adjust'. * src/autohint/ahhint.c (ah_compute_stem_width): Handle hinter->do_stem_adjust. (ah_hinter_load_glyph): Set hinter->do_stem_adjust. * src/pshinter/pshalgo3.h (PSH3_GlyphRec): Add `do_stem_adjust'. * src/pshinter/pshalgo3.c (psh3_hint_align): Use `do_stem_adjust'. (ps3_hints_apply): Handle FT_RENDER_MODE_LIGHT. * include/freetype/freetype.h (FT_Render_Mode): Add FT_RENDER_MODE_LIGHT. * src/truetype/ttgload.c: Fixing the TrueType loader to handle invalid composites correctly by limiting the recursion depth. (TT_MAX_COMPOSITE_RECURSE): New macro. (load_truetype_glyph): Add argument `recurse_count'. Load a composite only if the numbers of contours is -1, emit error otherwise. (TT_Load_Glyph): Updated. 2003-01-08 David Turner <david@freetype.org> * Jamrules, Jamfile, Jamfile.in, src/*/Jamfile: Small changes to support the compilation of FreeType 2 as part of larger projects with their own configuration options (only with Jam). 2003-01-07 David Turner <david@freetype.org> * src/base/ftstroker.c: Probably the last bug-fixes to the stroker; the API is likely to change, however.

(winfnt_header_fields): Updated. (fnt_font_load): Handle version 2 fonts. (FNT_Load_Glyph): Updated. 2002-12-16 David Turner <david@freetype.org> * docs/VERSION.DLL: Updating document to better explain the differences between the three version numbers being used on Unix, as well as providing an autoconf fragment provided by Lars Clausen. * src/smooth/ftgrays.c (gray_render_conic): Fixed small bug that prevented Bézier arcs with negative vertical coordinates to be rendered appropriately. 2002-12-02 Antoine Leca <Antoine-Freetype@Leca-Marti.org> * src/base/ftobjs.c: Modified the logic to get Unicode charmaps. Now it loads UCS-4 charmaps when there is one. (find_unicode_charmap): New function. (open_face): Refer to the above one. (FT_Select_Charmap): Idem. 2002-11-29 Antoine Leca <Antoine-Freetype@Leca-Marti.org> * include/freetype/ftgzip.h: Correct the name of the controlling macro (was __FTXF86_H__ ...). 2002-11-27 Vincent Caron <v.caron@zerodeux.net> * builds/unix/unix-def.in, builds/unix/freetype-config.in, builds/unix/configure.ac, src/gzip/rules.mk, src/gzip/ftgzip.c [FT_CONFIG_OPTION_SYSTEM_ZLIB]: Adding support for system zlib installations if available on the target platform (Unix only). 2002-11-23 David Turner <david@freetype.org> * src/cff/cffload.c (cff_charset_load, cff_encoding_load): Modified charset loader to accept pre-defined charsets, even when the font contains fewer glyphs. Also enforced more checks to ensure that we never overflow the character codes array in the encoding. 2002-11-22 Antoine Leca <Antoine-Freetype@Leca-Marti.org> * include/freetype/ttnameid.h: Updated to latest OpenType specification. 2002-11-18 David Turner <david@freetype.org> * Version 2.1.3 released. ========================= 2002-11-07 David Turner <david@freetype.org> * src/cache/ftcsbits.c (ftc_sbit_node_load): Fixed a small bug that caused problems with embedded bitmaps. * src/otlayout/otlayout.h, src/otlayout/otlconf.h, src/otlayout/otlgsub.c, src/otlayout/otlgsub.h, src/otlayout/otlparse.c, src/otlayout/otlparse.h, src/otlayout/otlutils.h: Updating the OpenType Layout code, adding support for the first GSUB lookups.

This allows the build system to define them depending on the configuration (typically by adding -D flags at compile time). * src/sfnt/ttcmap0.c (tt_face_build_cmaps): Removed compiler warnings in optimized mode relative to the `volatile' local variables. This was not a compiler bug after all, but the fact that a pointer to a volatile variable is not the same as a volatile pointer to a variable :-) The fix was to change `volatile FT_Byte* p' into `FT_Byte* volatile p'. * src/pfr/pfrload.c (pfr_phy_font_load), src/pfr/pfrdrivr.c (pfr_get_metrics), src/gzip/inftrees.c: Removed compiler warnings in optimized modes. * src/gzip/*.[hc]: Modified our zlib copy in order to prevent exporting any zlib function names outside of the component.

(FT_EXPORT, FT_EXPORT_DEF, FT_DEBUG_LEVEL_ERROR, FT_DEBUG_LEVEL_TRACE, FT_DEBUG_MEMORY): Comment out definitions so that platform specific configuration file can override. * include/freetype/internal/ftstream.h: Include FT_SYSTEM_H. 2002-10-30 David Turner <david@freetype.org> * FreeType 2.1.3rc3 released. 2002-10-25 David Turner <david@freetype.org> * include/freetype/ftcache.h (FT_POINTER_TO_ULONG): New macro. (FTC_FACE_ID_HASH): Rewritten, using FT_POINTER_TO_ULONG. 2002-10-22 Giuseppe Ghibò <ghibo@mandrakesoft.com> * include/freetype/freetype.h (FT_Encoding): Fix entry for latin-2. 2002-10-07 Werner Lemberg <wl@gnu.org> * include/freetype/freetype.h (FT_Open_Face): Use `const' for `args' (suggested by Graham). * src/base/ftobjs.c (FT_Open_Face): Updated. (ft_input_stream_new): Ditto. 2002-10-05 David Turner <david@freetype.org> Adding support for embedded bitmaps to the PFR driver, and rewriting its kerning loader/handler to use all kerning pairs in a physical font (and not just the first item). * src/pfr/pfr.c: Include `pfrsbit.c'. * src/pfr/pfrgload.c: Include `pfrsbit.h'. * src/pfr/pfrload.c (pfr_extra_item_load_kerning_pairs): Rewritten.

(tt_face_*): This. 2002-08-27 Werner Lemberg <wl@gnu.org> * docs/VERSION.DLL: New file. 2002-08-23 Graham Asher <graham.asher@btinternet.com> * src/cff/cffgload.c (cff_operator_seac) [FT_CONFIG_OPTION_INCREMENTAL]: Incremental fonts (actually not incremental in the case of CFF but just using callbacks to get glyph recipes) pass the character code, not the glyph index, to the get_glyph_data function; they have no valid charset table. * src/cff/cffload.c (cff_font_load): Removed special cases for FT_CONFIG_OPTION_INCREMENTAL, which are no longer necessary; CFF fonts provided via the incremental interface now have to conform more closely to the CFF font format. * src/cff/cffload.h (cff_font_load): Removed argument now unneeded. * src/cff/cffobjs.c (cff_face_init): Changed call to cff_font_load to conform with new signature. 2002-08-22 David Turner <david@freetype.org> * src/base/ftobject.c, src/base/ftsynth.c, src/base/ftstroker.c, src/bdf/bdfdrivr.c: Removed compiler warnings. 2002-08-21 Werner Lemberg <wl@gnu.org> * src/pshinter/pshalgo3.c (psh3_glyph_compute_inflections, psh3_glyph_compute_extrema, psh3_hint_table_find_strong_point): Fix compiler warnings and resolve shadowing of local variables. 2002-08-21 David Turner <david@freetype.org> The automatic and Postscript hinter now automatically detect inflection points in glyph outlines and treats them specially. This is very useful to prevent nasty effect like the disappearing diagonals of `S' and `s' in many, many fonts. * src/autohint/ahtypes.h (ah_flag_inflection): New macro. * src/autohint/ahangles.c (ah_angle_diff): New function. * src/autohint/ahangles.h: Updated. * src/autohint/ahglyph.c (ah_outline_compute_inflections): New function.

This should only break binary and/or source compatibility on 16-bit platforms (Atari?). (FT_LOAD_NO_AUTOHINT): New macro. * src/base/ftobjs.c (FT_Load_Glyph): Updated. Handle FT_LOAD_NO_AUTOHINT. (FT_Load_Char): Updated. * src/pshinter/pshalgo3.c, src/base/ftobjs.c, src/base/ftobject.c, src/autohint/ahglyph.c, include/freetype/freetype.h: Fixing typos and removing compiler warnings. 2002-08-20 Werner Lemberg <wl@gnu.org> * src/truetype/ttgload.c (TT_Get_Metrics): Add guard for k = 0. 2002-08-20 David Turner <david@freetype.org> * src/pshinter/pshalgo1.c, src/pshinter/pshalgo2.c, src/pshinter/pshglob.c, src/pshinter/pshrec.c, src/autohint/ahmodule.c [DEBUG_HINTER]: Removing compiler warnings (only used in development builds anyway). Improve support of local extrema and stem edge points. * src/pshinter/pshalgo3.h (PSH3_Hint_TableRec): Use PSH3_ZoneRec for `zones'. (PSH3_DIR_UP, PSH3_DIR_DOWN): Exchange values. (PSH3_DIR_HORIZONTAL, PSH3_DIR_VERTICAL): New macros. (PSH3_DIR_COMPARE, PSH3_DIR_IS_HORIZONTAL, PSH3_IS_VERTICAL): New macros. (PSH3_POINT_INFLEX): New enum. (psh3_point_{is,set}_{off,inflex}): New macros. (PSH3_POINT_{EXTREMUM,POSITIVE,NEGATIVE,EDGE_MIN,EDGE_MAX): New enum values. (psh3_point_{is,set}_{extremum,positive,negative,edge_min,edge_max}): New macros. (PSH3_PointRec): New members `flags2' and `org_v'. (PSH3_POINT_EQUAL_ARG, PSH3_POINT_ANGLE): New macros. * src/pshinter/pshalgo3.c [DEBUG_HINTER]: Removing compiler warnings. (COMPUTE_INFLEXS): New macro. (psh3_hint_align): Simplify some basic arithmetic computations. (psh3_point_is_extremum): Removed. (psh3_glyph_compute_inflections) [COMPUTE_INFLEXS]: New function. (psh3_glyph_init) [COMPUTE_INFLEXS]: Use it. (psh3_glyph_compute_extrema): New function. (PSH3_STRONG_THRESHOLD): Increased to 30. (psh3_hint_table_find_strong_point): Improved. (psh3_glyph_find_strong_points, psh3_glyph_interpolate_strong_points): Updated. (psh3_hints_apply): Use psh3_glyph_compute_extrema. * test/gview.c (draw_ps3_hint, ps3_draw_control_points): New functions. Other small updates. * Jamfile: Small updates. 2002-08-18 Arkadiusz Miskiewicz <misiek@pld.ORG.PL> * builds/unix/install.mk (install, uninstall): Add $(DESTDIR) to make life easier for package maintainers. 2002-08-18 Werner Lemberg <wl@gnu.org> * src/pcf/pcfdriver.c (PCF_Glyph_Load): Fix computation of horiBearingX. * src/bdf/bdfdrivr.c (BDF_Glyph_Load): Fix computation of horiBearingY. 2002-08-16 George Williams <gww@silcom.com> Add support for Apple composite glyphs. * include/freetype/config/ftoption.h (TT_CONFIG_OPTION_COMPONENT_OFFSET_SCALED): New macro. * src/truetype/ttgload.c (OVERLAP_COMPOUND, SCALED_COMPONENT_OFFSET, UNSCALED_COMPONENT_OFFSET): New macros for additional OpenType glyph loading flags. (load_truetype_glyph): Implement it. 2002-08-16 Werner Lemberg <wl@gnu.org> * src/cff/cffgload.c (cff_free_glyph_data), src/cff/cffload.c (cff_font_load): Use FT_UNUSED. 2002-08-15 Werner Lemberg <wl@gnu.org> * src/base/ftglyph.c (FT_Glyph_To_Bitmap): Initialize `error'. * src/sfnt/sfobjs.c (SFNT_Load_Face): Fix compiler warning. 2002-08-15 Graham Asher <graham.asher@btinternet.com> Implemented the incremental font loading system for the CFF driver. Tested using the GhostScript-to-FreeType bridge (under development). * src/cff/cffgload.c (cff_get_glyph_data, cff_free_glyph_data): New functions. (cff_operator_seac, cff_compute_max_advance, cff_slot_load): Use them. * src/cff/cffload.c (cff_font_load): Add `face' parameter. Load charset and encoding only if there are glyphs. [FT_CONFIG_OPTION_INCREMENTAL]: Incremental fonts don't need character recipes. * src/cff/cffload.h, src/cff/cffobjs.c: Updated. * src/cid/cidgload.c (cid_load_glyph) [FT_CONFIG_OPTION_INCREMENTAL]: Corrected the incremental font loading implementation to use the new system introduced on 2002-08-01. 2002-08-06 Werner Lemberg <wl@gnu.org> * src/cff/cffcmap.c: Remove compiler warnings. * src/cache/ftccache.c, src/cache/ftccache.i, src/pfr/pfrload.c, src/pfr/pfrgload.c: s/index/idx/. * src/cff/cffload.c: s/select/fdselect/. * src/raster/ftraster.c: s/wait/waiting/. 2002-08-01 Graham Asher <graham.asher@btinternet.com> * src/type1/t1load.c (T1_Open_Face): Tolerate a face with no charstrings if there is an incremental loading interface. Type 1 faces supplied by PostScript interpreters like GhostScript will typically not provide any charstrings at load time, so this is essential if they are to work. 2002-08-01 Graham Asher <graham.asher@btinternet.com> Modified incremental loading interface to be closer to David's preferences. The header freetype.h is not now affected, the interface is specified via an FT_Parameter, the pointer to the interface is hidden in an internal part of the face record, and all the definitions are in ftincrem.h. * include/freetype/freetype.h [FT_CONFIG_OPTION_INCREMENTAL]: Removed. * include/freetype/internal/ftobjs.h [FT_CONFIG_OPTION_INCREMENTAL]: Include FT_INCREMENTAL_H. (FT_Face_InternalRec) [FT_CONFIG_OPTION_INCREMENTAL]: Add `incremental_interface'. * src/base/ftobjs.c (open_face, FT_Open_Face) [FT_CONFIG_OPTION_INCREMENTAL]: Updated. * src/sfnt/sfobjs.c (SFNT_Load_Face) [FT_CONFIG_OPTION_INCREMENTAL]: Updated. * src/truetype/ttgload.c (load_truetype_glyph) [FT_CONFIG_OPTION_INCREMENTAL]: Updated. Free loaded glyph data properly. (compute_glyph_metrics, TT_Load_Glyph) [FT_CONFIG_OPTION_INCREMENTAL]: Updated. * src/truetype/ttobjs.c (TT_Face_Init) [FT_CONFIG_OPTION_INCREMENTAL]: Updated. * src/type1/t1gload.c (T1_Parse_Glyph_And_Get_Char_String) [FT_CONFIG_OPTION_INCREMENTAL]: Updated. (T1_Parse_Glyph) [FT_CONFIG_OPTION_INCREMENTAL]: Updated. Free loaded glyph data properly. (T1_Load_Glyph): Updated. [FT_CONFIG_OPTION_INCREMENTAL]: Free loaded glyph data properly. 2002-07-30 David Turner <david@freetype.org> * include/freetype/ftincrem.h: Adding new experimental header file to demonstrate a `cleaner' API to support incremental font loading. * include/freetype/config/ftheader.h (FT_INCREMENTAL_H): New macro. * src/tools/docmaker/*: Adding new (more advanced) version of the DocMaker tool, using Python's sophisticated regexps. 2002-07-28 Werner Lemberg <wl@gnu.org> s/ft_memset/FT_MEM_SET/. s/FT_MEM_SET/FT_MEM_ZERO/ where appropriate. 2002-07-27 Werner Lemberg <wl@gnu.org> * src/sfnt/ttload.c (sfnt_dir_check): Make it work with TTCs. 2002-07-26 Werner Lemberg <wl@gnu.org> * src/truetype/ttgload.c (load_truetype_glyph) [FT_CONFIG_OPTION_INCREMENTAL]: s/memset/ft_memset/. * src/autohint/ahhint.c (ah_hint_edges_3): Fix compiler warning. * src/cff/cffload.c (cff_encoding_load): Remove `memory' variable. * src/cff/cffcmap.c (cff_cmap_encoding_init): Remove `psnames' variable. * src/truetype/ttgload.c (load_truetype_glyph): Remove statement without effect. * src/truetype/ttdriver (Get_Char_Index, Get_Next_Char): Removed. * src/pshinter/pshalgo3.c (psh3_hint_table_record, psh3_hint_table_init, psh3_hint_table_activate_mask): Fix error message. 2002-07-24 Graham Asher <graham.asher@btinternet.com> * src/truetype/ttobjs.c: Fix for bug reported by Sven Neumann [sven@gimp.org] on the FreeType development forum: `If FT_CONFIG_OPTION_INCREMENTAL is undefined (this is the default), the TrueType loader crashes in line 852 of src/truetype/ttgload.c when it tries to access face->glyph_locations.' 2002-07-18 Graham Asher <graham.asher@btinternet.com> Added types and structures to support incremental typeface loading. The FT_Incremental_Interface structure, defined in freetype.h, is designed to be passed to FT_Open_Face to provide callback functions to obtain glyph recipes and metrics, for fonts like those passed from PostScript that do not necessarily provide all, or any, glyph information, when first opened. * include/freetype/config/ftoption.h (FT_CONFIG_OPTION_INCREMENTAL): New configuration macro to enable incremental face loading. By default it is not defined. * include/freetype/freetype.h (FT_Basic_Glyph_Metrics, FT_Get_Glyph_Data_Func, FT_Get_Glyph_Metrics_Func, FT_Incremental_Interface_Funcs, FT_Incremental_Interface) [FT_CONFIG_OPTION_INCREMENTAL]: New.

(FT_Data): New structure to represent binary data. * src/base/ftobjs.c (open_face) [FT_CONFIG_OPTION_INCREMENTAL]: Add parameter for incremental loading. (FT_Open_Face) [FT_CONFIG_OPTION_INCREMENTAL]: Use incremental interface. * src/truetype/ttgload.c (load_truetype_glyph) [FT_CONFIG_OPTION_INCREMENTAL]: Added the incremental loading system for the TrueType driver. (compute_glyph_metrics): Return FT_Error. [FT_CONFIG_OPTION_INCREMENTAL]: Check for overriding metrics. (TT_Load_Glyph) [FT_CONFIG_OPTION_INCREMENTAL]: Don't look for the glyph table while handling an incremental font. Get glyph offset. * src/truetype/ttobjs.c (TT_Face_Init) [FT_CONFIG_OPTION_INCREMENTAL]: Added the incremental loading system for the TrueType driver. * src/cid/cidgload.c (cid_load_glyph) [FT_CONFIG_OPTION_INCREMENTAL]: Added the incremental loading system for the CID driver. * src/sfnt/sfobjs.c (SFNT_Load_Face) [FT_CONFIG_OPTION_INCREMENTAL]: Changes to support incremental Type 42 fonts: Assume a font has glyphs if it has an incremental interface object. * src/type1/t1gload.c (T1_Parse_Glyph): Renamed to... (T1_Parse_Glyph_And_Get_Char_String): This. [FT_CONFIG_OPTION_INCREMENTAL]: Added support for incrementally loaded Type 1 faces. (T1_Parse_Glyph): New function. (T1_Load_Glyph): Updated. 2002-07-17 David Turner <david@freetype.org> Cleaning up the cache sub-system code; linear hashing is now the default. * include/freetype/cache/ftccache.h, src/cache/ftccache.i, src/cache/ftccache.c [!FTC_CACHE_USE_LINEAR_HASHING]: Removed.

The new cmap code is now the default. * src/type42/t42objs.c (T42_CMap_CharIndex, T42_CMap_CharNext): Removed. * src/type42/t42objs.h: Updated. * src/cid/cidriver.c (Cid_Get_Char_Index, Cid_Get_Next_Char): Removed. (t1cid_driver_class): Updated. * src/truetype/ttdriver.c (tt_driver_class): Updated. * src/type1/t1driver.c (Get_Char_Index, Get_Next_Char): Removed (t1_driver_class): Updated. * src/type42/t42drivr.c (t42_driver_class): Updated. * src/base/ftobjs.c (open_face): Select Unicode cmap by default. * src/sfnt/ttload.c (TT_Load_SFNT_Header): Fixed a recent bug that prevented OpenType fonts to be recognized by FreeType. 2002-07-11 David Turner <david@freetype.org> Changing the SFNT loader to check for SFNT-based font files differently. We now ignore the range `helper' fields and check the `head' table's magic number instead. * include/freetype/internal/tttypes.h (SFNT_HeaderRec): Add `offset' field. * src/sfnt/ttload.c (sfnt_dir_check): New function. (TT_Load_SFNT_HeaderRec): Renamed to... (TT_Load_SFNT_Header): This. Implement new functionality. * src/sfnt/ttload.h: Updated. * src/sfnt/sfdriver.c (sfnt_interface): Updated. * src/base/ftobject.c, src/base/fthash.c: Updated object sub-system and dynamic hash table implementation (still experimental, don't use). * include/freetype/internal/fthash.h: Updated. * include/freetype/internal/ftobjs.h (FT_LibraryRec): New member `meta_class'. Fixing a bug in the Type 1 loader that prevented valid font bounding boxes to be loaded from multiple master fonts. * include/freetype/t1tables.h (PS_BlendRec): Add `bboxes' field. * include/freetype/internal/psaux.h (T1_FieldType): Add `T1_FIELD_TYPE_BBOX'. (T1_FieldLocation): Add `T1_FIELD_LOCATION_BBOX'.

Add `count' member. (CFF_FontRec): Add `psnames' member. * src/cff/cffdrivr.c, src/cff/cffload.c, src/cff/cffload.h, src/cff/cffobjs.c, src/cff/cffobjs.h, src/cff/cffparse.c, src/cffparse.h, src/cff/cffgload.c, src/cff/cffgload.h: Adding support for CFF charmaps, reformatting the sources, and removing some bugs in the Encoding and Charset loaders. Many fonts renamed to use lowercase only: CFF_Builder_Init -> cff_builder_init CFF_Builder_Done -> cff_builder_done CFF_Init_Decoder -> cff_decoder_init CFF_Parse_CharStrings -> cff_decoder_parse_charstrings CFF_Load_Glyph -> cff_slot_load CFF_Init_Decoder -> cff_decoder_init CFF_Prepare_Decoder -> cff_decoder_prepare CFF_Get_Standard_Encoding -> cff_get_standard_encoding CFF_Access_Element -> cff_index_access_element CFF_Forget_Element -> cff_index_forget_element CFF_Get_Name -> cff_index_get_name CFF_Get_String -> cff_index_get_sid_string CFF_Get_FD -> cff_fd_select_get CFF_Done_Charset -> cff_charset_done CFF_Load_Charset -> cff_charset_load CFF_Done_Encoding -> cff_encoding_done CFF_Load_Encoding -> cff_encoding_load CFF_Done_SubFont -> cff_subfont_done CFF_Load_Font -> cff_font_load CFF_Done_Font -> cff_font_done CFF_Size_Get_Globals_Funcs -> cff_size_get_globals_funcs CFF_Size_Done -> cff_size_done CFF_Size_Init -> cff_size_init CFF_Size_Reset -> cff_size_reset CFF_GlyphSlot_Done -> cff_slot_done CFF_GlyphSlot_Init -> cff_slot_init CFF_StrCopy -> cff_strcpy CFF_Face_Init -> cff_face_init CFF_Face_Done -> cff_face_done CFF_Driver_Init -> cff_driver_init CFF_Driver_Done -> cff_driver_done CFF_Parser_Init -> cff_parser_init CFF_Parser_Run -> cff_parser_run add_point -> cff_builder_add_point add_point1 -> cff_builder_add_point1 add_contour -> cff_builder_add_contour close_contour -> cff_builder_close_contour cff_explicit_index -> cff_index_get_pointers 2002-07-09 Owen Taylor <owen@redhat.com> * src/pshinter/pshglob.c (psh_globals_new): Fixed a bug that prevented the hinter from using correct standard width and height values, resulting in hinting bugs with certain fonts (e.g. Utopia). 2002-07-07 David Turner <david@freetype.org> * src/base/ftglyph.c (FT_Glyph_To_Bitmap): Added code to return successfully when the function is called with a bitmap glyph (the previous code simply returned with an error). * docs/DEBUG.TXT: Adding debugging support documentation. * src/base/ftdebug.c (ft_debug_init), builds/win32/ftdebug.c (ft_debug_init), builds/amiga/src/ftdebug.c (ft_debug_init): Changed the syntax of the FT2_DEBUG environment variable used to control debugging output (i.e. logging and error messages).

They provide a new API (FT_Get_X11_Font_Format) to retrieve an X11-compatible string describing the font format of a given face. This was put in a new optional base source file, corresponding to a new public header (named FT_XFREE86_H since this function should only be used within the XFree86 font server IMO). * include/freetype/config/ftheader.h (FT_XFREE86_H): New macro (not documented yet). * src/base/fttype1.c: New file, providing two new API functions (FT_Get_PS_Font_Info and FT_Has_PS_Glyph_Names). * include/freetype/t1tables.h: Updated. * src/base/Jamfile, src/base/rules.mk, src/base/descrip.mms: Updating build control files for the new files `ftxf86.c' and `fttype1.c' in src/base. * src/pshinter/pshglob.c (psh_blues_scale_zones): Fixed a bug that prevented family blue zones substitution from happening correctly. * include/freetype/ftbdf.h FT_Get_BDF_Charset_ID): Adding documentation comment. 2002-05-28 Werner Lemberg <wl@gnu.org> * src/base/ftnames.c (FT_Get_Sfnt_Name): Don't use FT_STREAM_READ_AT but FT_STREAM_READ.

It now ignores empty name entries, entries with invalid pointer Offsets and certain fonts containing tables with broken `storageOffset' fields. Name strings are now loaded on demand, which reduces the memory requirements for a given FT_Face tremendously (for example, the name table of Arial.ttf is about 10Kb and contains 70 names). This is a temporary fix. The whole name table loader and interface will be rewritten in a much more cleanly way shortly, once CSEH have been introduced in the sources. * include/freetype/internal/tttypes.h (TT_NameEntryRec): Change type of `stringOffset' to FT_ULong.

(TT_Free_Names): Updated. 2002-05-24 Tim Mooney <enchanter@users.sourceforge.net> * builds/unix/ft-munmap.m4: New file, extracted FT_MUNMAP_DECL and FT_MUNMAP_PARAM from aclocal.m4 into here, so aclocal.m4 can be rebuilt from sources. Set macro serial to 1, and use third argument to AC_DEFINE for our two custom symbols, so ftconfig.in could one day be rebuilt with autoheader (not recommended now, ftconfig.in is a custom source file) 2002-05-22 Werner Lemberg <wl@gnu.org> * include/freetype/config/ftheader.h (FT_BEZIER_H): Removed. (FT_BDF_H): New macro for accessing `ftbdf.h'. * src/type42/t42drivr.c (hexval): Fix typo. 2002-05-21 Martin Muskens <mmuskens@aurelon.com> * src/psaux/psobjs.c (T1Radix): New function. (t1_toint): Use it to handle numbers in radix format. * src/psaux/t1decode.c (T1_Decoder_Parse_Charstrings): Add dummy for undocumented, obsolete opcode 15. 2002-05-21 David Turner <david@freetype.org> * src/bdf/bdflib.c: Removed compiler warning, and changed all tables to the `static const' storage specifier (instead of simply `static'). * src/type42/t42drivr.c (hexval): Use more efficient code. Removing compiler warnings. * src/bdf/bdfdrivr.c: Removing compiler warnings. * include/freetype/internal/ftbdf.h, src/base/ftbdf.c, src/base/descrip.mms, src/base/Jamfile, src/base/rules.mk (FT_Get_BDF_Charset_ID): New API to retrieve BDF-specific strings from a face.

It has been never used. 2002-05-21 Roberto Alameda <ojancano@geekmail.de>. * src/type42/t42drivr.c: s/T42_ENCODING_TYPE_/T1_ENCODING_TYPE_/. (parse_font_matrix): Remove unnecessary code. (parse_sfnts): Initialize some variables. (t42_driver_class) [TT_CONFIG_OPTION_BYTECODE_INTERPRETER]: Use ft_module_driver_has_hinter conditionally.

Also improved the name table parser to be able to load Windows-encoded entries before Macintosh or Unicode ones, since it seems some fonts don't have reliable values here anyway. * include/freetype/internal/psnames.h: Add typedef for `PSNames_Service'. 2002-03-05 Werner Lemberg <wl@gnu.org> * builds/unix/aclocal.m4, builds/unix/ltmain.sh: Update to libtool 1.4.2.

Added the declarations of FT_Get_First_Char and FT_Get_Next_Char. * src/base/ftobjs.c: Implement FT_Get_First_Char and FT_Get_Next_Char. * include/freetype/t1tables.h: Renaming structure types. This typedef T1_Struct_ { } T1_Struct; becomes typedef PS_StructRec_ { } PS_StructRec, *PS_Struct; typedef PS_StructRec T1_Struct; /* backward compatibility */ Hence, we increase the coherency of the source code by effectively using the `Rec' prefix for structure types. 2002-02-27 David Turner <david@freetype.org> * src/sfnt/ttload.c (TT_Load_Names): Simplifying and securing the names table loader. Invalid individual name entries are now handled correctly. This allows the loading of very buggy fonts like `foxjump.ttf' without allocating tons of memory and causing crashes. * src/otlayout/otlcommon.h, src/otlayout/otlcommon.c: Adding (still experimental) code for OpenType Layout tables validation and parsing. * src/type1/t1cmap.h, src/type1/t1cmap.c: Adding (still experimental) code for Type 1 charmap processing. * src/sfnt/ttcmap0.c: New file.

Trace levels can now be specified within the `FT2_DEBUG' environment variable. See the comments within `ftdebug.c' for more details. * src/base/ftdebug.c: (FT_SetTraceLevel): Removed. (ft_debug_init): New function. (ft_debug_dummy): Removed. Updated to changes in ftdebug.h * include/freetype/internal/ftdebug.h: Always define FT_DEBUG_LEVEL_ERROR if FT_DEBUG_LEVEL_TRACE is defined. (FT_Assert): Renamed to ... (FT_ASSERT): This. Some stuff from ftdebug.h has been moved to ... * include/freetype/internal/fttrace.h: New file, to define the trace levels used for debugging. It is used both to define enums and toggle names for FT2_DEBUG. * include/freetype/internal/internal.h: Updated. * src/base/ftobjs.c, src/base/ftstream.c: Updated. * include/freetype/internal/ftextend.h, src/base/ftextend.c: Removed.

2021-07-18 Werner Lemberg <wl@gnu.org> * Version 2.11.0 released. ========================== Tag sources with `VER-2-11-0'. * docs/VERSION.TXT: Add entry for version 2.11.0. * docs/CHANGES: Updated. * README, src/base/ftver.rc, builds/windows/vc2010/index.html, builds/windows/visualc/index.html, builds/windows/visualce/index.html, builds/wince/vc2005-ce/index.html, builds/wince/vc2008-ce/index.html, docs/freetype-config.1: s/2.10.4/2.11.0/, s/2104/2110/. * include/freetype/freetype.h (FREETYPE_MINOR): Set to 11. (FREETYPE_PATCH): Set to 0. * builds/unix/configure.raw (version_info): Set to 24:0:18. * CMakeLists.txt (VERSION_MINOR): Set to 11. (VERSION_PATCH): Set to 0. * builds/toplevel.mk (dist): Ignore more git-related files. 2021-07-17 David Turner <david@freetype.org> * src/smooth/ftgrays.c: Fix compilation if `FT_LONG64` is undefined. The code assumed that if `__SSE2__` is defined, then 64-bit integer types are available. This is not the case apparently for certain multilib compiler targets like 'x86_32.x86' used by Gentoo. This patch fixes the issue by disabling the special code path when 64-bit integer types are not available. Fixes #1071. 2021-07-16 Alex Richardson <Alexander.Richardson@cl.cam.ac.uk> [tests] Allow arbitrary build directories. * tests/issue-1063/main.c (main): I am building with a build directory that is not directly inside the source tree, so the path `../tests/data/As.I.Lay.Dying.ttf` does not resolve to the test input file. This change passes the test data directory as an environment variable to allow arbitrary build directories. * tests/meson.build: Updated. 2021-07-16 Alex Richardson <Alexander.Richardson@cl.cam.ac.uk> * tests/issue-1063/main.c (main): Fix uninitialized variable. I tried running `meson test` but the test just crashed and gdb reported that the face argument to `FT_Get_Char_Index` was nonsense. With this change the test prints 'Could not open file: ' as it should. 2021-07-16 Werner Lemberg <wl@gnu.org> [smooth] Minor fixes. * src/smooth/ftgrays.c (gray_render_conic): Move variable and structure declarations to beginning of function. Inspite of C99 compliance we still do this for the sake of backward compatibility. This also avoids a shadowing declaration of `count`. (gray_convert_glyph_inner): Fix typo. 2021-07-15 Ben Wagner <bungeman@chromium.org> * src/smooth/ftgrays.c: Guard inclusion of `emmintrin.h`. Guard inclusion of `emmintrin.h` with `#ifdef __SSE2__`. The gcc version of this header, `xmmintrin.h`, and `mmintrin.h` check that the appropriate defines are set before defining anything (are internally guarded). However, the clang versions of these includes are not internally guarded. As a result of this, externally guard the inclusion of these headers. 2021-07-15 David Turner <david@freetype.org> [smooth] Implement Bézier quadratic arc flattening with DDA. Benchmarking shows that this provides a very slighty performance boost when rendering fonts with lots of quadratic Bézier arcs, compared to the recursive arc splitting, but only when SSE2 is available, or on 64-bit CPUs. On a 2017 Core i5-7300U CPU on Linux/x86_64: ftbench -p -s10 -t5 -cb DroidSansFallbackFull.ttf Before: 4.033 us/op (best of 5 runs for all numbers) After: 3.876 us/op ftbench -p -s60 -t5 -cb DroidSansFallbackFull.ttf Before: 13.467 us/op After: 13.385 us/op * src/smooth/ftgrays.c (gray_render_conic): New implementation based on DDA and optionally SSE2. 2021-07-15 David Turner <david@freetype.org> [smooth] Minor speedup to smooth rasterizer. This speeds up the smooth rasterizer by avoiding conditional branches in the hot path. - Define a fixed 'null cell', which will be pointed to whenever the current cell is outside of the current target region. This avoids a `ras.cell != NULL` check in the `FT_INTEGRATE` macro. - Also use the null cell as a sentinel at the end of all `ycells` linked-lists, by setting its x coordinate to `INT_MAX`. This avoids a `if (!cell)` check in `gray_set_cell` as well. - Slightly change the worker struct fields to perform a little less operations during rendering. Example results (on a 2013 Corei5-3337U CPU) out/ftbench -p -s10 -t5 -bc DroidSansFallbackFull.ttf Before: 5.472 us/op After: 5.275 us/op out/ftbench -p -s60 -t5 -bc DroidSansFallbackFull.ttf Before: 17.988 us/op After: 17.389 us/op * src/smooth/ftgrays.c (grat_TWorker): Replace `num_cells` field with `cell_free` and `cell_limit`. (NULL_CELL_PTR, CELL_MAX_X_VALUE, CELL_IS_NULL): New macros. (gray_dump_cells, gray_set_cell, gray_sweep, gray_sweep_direct, gray_convert_glyph_inner, gray_convert_glyph): Updated. 2021-07-15 David Turner <david@freetype.org> [tests] Rewrite download script in Python3. This commit replaces the bash script with a Python script that does the same work, plus avoiding to download anything if the files are already installed with the right content. We now use the first 8 bytes of each file's sha256 hash for the digest. * tests/scripts/download-test-fonts.sh: Removed. * tests/scripts/download-test-fonts.py: New script. * tests/README.md: Updated. 2021-07-15 Alex Richardson <Alexander.Richardson@cl.cam.ac.uk> Support architectures where `long` is smaller than pointers. I am currently trying to compile FreeType for CHERI-extended ISAs (CHERI-RISC-V and Arm's Morello), but I am getting compiler warnings from the `FT_UINT_TO_POINTER` macro. When compiling with the CHERI Clang compiler, not using `uinptr_t` for casts between integers an pointers results in the following `-Werror` build failures: ``` In file included from .../src/truetype/truetype.c:22: .../src/truetype/ttgload.c:1925:22: error: cast from provenance-free integer type to pointer type will give pointer that can not be dereferenced [-Werror,-Wcheri-capability-misuse] node->data = FT_UINT_TO_POINTER( glyph_index ); ^ .../include/freetype/internal/compiler-macros.h:79:34: note: expanded from macro 'FT_UINT_TO_POINTER' ``` * include/freetype/internal/compiler-macros.h (FT_UINT_TO_POINTER): The ISO C standard compliant fix for this would be to use `uintptr_t` from `stdint.h`, but I am not sure if this is supported by the minimum compiler version. Therefore, use the compiler-defined `__UINTPTR_TYPE__` macro (supported in GCC 4.6+ and Clang since about 3.0) before checking for `_WIN64` and falling back to `unsigned long`. 2021-07-13 Oleg Oshmyan <chortos@inbox.lv> [base] Fix `FT_Open_Face`'s handling of user-supplied streams. This was already true (though undocumented) most of the time, but not if `FT_NEW` inside `FT_Stream_New` failed or if the `FT_OPEN_XXX` flags were bad. Normally, `FT_Open_Face` calls `FT_Stream_New`, which returns the user-supplied stream unchanged, and in case of any subsequent error in `FT_Open_Face`, the stream is closed via `FT_Stream_Free`. Up to now, however, `FT_Stream_New` allocates a new stream even if it is already given one by the user. If this allocation fails, the user-supplied stream is not returned to `FT_Open_Face` and never closed. Moreover, the user cannot detect this situation: all they see is that `FT_Open_Face` returns `FT_Err_Out_Of_Memory`, but that can also happen after a different allocation fails within the main body of `FT_Open_Face`, when the user's stream has already been closed by `FT_Open_Face`. It is plausible that the user stream's `close` method frees memory allocated for the stream object itself, so the user cannot defensively free it upon `FT_Open_Face` failure lest it ends up doubly freed. All in all, this ends up leaking the memory/resources used by user's stream. Furthermore, `FT_Stream_New` simply returns an error if the `FT_OPEN_XXX` flags are unsupported, which can mean either an invalid combination of flags or a perfectly innocent `FT_OPEN_STREAM` on a FreeType build that lacks stream support. With this patch, the user-supplied stream is closed even in these cases, so the user can be sure that if `FT_Open_Face` failed, the stream is definitely closed. * src/base/ftobjs.c (FT_Stream_New): Don't allocate a buffer unnecessarily. Move error-handling code to make the control flow more obvious. Close user-supplied stream if the flags are unsupported. `FT_Stream_Open` always sets `pathname.pointer`, so remove the redundant (re)assignment. None of the `FT_Stream_Open...` functions uses `stream->memory`, so keep just one assignment at the end, shared among all possible control flow paths. ('Unsupported flags' that may need a stream closure can be either an invalid combination of multiple `FT_OPEN_XXX` mode flags or a clean `FT_OPEN_STREAM` flag on a FreeType build that lacks stream support.) 2021-07-13 Oleg Oshmyan <chortos@inbox.lv> [base] Reject combinations of incompatible `FT_OPEN_XXX` flags. The three modes are mutually exclusive, and the documentation of the `FT_OPEN_XXX` constants notes this. However, there was no check to validate this in the code, and the documentation on `FT_Open_Args` claimed that the corresponding bits were checked in a well-defined order, implying it was valid (if useless) to specify more than one. Ironically, this documented order did not agree with the actual code, so it could not be relied upon; hopefully, nobody did this and nobody will be hurt by the new validation. Even if multiple mode bits were allowed, they could cause memory leaks: if both `FT_OPEN_STREAM` and `stream` are set along with either `FT_OPEN_MEMORY` or `FT_OPEN_PATHNAME`, then `FT_Stream_New` allocated a new stream but `FT_Open_Face` marked it as an 'external' stream, so the stream object was never released. * src/base/ftobjs.c (FT_Stream_New): Reject incompatible `FT_OPEN_XXX` flags. 2021-07-12 Alex Richardson <Alexander.Richardson@cl.cam.ac.uk> * meson.build: Fix build for other UNIX systems (e.g., FreeBSD). Without this change the build of `unix/ftsystem.c` fails because the `ftconfig.h` header that defines macros such as `HAVE_UNISTD_H` and `HAVE_FCNTL_H` is only being generated for Linux, macOS, and Cygwin systems: ``` .../builds/unix/ftsystem.c:258:32: error: use of undeclared identifier 'O_RDONLY' file = open( filepathname, O_RDONLY ); ``` Instead of hardcoding a list of operating systems for this check, update the logic that decides whether to build the file and set a boolean flag that can be checked instead. 2021-07-12 Werner Lemberg <wl@gnu.org> [autofit] More clean-ups. * src/autofit/afhints.h (AF_GlyphHintsRec): Remove the no longer needed fields `xmin_delta` and `xmax_delta`. * src/autofit/afhints.c (af_glyph_hints_reload), src/autofit/afloader.c (af_loader_load_glyph): Updated. 2021-07-12 Werner Lemberg <wl@gnu.org> Small clean-ups for the last few commits. * include/freetype/fttrace.h (afwarp): Removed. 2021-07-12 David Turner <david@freetype.org> Remove obsolete `AF_Angle` type and related sources. * src/autofit/afangles.c: File removed. Functions related to sorting moved to... * src/autofit/afhints.c (af_sort_pos, af_sort_and_quantize_widths): This file. * src/autofit/afangles.h: File removed. * src/autofit/aftypes.h: Updated. * src/autofit/autofit.c: Updated. * src/autofit/rules.mk (AUTOF_DRV_SRC): Updated. 2021-07-12 David Turner <david@freetype.org> Remove experimental auto-hinting 'warp' mode. This feature was always experimental, and probably never worked properly. This patch completely removes it from the source code, except for a documentation block describing it for historical purposes. * devel/ftoption.h, include/freetype/config/ftoption.h: Remove `AF_CONFIG_OPTION_USE_WARPER`. * include/freetype/ftdriver.h: Document 'warping' property as obsolete. * src/autofit/afwarp.c, src/autofit/afwarp.h: Files removed. * src/autofit/*: Remove any code related to warp mode. 2021-07-12 David Turner <david@freetype.org> Remove experimental 'Latin2' writing system (`FT_OPTION_AUTOFIT2`). This code has always been experimental and was never compiled anyway (`FT_OPTION_AUTOFIT2` does not appear in `ftoption.h` or even any of our build files). * include/freetype/internal/fttrace.h (aflatin2): Removed. * src/autofit/aflatin2.h, src/autofit/aflatin2.c: Files removed. * src/autofit/afloader.c: Remove undocumented hook to activate Latin2 system. * src/autofit/afstyles.h: Remove `ltn2_dflt` style definition. * src/autofit/afwrtsys.h: Remove `LATIN2` writing system definition. * src/autofit/autofit.c: Updated. 2021-07-05 Werner Lemberg <wl@gnu.org> * src/base/ftlcdfil.c (FT_Library_SetLcdGeometry): Fix argument. Reported by Hin-Tak. 2021-07-03 Werner Lemberg <wl@gnu.org> * meson_options.txt: Sort alphabetically; no final full stops. 2021-07-01 Ben Wagner <bungeman@chromium.org> * src/truetype/ttgxvar.c (tt_set_mm_blend): Test `coords`. It is undefined behavior to pass `NULL` to `memcpy`. `coords' is passed to `memcpy` but `TT_Get_MM_Blend` and `TT_Get_Var_Design` explictly call `tt_set_mm_blend` with `coords` as `NULL`. In addition, `TT_Set_MM_Blend` has a similar possible issue. 2021-06-30 Dominik Röttsches <drott@chromium.org> [sfnt] Support PaintScale in 'COLR' v1 parsing. * include/freetype/ftcolor.h (FT_PaintFormat): Renumber values, add `FT_COLR_PAINTFORMAT_SCALE`. (FT_PaintScale): New structure to represent 'PaintScale*' tables. (FT_COLR_Paint): Updated. * src/sfnt/ttcolr.c (FT_PaintFormat_Internal): New enumeration. (read_paint): Parse 'PaintScale' and friends. 2021-06-30 Dominik Röttsches <drott@chromium.org> [sfnt] Handle fonts without layer list in 'COLR' v1. 'COLR' v1 fonts do not necessarily need to have a layer list; for this reason, 'fontTools' recently started generating fonts in a way that drops the layer list if there are no layers in it. This results in the layer list offset becoming zero, which FreeType treated as an invalid table. Fix that and handle the case for layer list offset being 0. This slightly changes how we need to calculate the starting offset for paints. * src/sfnt/ttcolr.c (tt_face_load_colr): Handle case of layer list offset being zero without outright rejecting table. 2021-06-30 Alexei Podtelezhnikov <apodtele@gmail.com> * src/raster/ftraster.c (Render_Single_Pass): Simplify `band_stack'. 2021-06-29 Alexei Podtelezhnikov <apodtele@gmail.com> [raster] Do not skip the second pass without dropout control. The second pass also fixes horizontal lines through the pixel centers. * src/raster/ftraster.c (black_TWorker): Do not use `second_pass'. (Render_Glyph): Skip the second pass only with the appropriate flag. 2021-06-29 Alexei Podtelezhnikov <apodtele@gmail.com> [raster] Handle sub-band stack locally. * src/raster/ftraster.c (black_TWorker): Move `band_stack' from here.. (Render_Single_Pass): ... to here and accept limit arguments. (Render_Glyph): Updated. 2021-06-25 Anurag Thakur <anuthadev@gmail.com> [CI] Introduce linux CI and refactor job names. * .gitlab-ci.yml: Added jobs for building freetype on linux. 2021-06-28 Alexei Podtelezhnikov <apodtele@gmail.com> [raster] Handle Bézier stack locally. * src/raster/ftraster.c (black_TWorker): Move `arcs' from here... (Conic_To, Cubic_To): ... to here to tighten their scope. (Bezier_Up, Bezier_Down): ... Take the current `arc' argument. 2021-06-28 Dominik Röttsches <drott@chromium.org> [sfnt] Improve paint limit checks Paint tables can appear before the `base_glyphs_v1` offset if the font is produced with the layer list before the base glyph list. In this case paint tables can occur after the layer list but before the base glyph list. Checks in the 'COLR' v1 code were rejecting fonts with this layout. Improve these checks by calculating a minimum offset after which paint tables can occur and use that in safety checks. * src/sfnt/ttcolr.c (Colr, tt_face_load_colr): Declare `paint_start_v1` and calculate that as the minimum of the end of layer list and base glyph list. (get_child_table_pointer, read_paint, tt_face_get_paint_layers): Use that in safety checks. 2021-06-28 Alexei Podtelezhnikov <apodtele@gmail.com> [raster] Clean up vertical sweep. * src/raster/ftraster.c (black_TWorker): Replace the current line offset with the pointer and drop the increment. (Function_Sweep_Init): Take values as arguments instead of pointers. (Vertical_Sweep_*, Horizontal_Sweep_Init, Draw_Sweep): Updated. 2021-06-25 Alexei Podtelezhnikov <apodtele@gmail.com> [raster] Make `band_top' local variable. * src/raster/ftraster.c (black_TWorker): Move `band_top' from here... (Render_Single_Pass): ... to here, and refactor. (Render_Glyph): Updated. 2021-06-25 Alexei Podtelezhnikov <apodtele@gmail.com> [raster] Adjust sub-band bisecting limits. We can bisect a band until it is just a single scan line. This might be slow and cause time-outs but if we need to impose limits it should be elsewhere. * src/raster/ftraster.c (Render_Single_Pass): Tweak sub-banding. 2021-06-25 Alexei Podtelezhnikov <apodtele@gmail.com> * src/raster/ftraster.c (Render_Single_Pass): Remove dead code. 2021-06-25 Werner Lemberg <wl@gnu.org> [base] Add trace level to logging output. Some practical debugging work has shown that displaying level X of an `FT_TRACEX` macro in the output of `FT2_DEBUG="... -v"` would be very helpful to find out which trace level should be selected. As an example, we now get output like ``` [ttobjs:2] TTF driver [ttobjs:2] SFNT driver [sfobjs:2] not a font using the SFNT container format [t1objs:2] Type 1 driver [stream:7] FT_Stream_EnterFrame: 14 bytes ``` * include/freetype/internal/ftdebug.h (FT_LOGGING_TAGX): New macro. (FT_LOG): Use it to add the trace level to the logging tag. * include/freetype/internal/fttrace.h (FT_MAX_TRACE_LEVEL_LENGTH): Adjust. * docs/DEBUG: Updated. 2021-06-24 Alexei Podtelezhnikov <apodtele@gmail.com> [smooth, raster] Fix up and align error codes. FT_Render_Glyph picked up FAILURE or 1 returned from the raster function, which became a confusing error code. Instead, return Raster_Overflow in the unlikely event that banding does not help or another meaningful error. * src/smooth/ftgrays.c (gray_convert_glyph_inner, gray_convert_glyph): Use Raster_Overflow when the rendering pool is exhausted and return it if banding does not help. (gray_raster_render): Use Smooth_Err_Ok. * src/raster/ftraster.c (Render_Single_Pass): Return Raster_Overflow if banding does not help or another error code. 2021-06-23 Alexei Podtelezhnikov <apodtele@gmail.com> [smooth, raster] Remove synonymous error macros. * src/smooth/ftgays.c [STANDALONE_]: s/ErrRaster_/Smooth_Err_/. (gray_convert_glyph_inner): Updated accordingly. * src/raster/ftraster.c [STANDALONE_]: Do not abbreviate error macros. (New_Profile, End_Profile, Insert_Y_Turn, Line_Up, Bezier_Up, Decompose_Curve, Draw_Sweep, Render_Single_Pass, ft_black_render): Updated accordingly. 2021-06-22 Dominik Röttsches <drott@chromium.org> [sfnt] s/PaintTransformed/PaintTransform/, s/transformed/transform/. * include/freetype/ftcolor.h (FT_PaintTransformed, FT_PaintFormat, FT_COLR_Paint): Do it to make it harmonize with other names such as 'PaintTranslate'. * src/sfnt/ttcolr.c (read_paint, tt_face_get_paint): Ditto. 2021-06-22 Dominik Röttsches <drott@chromium.org> Move 'COLR' API to `ftcolor.h`. * include/freetype/freetype.h: Cut section layer managament containing 'COLR' v0 and v1 API and move it to `ftcolor.h` as requested by Werner on freetype-devel. * include/freetype/ftcolor.h: Paste that section. 2021-06-19 Werner Lemberg <david@freetype.org> [truetype] Fix integer overflow. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=35312 * src/truetype/ttinterp.c (Ins_JMPR): Use `ADD_LONG`. 2021-06-19 Werner Lemberg <david@freetype.org> [autofit] Prevent hinting if there are too many segments.

While looping to `Again`, the next operation is successful, but -1 is still returned by the function. The fix is to set `error` to 0 appropriately. Fixes #1063. 2021-06-15 David Turner <david@freetype.org> [meson] Add first regression test to FreeType. * tests/README.md: New file that explains how to build and run the tests with the Meson build. * tests/scripts/download-test-fonts.sh: New bash script to download test font files to the `tests/data` folder. * meson.build, meson_options.txt: Add 'tests' option to enable building and running the test programs (disabled by default). * tests/meson.build: New file. * tests/issue-1063/main.c: Simple regression test to exhibit issue 1063. * .gitignore: Ignore the content of the `tests/data` folder for now. 2021-06-12 Alexei Podtelezhnikov <apodtele@gmail.com> [type42] Fix new memory leak. We need to inverse inheritance of FT_GlyphSlot_Internal so that we have a chance to free the rendered bitmap from the parent slot. * src/type42/t42objs.c (T42_GlyphSlot_Init): Remove the internal parts of the child `ttslot' and replace it with the parent structure.

Since 8-bits is enough to represent SDF data we no longer require 16-bits for this purpose. Also, we now normalize the output data to use the entire 8-bit range efficiently. For example: if we use 3.5 format with a spread of 1 we basically only use the starting 5-bits. By normalizing we can use the entire 8-bit range. * include/freetype/freetype.h (FT_Render_Mode): Updated description for `FT_RENDER_MODE_SDF` regarding this change. * include/freetype/ftimage.h (FT_Pixel_Mode): Removed `FT_PIXEL_MODE_GRAY16` since no longer required. * include/freetype/fttypes.h (FT_F6Dot10): Removed since no longer required. * src/sdf/ftsdfrend.c (ft_sdf_render, ft_bsdf_render): Allocate 8-bit bitmap instead of 16-bit buffer. * src/sdf/ftsdfcommon.h (map_fixed_to_sdf): Added function to convert 16.16 distance value to our desired format. * src/sdf/ftsdf.c (sdf_generate_with_overlaps, sdf_generate_bounding_box): Use the new `map_fixed_to_sdf` function and also use 8-bit output buffer. * src/sdf/ftbsdf.c (finalize_sdf): Output to a 8-bit buffer instead of 16-bit buffer. 2021-06-02 Ben Wagner <bungeman@chromium.org> Werner Lemberg <wl@gnu.org> [sfnt] Fix fallout from 2021-05-29 change. * src/sfnt/ttcolr.c (find_base_glyph_record, find_base_glyph_v1_record): Adjust binary search.

While a function pointer may be cast to another function pointer type, it is required to cast the function pointer back to the original function pointer type before calling it. If a parameter is a pointer the exact pointer type is required. Using a pointer to a different underlying type is technically undefined behavior. The wrapper functions `ft_gzip_alloc` and `ft_gzip_free` took `FT_Memory` (a `FT_MemoryRec_*`) instead of `voidpf` (`void*`), so when gzip calls these callbacks through `alloc_func` or `free_func` it invokes undefined behavior. On most platforms this works out as expected, but newer undefined behavior detectors and targets like wasm can detect this and will produce an error. * src/gzip/ftgzip.c (ft_gzip_alloc, ft_gzip_free): Update signatures to exactly match `alloc_func` and `free_func`, respectively. Internally, cast the `void*` opaque pointer to `FT_Memory`. 2021-05-18 Alexei Podtelezhnikov <apodtele@gmail.com> Prioritize the anti-aliasing renderer module. * modules.cfg: Reorder the renderers. * include/freetype/config/ftmodule.h: Ditto. 2021-05-16 Alexei Podtelezhnikov <apodtele@gmail.com> [sfnt] Additional guards on the POST table.

However, it was not resetting the values of the advances and `glyph_index`. Reset the advances and `glyph_index` to zero. 2021-04-02 Ben Wagner <bungeman@chromium.org> [truetype] Prevent glyph program state from persisting. `FDEF` instructions are specified as allowed only in 'prep' or 'fpgm'. FreeType has attempted to prevent their use in the glyph program, but they were still allowed in glyph programs if defined in a function defined in 'prep' or 'fpgm' and called from the glyph program. Similarly, `IDEF` instructions are specified not to be able to modify any existing instruction. FreeType has attempted to prevent their use in the glyph program, but they can still be used like `FDEF`. This change stores the initial bytecode range type and disallows the use of `FDEF` and `IDEF` while running the glyph program. Most other state is copied from the `TT_Size` into the execution context. However, it is possible for a glyph program to use `WS` to write to the storage area or `WCVTP`, `WCVTF`, and `DELTAC[123]` to write to the control value table. Allowing any change to the global state from the glyph program is problematic as the outlines of any given glyph may change based on the order the glyphs are loaded or even how many times they are loaded. There exist fonts that write to the storage area or the control value table in the glyph program, so their use should not be an error. Possible solutions to using these in the glyph program are * ignore the writes; * value-level copy on write, discard modified values when finished; * array-level copy on write, discard the copy when finished; * array-level copy up-front. Ignoring the writes may break otherwise good uses. A full copy up-front was implemented, but was quite heavy as even well behaved fonts required a full copy and the memory management that goes along with it. Value-level copy on write could use less memory but requires a great deal more record keeping and complexity. This change implements array-level copy on write. If any attempt is made to write to the control value table or the storage area when the initial bytecode range was in a glyph program, the relevant array will be copied to a designated storage area and the copy used for the rest of the glyph program's execution. * src/truetype/ttinterp.h (TT_ExecContextRec): New fields `iniRange`, `glyfCvtSize`, `glyfCvt`, `origCvt`, `glyfStoreSize`, `glyfStorage`, and `origStorage`. * src/truetype/ttinterp.c (Modify_CVT_Check): New function to handle `exc->glyfCvt`.

(read_paint): Initialize and track status of insert_root_transform flag. 2021-02-09 Xavier Claessens <xavier.claessens@collabora.com> * meson.build: s/freetype2_dep/freetype_dep/. Many projects (e.g., fontconfig, cairo) hardcode the `freetype_dep` variable name to use FreeType as subproject because that was the variable name in Centricular's Meson port of FreeType. While they should stop hardcoding that variable name, it does not cost us anything to keep using that name to ease transition. 2021-02-09 Xavier Claessens <xavier.claessens@collabora.com> [meson] Fix handling of HarfBuzz library. * meson.build (harfbuzz_dep): Do not fall back to HarfBuzz by default. Otherwise it causes a dependency cycle: cairo => fontconfig => freetype2 => harfbuzz => cairo Meson will still fall back to HarfBuzz subprojects if the `harfbuzz` option is set to `enabled` instead of `auto` and a `subprojects/harfbuzz.wrap` file is present. In that case it is the responsibility of the main project to set the proper options on each subproject to break the dependency cycle. Fixes: #1028. 2021-02-09 Xavier Claessens <xavier.claessens@collabora.com> [meson] Fix dependency lookup and generate `ftconfig.h`. - zlib: If not found on the system, meson can build it as a subproject. We thus never use the (outdated) zlib support that comes with FreeType. Doing so has the additional advantage that the zlib code can be shared with other projects like GLib if both are subprojects of an application. - harfbuzz: Build as a subproject if not found on the system. - 'QUESTION: What if the compiler doesn't support `-D` but uses `/D` instead as on Windows?' Answer: Meson translate arguments for us. - visibility: Replace self-made code with meson-specific solution. * meson.build (ft2_defines): Rewrite logic to set and handle it. (process_header_command): New variable, previously called `ftoption_command`. (ftoption_command, ftconfig_command): New variables. (zlib_option): Removed. (zlib_dep): New variable. (ft2_deps): Updated. (harfbuzz_dep): Updated. (ftconfig_h_in, ftconfig_h): New variables. (ft2_sources): Updated. (ft2_lib): Updated, handle visibility.

This is copied from GStreamer's meson port of FreeType. (ft2_sources): Add both debug and resource file (the latter for Windows only). (ft2_debug_src): Removed. 2021-02-09 Xavier Claessens <xavier.claessens@collabora.com> * meson.build: s/ft2_libtool_version/ft2_pkgconfig_version/. (freetype2_dep): Use it. `ft2_libtool_version` would be the shared library version, not the one we should use in file `freetype2.pc`. 2021-02-09 Xavier Claessens <xavier.claessens@collabora.com> * meson.build: Use `meson.override_dependency`. This is a new meson mechanism to avoid other projects to hard-code the `freetype2_dep` variable name in their build definition. It also ensures that meson does not mix system and subproject versions of FreeType inside of the same project. Also remove outdated TODO because `declare_dependency` was already there. 2021-02-09 Xavier Claessens <xavier.claessens@collabora.com> * meson.build (bzip2_dep): Simplify. We remove `static:false` from `find_library('bz2')`. I don't know whether the previous code was a workaround for an old meson bug, but at least with version >=0.55.0 (which FreeType uses) it picks the shared library when both are available. File `freetype2.pc` still contains the full path to file `libbz2.so` instead of `-lbz2` – that we need to do this is a meson bug even present in the current version (0.57.0). 2021-02-09 Xavier Claessens <xavier.claessens@collabora.com> * meson.build: Set project version. 2021-02-04 Werner Lemberg <wl@gnu.org> [base] Fix Netpbm tracing message. * src/base/ftobjs.c (FT_Render_Glyph_Internal): Don't emit Netpbm warning if there is nothing to output. 2021-02-04 Werner Lemberg <wl@gnu.org> * src/*: Don't use more than one '\n' in `FT_TRACE` and `FT_ERROR`.

The forthcoming 'bsdf' renderer will require bitmaps for processing. * src/base/ftobjs.c (ft_add_renderer, ft_remove_renderer): Remove renderer's glyph format check before adding and removing them. The 'bsdf' renderer will have a format `FT_GLYPH_FORMAT_BITMAP`. 2020-08-16 Anuj Verma <anujv@iitbhilai.ac.in> Add data types required for the forthcoming 'sdf' module. * include/freetype/freetype.h (FT_Render_Mode): Add new render mode `FT_RENDER_MODE_SDF`, which will be used to generate SDF. * include/freetype/ftimage.h (FT_Pixel_Mode): Add new pixel mode `FT_PIXEL_MODE_GRAY16`, which will be the output of the 'sdf' module.

The old code used to divide the darkening amount by em_ratio twice, leading to unnecessarily bold stems on certain fonts with higher units per em (e.g. Inter). This patch fixes it. The return value of af_loader_compute_darkening was also changed to use 16.16 fixed point to get rid of a redundant truncation operation. This should slightly improve the precision, although it's still bottlenecked by the emboldening function, which uses 26.6 fixed point. * src/autofit/afloader.[ch] (af_loader_compute_darkening): Return FT_Fixed.

For formats like PCL XL format 1, class 2 downloaded fonts (where metrics are removed from the TTF header), this causes problems when the hinting program uses the phantom points (misplaced and distorted glyphs) due to the metrics being unset (all zeros). (tt_get_metrics_incr_overrides): Renamed to... (tt_get_metrics_incremental): ... this. Updated caller * include/freetype/ftincrem.h: Update the documentation to make it clearer that `get_glyph_metrics` is to retrieve metrics from a non-standard source, but *not* for the purpose of imposing custom metrics. 2020-12-14 Werner Lemberg <wl@gnu.org> [type42] Pacify static analysis tools (#59682). * src/type42/t42objs.c (T42_Size_Init, T42_GlyphSlot_Init): Avoid warnings about uninitialized variables. 2020-12-07 Werner Lemberg <wl@gnu.org> * builds/unix/configure.raw: Don't set `FT_DEBUG_LOGGING`.

Add `DLG_STATIC' for 'Debug' configuration on 'x64' and 'win32' platforms. (DisableLanguageExtensions): We need to disable the `/Za` option when building 'dlg' with FreeType as 'dlg' strictly follows the C99 standard. Visual C++ produces behaves unexpectedly when compiling a C99 file with `/Za` option enabled. 2020-11-30 Priyesh Kumar <priyeshkkumar@gmail.com> [base] Add public API to change log handling function. * include/freetype/ftlogging.h (FT_Custom_Log_Handler): New function typedef to store the custom callback logging function.

This corresponds to the following commits in the ttfautohint git repository: bb6842bd3bd437b7b4a7921b0376c860f5e73d18 Typo, formatting. d5c91ddb1cb310257a3dfe9a8e20e1fc51335faa Add Medefaidrin script. * src/autofit/afblue.dat: Add blue zone data for Medefaidrin. * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated. * src/autofit/afscript.h: Add Medefaidrin standard characters. * src/autofit/afranges.c, src/autofit/afstyles.h: Add Medefaidrin data. 2020-09-25 Werner Lemberg <wl@gnu.org> Move `scripts/make_distribution_archives.py` to `src/tools`. * scr/tools/scripts/make_distribution_archives.py: (_TOP_DIR, _SCRIPT_DIR): Updated to new location. (main): s/shutils.copyfile/shutils.copy/ to preserve file permissions. (main): Prefix source file paths with `git_dir` while copying files to allow calls of the script from other places than the top-level directory. 2020-09-24 Werner Lemberg <wl@gnu.org> * src/cff/cffgload.c (cff_slot_load): Scale `vertBearingY`. Towards the end of the the function there is a call to `FT_Outline_Get_CBox` that retrieves the glyph bbox in scaled units. That sets `horiBearing{X,Y}` and `vertBearingX` but `vertBearingY` is left alone, and is not scaled. Patch from Eric Muller <emuller@amazon.com>. 2020-09-24 Werner Lemberg <wl@gnu.org> * src/base/ftobjs.c (FT_Load_Glyph): Trace glyph metrics. 2020-09-22 Werner Lemberg <wl@gnu.org> [meson] Move auxiliary scripts to `builds/meson`. Suggested by Alexei. * scripts/*.py: Move meson scripts to... * builds/meson/*.py: ... this new location. * meson.build: Updated. 2020-09-21 David Turner <david@freetype.org> Add python script for building tarballs. * scripts/make_distribution_archives.py: New file. This standalone Python script should be equivalent to running `make dist` with the Make-based build system, with the following minor differences: - Since `make distclean` doesn't always clean up `objs/` properly, `make dist` archives may contain some stale binaries like `objs/.libs/libfreetype.so.6` or others. - `config.guess` and `config.sub` are not updated unless option `--gnu-config-dir=DIR` is used to specify the location of these files. - Some bits of the auto-generated reference documentation may appear in slightly different order, probably due to issues related to mkdocs and docwriter. As an example, the call scripts/make_distribution_archives.py /tmp/freetype2-dist creates the following files under `/tmp/freetype2-dist`: freetype-<version>.tar.gz freetype-<version>.tar.xz ft<winversion>.zip 2020-09-21 Werner Lemberg <wl@gnu.org> * scripts/extract_freetype_version.py: Fix regex typos. 2020-09-21 David Turner <david@freetype.org> Add Meson build project file. Example usage: # Configure Meson build in directory `build-meson` to generate # release binaries comparable to to the ones from the # autotools/make build system. meson setup build-meson \ --prefix=/usr/local \ --buildtype=debugoptimized \ --strip \ -Db_ndebug=true # After configuring the Meson build with the above command, # compile and install to `/usr/local/`; this includes a pkg-config # file. ninja -C build-meson install # Alternatively, compile and install to `/tmp/aa/usr/local/...` # for packaging. DESTDIR=/tmp/aa ninja -C build-meson install # Generate documentation under `build-meson/docs`. ninja -C build-meson docs Library size comparison for stripped `libfreetype.so` generated by all three build systems: - Default build (autotools + libtool): 712 KiB - CMake build (RelWithDebInfo): 712 KiB - Meson build: 712 KiB * meson.build: New top-level Meson build file for the library. * meson_options.txt: New file. It holds user-selectable options for the build, which can be printed with `meson configure`, and selected at `meson setup` or `meson --reconfigure` time with `-D<option>=<value>`. * scripts/parse_modules_cfg.py: A script invoked by `meson.build` to parse `modules.cfg` and extract important information out of it (i.e., the list of modules). * scripts/process_ftoption_h.py: New script invoked by `meson.build` to process the original `ftoption.h` file. It enables or disables configuration macro variables based on the available dependencies. This is similar to what other build systems are using (i.e., Meson's `configure_file()` command is not used here). * scripts/extract_freetype_version.py: New script invoked by `meson.build` to extract the FreeType version number from `<freetype/freetype.h>`. * scripts/extract_libtool_version.py: New script invoked by `meson.build` to extract the libtool `revision_info` data from `builds/unix/configure.raw`, and to generate the corresponding shared library suffix. * scripts/generate_reference_docs.py: New script invoked by `meson.build` to generate the FreeType 2 reference documentation (using the `docwriter` and `mkdocs` packages, which must be already installed). 2020-09-11 Alexei Podtelezhnikov <apodtele@gmail.com> [raster] Improve the second pass (#58373). Besides dropout control the second horizontal sweep is supposed to clean up straight horizontal edges that are mishandled by the first vertical sweep when a line passes through pixel centers. This line would present as perfectly aligned span edges in the second sweep. * src/raster/ftraster.c (Horizontal_Sweep_Span): Replace the old implementation with a better one focusing on aligned span edges only. 2020-09-08 Alexei Podtelezhnikov <apodtele@gmail.com> [raster] Tune SMART macro (#58352). Windows seems to perform smart dropout control at 26.6 precision. To mimick Windows independent of increased precision, we need to tweak the macro so that some close calls break down rather than up. * src/raster/ftraster.c (SMART): Tweak the macro. 2020-09-08 Alexei Podtelezhnikov <apodtele@gmail.com> [raster] Introduce SMART macro. * src/raster/ftraster.c (SMART): New macro for smart dropout rounding.

Note that on ELF systems, all internal functions have hidden visibility, which avoids the need to enforce this when invoking the compiler (e.g., with an option like `-fvisibility=hidden'). (FT_FUNCTION_DECLARATION, FT_FUNCTION_DEFINITION): New base macros to deal with C and C++ linkage issues at the same time. (FT_LOCAL, FT_LOCAL_DEF, FT_LOCAL_ARRAY, FT_LOCAL_ARRAY_DEF, FT_BASE, FT_BASE_DEF, FT_EXPORT_VAR, FT_BASE_CALLBACK, FT_BASE_CALLBACK_DEF): Redefined using new macros. 2020-07-05 David Turner <david@freetype.org> [build] Split off more stuff from `ftconfig.h'. * builds/unix/ftconfig.h.in, builds/vms/ftconfig.h, include/freetype/config/ftconfig.h: Split off macro definitions required by the FreeType API headers to... * include/freetype/config/public-macros.h: ...this new file. * builds/unix/ftconfig.h.in, builds/vms/ftconfig.h, include/freetype/config/ftconfig.h: Split off macro definitions used by the library but not to be exposed to clients to... * include/freetype/config/compiler-macros.h: ...this new file. * include/freetype/internal/*.h, src/raster/ftraster.h: Include `compiler-macros.h' where needed. 2020-07-05 David Turner <david@freetype.org> [build] Move mac support code to `mac-support.h'. * builds/unix/ftconfig.h.in, builds/vms/ftconfig.h, include/freetype/config/ftconfig.h: Split off mac-specific stuff to... * include/freetype/config/mac-support.h: ...this new file. * CMakeLists.txt, builds/unix/configure.raw: Remove `/undef -> #undef' string replacement; the affected code is no longer part of the `ftconfig.h' template. 2020-07-05 David Turner <david@freetype.org> [build] Put integer type definitions into `integer-types.h'. Refactor some of the `ftconfig.h' headers and template to move the definition of the FreeType integer types (e.g., `FT_Int16') to a common header file `freetype/config/integer-types.h'. * builds/unix/ftconfig.h.in, builds/vms/ftconfig.h, include/freetype/config/ftconfig.h: Split off integer type definition stuff to... * include/freetype/config/integer-types.h: ...this new file. * builds/unix/ftconfig.h.in: Control the definition of `FT_SIZEOF_INT' and `FT_SIZEOF_LONG' with macro `FT_USE_AUTOCONF_SIZEOF_TYPES'. If these are not defined, auto detection happens in `integer-types.h' as usual based on `INTXX_MAX' values. Otherwise the autoconf-detected values are used. * builds/unix/configure.raw (CPPFLAGS): Don't include path to `config' directory. Instead, ... (FT_CONFIG_STANDARD_LIBRARY_H): Use complete path. 2020-07-05 David Turner <david@freetype.org> [build] Rename `build/unix/ftconfig.in' to `ftconfig.h.in'. Since we are no longer limited to 8.3 file names, it is simpler to follow the usual conventions for template files. * builds/unix/ftconfig.in: Renamed to... * builds/unix/ftconfig.h.in: ...this. * CMakeLists.txt, builds/unix/configure.raw: Updated. 2020-07-03 Alexei Podtelezhnikov <apodtele@gmail.com> [smooth] Introduce direct oversampling for overlaps. This implements oversampling to mitigate artifacts in pixels partially covered by overlapping contours. It turns out that the 4x4 oversampling is sufficient but, at least, quadruples the rendering time. The outline has to set FT_OUTLINE_OVERLAP to use this method. * include/freetype/ftimage.h (FT_OUTLINE_OVERLAP): New flag. * src/smooth/ftsmooth.c (ft_smooth_render): Check it to... (ft_smooth_raster_overlap): ... inflate outline and set up direct rendering for oversampling with... (ft_smooth_overlap_spans): ... new span function that integrates them. 2020-07-03 Alexei Podtelezhnikov <apodtele@gmail.com> [smooth] Use direct rendering mode in Harmony. Instead of rendering 3 bitmaps side by side and reshuffling, we use direct rendering to deliver the bitmaps on each third byte. * src/smooth/ftsmooth.c (ft_smooth_raster_lcd) [!FT_CONFIG_OPTION_SUBPIXEL_RENDERING]: Set up direct mode with... (ft_smooth_lcd_spans): ... new span function. 2020-07-03 Alexei Podtelezhnikov <apodtele@gmail.com> [smooth] Separate LCD paths from gray rendering. This makes `ft_smooth_render' a lot smaller and easier to follow. It also cleanly separates Harmony and ClearType-style LCD rendering algorithms. Now I only wish to move LCD filtering and geometry from FT_Library to FT_Renderer. * src/smooth/ftsmooth.c (ft_smooth_render): Move LCD code from here... (ft_smooth_raster_lcd, ft_smooth_raster_lcdv): ... to here. [FT_CONFIG_OPTION_SUBPIXEL_RENDERING]: Reorganize #ifdef's. 2020-06-20 Sebastian Rasmussen <sebras@gmail.com> [cff] Fix handling of `style_name == NULL' (#58630). * src/cff/cffobjs.c (cff_face_init): If a call to `cff_strcpy' fails by returning NULL in `cff_face_init', `remove_style' is still called. This means that the NULL pointer is dereferenced, causing a crash. 2020-06-19 Sebastian Rasmussen <sebras@gmail.com> [cff] Fix another two memory leaks (#58629). * src/cff/cffobjs.c (cff_size_init): If a call to `funcs->create' fails to allocate one of the `internal->subfont' variables, make sure to free `internal->topfont' and any successfully allocated subfonts. 2020-06-19 Sebastian Rasmussen <sebras@gmail.com> [psaux] Fix memory leak (#58626). * src/psaux/psstack.c (cf2_stack_init): If `cf2_stack_init' fails to allocate the stack, return error early. 2020-06-19 Sebastian Rasmussen <sebras@gmail.com> [base] Fix memory leak (#58624). * src/base/ftobjs.c (FT_New_Size): Avoid trying to free `size->internal' unless `size' has been allocated. This mistake appeared in the fix for issue #58611. 2020-06-19 Alexei Podtelezhnikov <apodtele@gmail.com> [base] Rework d1180b5f9598 until further notice. * src/base/ftoutln.c (FT_Outline_Get_Orientation): Reject large outlines. 2020-06-19 Sebastian Rasmussen <sebras@gmail.com> [cff, cid] Fix segfaults in case of error (#58621). * src/cff/cffobjs.c (cff_slot_done), src/cid/cidobjs.c (cid_slot_done): If `ft_glyphslot_init' fails to allocate `internal', then the class' `done_slot' callback (called by `ft_glyphslot_done') must not dereference the pointer to `internal'. 2020-06-19 Werner Lemberg <wl@gnu.org> [base] Fix UBSAN error. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=23166 * src/base/ftoutln.c (FT_Outline_Get_Orientation): Avoid values larger than 32 bits. 2020-06-19 Werner Lemberg <wl@gnu.org> [woff2] Fix segfault.

Do the same for both allocations if there is a later error. 2020-06-13 Werner Lemberg <wl@gnu.org> Remove redundant inclusion of `ft2build.h'. * */*: Remove `#include <ft2build.h>' where possible. * include/freetype/freetype.h: Remove cpp error about missing inclusion of `ft2build.h'. 2020-06-08 David Turner <david@freetype.org> Make macros for header file names optional. We no longer have to take care of the 8.3 file name limit; this allows us (a) to introduce longer, meaningful file names, and (b) to avoid macro names in `#include' lines altogether since some compilers (most notably Visual C++) doesn't support this properly. */*: Replace #include FOO_H with #include <freetype/foo.h> or something similar. Also update the documentation. 2020-06-02 Werner Lemberg <wl@gnu.org> * src/sfnt/ttcmap.c (tt_face_build_cmaps): Trace number of cmaps. 2020-05-18 David Turner <david@freetype.org> Remove obsolete HAVE_STDINT_H probing macro. This macro was updated by the unix configure script and the `CMakeLists.txt' one, but is never used in the source tree (nor is <stdint.h> included anywhere). * CMakeLists.txt, builds/unix/ftconfig.in: Don't handle `HAVE_STDINT_H'. 2020-05-18 David Turner <david@freetype.org> Remove Jamfile files from the tree. These have not been used in a very, very long time, so better remove them. A corresponding patch will be submitted to the `freetype2-demos' repository. * src/Jamfile, src/*/Jamfile, Jamrules: Delete. 2020-05-12 Alexei Podtelezhnikov <apodtele@gmail.com> [smooth] Turn on LCD filtering during FreeType initialization. * src/smooth/ftsmooth.c (ft_smooth_init): Enable LCD filtering. * include/freetype/ftlcdfil.h: Document it, remove patent warnings. * include/freetype/freetype.h (FT_Render_Mode): Updated. * include/freetype/config/ftoption.h, devel/ftoption.h [FT_CONFIG_OPTION_SUBPIXEL_RENDERING]: Do not mention patents. 2020-05-11 Alexei Podtelezhnikov <apodtele@gmail.com> [smooth] Stop using dedicated LCD modules and classes. The LCD modules were never truly independent. They mostly served as a way to disable patented LCD rendering, which is no longer necessary. The `smooth' module now handles LCD modes as well. * src/smooth/ftsmooth.c (ft_smooth_lcd_renderer_class. ft_smooth_lcdv_renderer_class): Deleted. (ft_render_smooth): Reworked from `ft_render_smooth_generic'. * src/smooth/ftsmooth.h: Remove dedicated LCD classes. * src/smooth/module.mk: Remove dedicated LCD modules. * include/freetype/config/ftmodule.h: Ditto. * builds/amiga/include/config/ftmodule.h: Ditto. * include/freetype/ftmodapi.h: Do not mention LCD modules. 2020-05-09 Werner Lemberg <wl@gnu.org> * Version 2.10.2 released. ========================== Tag sources with `VER-2-10-2'. * docs/VERSION.TXT: Add entry for version 2.10.2. * README, Jamfile (RefDoc), src/base/ftver.rc, builds/windows/vc2010/index.html, builds/windows/visualc/index.html, builds/windows/visualce/index.html, builds/wince/vc2005-ce/index.html, builds/wince/vc2008-ce/index.html, docs/freetype-config.1: s/2.10.1/2.10.2/, s/2101/2102/. * include/freetype/freetype.h (FREETYPE_PATCH): Set to 2. * builds/unix/configure.raw (version_info): Set to 23:2:17. * CMakeLists.txt (VERSION_PATCH): Set to 2. * docs/CHANGES: Updated. 2020-05-08 Jakub Alba <jalba@vewd.com> * src/truetype/ttinterp.c (TT_RunIns): Adjust loop counter (#58319). The font that exceeds the old limit is Icono Regular, version 1.00000. 2020-05-03 Alexei Podtelezhnikov <apodtele@gmail.com> * builds/freetype.mk: Refactor for readability. 2020-05-02 Alexei Podtelezhnikov <apodtele@gmail.com> [builds] Clean up Windows CE project files.

In order to support `gzip' encoded header the call to `inflateInit2' was modified in commit 6a92b1fadde26477a9179. However, this code breaks with the outdated internal version of zlib. This is a temporary fix to conditionally support `gzip' encoded header whenever a system installation of zlib is being used. Problem report in https://lists.nongnu.org/archive/html/freetype-devel/2020-02/msg00023.html * src/gzip/ftgzip.c (FT_Gzip_Uncompress): Change the the call to `inflateInit2' depending on whether the system installation is being used or the internal copy. 2020-02-29 Ben Wagner <bungeman@google.com> [truetype] Fix state of `FT_Face' for buggy `gvar' tables (#57923). By resetting the blend as implemented with this commit fonts with invalid `gvar' tables may keep calling into `ft_var_load_gvar' from `tt_set_mm_blend' and failing, but the font was invalid anyway and we want to keep seeing the failure in `tt_set_mm_blend'. * src/truetype/ttgxvar.c (ft_var_load_gvar): Calculate length of offset array once. Allocate arrays after `FT_FRAME_ENTER' (extra check before allocating and avoid needing to free array later if error entering frame). Always call `FT_FRAME_EXIT'. Consistently set counts immediately after array initialized. Reset the blend (particularly `blend->glyphoffsets') on failure. 2020-03-01 Nikhil Ramakrishnan <ramakrishnan.nikhil@gmail.com> [docs] Update docwriter stylesheet. This change is required to support docwriter 1.2.1. See https://github.com/freetype/docwriter/issues/36 for more information. * docs/markdown/stylesheets/extra.css: (.md-typeset code) -> (.md-typeset pre>code) (pre) -> (pre>code) (p, .md-typeset p, h4): Remove commented styles.

Also do some sanitizing to avoid a too early exit. (TT_Vary_Apply_Glyph_Deltas): Improve tracing message. 2020-02-27 Werner Lemberg <wl@gnu.org> Make `FT_HAS_*' and `FT_IS_*' really return true (#57906). * include/freetype/freetype.h (FT_HAS_*, FT_IS_*): Implement it. 2020-02-25 Dominik Röttsches <drott@chromium.org> Fix for CFF space glyph regression (#57541). * src/psaux/psft.c (cf2_decoder_parse_substrings): Replace early-out with FT_OFFSET. 2020-02-22 Werner Lemberg <wl@gnu.org> [woff2] Fix font table access.

Adjust tracing levels for comments, and more formatting. 2019-08-27 Nikhil Ramakrishnan <ramakrishnan.nikhil@gmail.com> [woff2] Support `hmtx' reconstruction when `glyf' is untransformed. `reconstruct_hmtx' requires `info->x_mins' and `info->num_glyphs' to reconstruct the hmtx table. In case glyf is not transformed, we call `get_x_mins' which does the necessary work. * src/sfnt/sfwoff2.c (get_x_mins): New function. (reconstruct_font): Call get_x_mins. 2019-08-27 Nikhil Ramakrishnan <ramakrishnan.nikhil@gmail.com> [sfnt] Support `face->num_faces' for WOFF2 fonts. Set correct value of `face->num_faces' for WOFF2 fonts. This is being handled separately because we only load the tables for the requested font face in `woff2_open_font' and create a single-face sfnt stream. The full discussion is at: https://lists.gnu.org/archive/html/freetype-devel/2019-08/msg00000.html * src/sfnt/sfobjs.c (sfnt_open_font): Add parameter `woff2_num_faces'.

Free up memory after use, and improve error handling. * src/sfnt/sfwoff2.c (reconstruct_font, woff2_open_font): Implement changes. 2019-08-27 Nikhil Ramakrishnan <ramakrishnan.nikhil@gmail.com> [woff2] Avoid too many calls to `FT_REALLOC'. We do this by using `totalSfntSize' as an initial reference, and extending the buffer when required. This reduces rendering time considerably. * include/freetype/internal/wofftypes.h (WOFF2_HeaderRec): Add `totalSfntSize', rename `total_sfnt_size' to `actual_sfnt_size'. * src/sfnt/sfwoff2.c (write_buf): Add parameter `dst_size' to keep track of and update total size of stream. (WRITE_SFNT_BUF, WRITE_SFNT_BUF_AT): Modify macros accordingly. (pad4, store_loca, reconstruct_glyf, reconstruct_hmtx, reconstruct_font): Update parameters to accept `sfnt_size'. (woff2_open_font): Add variable `sfnt_size'. Use WOFF2 header field `totalSfntSize' as initial reference (if value makes sense) and allocate `totalSfntSize' bytes for the sfnt stream. `write_buf' handles reallocation if and when required. Also resize the stream to `actual_sfnt_size' after reconstruction. 2019-08-27 Nikhil Ramakrishnan <ramakrishnan.nikhil@gmail.com> [woff2] Reconstruct `loca', `hmtx', and swap out stream. Add necessary functions to reconstruct loca and hmtx tables (the two remaining tables that can have a transform). `woff2_open_font' is now capable of loading a woff2 font face. This code may still need more refining and better memory management. * include/freetype/internal/wofftypes.h (WOFF2_HeaderRec): Add total (final) size of sfnt stream. (WOFF2_InfoRec): Add header checksum value. * src/sfnt/sfobjs.c (sfnt_open_font): Change `face_instance_index' parameter to its pointer so its value can be modified by `woff2_open_font'. * src/sfnt/sfwoff2.c: (WRITE_SFNT_BUF_AT): New macro to write into sfnt buffer at given position. (write_buf): Add parameter `extend_buf' which allows caller to specify whether buffer should be reallocated before copying data. (WRITE_SFNT_BUF): Updated. (pad4, store_loca, reconstruct_htmx): New functions. (reconstruct_glyf): Calculate loca values and store them. (reconstruct_font): Call `reconstruct_hmtx', write table record entries, and calculate table checksums. Also calculate font checksum and update `checksumAdjustment' entry in head table. (woff2_open_font): Open stream for sfnt buffer, swap out input stream and return. * src/sfnt/sfwoff2.h (woff2_open_font): Modify parameter to accept pointer to `face_index'. 2019-08-27 Nikhil Ramakrishnan <ramakrishnan.nikhil@gmail.com> [woff2] Reconstruct transformed `glyf' table. Reconstruct `glyf' table if it is transformed in the uncompressed table stream. Also add necessary structures, macros and functions. * include/freetype/internal/wofftypes.h (WOFF2_InfoRec, WOFF2_SubstreamRec, WOFF2_PointRec): New structures. (WOFF2_TableRec): s/OrigLength/dst_length/. * src/sfnt/sfwoff2.c (READ_255USHORT, READ_BASE128): Use `FT_SET_ERROR' to set implicit `error' variable. (WRITE_SHORT): New macro. (N_CONTOUR_STREAM, N_POINTS_STREAM, FLAG_STREAM, GLYPH_STREAM, COMPOSITE_STREAM, BBOX_STREAM, INSTRUCTION_STREAM): New macros to refer to substreams of the transformed `glyf' tables. (Read255UShort, ReadBase128): Return errors set by `FT_READ_XXX' macros. (with_sign, safe_int_addition): New functions to add sign to values based on a flag and perform safe addition respectively. (triplet_decode): Decode variable-length (flag, xCoordinate, yCoordinate) triplet for a simple glyph. See https://www.w3.org/TR/WOFF2/#triplet_decoding (store_points, compute_bbox, composteGlyph_size, reconstruct_glyf): New functions. (reconstruct_font): Call `reconstruct_glyf'. * src/sfnt/sfwoff2.h: Add required constants. * src/sfnt/woff2tags.h: Move out constants to `sfwoff2.h'. 2019-08-27 Nikhil Ramakrishnan <ramakrishnan.nikhil@gmail.com> [woff2] Copy un-transformed tables to sfnt stream. Copy un-transformed tables to the sfnt stream. * src/sfnt/sfwoff2.c: (WRITE_SFNT_BUF): New macro. (write_buf): New function. Extend memory of `dst' buffer and copy bytes from `src'. (compute_ULong_sum): New function. Calculate checksum of table. (reconstruct_font): Change `FT_Byte* sfnt' to `FT_Byte** sfnt_bytes'. This has been done because we reallocate memory to `sfnt' multiple times, which may change the pointer value of `sfnt'. This new pointer must be propogated back to the caller. Same reason for using a double pointer in `write_buf'. * src/sfnt/woff2tags.h (WOFF2_DEFAULT_MAX_SIZE): New macro used for overflow checking. 2019-08-27 Nikhil Ramakrishnan <ramakrishnan.nikhil@gmail.com> [woff2] Create stream for uncompressed buffer. Uncompressed buffer is now an `FT_Stream'. Perform basic checks and start iterating over tables. * src/sfnt/sfwoff2.c (stream_close, find_table, read_num_hmetrics): New functions. (reconstruct_font): Modify parameters and iterate over tables. (woff2_open_font): Updated. 2019-08-27 Nikhil Ramakrishnan <ramakrishnan.nikhil@gmail.com> [woff2] Handle TTCs and start reconstructing font. We `handle' TTCs by modifying the `indices' array to point to only those tables that are part of the requested `face_index'. Set and use `num_tables' in `WOFF2_TtcFont'. * src/sfnt/sfwoff2.c (reconstruct_font): New function. (woff2_open_font): Start reconstruction of font. 2019-08-27 Nikhil Ramakrishnan <ramakrishnan.nikhil@gmail.com> [woff2] Get known tags from function. Change `KnownTags' to a function (`woff2_known_tags'). This avoids introducing a global constant array. This function returns the specified index without *any* checks. The caller must ensure that `index' is within array limits. * src/sfnt/sfwoff2.c (woff2_open_font): Change `KnownTags[...]' notation to `woff2_known_tags( ... )'. * src/sfnt/woff2tags.c: Perform changes. * src/sfnt/woff2tags.h: Update definitions. 2019-08-27 Nikhil Ramakrishnan <ramakrishnan.nikhil@gmail.com> [woff2] Minor. * src/sfnt/sfwoff2.c (woff2_uncompress): Add error message (woff2_open_font): Free `uncompressed_buf'. 2019-08-27 Nikhil Ramakrishnan <ramakrishnan.nikhil@gmail.com> [woff2] Uncompress Brotli streams and `face_index' support. WOFF2 compressed stream is now uncompressed if Brotli is available. This data is stored in a separate buffer (uncompressed_buf) because it does not contain direct table data. Certain tables have transformations applied to them, and they must be reconstructed before we can write those tables to the SFNT stream. `face_index' is now being passed as a parameter to `woff2_open_font'. * src/sfnt/sfobjs.c (sfnt_open_font): Add parameter `face_instance_index'. * src/sfnt/sfwoff2.c (woff2_uncompress): New function. (woff2_open_font): Call `woff2_uncompress'. (compute_first_table_offset): Fix return type. * src/sfnt/sfwoff2.h (woff2_open_font): Modify declaration. 2019-08-27 Nikhil Ramakrishnan <ramakrishnan.nikhil@gmail.com> * builds/unix/configure.raw: Change argument name to `brotli'. 2019-08-27 Nikhil Ramakrishnan <ramakrishnan.nikhil@gmail.com> Add Brotli dependency and required checks. Brotli is required for decompressing WOFF2 font directory streams. The library is thus being added as an optional dependency for FreeType. * builds/unix/configure.raw: Add checks for `libbrotlidec'. (REQUIRES_PRIVATE, LIBS_PRIVATE, LIBSSTATIC_CONFIG): Updated. * devel/ftoption.h, include/freetype/config/ftoption.h (FT_CONFIG_OPTION_USE_BROTLI): New macro. 2019-08-27 Nikhil Ramakrishnan <ramakrishnan.nikhil@gmail.com> [woff2] Write SFNT Offset table. * src/sfnt/sfwoff2.c (WRITE_USHORT, WRITE_ULONG): New macros.

The same as previous commit but for the old engine. * src/psaux/t1decode.c (t1operator_seac): Implement it. 2019-07-04 Chris Liddell <chris.liddell@artifex.com> [psaux] (1/2) Handle fonts that use SEAC for ligatures (#56580). As originally intended, a Type 1 SEAC charstring would be used for an accented glyph (like `acaron' or `uumlaut'), where the advance width of the SEAC glyph is the same as that of the `base' glyph (like `a' or `u'). In this case it is not uncommon for the SEAC glyph to not use an (H)SBW opcode of its own but to rely on the value from the base glyph. However, out-of-spec fonts also use SEAC glyphs for ligatures (like `oe' or `fi'), and in those cases the overall advance width is greater than that of the `base' glyph.

Update copyright notices. 2019-04-29 Alexei Podtelezhnikov <apodtele@gmail.com> [smooth] Simplify cubic Bézier flattening. The previous implementation is correct but it is too complex. The revised algorithm is based on the fact that each split moves the control points closer to the trisection points on the chord. The corresponding distances are good surrogates for the curve deviation from the straight line. This cubic flattening algorithm is somewhat similar to the conic algorithm based the distance from the control point to the middle of the chord. The cubic distances, however, decrease less predictably but are easy enough to calculate on each step. The new algorithm produces slightly larger number of splits, which is compensated by its simplicity. The overall rendering performance is improved by 1-2%. The larger number of splits does not necessarily result in higher quality, which stays comparable. * src/smooth/ftgrays.c (gray_render_cubic): Replace the split condition. 2019-04-26 Alexei Podtelezhnikov <apodtele@gmail.com> [smooth] Bithacks and cosmetics. * src/smooth/ftgrays.c (gray_record_cell, gray_set_cell, gray_hline, gray_render_conic, gray_convert_glyph_inner): Updated. 2019-04-25 Alexei Podtelezhnikov <apodtele@gmail.com> Optimize Bézier bisections.

Before this commit we had code like (FT_Bool)( globals->glyph_styles[gindex] & 0x8000) Since `FT_Bool' is defined to be an `unsigned char', the code evaluated to something like (unsigned char)( 0x8532 & 0x8000) which in turn expanded to (unsigned char)( 0x8000) and finally yielded 0x00 – i.e., false – not as expected.

For bitmap fonts, `FT_Load_Glyph' should either return an error or not set the format to `FT_GLYPH_FORMAT_OUTLINE'. However, in this case `FT_Load_Glyph' calls into the auto-hinter which calls back into `FT_Load_Glyph' with `FT_LOAD_NO_SCALE' in the flags, which marks the glyph as `FT_GLYPH_FORMAT_OUTLINE' with an empty path (even though it doesn't have any path). It appears that the auto-hinter should not be called when the face doesn't have outlines. The current test for using the auto-hinter in `FT_Load_Glyph' checks whether the driver supports scalable outlines, but not if the face supports scalable outlines. * src/base/ftobjs.c (FT_Load_Glyph): Directly check whether we have scalable outlines. 2018-09-21 Werner Lemberg <wl@gnu.org> [raster] Fix disappearing vertical lines (#54589). * src/raster/ftraster.c (Vertical_Sweep_Span): Handle special case where both left and right outline exactly pass pixel centers. 2018-09-20 Alexei Podtelezhnikov <apodtele@gmail.com> * src/base/ftobjs.c (ft_glyphslot_preset_bimap): Tiny rounding tweak.

PCF comes with charmap lookup table, aka PCF encodings.

Also avoid calling `tt_get_metrics' twice under some circumstances. 2018-08-26 Werner Lemberg <wl@gnu.org> Various minor clean-ups. * src/base/ftapi.c: Remove.

This commit enables OpenType's COLR/CPAL table handling; a typical application are color emojis that can be scaled to any size. If the color palette does not exist or is invalid, the rendering step rasterizes the outline instead. The current implementation assumes that the foreground is black.

AC_COMPILE_IFELSE only tries to compile a `*.c' to a `*.o'. The Solaris Studio 12.1 through 12.5 compilers see the `-fvisibility=hidden' flag, but ignore it with a warning of: cc: Warning: Option -fvisibility=hidden passed to ld, if ld is invoked, ignored otherwise AC_LINK_IFELSE does the compile and then tries to link the result, at which point the Solaris linker will issue an error: ld: fatal: option '-fvisibility=hidden' is incompatible with building a dynamic executable If we don't use AC_LINK_IFELSE to catch the error, then configure will fail further tests which attempt to link, such as those testing dependencies like `libbz2'. Also, don't try adding `-fvisibility' if we have already added `-xldscope', just use one of them, since Sun Studio 12 and earlier compilers only issue a warning, and don't try passing through to the linker to generate an error, so AC_LINK_IFELSE doesn't catch them.

Instead, make those functions no-ops; the calling functions will provide a pointer to a buffer instead. * src/autofit/afcjk.c (af_cjk_metrics_init_widths, af_cjk_metrics_init_blues, af_cjk_metrics_check_digits), src/autofit/aflatin.c (af_latin_metrics_init_widths, af_latin_metrics_init_blues, af_latin_metrics_check_digits) [!FT_CONFIG_OPTION_USE_HARFBUZZ]: Use pointer to local variable for `shaper_buf'. 2018-05-07 Nikolaus Waxweiler <madigens@gmail.com> [cmake] Allow using project as subfolder in other project. * CMakeLists.txt: Test for CMake build directory being different from source directory. Provide other parts of the build system access the full include directory. 2018-05-07 Werner Lemberg <wl@gnu.org> [build] Suppress configure's `nothing to be done' message. This is due to calling the configure script via `make' (within the top-level `configure' wrapper script). The same can happen for all other secondary make targets that are used to only modify the primary one, e.g., `make setup devel'. * builds/dos/detect.mk (emx, turboc, watcom, borlandc, borlandc16), builds/os2/detect (visualage, watcom, borlandc, devel), builds/unix/detect.mk (devel, lcc, unix), builds/windows/detect.mk (visualc, watcom, visualage, lcc, mingw32, bcc32, devel-bcc, devel-gcc): Use no-op recipe. 2018-05-04 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> Support symbol visibility features of Sun / Oracle C compilers. Reported by Kiyoshi Kanazawa: https://lists.gnu.org/archive/html/freetype-devel/2018-05/msg00008.html Thanks to the suggestions by Alexei and Alan Coopersmith. * builds/unix/configure.raw: Check if "-xldscope=hidden" is accepted, and if so, it is added to CFLAGS. This is the option making Sun / Oracle C compilers hide the symbols from global scope. * include/freetype/config/ftconfig.h: Use "__global" prefix for FT_EXPORT() macro, if SunPro C is newer than Sun ONE Studio 8 (2003). * builds/unix/ftconfig.in: Ditto. * builds/vms/ftconfig.h: Ditto. 2018-05-02 Nikolaus Waxweiler <madigens@gmail.com> Unbreak CMake Windows installation * CMakeLists.txt: Generate ftconfig.h on non-UNIX. 2018-05-02 Werner Lemberg <wl@gnu.org> Remove FT_CONFIG_OPTION_PIC and related code. */* [FT_CONFIG_OPTION_PIC]: Remove all code guarded by this preprocessor symbol. */*: Replace `XXX_GET' macros (which could be either a function in PIC mode or an array in non-PIC mode) with `xxx' arrays. * include/freetype/internal/ftpic.h, src/autofit/afpic.c, src/autofit/afpic.h, src/base/basepic.c, src/base/basepic.h, src/base/ftpic.c, src/cff/cffpic.c, src/cff/cffpic.h, src/pshinter/pshpic.c, src/pshinter/pshpic.h, src/psnames/pspic.c, src/psnames/pspic.h, src/raster/rastpic.c, src/raster/rastpic.h, src/sfnt/sfntpic.c, src/sfnt/sfntpic.h, src/smooth/ftspic.c, src/smooth/ftspic.h, src/truetype/ttpic.c, src/truetype/ttpic.h: Removed. ---------------------------------------------------------------------------- Copyright (C) 2018-2022 by David Turner, Robert Wilhelm, and Werner Lemberg.

Remove a redundant parenthesis. 2006-05-10 Werner Lemberg <wl@gnu.org> * builds/unix/ftsystem.c (FT_Stream_Open): Avoid infinite loop if given an empty, un-mmap()able file. Reported and suggested fix in Savannah bug #16555. * builds/freetype.mk (refdoc): Write-protect the `docmaker' directory to suppress generation of .pyc files. According to the Python docs there isn't a more elegant solution (currently). * builds/toplevel.mk (dist): New target which builds .tar.gz, .tar.bz2, and .zip files. Note that the version number is still hard-coded. (do-dist): Sub-target of `dist'. (CONFIG_GUESS, CONFIG_SUB): New variables. (.PHONY): Updated. 2006-05-09 Rajeev Pahuja <rpahuja@esri.com> * builds/win32/visualc/freetype.sln, builds/win32/visualc/freetype.vcproj: Upgraded to VS.NET 2005 from VS.NET 2003 Added files ftbbox.c, fttype1.c, ftwinfnt.c, ftsynth.c. * builds/win32/visualc/index.html: Updated. 2006-05-07 Werner Lemberg <wl@gnu.org> Put version information into the configure script. Reported by Paul Watson <pwatson@redlinepy.com>. * builds/unix/configure.ac: Renamed to... * builds/unix/configure.raw: This which now serves (with appropriate modifications) as a template for configure.ac. * version.sed: New script. * autogen.sh: Generate configure.ac from configure.raw, using FREETYPE_MAJOR, FREETYPE_MINOR, and FREETYPE_PATCH from freetype.h. 2006-05-06 Werner Lemberg <wl@gnu.org> * include/freetype/freetype.h (FREETYPE_PATCH): Set to 1. * builds/unix/configure.ac (version_info): Set to 9:10:3. * builds/win32/visualc/index.html, builds/win32/visualc/freetype.dsp, builds/win32/visualc/freetype.vcproj, builds/freetype.mk (refdoc), Jamfile (RefDoc), README: s/220/221/, s/2.2.0/2.2.1/. Minor updates. * docs/CHANGES, docs/VERSION.DLL, docs/PROBLEMS, README.CVS: Updated. * builds/unix/install-sh: Updated from `texinfo' CVS module at savannah.gnu.org. * devel/ftoption.h: Synchronize with include/freetype/config/ftoption.h. 2006-05-04 Werner Lemberg <wl@gnu.org> * src/lzw/ftlzw2.c: Renamed to... * src/lzw/ftlzw.c: This. * src/lzw/Jamfile, src/lzw/rules.mk: Updated. * builds/mac/FreeType.m68k_cfm.make.txt, builds/mac/FreeType.m68k_far.make.txt, builds/mac/FreeType.ppc_carbon.make.txt, builds/mac/FreeType.ppc_classic.make.txt: Updated. 2006-05-03 David Turner <david@freetype.org> Allow compilation again with C++ compilers. * include/freetype/internal/ftmemory.h (FT_ASSIGNP, FT_ASSIGNP_INNER): New macros which do the actual assignment, and which exist in two variants (for C and C++). Update callers accordingly. 2006-05-03 Werner Lemberg <wl@gnu.org> * include/freetype/config/ftoption.h (FT_STRICT_ALIASING): Removed. 2006-05-02 Werner Lemberg <wl@gnu.org> * include/freetype/internal/ftmemory.h: s/new/newsz/ (for C++). (FT_ALLOC): Remove redundant redefinition. * builds/compiler/gcc-dev.mk (CFLAGS) [g++]: Don't use `-Wstrict-prototypes'. * src/base/ftstream.c (FT_Stream_EnterFrame): Add cast. * include/freetype/config/ftconfig.h (FT_BASE_DEF) [__cplusplus]: Remove `extern'. 2006-05-02 David Turner <david@freetype.org> Update the memory management functions and macros to safely deal with array size buffer overflows. This corresponds to attempts to allocate arrays that are too large. For an example, consider the following code: count = read_uint32_from_file(); array = malloc( sizeof ( Item ) * count ); for ( nn = 0; nn < count; nn++ ) array[nn] = read_item_from_file(); If `count' is larger than `FT_UINT_MAX/sizeof(Item)', the multiplication overflows, and the array allocated os smaller than the data read from the file. In this case, the heap will be trashed, and this can be used as a denial-of-service attack, or make the engine crash later. The FT_ARRAY_NEW and FT_ARRAY_RENEW macros now ensure that the new count is no larger than `FT_INT_MAX/item_size', otherwise a new error code `FT_Err_Array_Too_Large' will be returned. Note that the memory debugger now works again when FT_DEBUG_MEMORY is defined. FT_STRICT_ALIASING has disappeared; the corresponding code is now the default. * include/freetype/config/ftconfig.h (FT_BASE_DEF) [!__cplusplus]: Don't use `extern'. * include/freetype/fterrdef.h (FT_Err_Array_Too_Large): New error code. * include/freetype/internal/ftmemory.h (FT_DEBUG_INNER) [FT_DEBUG_MEMORY]: New macro. (ft_mem_realloc, ft_mem_qrealloc): Pass new object size count also. (ft_mem_alloc_debug, ft_mem_qalloc_debug, ft_mem_realloc_debug, ft_mem_qrealloc_debug, ft_mem_free_debug): Removed. (FT_MEM_ALLOC, FT_MEM_REALLOC, FT_MEM_QALLOC, FT_MEM_QREALLOC, FT_MEM_FREE): Redefine. (FT_MEM_NEW_ARRAY, FT_MEM_RENEW_ARRAY, FT_MEM_QNEW_ARRAY, FT_MEM_QRENEW_ARRAY): Redefine. (FT_ALLOC_MULT, FT_REALLOC_MULT, FT_MEM_QALLOC_MULT, FT_MEM_QREALLOC_MULT): New macros. Update callers where appropriate. (FT_MEM_SET_ERROR): Slightly redefine. * src/base/ftdbgmem.c (_ft_debug_file, _ft_debug_lineno) [FT_DEBUG_MEMORY]: New global variables, replacing... (FT_MemTableRec) [FT_DEBUG_MEMORY]: Remove `filename' and `line_no'. Update all callers. (ft_mem_debug_alloc) [FT_DEBUG_MEMORY]: Avoid possible integer overflow. (ft_mem_alloc_debug, ft_mem_realloc_debug, ft_mem_qalloc_debug, ft_mem_qrealloc_debug, ft_mem_free_debug): Removed. * src/base/ftmac.c (read_lwfn): Catch integer overflow. * src/base/ftrfork.c (raccess_guess_darwin_hfsplus): Ditto. * src/base/ftutil.c: Remove special code for FT_STRICT_ALIASING. (ft_mem_alloc, ft_mem_realloc, ft_mem_qrealloc): Rewrite. * include/freetype/ftstream.h (FT_FRAME_ENTER, FT_FRAME_EXIT, FT_FRAME_EXTRACT, FT_FRAME_RELEASE): Use FT_DEBUG_INNER to report the place where the frames were entered, extracted, exited or released in the memory debugger. * src/base/ftstream.c (FT_Stream_ReleaseFrame) [FT_DEBUG_MEMORY]: Call ft_mem_free. (FT_Stream_EnterFrame) [FT_DEBUG_MEMORY]: Use ft_mem_qalloc. (FT_Stream_ExitFrame) [FT_DEBUG_MEMORY]: Use ft_mem_free. 2006-04-30 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * src/base/ftobjs.c (Mac_Read_POST_Resource): Correct pfb_pos initialization, remove extra cast to copy to pfb_lenpos. This fixes parsing of PFB fonts with MacOS resource fork (bug introduced 2003-09-11). Patch provided by Huib-Jan Imbens <ft@imbens.nl>. 2006-04-29 Werner Lemberg <wl@gnu.org> Further C library abstraction. Based on a patch from msn2@bidyut.com. * include/freetype/config/ftstdlib.h (FT_CHAR_BIT, FT_FILE, ft_fopen, ft_fclose, ft_fseek, ft_ftell, ft_fread, ft_smalloc, ft_scalloc, ft_srealloc, ft_sfree, ft_labs): New wrapper macros for C library functions. Update all users accordingly (and catch some other places where the C library function was used instead of the wrapper functions). * src/base/ftsystem.c: Don't include stdio.h and stdlib.h. * src/gzip/zutil.h [MSDOS && !(__TURBOC__ || __BORLANDC__)]: Don't include malloc.h. * builds/unix/unix-def.in (datarootdir): Define, for autoconf 2.59c and forthcoming versions. 2006-04-28 Werner Lemberg <wl@gnu.org> * src/lzw/ftlzw.c, src/lzw/zopen.c, src/lzw/zopen.h: Removed, obsolete. 2006-04-27 yi luo <luoyi.ly@gmail.com> * builds/win32/visualc/freetype.vcproj: Updated. 2006-04-26 David Turner <david@freetype.org> * Version 2.2 released. ======================= Tag sources with `VER-2-2-0'. 2006-04-26 Werner Lemberg <wl@gnu.org> * src/psaux/psobjs.c (shift_elements): Don't use FT_Long but FT_PtrDist for `delta'. Reported by Céline PILLET <Celine.Pillet@Tagginfo.com>. 2006-04-21 David Turner <david@freetype.org> * include/freetype/ftincrem.h: Documentation updates. (FT_Incremental_Interface): New typedef. * include/freetype/ftmodapi.h, include/freetype/ftglyph.h: Documentation updates. * include/freetype/freetype.h: Documentation update.

Update declarations according to the changes in the corresponding source files. Note that these files are not used by FreeType clients; all public APIs of the cache module have been already moved to `include/freetype/ftcache.h', and all FT_CACHE_INTERNAL_XXXX_H macros resolve to it. Reason for the move is to allow modifications of the internals without interferences with rogue clients. Note that there are no known clients that access the cache internals at the moment. * builds/unix/install.mk (install): Don't install headers from $(CACHE_H). Remove `freetype/cache' from the target directory. * include/freetype/config/ftheader.h (FT_CACHE_MANAGER_H, FT_CACHE_INTERNAL_MRU_H, FT_CACHE_INTERNAL_MANAGER_H, FT_CACHE_INTERNAL_CACHE_H, FT_CACHE_INTERNAL_GLYPH_H, FT_CACHE_INTERNAL_IMAGE_H, FT_CACHE_INTERNAL_SBITS_H): Point to FT_CACHE_H. * src/cache/ftcbasic.c, src/cache/ftccache.h, src/cache/ftccback.h, src/cache/ftccmap.c, src/cache/ftcglyph.c, src/cache/ftcglyph.h, src/cache/ftcimage.c, src/cache/ftcimage.h, src/cache/ftcmanag.c, src/cache/ftcmanag.h, src/cache/ftcmru.h, src/cache/ftcsbits.c, src/cache/ftcsbits.h: Don't use the FT_CACHE_INTERNAL_XXX_H macros but include the headers directly (which are now in `src/cache'). * src/cache/ftccache.c: Don't use the FT_CACHE_INTERNAL_XXX_H macros but include the headers directly. (FTC_Cache_Init, FTC_Cache_Done, FTC_Cache_NewNode, FTC_Cache_Lookup, FTC_Cache_RemoveFaceID): Declare as FT_LOCAL_DEF. * src/cache/ftccache.c: Don't use the FT_CACHE_INTERNAL_XXX_H macros but include the headers directly.

(FTC_MruList_Find, FTC_MruList_Lookup) [!FTC_INLINE]: Compile conditionally. Declare as FT_LOCAL_DEF. * builds/win32/visualc/freetype.dsp: Update project file, add missing base source files (ftstroke.c, ftxf86.c, etc.). * src/autofit/afcjk.c, src/autofit/aflatin.c, src/base/ftobjs.c, src/cff/cffobjs.c, src/cid/cidobjs.c, src/pfr/pfrobjs.c, src/sfnt/sfobjs.c, src/sfnt/ttmtx.c, src/type1/t1afm.c, src/type1/t1objs.c: Remove compiler warnings when building with Visual C++ 6 and /W4. * src/autofit/aflatin.c (af_latin_hints_init): Disable horizontal hinting for italic/oblique fonts. * src/truetype/ttpload.c, src/truetype/ttpload.h (tt_face_get_device_metrics): Change second argument to `FT_UInt'. 2006-03-06 David Turner <david@freetype.org> * src/cache/ftcmanag.c (FTC_Manager_Lookup_Size): Prevent crashes in Mozilla/FireFox print preview in Ubuntu Hoary. 2006-02-28 Chia-I Wu <b90201047@ntu.edu.tw> * src/base/ftutil.c (ft_mem_qalloc) [FT_STRICT_ALIASING]: Do not return error when size == 0. 2006-02-28 Chia-I Wu <b90201047@ntu.edu.tw> * src/base/ftobjs.c (FT_Done_Library): Remove modules in reverse order so that type42 module is removed before truetype module. This avoids double free in some occasions. 2006-02-28 David Turner <david@freetype.org> * Release candidate VER-2-2-0-RC4. ---------------------------------- * docs/CHANGES: Documentation updates. 2006-02-28 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * modules.cfg (BASE_EXTENSIONS): Compile in ftgxval.c by default to build ftvalid in ft2demos. It works as dummy ABI if gxvalid is not built. 2006-02-27 Werner Lemberg <wl@gnu.org> * include/freetype/cache/ftccache.h [FT_CONFIG_OPTION_OLD_INTERNALS]: Remove declaration of ftc_node_done. * src/cache/ftccache.c (ftc_node_destroy) [!FT_CONFIG_OPTION_OLD_INTERNALS]: Mark as FT_LOCAL_DEF.

(cff_index_access_element): Ignore invalid entries in index files. 2006-02-27 Chia-I Wu <b90201047@ntu.edu.tw> * src/base/ftobjs.c (FT_Set_Char_Size): Check the case where width or height is 0. 2006-02-27 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * builds/mac/FreeType.m68k_cfm.make.txt, builds/mac/FreeType.m68k_far.make.txt, builds/mac/FreeType.ppc_carbon.make.txt, builds/mac/FreeType.ppc_classic.make.txt: Update to new header inclusion introduced on 2006-02-16. 2006-02-27 Chia-I Wu <b90201047@ntu.edu.tw> * src/base/ftobjs.c (GRID_FIT_METRICS): New macro. (ft_glyphslot_grid_fit_metrics, FT_Load_Glyph) [GRID_FIT_METRICS]: Re-enable glyph metrics grid-fitting. It is now done in the base layer. (FT_Set_Char_Size, FT_Set_Pixel_Sizes): Make sure the width and height are not too small or too large, just like we were doing in 2.1.10. * src/autofit/afloader.c (af_loader_load_g): The vertical metrics are not scaled. 2006-02-26 Werner Lemberg <wl@gnu.org> * docs/release: Minor additions and clarifications. * docs/CHANGES: Updated to reflect many fixes for backward compatibility. Still incomplete. 2006-02-26 David Turner <david@freetype.org> * src/base/ftobjs.c (ft_recompute_scaled_metrics): Re-enable conservative rounding of metrics to avoid breaking clients like Pango (see https://bugzilla.gnome.org/show_bug.cgi?id=327852). 2006-02-25 Werner Lemberg <wl@gnu.org> * devel/ftoption.h: Synchronize with include/freetype/config/ftoption.h. * src/cache/ftccache.c (ftc_node_destroy): Use FT_LOCAL_DEF (again). 2006-02-25 David Turner <david@freetype.org> Fix compiler warnings as well as C++ compilation problems. Add missing prototypes. * src/autofit/afcjk.c, src/base/ftobjs.c, src/base/ftutil.c, src/bdf/bdfdrivr.c, src/cff/cffcmap.c, src/cff/cffobjs.c, src/psaux/afmparse.c,, src/psaux/t1cmap.c, src/smooth/ftgrays.c src/tools/apinames.c, src/truetype/ttdriver.c: Add various casts, initialize variables, and decorate functions with FT_CALLBACK_DEF, etc., to fix compiler warnings (and C++ compiling errors). * src/cache/ftcbasic.c: Fix `-Wmissing-prototypes' warnings with gcc. * builds/unix/ftsystem.c: Don't include FT_INTERNAL_OBJECTS_H but FT_INTERNAL_STREAM_H. * src/base/ftsystem.c: Include FT_INTERNAL_STREAM_H. * include/freetype/config/ftheader.h (FT_PFR_H): New macro. * include/freetype/config/ftoption.h (FT_STRICT_ALIASING): Don't define for C++. * include/freetype/internal/services/svotval.h: Don't include FT_OPENTYPE_VALIDATE_H but FT_INTERNAL_VALIDATE_H. * include/freetype/internal/services/svpfr.h: Include FT_PFR_H. * src/gzip/ftgzip.c: Include FT_GZIP_H. * src/lzw/ftlzw.c, src/lzw/ftlzw2.c: Include FT_LZW_H. * src/sfnt/ttbdf.c (tt_face_load_bdf_props): Rearrange code. 2006-02-24 Chia-I Wu <b90201047@ntu.edu.tw> * src/base/ftoutln.c (FT_OUTLINE_GET_CONTOUR, ft_contour_has, ft_contour_enclosed, ft_outline_get_orientation): Commented out. We have to wait until `FT_GlyphSlot_Own_Bitmap' is stabilized. (FT_Outline_Embolden): Use `FT_Outline_Get_Orientation'. 2006-02-24 Chia-I Wu <b90201047@ntu.edu.tw> * include/freetype/ftbitmap.h (FT_Bitmap_Embolden): Update documentation. * include/freetype/ftsynth.h (FT_GlyphSlot_Own_Bitmap), src/base/ftsynth.c (FT_GlyphSlot_Own_Bitmap): New function to make sure a glyph slot owns its bitmap. It is also marked experimental and due to change. (FT_GlyphSlot_Embolden): Undo the last change. It turns out that rendering the outline confuses some applications. 2006-02-24 David Turner <david@freetype.org> * Release candidate VER-2-2-0-RC3. ---------------------------------- * src/cache/ftcbasic.c: Correct compatibility hack bug. 2006-02-24 Chia-I Wu <b90201047@ntu.edu.tw> * include/freetype/freetype.h (FT_Size_RequestRec): Change the type of `width' and `height' to `FT_Long'. (enum FT_Size_Request_Type), src/base/ftobjs.c (FT_Request_Metrics): New request type `FT_SIZE_REQUEST_TYPE_SCALES' to specify the scales directly. 2006-02-23 David Turner <david@freetype.org> Two BDF patches from Debian libfreetype6 for 2.1.10. * src/bdf/bdflib.c (_bdf_parse_glyphs): Fix a bug with zero-width glyphs. Fix a problem with large encodings. Fix binary compatibility issues for gnustep-back (GNUstep backend module) which still crashes under Sarge. * src/cache/ftccmap.c (FTC_OldCMapType, FTC_OldCMapIdRec, FTC_OldCMapDesc) [FT_CONFIG_OPTION_OLD_INTERNALS]: New data structures and enumerations. (FTC_CMapCache_Lookup) [FT_CONFIG_OPTION_OLD_INTERNALS]: New compatibility code. * src/cache/ftcbasic.c: Fix a silly bug that prevented our `hack' to support rogue clients compiled against 2.1.7 to work correctly. This probably explains the GNUstep crashes with the second release candidate. 2006-02-23 Chia-I Wu <b90201047@ntu.edu.tw> * include/freetype/ftoutln.h (enum FT_Orientation): New value `FT_ORIENTATION_NONE'. * src/base/ftoutln.c (FT_OUTLINE_GET_CONTOUR, ft_contour_has, ft_contour_enclosed, ft_outline_get_orientation): Another version of `FT_Outline_Get_Orientation'. This version differs from the public one in that each part (contour not enclosed in another contour) of the outline is checked for orientation. (FT_Outline_Embolden): Use `ft_outline_get_orientation'. * src/base/ftsynth.c (FT_GlyphSlot_Embolden): Render the outline and use bitmap's embolden routine when the outline one failed. 2006-02-22 Chia-I Wu <b90201047@ntu.edu.tw> * modules.cfg: Compile in ftotval.c and ftxf86.c by default for ABI compatibility. * src/sfnt/sfobjs.c (sfnt_done_face): Fix a memory leak. * src/sfnt/ttsbit0.c (tt_sbit_decoder_load_bit_aligned, tt_sbit_decoder_load_byte_aligned) [FT_OPTIMIZE_MEMORY]: Fix sbit loading. (Only tested with bit aligned sbit with x_pos == 0.) * src/truetype/ttpload.c (tt_face_load_hdmx, tt_face_get_device_metrics) [FT_OPTIMIZE_MEMORY]: `hdmx' is not actually used. 2006-02-21 David Turner <david@freetype.org> Add a new API named FT_Get_TrueType_Engine_Type to determine whether we have a patented, unpatented, or unimplemented TrueType bytecode interpreter. The FT_Get_Module_Flags API was removed consequently. * include/freetype/ftmodapi.h (FT_Module_Get_Flags): Removed. Replaced with... (FT_Get_TrueType_Engine_Type): This. (FT_TrueTypeEngineType): New enumeration. * include/freetype/internal/ftserv.h (FT_SERVICE_TRUETYPE_ENGINE_H): New macro. * src/base/ftobjs.c: Include FT_SERVICE_TRUETYPE_ENGINE_H. (FT_Module_Get_Flags): Removed. Replaced with... (FT_Get_TrueType_Engine_Type): This. * src/truetype/ttdriver.c: Include FT_SERVICE_TRUETYPE_ENGINE_H. (tt_service_truetype_engine): New service structure. (tt_services): Register it. * include/freetype/internal/services/svtteng.h: New file. * src/sfnt/sfobjs.c (sfnt_load_face): Fix silly bug that prevented embedded bitmaps from being correctly listed and used. * src/sfnt/ttmtx.c (tt_face_load_hmtx): Disable memory optimization if FT_CONFIG_OPTION_OLD_INTERNALS is used. The is necessary because libXfont is directly accessing the HMTX data, unfortunately. Fix some compiler warnings. (tt_face_get_metrics): Ditto. * src/pfr/pfrsbit.c (pfr_slot_load_bitmap): Fix handling of character advances. 2006-02-20 David Turner <david@freetype.org> Support binary compatibility with the X.Org server's Xfont library. Note that this change unfortunately prevents memory optimizations for the embedded bitmap loader. * include/freetype/internal/sfnt.h (SFNT_Interface): Move `set_sbit_strike' and `load_sbit_metrics' fields to the location of version 2.1.8. * src/sfnt/sfdriver.c (tt_face_set_sbit_strike_stub): Call FT_Size_Request. (sfnt_interface): Updated. * src/sfnt/ttsbit.c [FT_CONFIG_OPTION_OLD_INTERNALS]: Don't load ttsbit0.c. (tt_load_sbit_metrics): Make `sbit_small_metrics_fields' static. * src/sfnt/ttsbit.h: Updated. 2006-02-17 David Turner <david@freetype.org> * builds/unix/unix-cc.in (LINK_LIBRARY): Don't filter out exported functions anymore. This ensures that all FT_BASE internal functions are available for dynamic linking. * include/freetype/ftcache.h (FTC_IMAGE_TYPE_COMPARE, FTC_IMAGE_TYPE_HASH), src/cache/ftcbasic.c (FTC_OldFontRec, FTC_OldImageDescRec, FTC_ImageCache_Lookup, FTC_Image_Cache_New, FTC_OldImageDesc, FTC_OLD_IMAGE_FORMAT, ftc_old_image_xxx, ftc_image_type_from_old_desc, FTC_Image_Cache_Lookup, FTC_SBitCache_Lookup, FTC_SBit_Cache_New, FTC_SBit_Cache_Lookup) [FT_CONFIG_OPTION_OLD_INTERNALS]: Try to revive old functions of the cache sub-system. We try to recognize old legacy signatures with a gross hack (hope it works). 2006-02-17 Werner Lemberg <wl@gnu.org> * devel/ftoption.h: Synchronize with include/freetype/config/ftoption.h. 2006-02-16 David Turner <david@freetype.org> Massive changes to the internals to respect the internal object layouts and exported functions of FreeType 2.1.7. Note that the cache sub-system cannot be fully retrofitted, unfortunately. * include/freetype/config/ftoption.h (FT_CONFIG_OPTION_OLD_INTERNALS): New macro. * include/freetype/ftcache.h, include/freetype/cache/ftccache.h, include/freetype/cache/ftccmap.h, include/freetype/internal/ftcalc.h, include/freetype/internal/ftdriver.h, include/freetype/internal/ftmemory.h, include/freetype/internal/ftobjs.h, include/freetype/internal/psaux.h, include/freetype/internal/sfnt.h, include/freetype/internal/t1types.h, include/freetype/internal/tttypes.h, src/base/ftcalc.c, src/base/ftdbgmem.c, src/base/ftobjs.c, src/base/ftutil.c, src/bdf/bdfdrivr.c, src/cache/ftccache.c, src/cache/ftccback.h, src/cache/ftcmanag.c, src/cff/cffdrivr.c, src/cid/cidriver.c, src/pcf/pcfdrivr.c, src/pfr/pfrdrivr.c, src/psaux/psauxmod.c, src/sfnt/sfdriver.c, src/truetype/ttdriver.c, src/type1/t1driver.c, src/type1/t1objs.c, src/type42/t42drivr.c, src/winfonts/winfnt.c: Use FT_CONFIG_OPTION_OLD_INTERNALS to revive old functions and data structures. Move newly added structure elements to the end of the affected structure and add stub fields (if FT_CONFIG_OPTION_OLD_INTERNALS is defined) to assure binary compatibility with older FreeType versions. Use FT_CONFIG_OPTION_OLD_INTERNALS to add function stubs for old functions: ft_stub_set_char_sizes ft_stub_set_pixel_sizes Rename the following internal functions to provide the old function names as stubs: FT_Alloc -> ft_mem_alloc FT_QAlloc -> ft_mem_qalloc FT_Realloc -> ft_mem_realloc FT_QRealloc -> ft_mem_qrealloc FT_Free -> ft_mem_free FT_Alloc_Debug -> ft_mem_alloc_debug FT_QAlloc_Debug -> ft_mem_qalloc_debug FT_Realloc_Debug -> ft_mem_realloc_debug FT_QRealloc_Debug -> ft_mem_qrealloc_debug FT_Free_Debug -> ft_mem_free_debug 2006-02-15 Chia-I Wu <b90201047@ntu.edu.tw> * include/freetype/internal/ftobjs.h (FT_Face_InternalRec): Remove unused `max_points' and `max_contours'. * src/cid/cidobjs.c (cid_face_init), src/type1/t1objs.c (T1_Face_Init), src/type42/t42objs.c (T42_Face_Init): Update. * include/freetype/internal/tttypes.h (TT_FaceRec): Remove unused `max_components'. * src/truetype/ttinterp.h (TT_ExecContextRec): Remove unused `loadSize' and `loadStack'. * src/truetype/ttinterp.c (TT_Done_Context, TT_Load_Context), src/sfnt/ttload.c (tt_face_load_maxp): Update. * src/cff/cffobjs.h (cff_size_select), src/sfnt/sfdriver.c (sfnt_interface), src/truetype/ttdriver.c (tt_size_request): Fix compiler errors/warnings when TT_CONFIG_OPTION_EMBEDDED_BITMAPS is not defined. * src/sfnt/ttmtx.c (tt_face_load_hmtx, tt_face_get_metrics): Fix possible segment faults for the non-FT_OPTIMIZE_MEMORY'ed versions. (finally!) For most OpenType tables, `tt_face_load_xxxx' simply loads the table and `face->root' is set later in `sfnt_load_face'. Here, we try to make this work for _all_ tables. Also improve tracing messages. * src/sfnt/ttsbit.c, src/sfnt/ttsbit0.c, src/sfnt/ttload.c, src/sfnt/ttmtx.c: all `tt_face_load_xxxx' should load the table and then exit. Error handling or setting face->root is done later in `sfnt_load_face'. * src/sfnt/sfobjs.c (sfnt_load_face): Work harder. Mac bitmap-only fonts are not scalable. Check that `face->header.Units_Per_EM' is not zero. (LOAD_, LOADM_): Emit pretty trace messages. * src/sfnt/ttsbit0.c (tt_face_load_strike_metrics): Read metrics from `eblc'. * src/sfnt/ttcmap.c (tt_face_build_cmaps), src/sfnt/ttpost.c (load_format_20, load_format_25, tt_face_get_ps_name): Use face->max_profile.numGlyphs, instead of face->root.num_glyphs. 2006-02-14 Werner Lemberg <wl@gnu.org> * include/freetype/ftoutln.h (FT_Outline_Embolden): Mention in documentation that negative strength values are possible. Give an example call. * include/freetype/freetype.h (FT_GlyphSlotRec): Improve documentation of `outline' field. * src/sfnt/sfobjs.c: Include FT_INTERNAL_DEBUG_H. * src/sfnt/sfdriver.c: Include ttmtx.h. * src/autofit/afcjk.c: Include aftypes.h and aflatin.h. 2006-02-14 Chia-I Wu <b90201047@ntu.edu.tw> * src/sfnt/ttmtx.c (tt_face_get_metrics): Typo. 2006-02-14 Chia-I Wu <b90201047@ntu.edu.tw> * src/sfnt/ttmtx.c (tt_face_load_hhea, tt_face_load_hmtx): Simply return error if table is missing. Check table length in non-FT_OPTIMIZE_MEMORY'ed `tt_face_load_hmtx'. * src/sfnt/sfobjs.c (sfnt_load_face): Take care of missing metrics tables. The last change makes Mac bitmap-only font not load and this fixes it. * src/truetype/ttgload.c (load_truetype_glyph): Fix compilation error when FT_CONFIG_OPTION_INCREMENTAL is defined. 2006-02-13 Chia-I Wu <b90201047@ntu.edu.tw> Clean up the SFNT_Interface. In this final pass, `load_hmtx' is split from `load_hhea'. * include/freetype/internal/sfnt.h, src/sfnt/sfdriver.c, src/sfnt/ttmtx.c, src/sfnt/ttmtx.h: Split `hmtx' from `hhea'. * src/sfnt/sfobjs.c (sfnt_load_face): Update. 2006-02-13 Chia-I Wu <b90201047@ntu.edu.tw> * src/sfnt/ttmtx.h, src/sfnt/ttmtx.c: Why are there two copies of code... 2006-02-13 Chia-I Wu <b90201047@ntu.edu.tw> Clean up the SFNT_Interface. In this pass, we want to treat the font directory (offset table and table directory) as a normal table like the others. This also means that TTCs are no longer recognized there but in `init_face'. * include/freetype/internal/sfnt.h (SFNT_Interface), src/sfnt/sfdriver.c: `load_sfnt_header' and `load_directory' are combined and renamed to `load_font_dir'. * src/sfnt/ttload.h, src/sfnt/ttload.c: s/sfnt_dir_check/check_table_dir/. `sfnt_init' is moved to sfobjs.c and renamed to `sfnt_open_font'. `tt_face_load_sfnt_header' and `tt_face_load_directory' are combined and renamed to `tt_face_load_font_dir'. * src/sfnt/sfobjs.c (sfnt_init_face): Recognize TTC here. 2006-02-13 Chia-I Wu <b90201047@ntu.edu.tw> Clean up the SFNT_Interface. Table loading functions are now named after the tables' tags; `hdmx' is TrueType-specific and thus the code is moved to the truetype module; `get_metrics' is moved here from the truetype module so that the code can be shared with the cff module. This pass involves no real changes. That is, the code is moved verbatim mostly. The only exception is the return value of `tt_face_get_metrics'. * include/freetype/internal/sfnt.h, src/sfnt/rules.mk, src/sfnt/sfdriver.c, src/sfnt/sfnt.c, src/sfnt/sfobjs.c, src/sfnt/ttload.c, src/sfnt/ttload.h, src/sfnt/ttsbit.c, src/sfnt/ttsbit.h, src/sfnt/ttsbit0.c: Clean up the SFNT_Interface. * src/sfnt/ttmtx.c, src/sfnt/ttmtx.h: New files. Metrics-related tables' loading and parsing code is moved to here. Move `tt_face_get_metrics' here from the truetype module. The return value is changed from `void' to `FT_Error'. * include/freetype/internal/fttrace.h: New trace: ttmtx. * src/truetype/ttpload.c, src/truetype/ttpload.h: `hdmx' loading and parsing code is moved here. New function `tt_face_load_prep' split from `tt_face_load_fpgm'. `tt_face_load_fpgm' returns `FT_Err_Ok' if `fpgm' doesn't exist. * src/cff/cffgload.c, src/cff/cffobjs.c: Update. * src/truetype/ttgload.c, src/truetype/ttobjs.c: Update. 2006-02-11 Chia-I Wu <b90201047@ntu.edu.tw> * src/autofit/afcjk.c (af_cjk_metrics_init): Fix a stupid bug... * src/autofit/aflatin.c (af_latin_metrics_init_widths): Use AF_LatinMetricsRec as the dummy metrics because we cast the metrics to it later in `af_latin_hints_link_segments'. 2006-02-11 Chia-I Wu <b90201047@ntu.edu.tw> * include/freetype/config/ftoption.h (AF_CONFIG_OPTION_CJK): #define to enable autofit CJK script support. (#define'd by default.) * src/autofit/aflatin.h (AF_LATIN_CONSTANT): New macro. * src/autofit/aflatin.c (af_latin_metrics_init_widths): Make sure that `edge_distance_threshold' is always set. (af_latin_hints_link_segments): Potential divide-by-zero bug. Use latin constant in the scoring formula. * src/autofit/afcjk.c: Minor updates due to the above three changes. * docs/TODO, docs/CHANGES: Updated. 2006-02-09 Chia-I Wu <b90201047@ntu.edu.tw> Introduce experimental autofit CJK module based on akito's autohint patch. You need to #define AF_MOD_CJK in afcjk.c to enable it. * src/autofit/afglobal.c, src/autofit/afcjk.h, src/autofit/afcjk.c, src/autofit/rules.mk, src/autofit/autofit.c, src/autofit/aftypes.h: Add CJK module based on akito's autohint patch. * src/autofit/afhints.h (AF_SegmentRec): New field `len' for the overlap length of the segments. (AF_SEGMENT_LEN, AF_SEGMENT_DIST): New macros. * src/autofit/aflatin.h (af_latin_metrics_init_widths), src/autofit/aflatin.c (af_latin_metrics_init_widths): Made `FT_LOCAL'. Use the character given by the caller. (af_latin_metrics_init_widths, af_latin_hints_link_segments): Scale the thresholds. * src/autofit/afloader.c (af_loader_load_g): Respect AF_SCALER_FLAG_NO_ADVANCE. 2006-02-09 Werner Lemberg <wl@gnu.org> * src/cid/cidparse.c (cid_parse_new): Remove shadowing variable. 2006-02-09 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * src/cid/cidparse.c (cid_parse_new): Fix for abnormally short or broken CIDFont. Reported by Taek Kwan(TK) Lee (see ft-devel 2005-11-02). 2006-02-08 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * builds/unix/configure.ac: Fix bug for `--with-old-mac-fonts' option on UNIX platform. It has been broken since 2006-01-11. 2006-02-01 Werner Lemberg <wl@gnu.org> * src/otvalid/module.mk: s/otvalid_module_class/otv_module_class/. * src/gxvalid/module.mk: s/gxvalid_module_class/gxv_module_class/. * builds/unix/unixddef.mk: Actually do define PLATFORM (fixing change from 2006-01-31). (TOP_DIR, OBJ_DIR): Update. * builds/unix/install.mk (install): Fix path for ftmodule.h. * Makefile, *.mk, builds/unix/unix-cc.in, builds/unix-def.in: Use `?=' where appropriate. * builds/detect.mk (TOP_DIR), builds/os2/os2-dev.mk (TOP_DIR), builds/win32/w32-dev.mk (TOP_DIR): Removed. Defined elsewhere. 2006-01-31 Werner Lemberg <wl@gnu.org> Implement new, simplified module selection. With GNU make it is now sufficient to modify a single file, `modules.cfg', to control the inclusion of modules and base extension files. This change also fixes the creation of ftmodule.h; it now depends on `modules.cfg' and thus is rebuilt only if necessary. Finally, a version of `ftoption.h' in OBJ_DIR is preferred over the default location. * modules.cfg: New file. * builds/freetype.mk: Don't include `modules.mk'. Include all `rules.mk' files as specified in `modules.cfg'. (FTOPTION_FLAG, FTOPTION_H): New variables. (FT_CFLAGS): Add macro definition for FT_CONFIG_MODULES_H. Add FTOPTION_FLAG. ($(FT_INIT_OBJ)): Don't use FT_MODULE_LIST. (CONFIG_H): Add FTMODULE_H and FTOPTION_H. (INCLUDES): Add DEVEL_DIR. (INCLUDE_FLAGS, FTSYS_SRC, FTSYS_OBJ, FTDEBUG_SRC, FTDEBUG_OBJ, OBJ_M, OBJ_S): Use `:=', not `='. (remove_ftmodule_h): New phony target to delete `ftmodule.h'. (distclean): Add remove_ftmodule_h. * builds/modules.mk: (MODULE_LIST): Removed. (make_module_list, clean_module_list): Replace targets with... (FTMODULE_H_INIT, FTMODULE_H_CREATE, FTMODULE_H_DONE): New variables. Reason for the change is that it is not possible to have a phony prerequisite which is run only if the target file must be rebuilt (phony prerequisites act like subroutines and are *always* executed). We only want to rebuild `ftmodule.h' if `module.cfg' is changed. Update all callers. ($FTMODULE_H)): Rule to create `ftmodule.h', depending on `modules.cfg'. * builds/toplevel.mk: Rewrite and simplify module handling. (MODULES_CFG, FTMODULE_H): New variables. Include MODULES_CFG. (MODULES): New variable to include all `module.mk' and `rules.mk' files. We no longer use make's `wildcard' function for this. * Makefile (USE_MODULES): Remove. Update all users. (OBJ_DIR): Define it here. * src/*/module.mk: Change make_module_list: foo foo: ... to FTMODULE_H_COMMANDS += FOO define FOO ... endef in all files. `FTMODULE_H_COMMANDS' is used in `FTMODULE_H_CREATE'. * src/base/rules.mk (BASE_EXT_SRC): Use BASE_EXTENSIONS. * builds/unix/detect.mk (setup): Always execute `configure' script. (have_mk): Rename to... (have_Makefile): This. Don't use `strip' function. * builds/unix/unix.mk: Include `install.mk' only if BUILD_PROJECT is defined. (have_mk): Don't use `strip' function. Test for unix-def.mk in OBJ_DIR, not BUILD_DIR (and invert the test accordingly). * builds/unix/install.mk (install, uninstall): Handle `ftmodule.h'. * builds/os2/os2-dev.mk, builds/unix/unix-dev.mk, builds/win32/w32-bccd.mk, builds/win32/w32-dev.mk: Don't define BUILD_DIR but DEVEL_DIR for development header files. * builds/ansi/ansi-def.mk (TOP_DIR, OBJ_DIR), builds/beos/beos-def.mk (TOP_DIR, OBJ_DIR), builds/unix/unix-def.in (TOP_DIR, OBJ_DIR): Removed. Defined elsewhere. * builds/dos/dos-def.mk (OBJ_DIR), builds/os2/os2-def.mk (OBJ_DIR), builds/win32/win32-def.mk (OBJ_DIR): Removed. Defined elsewhere. * builds/unix/unixddef.mk: Don't define BUILD_DIR but DEVEL_DIR for development header files. Don't define PLATFORM. * configure: Copy `modules.cfg' to builddir if builddir != srcdir. Update snippet taken from autoconf's m4sh.m4 to current CVS version.

(TT_CMAP_FLAG_UNSORTED, TT_CMAP_FLAG_OVERLAPPED): New macros. * src/sfnt/ttcmap.c (OPT_CMAP4): Removed as it is always defined. (TT_CMap4Rec_): Remove `old_charcode' and `table_length'. (tt_cmap4_reset): Removed. (tt_cmap4_init): Updated accordingly. (tt_cmap4_next): Updated accordingly. Take care of overlapping segments. (tt_cmap4_validate): Make sure the subtable is large enough. Do not check glyph_ids because some fonts set the length wrongly. Also, if all segments have offset 0, glyph_ids is always invalid. It does not cause any problem so far only because the check misses equality. Distinguish between unsorted and overlapping segments. (tt_cmap4_char_map_linear, tt_cmap4_char_map_binary): New functions to do `charcode => glyph index' by linear/binary search. (tt_cmap4_char_index, tt_cmap4_char_next): Use tt_cmap4_char_map_linear and tt_cmap4_char_map_binary. (tt_face_build_cmaps): Treat the return value of validator as flags for cmap. 2005-11-29 Chia-I Wu <b90201047@ntu.edu.tw> * src/sfnt/ttcmap.c (TT_CMap12Rec_, tt_cmap12_init, tt_cmap12_next): New structures and functions for fast `next char'. (tt_cmap12_char_map_binary): New function to do `charcode => glyph index' by binary search. (tt_cmap12_char_index, tt_cmap12_char_next): Use tt_cmap12_char_map_binary. (tt_face_build_cmaps): Check table and offset correctly (equality is missing). 2005-11-15 Detlef Würkner <TetiSoft@apg.lahn.de> * builds/amiga/smakefile: Adjusted the compiler options to the current sources, now really builds the gxvalid, gzip and psnames modules. * builds/amiga/src/base/ftsystem.c: The assumed Seek() position in the file cache was off by one byte which could cause false errors in font files. 2005-11-24 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * builds/mac/FreeType.m68k_far.make.txt, builds/mac/FreeType.m68k_cfm.make.txt, builds/mac/FreeType.ppc_classic.make.txt, builds/mac/FreeType.ppc_carbon.make.txt: Updated for MPW to build all available modules. 2005-11-21 Håvard Wall <haavardw@ifi.uio.no> * src/bdf/bdfdrivr.c (bdf_interpret_style, BDF_Face_Done): Fix small memory leak. 2005-11-21 Werner Lemberg <wl@gnu.org> * src/sfnt/ttload.c (sfnt_init): Add tracing message. 2005-11-21 Chia-I Wu <b90201047@ntu.edu.tw> * src/sfnt/ttsbit0.c (tt_sbit_decoder_load_image): Image_offset was added twice to image_start if image_format was 2 or 5. 2005-11-21 Chia-I Wu <b90201047@ntu.edu.tw> * src/sfnt/sfobjs.c (sfnt_init_face): Check that format_tag is known before loading the table directory. * src/sfnt/ttload.c (tt_face_load_sfnt_header, tt_face_load_directory): Delay sfnt_dir_check from tt_face_load_sfnt_header to tt_face_load_directory. 2005-11-20 Chia-I Wu <b90201047@ntu.edu.tw> * src/sfnt/ttload.c (sfnt_dir_check): Clean up and return correct error code. (sfnt_init): New function to fill in face->ttc_header. A non-TTC font is synthesized into a TTC font with one offset table. (tt_face_load_sfnt_header): Use sfnt_init. Fix an invalid access if the font is TTC and face_index is -1. 2005-11-18 Werner Lemberg <wl@gnu.org> * src/sfnt/ttload.c (tt_face_load_metrics): Ignore excess number of metrics instead of aborting.

A SING Glyphlet Font is an OpenType font that contains the outline(s), either in a `glyf' or `CFF' table, for a glyph; `cmap', `BASE', and `GSUB' tables are present with the same format and functionality as a regular OpenType font; there are no `name', `head', `OS/2', and `post' tables; there are two new tables, `SING' which contains details about the glyphlet, and `META' which contains metadata. Further information on the SING Glyphlet format can be found at: https://www.adobe.com/content/dam/acom/en/devnet/font/pdfs/5148.SING_Tutorial.pdf * include/freetype/tttags.h (TTAG_SING, TTAG_META): New macros for the OpenType tables `SING' and `META'.

2010-02-13 Werner Lemberg <wl@gnu.org> * Version 2.3.12 released. ========================== Tag sources with `VER-2-3-12'. * docs/CHANGES: Updated. * docs/VERSION.DLL: Update documentation and bump version number to 2.3.12. * README, Jamfile (RefDoc), builds/win32/vc2005/freetype.vcproj, builds/win32/vc2005/index.html, builds/win32/vc2008/freetype.vcproj, builds/win32/vc2008/index.html, builds/win32/visualc/freetype.dsp, builds/win32/visualc/freetype.vcproj, builds/win32/visualc/index.html, builds/win32/visualce/freetype.dsp, builds/win32/visualce/freetype.vcproj, builds/win32/visualce/index.html, builds/wince/vc2005-ce/freetype.vcproj, builds/wince/vc2005-ce/index.html, builds/wince/vc2008-ce/freetype.vcproj, builds/wince/vc2008-ce/index.html: s/2.3.11/2.3.12/, s/2311/2312/. * include/freetype/freetype.h (FREETYPE_PATCH): Set to 12. * builds/unix/configure.raw (version_info): Set to 10:0:4. 2010-02-12 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> Improve autotool version checking to work with beta releases. * autogen.sh (check_tool_version): Improve the extraction of version number from "tool --version" output. Some beta releases of autotools have extra strings before version number. 2010-02-12 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> Fix overallocating bug in FT_Outline_New_Internal(). * src/base/ftoutln.c (FT_Outline_New_Internal): The length of FT_Outline->points[] should be numPoints, not 2 * numPoints. Found by Paul Messmer, see https://lists.gnu.org/archive/html/freetype-devel/2010-02/msg00003.html 2010-02-10 Ken Sharp <ken.sharp@artifex.com> Really fix Savannah bug #28678 (part 2). Since we consider `sbw' for the horizontal direction only, we still have to synthesize vertical metrics if the user wants to use the vertical writing direction. * src/cff/cffgload.c (cff_slot_load), src/cid/cidgload.c (cid_slot_load_glyph), src/type1/t1gload.c (T1_Load_Glyph): Synthesize vertical metrics (only) if FT_LOAD_VERTICAL_LAYOUT is set. 2010-02-10 Ken Sharp <ken.sharp@artifex.com> Really fix Savannah bug #28678 (part 1). After long discussion, we now consider the character width vector (wx,wy) returned by the `sbw' Type 1 operator as being part of *one* direction only. For example, if you are using the horizontal writing direction, you get the horizontal and vertical components of the advance width for this direction. Note that OpenType and CFF fonts don't have such a vertical component; instead, the GPOS table can be used to generate two-dimensional advance widths (but this isn't handled by FreeType). * include/freetype/ftincrem.h (FT_Incremental_MetricsRec): Add `advance_v' field to hold the vertical component of the advance value. * src/truetype/ttgload.c (tt_get_metrics), src/cff/cffgload.c (cff_slot_load), src/type1/t1gload.c (T1_Parse_Glyph_And_Get_Char_String), src/cid/cidgload.c (cid_load_glyph): Use it. 2010-02-08 Werner Lemberg <wl@gnu.org> * devel/ftoption.h [FT_CONFIG_OPTION_PIC]: Define. 2010-02-04 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> Prevent NULL pointer dereference passed to FT_Module_Requester. * src/sfnt/sfdriver.c (sfnt_get_interface): Don't use `module'. * src/psnames/psmodule.c (psnames_get_interface): Ditto. * src/cff/cffdrivr.c (cff_get_interface): Check NULL `driver'. * src/truetype/ttdriver.c (tt_get_interface): Ditto. 2010-01-29 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> Fix memory leaks in previous patch. * src/sfnt/sfobjs.c (sfnt_load_face): Don't overwrite the strings allocated for face->root.family_name and style_name. 2010-01-29 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> New parameters for FT_Open_Face() to ignore preferred family names. Preferred family names should be used for legacy systems that can hold only a few faces (<= 4) for a family name. Suggested by Andreas Heinrich. https://lists.gnu.org/archive/html/freetype/2010-01/msg00001.html * include/freetype/ftsnames.h (FT_PARAM_TAG_IGNORE_PREFERRED_FAMILY, FT_PARAM_TAG_IGNORE_PREFERRED_SUBFAMILY): Define. * src/sfnt/sfobjs.c (sfnt_load_face): Check the arguments and ignore preferred family and subfamily names if requested. 2010-01-27 Ken Sharp <ken.sharp@artifex.com> Fix Savannah bug #28678. * src/cff/cffgload.c (cff_slot_load), src/cid/cidgload.c (cid_load_glyph): Handle vertical metrics correctly. * src/type1/t1gload.c (T1_Parse_Glyph_And_Get_Char_String): Handle vertical metrics correctly. (T1_Load_Glyph): Don't synthesize vertical metrics. 2010-01-14 Werner Lemberg <wl@gnu.org> Make FT_Set_Transform work if no renderer is available. * src/base/ftobjs.c (FT_Load_Glyph): Apply `standard' transformation if no renderer is compiled into the library. 2010-01-14 Werner Lemberg <wl@gnu.org> Fix compilation warning. * src/base/ftbase.h: s/LOCAL_DEF/LOCAL/. * src/base/ftobjs.c: Include ftbase.h conditionally. 2010-01-11 Kwang Yul Seo <skyul@company100.net> Provide inline assembly code for RVCT compiler. This is Savannah patch #7059. * include/freetype/config/ftconfig.h (FT_MULFIX_ASSEMBLER, FT_MulFix_arm) [__CC_ARM || __ARM_CC]: Define. 2010-01-08 Ken Sharp <ken.sharp@artifex.com> Fix Savannah bug #28521. Issue #28226 involved a work-around for a font which used the `setcurrentpoint' operator in an invalid way; this operator is only supposed to be used with the result of OtherSubrs, and the font used it directly. The supplied patch removed the block of code which checked this usage entirely. This turns out to be a Bad Thing. If `setcurrentpoint' is being used correctly it should reset the flex flag in the decoder. If we don't do this then the flag never gets reset and we omit any further contours from the glyph (at least until we close the path or similar). * src/psaux/t1decode.c (t1_decoder_parse_charstrings) <op_setcurrentpoint>: Handle `flex_state' correctly. 2010-01-05 Werner Lemberg <wl@gnu.org> Apply reports from clang static analyzer. * src/lzw/ftlzw.c (ft_lzw_file_init), src/base/ftstroke.c (FT_Stroker_ParseOutline), src/base/ftsynth.c (FT_GlyphSlot_Embolden): Remove dead code. * src/base/ftpatent.c (_tt_check_patents_in_table): Initialize `offset_i' and `length_i'. 2010-01-05 Ralph Giles <giles@ghostscript.com> Enable the incremental font interface by default. Ghostscript requires the incremental font interface for handling some Postscript documents. It is moving to using FreeType as its primary renderer; supporting this in the default build makes it Ghostscript to be linked against the system FreeType when one is available. * include/freetype/config/ftoption.h (FT_CONFIG_OPTION_INCREMENTAL): Uncomment. 2010-01-05 Werner Lemberg <wl@gnu.org> Fix Savannah bug #28395. * src/truetype/ttdriver.c (Load_Glyph), src/type1/t1gload.c (T1_Load_Glyph): Don't check `num_glyphs' if incremental interface is used. 2010-01-05 Ken Sharp <ken.sharp@artifex.com> Make Type 1 `seac' operator work with incremental interface. This fixes Savannah bug #28480. * src/psaux/t1decode.c (t1operator_seac): Don't check `glyph_names' if incremental interface is used. 2010-01-04 Ken Sharp <ken.sharp@artifex.com> Make incremental interface work with TrueType fonts. This fixes Savannah bug #28478. * src/truetype/ttgload.c (load_truetype_glyph): Don't check `glyf_offset' if incremental interface is used. 2009-12-31 Lars Abrahamsson <wonko@opera.com> Make compilation with FT_CONFIG_OPTION_PIC work again. * src/base/ftglyph.c (FT_Glyph_To_Bitmap) [FT_CONFIG_OPTION_PIC]: Declare `library' for FT_BITMAP_GLYPH_CLASS_GET. * src/base/ftinit.c (ft_destroy_default_module_classes, ft_create_default_module_classes): Use proper casts (needed for C++ compilation). * src/sfnt/ttcmap.c (tt_cmap13_class_rec): Use FT_DEFINE_TT_CMAP. 2009-12-22 Marc Kleine-Budde <mkl@pengutronix.de> Make freetype-config aware of $SYSROOT. This is Savannah patch #7040. * builds/unix/freetype-config.in: Decorate with ${SYSROOT} where appropriate. 2009-12-20 Werner Lemberg <wl@gnu.org> Fix compiler warning. Reported by Sean. * src/base/ftdbgmem.c [!FT_DEBUG_MEMORY]: ANSI C doesn't like empty source files; however, some compilers warn about an unused variable declaration. This is now replaced with a typedef. 2009-12-18 Werner Lemberg <wl@gnu.org> Fix Savannah bug #28320. There exist corrupt, subsetted fonts (embedded in PDF files) which contain a private dict that ends with an unterminated floating point number (no operator following). We now ignore this error (as acrobat does). * src/cff/cffparse.c (cff_parser_run): Don't emit a syntax error for unterminated floating point numbers. 2009-12-16 Werner Lemberg <wl@gnu.org> Really fix compiler warnings. Reported by Sean. * src/truetype/ttgxvar.c (GX_PT_POINTS_ARE_WORDS, GX_PT_POINT_RUN_COUNT_MASK): Convert enum values to macros. 2009-12-16 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> Improve configure.raw to copy some options from CFLAGS to LDFLAGS. The linker of Mac OS X 10.6 is sensitive to the architecture. If the architectures are specified explicitly for the C compiler, the linker requires the architecture specifications too. * builds/unix/configure.raw: Replace `-isysroot' option parser by more generic argument parser. 2009-12-15 Werner Lemberg <wl@gnu.org> Fix compiler warnings. Reported by Sean. * src/truetype/ttgxvar.c (ft_var_readpackeddeltas): Fix counter data type. 2009-12-14 Ken Sharp <ken.sharp@artifex.com> Ignore invalid `setcurrentpoint' operations in Type 1 fonts. This fixes Savannah bug #28226. At least two wild PostScript files of unknown provenance contain Type 1 fonts, apparently converted from TrueType fonts in earlier PDF versions of the files, which use the `setcurrentpoint' operator inappropriately. FreeType currently throws an error in this case, but Ghostscript and Adobe Distiller both accept the fonts and ignore the problem. This commit #ifdefs out the check so PostScript interpreters using FreeType can render these files. The specification says `setcurrentpoint' should only be used to set the point after a `Subr' call, but these fonts use it to set the initial point to (0,0). Unnecessarily so, as they correctly use an `hsbw' operation which implicitly sets the initial point. * src/psaux/t1decode.c (t1_decoder_parse_charstrings) <op_setcurrentpoint>: Comment out code. 2009-12-14 Bram Tassyns <bramt@enfocus.be> Fix parsing of /CIDFontVersion.

The hash API in BDF driver is designed to be generic, it takes void * typed data. But BDF driver always gives an unsigned long integer (the index to a property). To reduce non-essential casts from unsigned long to void* and from void* to unsigned long, the hash API is changed to take size_t integer. The issue of incompatible cast between unsigned long and void* on LLP64 platform is reported by NightStrike from MinGW-Win64 project. See https://lists.gnu.org/archive/html/freetype/2009-09/msg00000.html * src/bdf/bdf.h: The type of hashnode->data is changed from void* to size_t. * src/bdf/bdflib.c (hash_insert): Get size_t data, instead of void* data.

The calculation of `vertBearingX' is not defined in the OTF font spec so FreeType does a `best effort' attempt. However, this value is defined in the PDF and PostScript specs, and that algorithm is better than the one FreeType currently uses: FreeType: Use the middle of the bounding box as the X coordinate of the vertical origin. Adobe PDF spec: Use the middle of the horizontal advance vector as the X coordinate of the vertical origin. FreeType's algorithm goes wrong if you have a really small glyph (like the full-width, circle-like dot at the end of the sentence, as used in CJK scripts) with large bearings. With the FreeType algorithm this dot gets centered on the baseline; with the PDF algorithm it gets the correct location (in the top right). Note that this is a serious issue, it's like printing the dot at the end of a Roman sentence at the center of the textline instead of on the baseline like it should. So i believe the PDF spec's algorithm should be used in FreeType as well. The `vertBearingY' value for such small glyphs is also very strange if no `vmtx' information is present, since the height of the bbox is not representable for the height of the glyph visually (the whitespace up to the baseline is part of the glyph). The fix also includes some code for a better estimate of `vertBearingY'. * src/base/ftobjs.c (ft_synthesize_vertical_metrics): `vertBearingX' is now calculated as described by the Adobe PDF Spec. Estimate for `vertBearingY' now works better for small glyphs completely above or below the baseline into account. * src/cff/cffgload.c (cff_slot_load): `vertBearingX' is now calculated as described by the Adobe PDF Spec. Vertical metrics information was always ignored when FT_CONFIG_OPTION_OLD_INTERNALS was not defined. * src/truetype/ttgload.c (compute_glyph_metrics): `vertBearingX' is now calculated as described by the Adobe PDF Spec. 2009-09-01 John Tytgat <John.Tytgat@esko.com> Fix custom cmap for empty Type 1 font (Savannah bug #27294). * include/freetype/internal/t1types.h (T1_EncodingRecRec_): Update comment to reflect revised code_last meaning. * src/type1/t1load.c (T1_Open_Face), src/type42/t42objs.c (T42_Open_Face): Assign max_char as highest character code + 1 and use this for T1_EncodingRecRec_::code_last. * src/psaux/t1cmap.c (t1_cmap_custom_init): Follow revised T1_EncodingRecRec_::code_last meaning. 2009-08-25 Werner Lemberg <wl@gnu.org> Fix rendering of horizontally compressed CFFs.

This fixes Savannah bug #26867. Previously, only integers have been used which can lead to serious rounding errors. However, fractional values are only used internally; after the charstrings (of either Type 1 or 2) have been processed, the resulting coordinates get rounded to integers currently -- before applying scaling. This should be fixed; at the same time a new load flag should be introduced, to be used in combination with FT_LOAD_NO_SCALE, which indicates that font units are returned in 16.16 format. Similarly, the incremental interface should be extended to allow fractional values for metrics. * include/freetype/internal/psaux.h (T1_BuilderRec): Remove `shift' field. * include/freetype/internal/pshints.h (T1_Hints_SetStemFunc, T1_Hints_SetStem3Func): Use FT_Fixed for coordinates. * src/psaux/psobjs.c: Include FT_INTERNAL_CALC_H.

Normally, the SCANMODE instruction (if present) to set the drop-out mode in a TrueType font is located in the `prep' table only and thus valid for all glyphs. However, there are fonts like `pala.ttf' which additionally contain this instruction in the hinting code of some glyphs (but not all). As a result it can happen that a composite glyph needs multiple drop-out modes for its subglyphs since the rendering state gets reset for each subglyph. FreeType collects the hinted outlines from all subglyphs, then it sends the data to the rasterizer. It also sends the drop-out mode -- after hinting has been applied -- and here is the error: It sends the drop-out mode of the last subglyph only; drop-out modes of all other subglyphs are lost. This patch fixes the problem; it adds a second, alternative mechanism to pass the drop-out mode: For each contour, the rasterizer now checks the first `tags' array element. If bit 2 is set, bits 5-7 contain the contour's drop-out mode, overriding the global drop-out mode. * include/freetype/ftimage.h (FT_CURVE_TAG_HAS_SCANMODE): New macro. * src/truetype/ttgload.c (TT_Hint_Glyph): Store drop-out mode in `tags[0]'. * src/raster/ftraster.c (Flow_Up, Overshoot_Top, Overshoot_Bottom): Use bits 3-5 instead of 0-2.

(Vertical_Sweep_Drop, Horizontal_Sweep_Drop, Horizontal_Gray_Sweep_Drop, Draw_Sweep): Use the profile's drop-out mode. 2009-06-16 Werner Lemberg <wl@gnu.org> Improve scan conversion rules 4 and 6. Two new constraints are introduced to better identify a `stub' -- a concept which is only vaguely described in the OpenType specification. The old code was too rigorous and suppressed more pixel than it should. . The intersection of the two profiles with the scanline is less than a half pixel. Code related to this was already present in the sources but has been commented out. . The endpoint of the original contour forming a profile has a distance (`overshoot') less than half a pixel to the scanline. Note that the two additional conditions fix almost all differences to the Windows rasterizer, but some problematic cases remain. * src/raster/ftraster.c (Overshoot_Top, Overshoot_Bottom): New macros for the `flags' field in the `TProfile' structure.

This patch fixes the following problems in ttsbit0.c: . Bitmaps for compound glyphs were never allocated. . `SBitDecoder' refused to load metrics if some other metrics have already been loaded. This condition certainly makes no sense for recursive calls, so I've just disabled it. Another possibility would be resetting `decoder->metrics_loaded' to false before loading each composite component. However, we must restore the original metrics after finishing the recursion; otherwise we can get a misaligned glyph. . `tt_sbit_decoder_load_bit_aligned' incorrectly handled `x_pos', causing some glyph components to be shifted too far to the right (especially noticeable for small sizes). Note that support for grayscale bitmaps (not necessarily compound) is completely broken in ttsbit0.c. * src/sfnt/tt_sbit_decoder_load_metrics: Always load metrics.

Fix return value for non-PFR fonts. Both problems reported by Chi Nguyen <chint@necsv.com>. 2008-12-21 anonymous FT_USE_MODULE declares things as: extern const FT_Module_Class (or similar for C++). However, the actual types of the variables being declared are often different, e.g., FT_Driver_ClassRec or FT_Renderer_Class. (Some are, indeed, FT_Module_Class.) This works with most C compilers (since those structs begin with an FT_Module_Class struct), but technically it's undefined behavior. To quote the ISO/IEC 9899:TC2 final committee draft, section 6.2.7 paragraph 2: All declarations that refer to the same object or function shall have compatible type; otherwise, the behavior is undefined. (And they are not compatible types.) Most C compilers don't reject (or even detect!) code which has this issue, but the GCC LTO development branch compiler does. (It outputs the types of the objects while generating .o files, along with a bunch of other information, then compares them when doing the final link-time code generation pass.)

Reported by Graham Asher. 2008-09-30 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * src/base/rules.mk: Add conditional source to BASE_SRC, for `make multi' on Mac OS X. If the macro $(ftmac_c) is defined, $(BASE_DIR)/$(ftmac_c) is added to BASE_SRC. In a normal build, the lack of ftmac.c in BASE_SRC is not serious because ftbase.c includes ftmac.c. * builds/unix/unix-def.in: Add a macro definition of $(ftmac_c). * builds/unix/configure.raw: Add procedure to set up appropriate value of $(ftmac_c) with the consideration of the availability of Carbon framework. 2008-09-30 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * src/base/Jamfile: Add target for multi build by jam on Mac OS X. * src/base/ftobjs.c (FT_New_Face): Fix the condition to include this function for MPW building. It is synchronized the condition to include ftmac.c source into ftbase.c. 2008-09-22 Werner Lemberg <wl@gnu.org> * src/cff/cffgload.c (CFF_Operator, cff_argument_counts, cff_decoder_parse_charstrings): Handle (invalid) `callothersubr' and `pop' instructions. 2008-09-22 John Tytgat <John.Tytgat@esko.com> Fix Savannah bug #24307. * include/freetype/internal/t1types.h (CID_FaceRec), src/type42/t42types.h (T42_FaceRec): Comment out `afm_data'. 2008-09-21 Werner Lemberg <wl@gnu.org> * src/smooth/ftgrays.c (gray_raster_render): Don't dereference `target_map' if FT_RASTER_FLAG_DIRECT is set.

(ft_lookup_PS_in_sfnt): New function to look up `TYP1' or `CID ' table in sfnt table directory. It is used before loading TrueType font driver. * docs/CHANGES: Add note about the current status of sfnt-wrapped Type1 and sfnt-wrapped CID-keyed font support. 2008-09-18 Werner Lemberg <wl@gnu.org> * src/base/ftsystem.c (FT_Done_Memory): Use ft_sfree directly for orthogonality (ft_free and ft_sfree could belong to different memory pools). This fixes Savannah bug #24297. 2008-09-18 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * src/cff/cffobjs.c (cff_face_init): Use TTAG_OTTO defined in tttags.h instead of numerical value 0x4F54544FL. 2008-09-16 Werner Lemberg <wl@gnu.org> * src/cff/cffgload.h, src/cff/cffgload.c (cff_decoder_set_width_only): Eliminate function call. 2008-09-15 George Williams <gww@silcom.com> Fix Savannah bug #24179, reported by Bram Tassyns. * src/type1/t1load.c (mm_axis_unmap, T1_Get_MM_Var): Fix computation of default values. 2008-09-15 Werner Lemberg <wl@gnu.org> * src/tools/glnames.py (main): Surround `ft_get_adobe_glyph_index' and `ft_adobe_glyph_list' with FT_CONFIG_OPTION_ADOBE_GLYPH_LIST to prevent unconditional definition. This fixes Savannah bug #24241. * src/psnames/pstables.h: Regenerated. 2008-09-13 Werner Lemberg <wl@gnu.org> * autogen.sh, builds/unix/configure.raw, include/freetype/config/ftconfig.h, builds/unix/ftconfig.in: Minor beautifying. * include/freetype/ftadvanc.h, include/freetype/ftgasp.h, include/freetype/ftlcdfil.h: Protect against FreeType 1.

(FT_USE_AUTOCONF_SIZEOF_TYPES): New macro. If defined, the cpp computation is disabled and the statically configured sizes are used. This fixes Savannah bug #21250. * builds/unix/configure.raw: Add the checks to compare the cpp computation results of the bit length of int and long versus the sizes detected by running `configure'. If the results are different, FT_USE_AUTOCONF_SIZEOF_TYPES is defined to prioritize the results. New option --{enable|disable}-biarch-config is added to define or undefine FT_USE_AUTOCONF_SIZEOF_TYPES manually. 2008-09-05 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * builds/unix/configure.raw: Clear FT2_EXTRA_LIBS when Carbon or ApplicationServices framework is missing. Although this value is not used in building of FreeType2, it is written in `freetype2.pc' and `freetype-config'. 2008-09-01 David Turner <david@freetype.org> * src/cache/ftccmap.c (FTC_CMapCache_Lookup): Accept a negative cmap index to mean `use default cached FT_Face's charmap'. This fixes Savannah bug #22625. * include/freetype/ftcache.h: Document it. Make FT_MulFix an inlined function. This is done to speed up FreeType a little (on x86 3% when loading+hinting, 10% when rendering, ARM savings are more important though). Disable this by undefining FT_CONFIG_OPTION_INLINE_MULFIX. Use of assembler code can now be controlled with FT_CONFIG_OPTION_NO_ASSEMBLER. * include/freetype/config/ftconfig.h, builds/unix/ftconfig.in [!FT_CONFIG_OPTION_NO_ASSEMBLER] (FT_MulFix_arm): New assembler implementation.

Add a new header named FT_ADVANCES_H declaring some new APIs to extract the advances of one or more glyphs without necessarily loading their outlines. Also provide `fast loaders' for the TrueType, Type1, and CFF font drivers (more to come later). * src/base/ftadvanc.c, include/freetype/ftadvanc.h: New files. * include/freetype/config/ftheader.h (FT_ADVANCES_H): New macro. * include/freetype/freetype.h (FT_LOAD_ADVANCE_ONLY): New macro. * include/freetype/internal/ftdriver.h (FT_Face_GetAdvancesFunc): `flags' and `advances' are now of type `FT_UInt' and `FT_Fixed', respectively. * src/base/Jamfile (_sources), src/base/rules.mk (BASE_SRC): Add ftadvanc.c. * src/cff/cffdrivr.c (cff_get_advances): New function.

(tt_driver_class): Register it. * src/truetype/ttgload.c (Get_HMetrics, Get_VMetrics): Renamed to... (TT_Get_HMetrics, TT_Get_VMetrics): This. Update callers. * src/truetype/ttgload.h: Declare them. * src/type1/t1gload.h, src/type1/t1gload.c (T1_Get_Advances): New function. * src/type1/t1driver.c (t1_driver_class): Register T1_Get_Advances. Add checks for minimum version of the `autotools' stuff. * autogen.sh: Implement it. (get_major_version, get_minor_version, get_patch_version, compare_to_minimum_version, check_tool_version): New auxiliary functions. * README.CVS: Document it. 2008-08-29 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * src/sfnt/sfobjs.c (sfnt_open_font): Use TTAG_OTTO defined in tttags.h instead of FT_MAKE_TAG( 'O', 'T', 'T', 'O' ). 2008-08-28 Werner Lemberg <wl@gnu.org> * src/type1/t1load.c (parse_encoding): Protect against infinite loop. This fixes Savannah bug #24150 (where a patch has been posted too). 2008-08-23 Werner Lemberg <wl@gnu.org> * src/type/t1afm.c (compare_kern_pairs), src/psaux/afmparse.c (afm_compare_kern_pairs): Fix comparison. This fixes Savannah bug #24119. 2008-08-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * src/base/ftobjs.c (FT_Stream_New): Initialize *astream always, even if passed library or arguments are invalid. This fixes a bug that an uninitialized stream is freed when an invalid library handle is passed. Originally proposed by Mike Fabian, 2008/08/18 on freetype-devel. (FT_Open_Face): Ditto (stream). (load_face_in_embedded_rfork): Ditto (stream2). 2008-08-18 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * src/base/ftmac.c: Add a fallback to guess the availability of the `ResourceIndex' type. It is used when built without configure (e.g., a build with Jam). * builds/mac/ftmac.c: Ditto. * builds/unix/configure.raw: Set HAVE_TYPE_RESOURCE_INDEX to 1 or 0 explicitly, even if `ResourceIndex' is unavailable. 2008-08-18 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * builds/unix/configure.raw: In checking of Mac OS X features, all-in-one header file `Carbon.h' is replaced by the minimum header file `CoreServices.h', similar to current src/base/ftmac.c. 2008-08-18 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * src/sfnt/ttcmap.c (tt_cmap2_validate): Skip the validation of sub-header when its code_count is 0. Many Japanese Dynalab fonts include such an empty sub-header (code_count == 0, first_code == 0 delta == 0, but offset != 0) as the second sub-header in SJIS cmap. 2008-08-04 Werner Lemberg <wl@gnu.org> * src/type1/t1tokens.h: Handle `ForceBold' keyword. This fixes Savannah bug #23995. * src/cid/cidload.c (parse_expansion_factor): New callback function. (cid_field_records): Use it for `ExpansionFactor'. * src/cod/cidtoken.h: Handle `ForceBold' keyword. Don't handle `ExpansionFactor'. 2008-08-04 Bram Tassyns <bramt@enfocus.be> * src/cff/cffparse.c (cff_parse_fixed_scaled): Fix thinko which resulted in incorrect scaling. This fixes Savannah bug #23973. 2008-08-04 Werner Lemberg <wl@gnu.org> Be more tolerant w.r.t. invalid entries in SFNT table directory. * src/sfnt/ttload.c (check_table_dir): Ignore invalid entries and adjust table count. Add more trace messages. (tt_face_load_font_dir): Updated. 2008-07-30 Werner Lemberg <wl@gnu.org> * src/cff/cffgload.c (cff_decoder_parse_charstrings): No longer assume that the first argument on the stack is the bottom-most element. Two reasons: o According to people from Adobe it is missing in the Type 2 specification that pushing of additional, superfluous arguments on the stack is prohibited. o Acroread in general handles fonts differently, namely by popping the number of arguments needed for a particular operand (as a PS interpreter would do). In case of buggy fonts this causes a different interpretation which of the elements on the stack are superfluous and which not. Since there are CFF subfonts (embedded in PDFs) which rely on Acroread's behaviour, FreeType now does the same. 2008-07-27 Werner Lemberg <wl@gnu.org> Add extra mappings for `Tcommaaccent' and `tcommaaccent'. This fixes Savannah bug #23940. * src/psnames/psmodule.c (WGL_EXTRA_LIST_SIZE): Rename to... (EXTRA_GLYPH_LIST_SIZE): This. Increase by 2. (ft_wgl_extra_unicodes): Rename to... (ft_extra_glyph_unicodes): This. Add two code values. (ft_wgl_extra_glyph_names): Rename to... (ft_extra_glyph_names): This. Add two glyphs. (ft_wgl_extra_glyph_name_offsets): Rename to... (ft_extra_glyph_name_offsets): This. Add two offsets. (ps_check_wgl_name, ps_check_wgl_unicode): Rename to... (ps_check_extra_glyph_name, ps_check_extra_glyph_unicode): This. Updated. (ps_unicodes_init): Updated. 2008-07-26 Werner Lemberg <wl@gnu.org> * src/cff/cffgload.c (cff_decoder_prepare, cff_decoder_parse_charstrings): Improve debug output. 2008-07-22 Martin McBride <mmcbride@emtex.com> * src/sfnt/ttcmap.c (tt_cmap4_validate, tt_cmap4_char_map_linear, tt_cmap4_char_map_binary): Handle fonts which treat the last segment specially. According to the specification, such fonts would be invalid but acroread accepts them. 2008-07-16 Jon Foster <Jon.Foster@cabot.co.uk> * src/pfr/pfrdrivr.c (pfr_get_advance): Fix off-by-one error. * src/base/ftcalc.c (FT_MulFix): Fix portability issue. * src/sfnt/ttpost.c (MAC_NAME) [!FT_CONFIG_OPTION_POSTSCRIPT_NAMES]: Fix compiler warning. 2008-07-16 Werner Lemberg <wl@gnu.org> Handle CID-keyed fonts wrapped in an SFNT (with cmaps) correctly. * src/cff/cffload.c (cff_font_load): Pass `pure_cff'. Invert sids table only if `pure_cff' is set. * src/cff/cffload.h: Updated. * src/cff/cffobjs.c (cff_face_init): Updated. Set FT_FACE_FLAG_CID_KEYED only if pure_cff is set. * docs/CHANGES: Updated. 2008-07-09 Werner Lemberg <wl@gnu.org> * src/truetype/ttpload.c (tt_face_load_loca): Handle buggy fonts where num_locations < num_glyphs. Problem reported by Ding Li. 2008-07-05 Werner Lemberg <wl@gnu.org> Since FreeType uses `$(value ...)', we now need GNU make 3.80 or newer. This fixes Savannah bug #23648. * configure: zsh doesn't like ${1+"$@"}. Update needed GNU make version. * builds/toplevel.mk: Check for `$(eval ...)'. * docs/INSTALL.GNU, docs/INSTALL.CROSS, docs/INSTALL.UNIX: Document it. 2008-07-04 Werner Lemberg <wl@gnu.org> * src/raster/ftraster.c (Draw_Sweep): If span is smaller than one pixel, only check for dropouts if neither start nor end point lies on a pixel center. This fixes Savannah bug #23762. 2008-06-29 Werner Lemberg <wl@gnu.org> * Version 2.3.7 released. ========================= Tag sources with `VER-2-3-7'. * docs/CHANGES, docs/VERSION.DLL: Update documentation and bump version number to 2.3.7. * README, Jamfile (RefDoc), builds/win32/visualc/index.html, builds/win32/visualc/freetype.dsp, builds/win32/visualc/freetype.vcproj, builds/win32/visualce/index.html, builds/win32/visualce/freetype.dsp, builds/win32/visualce/freetype.vcproj: s/2.3.6/2.3.7/, s/236/237/. * include/freetype/freetype.h (FREETYPE_PATCH): Set to 7. * builds/unix/configure.raw (version_info): Set to 9:18:3. * docs/release: Updated. 2008-06-28 Werner Lemberg <wl@gnu.org> * src/ftglyph.c (FT_Matrix_Multiply, FT_Matrix_Invert): Move to... * src/ftcalc.c: Here. This fixes Savannah bug #23729. 2008-06-27 Werner Lemberg <wl@gnu.org> * src/raster/ftraster.c (Vertical_Sweep_Drop, Horizontal_Sweep_Drop, Horizontal_Gray_Sweep_Drop): Test for intersections which degenerate to a single point can be ignored; this has been confirmed by Greg Hitchcock from Microsoft. (This was commented out code.) 2008-06-26 Werner Lemberg <wl@gnu.org> Improve navigation in API reference. * src/tools/docmaker/tohtml.py (html_header_3): Renamed to... (html_header_6): This. (html_header_3, html_header_3i, html_header_4, html_header_5, html_header_5t): New strings. (toc_footer_start, toc_footer_end): New strings. (HtmlFormatter::html_header): Updated. (HtmlFormatter::html_index_header, HtmlFormatter::html_toc_header): New strings. (HtmlFormatter::index_enter): Use `html_index_header'. (HtmlFormatter::index_exit): Print `html_footer'. (HtmlFormatter::toc_enter): Use `html_toc_header'. (HtmlFormatter::toc_exit): Print proper footer. Convert ~ to non-breakable space. * src/tools/docmaker/tohtml.py (make_html_para): Implement it. Update header files accordingly. 2008-06-24 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * builds/unix/configure.raw: Check type `ResourceIndex' explicitly and define HAVE_TYPE_RESOURCE_INDEX if it is defined. Mac OS X 10.5 bundles 10.4u SDK with MAC_OS_X_VERSION_10_5 macro but without ResourceIndex type definition. The macro does not inform the type availability. * src/base/ftmac.c: More parentheses are inserted to clarify the conditionals to disable legacy APIs in `10.5 and later' cases. If HAVE_TYPE_RESOURCE_INDEX is not defined, ResourceIndex is defined. 2008-06-24 Werner Lemberg <wl@gnu.org> * src/truetype/ttinterp.c (Ins_SCANTYPE): Don't check rendering mode. * src/raster/ftraster.c (Render_Glyph, Render_Gray_Glyph, Draw_Sweep): No-dropout mode is value 2, not value 0. (Draw_Sweep): Really skip dropout handling for no-dropout mode. 2008-06-24 Werner Lemberg <wl@gnu.org> * src/psaux/psobjs.c (t1_builder_close_contour): Don't add contour if it consists of one point only. Based on a patch from Savannah bug #23683 (from John Tytgat). 2008-06-22 Werner Lemberg <wl@gnu.org> * src/truetype/ttgload.c (TT_Load_Glyph): Protect bytecode stuff with IS_HINTED. * docs/CHANGES: Updated. 2008-06-22 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * builds/unix/configure.raw: If CFLAGS has `-isysroot XXX' option but LDFLAGS does not, import it to LDFLAGS. The option is used to specify non-default SDK on Mac OS X (e.g., universal binary SDK for Mac OS X 10.4 on PowerPC platform). Although Apple TechNote 2137 recommends to add the option only to CFLAGS, LDFLAGS should include it because libfreetype.la is built with -no-undefined. This fixes a bug reported by Ryan Schmidt in MacPorts, https://trac.macports.org/ticket/15331. 2008-06-21 Werner Lemberg <wl@gnu.org> Enable access to the various dropout rules of the B&W rasterizer. Pass dropout rules from the TT bytecode interpreter to the rasterizer. * include/freetype/ftimage.h (FT_OUTLINE_SMART_DROPOUTS, FT_OUTLINE_EXCLUDE_STUBS): New flags for FT_Outline. * src/raster/ftraster.c (Vertical_Sweep_Drop, Horizontal_Sweep_Drop, Horizontal_Gray_Sweep_Drop): Use same mode numbers as given in the OpenType specification. Fix mode 4 computation. (Render_Glyph, Render_Gray_Glyph): Handle new outline flags. * src/truetype/ttgload.c (TT_Load_Glyph) Convert scan conversion mode to FT_OUTLINE_XXX flags. * src/truetype/ttinterp.c (Ins_SCANCTRL): Enable ppem check. 2008-06-19 Werner Lemberg <wl@gnu.org> * src/cff/cffobjs.c (cff_face_init): Compute final `dict->units_per_em' value before assigning it to `cffface->units_per_EM'. Otherwise, CFFs without subfonts are scaled incorrectly if the font matrix is non-standard. This fixes Savannah bug #23630. * docs/CHANGES: Updated. 2008-06-19 Werner Lemberg <wl@gnu.org> * src/type/t1objs.c (T1_Face_Init): Slightly improve algorithm fix from 2008-06-19. 2008-06-18 Werner Lemberg <wl@gnu.org> * src/type/t1objs.c (T1_Face_Init): Fix change from 2008-03-21. Reported by Peter Weilbacher <mozilla@weilbacher.org>. * docs/CHANGES: Updated. 2008-06-15 George Williams <gww@silcom.com> * src/otvalid/otvgpos.c (otv_MarkBasePos_validate): Set `valid->extra2' to 1. This is undocumented in the OpenType 1.5 specification. 2008-06-15 Werner Lemberg <wl@gnu.org> * src/base/ftcalc.c (FT_MulFix) <asm>: Protect registers correctly from clobbering. Patch from Savannah bug report #23556. * docs/CHANGES: Document it. 2008-06-10 Werner Lemberg <wl@gnu.org> * autogen.sh: Add option `--install' to libtoolize. 2008-06-10 Werner Lemberg <wl@gnu.org> * Version 2.3.6 released. ========================= Tag sources with `VER-2-3-6'. * docs/CHANGES, docs/VERSION.DLL: Update documentation and bump version number to 2.3.6. * README, Jamfile (RefDoc), builds/win32/visualc/index.html, builds/win32/visualc/freetype.dsp, builds/win32/visualc/freetype.vcproj, builds/win32/visualce/index.html, builds/win32/visualce/freetype.dsp, builds/win32/visualce/freetype.vcproj: s/2.3.5/2.3.6/, s/235/236/. * include/freetype/freetype.h (FREETYPE_PATCH): Set to 6. * builds/unix/configure.raw (version_info): Set to 9:17:3. * include/freetype/internal/psaux.h (T1_BuilderRec): Remove `scale_x' and `scale_y'. * src/cff/cffgload.h (CFF_Builder): Remove `scale_x' and `scale_y'. * src/cff/cffparse.c: Include FT_INTERNAL_DEBUG_H. * src/cff/cffobjs.h: Include FT_INTERNAL_POSTSCRIPT_HINTS_H. 2008-06-10 Werner Lemberg <wl@gnu.org> * src/base/ftobjs.c (open_face): Check `clazz->init_face' and `clazz->done_face'. 2008-06-09 VaDiM <s_sliva@rambler.ru> Support debugging on WinCE. From Savannah patch #6536; this fixes bug #23497. * builds/win32/ftdebug.c (OutputDebugStringEx): New function/macro as a replacement for OutputDebugStringA (which WinCE doesn't have). Update all callers. (ft_debug_init) [_WIN32_CE]: WinCE apparently doesn't have environment variables. 2008-06-09 Werner Lemberg <wl@gnu.org> * README.CVS: Updated. * builds/unix/configure.raw, builds/unix/freetype-config.in: Updated for newer versions of autoconf and friends. 2008-06-08 Werner Lemberg <wl@gnu.org> * src/type1/t1parse.h (T1_ParserRec): Make `base_len' and `private_len' unsigned. * src/type1/t1parse.c (read_pfb_tag): Make `asize' unsigned and read it as such. (T1_New_Parser, T1_Get_Private_Dict): Make `size' unsigned. * src/base/ftstream.c (FT_Stream_Skip): Reject negative values. * src/type1/t1load.c (parse_blend_design_positions): Check `n_axis' for sane value. Fix typo. * src/psaux/psobjs.c (ps_table_add): Check `idx' correctly. * src/truetype/ttinterp (Ins_SHC): Use BOUNDS() to check `last_point'. * src/sfnt/ttload.c (tt_face_load_max_profile): Limit `maxTwilightPoints'. 2008-06-06 Werner Lemberg <wl@gnu.org> * src/truetype/ttinterp.c (Ins_IP): Handle case `org_dist == 0' correctly. This fixes glyphs `t' and `h' of Arial Narrow at 12ppem. 2008-06-03 Werner Lemberg <wl@gnu.org> * include/freetype/ftcache.h (FTC_FaceID): Change type back to FT_Pointer. Reported by Ian Britten <britten@caris.com>. 2008-06-02 Werner Lemberg <wl@gnu.org> Emit header info for defined FreeType objects in reference. * src/tools/docmaker/content.py (re_header_macro): New regexp. (ContentProcessor::__init__): Initialize new dictionary `headers'. (DocBlock::__init__): Collect macro header definitions. * src/tools/docmaker/tohtml.py (header_location_header, header_location_footer): New strings. (HtmlFormatter::__init__): Pass `headers' dictionary. (HtmlFormatter::print_html_field): Don't emit paragraph tags. (HtmlFormatter::print_html_field_list): Emit empty paragraph. (HtmlFormatter::block_enter): Emit header info. 2008-06-01 Werner Lemberg <wl@gnu.org> * include/freetype/config/ftheader.h (FT_UNPATENTED_HINTING_H, FT_INCREMENTAL_H): Added. 2008-05-28 Werner Lemberg <wl@gnu.org> * src/tools/docmaker/sources.py (SourceBlock::__init__): While looking for markup tags, return immediately as soon a single one is found. 2008-05-28 Werner Lemberg <wl@gnu.org> * src/truetype/ttinterp.c (Ins_MD): The MD instruction also uses original, unscaled input values. Confirmed by Greg Hitchcock from Microsoft. 2008-05-27 Werner Lemberg <wl@gnu.org> * src/tools/docmaker/tohtml.py (block_footer_start, block_footer_middle): Beautify output. 2008-05-25 Werner Lemberg <wl@gnu.org> * src/raster/ftraster.c (fc_black_render): Return 0 when we are trying to render into a zero-width/height bitmap, not an error code. * src/truetype/ttgload.c (load_truetype_glyph): Move initialization of the graphics state for subglyphs to... (TT_Hint_Glyph): This function. Hinting instructions for a composite glyph apparently refer to the just hinted subglyphs, not the unhinted, unscaled outline. This seems to fix Savannah bugs #20973 and (at least partially) #23310. 2008-05-20 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * src/base/ftmac.c (FT_New_Face_From_Suitcase): Check if valid `aface' is returned by FT_New_Face_From_FOND(). The patch was proposed by an anonymous reporter of Savannah bug #23204. 2008-05-18 Werner Lemberg <wl@gnu.org> * src/pshinter/pshalgo.c (ps_hints_apply): Reset scale values after correction for pixel boundary. Without this patch, the effect can be cumulative under certain circumstances, making glyphs taller and taller after each call. This fixes Savannah bug #19976. 2008-05-18 Werner Lemberg <wl@gnu.org> * src/base/ftdebug.c (FT_Message, FT_Panic): Send output to stderr. This fixes Savannah bug #23280. * docs/CHANGES: Updated. 2008-05-18 David Turner <david@freetype.org> * src/psnames/psmodule.c (ft_wgl_extra_unicodes, ft_wgl_extra_glyph_names, ft_wgl_extra_glyph_name_offsets, ps_check_wgl_name, ps_check_wgl_unicode): Use `static' to make declarations non-global. * src/type1/t1load.c: Add missing comment. 2008-05-17 Sam Hocevar <samh> * src/truetype/ttgload.c (TT_Load_Simple_Glyph): Handle zero-contour glyphs correctly. Patch from Savannah bug #23277. 2008-05-16 Werner Lemberg <wl@gnu.org> * docs/CHANGES: Updated. 2008-05-16 Sergey Tolstov <stolstov@esri.com> Improve support for WGL4 encoded fonts. * src/psnames/psmodule.c (WGL_EXTRA_LIST_SIZE): New macro. (ft_wgl_extra_unicodes, ft_wgl_extra_glyph_names, ft_wgl_extra_glyph_name_offsets): New arrays. (ps_check_wgl_name, ps_check_wgl_unicode): New functions. (ps_unicodes_init): Use them to add additional Unicode mappings. 2008-05-15 Werner Lemberg <wl@gnu.org> * src/psaux/t1decode.c (t1_decoder_parse_charstrings) <op_closepath>: `closepath' without a path is a no-op, not an error (cf. the PS reference manual). Reported by Martin McBride. 2008-05-15 Werner Lemberg <wl@gnu.org> * builds/toplevel.mk (CONFIG_GUESS, CONFIG_SUB): Updated. 2008-05-15 Werner Lemberg <wl@gnu.org> * src/type1/t1load.c (parse_subrs): Accept fonts with a subrs array which contains a single but empty entry. This is technically invalid (since it must end with `return'), but... Reported by Martin McBride. 2008-05-14 Werner Lemberg <wl@gnu.org> Finish fix of scaling bug of CID-keyed CFF subfonts. * include/freetype/internal/ftcalc.h, src/base/ftcalc.c (FT_Matrix_Multiply_Scaled, FT_Vector_Transform_Scaled): New functions. * src/cff/cffobjs.h (CFF_Internal): New struct. It is used to provide global hinting data for both the top-font and all subfonts (with proper scaling). * src/cff/cffobjs.c (cff_make_private_dict): New function, using code from `cff_size_init'. (cff_size_init, cff_size_done, cff_size_select, cff_size_request): Use CFF_Internal and handle subfonts. (cff_face_init): Handle top-dict and subfont matrices correctly; apply some heuristic in case of unlikely matrix concatenation results. This has been discussed with people from Adobe (thanks goes mainly to David Lemon) who confirm that the CFF specs are fuzzy and not correct. * src/cff/cffgload.h (cff_decoder_prepare): Add `size' argument. * src/cff/cffgload.c (cff_builder_init): Updated. (cff_decoder_prepare): Handle hints globals for subfonts. Update all callers. (cff_slot_load): Handling scaling of subfonts properly. * src/cff/cffparse.c (cff_parse_fixed_dynamic): New function. (cff_parse_font_matrix): Use it. * src/cff/cfftypes.h (CFF_FontDictRec): Make `units_per_em' FT_ULong. * docs/CHANGES: Document it. 2008-05-13 Werner Lemberg <wl@gnu.org> * src/winfonts/winfnt.c (fnt_face_get_dll_font, FNT_Face_Init): Handle case `face_index < 0'. * docs/CHANGES: Document it. 2008-05-04 Werner Lemberg <wl@gnu.org> First steps to fix the scaling bug of CID-keyed CFF subfonts, reported by Ding Li on 2008/03/28 on freetype-devel. * src/base/cff/cffparse.c (power_tens): New array. (cff_parse_real): Rewritten to introduce a fourth parameter which returns the `scaling' of the real number so that we have no precision loss. This is not used yet. Update all callers. (cff_parse_fixed_thousand): Replace with... (cff_parse_fixed_scaled): This function. Update all callers. 2008-05-03 Werner Lemberg <wl@gnu.org> * src/base/ftobjs.c (FT_Load_Glyph): Call the auto-hinter without transformation since it recursively calls FT_Load_Glyph. This fixes Savannah bug #23143. 2008-04-26 Werner Lemberg <wl@gnu.org> * include/freetype/internal/psaux.h (T1_BuilderRec): Mark `scale_x' and `scale_y' as obsolete since they aren't used. * src/psaux/psobjs.c (t1_builder_init): Updated. * src/cff/cffgload.h (CFF_Builder): Mark `scale_x' and `scale_y' as obsolete since they aren't used. * src/cff/cffgload.c (cff_builder_init): Updated. 2008-04-14 Werner Lemberg <wl@gnu.org> * src/pcf/pcfdrivr.c (PCF_Face_Init): Protect call to `FT_Stream_OpenLZW' with `FT_CONFIG_OPTION_USE_LZW'. From Savannah bug #22909. 2008-04-13 Werner Lemberg <wl@gnu.org> * src/psaux/psconv.c (PS_Conv_ToFixed): Increase precision if integer part is zero. 2008-04-01 Werner Lemberg <wl@gnu.org> Fix compilation with g++ 4.1 (with both `single' and `multi' targets). * src/base/ftobjs.c (FT_Open_Face): Don't define a variable in block which is crossed by a `goto'. * src/otvalid/otvalid.h (otv_MATH_validate): Add prototype. 2008-03-31 Werner Lemberg <wl@gnu.org> Fix support for subsetted CID-keyed CFFs. * include/freetype/freetype.h (FT_FACE_FLAG_CID_KEYED, FT_IS_CID_KEYED): New macros. * src/cff/cffobjs.c (cff_face_init): Set number of glyphs to the maximum CID value in CID-keyed CFFs. Handle FT_FACE_FLAG_CID_KEYED flag. * docs/CHANGES: Document it. Fix CFF font matrix calculation and improve precision. * src/cff/cffparse.c (cff_parse_real): Increase precision if integer part is zero. (cff_parse_font_matrix): Simplify computation of `units_per_em'; this prevents overflow also. Support FT_Get_CID_Registry_Ordering_Supplement for PS CID fonts. * src/cid/cidriver.c: Include FT_SERVICE_CID_H. (cid_get_ros): New function. (cid_service_cid_info): New service structure. (cid_services): Register it. 2008-03-23 Werner Lemberg <wl@gnu.org> Adjustments for Visual C++ 8.0, as reported by Rainer Deyke. * builds/compiler/visualc.mk (CFLAGS): Remove /W5. (ANSIFLAGS): Add _CRT_SECURE_NO_DEPRECATE. 2008-03-21 Laurence Darby <ldarby> * src/type1/t1objs.c (T1_Face_Init): Use `/Weight'. Patch from Savannah bug #22675. 2008-03-13 Derek Clegg <dclegg@apple.com> * src/truetype/ttgxvar.c (TT_Get_MM_Var): Fix named style loop. Patch from Savannah bug #22541. 2008-03-03 Masatoshi Kimura <VYV03354@nifty.ne.jp> * src/sfnt/ttcmap.c (tt_cmap14_char_map_nondef_binary, tt_cmap14_find_variant): Return correct value. (tt_cmap14_variant_chars): Fix check for `di'. 2008-02-29 Werner Lemberg <wl@gnu.org> * docs/CHANGES: Updated. 2008-02-29 Wolf Add build support for symbian platform. From Savannah bug #22440. * builds/symbian/*: New files. 2008-02-21 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * src/base/ftmac.c (parse_fond): Fix a bug of PostScript font name synthesis. For any face of a specified FOND, always the name for the first face was used. Except of a FOND that refers multiple Type1 font files, wrong synthesized font names are not used at all, so this is an invisible bug. A few limit checks are added too. * builds/mac/ftmac.c: Ditto. 2008-02-21 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * builds/unix/configure.raw: Split compiler option to link Carbon frameworks to one option for CoreServices framework and another option for ApplicationServices framework. The split options can be managed by GNU libtool to avoid unrequired duplication when FreeType is linked with other applications. Suggested by Daniel Macks, Savannah bug #22366. 2008-02-18 Victor Stinner <victor.stinner@haypocalc.com> * src/truetype/ttinterp.c (Ins_IUP): Check number of points. Fix from Savannah bug #22356. 2008-02-17 Jonathan Blow <jon@number-none.com> * src/autofit/afloader.c (af_loader_load_g, af_loader_load_glyph): Check for valid callback pointers. 2008-02-15 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * src/base/ftmac.c (FT_New_Face_From_SFNT): Check the sfnt resource handle by its value instead of ResError(), fix provided by Deron Kazmaier. According to the Resource Manager Reference, GetResource(), Get1Resource(), GetNamedResource(), Get1NamedResource() and RGetResource() set noErr but return NULL handle when they can not find the requested resource. These functions never return undefined values, so it is sufficient to check if the handle is not NULL. * builds/mac/ftmac.c (FT_New_Face_From_SFNT): Ditto. 2008-02-14 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * src/base/ftbase.c: <ftmac.c> is replaced by "ftmac.c" as other inclusion styles. Now it always includes src/base/ftmac.c; builds/mac/ftmac.c is never included in any configuration. * builds/unix/configure.raw: Print warning if configure is executed with options to specify Carbon functionalities explicitly. * docs/INSTALL.MAC: Note that legacy builds/mac/ftmac.c is not included automatically and manual replacement is required. 2008-02-11 Werner Lemberg <wl@gnu.org> * builds/modules.mk (CLOSE_MODULE, REMOVE_MODULE), builds/detect.mk (dos_setup), builds/freetype.mk (clean_project_dos, distclean_project_dos): Don't use \ but $(SEP).

Reported by Allan Yang. 2008-01-12 Werner Lemberg <wl@gnu.org> * src/raster/ftraster.c (FT_CONFIG_OPTION_5_GRAY_LEVELS): Remove. 2008-01-12 Allan Yang, Jian Hua - SH <Allan.Yang@fmc.fujitsu.com> * src/raster/ftraster.c (ft_black_init) [FT_RASTER_OPTION_ANTI_ALIASING]: Fix compilation. 2008-01-10 Werner Lemberg <wl@gnu.org> * src/truetype/ttgload.c (load_truetype_glyph): Handle the case where the number of contours in a simple glyph is zero (and which does contain an entry in the `glyf' table). This fixes Savannah bug #21990. 2008-01-04 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> Formatting suggested by Sean McBride. * builds/mac/ftmac.c: Formatting (tab expanded). * src/autofit/afindic.c: Ditto. * src/base/ftcid.c: Ditto. * src/base/ftmac.c: Ditto. 2007-12-30 Werner Lemberg <wl@gnu.org> * src/smooth/ftgrays.c (gray_raster_render): Check `outline' correctly. 2007-12-21 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> Improvement of POSIX resource-fork accessor to load unsorted references in a resource. In HelveLTMM (resource-fork PostScript Type1 font bundled with Mac OS X since 10.3.x), the appearance order of PFB chunks is not sorted; sorting the chunks by reference IDs is required. * include/freetype/internal/ftrfork.h (FT_RFork_Ref): New structure type to store a pair of reference ID and offset to the chunk. * src/base/ftrfork.c (ft_raccess_sort_ref_by_id): New function to sort FT_RFork_Ref by their reference IDs. (FT_Raccess_Get_DataOffsets): Returns an array of offsets that is sorted by reference ID. 2007-12-14 Werner Lemberg <wl@gnu.org> * src/cff/cffparse.c (cff_parse_real): Don't apply `power_ten' division too early; otherwise the most significant digit(s) of the final result are lost as the value is truncated to an integer. This fixes Savannah bug #21794 (where the patch has been posted too). 2007-12-06 Fix <4d876b82@gmail.com> Pass options from one configure script to another as-is (not expanded). This is needed for options like --includedir='${prefix}/include'. * builds/unix/detect.mk, configure: Prevent argument expansion in call to the (real) `configure' script. 2007-12-06 Werner Lemberg <wl@gnu.org> * src/truetype/ttgload.c (load_truetype_glyph): Fix compilation if TT_USE_BYTECODE_INTERPRETER isn't defined. 2007-12-06 Werner Lemberg <wl@gnu.org> There exist CFFs which contain opcodes for the Type 1 operators `hsbw' and `closepath' which are both invalid in Type 2 charstrings. However, it doesn't harm to support them. * src/cff/cffgload.c (CFF_Operator): Add `cff_op_hsbw' and `cff_op_closepath.' (cff_argument_counts): Ditto. (cff_decoder_parse_charstrings): Handle Type 1 opcodes 9 (closepath) and 13 (hsbw) which are invalid in Type 2 charstrings. 2007-12-06 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * src/base/ftrfork.c (raccess_guess_darwin_newvfs): New function to support new pathname syntax `..namedfork/rsrc' to access a resource fork on Mac OS X. The legacy syntax `/rsrc' does not work on case-sensitive HFS+. (raccess_guess_darwin_hfsplus): Fix a bug in the calculation of buffer size to store a pathname. * include/freetype/internal/ftrfork.h: Increment the number of resource fork guessing rule. 2007-12-06 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * builds/unix/configure.raw: Improve the compile tests to search Carbon functions. * builds/mac/ftmac.c: Import fixes for Carbon incompatibilities proposed by Sean McBride from src/base/ftmac.c (see 2007-11-16). 2007-12-06 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> The documents and comments for Mac OS X are improved by Sean McBride. * src/base/ftmac.c: Fix a comment. * include/freetype/ftmac.h: Ditto. * docs/INSTALL.MAC: Improve English and add comment on lowest system version specified by MACOSX_DEPLOYMENT_TARGET. 2007-12-04 Werner Lemberg <wl@gnu.org> * src/cff/cffload.c (cff_subfont_load): Don't use logical OR to concatenate error codes. * src/sfnt/ttsbit.c (Load_SBit_Range): Ditto. 2007-12-04 Graham Asher <graham.asher@btinternet.com> * src/truetype/ttobjs.c (tt_face_init): Don't use logical OR to concatenate error codes. 2007-12-04 Sean McBride <sean@rogue-research.com> * src/pfr/pfrgload.c (pfr_glyph_load_compound): Remove compiler warning. 2007-11-20 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> Fix MacOS legacy font support by Masatake Yamato on Mac OS X. It is not working since 2.3.5. In FT_Open_New(), if FT_New_Stream() cannot mmap() the specified file and cannot seek to head of the specified file, it returns NULL stream and FT_Open_New() returns the error immediately. On MacOS, most legacy MacOS fonts fall into such a scenario because their data forks are zero-sized and cannot be sought. To proceed to guessing of resource fork fonts, the functions for legacy MacOS font must properly handle the NULL stream returned by FT_New_Stream(). * src/base/ftobjs.c (IsMacBinary): Return error FT_Err_Invalid_Stream_Operation immediately when NULL stream is passed. (FT_Open_Face): Even when FT_New_Stream() returns an error, proceed to fallback. Originally, legacy MacOS font is tested in the cases of FT_Err_Invalid_Stream_Operation (occurs when data fork is empty) or FT_Err_Unknown_File_Format (occurs when AppleSingle header or .dfont header is combined). Now the case of FT_Err_Cannot_Open_Stream is included. * src/base/ftrfork.c (FT_Raccess_Guess): When passed stream is NULL, skip FT_Stream_Seek(), which seeks to the head of stream, and proceed to unit testing of raccess_guess_XXX(). FT_Stream_Seek() for a NULL stream causes a Bus error on Mac OS X. (raccess_guess_apple_double): Return FT_Err_Cannot_Open_Stream immediately if passed stream is NULL. (raccess_guess_apple_single): Ditto. 2007-11-16 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> Fix for Carbon incompatibilities since Mac OS X 10.5, proposed by Sean McBride. * doc/INSTALL.MAC: Comment on MACOSX_DEPLOYMENT_TARGET. * include/freetype/ftmac.h: Deprecate FT_New_Face_From_FOND and FT_GetFilePath_From_Mac_ATS_Name. Since Mac OS X 10.5, calling Carbon functions from a forked process is classified as unsafe by Apple. All Carbon-dependent functions should be deprecated. * src/base/ftmac.c: Use essential header files <CoreServices/CoreServices.h> and <ApplicationServices/ApplicationServices.h> instead of all-in-one header file <Carbon/Carbon.h>. Include <sys/syslimits.h> and replace HFS_MAXPATHLEN by Apple genuine macro PATH_MAX. Add fallback macro for kATSOptionFlagsUnRestrictedScope which is not found in Mac OS X 10.0. Multi-character constants ('POST', 'sfnt' etc) are replaced by 64bit constants calculated by FT_MAKE_TAG() macro. For the index in the segment of resource fork, new portable type ResourceIndex is introduced for better compatibility. This type is since Mac OS X 10.5, so it is defined as short when built on older platforms. (FT_ATSFontGetFileReference): If build target is only the systems 10.5 and newer, it calls Apple genuine ATSFontGetFileReference(). (FT_GetFile_From_Mac_ATS_Name): Return an error if system is 10.5 and newer or 64bit platform, because legacy type FSSpec type is removed completely. (FT_New_Face_From_FSSpec): Ditto. 2007-11-01 Werner Lemberg <wl@gnu.org> * src/sfnt/sfobjs.c (sfnt_done_face): Check `sfnt' everywhere. This fixes Savannah bug #21485. 2007-10-29 Daniel Svoboda <dasvo@planeta@cz> * src/winfonts/winfnt.c (FNT_Face_Init): Check first that the driver can handle the font at all, then check `face_index'. Otherwise, the driver might return the wrong error code. This fixes Savannah bug #21468. 2007-10-21 Werner Lemberg <wl@gnu.org> * src/sfnt/sfobjs.c (sfnt_load_face): Support bit 9 and prepare support for bit 8 of the `fsSelection' field in the `OS/2' table. MS is already using this; hopefully, this becomes part of OpenType 1.5. Prepare also support for `name' IDs 21 (WWS_FAMILY) and 22 (WWS_SUBFAMILY). 2007-10-20 Werner Lemberg <wl@gnu.org> * src/tools/docmaker/tohtml.py (html_header_2): Fix typo. Add `td.left' element to CSS. (toc_section_enter): Use it. 2007-10-18 David Turner <david@freetype.org> * include/freetype/freetype.h, src/base/ftobjs.c: Rename API functions related to cmap type 14 support to the `FT_Object_ActionName' scheme: FT_Get_Char_Variant_Index -> FT_Face_GetCharVariantIndex FT_Get_Char_Variant_IsDefault -> FT_Face_GetCharVariantIsDefault FT_Get_Variant_Selectors -> FT_Face_GetVariantSelectors FT_Get_Variants_Of_Char -> FT_Face_GetVariantsOfChar FT_Get_Chars_Of_Variant -> FT_Face_GetCharsOfVariant Update documentation accordingly. * src/sfnt/ttcmap.c: Stronger cmap 14 validation. Make the code a little more consistent with FreeType coding conventions and modify the cmap14 functions that returned a newly allocated array to use a persistent vector from the TT_CMap14 object instead. (TT_CMap14Rec): Provide array and auxiliary data for result. (tt_cmap14_done, tt_cmap14_ensure): New functions. (tt_cmap14_init, tt_cmap14_validate, tt_cmap14_char_map_def_binary, tt_cmap14_char_map_nondef_binary, tt_cmap14_find_variant, tt_cmap14_char_var_index, tt_cmap14_variants, tt_cmap14_char_variants, tt_cmap14_def_char_count, tt_cmap14_get_def_chars, tt_cmap14_get_nondef_chars, tt_cmap14_variant_chars, tt_cmap14_class_rec): Updated and improved. 2007-10-15 George Williams <gww@silcom.com> Add support for cmap type 14. * devel/ftoption.h, include/freetype/config/ftoption.h (TT_CONFIG_CMAP_FORMAT_14): New macro. * include/freetype/internal/ftobjs.h (FT_CMap_CharVarIndexFunc, FT_CMap_CharVarIsDefaultFunc, FT_CMap_VariantListFunc, FT_CMap_CharVariantListFunc, FT_CMap_VariantCharListFunc): New support function prototypes. (FT_CMap_ClassRec): Add them. Update all users. * include/freetype/ttnameid.h (TT_APPLE_ID_VARIANT_SELECTOR): New macro. * include/freetype/freetype.h (FT_Get_Char_Variant_Index, FT_Get_Char_Variant_IsDefault, FT_Get_Variant_Selectors, FT_Get_Variants_Of_Char, FT_Get_Chars_Of_Variant): New API functions. * src/base/ftobjs.c (find_variant_selector_charmap): New auxiliary function.

(FT_Get_Char_Variant_Index, FT_Get_Char_Variant_IsDefault, FT_Get_Variant_Selectors, FT_Get_Variants_Of_Char, FT_Get_Chars_Of_Variant): New API functions. * src/sfnt/ttcmap.c (TT_PEEK_UINT24, TT_NEXT_UINT24): New macros. (TT_CMap14Rec, tt_cmap14_init, tt_cmap14_validate, tt_cmap14_char_index, tt_cmap14_char_next, tt_cmap14_get_info, tt_cmap14_char_map_def_binary, tt_cmap14_char_map_nondef_binary, tt_cmap14_find_variant, tt_cmap14_char_var_index, tt_cmap14_char_var_isdefault, tt_cmap14_variants, tt_cmap14_char_variants, tt_cmap14_def_char_count, tt_cmap14_get_def_chars, tt_cmap14_get_nondef_chars, tt_cmap14_variant_chars, tt_cmap14_class_rec): New functions and structures for cmap 14 support. (tt_cmap_classes): Register tt_cmap14_class_rec. (tt_face_build_cmaps): One more error message. * docs/CHANGES: Mention cmap 14 support. 2007-10-01 Werner Lemberg <wl@gnu.org> * src/base/ftobjs.c (find_unicode_charmap): If search for a UCS-4 charmap fails, do the loop again while searching a UCS-2 charmap. This favours MS charmaps over Apple ones. 2007-08-29 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * src/base/ftmac.c: Introduction of abstract `short' data types, ResFileRefNum and ResID. These types were introduced for Copland, then backported to MPW. The variables exchanged with FileManager QuickDraw frameworks are redefined by these data types.

This should give us more time to tune and improve the warper for the next release. * docs/CHANGES: Update accordingly. 2007-01-25 David Turner <david@freetype.org> For light auto-hinting, improve glyph advance widths and resurrect normal/full hinting to its normal quality. * src/autofit/afhints.h (AF_GlyphHintsRec): New members `xmin_delta' and `xmax_delta'. * src/autofit/afhints.c (af_glyph_hints_reload): Reset `xmin_delta' and `xmax_delta'. * src/autofit/afloader.c (af_loader_load_g) <AF_USE_WARPER>: Replace preprocessor conditional with if-clause, handling both light and normal mode. * src/autofit/afwarp.c (AF_WarpScore): Fine-tune again.

(tt_size_init): Move most code into `tt_size_init_bytecode'. (tt_size_done): Move most code into `tt_size_done_bytecode'. (tt_size_reset): Move some code to `tt_size_ready_bytecode'. Don't extract the metrics table from the SFNT font file. Instead, reparse it on each glyph load. The runtime difference is not noticeable, and it can save a lot of heap memory when memory-mapped files are not used. * include/freetype/internal/tttypes.h (TT_FaceRec): Add members `horz_metrics_offset' and `vert_metrics_offset'. * src/sfnt/ttmtx.c (tt_face_load_hmtx, tt_face_get_metrics): Updated. * src/sfnt/ttcmap.c (tt_cmap4_validate): Slight optimization. Do not load the CFF index offsets into memory, since this wastes a *lot* of heap memory with large Asian CFF fonts. There is no significant performance loss. * src/cff/cffload.h: Add `cff_charset_cid_to_gindex' declaration. * src/cff/cfftypes.h (CFF_IndexRec): Add fields `start' and `data_size'. (CFF_CharsetRec): Add field `num_glyphs'. * src/cff/cffload.c (cff_index_read_offset, cff_index_load_offsets, cff_charset_cid_to_gindex): New functions. (cff_new_index): Renamed to... (cff_index_init): This. Update all callers. Updated -- some code has been moved to `cff_index_load_offsets'. (cff_done_index): Renamed to... (cff_index_done): This. Update all callers. (cff_index_get_pointers, cff_index_access_element): Updated to use stream offsets. (cff_charset_compute_cids): Set `num_glyphs' field. (cff_encoding_load): Updated. * src/cff/cffgload.c (cff_slot_load): Updated. 2007-01-04 David Turner <david@freetype.org> * docs/INSTALL.UNIX: Simplify some parts, add reference to autogen.sh and pointer to README.CVS. * README.CVS: Add common problem description and solution when running autogen.sh. * docs/INSTALL: Add reference to MacOS X. * docs/MAKEPP, docs/INSTALL.MAC: New documentation files. * docs/TODO: Remove obsolete items. * src/raster/ftraster.c: (TRaster_Instance): Replace it with... (TWorker): This. Remove `count_table' and `memory'. Make `grays' a pointer. (TRaster): New structure. (count_table): New static array. (RAS_ARGS, RAS_ARG, RAS_VARS, RAS_VAR, FT_UNUSED_RASTER, cur_ras, Vertical_Gray_Sweep_Step, ft_black_new, ft_black_done, ft_black_set_mode, ft_black_render): Updated. (ft_black_init): Don't initialize `count_table'. (ft_black_reset): Use the render pool. This saves about 6KB of heap space for each FT_Library instance. * src/smooth/ftgrays.c (TRaster): Replaced with... (TWorker): This. Remove `memory'. (TRaster): New structure. (RAS_ARG_, RAS_ARG, RAS_VAR_, RAS_VAR, ras, gray_render_line, gray_move_to, gray_line_to, gray_conic_to, gray_cubic_to, gray_render_span, gray_raster_render): Updated. (gray_raster_reset): Use the render pool. This saves about 6KB of heap space for each FT_Library instance. * src/sfnt/sfobjs.c, src/sfnt/ttkern.c, src/sfnt/ttkern.h, src/sfnt/ttmtx.c, src/sfnt/ttsbit.c, src/sfnt/ttsbit.h, src/truetype/ttpload.c, include/freetype/config/ftoption.h: Remove FT_OPTIMIZE_MEMORY macro (and code for !FT_OPTIMIZE_MEMORY) since the optimization is no longer experimental. * src/pshinter/pshalgo.c (psh_glyph_interpolate_normal_points): Remove a typo that results in no hinting and a memory leak with some large Asian CFF fonts. * src/base/ftobjs.c (FT_Done_Library): Remove a subtle memory leak which happens when FT_Done_Library is called with still opened CFF_Faces in it. We need to close all faces before destroying the modules, or else some bad things (memory leaks) may happen. 2007-01-02 Werner Lemberg <wl@gnu.org> * src/gxvalid/gxvkern.c (gxv_kern_subtable_fmt0_pairs_validate): Remove compiler warning. 2007-01-02 David Turner <david@freetype.org> * src/sfnt/sfobjs.c: Add documentation comment. 2006-12-31 Masatake YAMATO <jet@gyve.org> * src/gxvalid/gxvkern.c (gxv_kern_subtable_fmt0_pairs_validate): New function.

When explicit switches for FSSpec/FSRef/QuickDraw/ATS availability are given to configure, builds/mac/ftmac.c is used instead of default src/base/ftmac.c. 2006-12-15 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * builds/mac/ftmac.c: Copied src/base/ftmac.c for legacy system. * builds/mac/FreeType.m68k_cfm.make.txt: Fix to use builds/mac/ftmac.c instead of src/base/ftmac.c * builds/mac/FreeType.ppc_carbon.make.txt: Ditto. * builds/mac/FreeType.ppc_classic.make.txt: Ditto. * builds/mac/FreeType.m68k_far.make.txt: Ditto, and exclude gxvalid.c that cannot be built at present. 2006-12-15 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * src/base/ftobjs.c: Improvement of resource fork handler for POSIX, cf. https://lists.gnu.org/archive/html/freetype-devel/2006-10/msg00025.html (Mac_Read_sfnt_Resource): Count only `sfnt' resource of suitcase font format or .dfont, to simulate the face index number counted by ftmac.c. (IsMacResource): Return the number of scalable faces correctly. 2006-12-10 Werner Lemberg <wl@gnu.org> * builds/toplevel.mk (version): Protect against `distclean' target. 2006-12-09 Werner Lemberg <wl@gnu.org> * builds/*/*def.mk, builds/*/detect.mk (CAT): Define to either `cat' or `type'. * builds/freetype.mk (version): Extracted from freetype.h, using GNU make's built-in string functions. (refdoc): Use $(version) instead of static version number. 2006-12-08 Werner Lemberg <wl@gnu.org> * builds/toplevel.mk (dist): Extract version number from freetype.h. 2006-12-08 Vladimir Volovich <vvv@vsu.ru> * src/tools/apinames.c (State): Remove final comma in structure -- xlc v5 under AIX 4.3 doesn't like this. 2006-12-07 David Turner <david@freetype.org> * src/autofit/afloader.c (af_loader_load_g): Small adjustment to the spacing of auto-fitted glyphs. This only impacts rare cases (e.g., Arial Bold at rather small character sizes). 2006-12-03 Werner Lemberg <wl@gnu.org> * src/sfnt/rules.mk (SFNT_DRV_SRC): Add ttsbit0.c. 2006-12-01 Werner Lemberg <wl@gnu.org> * src/sfnt/sfobjs.c (tt_face_get_name): All Unicode strings are encoded in UTF-16BE.

Improve handling of remaining edges. 2006-11-22 Werner Lemberg <wl@gnu.org> Fix Savannah bug #15553. * src/truetype/ttgload.c (tt_loader_init): Re-execute the CVT program after a change from mono to grayscaling (and vice versa). Use correct constant for comparison to get `exec->grayscale'. 2006-11-18 Werner Lemberg <wl@gnu.org> Because FT_Load_Glyph expects CID values for CID-keyed fonts, the test for a valid glyph index must be deferred to the font drivers. This patch fixes Savannah bug #18301. * src/base/ftobjs.c (FT_Load_Glyph): Don't check `glyph_index'. * src/bdf/bdfdrivr.c (BDF_Glyph_Load), src/cff/cffgload.c (cff_slot_load), src/cid/cidgload.c (cid_slot_load_glyph), src/pcf/pcfdrivr.c (PCF_Glyph_Load), src/pfr/pfrobjs.c (pfr_slot_load), src/truetype/ttdriver.c (Load_Glyph), src/type1/t1gload.c (T1_Load_Glyph), src/winfonts/winfnt.c (FNT_Load_Glyph): Check validity of `glyph_index'. 2006-11-13 David Turner <david@freetype.org> * src/truetype/ttinterp.c (FIX_BYTECODE): Undefine. The interpreter `enhancements' are still too buggy for general use. * src/base/ftlcdfil.c: Add support for FT_FORCE_LIGHT_LCD_FILTER and FT_FORCE_LEGACY_LCD_FILTER at compile time. Define these macros when building the library to change the default LCD filter to be used. This is only useful for experimentation. * include/freetype/ftlcdfil.h: Update documentation. 2006-11-10 David Turner <david@freetype.org> * src/smooth/ftsmooth.c: API change for the LCD filter.

(Ins_IUP): Fix computation of `end_point'. 2006-06-22 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> Insert EndianS16_BtoN and EndianS32_BtoN as workaround for Intel Mac. The original patch was written by David Sachitano and Lawrence Coopet, and modified by Sean McBride for MPW compatibility. Only required data are converted; unused data are left in big endian. * src/base/ftmac.c: Include <Endian.h> for byteorder macros for non Mac OS X platforms. (OS_INLINE): Undefine before definition. (count_faces_sfnt): Insert EndianS16_BtoN to parse the header of FontAssociation table in FOND resource. (count_faces_scalable): Insert EndianS16_BtoN to parse the header and fontSize at each entry of FontAssociation table in FOND resource. (parse_fond): Insert EndianS16_BtoN and EndianS32_BtoN to parse ffStylOff of FamilyRecord header of FOND resource, the header, fontSize, fontID at each entry of FontAssociation table, and StyleMapping table. (count_faces): Call `HUnlock' after all FOND utilization. 2006-06-08 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> Public API of TrueTypeGX, OpenType, and classic kern table validator should return `FT_Err_Unimplemented_Feature' if validation service is unavailable (disabled in `modules.cfg'). It is originally suggested by David Turner, cf. https://lists.gnu.org/archive/html/freetype-devel/2005-11/msg00078.html * src/base/ftgxval.c (FT_TrueTypeGX_Validate): Return FT_Err_Unimplemented_Feature if TrueTypeGX validation service is unavailable. (FT_ClassicKern_Validate): Return FT_Err_Unimplemented_Feature if classic kern table validation service is unavailable. * src/base/ftotval.c (FT_OpenType_Validate): Return FT_Err_Unimplemented_Feature if OpenType validation service is unavailable. 2006-06-08 Werner Lemberg <wl@gnu.org> * src/bdf/bdflib.c (bdf_load_font): Fix memory leaks in case of errors. 2006-06-07 David Turner <david@freetype.org> * src/type1/t1afm.c (KERN_INDEX): Make it more robust. (T1_Read_Metrics): Fix memory leak which happened when the metrics file doesn't have kerning pairs. This fixes Savannah bug #16768. 2006-06-06 David Turner <david@freetype.org> Fix memory leak described in Savannah bug #16759. We change `ps_unicodes_init' so that it also takes a `free_glyph_name' callback to release the glyph names returned by `get_glyph_name' * include/freetype/internal/services/svpscmap.h (PS_Glyph_NameFunc): Renamed to ... (PS_GetGlyphNameFunc): This. (PS_FreeGlyphNameFunc): New typedef. (PS_Unicodes_InitFunc): Add variable for PS_FreeGlyphNameFunc. * src/cff/cffcmap.c (cff_sid_to_glyph_name): Use `TT_Face' for first argument. (cff_sid_free_glyph_name): New function. (cff_cmap_unicode_init): Updated. * src/psaux/t1cmap.c (t1_cmap_unicode_init): Updated. * src/psnames/psmodule.c (ps_unicodes_init): Add variable for PS_FreeGlyphNameFunc and use it. 2006-06-04 David Turner <david@freetype.org> * src/base/ftutil.c (ft_mem_qrealloc): Fix the function to accept `item_size == 0' as well -- though this sounds weird, it can theoretically happen. This fixes Savannah bug #16669. * src/pfr/pfrobjs.c (pfr_face_init): Fix the computation of `face->num_glyphs' which missed the last glyph, due to the offset-by-1 computation, since the PFR format doesn't guarantee that glyph index 0 corresponds to the `missing glyph. This fixes Savannah bug #16668. 2006-05-25 Werner Lemberg <wl@gnu.org> * builds/unix/unix-cc.in (LINK_LIBRARY): Don't comment out `-no-undefined'. Reported by Christian Biesinger. 2006-05-19 Brian Weed <bw@imaginengine.com> * builds/win32/visualc/freetype.dsp: Release libraries no longer have debug information, and debug libraries use `C7 compatible' debug info. 2006-05-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> Apply patch by Derek Clegg to fix two memory leaks in the MacOS resource fork handler. This fixes Savannah bug #16631. * src/base/ftobjs.c (load_face_in_embedded_rfork): Replace `FT_Stream_Close' by `FT_Stream_Free' to fix memory leak. * src/base/ftrfork.c (raccess_guess_linux_double_from_file_name): Replace `FT_Stream_Close' by `FT_Stream_Free' to fix memory leak. 2006-05-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * build/unix/configure.raw: Add a fallback to disable Carbon dependency, if configured with no options on Mac OS X. 2006-05-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * src/base/ftmac.c (open_face_from_buffer): Deallocate stream when its content cannot be parsed as supported font. This fixes the second part of Savannah bug #16590. 2006-05-18 Werner Lemberg <wl@gnu.org> * src/truetype/ttgload.c (TT_Load_Composite_Glyph) [TT_CONFIG_OPTION_BYTECODE_INTERPRETER]: Make it compilable again. 2006-05-17 David Turner <david@freetype.org> This is a major patch used to drastically improve the performance of loading glyphs. This both speeds up loading the glyph vectors themselves and the auto-fitter module. We now use inline assembler code with GCC to implement `FT_MulFix', which is probably the most important function related to the engine's performance. The resulting speed-up is about 25%. * include/freetype/internal/tttypes.h (TT_LoaderRec): Add fields `cursor' and `limit'. * src/autofit/afangles.c (af_corner_is_flat, af_corner_orientation): New functions. (AF_ATAN_BITS, af_arctan, af_angle_atan): Comment out.

(FT_Stream_OpenGzip): Use it to handle small files directly in memory. * src/psaux/psconv.c (PS_Conv_ASCIIHexDecode, PS_Conv_EexecDecode): Improve performance. * src/truetype/ttgload.c (TT_Access_Glyph_Frame): Set `cursor' and `limit'. (TT_Load_Glyph_Header, TT_Load_Simple_Glyph, TT_Load_Composite_Glyph): Updated. Add threshold to protect against exceedingly large values of number of contours. Speed up by reducing the number of loops. * src/type1/t1gload.c (T1_Load_Glyph): Don't apply unit matrix. * src/cache/ftccmap.c (FTC_CMapCache_Lookup): Change the threshold used to detect rogue clients from 4 to 16. This is to prevent some segmentation faults with fonts like `KozMinProVI-Regular.otf' which comes from the Japanese Adobe Reader Asian Font pack. 2007-05-17 Werner Lemberg <wl@gnu.org> * src/cff/cffload.c (cff_font_done): Deallocate subfont array. This fixes the first part of Savannah bug #16590. 2006-05-16 Werner Lemberg <wl@gnu.org> * docs/PROBLEMS: Updated icl issues. ---------------------------------------------------------------------------- Copyright (C) 2006-2022 by David Turner, Robert Wilhelm, and Werner Lemberg.

2013-05-08 Werner Lemberg <wl@gnu.org> * Version 2.4.12 released. ========================== Tag sources with `VER-2-4-12'. * docs/VERSION.DLL: Update documentation and bump version number to 2.4.12. * README, Jamfile (RefDoc), builds/win32/vc2005/freetype.vcproj, builds/win32/vc2005/index.html, builds/win32/vc2008/freetype.vcproj, builds/win32/vc2008/index.html, builds/win32/vc2010/freetype.vcxproj, builds/win32/vc2010/index.html, builds/win32/visualc/freetype.dsp, builds/win32/visualc/freetype.vcproj, builds/win32/visualc/index.html, builds/win32/visualce/freetype.dsp, builds/win32/visualce/freetype.vcproj, builds/win32/visualce/index.html, builds/wince/vc2005-ce/freetype.vcproj, builds/wince/vc2005-ce/index.html, builds/wince/vc2008-ce/freetype.vcproj, builds/wince/vc2008-ce/index.html: s/2.4.11/2.4.12/, s/2411/2412/. * include/freetype/freetype.h (FREETYPE_PATCH): Set to 12. * builds/unix/configure.raw (version_info): Set to 16:1:10. 2013-05-08 Werner Lemberg <wl@gnu.org> * docs/CHANGES: Updated. 2013-05-08 Werner Lemberg <wl@gnu.org> * src/autofit/aflatin.c (af_latin_metrics_scale_dim): Typo. 2013-05-05 Werner Lemberg <wl@gnu.org> Synchronize `ftconfig.h'. * builds/unix/ftconfig.in: Updated. 2013-05-05 Werner Lemberg <wl@gnu.org> Fix compilation with C++. * src/base/md5.c (body): Use proper cast. 2013-05-05 Werner Lemberg <wl@gnu.org> Fix 64bit compilation issues. * include/freetype/config/ftconfig.h [FT_LONG64]: Typedef `FT_Int64' here. * src/base/ftcalc.c: Remove typedef of `FT_Int64'. (FT_DivFix): Fix cast. * src/base/fttrigon.c: Remove typedef of `FT_Int64'. 2013-05-05 Werner Lemberg <wl@gnu.org> [raster] Fix clang issues. Fix suggested by <octoploid@yandex.com>. * src/raster/ftraster.c (ULong): New typedef. (SCALED): Add proper cast. 2013-05-04 Werner Lemberg <wl@gnu.org> Fix clang fixes. * src/base/fttrigon.c (ft_trig_prenorm, FT_Vector_Rotate): Use correct types. * src/cff/cf2intrp.c (cf2_interpT2CharString) <default>: Force unsigned for computations. * src/cff/cffgload.c (cff_decoder_parse_charstrings): Ditto. * src/cff/cffparse.c (cff_parse_integer): Ditto. * src/psaux/t1decode.c (t1_decoder_parse_charstrings): Ditto. 2013-05-04 Werner Lemberg <wl@gnu.org> [cff] Make Adobe CFF engine work correctly on 64bit hosts. Reported by numerous people on the `freetype-devel' list. Without this fix, glyphs aren't properly aligned on a common baseline. On 64bit systems, `FT_Pos' expands to `long int', having a width of 64bit. `CF2_Fixed' expands to `int' which is normally 32bit wide on 64bit hosts also. Wrong casts filled up the blues arrays with incorrect values. Note that all blues values are accessed with the `cf2_blueToFixed' macro which handles the 64bit to 32bit conversion. * src/cff/cf2ft.h (cf2_getBlueValues, cf2_getOtherBlues, cf2_getFamilyBlues, cf2_getFamilyOtherBlues): Use `FT_Pos' for `data', not `CF2_Fixed'. * src/cff/cf2ft.c (cf2_getBlueValues, cf2_getOtherBlues, cf2_getFamilyBlues, cf2_getFamilyOtherBlues): Updated. * src/cff/cf2blues.c (cf2_blues_init): Updated. 2013-05-04 Werner Lemberg <wl@gnu.org> More fixes for clang's `sanitize' feature. * src/base/ftcalc.c (FT_DivFix): Use unsigned values for computations which use the left shift operator and convert to signed as the last step. * src/base/fttrigon.c (ft_trig_prenorm, FT_Vector_Rotate, FT_Vector_Length, FT_Vector_Polarize): Ditto. * src/cff/cffgload.c (cff_decoder_parse_charstrings): Simplify. * src/cff/cffload.c (cff_subfont_load): Fix constant. * src/cff/cffparse.c (cff_parse_integer, cff_parse_real, do_fixed, cff_parse_fixed_dynamic): Use unsigned values for computations which use the left shift operator and convert to signed as the last step. * src/cid/cidload.c (cid_get_offset): Ditto. * src/psaux/psconv.c (PS_Conv_ToFixed): Ditto. * src/psaux/t1decode.c (t1_decoder_parse_charstrings): Ditto. * src/truetype/ttinterp.c (TT_MulFix14, TT_DotFix14): Ditto. 2013-05-04 Werner Lemberg <wl@gnu.org> Fix errors reported by clang's `sanitize' feature. * include/freetype/internal/ftstream.h: Simplify and fix integer extraction macros. (FT_INT8_, FT_BYTE_I16, FT_BYTE_I32, FT_INT8_I16, FT_INT8_I32, FT_INT8_I32, FT_INT8_U32): Removed. (FT_PEEK_SHORT, FT_PEEK_LONG, FT_PEEK_OFF3, FT_PEEK_SHORT_LE, FT_PEEK_LONG_LE, FT_PEEK_OFF3_LE): Use unsigned values for computations and convert to signed as the last step. * src/cff/cf2fixed.h (cf2_intToFixed, cf2_fixedToInt, cf2_fracToFixed): Avoid shifts of negative values. (cf2_intToFrac, cf2_fixedToFrac, cf2_fixedTo26Dot6): Removed, unused. * src/cff/cf2intrp.c (cf2_interpT2CharString) <cf2_cmdEXTENDEDNMBR, default>: Use unsigned values for computations and convert to signed as the last step. Use proper types in tracing messages. * src/cff/cffgload.c (cff_decoder_parse_charstrings): Use unsigned values for computation of operands and convert to signed as the last step. Use proper type in tracing message. 2013-05-03 Werner Lemberg <wl@gnu.org> * src/cff/cf2blues.c: Remove dead code. 2013-05-02 Chris Liddell <chris.liddell@artifex.com> * src/cff/cffgload.c: Include FT_CFF_DRIVER_H. 2013-04-27 Werner Lemberg <wl@gnu.org> * docs/CHANGES: Updated. * README: Improved. 2013-04-13 Werner Lemberg <wl@gnu.org> [cff] Add a new Type 2 interpreter and hinter. This work, written by Dave Arnold <darnold@adobe.com> and fully integrated into FreeType by me, is a donation by Adobe in collaboration with Google. It is vastly superior to the old CFF engine, and it will replace it soon. Right now, it is still off by default, and you have to explicitly select it using the new `hinting-engine' property of the cff driver. For convenience, (most of) the new files are committed separately. * include/freetype/config/ftheader.h (FT_CFF_DRIVER_H): New macro. * include/freetype/ftcffdrv.h: New file to access CFF driver properties. * include/freetype/fterrdef.h (FT_Err_Glyph_Too_Big): New error code. * include/freetype/internal/fttrace.h: Add `cf2blues', `cf2hints', and `cf2interp'. * src/cff/cffgload.h (CFF_SubFont): New member `current_subfont'. * src/cff/cffobjs.h (CFF_DriverRec): New members `hinting_engine' and `no_stem_darkening'. * src/cff/cfftypes.h (CFF_FontRec): New member `cf2_instance'. * src/cff/cff.c: Include new files. * src/cff/cffdrivr.c (cff_property_set, cff_property_get): Handle `hinting-engine' and `no-stem-darkening' properties (only the Adobe engine listens to them). * src/cff/cffgload.c: Include `cf2ft.h'. (cff_decoder_prepare): Initialize `current_subfont'. (cff_build_add_point): Handle Adobe engine which uses 16.16 coordinates. (cff_slot_load): Handle FT_LOAD_NO_SCALE and FT_LOAD_NO_HINTING separately. Choose rendering engine based on `hinting_engine' property. * src/cff/cffload.c (cff_font_done): Call finalizer of the Adobe engine. * src/cff/cffobjs.c: Include FT_CFF_DRIVER_H. (cff_driver_init): Set default property values. * src/cff/rules.mk (CFF_DRV_SRC, CFF_DRV_H): Add new files. * src/cff/cf2*.*: New files, containing the Adobe engine. 2013-04-12 Werner Lemberg <wl@gnu.org> [cff] Minor code administration issues. * src/cff/cffgload.c (check_points): Rename to... (cff_check_points): ...this and make it FT_LOCAL. (cff_builder_add_point, cff_builder_add_point1, cff_builder_start_point, cff_builder_close_contour, cff_lookup_glyph_by_stdcharcode, cff_get_glyph_data, cff_free_glyph_data): Make them FT_LOCAL. * src/cff/cffgload.h: Updated. 2013-04-12 Werner Lemberg <wl@gnu.org> Add output bitmap checksums. Use `FT2_DEBUG=bitmap:3' for tracing. * src/base/md5.c, src/base/md5.h: New files, taken from https://openwall.info/wiki/people/solar/software/public-domain-source-code/md5 * include/freetype/internal/fttrace.h: Add `bitmap'. * src/base/ftobjs.c [FT_DEBUG_LEVEL_TRACE]: Include `md5.c' (FT_Render_Glyph_Internal) [FT_DEBUG_LEVEL_TRACE]: For tracing, convert resulting bitmap to a uniform format and compute a checksum. Use `bitmap' category for the tracing message. * src/base/rules.mk (BASE_H): Updated. * docs/LICENSE.TXT: Updated. 2013-04-12 Werner Lemberg <wl@gnu.org> [cff] Add framework for CFF properties. * include/freetype/internal/ftserv.h (FT_DEFINE_SERVICEDESCREC7): New macro. * src/cff/cffdrivr.c: Include FT_SERVICE_PROPERTIES_H. (cff_property_set, cff_property_get): New functions, still empty. Define `cff_service_properties' service. Update `cff_services'. * src/cff/cffpic.h: Include FT_SERVICE_PROPERTIES_H. (CFF_SERVICE_PROPERTIES_GET): New macro. (CffModulePIC): Add `cff_service_properties'. 2013-04-03 Werner Lemberg <wl@gnu.org> [bdf] Fix Savannah bug #38589. * src/bdf/bdflib.c (_bdf_readstream): Thinko. 2013-03-31 Werner Lemberg <wl@gnu.org> * configure: Use egrep, not grep. Problem reported Mojca Miklavec <mojca.miklavec.lists@gmail.com>. 2013-03-29 Werner Lemberg <wl@gnu.org> * include/freetype/ftlcdfil.h: Add description of color filtering. Based on a contribution from Antti S. Lankila <alankila@bel.fi> (Savannah bug #38607). 2013-03-23 Werner Lemberg <wl@gnu.org> [autofit] Minor. * src/autofit/afmodule.c (af_property_set): Typo. (af_autofitter_init, af_autofitter_done): Use cast. 2013-03-21 Werner Lemberg <wl@gnu.org> * configure: Automatically test for `gmake' also. Suggested by Mojca Miklavec <mojca.miklavec.lists@gmail.com>. 2013-03-21 Peter Breitenlohner <peb@mppmu.mpg.de> Respect CONFIG_SHELL from the environment. Some large packages using FreeType have to use a broken (deficient) /bin/sh. The configure scripts (as generated by Autoconf) are clever enough to find a better shell and put that one into the environment variable CONFIG_SHELL. If that environment variable is already set the script skips the test and assumes to be already running under a good shell. * builds/unix/detect.mk: Honour CONFIG_SHELL. * builds/unix/unix-def.in (SHELL): Define. 2013-03-21 Werner Lemberg <wl@gnu.org> Fix Savannah patch #7971. * configure: Handle MAKE environment variable also. 2013-03-17 Werner Lemberg <wl@gnu.org> Fix Savannah bug #38538. * builds/amiga/src/base/ftdebug.c, builds/win32/ftdebug.c, builds/wince/ftdebug.c (FT_Throw): Add function. 2013-03-17 Werner Lemberg <wl@gnu.org> [raster] Remove dead code. * src/raster/rastpic.c (ft_raster1_renderer_class_pic_init) src/smooth/ftspic.c (ft_smooth_renderer_class_pic_init): Do it. 2013-03-17 Werner Lemberg <wl@gnu.org> * src/pshinter/pshpic.h (GET_PIC): Use correct container. 2013-03-15 Werner Lemberg <wl@gnu.org> * include/freetype/ftmoderr.h: Fix commit from 2013-03-11. The previous version was not backward compatible. Reported by Behdad. 2013-03-14 Werner Lemberg <wl@gnu.org> */*: Use FT_ERR_EQ, FT_ERR_NEQ, and FT_ERR where appropriate. FT_Err_XXX and friends are no longer directly used in the source code. 2013-03-14 Werner Lemberg <wl@gnu.org> New error management macros. * include/freetype/fterrors.h (FT_ERR_XCAT, FT_ERR_CAT): Move to... * include/freetype/fttypes.h: ... this file. (FT_ERR, FT_ERR_EQ, FT_ERR_NEQ, FT_MODERR_EQ, FT_MODERR_NEQ): New macros. * include/freetype/freetype.h: Updated. 2013-03-14 Werner Lemberg <wl@gnu.org> */*: Use FT_Err_Ok only. This is a purely mechanical conversion. 2013-03-14 Werner Lemberg <wl@gnu.org> */*: Use `FT_THROW'. This is essentially a mechanical conversion, adding inclusion of `FT_INTERNAL_DEBUG_H' where necessary, and providing the macros for stand-alone compiling modes of the rasterizer modules. To convert the remaining occurrences of FT_Err_XXX and friends it is necessary to rewrite the code. Note, however, that it doesn't harm if some cases are not handled since FT_THROW is a no-op. 2013-03-13 Werner Lemberg <wl@gnu.org> Introduce `FT_THROW' macro. The idea is to replace code like return FT_Err_Foo_Bar; or return CFF_Err_Foo_Bar; with return FT_THROW( Foo_Bar ); The FT_THROW macro has two functions: . It hides the module specific prefix. . In debug mode, it calls the empty function `FT_Throw' which can be thus used to set a breakpoint. * include/freetype/internal/ftdebug.h (FT_THROW): New macro. (FT_Throw): New prototype. * src/base/ftdebug.c (FT_Throw): New function. 2013-03-12 Werner Lemberg <wl@gnu.org> Remove `FT_KEEP_ERR_PREFIX'. The idea is to always have FT_ERR_PREFIX available internally. * include/freetype/fterrors.h: Use FT2_BUILD_LIBRARY to guard undefinition of FT_ERR_PREFIX * src/gxvalid/gxverror.h, src/otvalid/otverror.h, src/sfnt/sferrors.h: Updated. 2013-03-11 Werner Lemberg <wl@gnu.org> [gxvalid] Fix module error. * src/gxvalid/gxverror.h (FT_ERR_BASE): Define as FT_Mod_Err_GXvalid. * include/freetype/ftmoderr.h: Add module error for `GXvalid'. 2013-03-11 Werner Lemberg <wl@gnu.org> Always use module related error codes. * src/cff/cffobjs.c (cff_face_init), src/type1/t1objs.c (T1_Face_Init), src/type42/t42objs.c (T42_Face_Init): Use `FT_ERROR_BASE'. * src/type1/t1load.c (parse_encoding): Use T1_Err_Unknown_File_Format. 2013-03-08 Werner Lemberg <wl@gnu.org> [cff] Set `linear{Hori,Vert}Advance' for embedded bitmaps also. Problem reported by Khaled Hosny <khaledhosny@eglug.org>. * src/cff/cffgload.c (cff_slot_load): Implement it. 2013-02-23 Alexei Podtelezhnikov <apodtele@gmail.com> [base] Fix commit ab02d9e8. * src/base/ftbbox.c (BBox_Cubic_Check): Change scaling to msb of 22. 2013-02-19 Alexei Podtelezhnikov <apodtele@gmail.com> [base] New bisecting BBox_Cubic_Check (disabled). * src/base/ftbbox.c (BBox_Cubic_Check): New bisecting algorithm for extremum search built around simple condition that defines which half contains the extremum. 2013-02-18 Alexei Podtelezhnikov <apodtele@gmail.com> [tools] Update BBox testing tool. * src/tools/test_bbox.c: Add another cubic outline with exact BBox. (REPEAT): Increase the number of benchmarking cycles. (profile_outline): Tweak output formatting. 2013-02-02 Werner Lemberg <wl@gnu.org> Fix Savannah bug #38235. * builds/unix/configure.raw: Don't generate `freetype-config' and `freetype.pc'. * builds/unix/unix-def.in (FT2_EXTRA_LIBS, LIBBZ2, LIBZ, build_libtool_libs, ft_version): New variables to be substituted. (freetype-config, freetype.pc): New rules to generate those files. * builds/unix/freetype-config.in: Remove code for handling `rpath'. The use of $rpath has been accidentally removed in a patch from 2009-12-22, and apparently noone has missed it since. Use `%' instead of `@' as a variable substitution marker. Use quotes. * builds/unix/freetype.in: Use `%' instead of `@' as a variable substitution marker. Use quotes. 2013-02-07 Werner Lemberg <wl@gnu.org> * src/truetype/ttobjs.c (tt_size_run_prep): Reset more GS variables. BTW, Greg agrees that the OpenType specification is missing the list of GS variables which will always be reset to the default values after the `prep' table has been executed. 2013-02-06 Werner Lemberg <wl@gnu.org> * src/truetype/ttobjs.c (tt_size_run_prep): Reset reference points. Up to now, we simply took a snapshot of the Graphics State after the `prep' table has been executed, and right before a glyph's bytecode was run it got reloaded. However, as Greg Hitchcock has told us in private communication, reference points get reset to zero in the MS rasterizer and we follow in due course. While reasonable, this is undocumented behaviour. Most notably, this fixes the rendering of Arial's `x' glyph in subpixel hinting mode. 2013-02-05 Werner Lemberg <wl@gnu.org> [truetype] A better fix for Savannah bug #38211. * src/truetype/ttinterp.c (Ins_IP): Implement identical behaviour to MS rasterizer if rp1 == rp2 (confirmed by Greg Hitchcock). 2013-02-01 Alexei Podtelezhnikov <apodtele@gmail.com> [pcf] Streamline parsing of PCF encoding table. * src/pcf/pcfread.c (pcf_get_encodings): Use simpler double for-loop.

This patches fixes many issues with the ttsubpix implementation. 1. Data tables are defined, instead of declared, in the header, and thus copied into each source file that includes it. 2. These tables were defined as global, mutable, visible variables, and thus costing private RAM to every process that loads the library (> 50 KB / process, this is huge!). Additionally, this also made the library export the symbols completely needlessly. 3. Missing `sph_' and `SPH_' prefixes to some of the definitions. Note that this doesn't try to fix the incredibly inefficient storage format for the data tables used by the code. This one will require another pass in the future. * src/truetype/ttinterp.h (MAX_NAME_SIZE, MAX_CLASS_MEMBERS): Renamed to... (SPH_MAX_NAME_SIZE, SPH_MAX_CLASS_MEMBERS): This. Update all users.

Unit vector components are stored as 2.14 fixed-point numbers. In order to calculate all 14 bits accurately, a short vector to be normalized has to be upscaled to at least 14 bits before its length is calculated. This has been safe since accurate CORDIC algorithms were adopted. * src/truetype/ttinterp.c (Normalize): Scale short vectors by 0x4000. 2013-01-12 Alexei Podtelezhnikov <apodtele@gmail.com> [truetype] Kill very old vector normalization hacks. Back in the days, vector length calculations were not very accurate and the vector normalization function, Normalize, had to meticulously correct the errors for long vectors [commit b7ef2b096867].

FreeType used to rely on a 24-step iteration CORDIC algorithm to calculate trigonometric functions and rotate vectors. It turns out that once the vector is in the right half-plane, the initial rotation by 63 degrees is not necessary. The algorithm is perfectly capable to converge to any angle starting from the second 45 degree rotation.

The dot product between freeVector and projVector or cosine of the angle between these FT_F2Dot14 unit vectors used to be scaled up by 4 and routinely occupied 32 bits in an FT_Long field F_dot_P. This patch scales the value down by 2^14 instead, which simplifies its use throughout the bytecode interpreter. This does not lead to the loss of precision because the lower bits are unreliable anyway. Consider two unit vectors (1,0) and (.6,.8) for which the true value of F_dot_P is .6 * 0x40000000 = 0x26666666. These vectors are stored as (0x4000,0) and (0x2666,0x3333) after rounding and F_dot_P is assigned 0x26660000. The lower bits were already lost while rounding the unit vector components. Besides code simplification, this change can lead to better performance when FT_MulDiv with the scaled-down F_dot_P is less likely to use the costly 64-bit path. We are not changing the type of F_dot_P to FT_F2Dot14 at this point. * src/truetype/ttinterp.c (Compute_Funcs): Scale F_dot_P down by 14 bits and modify its use accordingly. (Direct_Move, Direct_Move_Orig, Compute_Point_Displacement): Modify the use of F_dot_P field. * src/truetype/ttobjs.c (tt_size_run_fpgm): Change arbitrary assignment of F_dot_P to its theoretical maximum in case we decide to scale back its type later. 2012-12-09 Johnson Y.

This is the large, famous `Infinality' patch to support ClearType bytecode which has been available from http://www.infinality.net/blog/ for some time, and which has been refined over the last years. While still experimental, it is now mature enough to be included directly into FreeType. Most of the code is based on the ClearType whitepaper written by Greg Hitchcock https://www.microsoft.com/typography/cleartype/truetypecleartype.aspx which gives a detailed overview of the necessary changes to the Microsoft rasterizer so that older fonts are supported. However, a lot of details are still missing, and this patches provides a framework to easily handle rendering issues down to the glyph level of certain fonts. Note that ClearType support is not completely implemented! In particular, full support for the options `compatible_widths', `symmetrical_smoothing, and `bgr' (via the GETINFO bytecode instruction) is missing. * src/truetype/ttsubpix.c: New file, providing code to handle `tweaks', this is, rules for certain glyphs in certain fonts (including wildcards) which need a special treatment. * src/truetype/ttsubpix.h: New file, holding the tweaking rules. * include/freetype/config/ftoption.h, src/devel/ftoption.h (TT_CONFIG_OPTION_SUBPIXEL_HINTING): New macro. * include/freetype/internal/ftobjs.h (FT_PIX_FLOOR_GRID, FT_PIX_ROUND_GRID, FT_PIX_CEIL_GRID): New macros. * src/truetype/truetype.c [TT_USE_BYTECODE_INTERPRETER]: Include `ttsubpix.c'. * src/truetype/ttgload.c: Include `ttsubpix.h'.

Update all callers using `IS_INCREMENTAL'. 2012-03-11 Werner Lemberg <wl@gnu.org> [autofit] Return correct linear advance width values. This was quite a subtle bug which accidentally showed up with glyph `afii10023' of arial.ttf (version 2.76). This glyph is a composite; the first component, `E', has an advance width of 1366 font units, while the advance width of the composite itself (which looks like uppercase `E' with dieresis) is 1367 font units. I think this is actually a bug in the font itself, because there is no reason that this glyph has not the same width as uppercase `E' without the dieresis. Anyway, it helped identify this problem. Using the TrueType hinter, the correct value (1367) of `afii10023' was returned, but the autohinter mysteriously returned 1366. Digging in the code showed that the autohinter recursively calls FT_Load_Glyph to load the glyph, adding the FT_LOAD_NO_SCALE load flag. However, the `linearHoriAdvance' field is still returned as a scaled value. To avoid scaling twice, the old code in autofit reset `linearHoriAdvance', using the `horiAdvance' field. This seemed to work since FT_LOAD_NO_SCALE was in use, but it failed actually, because `horiAdvance' is defined as the distance of the first subglyph's phantom points, which in turn are initialized using the advance width of the first subglyph. And as the given example shows, these widths can differ. * src/autofit/afloader.c (af_loader_load_g): Temporarily set FT_LOAD_LINEAR_DESIGN while calling FT_Load_Glyph to get unscaled values for the linear advance widths. 2012-03-10 Werner Lemberg <wl@gnu.org> [truetype] Fix SSW instruction. * src/truetype/ttinterp.c (DO_SSW): SSW *does* use font units.

The MS Windows rasterizer behaves the same, as confirmed by Greg Hitchcock. * src/truetype/ttinterp.h (TT_CallRec): Add `Cur_End' element. * src/truetype/ttobjs.h (TT_DefRecord): Add `end' element. * src/truetype/ttinterp.c (DO_JROT, DO_JMPR, DO_JROF): Check upper bound of jump address. (Ins_FDEF, Ins_CALL, Ins_LOOPCALL, Ins_UNKNOWN, TT_RunIns): Updated. 2012-02-11 Werner Lemberg <wl@gnu.org> We don't use `extensions'. * include/freetype/internal/ftobjs.h (FT_DriverRec): Remove `extensions' field. 2012-02-11 Werner Lemberg <wl@gnu.org> Clean up `generic' fields. * include/freetype/internal/ftobjs.h (FT_ModuleRec, FT_LibraryRec): Remove `generic' field since users can't access it. * src/base/ftobjs.c (FT_Done_GlyphSlot): Call `generic.finalizer' as advertised in the documentation of FT_Generic. (Destroy_Module, FT_Done_Library): Updated to changes in `ftobjs.h'. 2012-02-07 Werner Lemberg <wl@gnu.org> [autofit] Harmonize function arguments. * src/autofit/afloader.c, src/autofit/afloader.h: Use `FT_Int32' for `load_flags'. 2012-02-07 Werner Lemberg <wl@gnu.org> * src/cff/cffobjs.c (cff_face_init): Remove unnecessary casts. 2012-01-17 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> [gxvalid] Fix Savannah bug #35286. Patch submitted by anonymous reporter. * src/gxvalid/gxvcommn.c (gxv_XStateTable_subtable_setup): gxv_set_length_by_ulong_offset() must be called with 3, not 4, the number of the subtables in the state tables; classTable, stateArray, entryTable. 2012-01-17 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> [raccess] Modify for PIC build. Based on the patch provided by Erik Dahlstrom <ed@opera.com>, https://lists.gnu.org/archive/html/freetype-devel/2012-01/msg00010.html Also `raccess_guess_table[]' and `raccess_rule_by_darwin_vfs()' are renamed with `ft_' suffixes. * src/base/ftbase.h: `raccess_rule_by_darwin_vfs()' is renamed to `ft_raccess_rule_by_darwin_vfs()'. * src/base/ftobjs.c: Ditto. * src/base/ftrfork.c: Declarations of FT_RFork_Rule, raccess_guess_rec, are moved to... * include/freetype/internal/ftrfork.h: Here. * include/freetype/internal/ftrfork.h: FT_RFORK_RULE_ARRAY_{BEGIN,ENTRY,END} macros are defined to replace raccess_guess_table[] in both of PIC and non-PIC modes. * src/base/ftrfork.c: raccess_guess_table[] array is rewritten by FT_RFORK_RULE_ARRAY_{BEGIN,ENTRY,END}. * src/base/basepic.h (BasePIC): Add `ft_raccess_guess_table' storage. (FT_RACCESS_GUESS_TABLE_GET): New macro to retrieve the function pointer from `ft_raccess_guess_table' storage in `BasePIC' structure. * src/base/ftrfork.c (FT_Raccess_Guess): Rewritten with FT_RACCESS_GUESS_TABLE_GET. (raccess_get_rule_type_from_rule_index): Add `library' as the first argument to the function, to retrieve the storage of `ft_raccess_guess_table' from it. Also `raccess_guess_table' is replaced by FT_RACCESS_GUESS_TABLE_GET. (ft_raccess_rule_by_darwin_vfs): Ditto. 2012-01-16 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> Remove trailing spaces. 2012-01-16 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> Formatting PIC related sources. * src/autofit/afpic.c: Harmonize to FT2 coding conventions. * src/base/basepic.c: Ditto. * src/base/ftpic.c: Ditto. * src/cff/cffpic.c: Ditto. * src/pshinter/pshpic.c: Ditto. * src/psnames/pspic.c: Ditto. * src/raster/rastpic.c: Ditto. * src/sfnt/sfntpic.c: Ditto. * src/smooth/ftspic.c: Ditto. * src/truetype/ttpic.c: Ditto. 2012-01-16 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> [autofit] Fix the inclusion of `aflatin2.h' in PIC file. * src/autofit/afpic.c: Include `aflatin2.h' when FT_OPTION_AUTOFIT2 is defined, as afglobal.c does so. Unconditionally inclusion causes declared but unimplemented warning by GCC 4.6. 2012-01-16 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> [cff] Remove redundant declarations of cff_cmap_XXX_class_rec. * src/cff/cffpic.c: The declarations of FT_Init_Class_cff_cmap_encoding_class_rec() and FT_Init_Class_cff_cmap_unicode_class_rec() are removed. They can be obtained by the inclusion of cffcmap.h. cffcmap.h invokes FT_DECLARE_CMAP_CLASS() and it declares FT_Init_Class_cff_cmap_encoding_class_rec() etc in PIC mode. 2012-01-15 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> Fix redundant declaration warning in PIC mode. Originally FT_DEFINE_{DRIVER,MODULE,RENDERER}() macros were designed to declare xxx_pic_{free,init} by themselves. Because these macros are used at the end of the module interface (e.g. ttdriver.c) and the wrapper source to build a module as a single object (e.g. truetype.c) includes the PIC file (e.g. ttpic.c) before the module interface, these macros are expanded AFTER xxx_pic_{free,init} body when the modules are built as single object. The declaration after the implementation causes the redundant declaration warnings, so the declarations are moved to module PIC headers (e.g. ttpic.h). Separating to other header files are needed for multi build. * include/freetype/internal/ftdriver.h (FT_DEFINE_DRIVER): Remove class_##_pic_free and class_##_pic_init declarations. * include/freetype/internal/ftobjs.h (FT_DEFINE_RENDERER, FT_DEFINE_MODULE): Ditto. * src/base/basepic.h: Insert a comment and fix coding style. * src/autofit/afpic.h: Declare autofit_module_class_pic_{free, init}. * src/cff/cffpic.h: Declare cff_driver_class_pic_{free,init}. * src/pshinter/pshpic.h: Declare pshinter_module_class_pic_{free, init}. * src/psnames/pspic.h: Declare psnames_module_class_pic_{free, init}. * src/raster/rastpic.h: Declare ft_raster{1,5}_renderer_class_pic_{free,init} * src/sfnt/sfntpic.h: Declare sfnt_module_class_pic_{free,init}. * src/smooth/ftspic.h: Declare ft_smooth_{,lcd_,lcdv_}renderer_class_pic_{free,init}. * src/truetype/ttpic.h: Declare tt_driver_class_pic_{free,init}. 2012-01-15 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> Make pspic.c to include module error header to fix multi build. * src/psnames/pspic.c: Include `psnamerr.h'. 2012-01-14 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> [base] Fix a dereference of uninitialized variable in PIC mode. * src/base/ftglyph.c (FT_Glyph_To_Bitmap): `glyph' must be set before dereferring to obtain `library'. The initialization of `clazz', `glyph', `library' and NULL pointer check are reordered to minimize PIC conditionals. 2012-01-14 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> [base] Insert explicit cast for GCC 4.6 in PIC mode. * src/base/ftinit.c (FT_Add_Default_Modules): Under PIC configuration, FT_DEFAULT_MODULES_GET returns FT_Module_Class** pointer, GCC 4.6 warns that const FT_Module_Class* const* variable is warned as inappropriate to store it. To calm it, explicit cast is inserted. Also `library' is checked to prevent the NULL pointer dereference in FT_DEFAULT_MODULES_GET. 2012-01-13 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> Fix PIC build broken by d9145241fe378104ba4c12a42534549faacc92e6. Under PIC configuration, FT_{CFF,PSCMAPS,SFNT,TT}_SERVICES_GET take no arguments but derefer the variable named `library' internally. * src/cff/cffdrivr.c (cff_get_interface): Declare `library' and set it if non-NULL driver is passed. * src/truetype/ttdriver.c (tt_get_interface): Ditto. * src/sfnt/sfdriver.c (sfnt_get_interface): Declare `library' under PIC configuration, and set it if non-NULL module is given. * src/psnames/psmodule.c (psnames_get_interface): Ditto. 2012-01-13 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> Make PIC files include module error headers, to use the error codes with per-module prefix. * src/autofit/afpic.c: Include `aferrors.h'. * src/cff/cffpic.c: Include `cfferrs.h'. * src/pshinter/pshpic.c: Include `pshnterr.h'. * src/raster/rastpic.c: Include `rasterrs.h'. * src/sfnt/sfntpic.c: Include `sferrors.h'. * src/smooth/ftspic.c: Include `ftsmerrs.h'. * src/truetype/ttpic.c: Include `tterrors.h'. 2012-01-04 Tobias Ringström <tobias@ringis.se> [truetype] Fix IP instruction if x_ppem != y_ppem. * src/truetype/ttinterp.c (Ins_IP): Scale `orus' coordinates properly. 2012-01-02 Werner Lemberg <wl@gnu.org> Fix tracing message for `loca' table. * src/truetype/ttpload.c (tt_face_get_location): Don't emit a warning message if the last `loca' entry references an empty glyph. 2011-12-10 Werner Lemberg <wl@gnu.org> Add some variable initializations. Reported by Richard COOK <rscook@unicode.org>. * src/type1/t1driver.c (t1_ps_get_font_value): Initialize `val'. * src/smooth/ftgrays.c (gray_render_conic): Initialize `levels' earlier. 2011-12-08 Werner Lemberg <wl@gnu.org> Fix serious scaling bug in `FT_Get_Advances'. * src/base/ftadvanc.c (FT_Get_Advances): Advance values returned by `FT_Load_Glyph' must be simply multiplied by 1024. 2011-12-08 Werner Lemberg <wl@gnu.org> * src/bdf/bdflib.c (_bdf_parse_start): Drop redundant error tracing. 2011-12-02 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> [mac] Unify DARWIN_NO_CARBON with FT_MACINTOSH. Originally FT_MACINTOSH was a pure auto macro and DARWIN_NO_CARBON was a configurable macro to disable Carbon-dependent code. Because now configure script sets DARWIN_NO_CARBON by default and disables Darwin & Carbon-dependent codes, these macros can be unified. FT_MACINTOSH (undefined by default) is kept and DARWIN_NO_CARBON (defined by default) is removed, because DARWIN_NO_CARBON violates FT_XXX naming convention of public macros, and a macro configured by default is not portable for the building without configure (e.g. make devel). * builds/unix/configure.raw: Define FT_MACINTOSH if Carbon-based old Mac font support is requested and Carbon is available. * builds/unix/ftconfig.in: Undefine FT_MACINTOSH when the support for Mac OS X without Carbon (e.g. Mac OS X 10.4 for ppc64) is requested. * include/freetype/config/ftconfig.in: Ditto. * builds/vms/ftconfig.h: Ditto. * src/base/ftbase.h: Remove DARWIN_NO_CARBON. * src/base/ftbase.c: Ditto. * src/base/ftobjs.c: Ditto. * src/base/ftrfork.c: Ditto. * src/base/ftmac.c: Compile the body if FT_MACINTOSH is defined (same with TT_USE_BYTECODE_INTERPRETER in ttinterp.c). * builds/mac/ftmac.c: Ditto. * builds/mac/FreeType.m68k_cfm.make.txt: Define FT_MACINTOSH. * builds/mac/FreeType.m68k_far.make.txt: Ditto. * builds/mac/FreeType.ppc_classic.make.txt: Ditto. * builds/mac/FreeType.ppc_carbon.make.txt: Ditto. 2011-11-30 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> Fix Savannah bug #34728 (`make devel' on Mac OS X). * builds/toplevel.mk: Check `/dev/null' to identify the Unix- like systems without `init' nor `hurd' (e.g. Mac OS X >= 10.4). * builds/unix/detect.mk: Ditto. 2011-11-30 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> [apinames] Fix the overflow of signed integer hash. * src/tools/apinames.c (names_add): Change the type of `h' from int to unsigned int, to prevent undefined behaviour in the overflow of signed integers (overflow of unsigned int is defined to be wrap around). Found by clang test suggested by Sean McBride. 2011-11-30 Werner Lemberg <wl@gnu.org> [winfonts] Remove casts. * src/winfonts/winfnt.c (winfnt_driver_class): Remove all casts and update affected functions. (FNT_Size_Select): Fix number of arguments. 2011-11-30 Werner Lemberg <wl@gnu.org> [type42] Remove casts. * src/type42/t42drivr.c (t42_driver_class): Remove all casts and update affected functions. * src/type42/t42objs.c, src/type42/t42objs.h: Updated for t42 driver changes. 2011-11-30 Werner Lemberg <wl@gnu.org> [type1] Remove casts. * src/type1/t1driver.c (t1_driver_class): Remove all casts and update affected functions. * src/type1/t1gload.c, src/type1/t1gload.h, src/type1/t1objs.c: Updated for t1driver changes. src/type1/t1objs.h (T1_Driver): Remove unused typedef. Updated for t1driver changes. 2011-11-27 Werner Lemberg <wl@gnu.org> [bdf] Fix Savannah bug #34896. ENCODING now covers the whole Unicode range. Note, however, that this change is quite expensive since it increases the size of three arrays by almost 400kByte in total. The right fix is to replace the logic with something smarter. Additionally, there exist very old BDFs for three-byte CCCII encoding which exceeds the range of Unicode (another reason to have a smarter logic). * src/bdf/bdf.h (bdf_font_t): Increase size of `nmod' and `umod' arrays. * src/bdf/bdflib.c (bdf_parse_t): Increase size of `have' array. 2011-11-27 Werner Lemberg <wl@gnu.org> [bdf] Improve tracing. * src/bdf/bdflib.c (DBGMSG1, DBGMSG2): New macros. (_bdf_parse_glyphs): Use them. 2011-11-26 Werner Lemberg <wl@gnu.org> Improve tracing. * src/bdf/bdfdrivr.c (BDF_Face_Done), src/pcf/pcfdrivr.c (PCF_Face_Done): Remove tracing message. * src/bdf/bdfdrivr.c (BDF_Face_Init), src/cff/cffobjs.c (cff_face_init), src/cid/cidobjs.c (cid_face_init), src/pfr/pfrobjs.c (pfr_face_init), src/sfnt/sfobjs.c (sfnt_init_face), src/truetype/ttobjs.c (tt_face_init), src/type1/t1objs.c (T1_Face_Init), src/type42/t42objs.c (T42_Face_Init), src/winfonts/winfnt.c (FNT_Face_Init): Add `greeting' message. * src/sfnt/sfobjs.c (sfnt_open_font), src/type42/t42objs.c (T42_Open_Face): Improve tracing. 2011-11-26 Werner Lemberg <wl@gnu.org> [cid] Fix error code. * src/cid/cidparse.c (cid_parser_new): Do it. 2011-11-26 Werner Lemberg <wl@gnu.org> [cff] Fix error code. * src/cff/cffload.c (cff_font_load): Do it. 2011-11-26 Werner Lemberg <wl@gnu.org> Add new error code FT_Err_Missing_Module. Previously, FreeType misleadingly returned FT_Err_Unknown_File_Format if a module was missing (or a test was missing completely). * include/freetype/fterrdef.h (FT_Err_Missing_Module): Define. * src/cff/cffobjs.c (cff_face_init), src/cff/cffdrivr.c (cff_get_glyph_name), src/cid/cidobjs.c (cid_face_init), src/sfnt/sfobjs.c (sfnt_init_face), src/truetype/ttobjs.c (tt_face_init), src/type1/t1objs.c (T1_Face_Init), src/type42/t42objs.c (T42_Face_Init, T42_Driver_Init): Updated. * src/type1/t1afm.c (T1_Read_Metrics), src/type/t1objs.c (T1_Face_Init), src/type42/t42objs.c (T42_Face_Init): Remove now redundant test for `psaux'. 2011-11-25 Werner Lemberg <wl@gnu.org> [bdf] Add more error messages. * src/bdf/bdflib.c (_bdf_set_default_spacing, _bdf_add_property): Add line number argument. Update all callers. (ERRMSG5, ERRMSG6, ERRMSG7, ERRMSG8, ERRMSG9): New macros. (_bdf_readstream, _bdf_set_default_spacing, _bdf_add_property, _bdf_parse_glyphs, _bdf_parse_start): Add error messages. 2011-11-24 Werner Lemberg <wl@gnu.org> * include/freetype/fterrors.h: Remove dead code. 2011-11-15 Werner Lemberg <wl@gnu.org> * docs/releases: Updated. 2011-11-15 Werner Lemberg <wl@gnu.org> * Version 2.4.8 released. ========================= Tag sources with `VER-2-4-8'. * docs/CHANGES: Updated. * docs/VERSION.DLL: Update documentation and bump version number to 2.4.8. * README, Jamfile (RefDoc), builds/win32/vc2005/freetype.vcproj, builds/win32/vc2005/index.html, builds/win32/vc2008/freetype.vcproj, builds/win32/vc2008/index.html, builds/win32/vc2010/freetype.vcxproj, builds/win32/vc2010/index.html, builds/win32/visualc/freetype.dsp, builds/win32/visualc/freetype.vcproj, builds/win32/visualc/index.html, builds/win32/visualce/freetype.dsp, builds/win32/visualce/freetype.vcproj, builds/win32/visualce/index.html, builds/wince/vc2005-ce/freetype.vcproj, builds/wince/vc2005-ce/index.html, builds/wince/vc2008-ce/freetype.vcproj, builds/wince/vc2008-ce/index.html: s/2.4.7/2.4.8/, s/247/248/. * include/freetype/freetype.h (FREETYPE_PATCH): Set to 8. * builds/unix/configure.raw (version_info): Set to 14:0:8. 2011-11-13 Chris Liddell <chris.liddell@artifex.com> Add FT_Get_PS_Font_Value() API. This allows a Type 1 font face to be interrogated to retrieve most of the dictionary keys (keys not relevant to FreeType's Type 1 interpreter are not available). * include/freetype/internal/services/svpsinfo.h (PS_GetFontValueFunc): New typedef. (PSInfo): Add `ps_get_font_value'. (FT_DEFINE_SERVICE_PSINFOREC): Updated. * include/freetype/internal/t1types.h (T1_EncodingType): Moved to... * include/freetype/t1tables.h: Here. (PS_Dict_Keys): New enumeration. (FT_Get_PS_Font_Value): New declaration. * src/base/fttype1.c (FT_Get_PS_Font_Value): New function. * src/type1/t1driver.c (t1_ps_get_font_value): This new function does the real job. (t1_service_ps_info): Add it. * src/cff/cffdrivr.c (cff_service_ps_info), src/cid/cidriver.c (cid_service_ps_info), src/type42/t42drivr.c (t42_service_ps_info): Updated. 2011-11-08 Braden Thomas <bthomas@apple.com> [cid] Various loading fixes. * src/cid/cidload.c (cid_load_keyword) <default>, (parse_font_matrix, parse_expansion_factor): Correctly check number of dictionaries. (cid_read_subrs): Protect against invalid values of `num_subrs'. Assure that the elements of the `offsets' array are ascending. 2011-11-05 Werner Lemberg <wl@gnu.org> * README: We use copyright ranges also. According to https://www.gnu.org/prep/maintain/html_node/Copyright-Notices.html this should be mentioned explicitly. 2011-10-30 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> [raccess] Supplement for previous fix. * src/base/ftbase.h (raccess_rule_by_darwin_vfs): Do not declare it on native Mac OS X. * src/base/ftrfork.c (raccess_get_rule_type_from_rule_index): Hide raccess_get_rule_type_from_rule_index() on native Mac OS X too. 2011-10-30 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> [raccess] Hide raccess_rule_by_darwin_vfs() on native Mac OS X. * src/base/ftrfork.c (raccess_rule_by_darwin_vfs): Do not compile on native Mac OS X because it is not used. 2011-10-25 Werner Lemberg <wl@gnu.org> [truetype] Fix MD instruction for twilight zone. * src/truetype/ttinterp.c (Ins_MD): Without this fix, the MD instruction applied to original coordinates of twilight points always returns zero. 2011-10-18 Werner Lemberg <wl@gnu.org> * Version 2.4.7 released. ========================= Tag sources with `VER-2-4-7'. * docs/CHANGES: Updated. * docs/VERSION.DLL: Update documentation and bump version number to 2.4.7. * README, Jamfile (RefDoc), builds/win32/vc2005/freetype.vcproj, builds/win32/vc2005/index.html, builds/win32/vc2008/freetype.vcproj, builds/win32/vc2008/index.html, builds/win32/vc2010/freetype.vcxproj, builds/win32/vc2010/index.html, builds/win32/visualc/freetype.dsp, builds/win32/visualc/freetype.vcproj, builds/win32/visualc/index.html, builds/win32/visualce/freetype.dsp, builds/win32/visualce/freetype.vcproj, builds/win32/visualce/index.html, builds/wince/vc2005-ce/freetype.vcproj, builds/wince/vc2005-ce/index.html, builds/wince/vc2008-ce/freetype.vcproj, builds/wince/vc2008-ce/index.html: s/2.4.6/2.4.7/, s/246/247/. * include/freetype/freetype.h (FREETYPE_PATCH): Set to 7. * builds/unix/configure.raw (version_info): Set to 13:2:7. 2011-10-15 Kal Conley <kcconley@gmail.com> Fix handling of transformations if no renderer is present. * src/base/ftobjs.c (FT_Load_Glyph): Thinko. 2011-10-15 Kal Conley <kcconley@gmail.com> Fix conditions for autohinting. * src/base/ftobjs.c (FT_Load_Glyph): Handle FT_LOAD_IGNORE_TRANSFORM. 2011-10-07 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> [gxvalid] Fix a bug to detect too large offset in morx table. * src/gxvalid/gxvmorx2.c (gxv_morx_subtable_type2_ligActionIndex_validate): Fix a bug that too large positive offset cannot be detected. 2011-10-01 Braden Thomas <bthomas@apple.com> Handle some border cases. * include/freetype/config/ftstdlib.h (FT_USHORT_MAX): New macro. * src/base/ftbitmap.c (FT_Bitmap_Convert): Protect against invalid value of `target->rows'. * src/psaux/t1decode.c (t1_decoder_parse_charstrings): Add check for flex start. * src/raster/ftrend1.c (ft_raster1_render): Check `width' and `height'. * src/truetype/ttgxvar.c (TT_Vary_Get_Glyph_Deltas): Protect against invalid values in `localpoints' array. 2011-10-01 Werner Lemberg <wl@gnu.org> [psnames] Handle zapfdingbats. Problem reported by Nicolas Rougier <Nicolas.Rougier@inria.fr>. * src/tools/glnames.py (adobe_glyph_list): Add data from AGL's `zapfdingbats.txt' file. * src/psnames/pstables.h: Regenerated. 2011-09-27 Simon Bünzli <zeniko@gmail.com> [type1] Fix Savannah bug #34189. * src/type1/t1load.c (T1_Open_Face): Initialize `face->len_buildchar'. 2011-09-26 Werner Lemberg <wl@gnu.org> [cff] Dump SIDs while tracing. * src/cff/cffobjs.c (cff_face_init): Do it. * src/cff/cffparse.c (cff_parser_run) [FT_DEBUG_LEVEL_TRACE] <cff_kind_string>: Identify as SID. 2011-09-17 Werner Lemberg <wl@gnu.org> Remove unused FT_ALIGNMENT macro. * builds/unix/ftconfig.in, builds/vms/ftconfig.h, include/freetype/config/ftconfig.h: Do it. 2011-09-17 Alexei Podtelezhnikov <apodtele@gmail.com> [smooth] Slightly optimize conic and cubic flatteners. * src/smooth/ftgrays.c (gray_render_conic, gray_render_cubic): Move out some code from the main loop to speed it up. 2011-09-11 Tomas Hoger <thoger@redhat.com> Slightly improve LZW_CLEAR handling. * src/lzw/ftzopen.c (ft_lzwstate_io) <FT_LZW_PHASE_CODE>: Ensure that subsequent (modulo garbage byte(s)) LZW_CLEAR codes are handled as clear codes. This also re-sets old_code and old_char to predictable values, which is a little better than using `random' ones if the code following LZW_CLEAR is invalid. 2011-09-11 Tomas Hoger <thoger@redhat.com> Add explicit LZW decompression stack size limit. Stack larger than 1<<LZW_MAX_BITS is never needed if prefix table is constructed correctly. It's even less than that, see e.g. libarchive code comment for a better size upper bound: http://code.google.com/p/libarchive/source/browse/trunk/libarchive/archive_read_support_filter_compress.c?r=3635#121 This patch adds explicit stack size limit, enforced when stack is realloced. An alternative is to ensure that code < state->prefix[code - 256] when traversing prefix table. Such check is less efficient and should not be required if prefix table is constructed correctly in the first place. * src/lzw/ftzopen.c (ft_lzwstate_stack_grow): Implement it. 2011-09-11 Tomas Hoger <thoger@redhat.com> Protect against loops in the prefix table.

The main problems ----------------- o If FT_STROKER_LINEJOIN_BEVEL was specified, unlimited miter joins (not bevel joins) were generated. Indeed, the meanings of `miter' and `bevel' were incorrectly reversed (consistently) in both the code and comments. o The way bevel joins were constructed (whether specified explicitly, or created as a result of exceeding the miter limit) did not match what is required for stroked text in PostScript or PDF. The main fixes -------------- o The behaviour of FT_STROKER_LINEJOIN_BEVEL has been corrected. o A new line join style, FT_STROKER_LINEJOIN_MITER_FIXED, has been introduced to support PostScript and PDF miter joins. o FT_STROKER_LINEJOIN_MITER_VARIABLE has been introduced as an alias for FT_STROKER_LINEJOIN_MITER. Additionally, a variety of stroking errors have been fixed. These would cause various artifacts (including points `at infinity'), especially when stroking poor quality fonts. See https://lists.gnu.org/archive/html/freetype-devel/2011-07/msg00001.html for example documents. The FreeType stroker now produces results very similar to that produced by GhostScript and Distiller for these fonts. Other problems -------------- The following problems have been resolved: o Inside corners could be generated incorrectly. Intersecting the inside corner could cause a missing triangular area and other effects. The intersection point can only be used if the join is between two lines and both lines are long enough. The `optimization' condition in `ft_stroker_inside' has been corrected; this requires the line length to be passed into various functions and stored in `FT_StrokerRec'. o Incorrect cubic curves could be generated. The angle calculations in `FT_Stroker_CubicTo' have been corrected to handle the case of the curve crossing the +/-PI direction. o If the border radius was greater than the radius of curvature of a curve, then the negative sector would end up outside (not inside) the border. This situation is now recognized and the negative sector is circumnavigated in the opposite direction. (If round line joins are being used, this code is disabled because the line join will always cover the negative sector.) o When a curve is split, the arcs may not join smoothly (especially if the curve turns sharply back on itself). Changes in direction between adjacent arcs were not handled. A round corner is now added if the deviation from one arc to the next is greater than a suitable threshold. o The current direction wasn't retained if a the outline contained a zero length lineto or a curve that was determined to be `basically a point'. This could cause a spurious join to be added. o Cubics with close control points could be mishandled. All eight cases are now distinguished correctly. Other improvements ------------------ o Borders for cubic curves could be too `flat'. FT_SMALL_CUBIC_THRESHOLD has been reduced a little to prevent this. o The handling and use of movable points has been simplified a little. o Various values are now computed only if the results are actually needed. o The directions of the outer and inner borders have been swapped, as recommended by Graham Asher. * src/base/ftstroke.c: Revised. * include/freetype/ftstroke.h: Updated. 2011-06-30 İsmail Dönmez <ismail@namtrac.org> * builds/toplevel.mk: We use git, not CVS, thus skip `.gitignore'. 2011-06-29 Werner Lemberg <wl@gnu.org> [bdf] Fix Savannah bug #33663. * src/bdf/bdflib.c (_bdf_parse_glyphs): Handle negative values for ENCODING correctly. * docs/CHANGES: Document it. 2011-06-24 Werner Lemberg <wl@gnu.org> * Version 2.4.5 released. ========================= Tag sources with `VER-2-4-5'. * docs/CHANGES: Updated. * docs/VERSION.DLL: Update documentation and bump version number to 2.4.5 * README, Jamfile (RefDoc), builds/win32/vc2005/freetype.vcproj, builds/win32/vc2005/index.html, builds/win32/vc2008/freetype.vcproj, builds/win32/vc2008/index.html, builds/win32/vc2010/freetype.vcxproj, builds/win32/vc2010/index.html, builds/win32/visualc/freetype.dsp, builds/win32/visualc/freetype.vcproj, builds/win32/visualc/index.html, builds/win32/visualce/freetype.dsp, builds/win32/visualce/freetype.vcproj, builds/win32/visualce/index.html, builds/wince/vc2005-ce/freetype.vcproj, builds/wince/vc2005-ce/index.html, builds/wince/vc2008-ce/freetype.vcproj, builds/wince/vc2008-ce/index.html: s/2.4.4/2.4.5/, s/244/245/. * include/freetype/freetype.h (FREETYPE_PATCH): Set to 5. * builds/unix/configure.raw (version_info): Set to 13:0:7. 2011-06-20 Werner Lemberg <wl@gnu.org> * src/autofit/aflatin.c (af_latin_metrics_scale_dim): Fix change from 2011-05-04. 2011-06-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> [gxvalid] make the `prop' validation tracing verbose. * src/gxvalid/gxvprop.c: Add tracing messages for errors. 2011-06-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> [autogen.sh] Reflect environment variable LIBTOOLIZE. 2011-06-18 Werner Lemberg <wl@gnu.org> Update license documentation. * docs/GPL.TXT: Renamed to... * docs/GPLv2.TXT: This. * docs/LICENSE.TXT: Updated. 2011-06-14 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> Fix g++4.6 compiler warnings in module drivers.

(af_cjk_hint_edges): Add code to align the edge stems to blue zones. * src/autofit/afindic.c (af_indic_metrics_init): Take AF_CJKMetric instead of AF_LatinMetric, and initialize as af_cjk_metrics_init. However bluezones are not initialized. (af_indic_metrics_scale): Take AF_CJKMetric instead of AF_LatinMetric. (af_indic_hints_init): Ditto. (af_indic_hints_apply): Ditto. * docs/CHANGES: Note about CJK bluezone support. 2011-05-06 Werner Lemberg <wl@gnu.org> [autofit] Remove unused struct member. * src/autofit/aflatin.h (AF_LatinAxis): Remove `control_overshoot'. 2011-05-04 Werner Lemberg <wl@gnu.org> * src/autofit/aflatin.c (af_latin_metrics_scale_dim): Simplify. 2011-05-01 Just Fill Bugs <mozbugbox@yahoo.com.au> Werner Lemberg <wl@gnu.org> [autofit] Add more debugging functions. * src/autofit/afhints.c (af_glyph_hints_get_num_segments, af_glyph_hints_get_segment_offset): New functions. 2011-05-01 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> Add new option `--disable-mmap' to configure script. * builds/unix/configure.raw: New option `--disable-mmap' is added. It is for the developers to simulate the systems without mmap() (like 4.3BSD, minix etc) on POSIX systems. 2011-04-30 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> [truetype] Always recalculate the sfnt table checksum. * src/truetype/ttobjs.c (tt_get_sfnt_checksum): Recalculate the sfnt table checksum even if non-zero value is written in the TrueType font header. Some bad PDF generators write wrong values. For details see examples and benchmark tests of the latency by recalculation: https://lists.gnu.org/archive/html/freetype-devel/2011-04/msg00091.html https://lists.gnu.org/archive/html/freetype-devel/2011-04/msg00096.html 2011-04-30 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> [truetype] Register a set of tricky fonts, NEC FA family. * src/truetype/ttobjs.c (tt_check_trickyness_sfnt_ids): Add 8 checksum sets for NEC FA family. For the tricky fonts without some tables (e.g. NEC FA fonts lack cvt table), extra check is added to assure that a zero-length table in the registry is not included in the font. 2011-04-29 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> [truetype] Fix a bug in the sfnt table checksum getter. * src/truetype/ttobjs.c (tt_get_sfnt_checksum): Check the return value of face->goto_table() correctly. 2011-04-28 Werner Lemberg <wl@gnu.org> [autofit] Improve tracing messages. * src/autofit/aflatin.c (af_latin_metrics_init_blues, af_latin_align_linked_edge, af_latin_hint_edges): Do it. 2011-04-25 Kan-Ru Chen <kanru@kanru.info> [truetype] Always check the checksum to identify tricky fonts. Because some PDF generators mangle the family name badly, the trickyness check by the checksum should be invoked always. For sample PDF, see https://lists.gnu.org/archive/html/freetype-devel/2011-04/msg00073.html * src/truetype/ttobjs.c (tt_check_trickyness): Even when tt_check_trickyness_family() finds no trickyness, tt_check_trickyness_sfnt_ids() is invoked. 2011-04-22 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> [autofit] Add more Indic scripts with hanging baseline. * src/autofit/afindic.c (af_indic_uniranges): Tibetan, Limbu, Sundanese, Meetei Mayek, Syloti Nagri and Sharada scripts are added. 2011-04-21 Behdad Esfahbod <behdad@behdad.org> Always ignore global advance. This makes FT_LOAD_IGNORE_GLOBAL_ADVANCE_WIDTH redundant, deprecated, and ignored. The new behavior is what every major user of FreeType has been requesting. Global advance is broken in many CJK fonts. Just ignoring it by default makes most sense. * src/truetype/ttdriver.c (tt_get_advances), src/truetype/ttgload.c (TT_Get_HMetrics, TT_Get_VMetrics, tt_get_metrics, compute_glyph_metrics, TT_Load_Glyph), src/truetype/ttgload.h: Implement it. * docs/CHANGES: Updated. 2011-04-21 rainy6144 <rainy6144@gmail.com> [autofit] Blur CJK stems if too many to preserve their gaps. When there are too many stems to preserve their gaps in the rasterization of CJK Ideographs at a low resolution, blur the stems instead of showing clumped stems.

Patch submitted by anonymous reporter. * src/psaux/psobjs.c (ps_table_add): Use FT_PtrDist for pointer difference. 2011-04-11 Kan-Ru Chen <kanru@kanru.info> Fix reading of signed integers from files on 64bit platforms. Previously, signed integers were converted to unsigned integers, but this can fail because of sign extension. For example, 0xa344a1eb becomes 0xffffffffa344a1eb. We now do the reverse which is always correct because the integer size is the same during the cast from unsigned to signed. * include/freetype/internal/ftstream.h, src/base/ftstream.c (FT_Stream_Get*): Replace with... (FT_Stream_GetU*): Functions which read unsigned integers. Update all macros accordingly. * src/gzip/ftgzip.c (ft_gzip_get_uncompressed_size): Updated. 2011-04-07 Werner Lemberg <wl@gnu.org> Update Unicode ranges for CJK autofitter; in particular, add Hangul. * src/autofit/afcjk.c (af_cjk_uniranges): Update to Unicode 6.0. 2011-04-04 Werner Lemberg <wl@gnu.org> Fix formatting of autofit debug dumps. * src/autofit/afhints.c (af_glyph_hints_dump_points, af_glyph_hints_dump_segments, af_glyph_hints_dump_edges): Adjust column widths. 2011-03-30 Werner Lemberg <wl@gnu.org> * src/autofit/aftypes.h (AF_OutlineRec): Removed, unused. 2011-03-24 Werner Lemberg <wl@gnu.org> * src/cff/cfftypes.h (CFF_MAX_CID_FONTS): Increase to 256.

Patch suggested by Miles.Lau <sunliang_liu@foxitsoftware.com>. * src/cff/cffgload.c (cff_decoder_parse_charstrings): Emit tracing message for unknown operators and continue instead of exiting with a syntax error. 2011-02-01 Werner Lemberg <wl@gnu.org> [truetype] FT_LOAD_PEDANTIC now affects `prep' and `fpgm' also. * src/truetype/ttgload.c (tt_loader_init): Handle `FT_LOAD_PEDANTIC'. * src/truetype/ttobjs.c (tt_size_run_fpgm, tt_size_run_prep, tt_size_init_bytecode, tt_size_ready_bytecode): New argument to handle pedantic mode. * src/truetype/ttobjs.h: Updated. 2011-01-31 Werner Lemberg <wl@gnu.org> [truetype] Protect jump instructions against endless loops. * src/truetype/interp.c (DO_JROT, DO_JMPR, DO_JROF): Exit with error if offset is zero. 2011-01-31 Werner Lemberg <wl@gnu.org> [truetype] Improve handling of invalid references. * src/truetype/interp.c: Set even more TT_Err_Invalid_Reference error codes only if pedantic hinting is active. At the same time, try to provide sane values which hopefully allow useful continuation. Exception to this is CALL and LOOPCALL – due to possible stack corruption it is necessary to bail out. 2011-01-31 Werner Lemberg <wl@gnu.org> [truetype] Improve handling of stack underflow. * src/truetype/ttinterp.c (TT_RunIns, Ins_FLIPPT, Ins_DELTAP, Ins_DELTAC): Exit with error only if `pedantic_hinting' is set. Otherwise, try to do something sane. 2011-01-30 Werner Lemberg <wl@gnu.org> * src/sfnt/ttmtx.c (tt_face_load_hmtx): Fix tracing message. 2011-01-30 LIU Sun-Liang <sunliang_liu@foxitsoftware.com> [truetype]: Fix behaviour of MIAP for invalid arguments. * src/truetype/ttinterp.c (Ins_MIAP): Set reference points even in case of error. 2011-01-18 Werner Lemberg <wl@gnu.org> [truetype] Fix handling of MIRP instruction. Thanks to Greg Hitchcock who explained the issue. * src/truetype/ttinterp.c (Ins_MIRP): Replace a `>=' operator with `>' since the description in the specification is incorrect. This fixes, for example, glyph `two' in font `Helvetica Neue LT Com 65 medium' at 15ppem. 2011-01-15 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> Fix ARM assembly code in include/freetype/config/ftconfig.h. * include/freetype/config/ftconfig.h (FT_MulFix_arm): Copy the maintained code from builds/unix/ftconfig.in. Old GNU binutils could not accept the reduced syntax `orr %0, %2, lsl #16'. Un-omitted syntax like RVCT, `orr %0, %0, %2, lsl #16' is better. Reported by Johnson Y. Yan. The bug report by Qt developers is considered too. https://bugreports.qt.io/browse/QTBUG-6521 2011-01-15 Werner Lemberg <wl@gnu.org> [raster] Make bbox handling the same as with Microsoft's rasterizer. Right before B/W rasterizing, the bbox gets simply rounded to integers. This fixes, for example, glyph `three' in font `Helvetica Neue LT Com 65 Medium' at 11ppem. Thanks to Greg Hitchcock who explained this behaviour. * src/raster/ftrend1.c (ft_raster1_render): Implement it. 2011-01-15 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> Copy -mcpu=* & -march=* options from CFLAGS to LDFLAGS. * builds/unix/configure.raw: Consider recent gcc-standard flags to specify architecture in CFLAGS & LDFLAGS harmonization. Requested by Savannah bug #32114, to support multilib feature of BuildRoot SDK correctly. 2011-01-15 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> Fix off-by-one bug in CFLAGS & LDFLAGS harmonizer. * builds/unix/configure.raw: Some important options that included in CFLAGS but not in LDFLAGS are copied to LDFLAGS, but the last option in CFLAGS was not checked. 2011-01-13 Werner Lemberg <wl@gnu.org> [raster] Add undocumented drop-out rule to the other bbox side also. * src/raster/ftraster.c (Vertical_Sweep_Drop, Horizontal_Sweep_Drop): Implement it. 2011-01-13 Werner Lemberg <wl@gnu.org> [raster] Reduce jitter value. This catches a rendering problem with glyph `x' from Tahoma at 10ppem. It seems that the increase of the precision in the change from 2009-06-11 makes a larger jitter value unnecessary. * src/raster/ftraster.c (Set_High_Precision): Implement it. 2011-01-13 Werner Lemberg <wl@gnu.org> [raster] Handle drop-outs at glyph borders according to Microsoft. If a drop-out rule would switch on a pixel outside of the glyph's bounding box, use the right (or top) pixel instead. This is an undocumented feature, but some fonts like `Helvetica Neue LT Com 65 Medium' heavily rely on it. Thanks to Greg Hitchcock who explained this behaviour. * src/raster/ftraster.c (Vertical_Sweep_Drop, Horizontal_Sweep_Drop): Implement it. 2011-01-09 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> [cache] Fix Savannah bug #31923, patch drafted by Harsha. When a node comparator changes the cached nodes during the search of a node matching with queried properties, the pointers obtained before the function should be updated to prevent the dereference to freed or reallocated nodes. To minimize the rescan of the linked list, the update is executed when the comparator notifies the change of cached nodes. This change depends previous change: 38b272ffbbdaae276d636aec4ef84af407d16181 * src/cache/ftccache.h (FTC_CACHE_LOOKUP_CMP): Rescan the top node if the cached nodes are changed. * src/cache/ftccache.c (FTC_Cache_Lookup): Ditto. 2011-01-09 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> [cache] Notice if a cache query induced the node list change. Some node comparators (comparing the cache node contents and the properties specified by the query) can flush the cache node to prevent the cache inflation. The change may invalidate the pointers to the node obtained before the node comparison, so it should be noticed to the caller. The problem caused by the cache node changing is reported by Harsha, see Savannah bug #31923. * src/cache/ftccache.h (FTC_Node_CompareFunc): Add new argument `FT_Bool* list_changed' to indicate the change of the cached nodes to the caller. (FTC_CACHE_LOOKUP_CMP): Watch the change of the cached nodes by `_list_changed'. (FTC_CACHE_TRYLOOP_END): Take new macro argument `_list_changed' and update it when `FTC_Manager_FlushN' flushes any nodes. * src/cache/ftccback.h (ftc_snode_compare): Updated to fit with new FTC_Node_CompareFunc type. (ftc_gnode_compare): Ditto. * src/cache/ftcbasic.c: Include FT_INTERNAL_OBJECTS_H to use TRUE/FALSE macros. (ftc_basic_gnode_compare_faceid): New argument `FT_Bool* list_changed' to indicate the change of the cache nodes (anyway, it is always FALSE). * src/cache/ftccmap.c: Include FT_INTERNAL_OBJECTS_H to use TRUE/FALSE macros. (ftc_cmap_node_compare): New argument `FT_Bool* list_changed' to indicate the change of the cache nodes (anyway, it is always FALSE). (ftc_cmap_node_remove_faceid): Ditto. * src/cache/ftccache.c (FTC_Cache_NewNode): Pass a NULL pointer to `FTC_CACHE_TRYLOOP_END', because the result is not needed. (FTC_Cache_Lookup): Watch the change of the cache nodes by `list_changed'. (FTC_Cache_RemoveFaceID): Ditto. * src/cache/ftcglyph.c: Include FT_INTERNAL_OBJECTS_H to use TRUE/FALSE macros. (ftc_gnode_compare): New argument `FT_Bool* list_changed' to indicate the change of the cache nodes (anyway, it is always FALSE). (FTC_GNode_Compare): New argument `FT_Bool* list_changed' to be passed to `ftc_gnode_compare'. * src/cache/ftcglyph.h (FTC_GNode_Compare): Ditto. * src/cache/ftcsbits.c (ftc_snode_compare): New argument `FT_Bool* list_changed' to indicate the change of the cache nodes, anyway. It is updated by `FTC_CACHE_TRYLOOP'. (FTC_SNode_Compare): New argument `FT_Bool* list_changed' to be passed to `ftc_snode_compare'. * src/cache/ftcsbits.h (FTC_SNode_Compare): Ditto. 2011-01-09 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> [cache] Fit `FTC_GNode_Compare' to `FTC_Node_CompareFunc'. * src/cache/ftcglyph.h (FTC_GNode_Compare): Add the 3rd argument `FTC_Cache cache' to fit FTC_Node_CompareFunc prototype. * src/cache/ftcglyph.c (FTC_GNode_Compare): Ditto. Anyway, `cache' is not used by its child `ftc_gnode_compare'. 2011-01-09 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> [cache] Deduplicate the code to get the top node by a hash. There are several duplicated code fragments getting the top node from a cache by a given hash, like: idx = hash & cache->mask; if ( idx < cache->p ) idx = hash & ( cache->mask * 2 + 1 ); pnode = cache->buckets + idx; To remove duplication, a cpp-macro to do same work `FTC_NODE__TOP_FOR_HASH' is introduced. For non-inlined configuration, non-`ftc_get_top_node_for_hash' is also introduced. * src/cache/ftccache.h (FTC_NODE__TOP_FOR_HASH): Declare and implement inlined version. (FTC_CACHE_LOOKUP_CMP): Use `FTC_NODE__TOP_FOR_HASH'. * src/cache/ftccache.c (ftc_get_top_node_for_hash): Non-inlined version. (ftc_node_hash_unlink): Use `FTC_NODE__TOP_FOR_HASH'. (ftc_node_hash_link): Ditto. (FTC_Cache_Lookup): Ditto. 2011-01-09 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> [cache] inline-specific functions are conditionalized. * src/cache/ftcglyph.c (FTC_GNode_Compare): Conditionalized for inlined configuration. This function is a thin wrapper of `ftc_gnode_compare' for inlined `FTC_CACHE_LOOKUP_CMP' (see `nodecmp' argument). Under non-inlined configuration, `ftc_gnode_compare' is invoked by `FTC_Cache_Lookup', via `FTC_Cache->clazz.node_compare'. * src/cache/ftcglyph.h (FTC_GNode_Compare): Ditto. * src/cache/ftcsbits.c (FTC_SNode_Compare): Ditto, for `ftc_snode_compare'. * src/cache/ftcsbits.h (FTC_SNode_Compare): Ditto. 2011-01-09 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> [cache] Correct a type mismatch under non-inlined config. * src/cache/ftcglyph.h (FTC_GCACHE_LOOKUP_CMP): `FTC_GCache_Lookup' takes the node via a pointer `FTC_Node*', differently from cpp-macro `FTC_CACHE_LOOKUP_CMP'. 2011-01-06 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> Update Jamfile to include Bzip2 support. * Jamfile: Include src/bzip2 to project. Comments for lzw, gzip, bzip2 are changed to clarify that they are for compressed PCF fonts, not others. (e.g. compressed BDF fonts are not supported yet) 2011-01-05 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> Update Symbian project files to include Bzip2 support. Currently, it provides `FT_Stream_OpenBzip2' that returns unimplemented error always, to prevent unresolved symbol error for the applications designed for Unix systems. * builds/symbian/bld.inf: Include ftbzip2.h. * builds/symbian/freetype.mmp: Include ftbzip2.c. 2011-01-05 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> Update classic MacOS makefiles to include Bzip2 support. Currently, it provides `FT_Stream_OpenBzip2' that returns unimplemented error always, to prevent unresolved symbol error for the applications designed for Unix systems. * builds/mac/FreeType.m68k_cfm.make.txt: Include ftbzip2.c.o. * builds/mac/FreeType.m68k_far.make.txt: Ditto. * builds/mac/FreeType.ppc_carbon.make.txt: Include ftbzip2.c.x. * builds/mac/FreeType.ppc_classic.make.txt: Ditto. 2011-01-05 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> Update Amiga makefiles to include Bzip2 support. Currently, it provides `FT_Stream_OpenBzip2' that returns unimplemented error always, to prevent unresolved symbol error for the applications designed for Unix systems. * builds/amiga/makefile: Include bzip2.ppc.o built from ftbzip2.c. * builds/amiga/makefile.os4: Include bzip2.o built from ftbzip2.c. * builds/amiga/smakefile: Ditto. 2011-01-05 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> Update pkg-config tools to reflect Bzip2 support. * builds/unix/freetype-config.in: Include `-lbz2' to --libs output, if built with Bzip2 support. * builds/unix/freetype2.in: Ditto. 2011-01-05 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * builds/unix/configure.raw: Remove `SYSTEM_BZ2LIB' macro. SYSTEM_ZLIB is used to switch the builtin zlib source or system zlib source out of FreeType2. But ftbzip2 module has no builtin bzip2 library and always requires system bzip2 library.

If we encounter a space in a string then the sbit buffer is NULL, height and width are 0s. So the check in ftc_snode_compare will always pass for spaces (comparison with 255). Here the comments above the condition are proper but the implementation is not. When we create an snode I think it is the proper way to initialize the width to 255 and then put a check for being equal to 255 in snode compare function. * src/cache/ftcsbits.c (FTC_SNode_New): Initialize sbit widths with value 255.

Fix this. Partially undo change from 2010-10-15 by using ONE_PIXEL/4; this has been tested with demo images sent to the mailing list. See https://lists.gnu.org/archive/html/freetype-devel/2010-10/msg00055.html and later mails in this thread. 2010-10-28 Werner Lemberg <wl@gnu.org> [ftraster] Minor fixes.

Problem reported by Tom Bishop <wenlin@wenlin.com>; see thread starting with https://lists.gnu.org/archive/html/freetype/2010-10/msg00049.html * src/raster/ftraster.c (Line_Up): Replace FMulDiv with SMulDiv since the involved multiplication exceeds 32 bits. 2010-10-25 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> Revert a change of `_idx' type in `FTC_CACHE_LOOKUP_CMP'. * src/cache/ftccache.h (FTC_CACHE_LOOKUP_CMP): Revert the type of `_idx' from FT_PtrDist (by previous change) to original FT_UFast, to match with FT_CacheRec. 2010-10-24 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> [cache] Change the hash types to FT_PtrDist. On LLP64 platforms (e.g. Win64), FT_ULong (32-bit) variables are inappropriate to calculate hash values from the memory address (64-bit). The hash variables are extended from FT_ULong to FT_PtrDist and new hashing macro functions are introduced. The hash values on 16-bit memory platforms are changed, but ILP32 and LP64 are not changed. The hash value in the cache subsystem is not reverted to the memory address, so using signed type FT_PtrDist is safe. * src/cache/ftccache.h (_FTC_FACE_ID_HASH): New hash function to replace `FTC_FACE_ID_HASH' for portability. * src/cache/ftcmanag.h (FTC_SCALER_HASH): Replace `FTC_FACE_ID_HASH' by `_FTC_FACE_ID_HASH'. * src/cache/ftccmap.c (FTC_CMAP_HASH): Ditto. * src/cache/ftccache.h (FTC_NodeRec): The type of the member `hash' is changed from FT_UInt32 to FT_PtrDist. * src/cache/ftccache.h (FTC_Cache_Lookup): The type of the argument `hash' is changed from FT_UInt32 to FT_PtrDist. (FTC_Cache_NewNode): Ditto. * src/cache/ftccache.c (ftc_cache_add): Ditto. (FTC_Cache_Lookup): Ditto.

(FTC_SBitCache_LookupScaler): Ditto. * src/cache/ftccmap.c (FTC_CMapCache_Lookup): Ditto. * src/cache/ftccache.h (FTC_CACHE_LOOKUP_CMP): Ditto. Also the type of the internal variable `_idx' is changed to FT_PtrDist from FT_UFast for better pointer calculation. 2010-10-24 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> [cache] Hide internal macros incompatible with LLP64. `FT_POINTER_TO_ULONG', `FTC_FACE_ID_HASH', and `FTC_IMAGE_TYPE_HASH' are enclosed by FT_CONFIG_OPTION_OLD_INTERNALS and hidden from normal clients. For the history of these macros, see the investigation: https://lists.gnu.org/archive/html/freetype/2010-10/msg00022.html 2010-10-24 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> Change the type of `FT_MEM_VAL' from FT_ULong to FT_PtrDist. On LLP64 platforms (e.g. Win64), unsigned long (32-bit) cannot cover the memory address (64-bit). `FT_MEM_VAL' is used for hashing only and not dereferred, so using signed type FT_PtrDist is safe. * src/base/ftdbgmem.c (FT_MEM_VAL): Change the type of the return value from FT_ULong to FT_PtrDist. (ft_mem_table_resize): The type of hash is changed to FT_PtrDist. (ft_mem_table_get_nodep): Ditto. 2010-10-24 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> Replace "%lx" for memory address by "%p", LLP64 platforms. On LLP64 platforms (e.g. Win64), long (32-bit) cannot cover the memory address (64-bit). Also the casts from the pointer type to long int should be removed to preserve the address correctly. * src/raster/ftraster.c (New_Profile): Replace "%lx" by "%p". (End_Profile) Ditto. * src/truetype/ttinterp.c (Init_Context): Ditto. 2010-10-15 Alexei Podtelezhnikov <apodtele@gmail.com> Fix thinko in spline flattening. FT_MAX_CURVE_DEVIATION is dependent on the value of ONE_PIXEL. * src/smooth/ftgrays.c (FT_MAX_CURVE_DEVIATION): Remove it and replace it everywhere with ONE_PIXEL/8. 2010-10-13 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> [raccess] Skip unrequired resource access rules by Darwin VFS. When a resource fork access rule by Darwin VFS could open the resource fork but no font is found in it, the rest of rules by Darwin VFS are skipped. It reduces the warnings of the deprecated resource fork access method by recent Darwin kernel. Fix MacPorts ticket #18859: https://trac.macports.org/ticket/18859 * src/base/ftobjs.c (load_face_in_embedded_rfork): When `FT_Stream_New' returns FT_Err_Cannot_Open_Stream, it means that the file is possible to be `fopen'-ed but zero-sized. Also there is a case that the resource fork is not zero-sized, but no supported font exists in it. If a rule by Darwin VFS falls into such cases, there is no need to try other Darwin VFS rules anymore. Such cases are marked by vfs_rfork_has_no_font. If it is TRUE, the Darwin VFS rules are skipped. 2010-10-13 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> [raccess] Grouping resource access rules based on Darwin VFS. MacOS X/Darwin kernel supports a few tricky methods to access a resource fork via ANSI C or POSIX interface. Current resource fork accessor tries all possible methods to support all kernels. But if a method could open a resource fork but no font is found, there is no need to try other methods older than tested method. To determine whether the rule index is for Darwin VFS, a local function `ftrfork.c::raccess_rule_by_darwin_vfs' is introduced. To use this function in ftobjs.c etc but it should be inlined, it is exposed by ftbase.h. * src/base/ftrfork.c (FT_RFork_Rule): New enum type to identify the rules to access the resource fork. (raccess_guess_rec): New structure to bind the rule function and rule enum type. (FT_Raccess_Guess): The list of the rule functions is replaced by (raccess_guess_table): This. This is exposed to be used by other intra module functions. (raccess_rule_by_darwin_vfs): A function to return a boolean if the rule specified by the rule index is based on Darwin VFS. 2010-10-13 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> Prevent to open a FT_Stream for zero-sized file on non-Unix. builds/unix/ftsystem.c prevents to open an useless stream from zero-sized file and returns FT_Err_Cannot_Open_Stream, but the stream drivers for ANSI C, Amiga and VMS return useless streams. For cross-platform consistency, all stream drivers should act same. * src/base/ftsystem.c (FT_Stream_Open): If the size of the opened file is zero, FT_Err_Cannot_Open_Stream is returned. * builds/amiga/src/base/ftsystem.c (FT_Stream_Open): Ditto. * src/vms/ftsystem.c (FT_Stream_Open): Ditto. 2010-10-12 Werner Lemberg <wl@gnu.org> [truetype] Fix Savannah bug #31310. * src/truetype/ttgxvar.c (ft_var_readpackedpoints): Protect against invalid `runcnt' values. 2010-10-08 Chris Liddell <chris.liddell@artifex.com> [sfnt] Fix Savannah bug #31275. * src/sfnt/ttpost.c: Include FT_INTERNAL_DEBUG_H. 2010-10-06 Werner Lemberg <wl@gnu.org> [truetype] Improve error handling of `SHZ' bytecode instruction.

Information provided by Alan Coopersmith <alan.coopersmith@oracle.com>. 2010-05-10 Ken Sharp <ken.sharp@artifex.com> [psaux] Fix Savannah bug #29846. Previously we discovered fonts which used `setcurrentpoint' to set the initial point of a contour to 0,0. This caused FreeType to raise an error, because the `setcurrentpoint' operator is only supposed to be used with the results from an OtherSubr subroutine. This was fixed by simply ignoring the error and carrying on. Now we have found a font which uses setcurrentpoint to actually establish a non-zero point for a contour during the course of a glyph program. FWIW, these files may be produced by an application called `Intaglio' on the Mac, when converting TrueType fonts to Type 1. The fix allows the new invalid behaviour, the old invalid behaviour and real proper usage of the operator to work the same way as Adobe interpreters apparently do. * src/psaux/t1decode.c (t1_decoder_parse_charstrings): Make `setcurrentpoint' use the top two elements of the stack to establish unconditionally the current x and y coordinates. Make the `flex' subroutine handling (OtherSubr 0) put the current x,y coordinates onto the stack, instead of two dummy uninitialised values. 2010-04-14 Ken Sharp <ken.sharp@artifex.com> [psaux] Fix Savannah bug #29444. * src/psaux/psobjs.c (t1_builder_start_point): Accept (invalid) `lineto' immediately after `hsbw', in accordance with Acrobat, GS, and others. 2010-04-14 Michał Cichoń <thedmd@artifexmundi.com> [psaux] Fix Savannah bug #27999. * src/cache/ftcmanag.c (FTC_Manager_RemoveFaceID): Only remove selected entry, not all. 2010-04-06 Jonathan Kew <jfkthame@gmail.com> [truetype] Add overflow check to `fvar' table. * src/truetype/ttgxvar.c (TT_Get_MM_Var): Check axis and instance count. 2010-04-05 Ken Sharp <ken.sharp@artifex.com> [raster] Fix Savannah bug #29335. * src/raster/ftraster.c (Line_Up): Use slow multiplication to prevent overflow. This shouldn't have any serious impact on speed, however. 2010-04-05 Werner Lemberg <wl@gnu.org> Add new function `FT_Library_SetLcdFilterWeights'. This is based on code written by Lifter <https://unixforum.org/index.php?showuser=11691>. It fixes FreeDesktop bug #27386. * src/base/ftlcdfil.c (FT_Library_SetLcdFilterWeights): New function. * include/freetype/ftlcdfil.h: Updated. * docs/CHANGES: Updated. 2010-04-01 John Tytgat <John.Tytgat@esko.com> [truetype] Fix Savannah bug #29404. * src/truetype/ttgload.c: Revert change 2752bd1a (check on bit 1 of `head' table of TrueType fonts). 2010-03-14 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> Fix `multi build' for Tytgat's CFF driver improvement. * src/base/cffload.h (cff_index_get_name): Added. 2010-03-12 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> Remove duplicated inclusion of `FT_OUTLINE_H' in ftobjs.c. * src/base/ftobjs.c: Remove 2nd inclusion of `FT_OUTLINE_H'. 2010-03-11 Chris Liddell <chris.liddell@artifex.com> [raster] Fix Savannah bug #27442. * src/raster/ftraster.c (ft_black_reset): Fix `buffer_size'. 2010-03-09 Werner Lemberg <wl@gnu.org> [cff] Remove unused variable. Reported by Graham. * src/cff/cffparse.c (cff_parse_real): Remove `rest'. 2010-03-02 John Tytgat <John.Tytgat@esko.com> [cff] Improve CFF string (especially glyphname) lookup performance. We do this by avoiding memory allocation and file I/O. This is Savannah patch #7104. * src/cff/cfftypes.h: Include PS cmaps service and FT_INTERNAL_POSTSCRIPT_HINTS_H. (CFF_SubFontRec): Remove `num_local_subrs'. (CFF_FontRec): Add `num_strings', `strings', and `string_pool' fields. Remove `string_index' and `num_global_subrs' fields. Use real types instead of `void' for `pshinter' and `psnames' fields. * src/cff/cffload.c: Don't include PS cmaps service. (cff_index_get_pointers): Add `pool' parameter which allows inserting an extra NUL character for each String INDEX entry. (cff_index_get_name): Make it a local function. (cff_index_get_string): New function. (cff_subfont_load): Updated. (cff_font_load): Initialize `num_strings', `strings', and `string_pool' fields in the `CFF_FontRec' structure.

2014-12-30 Werner Lemberg <wl@gnu.org> * Version 2.5.5 released. ========================= Tag sources with `VER-2-5-5'. * docs/VERSION.DLL: Update documentation and bump version number to 2.5.5. * README, Jamfile (RefDoc), builds/windows/vc2005/freetype.vcproj, builds/windows/vc2005/index.html, builds/windows/vc2008/freetype.vcproj, builds/windows/vc2008/index.html, builds/windows/vc2010/freetype.vcxproj, builds/windows/vc2010/index.html, builds/windows/visualc/freetype.dsp, builds/windows/visualc/freetype.vcproj, builds/windows/visualc/index.html, builds/windows/visualce/freetype.dsp, builds/windows/visualce/freetype.vcproj, builds/windows/visualce/index.html, builds/wince/vc2005-ce/freetype.vcproj, builds/wince/vc2005-ce/index.html, builds/wince/vc2008-ce/freetype.vcproj, builds/wince/vc2008-ce/index.html: s/2.5.4/2.5.5/, s/254/255/. * include/freetype/freetype.h (FREETYPE_PATCH): Set to 5. * builds/unix/configure.raw (version_info): Set to 17:4:11. * CMakeLists.txt (VERSION_PATCH): Set to 5. * docs/CHANGES: Updated. * builds/toplevel.mk (dist): Fix typos. 2014-12-24 Alexei Podtelezhnikov <apodtele@gmail.com> [base] Formatting and nanooptimizations. * src/base/ftcalc.c, * src/base/fttrigon.c: Revise sign restoration. 2014-12-13 Werner Lemberg <wl@gnu.org> * src/pcf/pcfread.c (pcf_read_TOC): Improve fix from 2014-12-08. 2014-12-11 Werner Lemberg <wl@gnu.org> * builds/toplevel.mk (dist): Use older POSIX standard for `tar'. Apparently, BSD tar isn't capable yet of handling POSIX-1.2001 (contrary to GNU tar), so force the POSIX-1.1988 format. Problem reported by Stephen Fisher <sfisher@SDF.ORG>. 2014-12-11 Werner Lemberg <wl@gnu.org> * src/type42/t42parse.c (t42_parse_sfnts): Reject invalid TTF size. 2014-12-11 Werner Lemberg <wl@gnu.org> * src/base/ftobjs.c (FT_Get_Glyph_Name): Fix off-by-one check. Problem reported by Dennis Felsing <dennis@felsin9.de>. 2014-12-11 Werner Lemberg <wl@gnu.org> * src/type42/t42parse.c (t42_parse_sfnts): Check `string_size'. Problem reported by Dennis Felsing <dennis@felsin9.de>. 2014-12-09 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> [gxvalid] Fix a naming convention conflicting with ftvalid. See previous changeset for otvalid. * src/gxvalid/{gxvcommn.h, gxvmort.h, gxvmorx.h}: Replace `valid' by `gxvalid'. * src/gxvalid/{gxvbsln.c, gxvcommn.c, gxvfeat.c, gxvjust.c, gxvkern.c, gxvlcar.c, gxvmort.c, gxvmort0.c, gxvmort1.c, gxvmort2.c, gxvmort4.c, gxvmort5.c, gxvmorx.c, gxvmorx0.c, gxvmorx1.c, gxvmorx2.c, gxvmorx4.c, gxvmorx5.c, gxvopbd.c, gxvprop.c, gxvtrak.c}: Replace `valid' by `gxvalid' if it is typed as GXV_Validator. 2014-12-09 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> [otvalid] Fix a naming convention conflicting with ftvalid. Some prototypes in ftvalid.h use `valid' for the variables typed as FT_Validator. Their implementations in src/base/ ftobjs.c and utilizations in src/sfnt/ttcmap.c do similar. Some macros in otvcommn.h assume the exist of the variable `valid' typed as OTV_Validator in the caller. Mixing these two conventions cause invalid pointer conversion and unexpected SEGV in longjmp. To prevent it, all variables typed as OTV_Validator are renamed to `otvalid'. * src/otvalid/otvcommn.h: Replace `valid' by `otvalid'. * src/otvalid/{otvcommn.c, otvbase.c, otvgdef.c, otvgpos.c, otvgsub.c, otvjstf.c, otvmath.c}: Replace `valid' by `otvalid' if it is typed as OTV_Validator. 2014-12-09 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> [ftvalid] Introduce FT_THROW() in FT_INVALID_XXX macros. Original patch is designed by Werner Lemberg. Extra part for otvalid and gxvalid are added by suzuki toshiya, see discussion: https://lists.nongnu.org/archive/html/freetype-devel/2014-12/msg00002.html https://lists.nongnu.org/archive/html/freetype-devel/2014-12/msg00007.html * include/internal/ftvalid.h: Introduce FT_THROW() in FT_INVALID_(). * src/gxvalid/gxvcommn.h: Ditto. * src/otvalid/otvcommn.h: Ditto. 2014-12-08 Werner Lemberg <wl@gnu.org> [pcf] Fix Savannah bug #43774. Work around `features' of X11's `pcfWriteFont' and `pcfReadFont' functions. Since the PCF format doesn't have an official specification, we have to exactly follow these functions' behaviour. The problem was unveiled with a patch from 2014-11-06, fixing issue #43547. * src/pcf/pcfread.c (pcf_read_TOC): Don't check table size for last element. Instead, assign real size. 2014-12-07 Werner Lemberg <wl@gnu.org> Work around a bug in Borland's C++ compiler. See http://qc.embarcadero.com/wc/qcmain.aspx?d=118998 for Borland's bug tracker entry. Reported by Yuliana Zigangirova <zigangirova@inbox.ru>, https://lists.gnu.org/archive/html/freetype-devel/2014-04/msg00001.html. * include/internal/ftvalid.h (FT_ValidatorRec), src/smooth/ftgrays.c (gray_TWorker_): Move `ft_jmp_buf' field to be the first element. 2014-12-07 Werner Lemberg <wl@gnu.org> */*: Decorate hex constants with `U' and `L' where appropriate. 2014-12-07 Werner Lemberg <wl@gnu.org> [truetype] Prevent memory leak for buggy fonts. * src/truetype/ttobjs.c (tt_size_done): Unconditionally call `tt_size_done_bytecode'. 2014-12-06 Werner Lemberg <wl@gnu.org> * Version 2.5.4 released. ========================= Tag sources with `VER-2-5-4'. * docs/VERSION.DLL: Update documentation and bump version number to 2.5.4. * README, Jamfile (RefDoc), builds/windows/vc2005/freetype.vcproj, builds/windows/vc2005/index.html, builds/windows/vc2008/freetype.vcproj, builds/windows/vc2008/index.html, builds/windows/vc2010/freetype.vcxproj, builds/windows/vc2010/index.html, builds/windows/visualc/freetype.dsp, builds/windows/visualc/freetype.vcproj, builds/windows/visualc/index.html, builds/windows/visualce/freetype.dsp, builds/windows/visualce/freetype.vcproj, builds/windows/visualce/index.html, builds/wince/vc2005-ce/freetype.vcproj, builds/wince/vc2005-ce/index.html, builds/wince/vc2008-ce/freetype.vcproj, builds/wince/vc2008-ce/index.html: s/2.5.3/2.5.4/, s/253/254/. * include/freetype/freetype.h (FREETYPE_PATCH): Set to 4. * builds/unix/configure.raw (version_info): Set to 17:3:11. * CMakeLists.txt (VERSION_PATCH): Set to 4. * docs/CHANGES: Updated. 2014-12-04 Werner Lemberg <wl@gnu.org> docs/CHANGES: Updated, formatted. 2014-12-04 Dave Arnold <darnold@adobe.com> [cff] Modify an FT_ASSERT. * src/cff/cf2hints.c (cf2_hintmap_map): After the fix for Savannah bug #43661, the test font `...aspartam.otf' still triggers an FT_ASSERT. Since hintmap still works with count==0, ... (cf2_glyphpath_lineTo, cf2_glyphpath_curveTo): ... add that term to suppress the assert. 2014-12-04 Dave Arnold <darnold@adobe.com> [cff] Fix Savannah bug #43661. * src/cff/cf2intrp.c (cf2_interpT2CharString) <cf2_cmdHSTEM, cf2_cmdVSTEM, cf2_cmdHINTMASK>: Don't append to stem arrays after hintmask is constructed. * src/cff/cf2hints.c (cf2_hintmap_build): Add defensive code to avoid reading past end of hintmask. 2014-12-03 Werner Lemberg <wl@gnu.org> docs/CHANGES: Updated. 2014-12-03 Werner Lemberg <wl@gnu.org> [autofit] Better fix for conversion specifiers in debug messages. Using `%ld' for pointer differences causes warnings on 32bit platforms. The correct type would be (the relatively new) `%td', however, this is missing on some important platforms. This patch improves the change from 2014-11-28. * src/autofit/afhints.c (AF_INDEX_NUM): Use `int' typecast. Our pointer differences are always sufficiently small. (af_glyph_hints_dump_points, af_glyph_hints_dump_segments, af_glyph_hints_dump_edge): Revert to `%d' and use `AF_INDEX_NUM'. 2014-12-03 Werner Lemberg <wl@gnu.org> FT_Sfnt_Tag: s/ft_sfnt_xxx/FT_SFNT_XXX/ for orthogonality. All public FreeType enumeration and flag values are uppercase... * include/tttables.h (FT_Sfnt_Tag): Implement it. For backward compatibility, retain the old values as macros. * src/base/ftfstype.c (FT_Get_FSType_Flags), src/sfnt/sfdriver.c (get_sfnt_table): Updated. 2014-12-02 Werner Lemberg <wl@gnu.org> * include/*: Improve structure of documentation. . Add and update many `<Order>' tags. . Apply various documentation fixes. . Remove details to deprecated (or never implemented) data. 2014-12-02 Werner Lemberg <wl@gnu.org> [docmaker] Always handle `<Order>' section elements. Previously, those elements were handled only for sections present in a `<Sections>' chapter element. * src/tools/docmaker/content.py (ContentProcessor::finish): Implement it. 2014-12-02 Werner Lemberg <wl@gnu.org> [docmaker] Properly handle empty rows in Synopsis. * src/tools/docmaker/tohtml.py (HtmlFormatter::section_enter): Emit ` ' for empty fields. 2014-12-02 Werner Lemberg <wl@gnu.org> [docmaker] Thinko. * src/tools/docmaker/content.py (DocBlock::get_markup_words_all): Emit `/empty/' string for first element also. 2014-12-02 Werner Lemberg <wl@gnu.org> [docmaker] Honour empty lines in `<Order>' section element. This greatly improves the readability of the `Synopsis' links. * src/tools/docmaker/content.py (DocBlock::get_markup_words_all): Insert string `/empty/' between items. * src/tools/docmaker/formatter.py (Formatter::section_dump): Make it robust against nonexistent keys. * src/tools/docmaker/tohtml.py (HtmlFormatter::section_enter): Emit empty <td> elements for `/empty/'. 2014-12-02 Werner Lemberg <wl@gnu.org> [docmaker] Ensure Python 3 compatibility. * src/tools/docmaker/content.py (ContentProcessor::set_section, ContentProcessor::finish): Replace `has_key' function with `in' keyword. * src/tools/docmaker/formatter.py (Formatter::__init__): Replace sorting function with a key generator. (Formatter::add_identifier): Replace `has_key' function with `in' keyword. * src/tools/docmaker/tohtml.py (HtmlFormatter::html_source_quote): Replace `has_key' function with `in' keyword. (HtmlFormatter::index_exit, HtmlFormatter::section_enter): Use integer division. s/<>/>/. * src/tools/docmaker/utils.py: Import `itertools'. (index_sort): Replaced by... (index_key): ... this new key generator (doing exactly the same). 2014-11-29 Werner Lemberg <wl@gnu.org> [docmaker] Don't output a block multiple times. This bug was hidden by not processing all lines of `<Order>' blocks. * src/tools/docmaker/formatter.py (Formatter::section_dump): Filter out field names. 2014-11-29 Werner Lemberg <wl@gnu.org> [docmaker] Use field values as HTML link targets where possible. * src/tools/docmaker/tohtml.py (HtmlFormatter::make_block_url): Accept second, optional argument to specify a name. (HtmlFormatter::html_source_quote): Link to field ID if possible. (HtmlFormatter::print_html_field_list): Emit `id' attribute. 2014-11-29 Werner Lemberg <wl@gnu.org> [docmaker] Allow empty lines in `<Order>' blocks. Before this patch, the suggested order of entries stopped at the first empty line. Obviously, nobody noticed that this problem caused a much reduced set of links in the `Synopsis' sections; in particular, the `<Order>' blocks contain a lot of entries that wouldn't be listed otherwise... * src/tools/docmaker/content.py (DocBlock::get_markup_words_all): New function to iterate over all items. (DocSection::process): Use it. 2014-11-29 Werner Lemberg <wl@gnu.org> * src/tools/docmaker/sources.py (column) [Format 2]: Fix regexp. After the single asterisk there must be no other immediately following asterisk. 2014-11-29 Werner Lemberg <wl@gnu.org> * src/tools/docmaker/tohtml.py: Improve CSS for vertical spacing. 2014-11-29 Werner Lemberg <wl@gnu.org> [docmaker] Improve HTML code for table of contents. * src/tools/docmaker/tohtml.py: Introduce a new table class `toc', together with proper CSS. 2014-11-29 Werner Lemberg <wl@gnu.org> [docmaker] Provide higher-level markup and simplify HTML. * src/tools/docmaker/tohtml.py: Instead of using extraneous `<div>' elements, use CSS descendants (of class `section') to format the data. Also remove redundant <p> and <br> elements, replacing them with proper CSS. Globally reduce page width to 75%. (block_header): Rename <div> class to `section'. 2014-11-29 Werner Lemberg <wl@gnu.org> [docmaker] Add `top' links after blocks. * src/tools/docmaker/tohtml.py (block_footer_middle): Implement it. 2014-11-29 Werner Lemberg <wl@gnu.org> * src/tools/docmaker/tohtml.py: Improve CSS for fields. Make fields align horizontally relative to full line width. 2014-11-29 Werner Lemberg <wl@gnu.org> * src/tools/docmaker/tohtml.py: Fix index and TOC templates. This thinko was introduced 2014-11-27. 2014-11-28 Werner Lemberg <wl@gnu.org> [docmaker] Format field lists with CSS. This also simplifies the inserted HTML code. * src/tools/docmaker/tohtml.py (HtmlFormatter::print_html_field_list): Do it. 2014-11-28 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> Fix compiler warning to the comparison between signed and unsigned variable. * src/pfr/pfrsbit.c (pfr_slot_load_bitmap): Fix the comparison between `ypos + ysize' and FT_INT_{MAX,MIN}. 2014-11-28 Werner Lemberg <wl@gnu.org> [docmaker] Replace empty `<td>' with CSS. * src/tools/docmaker/tohtml.py (HtmlFormatter::section_enter): Do it. 2014-11-28 Werner Lemberg <wl@gnu.org> [docmaker] Replace some `<table>' tags with `<h4>' and `<div>'. * src/tools/docmaker/tohtml.py (marker_*): Use `<h4>'. (source_*): Use `<div>'. (HtmlFormatter::block_enter): s/<h4>/<h3>/. 2014-11-28 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> Fix compiler warning to conversion specifiers in debug messages. * src/autofit/afhints.c (af_glyph_hints_dump_points): Add length modifier to dump long integers. (af_glyph_hints_dump_segments, af_glyph_hints_dump_edges): Ditto. 2014-11-27 Werner Lemberg <wl@gnu.org> * src/tools/docmaker/tohtml.py: Use more CSS for index. 2014-11-27 Werner Lemberg <wl@gnu.org> [docmaker] Replace `name' attribute of `<a>' with `id'. * src/tools/docmaker/tohtml.py (HtmlFormatter::block_enter): Do it. 2014-11-27 Werner Lemberg <wl@gnu.org> * src/tools/docmaker/tohtml.py: Remove remaining `width' attributes. For `Index' and `TOC' links, we now simply use the `text-align' CSS property of `<td>' to enforce flush-left and flush-right, eliminating the hack with an empty, full-width `<td>' element inbetween. The change also enforces the same (smaller) size for all index and TOC links. 2014-11-27 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * src/cff/cf2font.c: Include `ftcalc.h' to use FT_MSB(), cf2font.c could not find it under `make multi' build. 2014-11-27 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * src/smooth/ftsmooth.c (ft_smooth_render_generic): Remove unrequired negative value check for `width' and `height'. 2014-11-27 Werner Lemberg <wl@gnu.org> * src/tools/docmaker/tohtml.py: More HTML table refactoring. Replace some `<table>' tags with `<div>' to simplify structure. Move `bgcolor' attribute to CSS. Replace most `width' attributes with CSS. The remaining instances (providing a similar effect as LaTeX's `\hfill' command) are removed in a later patch. 2014-11-27 Werner Lemberg <wl@gnu.org> * src/tools/docmaker/tohtml.py: Replace <font> with CSS. 2014-11-27 Werner Lemberg <wl@gnu.org> * src/tools/docmaker/tohtml.py: Center <table> with CSS. 2014-11-27 Werner Lemberg <wl@gnu.org> * src/tools/docmaker/tohtml.py: Replace `<center>' with `<div>'. 2014-11-27 Werner Lemberg <wl@gnu.org> * src/tools/docmaker/tohtml.py: Remove redundant `<center>' tags. This starts a series of commits into the direction of generating valid HTML 5 code, especially using much more CSS. 2014-11-27 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> Prevent too negative values (< FT_INT_MIN) in bitmap metrics, suggested by Alexei. * src/pfr/pfrsbit.c (pfr_slot_load_bitmap): Prevent too negative values in `xpos' and `ypos + ysize'. * src/smooth/ftsmooth.c (ft_smooth_render_generic): Prevent too negative values in `x_left' and `y_top'. Either negative values in `width' and `height' are checked. 2014-11-27 Werner Lemberg <wl@gnu.org> [docmaker] Produce better HTML code. * src/tools/docmaker/tohtml.py: Always use double quotes for attribute values. (source_footer): Close `td' and `tr' groups. 2014-11-27 Werner Lemberg <wl@gnu.org> Use better way to disable creation of .pyc files for `make refdoc'. Python 2.6 was released in 2008... * builds/freetype.mk (refdoc): Use python's `-B' option. * builds/detect.mk (std_setup, dos_setup): Mention required python version for `refdoc' target. 2014-11-27 Werner Lemberg <wl@gnu.org> * src/tools/docmaker/sources.py (re_bold, re_italic): Use non-grouping parentheses. * src/tools/docmaker/tohtml.py (HtmlFormatter::make_html_word): Updated. 2014-11-27 Werner Lemberg <wl@gnu.org> * src/base/ftobjs.c (FT_Get_Glyph_Name): Fix compiler warning. Introduced in previous change. Reported by Alexei. 2014-11-26 Werner Lemberg <wl@gnu.org> * src/*: Add checks for parameters of API functions where missing. `API functions' are functions tagged with `FT_EXPORT_DEF'. Besides trivial fixes, the following changes are included, too. * src/base/ftbdf.c (FT_Get_BDF_Charset_ID, FT_Get_BDF_Property): Set error code if no service is available. * src/base/ftinit.c (FT_Done_FreeType): Change return value for invalid `library' parameter to `Invalid_Library_Handle'. * src/base/ftobjs.c (FT_New_Size): Change return value for invalid `asize' parameter to `Invalid_Argument'. * src/base/ftoutln.c (FT_Outline_Copy): Change return value for invalid `source' and `target' parameters to `Invalid_Outline'.

We use a cast to indicate that we intentionally ignore a function's return value. However, this doesn't apply to API functions where errors can only happen for trivially invalid input. * src/base/ftstroke.c (FT_Glyph_Stroke, FT_Glyph_StrokeBorder), src/base/ftsynth.c (FT_GlyphSlot_Embolden), src/cff/cffgload.c (cff_slot_load), src/pfr/pfrdrivr.c (pfr_get_kerning), src/type1/t1load.c (parse_encoding), src/type42/t42parse.c (t42_parse_encoding): Do it. 2014-11-25 Werner Lemberg <wl@gnu.org> [Savannah bug #43682] Change some signatures to `void' return type. * include/internal/pshints.h (PSH_Globals_SetScaleFunc), include/internal/sfnt.h (TT_Get_Metrics_Func), src/pshinter/pshglob.c (psh_globals_set_scale), src/pshinter/pshrec.c (ps_hints_init), src/sfnt/ttmtx.c (tt_face_get_metrics), src/truetype/ttinterp.c (TT_Goto_CodeRange, TT_Set_CodeRange, TT_Clear_CodeRange, TT_Done_Context, TT_Save_Context): Do it. * src/pshinter/pshglob.h, src/pshinter/pshrec.h, src/sfnt/ttmtx.h, src/truetype/ttgload.c (TT_Hint_Glyph), src/truetype/ttinterp.c (TT_Run_Context), src/truetype/ttinterp.h, src/truetype/ttobjs.c (tt_size_run_fpgm, tt_size_run_prep): Updated. 2014-11-24 Werner Lemberg <wl@gnu.org> Remove all code related to FT_MAX_CHARMAP_CACHEABLE. This is no longer used. * src/base/ftobjs.c, src/cache/ftccmap.c, src/cff/cffobjs.c, src/sfnt/ttcmap.c: Do it. 2014-11-24 Werner Lemberg <wl@gnu.org> [sfnt] Fix Savannah bug #43680. This adds an additional constraint to make the fix from 2013-01-25 really work. * src/sfnt/ttsbit.c (tt_sbit_decoder_load_image) <index_format==4>: Check `p' before `num_glyphs'. 2014-11-24 Werner Lemberg <wl@gnu.org> [truetype] Fix Savannah bug #43679. * src/truetype/ttpload.c (tt_face_load_hdmx): Check minimum size of `record_size'. 2014-11-24 Jarkko Pöyry <jarkko.poyry@gmail.com> [cff, pfr, psaux, winfonts] Fix Savannah bug #43676. Don't cast cmap init function pointers to an incompatible type. Without this patch, the number of parameters between declaration and the real signature differs. Calling such a function results in undefined behavior. ISO/IEC 9899:TC3 (Committee Draft September 7, 2007) 6.5.2.2 Function calls 9 If the function is defined with a type that is not compatible with the type (of the expression) pointed to by the expression that denotes the called function, the behavior is undefined. On certain platforms (c -> js with emscripten) this causes termination of execution or invalid calls because in the emscripten implementation, function pointers of different types are stored in different pointer arrays. Incorrect pointer type here results in indexing of an incorrect array. * src/cff/cffcmap.c (cff_cmap_encoding_init, cff_cmap_unicode_init), src/pfr/pfrcmap.c (pfr_cmap_init), src/psaux/t1cmap.c t1_cmap_standard_init, t1_cmap_expert_init, t1_cmap_custom_init, t1_cmap_unicode_init), src/winfonts/winfnt.c (fnt_cmap_init): Fix signature. 2014-11-24 Werner Lemberg <wl@gnu.org> [sfnt] Fix Savannah bug #43672. * src/sfnt/ttkern.c (tt_face_load_kern): Use correct value for minimum table length test. 2014-11-24 Werner Lemberg <wl@gnu.org> [type1, type42] Another fix for Savannah bug #43655. * src/type1/t1load.c (parse_charstrings), src/type42/t42parse.c (t42_parse_charstrings): Add another boundary testing. 2014-11-24 Werner Lemberg <wl@gnu.org> [docmaker] Formatting, copyright, improved documentation. * src/tools/docmaker/*: No code changes besides trivial modifications. 2014-11-22 Werner Lemberg <wl@gnu.org> [bdf] Fix Savannah bug #43660. * src/bdf/bdflib.c (_bdf_parse_glyphs) <"ENDFONT">: Check `_BDF_GLYPH_BITS'. 2014-11-22 Werner Lemberg <wl@gnu.org> [type42] Allow only embedded TrueType fonts. This is a follow-up to Savannah bug #43659. * src/type42/t42objs.c (T42_Face_Init): Exclusively use the `truetype' font driver for loading the font contained in the `sfnts' array. 2014-11-22 Werner Lemberg <wl@gnu.org> [type42] Fix Savannah bug #43659. * src/type42/t42objs.c (T42_Open_Face): Initialize `face->ttf_size'. * src/type42/t42parse.c (t42_parse_sfnts): Always set `face->ttf_size' directly. This ensures a correct stream size in the call to `FT_Open_Face', which follows after parsing, even for buggy input data. Fix error messages. 2014-11-22 Werner Lemberg <wl@gnu.org> [cff] Fix Savannah bug #43658. * src/cff/cf2ft.c (cf2_builder_lineTo, cf2_builder_cubeTo): Handle return values of point allocation routines. 2014-11-22 Werner Lemberg <wl@gnu.org> [sfnt] Fix Savannah bug #43656. * src/sfnt/ttcmap.c (tt_cmap4_validate): Fix order of validity tests. 2014-11-21 Werner Lemberg <wl@gnu.org> [type1, type42] Fix Savannah bug #43655. * src/type1/t1load.c (parse_charstrings), src/type42/t42parse.c (t42_parse_charstrings): Fix boundary testing. 2014-11-21 Werner Lemberg <wl@gnu.org> * src/pcf/pcfread.c (pcf_get_metrics): Sanitize invalid metrics. 2014-11-21 Werner Lemberg <wl@gnu.org> [ftlcdfil] Obey flow direction. * src/base/ftlcdfil.c (_ft_lcd_filter_fir, _ft_lcd_filter_legacy): Handle `up' flow. 2014-11-21 Werner Lemberg <wl@gnu.org> * src/base/ftbitmap.c (FT_Bitmap_Convert): Improve. This commit completes argument checks and adds support for different flow directions. 2014-11-21 Werner Lemberg <wl@gnu.org> * src/base/ftbitmap.c (FT_Bitmap_Copy): Improve. This commit adds argument checks and support for different flow directions. 2014-11-20 Werner Lemberg <wl@gnu.org> * src/base/ftbitmap.c (FT_Bitmap_New): Check argument. 2014-11-19 Werner Lemberg <wl@gnu.org> Change some fields in `FT_Bitmap' to unsigned type. This doesn't break ABI. * include/ftimage.h (FT_Bitmap): Make `rows', `width', `num_grays', `pixel_mode', and `palette_mode' unsigned types. * src/base/ftbitmap.c: Updated. (FT_Bitmap_Copy): Fix casts. * src/cache/ftcsbits.c, src/raster/ftraster.c, src/sfnt/pngshim.c: Updated. 2014-11-19 Werner Lemberg <wl@gnu.org> Make `FT_Bitmap_Convert' correctly handle negative `pitch' values. * src/base/ftbitmap.c (FT_Bitmap_Convert): Always use positive value for the pitch while copying data. Correctly set pitch sign in target bitmap. 2014-11-19 Werner Lemberg <wl@gnu.org> Minor code improvement in `FT_Bitmap_Embolden'. * src/base/ftbitmap.c (FT_Bitmap_Embolden) <FT_PIXEL_MODE_GRAY[24]>: Fix thinko. 2014-11-19 Alexei Podtelezhnikov <apodtele@gmail.com> * src/base/fttrigon.c: Use dedicated `FT_Angle' for arctan table. 2014-11-19 Behdad Esfahbod <behdad@behdad.org> Avoid compiler warnings on x86-64 for `FT_MulFix'. `FT_MulFix' takes `FT_Long' parameters as defined in `freetype.h', but several inline implementations of it in `ftcalc.h' take `FT_Int32' arguments. This is causing compiler warnings on x86-64: If parameters of type `FT_Fixed' (= `FT_Long') are passed to the inline implementation of this function, integer values are truncated from 64bit to 32bit. * include/internal/ftcalc.h (FT_MulFix) [FT_MULFIX_ASSEMBLER]: Add casts. 2014-11-15 Werner Lemberg <wl@gnu.org> [sfnt] Fix Savannah bug #43597. * src/sfnt/pngshim.c (Load_SBit_Png): Protect against too large bitmaps. 2014-11-12 Werner Lemberg <wl@gnu.org> [sfnt] Fix Savannah bug #43591. * src/sfnt/ttsbit.c (tt_sbit_decoder_init): Protect against addition and multiplication overflow. 2014-11-12 Werner Lemberg <wl@gnu.org> [sfnt] Fix Savannah bug #43590. * src/sfnt/ttload.c (check_table_dir, tt_face_load_font_dir): Protect against addition overflow. 2014-11-12 Werner Lemberg <wl@gnu.org> [sfnt] Fix Savannah bug #43589. * src/sfnt/sfobjs.c (woff_open_font): Protect against addition overflow. 2014-11-12 Werner Lemberg <wl@gnu.org> [sfnt] Fix Savannah bug #43588. * src/sfnt/ttcmap.c (tt_cmap8_validate, tt_cmap10_validate, tt_cmap12_validate, tt_cmap13_validate, tt_cmap14_validate): Protect against overflow in additions and multiplications. 2014-11-10 Alexei Podtelezhnikov <apodtele@gmail.com> [base] CORDIC improvements. The scaling between the hypotenuse and its CORDIC approximation is based on regression analysis. The smaller padding for `theta' is justified by its maximum error of less than 6. * src/base/fttrigon.c (ft_trig_downscale): Borrow code from ./ftcalc.c (ft_multo64), change linear intercept. (ft_trig_pseudo_polarize): Decrease `theta' padding. 2014-11-09 Werner Lemberg <wl@gnu.org> * src/base/ftstroke.c (ft_stroker_inside): Fix border intersections. One more place to check whether `radius' is zero. Problem reported by Marco Wertz <marco.wertz@gmx.de>. 2014-11-07 Werner Lemberg <wl@gnu.org> [bdf] Fix Savannah bug #43535. * src/bdf/bdflib.c (_bdf_strncmp): New macro that checks one character more than `strncmp'. s/ft_strncmp/_bdf_strncmp/ everywhere. 2014-11-06 Werner Lemberg <wl@gnu.org> [pcf] Fix Savannah bug #43548. * src/pcf/pcfread.c (pcf_get_encodings): Add sanity checks for row and column values. 2014-11-06 Werner Lemberg <wl@gnu.org> [pcf] Fix Savannah bug #43547. * src/pcf/pcfread.c (pcf_read_TOC): Check `size' and `offset' values. 2014-11-06 Werner Lemberg <wl@gnu.org> * src/pcf/pcfread.c (pcf_read_TOC): Avoid memory leak. 2014-11-03 Infinality <infinality@infinality.net> * src/truetype/ttsubpix.c (COMPATIBILITY_MODE_Rules): Updated. The previous commit deteriorates rendering of DejaVu and similar fonts; this gets compensated with this rule. 2014-11-03 Werner Lemberg <wl@gnu.org> * src/truetype/ttinterp.c (Ins_DELTAP): Fix subpixel hinting. Before this patch, it was impossible to ever call DELTAP[123] in subpixel hinting mode as described in the ClearType whitepaper; it only worked if in `compatibility mode'. However, compatibility mode essentially disables SHPIX, completely ruining hinting of ttfautohint output, for example. We now follow the whitepaper more closely so that DELTAP[123] instructions for touched points in the non-subpixel direction are executed. 2014-10-31 Alexei Podtelezhnikov <apodtele@gmail.com> [smooth] Improve code readability. * src/smooth/ftsmooth.c (ft_smooth_render_generic): Rearrange code. 2014-10-31 Alexei Podtelezhnikov <apodtele@gmail.com> [smooth] Reduce outline translations during rendering. * src/smooth/ftsmooth.c (ft_smooth_render_generic): Translate origin virtually by modifying cbox, actually translate outline if cumulative shift is not zero. 2014-10-30 Alexei Podtelezhnikov <apodtele@gmail.com> [smooth] Fix Savannah bug #35604 (cont'd). * src/smooth/ftsmooth.c (ft_smooth_render_generic): Remove checks and casts that became unnecessary after the variable type upgrades. 2014-10-29 Alexei Podtelezhnikov <apodtele@gmail.com> [smooth] Improve code readability. * src/smooth/ftsmooth.c (ft_smooth_render_generic): Rearrange code. 2014-10-29 Alexei Podtelezhnikov <apodtele@gmail.com> Unify hypotenuse approximations. * include/internal/ftcalc.h (FT_HYPOT): Move macro from here... * include/internal/ftobjs.h: ... to here, next to required `FT_ABS'. * src/smooth/ftgrays.c (gray_render_cubic): Use it here. 2014-10-25 Werner Lemberg <wl@gnu.org> [cff] Test valid darkening parameter macros in `ftoption.h'. We no longer need an otherwise unused typedef that can cause a gcc warning. Problem reported by Alexei. * src/cff/cffobjs.c (cff_driver_init): Use `CFF_CONFIG_OPTION_DARKENING_PARAMETER_XXX' macros directly. (SET_DARKENING_PARAMETERS): Removed. Compile time tests are now ... * devel/ftoption.h, include/config/ftoption.h: ... here. 2014-10-25 Alexei Podtelezhnikov <apodtele@gmail.com> Improve flat corner definition. * include/internal/ftcalc.h (FT_HYPOT): Macro to approximate Euclidean distance with the alpha max plus beta min algorithm. * src/base/ftcalc.c (ft_corner_is_flat): Use it instead of Taxicab metric. 2014-10-23 David Weiß <David.Weiss@ptvgroup.com> [build] Improve property file for vc2010. User-defined properties should be empty by default to prevent linker failures. * builds/windows/vc2010/freetype.user.props, builds/windows/vc2010/freetype.vcxproj: s/OptionsDirectory/UserOptionDirectory/. Comment out all user options. 2014-10-23 Werner Lemberg <wl@gnu.org> [cff] Work around bug in preprocessor of MSVC 2010. We have been hit by https://connect.microsoft.com/VisualStudio/feedback/details/718976/msvc-pr * devel/ftoption.h, include/config/ftoption.h: Replace `CFF_CONFIG_OPTION_DARKENING_PARAMETERS' with eight macros `CFF_CONFIG_OPTION_DARKENING_PARAMETER_{X,Y}{1,2,3,4}'. * src/cff/cffobjs.c (SET_DARKENING_PARAMETERS): Removed. We no longer need double expansion. (SET_DARKENING_PARAMETERS_0): Renamed to ... (SET_DARKENING_PARAMETERS): ... this. Update call. 2014-10-20 Werner Lemberg <wl@gnu.org> [sbit] Minor fixes. * src/sfnt/ttsbit.c (tt_face_load_sbit) [TT_SBIT_TABLE_TYPE_SBIX]: Accept overlay format also, but emit warning message in that case. (tt_sbit_decoder_load_metrics): Add missing newline to error message. (tt_sbit_load_sbix_image): Add `rgbl' graphic type (as used on iOS 7.1) to the list of unsupported formats. 2014-10-19 Alexei Podtelezhnikov <apodtele@gmail.com> [truetype] Clean up bytecode rounding. Zero distance does not have to be treated specially if you follow specifications and check the sign as the very last step of rounding. * src/truetype/ttinterp.c (Round_None, Round_To_Grid, Round_Down_To_Grid, Round_Up_To_Grid, Round_To_Double_Grid): Use macros when available, do not check for non-zero distance.

This essentially moves the Telugu script from the `Indic' hinter to the `Latin' hinter. Note that this is a first shot and quite certainly needs refinements. * src/autofit/afblue.dat: Add blue zone data for Telugu. * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated. * src/autofit/afscript.h: Add Telugu standard characters and move data out of AF_CONFIG_OPTION_INDIC block. * src/autofit/afranges.c: Move Telugu data out of AF_CONFIG_OPTION_INDIC block. * src/autofit/afstyles.h: Update Telugu data; in particular, use AF_WRITING_SYSTEM_LATIN. 2014-10-18 David Wimsey <david@wimsey.us> [cmake] Add iOS build support. From Savannah patch #8497. * builds/cmake/iOS.cmake: New file. Universal binaries are built with both 32 and 64 bit arm architectures. * CMakeLists.txt (IOS_PLATFORM): New variable for running the iOS toolchain.

The adaptation of the cjk auto-hinter module to blue stringsets in 2013-08-25 had three severe bugs. Mea culpa. 1. Contrary to the latin auto-hinter, characters for reference and overshoot values of a blue zone are specified separately. Due to the screwed-up change it didn't work at all. 2. A boolean comparison was erroneously replaced with a cast, causing invalid results with the `^' operator later on. The visual artifact caused by this problem is the topic of the bug report. 3. Two flag values were inverted, causing incorrect assignment of reference and overshoot values. * src/autofit/afblue.dat: Fix CJK bluestrings, introducing a new syntax to have both reference and overshoot characters in a single string. This is error #1. Add extensive comments. * src/autofit/afblue.hin (AF_BLUE_PROPERTY_CJK_FILL): Removed, no longer used. (AF_BLUE_PROPERTY_CJK_TOP, AF_BLUE_PROPERTY_CJK_HORIZ): Fix values. This is error #3. * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated. * src/autofit/afcjk.c (af_cjk_metrics_init_blues): Correct error #1. Use character `|' to separate characters for reference and overshoot values. Improve tracing messages, synchronizing them with the latin auto-hinter. (af_cjk_hints_compute_blue_edges): Fix value of `is_top_right_blue'. This is error #2. (af_cjk_align_linked_edge): Add tracing message. * src/autofit/afcjk.h (AF_CJK_IS_FILLED_BLUE): Removed, no longer used. 2014-04-17 Werner Lemberg <wl@gnu.org> [autofit] More coverage fixes for complex scripts. * src/autofit/hbshim.c (af_get_coverage): Merge input glyph coverage of GSUB lookups into output coverage.

Ignore whitespace in strings. 2014-04-14 Werner Lemberg <wl@gnu.org> [autofit] Improve coverage handling. * src/autofit/hbshim.c (af_get_coverage): Don't exclude glyphs appearing in the GPOS table if we are processing the default coverage. 2014-04-13 David Weber <weber.aulendorf@googlemail.com> [smooth] Fix stand-alone compilation. * src/smooth/ftgrays.c (FT_BEGIN_STMNT, FT_END_STMNT): Define. 2014-04-12 Werner Lemberg <wl@gnu.org> [autofit] Redesign the recognition algorithm of strong points. In particular, local extrema without horizontal or vertical segments are better recognized: + A + D \ / \ / \ / \ / \ + C \ / B +/ If the distances AB and CD are large, point B wasn't previously detected as an extremum since the `ft_corner_is_flat' function `swallowed' BC regardless of its direction, tagging point B as weak. The next iteration started at B and made `ft_corner_is_flat' swallow point C, tagging it as weak also, et voilà. To improve that, another pass gets now performed before calling `ft_corner_is_flat' to improve the `topology' of an outline: A sequence of non-horizontal or non-vertical vectors that point into the same quadrant are handled as a single, large vector. Additionally, distances of near points are now accumulated, which makes the auto-hinter handle them as if they were prepended to the next non-near vector. This generally improves the auto-hinter's rendering results. * src/autofit/afhints.c (af_glyph_hints_reload): Implement it. * src/autofit/afhints.h (AF_FLAGS): Remove no longer used flag `AF_FLAG_NEAR'. 2014-04-05 Werner Lemberg <wl@gnu.org> [autofit] Improve scoring algorithm for identifying stems. Problem reported by Karsten Lücke <karsten.luecke@kltf.de>. The new algorithm takes care of the width of stems: If the distance between two segments is larger than the largest stem width, the demerits quickly increase for larger distances. This improves hinting of slanted fonts (especially if the inner parts of serifs have non-horizontal `shoulders'), avoiding false stem links. * src/autofit/aflatin.c (af_latin_hints_link_segments): Use largest stem width (if available) to compute better demerits for distances between stems. (af_latin_hints_detect_features): Pass stem width array and array size. (af_latin_metrics_init_widths): Updated to use original algorithm. (af_latin_hints_apply): Updated to use new algorithm. * src/autofit/aflatin.h: Updated. * src/autofit/afcjk.c: Updated. 2014-04-03 Werner Lemberg <wl@gnu.org> Don't require `gzip' module for `sfnt'.

The data itself gets then parsed line by line, simply increasing the current pointer into the buffer; if the search for the final newline character exceeds the buffer size, more data gets read. However, in case the current line's end is very near to the buffer end, and the keyword to compare with is longer than the current line's length, an out-of-bounds read might happen since `memcmp' doesn't stop properly at the string end. * src/bdf/bdflib.c: s/ft_memcmp/ft_strncmp/ to make comparisons stop at string ends. 2014-02-17 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> [autofit] Fix `make multi' compilation. * src/autofit/hbshim.c: Include `afglobal.h' and `aftypes.h'. 2014-02-19 Werner Lemberg <wl@gnu.org> Simon Bünzli <zeniko@gmail.com> Fix Savannah bug #32902.

Split the single, incorrect Indic entry into separate scripts so that the covered ranges are the same: Bengali, Devanagari, Gujarati, Gurmukhi, Kannada, Limbu, Malayalam, Oriya, Sinhala, Sundanese, Syloti Nagri, Tamil, Telugu, and Tibetan. At the same time, remove entries for Meetei Mayek and Sharada – the Unicode ranges were incorrect (and nobody has complained about that), fonts are scarce for those scripts, and the Indic auto-hinter support is rudimentary anyways. * src/autofit/afscript.h: Updated, using AF_CONFIG_OPTION_INDIC and AF_CONFIG_OPTION_CJK. * src/autofit/afstyles.h (STYLE_DEFAULT_INDIC): New auxiliary macro.

Combining them, as originally envisioned, would lead to much more complicated code, as investigations have shown meanwhile. The major drawback is that we run out of available style slots much earlier. However, this is only a theoretical issue since we don't support a large number of scripts currently. * src/autofit/afcover.h: Replace `COVERAGE_{1,2,3}' macros with a single-element `COVERAGE' macro, sort the elements by the feature tags, and add entry for `ruby'. * src/autofit/aftypes.h: Updated. * src/autofit/hbshim.c: Updated. 2013-12-28 Werner Lemberg <wl@gnu.org> [autofit] Code shuffling to reduce use of cpp macros. * src/autofit/afglobal.c (af_face_globals_compute_style_coverage): Call `af_get_coverage' unconditionally. * src/autofit/autofit.c: Include `hbshim.c' unconditionally. * src/autofit/hbshim.c (af_get_coverage) [!FT_CONFIG_OPTION_USE_HARFBUZZ]: Provide dummy function. * src/autofit/hbshim.h: Provide function declarations unconditionally. 2013-12-28 Werner Lemberg <wl@gnu.org> [autofit] Add wrapper function for `FT_Get_Char_Index'.

The fragmented resources in Suitcase and .dfont should be reordered when `POST' resource for Type1 is being restored, but reordering of sfnt resources induces the different face order.

Coverages are the interface to the HarfBuzz library to access OpenType features for handling glyphs not addressable by the cmap. Right now, compilation of HarfBuzz is only added to the development build. A solution for standard build mode will be delayed until HarfBuzz gets split into two libraries to avoid mutual dependencies between FreeType and HarfBuzz. Note that this is only a first step in handling coverages, basically providing the framework only.

This large patch changes the header file directory layout from `include/freetype/...' to `include/...', effectively removing one level. Since the file `ft2build.h' is also located in `include' (and it stays there even after installation), all FreeType header files are now in a single directory. Applications that use (a) `freetype-config' or FreeType's `pkg-config' file to get the include directory for the compiler, and (b) the documented way for header inclusion like #include <ft2build.h> #include FT_FREETYPE_H ... don't need any change to the source code. * include/freetype/*: Move up to... * include/*: ... this directory. * builds/amiga/include/freetype/*: Move up to... * builds/amiga/include/*: ... this directory. */*: Essentially do `s@/freetype/@/@' where appropriate. * CMakeLists.txt: Simplify. * builds/unix/freetype-config.in, builds/unix/freetype2.in: For `--cflags', return a single directory. * builds/unix/install.mk (install): No longer try to remove `cache' and `internal' subdirectories; instead, remove the `freetype' subdirectory. 2013-11-12 Werner Lemberg <wl@gnu.org> [truetype] Fix last `truetype' commit. * src/truetype/ttgload.c (tt_get_metrics): Preserve stream position.

Two benefits: The allocated FDEF (and IDEF) array gets slightly smaller, and the `ttdebug' demo program has access to function numbers without additional costs. Fortunately, no changes to FontForge are necessary – this is the only external TrueType debugger I know of, but others may exist and should check the code accordingly. * src/truetype/ttinterp.h (TT_CallRec): Replace `Cur_Restart' and `Cur_End' with a pointer to the corresponding `TT_DefRecord' structure. * src/truetype/ttinterp.c (DO_JROT, DO_JMPR, DO_JROF, Ins_ENDF, Ins_CALL, Ins_LOOPCALL, Ins_UNKNOWN, TT_RunIns <Invalid_Opcode>): Updated. 2013-10-27 Werner Lemberg <wl@gnu.org> [sfnt] Implement support for `OS/2' table version 5.

When using `ADD' with an immediate operand, the instruction is actually `ADD Rd, Rn, #<imm12>', that is, the maximum of the immediate operand cannot exceed 4095. It will fail to compile with LLVM. However, in GCC, due to some legacy compatibility considerations, `ADD.W' will be automatically emitted when the immediate operand is larger than 4095. * builds/unix/ftconfig.in, include/freetype/config/ftconfig.h (FT_MulFix_arm) [__GNUC__]: Support clang compiler. * src/truetype/ttinterp.c (TT_MulFix14_arm) [__GNUC__]: Ditto. 2013-10-12 Werner Lemberg <wl@gnu.org> [autofit] Improve tracing of `latin' hinter. * src/autofit/aflatin.c (af_latin_metrics_init_blues): Report blue zone types. (af_latin_metrics_scale_dim): Report scaling changes due to x height alignment. Report scaled stroke width and blue zone values. 2013-10-03 Dave Arnold <darnold@adobe.com> * src/cff/cf2font.c (cf2_computeDarkening): Avoid division by zero. Note that the old code avoided using a region of the piecewise linear function where the slope was zero. The recovery was to use a different section of the function, which produced a different, incorrect amount of darkening. 2013-10-02 Darrell Bellert <darrell.bellert@hl.konicaminolta.us> * src/sfnt/ttload.c (tt_face_load_pclt): Fix `pclt_fields'. 2013-10-02 Dave Arnold <darnold@adobe.com> * src/cff/cf2font.c (cf2_computeDarkening): Initialize darkenAmount. This line was lost in commit 89ca1fd6 (from 2013-06-25). The effect is to use a previous darkening amount when producing an unhinted, unscaled outline. This can cause autohint samples in ftgrid and ftview to be based on darkened CFF outlines instead of unhinted, undarkened ones. 2013-09-29 Dave Arnold <darnold@adobe.com> Fix Savannah bug #39295. The bug was caused by switching to the initial hintmap (the one in effect when `moveto' executes) just before drawing the final element in the charstring. This ensured that the path was closed (in both Character Space and Device Space). But if the final element was a curve and if the final hintmap was different enough from the initial one, then the curve was visibly distorted. The first part of the fix is to draw the final curve using the final hintmap as specified by the charstring. This corrects the distortion but does not ensure closing in Device Space. It may require the rasterizer to automatically generate an extra closing line. Depending on the hintmap differences, this line could be from zero to a couple pixels in length. The second part of the fix covers the case where the charstring subpath is closed with an explicit line. We now modify that line's end point to avoid the distortion. Some glyphs in the bug report font (TexGyreHeros-Regular) that show the change are: 25ppem S (98) 24ppem eight (52) 25.5ppem p (85) Curves at the *end* of a subpath are no longer distorted. However, some of these glyphs have bad hint substitutions in the middle of a subpath, and these are not affected. The patch has been tested with a set of 106 fonts that shipped with Adobe Creative Suite 4, together with 756 Open Source CFF fonts from Google Fonts. There are 1.5 million glyphs, of which some 20k are changed with the fix. A sampling of a few hundred of these changes have been examined more closely, and the changes look good (or at least acceptable). * src/cff/cf2hints.h (CF2_GlyphPathRec): New element `pathIsClosing' to indicate that we synthesize a closepath line. * src/cff/cf2hints.c (cf2_glyphpath_init): Updated. (cf2_glyphpath_pushPrevElem): If closing, use first hint map (for `lineto' operator) and adjust hint zone. For synthesized closing lines, use end point in first hint zone. (cf2_glyphpath_lineTo): Take care of synthesized closing lines. In particular, shift the detection of zero-length lines from character space to device space. (cf2_glyphpath_closeOpenPath): Remove assertion. Updated. 2013-09-25 Werner Lemberg <wl@gnu.org> * src/autofit/aflatin.c (af_{grek,cyrl}_uniranges): Fix arrays. 2013-09-25 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> [bdf, pcf] Refuse non-zero face_index.

This change introduces a new blue zone property `AF_BLUE_PROPERTY_LATIN_LONG' to make the auto-hinter ignore short top segments. * src/autofit/afblue.dat: Fix Hebrew blue strings. Use AF_BLUE_PROPERTY_LATIN_LONG for AF_BLUE_STRING_HEBREW_TOP. * src/autofit/afblue.hin (AF_BLUE_PROPERTY_LATIN_LONG): New macro. * src/autofit/afblue.c, src/autofit/afblue.h: Updated. * src/autofit/aflatin.c (af_latin_metrics_init_blues): Handle `AF_LATIN_IS_LONG_BLUE'. * src/autofit/aflatin.h (AF_LATIN_IS_LONG_BLUE): New macro. 2013-08-28 Behdad Esfahbod <behdad@google.com> [sfnt] Fix frame access while reading WOFF table directory. * src/sfnt/sfobjs.c (woff_open_font): Using single memory frame while reading the directory entries for the whole loop. 2013-08-29 Werner Lemberg <wl@gnu.org> Behdad Esfahbod <behdad@google.com> Implement support for WOFF containers. We simply synthesize a SFNT from the WOFF, create a memory stream for the new data, and load the SFNT as usual. Does NOT add any API to access WOFF metadata or private blocks. * include/freetype/internal/tttypes.h (WOFF_HeaderRec, WOFF_TableRec): New structures. * include/freetype/tttags.h (TTAG_wOFF): New macro. * src/base/ftobjs.c (FT_Open_Face): Set `stream' after calling `open_face'. * src/sfnt/sfobjs.c [FT_CONFIG_OPTION_SYSTEM_ZLIB]: Include `FT_GZIP_H'.

Update callers. 2013-08-28 Werner Lemberg <wl@gnu.org> [gzip] New function `FT_Gzip_Uncompress'. This is modeled after zlib's `uncompress' function. We need this for WOFF support. * include/freetype/ftgzip.h, src/gzip/ftgzip.c (FT_Gzip_Uncompress): New function. * src/gzip/rules.mk: Rewrite to better reflect dependencies. 2013-08-28 Werner Lemberg <wl@gnu.org> [autofit] Fix `make multi' compilation. * src/autofit/afblue.cin, src/autofit/afblue.c: Don't include `afblue.h' but `aftypes.h'. * src/autofit/afcjk.c: Don't include `aftypes.h' but `afglobal.h'. 2013-08-28 Werner Lemberg <wl@gnu.org> [autofit] Fix C++ compilation. * src/autofit/afglobal.c (af_face_globals_get_metrics), src/autofit/afdummy.c (af_dflt_script_class), src/autofit/afindic.c (af_deva_script_class): Use proper casts. 2013-08-27 Behdad Esfahbod <behdad@google.com> * src/sfnt/ttload.c (tt_face_load_font_dir): Fix sign typos. 2013-08-27 Behdad Esfahbod <behdad@google.com> FT_Open_Face: Improve external stream handling. If the font's `clazz->init_face' function wants to swap to new stream, handling of whether original stream was external could result to either memory leak or double free. Mark externality into face flags before calling `init_face' such that the clazz can handle external streams properly. * src/base/ftobjs.c (FT_Open_Face): Move code to set FT_FACE_FLAG_EXTERNAL_STREAM to... (open_face): This function. 2013-08-27 Werner Lemberg <wl@gnu.org> Remove `FT_SqrtFixed' function. It's no longer used. * include/freetype/internal/ftcalc.h, src/base/ftcalc.c: Do it. 2013-08-27 Werner Lemberg <wl@gnu.org> [autofit] While tracing, report script names instead of ID values. * src/autofit/afglobal.c (af_script_names) [FT_DEBUG_LEVEL_TRACE]: New array. * src/autofit/afglobal.h: Updated. * src/autofit/afcjk.c (af_cjk_metrics_init_widths, af_cjk_hint_edges): Use `af_script_names'. * src/autofit/aflatin.c (af_latin_metrics_init_widths, af_latin_hint_edges): Ditto. 2013-08-26 Werner Lemberg <wl@gnu.org> [autofit] Report used script while hinting a glyph. * src/autofit/afcjk.c (af_cjk_hint_edges), src/autofit/aflatin.c (af_latin_hint_edges): Implement it. 2013-08-26 Werner Lemberg <wl@gnu.org> [autofit] Add support for Hebrew script. * src/autofit/afblue.dat: Add blue strings for Hebrew. * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated. * src/autofit/aflatin.c (af_hebr_uniranges): New array.

(af_cjk_metrics_init_blues): Initialize `axis' outside of the inner loop. Improve tracing messages. (af_cjk_hint_edges) [FT_DEBUG_LEVEL_TRACE]: New variable `num_actions' to count hinting actions. Improve tracing messages. * src/autofit/aflatin.c (af_latin_metrics_init_widths): Mention script ID in tracing message. (af_latin_metrics_init_blues, af_latin_hint_edges): Improve tracing messages. 2013-08-26 Werner Lemberg <wl@gnu.org> Better tracing of loaded glyphs. Previously, the loading of a glyph was traced at level 4, if at all. With this change, all font loading routines emit a tracing message at level 1, making it easier to select tracing output (for example using F2_DEBUG="any:1 afhints:7 aflatin:7"). * src/bdf/bdfdrivr.c (BDF_Glyph_Load): Add tracing message. * src/cff/cffdrivr.c (cff_glyph_load): Ditto. * src/cff/cffgload.c (cff_decoder_prepare): Improve tracing messages. * src/cid/cidgload.c (cid_load_glyph): Use level 1 for tracing message. * src/pcf/pcfdrivr.c (PCF_Glyph_Load): Ditto. * src/pfr/pfrobjs.c (pfr_slot_load): Add tracing message. * src/truetype/ttgload.c (TT_Load_Glyph): Ditto. * src/type1/t1gload.c (T1_Load_Glyph): Ditto. * src/type42/t42objs.c (T42_GlyphSlot_Load): Ditto. * src/winfonts/winfnt.c (FNT_Load_Glyph): Ditto. 2013-08-26 Werner Lemberg <wl@gnu.org> [autofit] Fix script selection. * src/autofit/afglobal.c (af_face_globals_get_metrics): Use `AF_SCRIPT_DFLT', not value 0. Simplify code. * src/autofit/afscript.h: Sort by script name. 2013-08-26 Werner Lemberg <wl@gnu.org> [autofit] Make `dummy' hinter work as expected. * src/autofit/afdummy.c (af_dummy_hints_init): Properly set scaling information.

(af_cjk_hani_blue_chars): Removed. (AF_CJK_BLUE_TYPE_*): Removed. (af_cjk_metrics_init_blues): Replace AF_CJK_MAX_TEST_CHARACTERS with AF_BLUE_STRING_MAX_LEN. Change loops to use offsets (in file `afblue.h') into the new arrays `af_blue_stringsets' and `af_blue_strings' (in file `afblue.c'). Instead of three dimensions (as used in the old blue string array) we now use properties to do the same, saving one loop nesting level. * src/autofit/afcjk.h: Remove old enumeration values superseded by the new data in `afblue.h'. (AF_CJK_IS_TOP_BLUE, AF_CJK_IS_HORIZ_BLUE, AF_CJK_IS_FILLED_BLUE, AF_CJK_IS_RIGHT_BLUE): New macros, to be used in `af_cjk_metrics_init_blues'. (AF_CJK_BLUE_IS_RIGHT): Remove this now redundant enum value. (AF_CJK_BLUE_IS_TOP): Renamed to... (AF_CJK_BLUE_TOP): This. (AF_CJK_MAX_BLUES): Remove. (AF_CJKAxisRec): Updated. 2013-08-25 Werner Lemberg <wl@gnu.org> [autofit] Typo. * src/autofit/afblue.hin, src/autofit/afblue.c (GET_UTF8_CHAR): Use cast. 2013-08-25 Werner Lemberg <wl@gnu.org> [autofit] Synchronize `cjk' with `latin' module (and vice versa). * src/autofit/afcjk.c (af_cjk_metrics_init_widths): Add tracing messages. (af_cjk_metrics_init_blues): Don't pass blue string array as argument but use the global array directly. Use `outline' directly. Update and add tracing messages. (af_cjk_metrics_init): Simplify code. (af_cjk_metrics_scale_dim): Improve tracing message. (af_cjk_metrics_scale): Synchronize. * src/autofit/aflatin.c (af_latin_metrics_init_widths, af_latin_metrics_init_blues): Improve and add tracing messages. 2013-08-25 Werner Lemberg <wl@gnu.org> [autofit] Make `latin' module use blue stringsets. * src/autofit/aflatin.c (AF_LATIN_MAX_TEST_CHARACTERS): Removed. (af_latin_blue_chars): Removed. (af_latin_metrics_init_blues): Replace AF_LATIN_MAX_TEST_CHARACTERS with AF_BLUE_STRING_MAX_LEN. Change loops to use offsets (in file `afblue.h') into the new arrays `af_blue_stringsets' and `af_blue_strings' (in file `afblue.c'). Use `AF_LATIN_IS_SMALL_TOP_BLUE' macro. * src/autofit/aflatin.h: Remove old enumeration values superseded by the new data in `afblue.h'. (AF_LATIN_IS_TOP_BLUE): Updated definition. (AF_LATIN_IS_SMALL_TOP_BLUE): New macro. (AF_LATIN_MAX_BLUES): Remove. (AF_LatinAxisRec): Updated. 2013-08-25 Werner Lemberg <wl@gnu.org> [autofit] Add blue stringsets. * src/autofit/aftypes.h: Include `afblue.h'. (AF_ScriptClassRec): Add `blue_stringset' field.

The idea is to have a central file which gets processed by a Perl script to create proper `.c' and `.h' files using templates. There are two other reasons to do that: . The data file should be easily readable. We use UTF-8 encoding which then gets converted to single bytes. . Since the number of supported scripts will increase soon, the current usage of blue string arrays is a waste of space. Using the Perl script it is possible to imitate jagged arrays, defining enumeration constants as offsets into the arrays. This commit only adds files without changing any functionality. * src/autofit/afblue.dat: New data file. * src/tools/afblue.pl: New Perl script for processing `afblue.dat'. * src/autofit/afblue.cin, src/autofit/afblue.hin: New template files for... * src/autofit/afblue.c, src/autofit/afblue.c: New source files. To avoid a dependency on Perl, we add them too. 2013-08-19 Alexei Podtelezhnikov <apodtele@gmail.com> [base] Enable new algorithm for `BBox_Cubic_Check'. * src/base/ftbbox.c: Enable new BBox_Cubic_Check algorithm, remove the old one. Improve comments. 2013-08-18 Werner Lemberg <wl@gnu.org> * builds/unix/unix-def.in (freetype2.pc): Don't set executable bit. 2013-08-18 Werner Lemberg <wl@gnu.org> Fix Savannah bug #39804. * builds/unix/configure.raw (LIBPNG): Define and export. * builds/unix/freetype-config.in, builds/unix/freetype2.in: Handle libpng. 2013-08-17 Alexei Podtelezhnikov <apodtele@gmail.com> [base] Clean up BBox_Conic_Check. * src/base/ftbbox.c (BBox_Conic_Check): Remove redundant checks for extremum at the segment ends, which are already within the bbox. Slightly modify calculations. 2013-08-15 Alexei Podtelezhnikov <apodtele@gmail.com> [base] Finish experimental (disabled) BBox_Cubic_Check implementation. * src/base/ftbbox.c (BBox_Cubic_Check): Scale arguments to improve accuracy and avoid overflows. 2013-08-13 Alexei Podtelezhnikov <apodtele@gmail.com> [base] Refactor experimental (disabled) BBox_Cubic_Check. * src/base/ftbbox.c (BBox_Cubic_Check): Implement the minimum search as the mirror image of the maximum search implemented here... (update_max): New function. 2013-08-06 John Tytgat <John.Tytgat@esko.com> Fix Savannah bug #39702. * src/cff/cffload.c (cff_index_get_pointers): Check for `cur_offset != 0'; this stronger test is mandated by the CFF specification. Fix test for INDEX structures which have one or more empty entries at the end. 2013-08-05 Werner Lemberg <wl@gnu.org> Fix gcc pragmas, part 2. * src/truetype/ttinterp.c (TT_MulFix14_long_long, TT_DotFix14_long_long): `#pragma gcc diagnostic {push,pop}' has been introduced with gcc version 4.6. 2013-08-05 Werner Lemberg <wl@gnu.org> Fix gcc pragmas. * src/truetype/ttinterp.c (TT_MulFix14_long_long, TT_DotFix14_long_long): Older gcc versions don't accept diagnostic pragmas within a function body. 2013-08-05 Werner Lemberg <wl@gnu.org> Fix Savannah bug #39700. * builds/unix/ftconfig.h: Synchronize with `include/freetype/config/ftconfig.h'. * builds/vms/ftconfig.h: Ditto. Make the differences to the master `ftconfig.h' file as small as possible for easier maintenance. 2013-08-05 Werner Lemberg <wl@gnu.org> [autofit] Improve handling of `near' points. Points which are very near to each other are now marked as such. The `weak' flag is then computed by using the `in' vector of the first and the `out' vector of the last point of a group of near points. For example, this fixes the rendering of glyph `Oslash' in `Roboto-Thin.ttf'. * src/autofit/afhints.h (AF_Flags): New value `AF_FLAGS_NEAR'. * src/autofit/afhints.c (af_glyph_hints_reload): Introduce the heuristic value `near_limit' to decide whether the current point is near to the previous one, then set `AF_FLAG_NEAR' accordingly. Store good `in' vector (of last non-near point) in `last_good_in_{x,y}' and use it as an argument to `ft_corner_is_flat' if necessary. 2013-08-02 Werner Lemberg <wl@gnu.org> * include/freetype/ftcffdrv.h: Improve documentation. This is based on blog entries from David Lemon and Dave Arnold (both from Adobe) with kind permission. Dave also helped in proof-reading. 2013-08-02 Werner Lemberg <wl@gnu.org> [autofit] Move declaration of scripts into separate file. This has the benefit that we don't need to duplicate the data at different places. * src/autofit/afscript.h: New file. * src/autofit/aftypes.h (AF_Script): Include `afscript.h' to define the enumeration values. * src/autofit/afglobal.c: Include `afscript.h' to get the script specific header files. (af_script_classes): Include `afscript.h' to fill this array. * src/autofit/afpic.c: Include `afscript.h' to get the script specific header files. (autofit_module_class_pic_init): Include `afscript.h' for initialization. * src/autofit/afpic.h (AF_SCRIPT_CLASSES_COUNT, AF_SCRIPT_CLASSES_REC_COUNT): Removed. Use `AF_SCRIPT_MAX' instead. * src/autofit/rules.mk (AUTOF_DRV_H): Updated. 2013-08-02 Werner Lemberg <wl@gnu.org> [autofit] Move declaration of writing systems into separate file. This has the benefit that we don't need to duplicate the data at different places. * src/autofit/afwrtsys.h: New file. * src/autofit/aftypes.h (AF_WritingSystem): Include `afwrtsys.h' to define the enumeration values. * src/autofit/afglobal.c: Include `afwrtsys.h' to get the writing system specific header files. Include `afpic.h'. (af_writing_system_classes): Include `afwrtsys.h' to fill this array. * src/autofit/afpic.c: Include `afwrtsys.h' to get the writing system specific header files.

Note that cppcheck still can't handle `#include FOO' (with `FOO' a macro). */* Improve variable scopes. */* Remove redundant initializations which get overwritten. * src/gxvalid/*: Comment out redundant code or guard it with FT_DEBUG_LEVEL_TRACE. 2013-07-30 Werner Lemberg <wl@gnu.org> [autofit] Introduce `writing systems'. This patch adds a new top level to the auto-hinter's script class hierarchy. It defines `writing systems' which can contain multiple scripts. For example, the `latin' writing system (in file `aflatin.c') is able to support scripts like Latin, Cyrillic, Armenian, etc., which can be handled similarly. Scripts are now named using four-letter OpenType tags. * src/autofit/aftypes.h (AF_ScriptClassRec): Move relevant members to... (AF_WritingSystemClassRec): This new structure.

The old code (essentially unchanged since the very beginning) incorrectly handled this configuration x -o- x / \ / \ / \ o o as flat and this o o / / x| x| | | o---------------o as round. (`o' and `x' are on and off points, respectively). This is a major change which should improve the rendering results enormously for many TrueType fonts, especially in the range approx. 20-40ppem, fixing the appearance of many overshoots. * src/autofit/aflatin.c (af_latin_metrics_init_blues): Look at the first and last points of the segment, not the points right before and after. 2013-07-19 Behdad Esfahbod <behdad@google.com> [sfnt] `sbix' fix-ups. * src/sfnt/sfobjs.c (sfnt_load_face): Apple's `sbix' color bitmaps are rendered scaled and then the `glyf' outline rendered on top.

When building for ARMv7 with thumb2 instructions, the optimized `FT_MulFix_arm' assembly routine was not being used. The reason for this is in the `ftconfig.h' header, namely: - The assembly routine uses the `smull' instruction which is not available when generating Thumb-1 machine code. It is available in Thumb-2 mode, though. - The header was written a long time ago before Thumb-2 became widely popular (e.g. with Android). So it simply doesn't use the assembly routine if the `__thumb__' built-in macro is defined. - When compiling in Thumb-2 mode, the compiler will define both `__thumb__' and `__thumb2__'. By checking for `(__thumb2__ || !__thumb__)', we ensure that the assembly routine is only avoided when generating Thumb-1 code. Given that this is performance-sensitive function, this improves `ftbench' as follows on a Galaxy Nexus: Before (us/op) After (us/op) - loading Arial.ttf glyphs at 14 ppem [1] Load 34.285 33.098 - same operation with the light auto-hinter [2] Load 31.317 29.590 - same operation without hinting [3] Load 6.143 5.376 - loading Arial.ttf advances at 14 ppem [4] Load_Advances (normal) 34.216 33.016 Load_Advances (fast) 0.176 0.176 [1] ftbench -t 5 -p -s 14 -b a -f 0008 Arial.ttf [2] ftbench -t 5 -p -s 14 -b a -r 1 -f 0028 Arial.ttf [3] ftbench -t 5 -p -s 14 -b a -f 000a Arial.ttf [4] ftbench -t 5 -p -s 14 -b b -f 0008 Arial.ttf * builds/unix/ftconfig.in, include/freetype/config/ftconfig.h (FT_MULFIX_ASSEMBLER): Fix handling for ARMv7. 2013-06-28 Werner Lemberg <wl@gnu.org> * docs/CHANGES: Updated. 2013-06-27 Werner Lemberg <wl@gnu.org> * src/winfonts/winfnt.c (FNT_Load_Glyph): Fix bitmap width guard. 2013-06-25 Werner Lemberg <wl@gnu.org> [cff] Add darkening limit to `darkening-parameters'. * src/cff/cffdrivr.c (cff_property_set): Add check. 2013-06-25 Werner Lemberg <wl@gnu.org> [cff] Add `darkening-parameters' property. * include/freetype/ftcffdrv.h: Document it. * src/cff/cffdrivr.c (cff_property_set, cff_property_get): Handle `darkening-parameters' property. * src/cff/cf2font.h (CF2_FontRec): Add `darkenParams' array. * src/cff/cf2font.c (cf2_computeDarkening): Add `darkenParams' argument and use it.

Recognizing properties follows in another commit. * devel/ftoption.h, include/freetype/config/ftoption.h (FT_CONFIG_OPTION_ENVIRONMENT_PROPERTIES): New macro. * include/freetype/config/ftstdlib.h (ft_getenv): New macro. * src/base/ftinit.c (ft_set_default_properties): New function to parse `FREETYPE_PROPERTIES' and calling `ft_property_string_set'. (FT_Init_FreeType): Updated. 2016-07-09 Werner Lemberg <wl@gnu.org> Add function `ft_property_string_set'. This is a preparation for handling an `FREETYPE_PROPERTIES' environment variable to control (some) driver properties. No change in functionality. * src/base/ftobjs.c (ft_property_do): Add `value_is_string' parameter. (ft_property_string_set): New function.

They were incorrect since the migration of the header files, on 2015-06-22. Either inexisting include/cache (removed on 2006-03-20) is not needed to be listed explicitly. Now ftmac.h is scanned only in the case of Mac OS & Mac OS X. 2016-07-08 Alexei Podtelezhnikov <apodtele@gmail.com> [smooth] Sub-banding protocol revision. Rasterization sub-banding is utilized at large sizes while using a rather small fixed memory pool. Indeed it is possible to make an educated guess how much memory is necessary at a given size for a given glyph. It turns out that, for a large majority of European glyphs, you should store about 8 times more boundary pixels than their height. Or, vice versa, if your memory pool can hold 800 pixels the band height should be 100 and you should sub-band anything larger than that. Should you still run out of memory, FreeType bisects the band but you have wasted some time. This is what has been implemented in FreeType since the beginning. It was overlooked, however, that the top band could grow to twice the default band size leading to unnecessary memory overflows there. This commit fixes that. Now the bands are distributed more evenly and cannot exceed the default size. Now the magic number 8 is really suitable for rather simple European scripts. For complex Chinese logograms the magic number should be 13 but that is subject for another day. * src/smooth/ftgrays.c (gray_convert_glyph): Revise sub-banding protocol. 2016-07-07 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> [mac] Fix Savannah bug #48417. Mac OS X linker throws errors when `-exported_symbol_list' input file includes non-existing symbols. Reported by Ryan Schmidt. * builds/exports.mk: Exclude ftmac.h from the headers for apinames by default. Include it when ftmac.c would be compiled. 2016-07-06 Werner Lemberg <wl@gnu.org> * src/truetype/ttinterp.c (TInstruction_Function): Removed, unused. 2016-07-05 Werner Lemberg <wl@gnu.org> * Version 2.6.4 released. ========================= Tag sources with `VER-2-6-4'. * docs/VERSION.TXT: Update documentation and bump version number to 2.6.4. * README, Jamfile (RefDoc), builds/windows/vc2005/freetype.vcproj, builds/windows/vc2005/index.html, builds/windows/vc2008/freetype.vcproj, builds/windows/vc2008/index.html, builds/windows/vc2010/freetype.vcxproj, builds/windows/vc2010/index.html, builds/windows/visualc/freetype.dsp, builds/windows/visualc/freetype.vcproj, builds/windows/visualc/index.html, builds/windows/visualce/freetype.dsp, builds/windows/visualce/freetype.vcproj, builds/windows/visualce/index.html, builds/wince/vc2005-ce/freetype.vcproj, builds/wince/vc2005-ce/index.html, builds/wince/vc2008-ce/freetype.vcproj, builds/wince/vc2008-ce/index.html: s/2.6.3/2.6.4/, s/263/264/. * include/freetype/freetype.h (FREETYPE_PATCH): Set to 4. * builds/unix/configure.raw (version_info): Set to 18:4:12. * CMakeLists.txt (VERSION_PATCH): Set to 4. * docs/CHANGES: Updated. 2016-07-05 Werner Lemberg <wl@gnu.org> * src/pfr/pfrsbit.c (pfr_lookup_bitmap_data): Fix compiler warning. 2016-07-04 Alexei Podtelezhnikov <apodtele@gmail.com> [smooth] Variable type revision (part 2). * src/smooth/ftgrays.c (TArea): Restore original definition as `int'. (gray_render_line) [FT_LONG64]: Updated. (gray_convert_glyph): 32-bit band bisection stack should be 32 bands. (gray_convert_glyph_inner): Trace successes and failures. 2016-07-04 Werner Lemberg <wl@gnu.org> [autofit] Handle single-point contours as segments. Doing so allows us to link them to edges – some fonts like `NotoSansGurmukhi-Regular' have such isolated points sitting exactly on other outlines. * src/autofit/aflatin.c (af_latin_hints_compute_segments): Don't ignore one-point contours but handle them specially as one-point segments. (af_latin_hints_compute_edges): Append one-point segments to edges if possible. 2016-07-02 Werner Lemberg <wl@gnu.org> [autofit] Remove unused structure members. * src/autofit/afhints.h (AF_SegmentRec, AF_EdgeRec): Remove `num_linked'. * src/autofit/afcjk.c (af_cjk_hints_link_segments): Updated. 2016-07-02 Werner Lemberg <wl@gnu.org> [autofit] Update to Unicode 9.0.0. * src/autofit/afranges.c (af_arab_nonbase_uniranges, af_cyrl_uniranges): Add new data. 2016-07-01 Alexei Podtelezhnikov <apodtele@gmail.com> [smooth] Variable type revision (part 1). This patch restores original `TCoord' definition as `int' so that the rendering pool is used more efficiently on LP64 platforms (unix). * src/smooth/ftgrays.c (gray_TWorker, TCell, gray_TBand): Switch some fields to `TCoord'. (gray_find_cell, gray_render_scanline, gray_render_line, gray_hline, gray_sweep, gray_convert_glyph): Updated. 2016-06-28 Alexei Podtelezhnikov <apodtele@gmail.com> [smooth] Minor clean-ups. * src/smooth/ftgrays.c (gray_TWorker): Remove redundant `ycount'. (gray_sweep, gray_convert_glyph, gray_dump_cells): Updated. 2016-06-27 Alexei Podtelezhnikov <apodtele@gmail.com> [smooth] Minor clean-ups. * src/smooth/ftgrays.c (gray_convert_glyph): Do not use volatile qualifier. (gray_raster_render): Move span initializations from here. (gray_sweep): ... to here and remove unused `target' argument. 2016-06-26 Alexei Podtelezhnikov <apodtele@gmail.com> [pcf] Fix handling of very large fonts (#47708). * src/pcf/pcfread.c (pcf_get_encodings): Make `encodingOffset' an unsigned short. Only reject `0xFFFF' as an invalid encoding offset. 2016-06-25 Werner Lemberg <wl@gnu.org> [truetype] Really fix deallocation in case of error (#47726). * src/truetype/ttgload.c (load_truetype_glyph): Thinko; initialize `outline.points' also. 2016-06-23 Alexei Podtelezhnikov <apodtele@gmail.com> [smooth] Consolidate memory management. * src/smooth/ftgrays.c (gray_init_cells): Remove function. (gray_TWorker): Remove fields that become local variables. (gray_raster_render): Move rendering buffer declaration from here. (gray_convert_glyph): ... to here and update accordingly. 2016-06-22 Alexei Podtelezhnikov <apodtele@gmail.com> [smooth] Consolidate boundary checks. Removing the checks from `gray_hline' shaves 1% off rendering speed. * src/smooth/ftgrays.c [STANDALONE_]: Duplicate `FT_MIN' and `FT_MAX'. (gray_TWorker): No need to store `clip_box'. (gray_hline): Remove unnecessary boundary checks. (gray_convert_glyph): Move boundary checks from here. (gray_raster_render): ... to here and consolidate. 2016-06-21 Alexei Podtelezhnikov <apodtele@gmail.com> [smooth] Use `FT_Outline_Get_CBox'. * src/smooth/ftgrays.c [STANDALONE_]: Duplicate `FT_Outline_Get_CBox'. (gray_compute_cbox): Remove this function. (gray_convert_glyph): Update to use `FT_Outline_Get_CBox'. 2016-06-20 Werner Lemberg <wl@gnu.org> [smooth] Remove compiler warnings. * src/smooth/ftgrays.c (gray_convert_glyph): Fix reports from clang. 2016-06-20 Alexei Podtelezhnikov <apodtele@gmail.com> [smooth] Sanitize memory management. * src/smooth/ftgrays.c (gray_convert_glyph): Cleaned up. 2016-06-18 Alexei Podtelezhnikov <apodtele@gmail.com> [smooth] Remove `band_shoot' that never worked. * src/smooth/ftgrays.c (gray_TWorker): Remove `band_shoot'. (gray_convert_glyph): Updated. 2016-06-17 Alexei Podtelezhnikov <apodtele@gmail.com> [raster, smooth] Handle FT_RENDER_POOL_SIZE better. * src/raster/ftraster.c (FT_MAX_BLACK_POOL): New macro. (ft_black_render): Updated. * src/smooth/ftgrays.c (FT_MAX_GRAY_POOL): New macro. (gray_raster_render): Updated. 2016-06-16 Werner Lemberg <wl@gnu.org> * src/base/md5.c: Updated to recent version. 2016-06-14 Alexei Podtelezhnikov <apodtele@gmail.com> * src/smooth/ftgrays.c (gray_hline): Optimize if-condition. 2016-06-13 Werner Lemberg <wl@gnu.org> [autofit] Add support for Cherokee script. * src/autofit/afblue.dat: Add blue zone data for Cherokee. * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated. * src/autofit/afscript.h: Add Cherokee standard characters. * src/autofit/afranges.c: Add Cherokee data. * src/autofit/afstyles.h: Add Cherokee data. 2016-06-09 David Capello <davidcapello@gmail.com> [cmake] Avoid modifying `ftconfig.h' and `ftoption.h' files. * CMakeLists.txt: Each time cmake is run those files are modified and the whole FreeType library is recompiled. With this change we change the files only if there are real modifications, so we can avoid recompilations. 2016-06-09 Werner Lemberg <wl@gnu.org> [bdf] Check number of properties (#48166). * src/bdf/bdflib.c (_bdf_parse_start): Implement. 2016-06-08 Alexei Podtelezhnikov <apodtele@gmail.com> [smooth] Re-enable new line renderer on 64-bit archs. * src/smooth/ftgrays.c (gray_render_line): Conditionally re-enable new implementation, where it is safe from overflows. 2016-06-08 Alexei Podtelezhnikov <apodtele@gmail.com> [smooth] Minor clean-ups. * src/smooth/ftgrays.c (gray_dump_cells): Move out of the way. (gray_render_span): Remove spurious casts and streamline. 2016-06-07 Werner Lemberg <wl@gnu.org> [autofit] Add support for Ethiopic script. * src/autofit/afblue.dat: Add blue zone data for Ethiopic. * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated. * src/autofit/afscript.h: Add Ethiopic standard characters. * src/autofit/afranges.c: Add Ethiopic data. * src/autofit/afstyles.h: Add Ethiopic data. 2016-06-07 Werner Lemberg <wl@gnu.org> [autofit] Fix compilation with VS2016 (#48126). This compiler doesn't recognize the end-of-comment sequence `*/' if it immediately follows non-ASCII characters. * src/autofit/afscript.h: Ensure whitespace before `*/'. 2016-06-04 Werner Lemberg <wl@gnu.org> Fix a test for named instances (#48122). This was missed while giving negative face indices an extended meaning. * src/base/ftobjs.c (Mac_Read_sfnt_Resource): Implement. 2016-05-31 Nikolaus Waxweiler <madigens@gmail.com> [truetype] Let SHPIX move points in the twilight zone in v40. * src/truetype/ttinterp.c (Ins_SHPIX): Allow SHPIX to move points in the twilight zone. Otherwise, treat SHPIX the same as DELTAP. Unbreaks various fonts such as older versions of Rokkitt and DTL Argo T Light that would glitch severely after calling ALIGNRP after a blocked SHPIX. 2016-05-30 Werner Lemberg <wl@gnu.org> [type42] Support `CharStrings' entry format as created by LilyPond. * src/type42/t42parse.c (t42_parse_charstrings): Handle entries having the format (foo) cvn 12345 def 2016-05-28 Werner Lemberg <wl@gnu.org> * src/autofit/afranges.c: Remove `UL' postfix from hex numbers. Suggested by Alexei. `UL' is only needed for 16bit compilers, but it seems noone is using this anymore (and we no longer test whether FreeType compiles in such an environment). Otherwise, it is easy to add the postfix to the `AF_UNICODE_RANGE' macro. 2016-05-26 Alexei Podtelezhnikov <apodtele@gmail.com> [smooth] Shrink bisection stack. The convergence of Bézier flatteners is fast with the deviation from straight line being asymptotically cut 4-fold on each bisection. This justifies smaller bisection stack size. * src/smooth/ftgrays.c (gray_TWorker): Remove common `bez_stack'. (gray_render_conic): Create and use conic `bez_stack'. Move back the band analysis from... (gray_conic_to): ... here. (gray_render_cubic): Create and use cubic `bez_stack'. Move back the band analysis from... (gray_cubic_to): ... here. (gray_move_to): Updated. 2016-05-25 Werner Lemberg <wl@gnu.org> [autofit] Fixes for Armenian and Gujarati ranges. * src/autofit/afranges.c (af_armn_uniranges): Corrected. (af_guru_nonbase_uniranges): Make U+0A3E a base character. 2016-05-24 Werner Lemberg <wl@gnu.org> [autofit] Add support for Armenian script. * src/autofit/afblue.dat: Add blue zone data for Armenian. * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated. * src/autofit/afscript.h: Add Armenian standard characters. * src/autofit/afranges.c: Add Armenian data. * src/autofit/afstyles.h: Add Armenian data. 2016-05-23 Werner Lemberg <wl@gnu.org> * builds/unix/unix-cc.in (LINK_LIBRARY): Use `-export-symbols'. This was commented about 10 years ago – I think the reason then to disable libtool's `-export-symbols' option was to give some badly programmed applications access to internal FreeType functions. I believe that we should no longer take care of such programs; the number of symbols exported should be rather restricted as much as possible. 2016-05-22 Werner Lemberg <wl@gnu.org> [autofit] Add blue-zone support for Gurmukhi script. This essentially moves the Gurmukhi script from the `Indic' hinter to the `Latin' hinter. * src/autofit/afblue.dat: Add blue zone data for Gurmukhi. * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated. * src/autofit/afscript.h: Add Gurmukhi standard characters and move data out of AF_CONFIG_OPTION_INDIC block. * src/autofit/afranges.c: Move Gurmukhi data out of AF_CONFIG_OPTION_INDIC block. * src/autofit/afstyles.h: Update Gurmukhi data; in particular, use AF_WRITING_SYSTEM_LATIN. 2016-05-21 Werner Lemberg <wl@gnu.org> Minor clang++ fixes. * src/base/ftobjs.c (FT_Add_Module), src/psaux/psobjs.c (ps_parser_load_field), src/type1/t1load.c (parse_subrs): Add initializer. * src/cache/ftccache.h (FTC_CACHE_TRYLOOP_END): Avoid implicit conversion from NULL to boolean. 2016-05-21 Werner Lemberg <wl@gnu.org> Work around a bug of the C 8.0.0.1 compiler on AIX 5.3 (#47955). * include/freetype/internal/ftmemory.h (cplusplus_typeof): Use braces for `extern "C++"'. 2016-05-17 Nikolaus Waxweiler <madigens@gmail.com> [truetype] Make TT_LOADER_SET_PP support subpixel hinting [3/3]. * src/truetype/ttgload.c (TT_LOADER_SET_PP): Replace macro with... (tt_loader_set_pp): ... this new function. Update all callers. 2016-05-17 Nikolaus Waxweiler <madigens@gmail.com> [truetype] New implementation of v38 bytecode interpreter [2/3]. This patch actually modifies the bytecode interpreter. See added comments in `ttinterp.h' for more information on this and the following commit in the series. * src/truetype/ttinterp.c (SUBPIXEL_HINTING): Replaced by... (NO_SUBPIXEL_HINTING, SUBPIXEL_HINTING_INFINALITY, SUBPIXEL_HINTING_MINIMAL): ...new macros. (Direct_Move, Direct_Move_X, Direct_Move_Y): Handle backward compatibility. Updated. (Ins_RS, Ins_FDEF, Ins_ENDF, Ins_CALL, Ins_LOOPCALL, Ins_MD): Updated. (Ins_INSTCTRL): Handle native ClearType mode flag. Updated. (Ins_FLIPPT, Ins_FLIPRGON, Ins_FLIPRGOFF): Handle backward compatibility. (Move_Zp2_Point): Ditto. (Ins_SHP): Updated. (Ins_SHPIX): Handle backward compatibility. Updated. (Ins_MSIRP, Ins_MDAP, Ins_MIAP, Ins_MDRP, Ins_MIRP): Updated. (Ins_ALIGNRP): Updated. (Ins_IUP, Ins_DELTAP): Handle backward compatibility. Updated. (Ins_GETINFO): Handle v38 flags. Updated. (TT_RunIns): Handle backward compatibility mode. Updated. 2016-05-17 Nikolaus Waxweiler <madigens@gmail.com> [truetype] New implementation of v38 bytecode interpreter [1/3]. This patch prepares data structures and the like. See added comments in `ttinterp.h' for more information on this and the following commits in the series. * devel/ftoption.h, include/freetype/config/ftoption.h (TT_CONFIG_OPTION_SUBPIXEL_HINTING): Assign values to differentiate between subpixel versions. (TT_SUPPORT_SUBPIXEL_HINTING_INFINALITY, TT_SUPPORT_SUBPIXEL_HINTING_MINIMAL): New macros. * include/freetype/ftttdrv.h (TT_INTERPRETER_VERSION_40): New macro. * include/freetype/internal/tttypes.h (TT_FaceRec): Updated. * src/truetype/ttinterp.h (TT_ExecContextRec): Define new fields `subpixel_hinting_lean', `vertical_lcd_lean', `backward_compatibility', `iupx_called', iupy_called', and `grayscale_cleartype' for new hinting mode. * src/truetype/ttdriver.c (tt_property_set): Handle v38 and v40 interpreters conditionally. * src/truetype/ttgload.c (TT_Hint_Glyph): Save phantom points unless in v38 backward compatibility mode. Updated. (compute_glyph_metrics): Add v38 backward compatibility mode constraint for adjusting advance widths. Updated. (tt_loader_init): Handle new flags `subpixel_hinting_lean', `grayscale_cleartype', and `vertical_lcd_lean'. Updated. (tt_get_metrics, TT_Process_Simple_Glyph, TT_LOADER_SET_PP): Updated. * src/truetype/ttobjs.c (tt_driver_init): Conditionally set default interpreter version number. * src/truetype/ttsubpix.c, src/truetype/ttsubpix.h: Updated. 2016-05-17 Werner Lemberg <wl@gnu.org> [cff] Fix matrix scaling (#47848). * include/freetype/config/ftstdlib.h (FT_LONG_MIN): New macro. * src/cff/cffparse.c (cff_parse_font_matrix): Use largest scaling value of all matrix coefficients to scale matrix. * src/cff/cffobjs.c (cff_face_init): Use `matrix->yx' member for matrix normalization if `matrix->yy' is zero. 2016-05-16 Werner Lemberg <wl@gnu.org> [base] Reject invalid sfnt Mac resource (#47891). * src/base/ftobjs.c (open_face_PS_from_sfnt_stream): Check validity of `CID ' and `TYPE1' table offset and length. 2016-05-16 Werner Lemberg <wl@gnu.org> [cid] Fix scanning for `StartData' and `/sfnts' (#47892). * src/cid/cidparse.c (STARTDATA, STARTDATA_LEN, SFNTS, SFNTS_LEN): New macros. (cid_parser_new): Fix and document algorithm. 2016-05-16 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> [truetype] Improve the recursive reference detector. The previous fix for #46372 misunderstood a composite glyph referring same component twice as a recursive reference. See the discussion https://lists.gnu.org/archive/html/freetype/2016-05/msg00000.html Thanks to Khaled Hosny for finding this issue. * src/truetype/ttgload.c (ft_list_get_node_at): A function to get the i-th node from FT_List. (load_truetype_glyph): In the traversal scan of the reference tree in the composite glyph, we clear the nodes filled by previous sibling chain. 2016-05-07 Werner Lemberg <wl@gnu.org> [cache] Allow value 0 for face ID. We never dereference `face_id', and some implementations might use a running number instead of a pointer. Additionally, disallowing value zero was undocumented. * src/cache/ftccmap.c (FTC_CMapCache_Lookup), src/cache/ftcmanag.c (FTC_Manager_LookupFace, FTC_Manager_RemoveFaceID): Remove test for `face_id'. 2016-05-05 Alexei Podtelezhnikov <apodtele@gmail.com> [smooth] More efficient accounting of conic splits and draws. A single decrement counter of segments to draw, instead of an array, contains all the information necessary to decide when to split and when to draw a conic segment. The number of splits before each draw is equal to the number of trailing zeros in the counter. * src/smooth/ftgrays.c (gray_TWorker): Remove `lev_stack'.

Suggested by Akaki Razmadze <razmadzekoko@gmail.com>. * src/autofit/afblue.dat (AF_BLUE_STRING_GEORGIAN_MKHEDRULI_BOTTOM): Updated. * src/autofit/afblue.c: Regenerated. 2016-04-16 David Capello <davidcapello@gmail.com> [cmake] Honor SKIP_INSTALL_* settings (as used in zlib). As FreeType depends on zlib, if we don't install zlib (e.g., because we defined SKIP_INSTALL_ALL), FreeType cannot be installed, too (cmake triggers an error saying that FreeType cannot be installed because zlib target isn't in the export set). * CMakeLists.txt: Honor `SKIP_INSTALL_HEADERS', `SKIP_INSTALL_LIBRARIES', and `SKIP_INSTALL_ALL' settings. 2016-04-16 Behdad Esfahbod <behdad@behdad.org> [truetype] Another fix for non-intermediate GX tuples. * src/truetype/ttgxvar.c (ft_var_apply_tuple): Add some missing cases. 2016-04-12 Alexei Podtelezhnikov <apodtele@gmail.com> Remove forgotten macro. * include/freetype/internal/internal.h [FT_INTERNAL_POSTSCRIPT_GLOBALS_H]: Remove. 2016-04-09 Werner Lemberg <wl@gnu.org> [autofit] Add support for Georgian scripts. Georgian is problematic, since `uppercase' forms of Mkhedruli (called Mtavruli) are not yet defined in Unicode, which means that proper blue zones can't be defined. However, there is already a proposal submitted to Unicode; see https://www.unicode.org/L2/L2016/16034-n4707-georgian.pdf Additionally, due to historical reasons, Unicode treats Khutsuri as the same script as Mkhedruli, and so does OpenType. However, since the two scripts have completely different shapes it can happen that blue zones differ considerably. The tag `geok' used here (derived from ISO 15924) to differentiate the two scripts is not an OpenType tag in use. If we now have a font that contains both glyphs for Mkhedruli and Khutsuri, and it uses OpenType features for both also, HarfBuzz unavoidably treats all glyphs as `geor'. As a consequence, blue zones for `geok' are not used for glyphs involved in the OpenType features. An issue not yet resolved is which OpenType feature should be used to access Mtavruli glyph shapes; right now, FreeType doesn't set up support for them, but it is easy to add them later on as soon as more information is available. * src/autofit/afblue.dat: Add blue zone data for Georgian. * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated. * src/autofit/afscript.h: Add Georgian standard characters. * src/autofit/afranges.c: Add Georgian data. * src/autofit/afstyles.h: Add Georgian data. 2016-04-05 Werner Lemberg <wl@gnu.org> [autofit] Provide dummy blue zone for pseudo script `none'.

However, HarfBuzz maps such tags to `DFLT', and without this commit the associated lookups were incorrectly assigned to the non-standard tags. - Let's assume we have a Bengali font, and the font's `DFLT' script tag handles the necessary lookups for Bengali, too. Without this commit, the `DFLT' lookups were assigned to ttfautohint's default script (usually `latn') before the standard lookups for Bengali were handled.

Scripts like Khmer have blue zones that can't be directly represented by Unicode characters. Instead, it is necessary to let HarfBuzz convert character clusters into proper glyph representation forms, then deriving the blue zone information from the resulting glyphs. * src/autofit/hbshim.c, src/autofit/hbshim.h: Replaced by... * src/autofit/afshaper.c, src/autofit/afshaper.h: ... these two new files, providing a new API to access HarfBuzz. The new API manages a HarfBuzz buffer with `af_shaper_buf_create' and `af_shaper_buf_destroy'. The buffer receives a UTF8 encoded string with function `af_shaper_get_cluster', and the resulting glyph data (indices, advance widths, vertical offsets) can be iteratively accessed with function `af_shaper_get_elem'. * src/autofit/afcjk.c (af_cjk_metrics_init_widths, af_cjk_metrics_init_blues, af_cjk_metrics_check_digits): Updated. * src/autofit/aflatin.c (af_latin_metrics_init_widths, af_latin_metrics_init_blues, af_latin_metrics_check_digits): Updated. * include/freetype/internal/fttrace.h: s/afharfbuzz/afshaper/. * src/autofit/afglobal.c: s/hbshim.h/afshaper.h/.

This patch fixes weaknesses in function `tt_face_load_font_dir'. - It incorrectly assumed that valid tables are always at the beginning. As a consequence, some valid tables after invalid entries (which are ignored) were never seen. - Duplicate table entries (this is, having the same tag) were not rejected. - The number of valid tables was sometimes too large, leading to access of invalid tables. * src/sfnt/ttload.c (check_table_dir): Add argument to return number of valid tables.

This patch introduces auxiliary code ranges that identify no-base characters; they refer to glyphs of a script that should be hinted without alignments to blue zones (mostly diacritics). It also splits off ranges for fallback scripts that handle subscript and superscript characters not covered by OpenType features. For example, this greatly helps improve the hinting of various phonetic alphabets, which contain a large amount characters that look like superscript glyphs. Finally, code ranges are updated to Unicode 8.0, and enclosed characters are removed in general since they normally look better if they stay unhinted. * src/autofit/afranges.c (af_latn_uniranges): Updated to Unicode 8.0. Split off superscript-like and subscript-like glyphs into... (af_latb_uniranges, af_latp_uniranges): ... these two new arrays.

(af_latin_hints_compute_segments): Collect information on maximum and minimum coordinates of `on' points; use this to add a constraint for the flat/round decision similar to `af_latin_metrics_init_blues'. 2015-08-04 Werner Lemberg <wl@gnu.org> Another left-shift bug (#45681). * src/base/ftobjs.c (IsMacBinary): Only accept positive values for `dlen'. 2015-08-03 Alexei Podtelezhnikov <apodtele@gmail.com> [base] Fix `ft_corner_orientation'. Remove casting from `FT_Long' to `FT_Int' that might change the sign of the return value and make it faster too. * src/base/ftcalc.c (ft_corner_orientation): On 32-bit systems, stay with 32-bit arithmetic when safe.

The function uses Newton's iterations instead of dividing vector components by its length, which needs a square root. This is, literally, a bit less accurate but a lot faster. * src/base/ftcalc.c (FT_Vector_NormLen): New function. 2015-06-28 Werner Lemberg <wl@gnu.org> * CMakeLists.txt: Always create `ftconfig.h'. For non-UNIX builds, the file stays unmodified. However, it's better to have the main configuration files at the same place regardless of the OS. 2015-06-28 Werner Lemberg <wl@gnu.org> * CMakeLists.txt: Improve MSVC support (#43737). 2015-06-28 Werner Lemberg <wl@gnu.org> [cmake] Check for libraries and create `ftoption.h'. * builds/FindHarfBuzz.cmake: New file, taken from https://trac.webkit.org/browser/trunk/Source/cmake/FindHarfBuzz.cmake * CMakeLists.Txt: Add path to local cmake modules. Find dependencies for zlib, bzip2, libpng, and harfbuzz. Create `ftoption.h' file. Set up include and linker stuff for libraries. 2015-06-28 Werner Lemberg <wl@gnu.org> * CMakeLists.txt: Fix creation of `ftconfig.h'. Check for UNIX header files using `check_include_file'. Set up correct header include directories. 2015-06-28 Werner Lemberg <wl@gnu.org> * CMakeLists.txt: Disallow in-source builds. 2015-06-27 Werner Lemberg <wl@gnu.org> * src/tools/docmaker/utils.py (check_output): Add missing `\n'. 2015-06-26 Werner Lemberg <wl@gnu.org> * CMakeLists.txt: Select platform-dependent `ftdebug.c'. 2015-06-25 Werner Lemberg <wl@gnu.org> * CMakeLists.txt: Use cmake functions for generating `ftconfig.h'. Additionally, do this for UNIX only. 2015-06-25 Werner Lemberg <wl@gnu.org> * CMakeLists.txt (BASE_SRCS): Use `ftbase.c' and `psnames.c'. 2015-06-25 Werner Lemberg <wl@gnu.org> Another adjustment to header locations. This change is a result of a discussion thread on freetype-devel https://lists.nongnu.org/archive/html/freetype-devel/2015-06/msg00041.html Re-introduce the `freetype2' subdirectory for all FreeType header files after installation, and rename the `freetype2' subdirectory in the git repository to `freetype'. * include/freetype2: Renamed to... * include/freetype: This. * CMakeLists.txt (PUBLIC_HEADERS, PUBLIC_CONFIG_HEADERS, PRIVATE_HEADERS): Updated.

We no longer `pollute' the namespace of possible header file names; instead we move `ft2build.h' up by one level so that it gets installed in the default include directory (e.g., /usr/local/include). After this commit, only `ft2build.h' stays in the compiler's include path. No visible changes for the user who follows the standard FreeType header inclusion rules. * include/*: Move to ... * include/freetype2/*: This directory, except `ft2build.h'. * CMakeLists.txt (PUBLIC_HEADERS, PUBLIC_CONFIG_HEADERS, PRIVATE_HEADERS), Jamfile (HDRMACRO, RefDoc), autogen.sh: Updated. * builds/amiga/include/config/ftconfig.h, builds/freetype.mk (PUBLIC_DIR), builds/symbian/bld.inf, builds/toplevel.mk (work), builds/unix/install.mk (install, uninstall), builds/unix/freetype2.in: Updated. * builds/unix/freetype-config.in: Updated.

This is just very basic stuff and just a little bit tested on GNU/Linux only. I won't delve into this since I'm not a Jam user. * Jamfile: Call `HDRMACRO' for `ftserv.h' also.

Problem reported by Grissiom <chaos.proton@gmail.com>; in https://lists.nongnu.org/archive/html/freetype/2015-05/msg00013.html there is an example code to trigger the bug. * src/truetype/ttobjs.c (tt_size_init_bytecode): Free old `size' data before allocating again. Bug most probably introduced four years ago in version 2.4.3. 2015-06-02 Werner Lemberg <wl@gnu.org> [raster] Add more tracing. * src/raster/ftraster.c (FT_TRACE7) [_STANDALONE_]: Define. (Vertical_Sweep_Span, Vertical_Sweep_Drop, Horizontal_Sweep_Span, Horizontal_Sweep_Drop, Render_Glyph): Add tracing calls. 2015-06-01 Werner Lemberg <wl@gnu.org> [truetype] While tracing opcodes, show code position and stack. * src/truetype/ttinterp.c: Change all existing TRACE7 calls to TRACE6. (opcode_name): Add string lengths. (TT_RunIns): Implement display of code position and stack. 2015-05-31 Werner Lemberg <wl@gnu.org> [truetype] In GX, make private point numbers work correctly. This is completely missing in Apple's documentation: If a `gvar' tuple uses private point numbers (this is, deltas are specified for some points only), the uncovered points must be interpolated for this tuple similar to the IUP bytecode instruction. Examples that need this functionality are glyphs `Oslash' and `Q' in Skia.ttf. * src/truetype/ttgxvar.c (tt_delta_shift, tt_delta_interpolate, tt_handle_deltas): New functions. (TT_Vary_Get_Glyph_Deltas): Renamed to... (TT_Vary_Apply_Glyph_Deltas): ... this; it directly processes the points and does no longer return an array of deltas. Add tracing information. Call `tt_handle_deltas' to interpolate missing deltas. Also fix a minor memory leak in case of error. * src/truetype/ttgxvar.h: Updated. * src/truetype/ttgload.c (TT_Process_Simple_Glyph, load_truetype_glyph): Updated. 2015-05-31 Werner Lemberg <wl@gnu.org> [truetype] In GX, make intermediate tuplets work at extrema. * src/truetype/ttgxvar.c (ft_var_apply_tuple): Fix range condition. 2015-05-31 Werner Lemberg <wl@gnu.org> [truetype] Add tracing information to GX code. * src/truetype/ttgxvar.c (ft_var_load_avar, ft_var_load_gvar, ft_var_apply_tuple, TT_Get_MM_Var, TT_Set_MM_Blend, TT_Set_Var_Design, tt_face_vary_cvt): Do it. 2015-05-28 Werner Lemberg <wl@gnu.org> * src/tools/apinames.c (names_dump): Fix invalid reference. Problem reported by Guzman Mosqueda, Jose R <jose.r.guzman.mosqueda@intel.com>. 2015-05-24 Werner Lemberg <wl@gnu.org> [truetype] Fix commit from 2015-05-22. * src/truetype/ttgload.c, src/truetype/ttinterp.c: Guard new code with `TT_CONFIG_OPTION_SUBPIXEL_HINTING'. Problem reported by Nikolaus Waxweiler <madigens@gmail.com>. 2015-05-23 Werner Lemberg <wl@gnu.org> [truetype] Fix return values of GETINFO bytecode instruction. * src/truetype/ttinterp.h (TT_ExecContextRec): New fields `vertical_lcd' and `gray_cleartype'. * src/truetype/ttgload.c (tt_loader_init): Initialize new fields. Change `symmetrical smoothing' to TRUE, since FreeType produces exactly this. * src/truetype/ttinterp.c (Ins_GETINFO): Fix selector/return bit values for symmetrical smoothing, namely 11/18. Handle bits for vertical LCD subpixels (8/15) and Gray ClearType (12/19). 2015-05-23 Werner Lemberg <wl@gnu.org> [truetype] Minor. * src/truetype/ttinterp.h (TT_ExecContext): s/subpixel/subpixel_hinting. * src/truetype/ttgload.c, src/truetype/ttgload.h: Updated. 2015-05-22 Werner Lemberg <wl@gnu.org> [truetype] Support selector index 3 of the INSTCTRL instruction. This flag activates `native ClearType hinting', disabling backward compatibility mode as described in Greg Hitchcocks whitepaper. In other words, it enables unrestricted functionality of all TrueType instructions in ClearType. * src/truetype/ttgload.c (tt_get_metrics): Call `sph_set_tweaks' unconditionally. (tt_loader_init): Unset `ignore_x_mode' flag if bit 2 of `GS.instruct_control' is active. * src/truetype/ttinterp.c (Ins_INSTCTRL): Handle selector index 3. (Ins_GETINFO): Updated. * docs/CHANGES: Document it. 2015-05-20 Werner Lemberg <wl@gnu.org> [truetype] Minor. * src/truetype/ttinterp.h (SetSuperRound): Fix type of `GridPeriod' argument. 2015-05-17 Werner Lemberg <wl@gnu.org> [truetype] Fix loading of composite glyphs. * src/truetype/ttgload.c (TT_Load_Composite_Glyph): If the ARGS_ARE_XY_VALUES flag is not set, handle argument values as unsigned. I trust `ttx' (which has exactly such code) that it does the right thing here... The reason that noone has ever noticed this bug is probably the fact that point-aligned subglyphs are rare, as are subglyphs with a number of points in the range [128;255], which is quite large (or even in the range [32768;65535], which is extremely unlikely). 2015-05-12 Chris Liddell <chris.liddell@artifex.com> [cff] Make the `*curveto' operators more tolerant. * src/cff/cf2intrp.c (cf2_interpT2CharString): The opcodes `vvcurveto', `hhcurveto', `vhcurveto', and `hvcurveto' all iterate, pulling values off the stack until the stack is exhausted. Implicitly the stack must be a multiple (or for subtly different behaviour) a multiple plus a specific number of extra values deep. If that's not the case, enforce it (as the old code did). 2015-05-12 Chris Liddell <chris.liddell@artifex.com> [cff] fix incremental interface with new cff code. * src/cff/cf2ft.c (cf2_getSeacComponent): When using the incremental interface to retrieve glyph data for a SEAC, it be left to the incremental interface callback to apply the encoding to raw character index (as it was in the previous code). 2015-04-29 Alexei Podtelezhnikov <apodtele@gmail.com> [autofit] Speed up IUP. * src/autofit/afhints.c (af_iup_interp): Separate trivial snapping to the same position from true interpolation, use `scale' to reduce divisions. 2015-04-28 Werner Lemberg <wl@gnu.org> [cff] Use `name' table for PS name if we have a SFNT-CFF. This follows the OpenType 1.7 specification. See https://tug.org/pipermail/tex-live/2015-April/036634.html for a discussion. * src/cff/cffdrivr.c (cff_get_ps_name): Use the `sfnt' service if we have an SFNT. 2015-04-27 Alexei Podtelezhnikov <apodtele@gmail.com> [truetype] Speed up IUP. * src/truetype/ttinterp.c (_iup_worker_interpolate): Separate trivial snapping to the same position from true interpolation. 2015-04-21 Werner Lemberg <wl@gnu.org> [autofit] By default, enable warping code but switch off warping. Suggested by Behdad. * include/config/ftoption.h: Define AF_CONFIG_OPTION_USE_WARPER. * src/autofit/afmodule.c (af_autofitter_init): Initialize `warping' with `false'. 2015-04-21 Werner Lemberg <wl@gnu.org> * docs/CHANGES: Updated. 2015-04-21 Werner Lemberg <wl@gnu.org> [autofit] Introduce `warping' property.

Problem reported by Behdad. * src/cff/cffdrivr.c (cff_get_advances): Handle SFNT case separately. * src/cff/cffgload.c (cff_slot_load): Use advance width and side bearing values from `hmtx' table if present. 2015-04-03 Alexei Podtelezhnikov <apodtele@gmail.com> * src/autofit/afhints.c (af_glyph_hints_reload): Use do-while loop. 2015-04-02 Alexei Podtelezhnikov <apodtele@gmail.com> * src/autofit/aflatin.c (af_latin_hint_edges): Reduce logic. 2015-04-01 Alexei Podtelezhnikov <apodtele@gmail.com> [autofit] Finish the thought. * src/autofit/afhints.c (af_direction_compute): make sure the long arm is never negative so that its `FT_ABS' is not necessary. 2015-04-01 Werner Lemberg <wl@gnu.org> [autofit] Call dumper functions for tracing. * src/autofit/afcjk.c (af_cjk_hints_apply): Remove dead code. * src/autofit/afhints.c (af_glyph_hints_dump_points): Minor improvement. * src/autofit/afmodule.c (af_autofitter_load_glyph): Implement it. 2015-04-01 Werner Lemberg <wl@gnu.org> [autofit] Make debugging stuff work again. The interface to ftgrid was broken in the series of commits starting with [autofit] Allocate AF_Loader on the stack instead of AF_Module. from 2015-01-14. * src/autofit/afmodule.c (_af_debug_hints_rec) [FT_DEBUG_AUTOFIT]: Use a global AF_GlyphHintsRec object for debugging.

This fixes a breakage caused by the commit `[raster] Remove 5-level gray AA mode from monochrome rasterizer.'. Problem reported by Markus Trippelsdorf <markus@trippelsdorf.de>. * src/raster/ftraster.c (ft_black_render): Handle `FT_RASTER_FLAG_AA'. * src/raster/ftrend1.c (ft_raster1_render): Remove gray AA mode remnants. 2015-01-18 Werner Lemberg <wl@gnu.org> * src/base/ftobjs.c (FT_New_Library): Fix compiler warning. 2015-01-18 Chris Liddell <chris.liddell@artifex.com> [raster] Fix Savannah bug #44022. Add fallback for glyphs with degenerate bounding boxes. If a glyph has only one very narrow feature, the bbox can end up with either the width or height of the bbox being 0, in which case no raster memory is allocated and no attempt is made to render the glyph. This is less than ideal when the drop-out compensation in the rendering code would actually result in the glyph being rendered. This problem can be observed with the `I' glyph (gid 47) in the Autodesk RomanS TrueType font. * src/raster/ftrend1.c (ft_raster1_render): Add a fallback if either dimension is zero to explicitly round up/down (instead of simply round). 2015-01-17 Werner Lemberg <wl@gnu.org> Add some tools to handle yearly copyright notice updates. We are now following the GNU guidelines: A new release automatically means that the copyright year of all affected files gets updated; it is no longer used to track years of modification changes. * src/tools/update-copyright-year: New Perl script. * src/tools/update-copyright: New shell script that calls `update-copyright-year' on all files. * src/tools/no-copyright: Exceptions that should not be handled by `update-copyright' 2015-01-14 Werner Lemberg <wl@gnu.org> * docs/CHANGES: Updated, using a description from Behdad. 2015-01-14 Behdad Esfahbod <behdad@behdad.org> * src/autofit/afmodule.c (af_autofitter_done): Fix compiler warning. 2015-01-14 Behdad Esfahbod <behdad@behdad.org> [autofit] Add embedded array of segments and edges. Avoids multiple mallocs per typical glyphs. With this and recent changes to avoid mallocs, the thread-safe stack-based loader is now as fast as the previous model that had one cached singleton. * src/autofit/afhints.h (AF_SEGMENTS_EMBEDDED, AF_EDGES_EMBEDDED): New macros. (AF_AxisHintsRec): Add two arrays for segments and edges. * src/autofit/afhints.c (af_axis_hints_new_segment): Only allocate data if number of segments exceeds given threshold value. (af_axis_hints_new_edge): Only allocate data if number of edges exceeds given threshold value. (af_glyph_hints_done): Updated. 2015-01-14 Behdad Esfahbod <behdad@behdad.org> [autofit] Add embedded arrays for points and contours. This avoids at least two malloc calls for typical glyphs. * src/autofit/afhints.h (AF_POINTS_EMBEDDED, AF_CONTOURS_EMBEDDED): New macros. (AF_GlyphHintsRec): Add two arrays for contours and points. * src/autofit/afhints.c (af_glyph_hints_init, af_glyph_hints_done): Updated. (af_glyph_hints_reload): Only allocate data if number of contours or points exceeds given threshold values. 2015-01-14 Behdad Esfahbod <behdad@behdad.org> [autofit] Allocate hints object on the stack. This avoids one malloc per load. * src/autofit/afloader.h (AF_LoaderRec): Change type of `hints' to `AF_GlyphHints'. Update prototype. * src/autofit/afloader.c (af_loader_init): Use `AF_GlyphHints' parameter instead of `FT_Memory'. (af_loader_done): Directly reset `load_hints'. (af_loader_load_g): Updated. * src/autofit/afmodule.c (af_autofitter_load_glyph): Use local `hints' object. 2015-01-14 Behdad Esfahbod <behdad@behdad.org> [autofit] Reuse slot glyph loader. No need to create a new glyph loader; we can reuse the one from `slot->internal->loader'. It's hard to tell why it was written that way originally, but new code looks sound and correct to me, and avoids lots of allocations. * src/autofit/afloader.c (af_loader_init): Change return type to `void'. Don't call `FT_GlyphLoader_New'. (af_loader_reset): Don't call `FT_GlyphLoader_Rewind'. (af_loader_load_g): Update code to use `internal->loader', which doesn't need copying of data. * src/autofit/afloader.h (AF_LoaderRec): Remove `gloader' member. Update prototype. * src/autofit/afmodule.c (af_autofitter_load_glyph): Updated. 2015-01-14 Behdad Esfahbod <behdad@behdad.org> [autofit] Remove (unused) support for composite glyphs. We never have to deal with composite glyphs in the autohinter, as those will be loaded into FORMAT_OUTLINE by the recursed `FT_Load_Glyph' function. In the rare cases that FT_LOAD_NO_RECURSE is set, it will imply FT_LOAD_NO_SCALE as per `FT_Load_Glyph', which then implies FT_LOAD_NO_HINTING: /* resolve load flags dependencies */ if ( load_flags & FT_LOAD_NO_RECURSE ) load_flags |= FT_LOAD_NO_SCALE | FT_LOAD_IGNORE_TRANSFORM; if ( load_flags & FT_LOAD_NO_SCALE ) { load_flags |= FT_LOAD_NO_HINTING | FT_LOAD_NO_BITMAP; load_flags &= ~FT_LOAD_RENDER; } and as such the auto-hinter is never called. Thus, the recursion in `af_loader_load_g' never actually happens. So remove the depth counter as well. * src/autofit/afloader.c (af_loader_load_g): Remove `depth' parameter. <FT_GLYPH_FORMAT_COMPOSITE>: Remove associated code. (af_loader_load_glyph): Updated. 2015-01-14 Behdad Esfahbod <behdad@behdad.org> [raster] Fix uninitialized memory access. Apparently `ras.cProfile' might be uninitialized. This will be the case if `ras.top == ras.cProfile->offset', as can be seen in `End_Profile'. The overshoot code introduced in a change `Fix B/W rasterization of subglyphs with different drop-out modes.' (from 2009-06-18) violated this, accessing `ras.cProfile->flags' unconditionally just before calling `End_Profile' (which then detected that `cProfile' is uninitialized and didn't touch it). This was harmless, and was not detected by valgrind before because the objects were allocated on the `raster_pool', which was always initialized. With recent change to allocate raster buffers on the stack, valgrind now reported this invalid access. * src/raster/ftraster.c (Convert_Glyph): Don't access an uninitialized `cProfile'. 2015-01-14 Behdad Esfahbod <behdad@behdad.org> [smooth] Fix uninitialized memory access. Looks like `ras.span_y' could always be used without initialization. This was never detected by valgrind before because the library-wide `raster_pool' was used for the worker object and `raster_pool' was originally zero'ed. But subsequent reuses of it were using `span_y' uninitialized. With the recent change to not use `render_pool' and allocate worker and buffer on the stack, valgrind now detects this uninitialized access. * src/smooth/ftgrays.c (gray_raster_render): Initialize `ras.span_y'. 2015-01-14 Behdad Esfahbod <behdad@behdad.org> [base] Don't initialize unused `driver->glyph_loader'. * src/base/ftobjs.c (Destroy_Driver): Don't call `FT_GlyphLoader_Done'. (FT_Add_Module): Don't call `FT_GlyphLoader_New'. 2015-01-14 Behdad Esfahbod <behdad@behdad.org> [base] Don't allocate `library->raster_pool' anymore. It's unused after the following commits: [raster] Allocate render pool for mono rasterizer on the stack. [raster] Remove 5-level gray AA mode from monochrome rasterizer. The value of FT_RENDER_POOL_SIZE still serves the purpose it used to serve, which is, to adjust the pool size. But the pool is now allocated on the stack on demand. * src/base/ftobjs.c (FT_New_Library, FT_Done_Library): Implement. 2015-01-14 Behdad Esfahbod <behdad@behdad.org> [base] Do not reorder library->renderers upon use. Instead of keeping `library->renderers' in a MRU order, just leave it as-is. The MRU machinery wasn't thread-safe. With this patch, rasterizing glyphs from different faces from different threads doesn't fail choosing rasterizer (FT_Err_Cannot_Render_Glyph). Easiest to see that crash was to add a `printf' (or otherwise let thread yield in FT_Throw with debugging enabled). * src/base/ftobjs.c (FT_Render_Glyph_Internal), src/base/ftoutln.c (FT_Outline_Render): Don't call `FT_Set_Renderer'. 2015-01-14 Behdad Esfahbod <behdad@behdad.org> [raster] Allocate render pool for mono rasterizer on the stack. Instead of using the `render_pool' member of `FT_Library' that is provided down to the rasterizer, completely ignore that and allocate needed objects on the stack instead. With this patch, rasterizing glyphs from different faces from different threads doesn't crash in the monochrome rasterizer. * src/raster/ftraster.c (black_TRaster): Remove `buffer', `buffer_size', and `worker' members. (ft_black_render): Create `buffer' locally. (ft_black_reset): Updated. 2015-01-14 Behdad Esfahbod <behdad@behdad.org> [raster] Remove 5-level gray AA mode from monochrome rasterizer. It was off by default and couldn't be turned on at runtime. And the smooth rasterizer superseded it over ten years ago. No point in keeping. Comments suggested that it was there for compatibility with FreeType 1. 550 lines down. * src/raster/ftraster.c (FT_RASTER_OPTION_ANTI_ALIASING, RASTER_GRAY_LINES): Remove macros and all associated code. (black_TWorker): Remove `gray_min_x' and `gray_max_x'. (black_TRaster): Remove `grays' and `gray_width'. (Vertical_Sweep_Init, Vertical_Sweep_Span, Vertical_Sweep_Drop, ft_black_render): Updated. * src/raster/ftrend1.c (ft_raster1_render): Simplify code. (ft_raster5_renderer_class): Removed. 2015-01-14 Behdad Esfahbod <behdad@behdad.org> [smooth] Allocate render pool for smooth rasterizer on the stack. Instead of using the `render_pool' member of `FT_Library' that is provided down to the rasterizer, completely ignore that and allocate needed objects on the stack instead. With this patch, rasterizing glyphs from different faces from different threads doesn't crash in the smooth rasterizer. Bugs: https://bugzilla.redhat.com/show_bug.cgi?id=678397 https://bugzilla.redhat.com/show_bug.cgi?id=1004315 https://bugzilla.redhat.com/show_bug.cgi?id=1165471 https://bugs.freedesktop.org/show_bug.cgi?id=69034 * src/smooth/ftgrays.c (gray_TRaster): Remove `buffer', `buffer_size', `band_size', and `worker' members. (gray_raster_render): Create `buffer', `buffer_size', and `band_size' locally. (gray_raster_reset): Updated. 2015-01-14 Behdad Esfahbod <behdad@behdad.org> [truetype] Allocate TT_ExecContext in TT_Size instead of TT_Driver. Previously the code had stipulation for using a per-TT_Size exec context if `size->debug' was true. But there was no way that `size->debug' could *ever* be true. As such, the code was always using the singleton `TT_ExecContext' that was stored in `TT_Driver'. This was, clearly, not threadsafe. With this patch, loading glyphs from different faces from different threads doesn't crash in the bytecode loader code. * src/truetype/ttobjs.h (TT_SizeRec): Remove `debug' member. (TT_DriverRec): Remove `context' member. * src/truetype/ttobjs.c (tt_size_run_fpgm, tt_size_run_prep): Remove `TT_ExecContext' code related to a global `TT_Driver' object. (tt_driver_done): Don't remove `TT_ExecContext' object here but ... (tt_size_done_bytecode): ... here. (tt_driver_init): Don't create `TT_ExecContext' object here but ... (tt_size_init_bytecode): ... here, only on demand. * src/truetype/ttinterp.c (TT_Run_Context): Remove defunct debug code. (TT_New_Context): Remove `TT_ExecContext' code related to a global `TT_Driver' object. * src/truetype/ttinterp.h: Updated. * src/truetype/ttgload.c (TT_Hint_Glyph, tt_loader_init): Updated. 2015-01-14 Behdad Esfahbod <behdad@behdad.org> [autofit] Allocate AF_Loader on the stack instead of AF_Module. Stop sharing a global `AF_Loader'. Allocate one on the stack during glyph load. Right now this results in about 25% slowdown, to be fixed in a following commit. With this patch loading glyphs from different faces from different threads doesn't immediately crash in the autohinting loader code. Bugs: https://bugzilla.redhat.com/show_bug.cgi?id=1164941 * src/autofit/afloader.c (af_loader_init): Pass `AF_Loader' and `FT_Memory' instead of `AF_Module' as arguments. (af_loader_reset, af_loader_load_glyph): Also pass `loader' as argument. (af_loader_done): Use `AF_Loader' instead of `AF_Module' as argument. * src/autofit/afmodule.c (af_autofitter_init): Don't call `af_loader_init'. (af_autofitter_done): Don't call `af_loader_done'. (af_autofitter_load_glyph): Use a local `AF_Loader' object. * src/autofit/afloader.h: Include `afmodule.h'. Update prototypes. Move typedef for `AF_Module' to... * src/autofit/afmodule.h: ... this place. No longer include `afloader.h'. 2015-01-14 Behdad Esfahbod <behdad@behdad.org> * src/type42/t42objs.h (T42_DriverRec): Remove unused member. 2015-01-12 Werner Lemberg <wl@gnu.org> Fix Savannah bug #43976. Assure that FreeType's internal include directories are found before `CPPFLAGS' (which might be set by the user in the environment), and `CPPFLAGS' before `CFLAGS'. * builds/freetype.mk (FT_CFLAGS): Don't add `INCLUDE_FLAGS'. (FT_COMPILE): Make this a special variable for compiling only the files handled in `freetype.mk'. (.c.$O): Removed, unused. * src/*/rules.mk (*_COMPILE): Fix order of include directories. 2015-01-11 Werner Lemberg <wl@gnu.org> [truetype] Prettifying. * src/truetype/ttinterp.c (project, dualproj, fast_project, fast_dualproj): Rename to... (PROJECT, DUALPROJ, FAST_PROJECT, FAST_DUALPROJ): ... this. 2015-01-11 Werner Lemberg <wl@gnu.org> * src/truetype/ttinterp.c (Ins_JROT, Ins_JROF): Simplify. Based on a patch from Behdad. 2015-01-11 Werner Lemberg <wl@gnu.org> * src/truetype/ttinterp.c (Ins_SxVTL): Simplify function call. 2015-01-11 Werner Lemberg <wl@gnu.org> * src/truetype/ttinterp.c (Normalize): Remove unused argument. 2015-01-11 Werner Lemberg <wl@gnu.org> [truetype] More macro expansions. * src/truetype/ttinterp.c (FT_UNUSED_EXEC): Remove macro by expansion. 2015-01-11 Werner Lemberg <wl@gnu.org> [truetype] More macro expansions. * src/truetype/ttinterp.c (INS_ARG): Remove macro by expansion, adjusting function calls where necessary. (FT_UNUSED_ARG): Removed, no longer needed. 2015-01-10 Werner Lemberg <wl@gnu.org> [truetype] More macro expansions. Based on a patch from Behdad. * src/truetype/ttinterp.c (DO_*): Expand macros into corresponding `Ins_*' functions. (TT_RunIns): Replace `DO_*' macros with `Ins_*' function calls. (ARRAY_BOUND_ERROR): Remove second definition, which is no longer needed. (Ins_SVTCA, Ins_SPVTCA, Ins_SFVTCA): Replaced with... (Ins_SxyTCA): New function. 2015-01-10 Werner Lemberg <wl@gnu.org> [truetype] Remove TT_CONFIG_OPTION_INTERPRETER_SWITCH. Behdad suggested this code simplification, and nobody objected... * include/config/ftoption.h, devel/ftoption.h (TT_CONFIG_OPTION_INTERPRETER_SWITCH): Remove. * src/truetype/ttinterp.c [TT_CONFIG_OPTION_INTERPRETER_SWITCH]: Remove related code. (ARRAY_BOUND_ERROR): Use do-while loop. 2015-01-10 Werner Lemberg <wl@gnu.org> [truetype] More macro expansions. * src/truetype/ttinterp.c, src/truetype/ttinterp.h (EXEC_ARG_, EXEC_ARG): Remove by replacing with expansion. 2015-01-10 Werner Lemberg <wl@gnu.org> [truetype] More macro expansions. Based on a patch from Behdad. * src/truetype/ttinterp.c (SKIP_Code, GET_ShortIns, NORMalize, SET_SuperRound, ROUND_None, INS_Goto_CodeRange, CUR_Func_move, CUR_Func_move_orig, CUR_Func_round, CUR_Func_cur_ppem, CUR_Func_read_cvt, CUR_Func_write_cvt, CUR_Func_move_cvt, CURRENT_Ratio, INS_SxVTL, COMPUTE_Funcs, COMPUTE_Round, COMPUTE_Point_Displacement, MOVE_Zp2_Point): Remove by replacing with expansion. (Cur_Func_project, CUR_Func_dualproj, CUR_fast_project, CUR_fast_dualproj): Replace with macros `project', `dualproj', `fast_project', `fast_dualproj'. 2015-01-10 Werner Lemberg <wl@gnu.org> [truetype] More macro expansions. * src/truetype/ttinterp.c (EXEC_OP_, EXEC_OP): Remove by replacing with expansion. 2015-01-10 Werner Lemberg <wl@gnu.org> [truetype] Remove code for static TrueType interpreter. This is a follow-up patch. * src/truetype/ttinterp.c, src/truetype/ttinterp.h [TT_CONFIG_OPTION_STATIC_INTERPRETER, TT_CONFIG_OPTION_STATIC_RASTER]: Remove macros and related code. 2015-01-10 Werner Lemberg <wl@gnu.org> * src/truetype/ttinterp.c (CUR): Remove by replacing with expansion.

(Random): Implement and use a 32bit `xorshift' algorithm. 2016-12-30 Werner Lemberg <wl@gnu.org> [ftfuzzer] Restrict number of tested bitmap strikes. Malformed fonts often have large values for the number of bitmap strikes, and FreeType doesn't check the validity of all bitmap strikes in advance. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=353 * src/tools/ftfuzzer/ftfuzzer.cc: Include `stdlib.h' for `rand'. (Random): Small class to provide n randomly selected numbers (without repetition) out of the value set [1,N]. (LLVMFuzzerTestOneInput): Use it to test only up to 10 bitmap strikes. 2016-12-29 Werner Lemberg <wl@gnu.org> [truetype] Variation font API stability issues. Make some functions work before a call to `TT_Set_MM_Blend'. * src/truetype/ttgxvar.c (tt_hadvance_adjust): Exit immediately if we don't blend. (TT_Get_MM_Blend, TT_Get_Var_Design): Return default values if we don't blend. 2016-12-29 Werner Lemberg <wl@gnu.org> * src/truetype/ttgxvar.c (TT_Get_MM_Var): Check axis data. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=348 2016-12-29 Werner Lemberg <wl@gnu.org> [truetype] Tracing fixes. * src/truetype/ttgxvar.c (tt_hadvance_adjust): Emit correct information. (TT_Set_Var_Design): Fix typo. (TT_Get_Var_Design): Fix typos. 2016-12-29 Werner Lemberg <wl@gnu.org> */*: Use `0.5f' for tracing 16.16 numbers. 2016-12-29 Werner Lemberg <wl@gnu.org> [pcf] Protect against gzip bombs. Fix suggested by Kostya; reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=345 * src/pcf/pcfread.c (pcf_read_TOC): Limit number of TOC entries to 1024. 2016-12-28 Werner Lemberg <wl@gnu.org> [psnames] Only declare, not define, data in `pstables.h' (#49949). Pdfium includes `pstables.h' a second time; moving the definition from `pstables.h' to `psmodule.c' saves more than 60kByte data segment space for this case. * src/tools/glnames.py (StringTable::dump, StringTable::dump_sublist, dump_encoding, dump_array): Emit additional code to only define tables if `DEFINE_PS_TABLES' is set. * src/psnames/pstables.h: Regenerated. * src/psnames/psmodule.c (DEFINE_PS_TABLES): Define. 2016-12-28 Werner Lemberg <wl@gnu.org> [cff] Catch `blend' op in non-variant fonts. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=334 * src/cff/cf2intrp.c (cf2_interpT2CharString) <cf2_cmdBLEND>: Don't allow `blend' op for non-variant fonts. 2016-12-28 Werner Lemberg <wl@gnu.org> [cff] Better check of number of blends. * src/cff/cf2intrp.c (cf2_interpT2CharString) <cf2_cmdBLEND>, src/cff/cffparse.c (cff_parse_blend): Compare number of blends with stack size. 2016-12-27 Werner Lemberg <wl@gnu.org> Documentation updates. * docs/CHANGES: Add missing information. * docs/formats.txt: Rewritten and updated. 2016-12-27 Werner Lemberg <wl@gnu.org> [truetype, type1] Implement `FT_Get_Var_Design_Coordinates'. * src/truetype/ttgxvar.c (TT_Get_Var_Design): Implement. (TT_Set_Var_Design): Fix tracing. * src/type1/t1load.c (T1_Get_Var_Design): Implement. 2016-12-24 Werner Lemberg <wl@gnu.org> * src/truetype/ttpload.c (tt_face_load_hdmx): Ignore `version'. Problem reported by 張俊芝 <418092625@qq.com>. 2016-12-24 Werner Lemberg <wl@gnu.org> * src/sfnt/ttsbit.c (tt_face_load_sbit): Allow more version values. Some fonts seem to have the `version' field in the wrong byte order. Problem reported by 張俊芝 <418092625@qq.com>. 2016-12-24 Werner Lemberg <wl@gnu.org> * src/truetype/ttpload.c (tt_face_load_loca): Sanitize table length. This trivial fix allows us to accept more fonts. Problem reported by 張俊芝 <418092625@qq.com>. 2016-12-24 Werner Lemberg <wl@gnu.org> * src/sfnt/sfobjs.c (sfnt_init_face): Fix tracing. 2016-12-22 Werner Lemberg <wl@gnu.org> * CMakeLists.txt: Make it work with cmake 2.8.11.2 (#49909). 2016-12-22 Werner Lemberg <wl@gnu.org> Ensure used preprocessor symbols are defined (#49790). * builds/unix/ftconfig.in, builds/vms/ftconfig.h, include/freetype/config/ftconfig.h: Check `__GNUC__', `__IBMC__', and `__SUNPRO_C' correctly. 2016-12-22 Werner Lemberg <wl@gnu.org> * src/base/ftrfork.c (FT_Raccess_Get_DataOffsets): Check `count'. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=308 2016-12-22 Werner Lemberg <wl@gnu.org> [cff] Protect against invalid `vsindex' and `blend' values. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=305 * src/cff/cf2intrp.c (cf2_interpT2CharString) <cf2_cmdVSINDEX, cf2_cmdBLEND>: Implement it. 2016-12-22 Werner Lemberg <wl@gnu.org> [ftfuzzer] Always use Adobe CFF engine. * src/tools/ftfuzzer/ftfuzzer.cc (FT_Global::FT_Global): Implement it. 2016-12-21 Werner Lemberg <wl@gnu.org> * src/truetype/ttgxvar.c (TT_Vary_Apply_Glyph_Deltas): Thinko. I should really stop coding late in the evening... Thanks again to Ben for checking. 2016-12-21 Werner Lemberg <wl@gnu.org> [autofit] Support variation fonts. (This ChangeLog entry was added later on.) * src/autofit/afglobal.c (af_face_globals_free): Remove useless code. * src/base/ftmm.c (FT_Set_MM_Design_Coordinates, * FT_Set_Var_Design_Coordinates, FT_Set_MM_Blend_Coordinates, FT_Set_Var_Blend_Coordinates): Finalize auto-hinter data to enforce recomputation. Note that this is a brute-force method which should be improved. 2016-12-21 Werner Lemberg <wl@gnu.org> * src/truetype/ttgxvar.c (TT_Vary_Apply_Glyph_Deltas): Thinko.

This also fixes a bug introduced in 2016-10-01 which prevents display of embedded bitmap fonts that use the `sbix' format. * src/sfnt/ttsbit.c (tt_face_load_sbit): Store `sbix' size and offset also in `ebdt_size' and `ebdt_start', respectively. This makes the test for an embedded bitmap data table succeed for this format. (tt_face_load_strike_metrics) <TT_SBIT_TABLE_TYPE_SBIX>: Use `ebdt_size' and `ebdt_start' (tt_face_load_sbix_image): Ditto. 2016-11-06 Seigo Nonaka <nona@google.com> Werner Lemberg <wl@gnu.org> Introduce a way of quickly retrieving (embedded) bitmap metrics. `FT_Load_Glyph' doesn't generate a bitmap for a non-bitmap glyph until the user calls `FT_Render_Glyph'. However, it always allocates memory for bitmaps and copies or decodes the contents of a bitmap glyph, which can be quite slow for PNG data. * include/freetype/freetype.h (FT_LOAD_BITMAP_METRICS_ONLY): New macro. * src/base/ftobjs.c (FT_Load_Glyph): Unset FT_LOAD_RENDER if FT_LOAD_BITMAP_METRICS_ONLY is used. * src/sfnt/ttsbit.c (tt_sbit_decoder_alloc_bitmap, tt_sbit_decoder_load_bitmap): Add argument to control allocation of the glyph slot. (tt_sbit_decoder_load_image, tt_sbit_decoder_load_compound, tt_face_load_sbit_image): Updated. * src/pcf/pcfdrivr.c (PCF_Glyph_Load): Quickly exit if `FT_LOAD_BITMAP_METRICS_ONLY' is set. * src/pfr/pfrsbit.c, src/pfr/pfrsbit.h (pfr_slot_load_bitmap): Add argument to control allocation of the glyph slot. * src/pfr/pfrobjs (pfr_slot_load): Updated. * src/winfonts/winfnt.c (FNT_Load_Glyph): Ditto. * docs/CHANGES: Updated. 2016-11-06 Werner Lemberg <wl@gnu.org> Synchronize with gnulib (#49448). * include/freetype/config/ftconfig.h, builds/unix/ftconfig.in, builds/vms/ftconfig.h (FT_TYPEOF): Update code to use definition in current version of `intprops.h'. Other minor synchronization to reduce code differences between the three files. 2016-11-03 Behdad Esfahbod <behdad@behdad.org> [truetype] Clamp variation requests to valid range. This is required by OpenType 1.8; it also avoids rounding surprises. * src/truetype/ttgxvar.c (TT_Set_Var_Design): Clamp design coordinates outside of the allowed range to always stay within the range instead of producing an error. 2016-10-29 Werner Lemberg <wl@gnu.org> [truetype] Remove clang warnings. * src/truetype/ttinterp.h (TT_ExecContextRec): Using `FT_ULong' for loop counter handling. * src/truetype/ttinterp.c: Updated. (Ins_SCANTYPE): Use signed constant. (TT_RunIns): Ensure `num_twilight_points' is 16bit. 2016-10-27 Werner Lemberg <wl@gnu.org> [truetype] Fix commit from 2014-11-24. Problem reported by Hin-Tak Leung <htl10@users.sourceforge.net>. * src/truetype/ttpload.c (tt_face_load_hdmx): Fix file checking logic. 2016-10-26 Werner Lemberg <wl@gnu.org> Add `FT_Get_{MM,Var}_Blend_Coordinates' functions. * include/freetype/ftmm.h: Declare. * include/freetype/internal/services/svmm.h (FT_Get_MM_Blend_Func): New typedef.

Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=81 2016-10-25 Alexei Podtelezhnikov <apodtele@gmail.com> [cff] Correct cmap format reporting (#24819). * src/cff/cffdrivr.c (cff_get_cmap_info): Throw an error on synthetic charmap instead of guessing its format and language. 2016-10-22 Werner Lemberg <wl@gnu.org> [truetype] Fix SCANTYPE instruction (#49394). * src/truetype/ttinterp.c (Ins_SCANTYPE): Only use lower 16bits. 2016-10-22 Werner Lemberg <wl@gnu.org> [sfnt] Improve handling of invalid post 2.5 tables [#49393]. * src/sfnt/ttpost.c (load_format_25): We need at least a single table entry. 2016-10-14 Werner Lemberg <wl@gnu.org> [truetype] Fix handling of `cvar' table data. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=53 * src/truetype/ttgxvar.c (tt_face_vary_cvt): Ignore invalid CVT indices. 2016-10-11 Werner Lemberg <wl@gnu.org> [psaux] Fix handling of invalid flex subrs. Problem reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=52 * src/psaux/t1decode.c (t1_decoder_parse_charstrings) <op_callothersubr>: Set `flex_state' after error checking. 2016-10-11 Werner Lemberg <wl@gnu.org> * src/truetype/ttgxvar.c (tt_done_blend): Fix deallocation. 2016-10-08 Werner Lemberg <wl@gnu.org> * src/cid/cidload.c (cid_face_open): Properly propagate `error'. 2016-10-08 Werner Lemberg <wl@gnu.org> [cid] Fix parsing of subr offsets. Bug introduced 2016-05-16. * src/cid/cidparse.c (cid_parser_new): Fix off-by-one error. 2016-10-01 Werner Lemberg <wl@gnu.org> [sfnt] Disable bitmap strikes if we don't have a bitmap data table. * src/sfnt/ttsbit.c (tt_face_load_sbit): Check whether we have a bitmap data table. 2016-10-01 Alexei Podtelezhnikov <apodtele@gmail.com> [smooth] Remove impossibility. * src/smooth/ftgrays.c (TWorker): Rearrange fields. (gray_convert_glyph): Remove impossible condition and clean up. 2016-09-29 Werner Lemberg <wl@gnu.org> [pcf] Enrich family name with foundry name and glyph width info. This is a very old patch from openSuSE (from 2006, submitted to FreeType in 2011) that I forgot to apply. https://build.opensuse.org/package/view_file/openSUSE:Factory/freetype2/freetype2-bitmap-foundry.patch Prepend the foundry name plus a space to the family name. There are many fonts just called `Fixed' which look completely different, and which have nothing to do with each other. When selecting `Fixed' in KDE or Gnome one gets results that appear rather random, the style changes often if one changes the size and one cannot select some fonts at all. We also check whether we have `wide' characters; all put together, we get family names like `Sony Fixed' or `Misc Fixed Wide'. * src/pcf/pcfread.c (pcf_load_font): Implement it. * docs/CHANGES: Document it. 2016-09-29 Werner Lemberg <wl@gnu.org> [ftfuzzer] Speed up. * src/tools/ftfuzzer/ftfuzzer.cc (LLVMFuzzerTestOneInput): Don't check for embedded bitmaps if we have a non-default instance. 2016-09-29 Werner Lemberg <wl@gnu.org> [truetype] Disallow bitmap strikes for non-default instances. Also speed up access of default instances if GX variations are active. * include/freetype/internal/tttypes.h (TT_FaceRec): Add `is_default_instance' member. * src/sfnt/sfobjs.c (sfnt_init_face): Initialize `is_default_instance'. * src/truetype/ttgload.c (TT_Process_Simple_Glyph, load_truetype_glyph): Add test for default instance.

This avoids additional calls to `tt_face_lookup_table' for the `glyf' table, which can be expensive. * include/freetype/internal/tttypes.h (TT_LoaderRec): Move `glyf_offset' field to ... (TT_FaceRec): ... this structure. * src/truetype/ttgload.c (load_truetype_glyph): Updated. (tt_loader_init): Move initialization of `glyf_offset' to ... * src/truetype/ttpload.c (tt_face_load_loca): ... this function. 2016-09-27 Werner Lemberg <wl@gnu.org> [truetype] Introduce dynamic limits for some bytecode opcodes. This speeds up FreeType's handling of malformed fonts. * src/truetype/ttinterp.c (TT_RunIns): Set up limits for the number of twilight points, the total number of negative jumps, and the total number of loops in LOOPCALL opcodes. The values are based on the number of points and entries in the CVT table. (Ins_JMPR): Test negative jump counter. (Ins_LOOPCALL): Test loopcall counter. * src/truetype/ttinterp.h (TT_ExecContext): Updated. * docs/CHANGES: Updated. 2016-09-25 Werner Lemberg <wl@gnu.org> [truetype] Sanitize only last entry of `loca' table. Without this patch, a loca sequence like `0 100000 0 100000 ...', where value 100000 is larger than the `glyf' table size, makes FreeType handle the whole `glyf' table as a single glyph again and again, which is certainly invalid (and can be very slow, too). * src/truetype/ttpload.c (tt_face_get_location): Implement. Improve tracing messages. 2016-09-25 Werner Lemberg <wl@gnu.org> * src/tools/ftfuzzer/ftfuzzer.cc (LLVMFuzzerTestOneInput): Fix typo. 2016-09-24 Werner Lemberg <wl@gnu.org> [autofit] Tracing fixes. * src/autofit/afmodule.c (af_autofitter_load_glyph): Call dumping functions only if we actually do tracing. 2016-09-22 Alexei Podtelezhnikov <apodtele@gmail.com> [smooth] Reduce divisions in the line renderer.

The algorithm calls `gray_set_cell' at the start of each new contour or when the contours cross the cell boundaries. Double-checking for that is wasteful. * src/smooth/ftgrays.c (gray_set_cell): Remove check for a new cell. (gray_convert_glyph): Remove initialization introduced by 44b172e88. 2016-09-10 Werner Lemberg <wl@gnu.org> [sfnt] Fix previous commit. Problems reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=40 We now map the strike index right before accessing the physical data, not earlier. * src/sfnt/sfobjs.c (sfnt_load_face): Set `face->sbit_strike_map' after creating the map so that... * src/sfnt/ttsbit.c (tt_face_load_strike_metrics): ... this function can be used before and after setting up `sbit_strike_map'.

Use better values for call to `FT_Set_Char_Size'. 2016-09-09 Werner Lemberg <wl@gnu.org> [sfnt] Don't provide (completely) broken strike data. FreeType tries to sanitize strike header data; we now reject completely broken ones. * include/freetype/internal/tttypes.h (TT_FaceRec): New `sbit_strike_map' array pointer. * src/base/ftobjs.c (FT_Match_Size): Reject matches where either width or height would be zero. Add tracing message in case of error. * src/sfnt/sfobjs.c (sfnt_load_face): Populate `sbit_strike_map', only using (more or less) valid strike header data for FT_Face's `available_sizes' array.

It turns out that there is significant cost associated with `FT_Span' creation and calls to `gray_render_span' because it happens so frequently. This removes these steps from our internal use but leaves it alone for `FT_RASTER_FLAG_DIRECT" to preserve API. The speed gain is about 5%. * src/smooth/ftgrays.c (gray_render_span): Removed. The code is migrated to... (gray_hline): ... here. 2016-08-30 Alexei Podtelezhnikov <apodtele@gmail.com> [smooth] Streamline pixmap drawing a bit more.

This removes unnecessary complexity of span merging and buffering. Instead, the spans are rendered as they come, speeding up the rendering by about 5% as a result. * src/smooth/ftgrays.c [FT_MAX_GRAY_SPANS]: Macro removed. (gray_TWorker): Remove span buffer and related fields. (gray_sweep, gray_hline): Updated. * include/freetype/ftimage.h: Remove documentation note about `FT_MAX_GRAY_SPANS', which was never in `ftoption.h' and is now gone. 2016-08-16 Werner Lemberg <wl@gnu.org> [truetype] Fix `MPS' instruction. According to Greg Hitchcock, MPS in DWrite really returns the point size. * src/truetype/ttobjs.h (TT_SizeRec): Add `point_size' member. * src/truetype/ttdriver.c (tt_size_request): Set `point_size'. * src/truetype/ttinterp.h (TT_ExecContextRec): Add `pointSize' member. * src/truetype/ttinterp.c (TT_Load_Context): Updated. (Ins_MPS): Fix instruction. 2016-08-16 Werner Lemberg <wl@gnu.org> [lzw] Optimize last commit. * src/lzw/ftzopen.c (ft_lzwstate_get_code): Move check into conditional clause. 2016-08-16 Werner Lemberg <wl@gnu.org> [lzw] Avoid invalid left shift. Reported as https://bugzilla.mozilla.org/show_bug.cgi?id=1295366 * src/lzw/ftzopen.c (ft_lzwstate_get_code): Limit `num_bits'. 2016-08-16 Werner Lemberg <wl@gnu.org> [lzw] Avoid buffer overrun. Reported as https://bugzilla.mozilla.org/show_bug.cgi?id=1273283 * src/lzw/ftzopen.c (ft_lzwstate_refill): Ensure `buf_size' doesn't underflow. 2016-08-16 Werner Lemberg <wl@gnu.org> [truetype] Fix compiler warning. * src/truetype/ttgload.c (load_truetype_glyph): Add cast. 2016-08-13 Werner Lemberg <wl@gnu.org> [winfonts] Avoid zero bitmap width and height. Reported as https://bugzilla.mozilla.org/show_bug.cgi?id=1272173 * src/winfonts/winfnt.c (FNT_Face_Init): Check zero pixel height. (FNT_Load_Glyph): Check for zero pitch. 2016-08-11 Alexei Podtelezhnikov <apodtele@gmail.com> * src/truetype/ttinterp.c (Pop_Push_Count): Revert changes. 2016-08-11 Alexei Podtelezhnikov <apodtele@gmail.com> * src/truetype/ttinterp.c (TT_RunIns): Minor and formatting. 2016-08-11 Alexei Podtelezhnikov <apodtele@gmail.com> * src/truetype/ttinterp.c (Pop_Push_Count): Fix some entries. 2016-08-10 Peter Klotz <Peter.Klotz@ith-icoserve.com> * src/smooth/ftgrays.c (gray_hline): Fix uninitialized access. 2016-08-10 Werner Lemberg <wl@gnu.org> [sfnt] Use correct type for `italicAngle' field (#48732). * src/sfnt/ttload.c (tt_face_load_post): Fix types. 2016-08-06 Jon Spencer <jon@jonspencer.ca> [sfnt] Fix `FT_Get_Advance' for bitmap strikes. `FT_Get_Advance' returns 0 for bitmap fonts. It first gets the advance value from the font table and then scales it by the `font->size->metrics->x_scale' field. But `FT_Select_Size' doesn't set that value for bitmap fonts and the advance gets scaled to zero. Taken from https://github.com/behdad/harfbuzz/issues/252 * src/sfnt/ttsbit.c (tt_face_load_strike_metrics) <TT_SBIT_TABLE_TYPE_EBLC>: Set scale values. 2016-08-06 Behdad Esfahbod <behdad@behdad.org> [truetype] Fix GX variation handling of composites. * src/truetype/ttgload.c (load_truetype_glyph) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: Check `ARGS_ARE_XY_VALUES' flag. 2016-08-05 Alexei Podtelezhnikov <apodtele@gmail.com> [smooth] Minor refactoring. * src/smooth/ftgrays.c (gray_render_scanline, gray_render_line): Updated. 2016-07-29 Werner Lemberg <wl@gnu.org> [sfnt, truetype] Don't abort on invalid `maxComponentDepth'. Since 2016-05-16 we detect infinite recursion directly. * src/sfnt/ttload.c (tt_face_load_maxp): Don't adjust `maxComponentDepth'. * src/truetype/ttgload.c (load_truetype_glyph): Don't abort if `maxComponentDepth' is not valid. Instead, simply adjust its value and emit a tracing message. 2016-07-26 Werner Lemberg <wl@gnu.org> * src/autofit/aflatin.c (af_latin_metrics_scale_dim): Minor. No functional change. 2016-07-22 Hin-Tak Leung <htl10@users.sourceforge.net> [truetype] Record the end of IDEFs. To match the logic in FDEF. The value of the end is only used for bound-checking in `Ins_JMPR', so it may not have been obvious that it was not recorded. Tested (as part of Font Validator 2.0) all the fonts on Fedora and did not see any change. * src/truetype/ttinterp.c (Ins_IDEF): Updated. 2016-07-19 Werner Lemberg <wl@gnu.org> [truetype] Sanitizer fix, second try. * src/truetype/ttgxvar.c (ft_var_readpackedpoints): Fix boundary tests and use only one slot more. 2016-07-19 Werner Lemberg <wl@gnu.org> [truetype] Sanitizer fix. * src/truetype/ttgxvar.c (ft_var_readpackedpoints): Increase array to fix nested loops. 2016-07-18 Werner Lemberg <wl@gnu.org> [truetype] Make GETDATA work only for GX fonts. * src/truetype/ttinterp.c (opcode_name): Updated. (Ins_GETDATA): Only define for `TT_CONFIG_OPTION_GX_VAR_SUPPORT'. (TT_RunIns): Updated. 2016-07-17 Werner Lemberg <wl@gnu.org> [truetype] Add support for Apple's GETDATA[], opcode 0x92 bytecode instruction. It always returns 17, and we have absolutely no idea what it is good for... * src/truetype/ttinterp.c (Pop_Push_Count, opcode_name): Updated. (Ins_GETDATA): New function. (TT_RunIns): Add it. 2016-07-16 Werner Lemberg <wl@gnu.org> [truetype] Add bytecode support for GX variation fonts. This commit implements undocumented (but confirmed) stuff from Apple's old bytecode engine. GETVARIATION[], opcode 0x91 This opcode pushes normalized variation coordinates for all axes onto the stack (in 2.14 format). Coordinate of first axis gets pushed first. GETINFO[], selector bit 3 If GX variation support is enabled, bit 10 of the result is set to 1. * src/truetype/ttinterp.c: Include FT_MULTIPLE_MASTERS_H. (opcode_name) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: Updated. (Ins_GETINFO) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: Handle selector bit 3, checking support for variation glyph hinting. (Ins_GETVARIATION) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: New function to implement opcode 0x91. (TT_RunIns) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: Handle opcode 0x91. 2016-07-16 Werner Lemberg <wl@gnu.org> [truetype] Fix GETINFO bytecode instruction. * src/truetype/ttinterp.c (Ins_GETINFO): Fix return value for stretching information. 2016-07-16 Behdad Esfahbod <behdad@behdad.org> [truetype] Make all glyphs in `Zycon' GX font work. * src/truetype/ttgxvar.c (ft_var_readpackedpoints): Fix boundary tests. 2016-07-16 Werner Lemberg <wl@gnu.org> [truetype] Fix GX delta tracing. * src/truetype/ttgxvar.c (TT_Vary_Apply_Glyph_Deltas): Trace relative point movements. 2016-07-16 Behdad Esfahbod <behdad@behdad.org> [truetype] More fixes for GX. This finally fixes the rendering of the cyclist and the lizard in the `Zycon' font. * src/truetype/ttgxvar.c (ft_var_readpackedpoints): `first' point index is always cumulative. (tt_handle_deltas): Rename to... (tt_interpolate_deltas): ... This. Add new parameter for output point array. Update caller. (TT_Vary_Apply_Glyph_Deltas): Add `points_out' array; it now holds the intermediate results of `tt_interpolate_deltas' that are to be added to `outline->points'. 2016-07-15 Werner Lemberg <wl@gnu.org> * src/autofit/aflatin.c (af_latin_hints_compute_segments): Thinko. `max_pos' is always larger than `min_pos' so `FT_ABS' is not needed. Reported by Alexei. 2016-07-16 Nikolaus Waxweiler <madigens@gmail.com> * src/truetype/ttinterp.c (Ins_MIRP): Fix copy-and-paste error. Problem reported by Hin-Tak Leung. 2016-07-15 Werner Lemberg <wl@gnu.org> [autofit] Update and improve segment and edge tracing. * src/autofit/afhints.c (af_glyph_hints_dump_segments): Trace `delta' also. Don't show first point of segment as a replacement for `pos'; this is (a) misleading, since the difference to `pos' can be almost arbitrarily large in corner cases, and (b) it is better to have all segment data in font units instead of a single value given in output space coordinates. Improve layout. (af_glyph_hints_dump_edges): Show px->units and units->px conversion values for convenience. Improve layout. 2016-07-15 Werner Lemberg <wl@gnu.org> [autofit] For edges, reject segments wider than 1px (#41334). * src/autofit/afhints.h (AF_SegmentRec): New member `delta'. * src/autofit/aflatin.c (af_latin_hints_compute_segments): Compute `delta'. (af_latin_hints_compute_edges): Reject segments with a delta larger than 0.5px. 2016-07-14 Werner Lemberg <wl@gnu.org> * include/freetype/freetype.h (FT_IS_NAMED_INSTANCE): New macro. 2016-07-14 Werner Lemberg <wl@gnu.org> [sfnt] Fix `face_index' value in `FT_Face' for named instances. * src/sfnt/sfobjs.c (sfnt_init_face): Don't strip off higher 16bits. 2016-07-14 Werner Lemberg <wl@gnu.org> * src/truetype/ttgxvar.c (TT_Vary_Apply_Glyph_Deltas): Fix tracing. 2016-07-14 Behdad Esfahbod <behdad@behdad.org> [truetype] Fix gxvar delta interpolation. The coordinates of the base font should be used for interpolation purposes, NOT the current points (i.e., the result of accumulation of previous deltas). * src/truetype/ttgxvar.c (TT_Vary_Apply_Glyph_Deltas): Initialize `points_org' before looping over all tuples. ---------------------------------------------------------------------------- Copyright (C) 2016-2022 by David Turner, Robert Wilhelm, and Werner Lemberg.

2017-09-16 Werner Lemberg <wl@gnu.org> * Version 2.8.1 released. ========================= Tag sources with `VER-2-8-1'. * docs/VERSION.TXT: Add entry for version 2.8.1. * docs/CHANGES: Updated. * README, Jamfile (RefDoc), builds/windows/vc2005/freetype.vcproj, builds/windows/vc2005/index.html, builds/windows/vc2008/freetype.vcproj, builds/windows/vc2008/index.html, builds/windows/vc2010/freetype.vcxproj, builds/windows/vc2010/index.html, builds/windows/visualc/freetype.dsp, builds/windows/visualc/freetype.vcproj, builds/windows/visualc/index.html, builds/windows/visualce/freetype.dsp, builds/windows/visualce/freetype.vcproj, builds/windows/visualce/index.html, builds/wince/vc2005-ce/freetype.vcproj, builds/wince/vc2005-ce/index.html, builds/wince/vc2008-ce/freetype.vcproj, builds/wince/vc2008-ce/index.html: s/2.8/2.8.1/, s/28/281/. * include/freetype/freetype.h (FREETYPE_PATCH): Set to 1. * builds/unix/configure.raw (version_info): Set to 21:0:15. * CMakeLists.txt (VERSION_PATCH): Set to 1. 2017-09-13 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> [sfnt] lowest gcc for vectors (e1d0249e) is changed to 4.7. __builtin_shuffle() was introduced in gcc-4.7. The lowest gcc to enable vector operation is delayed from 4.6 to 4.7. * src/sfnt/pngshim.c (premultiply_data): Fix cpp-macro to enable the vector operation, to change the lowest gcc version from 4.6 to 4.7. 2017-09-13 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> [cache] Fix a possible overflow by signed integer comparison. Improve the code by 5d3ff05615dda6d1325ed612381a17a0df04c975 , issues are found by Behdad Esfahbod and Werner Lemberg. * src/cache/ftcbasic.c (FTC_ImageCache_Lookup): Replace a subtraction to check higher bit by a bit operation, and cpp-conditionalize for appropriate systems. Add better documentation to the comment. (FTC_ImageCache_LookupScaler): Ditto. (FTC_SBitCache_Lookup): Ditto. (FTC_SBitCache_LookupScaler): Ditto. 2017-09-13 Werner Lemberg <wl@gnu.org> [autofit] Really fix #41334 (#52000). * src/autofit/aflatin.c (af_latin_hints_compute_segments): Set `segment->delta' everywhere. 2017-09-12 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> [autofit, sfnt] Fix for `make multi'. * src/autofit/afshaper.c: Include FT_ADVANCE_H, to use FT_Get_Advance() in it. * src/sfnt/ttcmap.c: Include FT_SERVICE_POSTSCRIPT_CMAPS_H to use PS_Unicodes in it, also include `ttpost.h' to use tt_face_get_ps_name() in it. 2017-09-11 Azzuro <azzuro@team-mediaportal.com> [build] Improve builds with different MS Visual Studio versions. * builds/windows/vc2010/freetype.vcxproj: Switch platform toolset according to the Visual Studio version. 2017-09-11 Werner Lemberg <wl@gnu.org> * src/sfnt/ttkern.c (tt_face_load_kern): Reject format 2 tables. Reported by Behdad. 2017-09-09 Werner Lemberg <wl@gnu.org> [autofit] Improve communication with ftgrid. * src/autofit/afhints.c (af_glyph_hints_get_segment_offset): Provide values in font units. 2017-09-08 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> [base] Remove a check for resource ID in the resource fork driver. LastResort.dfont has a marginal resource ID 0xFFFF for sfnt resource. Inside Macintosh: More Macintosh Toolbox, `Resource IDs' (1-46), tells that some IDs are reserved and should not be used. FreeType2 just uses resource ID to sort the fragmented resource. To accept the marginal fonts, the checking is removed. * src/base/ftrfork.c (FT_Raccess_Get_DataOffsets): Remove res_id validity check, fix a trace message format. 2017-09-08 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> [sfnt, truetype] Register the tags for marginal fonts. The first 32bit of standard TrueType variants is 0x00010000, `OTTO', `ttcf', `true' or `typ1'. 2 marginal dfonts on legacy Mac OS X, Keyboard.dfont and LastResort.dfont, have the sfnt resources starting 0xA5 followed by `kbd' or `lst'. Considering the following data could be parsed as conventional TrueType fonts, the header checking is updated to allow these tags. It seems that recent Mac OS X has already switched to normal TTF for these fonts. See the discussion at http://u88.n24.queensu.ca/exiftool/forum/index.php?topic=3931.0 * include/freetype/tttags.h (TTAG_0xA5kbd, TTAG_0xA5lst): New header tags for Keyboard.dfont and LastResort.dfont. * src/sfnt/sfobjs.c (sfnt_open_font): Accept the sfnt resource starts with TTAG_0xA5kbd or TTAG_0xA5lst. * src/truetype/ttobjs.c (tt_face_init): Accept the face with the format tag is TTAG_0xA5kbd or TTAG_0xA5lst. 2017-09-05 Werner Lemberg <wl@gnu.org> Fix multiple calls of `FT_Bitmap_Convert'. The documentation of `FT_Bitmap_Convert' says that multiple calls do proper reallocation of the target FT_Bitmap object. However, this failed for the sequence non-empty bitmap empty bitmap non-empty bitmap Reason was that `FT_Bitmap_Convert' only reallocated the bitmap buffer if it became too small; it didn't make the buffer smaller. For an empty bitmap following a non-empty one, only the buffer dimension got set to zero, without deallocation. If the next call was a non-empty buffer again, an assertion in `ft_mem_qrealloc' was triggered. * src/base/ftbitmap.c (FT_Bitmap_Convert): Always reallocate target buffer to the correct size. * docs/CHANGES: Document it. 2017-09-05 Werner Lemberg <wl@gnu.org> [bdf] Fix size and resolution handling. * src/bdf/bdfdrivr.c (BDF_Face_Init): Use `SIZE' values if `POINT_SIZE', `RESOLUTION_X', or `RESOLUTION_Y' properties are missing. * docs/CHANGES: Document it. 2017-08-25 Alexei Podtelezhnikov <apodtele@gmail.com> Swap `ALLOC_MULT' arguments (#51833). * src/base/ftbitmap.c (ft_bitmap_assure_buffer): Updated. * src/winfonts/winfnt.c (FNT_Load_Glyph): Updated. * src/raster/ftrend1.c (ft_raster1_render): Updated. 2017-08-23 Werner Lemberg <wl@gnu.org> [sfnt] Fix clang compilation (#51788). * src/sfnt/pngshim.c (premultiply_data): Use vectors instead of scalars. (vector_shuffle): New macro to take care of a different built-in function name on clang. 2017-08-22 Werner Lemberg <wl@gnu.org> [base] Don't zero out allocated memory twice (#51816). Patch applied from bug report. * src/base/ftutil.c (ft_mem_qrealloc): Use low-level allocation to avoid unnecessary overhead. 2017-08-22 Werner Lemberg <wl@gnu.org> [truetype] Integer overflow. Changes triggered by https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=3107 * src/truetype/ttinterp.c (Ins_MDRP, Ins_MIRP, Ins_ALIGNPTS): Use NEG_LONG. 2017-08-17 Alexei Podtelezhnikov <apodtele@gmail.com> [sfnt] Avoid synthetic unicode for symbol fonts with PUA. Reported as https://bugs.chromium.org/p/chromium/issues/detail?id=754574 * src/sfnt/sfobjs.c (sfnt_load_face): Check for FT_ENCODING_MS_SYMBOL. 2017-08-16 Werner Lemberg <wl@gnu.org> * src/sfnt/pngshim.c (premultiply_data): Fix compiler warnings. 2017-08-15 Behdad Esfahbod <behdad@behdad.org> [sfnt] Speed up PNG image loading. This reduces the overhead of `premultiply_data' by 60%. * src/sfnt/pngshim.c (premultiply_data): Provide code which uses gcc's (and clang's) `vector_byte' attribute to process 4 pixels at a time. 2017-08-11 Werner Lemberg <wl@gnu.org> [sfnt, truetype] Improve handling of missing sbits. Requested by Behdad. Modern bitmap-only SFNTs like `NotoColorEmoji.ttf' don't contain entries in the bitmap strike(s) for empty glyphs. Instead, they rely that a space glyph gets created from the font's metrics data. This commit makes FreeType behave accordingly. * include/freetype/fterrdef.h (FT_Err_Missing_Bitmap): New error code. * src/sfnt/ttsbit.c (tt_sbit_decoder_load_image): Change error codes to make a distinction between a missing bitmap in a composite and a simple missing bitmap. * src/truetype/ttgload.c (TT_Load_Glyph): For a missing bitmap (in a bitmap-only font), synthesize an empty bitmap glyph if metrics are available. 2017-08-10 Werner Lemberg <wl@gnu.org> [base] Minor API improvement for default variation axis setting. * src/base/ftmm.c (FT_Set_MM_Design_Coordinates, FT_Set_Var_Design_Coordinates, FT_Set_MM_Blend_Coordinates, FT_Set_Var_Blend_Coordinates): Allow coords==NULL if num_coords==0. * docs/CHANGES: Updated. 2017-08-08 Werner Lemberg <wl@gnu.org> [psnames] Really fix issue #49949. We now use a separate preprocessor macro to handle both definition and declaration of the glyph name arrays. * src/psnames/psmodule.c (DEFINE_PS_TABLE_DATA): New macro. * src/tools/glnames.py (StringTable::dump, StringTable::dump_sublist): Use `DEFINE_PS_TABLE_DATA'. (dump_encoding): Ditto. (main): Use `wb' mode for writing the output file, which works on Windows also. * src/psnames/pstables.h: Regenerated. 2017-08-08 Alexei Podtelezhnikov <apodtele@gmail.com> [smooth] Harmony LCD rendering. This is a new technology for LCD-optimized rendering. It capitalizes on the fact that each color channel grid is shifted by a third of a pixel. Therefore it is logical to render 3 separate monochrome bitmaps shifting the outline by 1/3 pixel, and then combine them. Importantly, the resulting output does not require additional LCD filtering. * src/smooth/ftsmooth.c (ft_smooth_render_generic) [!FT_CONFIG_OPTION_SUBPIXEL_RENDERING]: Implement new LCD-optimized rendering. * include/freetype/ftlcdfil.h, include/freetype/freetype.h, include/freetype/config/ftoption.h, devel/ftoption.h: Updated documentation. 2017-08-08 Alexei Podtelezhnikov <apodtele@gmail.com> * src/smooth/ftsmooth.c (ft_smooth_render_generic): Clean up. 2017-08-08 Alexei Podtelezhnikov <apodtele@gmail.com> * src/sfnt/ttpost.c (format): Use otspec-compliant versions. 2017-08-05 Werner Lemberg <wl@gnu.org> [truetype] Integer overflow. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=2868 * src/truetype/ttinterp.c (Ins_ALIGNRP): Use NEG_LONG. 2017-08-05 Werner Lemberg <wl@gnu.org> [base, truetype] New function `FT_Get_Var_Axis_Flags'. The reserved `flags' field got a value in OpenType version 1.8.2; unfortunately, the public `FT_Var_Axis' structure misses the corresponding element. Since we can't add a new field, we add an access function. * src/base/ftmm.c (FT_Get_Var_Axis_Flags): New function. * include/freetype/ftmm.h (FT_VAR_AXIS_FLAG_HIDDEN): New macro. Updated. * src/truetype/ttgxvar.c (TT_Get_MM_Var): Increase allocated memory of `mmvar' to hold axis flags. Fill the axis flags array. * docs/CHANGES: Updated. 2017-08-03 Nikolaus Waxweiler <madigens@gmail.com> [truetype] Fix metrics of B/W hinting in v40 mode. Phantom points are now saved outside v40 backwards compatibility mode. This fixes the jumping glyphs when switching between v35 and v40 monochrome mode. * src/truetype/ttgload.c (TT_Hint_Glyph): Fix inversed bool logic. 2017-08-03 Nikolaus Waxweiler <madigens@gmail.com> [truetype] Do not set any ClearType flags in v40 monochrome mode. This fixes weird behavior of instructions that resulted in rendering differences between v35 and v40 in monochrome mode, e.g., in `timesbi.ttf'. * src/truetype/ttinterp.c (Ins_GETINFO) [TT_SUPPORT_SUBPIXEL_HINTING_MINIMAL]: Check `subpixel_hinting_lean'. 2017-08-01 Werner Lemberg <wl@gnu.org> * src/truetype/ttgxvar.c (TT_Get_MM_Var): Fix thinko. 2017-08-01 Behdad Esfahbod <behdad@behdad.org> [truetype] Fix loading of named instances. * src/truetype/ttgxvar.c (TT_Get_MM_Var): Preserve file position while loading the `avar' table. 2017-08-01 Werner Lemberg <wl@gnu.org> [sfnt, truetype] Minor adjustments for OpenType 1.8.2. * src/sfnt/sfobjs.c (sfnt_load_face): The units per EM value has now (tighter) limits. * src/truetype/ttgload.c (load_truetype_glyph): The new OpenType version explicitly allows all negative values for the number of contours if we have a composite glyph (this is for better backwards compatibility I guess), but it still recommends value -1. 2017-07-26 Werner Lemberg <wl@gnu.org> [cff] Integer overflow. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=2738 * src/cff/cf2hints.c (cf2_glyphpath_computeOffset, cf2_glyphpath_curveTo): Use ADD_INT32. 2017-07-13 Werner Lemberg <wl@gnu.org> [base] Fix memory leak. Reported as https://bugs.chromium.org/p/chromium/issues/detail?id=738362 * src/base/ftglyph.c (FT_Get_Glyph): Do proper deallocation in case of error. 2017-07-12 Werner Lemberg <wl@gnu.org> [base] Integer overflow. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=2573 * src/base/ftobjs.c (ft_glyphslot_grid_fit_metrics): Use FT_PIX_CEIL_LONG and FT_PIX_ROUND_LONG. 2017-07-12 Werner Lemberg <wl@gnu.org> * src/truetype/ttpload.c (tt_face_get_location): Off-by-one typo. Also improve tracing message. Problem reported as https://bugs.chromium.org/p/chromium/issues/detail?id=738919 2017-07-07 Werner Lemberg <wl@gnu.org> [cff] Integer overflow. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=2517 * src/cff/cf2blues.c (cf2_blues_capture): Use SUB_INT32. 2017-07-05 Werner Lemberg <wl@gnu.org> * src/sfnt/ttcmap.c (tt_cmap_unicode_class_rec): Fix warning. 2017-07-05 Werner Lemberg <wl@gnu.org> * src/truetype/ttgxvar.c (FT_Stream_SeekSet): Fix warning (#51395). 2017-07-04 Werner Lemberg <wl@gnu.org> [truetype] Prevent address overflow (#51365). * src/truetype/ttgxvar.c (FT_Stream_SeekSet): Add guard. 2017-07-03 Alexei Podtelezhnikov <apodtele@gmail.com> * src/base/ftlcdfil.c (ft_lcd_filter_fir): Improve code. 2017-07-03 Werner Lemberg <wl@gnu.org> [truetype] Integer overflow. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=2455 * src/truetype/ttinterp.c (Ins_SCFS): Use SUB_LONG. 2017-07-01 Alexei Podtelezhnikov <apodtele@gmail.com> * src/sfnt/sfobjs.c (sfnt_load_face): Ignore No_Unicode_Glyph_Name. 2017-06-28 Ben Wagner <bungeman@google.com> Avoid Microsoft compiler warnings (#51331).

This commit (mainly for 32bit CPUs) is the first of a series of similar commits to handle known integer overflows. Basically, all of them are harmless, since they affect rendering of glyphs only, not posing security threats. It is expected that fuzzying will show up more overflows, to be fixed in due course. The idea is to mark places where overflows can occur, using macros that simply cast to unsigned integers, because overflow arithmetic is well defined in this case. Doing so suppresses run-time errors of sanitizers without adding computational overhead. * include/freetype/internal/ftcalc.h (OVERFLOW_ADD_INT, OVERFLOW_SUB_INT, OVERFLOW_MUL_INT, OVERFLOW_ADD_LONG, OVERFLOW_SUB_LONG, OVERFLOW_MUL_LONG): New macros. * src/base/ftcalc.c (FT_RoundFix, FT_CeilFix, FT_Matrix_Multiply, FT_Matrix_Multiply_Scaled, FT_Vector_Transform_Scaled, ft_corner_orientation): Use new macros. * src/base/ftoutln.c (FT_Outline_Get_Orientation): Use new macros. 2017-05-28 Werner Lemberg <wl@gnu.org> * include/freetype/internal/ftcalc.h (FLOAT_TO_FIXED): Remove.

This mode uses fractional advance widths and doesn't scale glyphs horizontally, only applying vertical scaling and hinting. At the same time, the behaviour of the `light' auto-hinter gets restored for backward compatibility: Both vertical and horizontal scaling is again based on rounded metrics values (this was changed in a commit from 2017-03-30 as a side effect). To be more precise, the behaviour is restored for TrueType fonts only; for other font formats like Type 1, this is a new feature of the `light' hinting mode. * include/freetype/freetype.h (FT_LOAD_TARGET_SLIGHT): New macro.

Problem reported as https://github.com/google/fonts/issues/632 The font in question (Nunito) has values 705 and 713 for the reference and overshoot values, respectively, of the first blue zone. Blue zone 2, however, has value 710 for both the reference and overshoot. At 12ppem, reference and overshoot of blue zone 0 becomes 8px, while blue zone 2 becomes 9px. A peculiarity of this font is that the tops of isolated vertical stems like `N' have a slight overshoot also. The auto-hinter tries to find the nearest blue zone using the *original* coordinates. For vertical stems, this is value 713. For normal horizontal tops like in character `E', this is value 710. Since value 713 is mapped to 8px but value 710 to 9px, `N' and similar characters are one pixel higher than `E', which looks very bad. This commit sanitizes blue zones to avoid such a behaviour. * src/autofit/aflatin.c (af_latin_sort_blue): New function. (af_latin_metrics_init_blues): Sort blue values and remove overlaps. 2017-02-12 Alexei Podtelezhnikov <apodtele@gmail.com> * src/smooth/ftgrays.c (gray_sweep): Improve code. 2017-02-06 Werner Lemberg <wl@gnu.org> [truetype] Implement `VVAR' table support. * src/truetype/ttgxvar.h (GX_HVarTable): Renamed to...

The number of lowercase characters for computing the top flat blue zone value was too small (in most cases only `x' and `z'). If one of the two characters has a large serif, say, it can happen that FreeType must select between two different values, having a 50% chance to use the wrong one. As a result, rendering at larger PPEM values could yield uneven lowercase glyph heights.

Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=7652 * src/truetype/ttinterp.c (Ins_MDAP): Use SUB_LONG. 2018-04-14 Werner Lemberg <wl@gnu.org> [autofit] Update to Unicode 11.0.0.

This brings up the minimum required CMake version to 2.8.12. The installation paths follow the GNU defaults now, e.g. installing on a 64 bit host will place binaries into the lib64/ folder on e.g. Fedora. Symbols are hidden by default (e.g. `-fvisibility=hidden' on GCC). CMake will no longer look for a C++ compiler. Library and .so version now match the Autotools build. Comments in the build file and informational messages now use platform agnostic example commands. ftoption.h and ftconfig.h are written directly without a redundant `-new' copy. External dependencies are expressed as option()s and will turn up as such in cmake-gui. Internal: Properties such as dependencies and include directories are now privately set on the freetype library instead of globally. The CPack definitions have been cleaned up, the `make dist' has been removed. Source packages generated with CPack don't contain Autotools files and aren't used by the maintainers anyway. On Windows, src/base/ftver.rc is compiled to decorate the library with version and copyright information.

According to the CFF specification, charstrings can have up to 96 stem hints. Due to hint replacement routines in Type 1 charstrings, some glyphs are rejected by the Adobe engine, which implements the above limit. This fix turns off hinting for such glyphs. * src/psaux/pshints.c (cf2_hintmap_build): Reset the error from calling `cf2_hintmask_setAll' on a problematic Type 1 charstring and turn off hinting. 2018-01-06 Werner Lemberg <wl@gnu.org> Add `FT_Done_MM_Var'.

Simplify code of test that checks cpp's computation of bit length (the test previously created an empty `ftoption.h' file and deleted it immediately afterwards); without this change, it can happen on my GNU/Linux box that `configure's execution of `config.status' doesn't create `ftoption.h' (no idea why this happens). * builds/unix/install.mk (install): Install `builds/unix/ftoption.h'. * builds/unix/unix-def.in (DISTCLEAN): Updated. * builds/unix/.gitignore: Updated. 2017-11-23 Tor Andersson <tor.andersson@artifex.com> Silence unused function warnings (#52465).

(#52466) Glyph advance widths were being written to the new `PS_Decoder' but not saved to the underlying format specific decoder. This caused pure CFF fonts to have bad advance width. * include/freetype/internal/psaux.h (PS_Decoder): Change `glyph_width' field to pointer.

Since Ewald Hew factored the Adobe hinting engine out of the CFF driver code, we can now use it on Type 1 (and CID) font formats, as both have the same hinting philosophy. This change activates the Adobe hinter when in LIGHT mode, and therefore always unless explicitly asking for the auto-hinter. This makes LIGHT behavior consistent with CFF fonts. As of this commit, the hinting engine table looks as follows.

(#52251) The interpreter in Type 1 mode rewinds the charstring after collecting all hints for building the initial hintmap (commit d52dd7f). However, some charstrings use `endchar' in a final subroutine call, rewinding to the start of that subroutine, and only a small section of the actual glyph is drawn. * src/psaux/psintrp.c (cf2_interpT2CharString) <cf2_cmdENDCHAR>: Ensure we are on the top level charstring before rewinding. 2017-11-03 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> [truetype] Add more tricky fonts.

We used to split large glyphs into horizontal bands and continue bisecting them still horizontally if that was not enough. This is guaranteed to fail when a single scanline cannot fit into the rendering memory pool. Now we bisect the bands vertically so that the smallest unit is a column of the band height, which is guranteed to fit into memory. * src/smooth/ftgrays.c (gray_convert_glyph): Implement it. 2017-10-20 Alexei Podtelezhnikov <apodtele@gmail.com> [smooth] Improve complex rendering at high ppem.

(cf2_interpT2CharString): Remove unused variables. <cf2_cmdHMOVETO, cf2_cmdVMOVETO, cf2_cmdRMOVETO>: `hsbw' or `sbw' must be the first operation in a Type 1 charstring. <cf2_cmdHSBW, cf2_escSBW>: Fix data access and add correction for left sidebearing. 2017-09-25 Ewald Hew <ewaldhew@gmail.com> [psaux] Extend Adobe interpreter (setcurrentpoint). * src/psaux/psintrp.c (cf2_interpT2CharString) <cf2_escSETCURRENTPT>: Fix stack access. 2017-09-25 Ewald Hew <ewaldhew@gmail.com> [psaux] Extend Adobe interpreter (closepath). * src/psaux/psintrp.c (cf2_interpT2CharString) <c2f_cmdCLOSEPATH>: Use the right builder function. We can use the `haveWidth' boolean already present, instead of implementing `parse_state'. 2017-09-25 Ewald Hew <ewaldhew@gmail.com> [psaux] Add Type 1 operations to Adobe CFF interpreter. The following Type 1 specific ops have been added (copied from `t1decode'): closepath vstem3 hstem3 seac sbw callothersubr pop setcurrentpoint hsbw The following require a Type 1 mode, because of differences in specification: hstem vstem vmoveto callsubr div rmoveto hmoveto Numbers The subsequent commits will implement these changes and adapt accesses of data and objects to the new interpreter. NOTE: Will not compile in the meantime! * src/psaux/psintrp.c: Add opcodes to enum. (cf2_interpT2CharString): Copy relevant code over from `t1_decoder_parse_charstrings' (in `t1decode.c'). 2017-09-25 Ewald Hew <ewaldhew@gmail.com> [type1] Fixes for rendering. The Type 1 advance width calculation passes null for glyph slot, etc, which can cause null pointer access in the new interpreter. Fall back to the old one for now. Fix the large glyph retry code and ensure hinting and scaling flags are set properly. * src/type1/t1gload.c (T1_Parse_Glyph_And_Get_Char_String): Add a check for metrics_only. Set the `force_scaling' flag. (T1_Parse_Glyph): Updated. (T1_Load_Glyph): Add `hinting' and `scaled' flags. 2017-09-25 Ewald Hew <ewaldhew@gmail.com> [psaux] Add missing objects (2/2). Synthesize a `SubFont' object for Type 1 fonts. This is used in the interpreter to access Private dict data, which are stored in different places for Type 1 and CFF. This allows the same data to be used in either mode. * src/psaux/psobjs.c (t1_make_subfont): New procedure to copy required values to a dummy `CFF_SubFont' object. This is similar to `cff_make_private_dict'. * src/psaux/psobjs.h: Add the new declaration. * include/freetype/internal/psaux.h, src/psaux/psauxmod.c: Ditto. Add this to the PSAux Service for future use with CID fonts. * src/type1/t1gload.c: Include FT_INTERNAL_CFF_TYPES_H. (T1_Parse_Glyph_And_Get_Char_String): Add the call. 2017-09-25 Ewald Hew <ewaldhew@gmail.com> [psaux] Add missing objects for Type 1 (1/2). Move `CF2_Font' instance to `PS_Decoder'. This is the context for the interpreter and since it is currently stored in `CFF_Font', is unavailable in Type 1 mode. * include/freetype/internal/psaux.h (T1_Decoder, PS_Decoder): New `cf2_instance' field. * src/psaux/psdecode.c (ps_decoder_init): Copy `cf2_instance' to `PS_Decoder'. * src/psaux/t1decode.c (t1_decoder_done): Add finalization code. * src/psaux/psft.c (cf2_decoder_parse_charstrings): Update accesses. 2017-09-25 Ewald Hew <ewaldhew@gmail.com> Allow `type1' module to use the Adobe engine. Add the callback and some conditionals to switch between the two engines. * include/freetype/internal/psaux.h (T1_Decoder_FuncsRec): Change function declarations. * src/psaux/psauxmod.c (T1_Decoder_FuncsRec): Register the callbacks. * src/psaux/psobjs.c (ps_builder_add_point): Add conditionals for number conversion. * src/type1/t1gload.c (T1_Parse_Glyph_And_Get_Char_String): Add code to choose which renderer to use. * src/cid/cidgload.c (cid_load_glyph): Update call. * src/base/ftobjs.c, src/psaux/psobjs.c, src/type1/t1gload.c: Update includes. 2017-09-25 Ewald Hew <ewaldhew@gmail.com> [type1] Add Adobe engine configuration. Use the previously changed PS_Driver in type1 module to store hinting engine configuration. * include/freetype/ftt1drv.h: New file. Duplicate and rename config options from CFF. * include/freetype/config/ftheader.h (FT_TYPE1_DRIVER_H): New macro. * src/type1/t1driver.c (t1_driver_class): Update declaration. * src/type1/t1objs.c: Include FT_TYPE1_DRIVER_H. (T1_Driver_Init): Update code. 2017-09-25 Ewald Hew <ewaldhew@gmail.com> [cff] Move and rename `CFF_Driver'. This is so that we can use the same hinting engine parameters for Type 1. * include/freetype/internal/cffotypes.h (CFF_Driver): Rename and move to... * include/freetype/internal/psaux.h (PS_Driver): ...here. * src/cff/cffdrivr.c, src/cff/cffgload.c, src/cff/cffload.c, src/cff/cffobjs.c, src/cff/cffobjs.h, src/psaux/psft.c, src/psaux/psobjs.c: Update references. 2017-09-25 Ewald Hew <ewaldhew@gmail.com> [psaux, type1] Reorganize object fields. Make some fields more generic, so that we can access them the same way regardless of Type 1 or CFF. * include/freetype/internal/psaux.h (PS_Builder): Change `TT_Face' to `FT_Face'. Remove unused fields. * src/psaux/psft.c: Update all accesses of `PS_Builder.face'. Add some asserts to guard against casting `T1_Face' as `TT_Face'. * src/type1/t1objs.h (T1_GlyphSlot): Reorder fields to follow `CFF_GlyphSlot', so that we can pretend they are the same in the interpreter. * src/psaux/psobjs.c (ps_builder_init, ps_builder_add_point): Updated with above changes. 2017-09-25 Ewald Hew <ewaldhew@gmail.com> [psaux] Prepare for Type 1 mode. Add some checks for Type 1 data passing through. * src/psaux/psfont.h (CF2_Font): Add `isT1' flag. * src/psaux/psfont.c (cf2_font_setup): Skip the variations and blend code which is not applicable for Type 1. * src/psaux/psft.c (cf2_decoder_parse_charstrings): Avoid accessing `decoder->cff' in Type 1 mode.

How FreeType's rasterizer work by David Turner Revised 2007-Feb-01 This file is an attempt to explain the internals of the FreeType rasterizer. The rasterizer is of quite general purpose and could easily be integrated into other programs. I. Introduction II. Rendering Technology 1. Requirements 2. Profiles and Spans a. Sweeping the Shape b. Decomposing Outlines into Profiles c. The Render Pool d. Computing Profiles Extents e. Computing Profiles Coordinates f. Sweeping and Sorting the Spans I. Introduction =============== A rasterizer is a library in charge of converting a vectorial representation of a shape into a bitmap. The FreeType rasterizer has been originally developed to render the glyphs found in TrueType files, made up of segments and second-order Béziers. Meanwhile it has been extended to render third-order Bézier curves also. This document is an explanation of its design and implementation. While these explanations start from the basics, a knowledge of common rasterization techniques is assumed. II. Rendering Technology ======================== 1. Requirements --------------- We assume that all scaling, rotating, hinting, etc., has been already done. The glyph is thus described by a list of points in the device space. - All point coordinates are in the 26.6 fixed float format. The used orientation is: ^ y | reference orientation | *----> x 0 `26.6' means that 26 bits are used for the integer part of a value and 6 bits are used for the fractional part. Consequently, the `distance' between two neighbouring pixels is 64 `units' (1 unit = 1/64th of a pixel). Note that, for the rasterizer, pixel centers are located at integer coordinates. The TrueType bytecode interpreter, however, assumes that the lower left edge of a pixel (which is taken to be a square with a length of 1 unit) has integer coordinates. ^ y ^ y | | | (1,1) | (0.5,0.5) +-----------+ +-----+-----+ | | | | | | | | | | | | | o-----+-----> x | | | (0,0) | | | | | o-----------+-----> x +-----------+ (0,0) (-0.5,-0.5) TrueType bytecode interpreter FreeType rasterizer A pixel line in the target bitmap is called a `scanline'. - A glyph is usually made of several contours, also called `outlines'. A contour is simply a closed curve that delimits an outer or inner region of the glyph. It is described by a series of successive points of the points table. Each point of the glyph has an associated flag that indicates whether it is `on' or `off' the curve. Two successive `on' points indicate a line segment joining the two points. One `off' point amidst two `on' points indicates a second-degree (conic) Bézier parametric arc, defined by these three points (the `off' point being the control point, and the `on' ones the start and end points). Similarly, a third-degree (cubic) Bézier curve is described by four points (two `off' control points between two `on' points). Finally, for second-order curves only, two successive `off' points forces the rasterizer to create, during rendering, an `on' point amidst them, at their exact middle. This greatly facilitates the definition of successive Bézier arcs. The parametric form of a second-order Bézier curve is: P(t) = (1-t)^2*P1 + 2*t*(1-t)*P2 + t^2*P3 (P1 and P3 are the end points, P2 the control point.) The parametric form of a third-order Bézier curve is: P(t) = (1-t)^3*P1 + 3*t*(1-t)^2*P2 + 3*t^2*(1-t)*P3 + t^3*P4 (P1 and P4 are the end points, P2 and P3 the control points.) For both formulae, t is a real number in the range [0..1]. Note that the rasterizer does not use these formulae directly. They exhibit, however, one very useful property of Bézier arcs: Each point of the curve is a weighted average of the control points. As all weights are positive and always sum up to 1, whatever the value of t, each arc point lies within the triangle (polygon) defined by the arc's three (four) control points. In the following, only second-order curves are discussed since rasterization of third-order curves is completely identical. Here some samples for second-order curves. * # on curve * off curve __---__ #-__ _-- -_ --__ _- - --__ # \ --__ # -# Two `on' points Two `on' points and one `off' point between them * # __ Two `on' points with two `off' \ - - points between them. The point \ / \ marked `0' is the middle of the - 0 \ `off' points, and is a `virtual -_ _- # on' point where the curve passes. -- It does not appear in the point * list. 2. Profiles and Spans --------------------- The following is a basic explanation of the _kind_ of computations made by the rasterizer to build a bitmap from a vector representation. Note that the actual implementation is slightly different, due to performance tuning and other factors. However, the following ideas remain in the same category, and are more convenient to understand. a. Sweeping the Shape The best way to fill a shape is to decompose it into a number of simple horizontal segments, then turn them on in the target bitmap. These segments are called `spans'. __---__ _-- -_ _- - - \ / \ / \ | \ __---__ Example: filling a shape _----------_ with spans. _-------------- ----------------\ /-----------------\ This is typically done from the top / \ to the bottom of the shape, in a | | \ movement called a `sweep'. V __---__ _----------_ _-------------- ----------------\ /-----------------\ /-------------------\ |---------------------\ In order to draw a span, the rasterizer must compute its coordinates, which are simply the x coordinates of the shape's contours, taken on the y scanlines. /---/ |---| Note that there are usually /---/ |---| several spans per scanline. | /---/ |---| | /---/_______|---| When rendering this shape to the V /----------------| current scanline y, we must /-----------------| compute the x values of the a /----| |---| points a, b, c, and d. - - - * * - - - - * * - - y - / / b c| |d /---/ |---| /---/ |---| And then turn on the spans a-b /---/ |---| and c-d. /---/_______|---| /----------------| /-----------------| a /----| |---| - - - ####### - - - - ##### - - y - / / b c| |d b. Decomposing Outlines into Profiles For each scanline during the sweep, we need the following information: o The number of spans on the current scanline, given by the number of shape points intersecting the scanline (these are the points a, b, c, and d in the above example). o The x coordinates of these points. x coordinates are computed before the sweep, in a phase called `decomposition' which converts the glyph into *profiles*. Put it simply, a `profile' is a contour's portion that can only be either ascending or descending, i.e., it is monotonic in the vertical direction (we also say y-monotonic). There is no such thing as a horizontal profile, as we shall see. Here are a few examples: this square 1 2 ---->---- is made of two | | | | | | profiles | | ^ v ^ + v | | | | | | | | ----<---- up down this triangle P2 1 2 |\ is made of two | \ ^ | \ \ | \ | | \ \ profiles | \ | | | \ v ^ | \ | | \ | | + \ v | \ | | \ P1 ---___ \ ---___ \ ---_\ ---_ \ <--__ P3 up down A more general contour can be made of more than two profiles: __ ^ / | / ___ / | / | / | / | / | | | / / => | v / / | | | | | | ^ | ^ | |___| | | ^ + | + | + v | | | v | | | | | up | |___________| | down | <-- up down Successive profiles are always joined by horizontal segments that are not part of the profiles themselves. For the rasterizer, a profile is simply an *array* that associates one horizontal *pixel* coordinate to each bitmap *scanline* crossed by the contour's section containing the profile. Note that profiles are *oriented* up or down along the glyph's original flow orientation. In other graphics libraries, profiles are also called `edges' or `edgelists'. c. The Render Pool FreeType has been designed to be able to run well on _very_ light systems, including embedded systems with very few memory. A render pool will be allocated once; the rasterizer uses this pool for all its needs by managing this memory directly in it. The algorithms that are used for profile computation make it possible to use the pool as a simple growing heap. This means that this memory management is actually quite easy and faster than any kind of malloc()/free() combination. Moreover, we'll see later that the rasterizer is able, when dealing with profiles too large and numerous to lie all at once in the render pool, to immediately decompose recursively the rendering process into independent sub-tasks, each taking less memory to be performed (see `sub-banding' below). The render pool doesn't need to be large. A 4KByte pool is enough for nearly all renditions, though nearly 100% slower than a more comfortable 16KByte or 32KByte pool (that was tested with complex glyphs at sizes over 500 pixels). d. Computing Profiles Extents Remember that a profile is an array, associating a _scanline_ to the x pixel coordinate of its intersection with a contour. Though it's not exactly how the FreeType rasterizer works, it is convenient to think that we need a profile's height before allocating it in the pool and computing its coordinates. The profile's height is the number of scanlines crossed by the y-monotonic section of a contour. We thus need to compute these sections from the vectorial description. In order to do that, we are obliged to compute all (local and global) y extrema of the glyph (minima and maxima). P2 For instance, this triangle has only two y-extrema, which are simply |\ | \ P2.y as a vertical maximum | \ P3.y as a vertical minimum | \ | \ P1.y is not a vertical extremum (though | \ it is a horizontal minimum, which we P1 ---___ \ don't need). ---_\ P3 Note that the extrema are expressed in pixel units, not in scanlines. The triangle's height is certainly (P3.y-P2.y+1) pixel units, but its profiles' heights are computed in scanlines. The exact conversion is simple: - min scanline = FLOOR ( min y ) - max scanline = CEILING( max y ) A problem arises with Bézier Arcs. While a segment is always necessarily y-monotonic (i.e., flat, ascending, or descending), which makes extrema computations easy, the ascent of an arc can vary between its control points. P2 * # on curve * off curve __-x--_ _-- -_ P1 _- - A non y-monotonic Bézier arc. # \ - The arc goes from P1 to P3. \ \ P3 # We first need to be able to easily detect non-monotonic arcs, according to their control points. I will state here, without proof, that the monotony condition can be expressed as: P1.y <= P2.y <= P3.y for an ever-ascending arc P1.y >= P2.y >= P3.y for an ever-descending arc with the special case of P1.y = P2.y = P3.y where the arc is said to be `flat'. As you can see, these conditions can be very easily tested. They are, however, extremely important, as any arc that does not satisfy them necessarily contains an extremum. Note also that a monotonic arc can contain an extremum too, which is then one of its `on' points: P1 P2 #---__ * P1P2P3 is ever-descending, but P1 -_ is an y-extremum. - ---_ \ -> \ \ P3 # Let's go back to our previous example: P2 * # on curve * off curve __-x--_ _-- -_ P1 _- - A non-y-monotonic Bézier arc. # \ - Here we have \ P2.y >= P1.y && \ P3 P2.y >= P3.y (!) # We need to compute the vertical maximum of this arc to be able to compute a profile's height (the point marked by an `x'). The arc's equation indicates that a direct computation is possible, but we rely on a different technique, which use will become apparent soon. Bézier arcs have the special property of being very easily decomposed into two sub-arcs, which are themselves Bézier arcs. Moreover, it is easy to prove that there is at most one vertical extremum on each Bézier arc (for second-degree curves; similar conditions can be found for third-order arcs). For instance, the following arc P1P2P3 can be decomposed into two sub-arcs Q1Q2Q3 and R1R2R3: P2 * # on curve * off curve original Bézier arc P1P2P3. __---__ _-- --_ _- -_ - - / \ / \ # # P1 P3 P2 * Q3 Decomposed into two subarcs Q2 R2 Q1Q2Q3 and R1R2R3 * __-#-__ * _-- --_ _- R1 -_ Q1 = P1 R3 = P3 - - Q2 = (P1+P2)/2 R2 = (P2+P3)/2 / \ / \ Q3 = R1 = (Q2+R2)/2 # # Q1 R3 Note that Q2, R2, and Q3=R1 are on a single line which is tangent to the curve. We have then decomposed a non-y-monotonic Bézier curve into two smaller sub-arcs. Note that in the above drawing, both sub-arcs are monotonic, and that the extremum is then Q3=R1. However, in a more general case, only one sub-arc is guaranteed to be monotonic. Getting back to our former example: Q2 * __-x--_ R1 _-- #_ Q1 _- Q3 - R2 # \ * - \ \ R3 # Here, we see that, though Q1Q2Q3 is still non-monotonic, R1R2R3 is ever descending: We thus know that it doesn't contain the extremum. We can then re-subdivide Q1Q2Q3 into two sub-arcs and go on recursively, stopping when we encounter two monotonic subarcs, or when the subarcs become simply too small. We will finally find the vertical extremum. Note that the iterative process of finding an extremum is called `flattening'. e. Computing Profiles Coordinates Once we have the height of each profile, we are able to allocate it in the render pool. The next task is to compute coordinates for each scanline. In the case of segments, the computation is straightforward, using the Euclidean algorithm (also known as Bresenham). However, for Bézier arcs, the job is a little more complicated. We assume that all Béziers that are part of a profile are the result of flattening the curve, which means that they are all y-monotonic (ascending or descending, and never flat). We now have to compute the intersections of arcs with the profile's scanlines. One way is to use a similar scheme to flattening called `stepping'. Consider this arc, going from P1 to --------------------- P3. Suppose that we need to compute its intersections with the drawn scanlines. As already --------------------- mentioned this can be done directly, but the involved * P2 _---# P3 algorithm is far too slow. ------------- _-- -- _- _/ Instead, it is still possible to ---------/----------- use the decomposition property in / the same recursive way, i.e., | subdivide the arc into subarcs ------|-------------- until these get too small to cross | more than one scanline! | -----|--------------- This is very easily done using a | rasterizer-managed stack of | subarcs. # P1 f. Sweeping and Sorting the Spans Once all our profiles have been computed, we begin the sweep to build (and fill) the spans. As both the TrueType and Type 1 specifications use the winding fill rule (but with opposite directions), we place, on each scanline, the present profiles in two separate lists. One list, called the `left' one, only contains ascending profiles, while the other `right' list contains the descending profiles. As each glyph is made of closed curves, a simple geometric property ensures that the two lists contain the same number of elements. Creating spans is thus straightforward: 1. We sort each list in increasing horizontal order. 2. We pair each value of the left list with its corresponding value in the right list. / / | | For example, we have here / / | | four profiles. Two of >/ / | | | them are ascending (1 & 1// / ^ | | | 2 3), while the two others // // 3| | | v are descending (2 & 4). / //4 | | | On the given scanline, a / /< | | the left list is (1,3), - - - *-----* - - - - *---* - - y - and the right one is / / b c| |d (4,2) (sorted). There are then two spans, joining 1 to 4 (i.e. a-b) and 3 to 2 (i.e. c-d)! Sorting doesn't necessarily take much time, as in 99 cases out of 100, the lists' order is kept from one scanline to the next. We can thus implement it with two simple singly-linked lists, sorted by a classic bubble-sort, which takes a minimum amount of time when the lists are already sorted. A previous version of the rasterizer used more elaborate structures, like arrays to perform `faster' sorting. It turned out that this old scheme is not faster than the one described above. Once the spans have been `created', we can simply draw them in the target bitmap. ------------------------------------------------------------------------ Copyright (C) 2003-2022 by David Turner, Robert Wilhelm, and Werner Lemberg.

<code><a href="ft2-base_interface.html#ft_open_face">FT_Open_Face</a></code>. This means that if no font driver is capable of handling the raw compressed file, the library will try to open a bzip2 compressed stream from it and re-open the face with it.</p> <p>The stream implementation is very basic and resets the decompression process each time seeking backwards is needed within the stream, which significantly undermines the performance.</p> <p>This section contains the declaration of Bzip2-specific functions.</p> <h2 id="ft_stream_openbzip2">FT_Stream_OpenBzip2<a class="headerlink" href="#ft_stream_openbzip2" title="Permanent link">¶</a></h2> <p>Defined in FT_BZIP2_H (freetype/ftbzip2.h).</p> <div class = "codehilite"><pre><code> FT_EXPORT( <a href="ft2-basic_types.html#ft_error">FT_Error</a> ) <b>FT_Stream_OpenBzip2</b>( <a href="ft2-system_interface.html#ft_stream">FT_Stream</a> stream, <a href="ft2-system_interface.html#ft_stream">FT_Stream</a> source ); </code></pre></div> <p>Open a new stream to parse bzip2-compressed font files.

Sub-System<a class="headerlink" href="#cache-sub-system" title="Permanent link">¶</a></h1> <h2 id="synopsis">Synopsis<a class="headerlink" href="#synopsis" title="Permanent link">¶</a></h2> <p>This section describes the FreeType 2 cache sub-system, which is used to limit the number of concurrently opened <code><a href="ft2-base_interface.html#ft_face">FT_Face</a></code> and <code><a href="ft2-base_interface.html#ft_size">FT_Size</a></code> objects, as well as caching information like character maps and glyph images while limiting their maximum memory usage.</p> <p>Note that all types and functions begin with the <code>FTC_</code> prefix.</p> <p>The cache is highly portable and thus doesn't know anything about the fonts installed on your system, or how to access them. This implies the following scheme:</p> <p>First, available or installed font faces are uniquely identified by <code><a href="ft2-cache_subsystem.html#ftc_faceid">FTC_FaceID</a></code> values, provided to the cache by the client. Note that the cache only stores and compares these values, and doesn't try to interpret them in any way.</p> <p>Second, the cache calls, only when needed, a client-provided function to convert an <code><a href="ft2-cache_subsystem.html#ftc_faceid">FTC_FaceID</a></code> into a new <code><a href="ft2-base_interface.html#ft_face">FT_Face</a></code> object. The latter is then completely managed by the cache, including its termination through <code><a href="ft2-base_interface.html#ft_done_face">FT_Done_Face</a></code>. To monitor termination of face objects, the finalizer callback in the <code>generic</code> field of the <code><a href="ft2-base_interface.html#ft_face">FT_Face</a></code> object can be used, which might also be used to store the <code><a href="ft2-cache_subsystem.html#ftc_faceid">FTC_FaceID</a></code> of the face.</p> <p>Clients are free to map face IDs to anything else. The most simple usage is to associate them to a (pathname,face_index) pair that is used to call <code><a href="ft2-base_interface.html#ft_new_face">FT_New_Face</a></code>. However, more complex schemes are also possible.</p> <p>Note that for the cache to work correctly, the face ID values must be <strong>persistent</strong>, which means that the contents they point to should not change at runtime, or that their value should not become invalid.</p> <p>If this is unavoidable (e.g., when a font is uninstalled at runtime), you should call <code><a href="ft2-cache_subsystem.html#ftc_manager_removefaceid">FTC_Manager_RemoveFaceID</a></code> as soon as possible, to let the cache get rid of any references to the old <code><a href="ft2-cache_subsystem.html#ftc_faceid">FTC_FaceID</a></code> it may keep internally. Failure to do so will lead to incorrect behaviour or even crashes.</p> <p>To use the cache, start with calling <code><a href="ft2-cache_subsystem.html#ftc_manager_new">FTC_Manager_New</a></code> to create a new <code><a href="ft2-cache_subsystem.html#ftc_manager">FTC_Manager</a></code> object, which models a single cache instance. You can then look up <code><a href="ft2-base_interface.html#ft_face">FT_Face</a></code> and <code><a href="ft2-base_interface.html#ft_size">FT_Size</a></code> objects with <code><a href="ft2-cache_subsystem.html#ftc_manager_lookupface">FTC_Manager_LookupFace</a></code> and <code><a href="ft2-cache_subsystem.html#ftc_manager_lookupsize">FTC_Manager_LookupSize</a></code>, respectively.</p> <p>If you want to use the charmap caching, call <code><a href="ft2-cache_subsystem.html#ftc_cmapcache_new">FTC_CMapCache_New</a></code>, then later use <code><a href="ft2-cache_subsystem.html#ftc_cmapcache_lookup">FTC_CMapCache_Lookup</a></code> to perform the equivalent of <code><a href="ft2-base_interface.html#ft_get_char_index">FT_Get_Char_Index</a></code>, only much faster.</p> <p>If you want to use the <code><a href="ft2-glyph_management.html#ft_glyph">FT_Glyph</a></code> caching, call <code><a href="ft2-cache_subsystem.html#ftc_imagecache_new">FTC_ImageCache_New</a></code>, then later use <code><a href="ft2-cache_subsystem.html#ftc_imagecache_lookup">FTC_ImageCache_Lookup</a></code> to retrieve the corresponding <code><a href="ft2-glyph_management.html#ft_glyph">FT_Glyph</a></code> objects from the cache.</p> <p>If you need lots of small bitmaps, it is much more memory efficient to call <code><a href="ft2-cache_subsystem.html#ftc_sbitcache_new">FTC_SBitCache_New</a></code> followed by <code><a href="ft2-cache_subsystem.html#ftc_sbitcache_lookup">FTC_SBitCache_Lookup</a></code>. This returns <code><a href="ft2-cache_subsystem.html#ftc_sbitrec">FTC_SBitRec</a></code> structures, which are used to store small bitmaps directly. (A small bitmap is one whose metrics and dimensions all fit into 8-bit integers).</p> <p>We hope to also provide a kerning cache in the near future.</p> <h2 id="ftc_manager">FTC_Manager<a class="headerlink" href="#ftc_manager" title="Permanent link">¶</a></h2> <p>Defined in FT_CACHE_H (freetype/ftcache.h).</p> <div class = "codehilite"><pre><code> <span class="keyword">typedef</span> <span class="keyword">struct</span> FTC_ManagerRec_* <b>FTC_Manager</b>; </code></pre></div> <p>This object corresponds to one instance of the cache-subsystem.

href="#synopsis" title="Permanent link">¶</a></h2> <p>While FreeType's CFF driver doesn't expose API functions by itself, it is possible to control its behaviour with <code><a href="ft2-module_management.html#ft_property_set">FT_Property_Set</a></code> and <code><a href="ft2-module_management.html#ft_property_get">FT_Property_Get</a></code>.</p> <p>The CFF driver's module name is ‘cff’.</p> <p>Available properties are <code><a href="ft2-properties.html#hinting-engine">hinting-engine</a></code>, <code><a href="ft2-properties.html#no-stem-darkening">no-stem-darkening</a></code>, <code><a href="ft2-properties.html#darkening-parameters">darkening-parameters</a></code>, and <code><a href="ft2-properties.html#random-seed">random-seed</a></code>, as documented in the ‘<a href="ft2-properties.html#properties">Driver properties</a>’ section.</p> <p><strong>Hinting and anti-aliasing principles of the new engine</strong></p> <p>The rasterizer is positioning horizontal features (e.g., ascender height & x-height, or crossbars) on the pixel grid and minimizing the amount of anti-aliasing applied to them, while placing vertical features (vertical stems) on the pixel grid without hinting, thus representing the stem position and weight accurately. Sometimes the vertical stems may be only partially black. In this context, ‘anti-aliasing’ means that stems are not positioned exactly on pixel borders, causing a fuzzy appearance.</p> <p>There are two principles behind this approach.</p> <p>1) No hinting in the horizontal direction: Unlike ‘superhinted’ TrueType, which changes glyph widths to accommodate regular inter-glyph spacing, Adobe's approach is ‘faithful to the design’ in representing both the glyph width and the inter-glyph spacing designed for the font. This makes the screen display as close as it can be to the result one would get with infinite resolution, while preserving what is considered the key characteristics of each glyph. Note that the distances between unhinted and grid-fitted positions at small sizes are comparable to kerning values and thus would be noticeable (and distracting) while reading if hinting were applied.</p> <p>One of the reasons to not hint horizontally is anti-aliasing for LCD screens: The pixel geometry of modern displays supplies three vertical subpixels as the eye moves horizontally across each visible pixel. On devices where we can be certain this characteristic is present a rasterizer can take advantage of the subpixels to add increments of weight. In Western writing systems this turns out to be the more critical direction anyway; the weights and spacing of vertical stems (see above) are central to Armenian, Cyrillic, Greek, and Latin type designs. Even when the rasterizer uses greyscale anti-aliasing instead of color (a necessary compromise when one doesn't know the screen characteristics), the unhinted vertical features preserve the design's weight and spacing much better than aliased type would.</p> <p>2) Alignment in the vertical direction: Weights and spacing along the y axis are less critical; what is much more important is the visual alignment of related features (like cap-height and x-height). The sense of alignment for these is enhanced by the sharpness of grid-fit edges, while the cruder vertical resolution (full pixels instead of ⅓ pixels) is less of a problem.</p> <p>On the technical side, horizontal alignment zones for ascender, x-height, and other important height values (traditionally called ‘blue zones’) as defined in the font are positioned independently, each being rounded to the nearest pixel edge, taking care of overshoot suppression at small sizes, stem darkening, and scaling.</p> <p>Hstems (this is, hint values defined in the font to help align horizontal features) that fall within a blue zone are said to be ‘captured’ and are aligned to that zone. Uncaptured stems are moved in one of four ways, top edge up or down, bottom edge up or down. Unless there are conflicting hstems, the smallest movement is taken to minimize distortion.</p> </article> </div> </div> </main> <footer class="md-footer"> <nav class="md-footer__inner md-grid" aria-label="Footer"> <a href="ft2-auto_hinter.html" class="md-footer__link md-footer__link--prev" aria-label="Previous: The auto-hinter" rel="prev"> <div class="md-footer__button md-icon"> <svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 24 24"><path d="M20 11v2H8l5.5 5.5-1.42 1.42L4.16 12l7.92-7.92L13.5 5.5 8 11h12z"/></svg> </div> <div class="md-footer__title"> <div class="md-ellipsis"> <span class="md-footer__direction"> Previous </span> The auto-hinter </div> </div> </a> <a href="ft2-t1_cid_driver.html" class="md-footer__link md-footer__link--next" aria-label="Next: The Type 1 and CID drivers" rel="next"> <div class="md-footer__title"> <div class="md-ellipsis"> <span class="md-footer__direction"> Next </span> The Type 1 and CID drivers </div> </div> <div class="md-footer__button md-icon"> <svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 24 24"><path d="M4 11v2h12l-5.5 5.5 1.42 1.42L19.84 12l-7.92-7.92L10.5 5.5 16 11H4z"/></svg> </div> </a> </nav> <div class="md-footer-meta md-typeset"> <div class="md-footer-meta__inner md-grid"> <div class="md-footer-copyright"> <div class="md-footer-copyright__highlight"> Copyright 2022 <a href = "https://www.freetype.org/license.html">The FreeType Project</a>. </div> Made with <a href="https://squidfunk.github.io/mkdocs-material/" target="_blank" rel="noopener"> Material for MkDocs </a> </div> </div> </div> </footer> </div> <div class="md-dialog" data-md-component="dialog"> <div class="md-dialog__inner md-typeset"></div> </div> <script id="__config" type="application/json">{"base": ".", "features": [], "translations": {"clipboard.copy": "Copy to clipboard", "clipboard.copied": "Copied to clipboard", "search.config.lang": "en", "search.config.pipeline": "trimmer, stopWordFilter", "search.config.separator": "[\\s\\-]+", "search.placeholder": "Search", "search.result.placeholder": "Type to start searching", "search.result.none": "No matching documents", "search.result.one": "1 matching document", "search.result.other": "# matching documents", "search.result.more.one": "1 more on this page", "search.result.more.other": "# more on this page", "search.result.term.missing": "Missing", "select.version.title": "Select version"}, "search": "assets/javascripts/workers/search.477d984a.min.js", "version": null}</script> <script src="assets/javascripts/bundle.82b56eb2.min.js"></script> <script src="javascripts/extra.js"></script> </body> </html>

<code>FT_Long</code> as arguments.

The first argument of the <code>FT_ERROR_DEF_</code> macro is the error label; by default, the prefix <code>FT_Err_</code> gets added so that you get error names like <code>FT_Err_Cannot_Open_Resource</code>. The second argument is the error code, and the last argument an error string, which is not used by FreeType.</p> <p>Within your application you should <strong>only</strong> use error names and <strong>never</strong> its numeric values! The latter might (and actually do) change in forthcoming FreeType versions.</p> <p>Macro <code>FT_NOERRORDEF_</code> defines <code>FT_Err_Ok</code>, which is always zero.

Codes</a> » Error Enumerations</p> <hr /> <h1 id="error-enumerations">Error Enumerations<a class="headerlink" href="#error-enumerations" title="Permanent link">¶</a></h1> <h2 id="synopsis">Synopsis<a class="headerlink" href="#synopsis" title="Permanent link">¶</a></h2> <p>The header file <code>fterrors.h</code> (which is automatically included by <code>freetype.h</code> defines the handling of FreeType's enumeration constants. It can also be used to generate error message strings with a small macro trick explained below.</p> <p><strong>Error Formats</strong></p> <p>The configuration macro <code>FT_CONFIG_OPTION_USE_MODULE_ERRORS</code> can be defined in <code>ftoption.h</code> in order to make the higher byte indicate the module where the error has happened (this is not compatible with standard builds of FreeType 2, however). See the file <code>ftmoderr.h</code> for more details.</p> <p><strong>Error Message Strings</strong></p> <p>Error definitions are set up with special macros that allow client applications to build a table of error message strings. The strings are not included in a normal build of FreeType 2 to save space (most client applications do not use them).</p> <p>To do so, you have to define the following macros before including this file. <div class="highlight"><pre><span></span><code> FT_ERROR_START_LIST </code></pre></div></p> <p>This macro is called before anything else to define the start of the error list. It is followed by several <code>FT_ERROR_DEF</code> calls. <div class="highlight"><pre><span></span><code> FT_ERROR_DEF( e, v, s ) </code></pre></div></p> <p>This macro is called to define one single error. ‘e’ is the error code identifier (e.g., <code>Invalid_Argument</code>), ‘v’ is the error's numerical value, and ‘s’ is the corresponding error string. <div class="highlight"><pre><span></span><code> FT_ERROR_END_LIST </code></pre></div></p> <p>This macro ends the list.</p> <p>Additionally, you have to undefine <code>FTERRORS_H_</code> before #including this file.</p> <p>Here is a simple example. <div class="highlight"><pre><span></span><code> #undef FTERRORS_H_ #define FT_ERRORDEF( e, v, s ) { e, s }, #define FT_ERROR_START_LIST { #define FT_ERROR_END_LIST { 0, NULL } }; const struct { int err_code; const char* err_msg; } ft_errors[] = #include <freetype/fterrors.h> </code></pre></div></p> <p>An alternative to using an array is a switch statement. <div class="highlight"><pre><span></span><code> #undef FTERRORS_H_ #define FT_ERROR_START_LIST switch ( error_code ) { #define FT_ERRORDEF( e, v, s ) case v: return s; #define FT_ERROR_END_LIST } </code></pre></div></p> <p>If you use <code>FT_CONFIG_OPTION_USE_MODULE_ERRORS</code>, <code>error_code</code> should be replaced with <code>FT_ERROR_BASE(error_code)</code> in the last example.</p> <h2 id="ft_error_string">FT_Error_String<a class="headerlink" href="#ft_error_string" title="Permanent link">¶</a></h2> <p>Defined in FT_ERRORS_H (freetype/fterrors.h).</p> <div class = "codehilite"><pre><code> FT_EXPORT( <span class="keyword">const</span> <span class="keyword">char</span>* ) <b>FT_Error_String</b>( <a href="ft2-basic_types.html#ft_error">FT_Error</a> error_code );

Variation Sequences<a class="headerlink" href="#unicode-variation-sequences" title="Permanent link">¶</a></h1> <h2 id="synopsis">Synopsis<a class="headerlink" href="#synopsis" title="Permanent link">¶</a></h2> <p>Many characters, especially for CJK scripts, have variant forms. They are a sort of grey area somewhere between being totally irrelevant and semantically distinct; for this reason, the Unicode consortium decided to introduce Variation Sequences (VS), consisting of a Unicode base character and a variation selector instead of further extending the already huge number of characters.</p> <p>Unicode maintains two different sets, namely ‘Standardized Variation Sequences’ and registered ‘Ideographic Variation Sequences’ (IVS), collected in the ‘Ideographic Variation Database’ (IVD).</p> <p><a href="https://unicode.org/Public/UCD/latest/ucd/StandardizedVariants.txt">https://unicode.org/Public/UCD/latest/ucd/StandardizedVariants.txt</a> <a href="https://unicode.org/reports/tr37/">https://unicode.org/reports/tr37/</a> <a href="https://unicode.org/ivd/">https://unicode.org/ivd/</a></p> <p>To date (January 2017), the character with the most ideographic variations is U+9089, having 32 such IVS.</p> <p>Three Mongolian Variation Selectors have the values U+180B-U+180D; 256 generic Variation Selectors are encoded in the ranges U+FE00-U+FE0F and U+E0100-U+E01EF. IVS currently use Variation Selectors from the range U+E0100-U+E01EF only.</p> <p>A VS consists of the base character value followed by a single Variation Selector. For example, to get the first variation of U+9089, you have to write the character sequence <code>U+9089 U+E0100</code>.</p> <p>Adobe and MS decided to support both standardized and ideographic VS with a new cmap subtable (format 14). It is an odd subtable because it is not a mapping of input code points to glyphs, but contains lists of all variations supported by the font.</p> <p>A variation may be either ‘default’ or ‘non-default’ for a given font. A default variation is the one you will get for that code point if you look it up in the standard Unicode cmap. A non-default variation is a different glyph.</p> <h2 id="ft_face_getcharvariantindex">FT_Face_GetCharVariantIndex<a class="headerlink" href="#ft_face_getcharvariantindex" title="Permanent link">¶</a></h2> <p>Defined in FT_FREETYPE_H (freetype/freetype.h).</p> <div class = "codehilite"><pre><code> FT_EXPORT( <a href="ft2-basic_types.html#ft_uint">FT_UInt</a> ) <b>FT_Face_GetCharVariantIndex</b>( <a href="ft2-base_interface.html#ft_face">FT_Face</a> face, <a href="ft2-basic_types.html#ft_ulong">FT_ULong</a> charcode, <a href="ft2-basic_types.html#ft_ulong">FT_ULong</a> variantSelector ); </code></pre></div> <p>Return the glyph index of a given character code as modified by the variation selector.</p> <h4>input</h4> <table class="fields"> <tr><td class="val" id="face">face</td><td class="desc"> <p>A handle to the source face object.</p> </td></tr> <tr><td class="val" id="charcode">charcode</td><td class="desc"> <p>The character code point in Unicode.</p> </td></tr> <tr><td class="val" id="variantselector">variantSelector</td><td class="desc"> <p>The Unicode code point of the variation selector.</p> </td></tr> </table> <h4>return</h4> <p>The glyph index. 0 means either ‘undefined character code’, or ‘undefined selector code’, or ‘no variation selector cmap subtable’, or ‘current CharMap is not Unicode’.</p> <h4>note</h4> <p>If you use FreeType to manipulate the contents of font files directly, be aware that the glyph index returned by this function doesn't always correspond to the internal indices used within the file.

section contains various functions used to perform so-called ‘incremental’ glyph loading. This is a mode where all glyphs loaded from a given <code><a href="ft2-base_interface.html#ft_face">FT_Face</a></code> are provided by the client application.</p> <p>Apart from that, all other tables are loaded normally from the font file.

Subpixel Rendering</p> <hr /> <h1 id="subpixel-rendering">Subpixel Rendering<a class="headerlink" href="#subpixel-rendering" title="Permanent link">¶</a></h1> <h2 id="synopsis">Synopsis<a class="headerlink" href="#synopsis" title="Permanent link">¶</a></h2> <p>FreeType provides two alternative subpixel rendering technologies. Should you define <code>FT_CONFIG_OPTION_SUBPIXEL_RENDERING</code> in your <code>ftoption.h</code> file, this enables ClearType-style rendering. Otherwise, Harmony LCD rendering is enabled. These technologies are controlled differently and API described below, although always available, performs its function when appropriate method is enabled and does nothing otherwise.</p> <p>ClearType-style LCD rendering exploits the color-striped structure of LCD pixels, increasing the available resolution in the direction of the stripe (usually horizontal RGB) by a factor of 3. Using the subpixel coverages unfiltered can create severe color fringes especially when rendering thin features. Indeed, to produce black-on-white text, the nearby color subpixels must be dimmed evenly. Therefore, an equalizing 5-tap FIR filter should be applied to subpixel coverages regardless of pixel boundaries and should have these properties:</p> <ol> <li> <p>It should be symmetrical, like { a, b, c, b, a }, to avoid any shifts in appearance.</p> </li> <li> <p>It should be color-balanced, meaning a + b = c, to reduce color fringes by distributing the computed coverage for one subpixel to all subpixels equally.</p> </li> <li> <p>It should be normalized, meaning 2a + 2b + c = 1.0 to maintain overall brightness.</p> </li> </ol> <p>Boxy 3-tap filter {0, ⅓, ⅓, ⅓, 0} is sharper but is less forgiving of non-ideal gamma curves of a screen (and viewing angles), beveled filters are fuzzier but more tolerant.</p> <p>Use the <code><a href="ft2-lcd_rendering.html#ft_library_setlcdfilter">FT_Library_SetLcdFilter</a></code> or <code><a href="ft2-lcd_rendering.html#ft_library_setlcdfilterweights">FT_Library_SetLcdFilterWeights</a></code> API to specify a low-pass filter, which is then applied to subpixel-rendered bitmaps generated through <code><a href="ft2-base_interface.html#ft_render_glyph">FT_Render_Glyph</a></code>.</p> <p>Harmony LCD rendering is suitable to panels with any regular subpixel structure, not just monitors with 3 color striped subpixels, as long as the color subpixels have fixed positions relative to the pixel center. In this case, each color channel can be rendered separately after shifting the outline opposite to the subpixel shift so that the coverage maps are aligned. This method is immune to color fringes because the shifts do not change integral coverage.</p> <p>The subpixel geometry must be specified by xy-coordinates for each subpixel. By convention they may come in the RGB order: {{-⅓, 0}, {0, 0}, {⅓, 0}} for standard RGB striped panel or {{-⅙, ¼}, {-⅙, -¼}, {⅓, 0}} for a certain PenTile panel.</p> <p>Use the <code><a href="ft2-lcd_rendering.html#ft_library_setlcdgeometry">FT_Library_SetLcdGeometry</a></code> API to specify subpixel positions. If one follows the RGB order convention, the same order applies to the resulting <code><a href="ft2-basic_types.html#ft_pixel_mode">FT_PIXEL_MODE_LCD</a></code> and <code><a href="ft2-basic_types.html#ft_pixel_mode">FT_PIXEL_MODE_LCD_V</a></code> bitmaps. Note, however, that the coordinate frame for the latter must be rotated clockwise. Harmony with default LCD geometry is equivalent to ClearType with light filter.</p> <p>As a result of ClearType filtering or Harmony shifts, the resulting dimensions of LCD bitmaps can be slightly wider or taller than the dimensions the original outline with regard to the pixel grid. For example, for <code><a href="ft2-base_interface.html#ft_render_mode">FT_RENDER_MODE_LCD</a></code>, the filter adds 2 subpixels to the left, and 2 subpixels to the right. The bitmap offset values are adjusted accordingly, so clients shouldn't need to modify their layout and glyph positioning code when enabling the filter.</p> <p>The ClearType and Harmony rendering is applicable to glyph bitmaps rendered through <code><a href="ft2-base_interface.html#ft_render_glyph">FT_Render_Glyph</a></code>, <code><a href="ft2-base_interface.html#ft_load_glyph">FT_Load_Glyph</a></code>, <code><a href="ft2-base_interface.html#ft_load_char">FT_Load_Char</a></code>, and <code><a href="ft2-glyph_management.html#ft_glyph_to_bitmap">FT_Glyph_To_Bitmap</a></code>, when <code><a href="ft2-base_interface.html#ft_render_mode">FT_RENDER_MODE_LCD</a></code> or <code><a href="ft2-base_interface.html#ft_render_mode">FT_RENDER_MODE_LCD_V</a></code> is specified. This API does not control <code><a href="ft2-outline_processing.html#ft_outline_render">FT_Outline_Render</a></code> and <code><a href="ft2-outline_processing.html#ft_outline_get_bitmap">FT_Outline_Get_Bitmap</a></code>.</p> <p>The described algorithms can completely remove color artefacts when combined with gamma-corrected alpha blending in linear space. Each of the 3 alpha values (subpixels) must by independently used to blend one color channel. That is, red alpha blends the red channel of the text color with the red channel of the background pixel.</p> <h2 id="ft_lcdfilter">FT_LcdFilter<a class="headerlink" href="#ft_lcdfilter" title="Permanent link">¶</a></h2> <p>Defined in FT_LCD_FILTER_H (freetype/ftlcdfil.h).</p> <div class = "codehilite"><pre><code> <span class="keyword">typedef</span> <span class="keyword">enum</span> FT_LcdFilter_ { <a href="ft2-lcd_rendering.html#ft_lcd_filter_none">FT_LCD_FILTER_NONE</a> = 0, <a href="ft2-lcd_rendering.html#ft_lcd_filter_default">FT_LCD_FILTER_DEFAULT</a> = 1, <a href="ft2-lcd_rendering.html#ft_lcd_filter_light">FT_LCD_FILTER_LIGHT</a> = 2, <a href="ft2-lcd_rendering.html#ft_lcd_filter_legacy1">FT_LCD_FILTER_LEGACY1</a> = 3, <a href="ft2-lcd_rendering.html#ft_lcd_filter_legacy">FT_LCD_FILTER_LEGACY</a> = 16, FT_LCD_FILTER_MAX /* do not remove */ } <b>FT_LcdFilter</b>; </code></pre></div> <p>A list of values to identify various types of LCD filters.</p> <h4>values</h4> <table class="fields"> <tr><td class="val" id="ft_lcd_filter_none">FT_LCD_FILTER_NONE</td><td class="desc"> <p>Do not perform filtering.

This means that if no font driver is capable of handling the raw compressed file, the library will try to open a LZW stream from it and re-open the face with it.</p> <p>The stream implementation is very basic and resets the decompression process each time seeking backwards is needed within the stream, which significantly undermines the performance.</p> <p>This section contains the declaration of LZW-specific functions.</p> <h2 id="ft_stream_openlzw">FT_Stream_OpenLZW<a class="headerlink" href="#ft_stream_openlzw" title="Permanent link">¶</a></h2> <p>Defined in FT_LZW_H (freetype/ftlzw.h).</p> <div class = "codehilite"><pre><code> FT_EXPORT( <a href="ft2-basic_types.html#ft_error">FT_Error</a> ) <b>FT_Stream_OpenLZW</b>( <a href="ft2-system_interface.html#ft_stream">FT_Stream</a> stream, <a href="ft2-system_interface.html#ft_stream">FT_Stream</a> source ); </code></pre></div> <p>Open a new stream to parse LZW-compressed font files.

<p>FreeType is a library that provides access to glyphs in font files. It scales the glyph images and their metrics to a requested size, and it rasterizes the glyph images to produce pixel or subpixel alpha coverage bitmaps.</p> <p>Note that FreeType is <em>not</em> a text layout engine. You have to use higher-level libraries like HarfBuzz, Pango, or ICU for that.</p> <p>Note also that FreeType does <em>not</em> perform alpha blending or compositing the resulting bitmaps or pixmaps by itself. Use your favourite graphics library (for example, Cairo or Skia) to further process FreeType's output.</p> </article> </div> </div> </main> <footer class="md-footer"> <nav class="md-footer__inner md-grid" aria-label="Footer"> <a href="ft2-index.html" class="md-footer__link md-footer__link--prev" aria-label="Previous: Index" rel="prev"> <div class="md-footer__button md-icon"> <svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 24 24"><path d="M20 11v2H8l5.5 5.5-1.42 1.42L4.16 12l7.92-7.92L13.5 5.5 8 11h12z"/></svg> </div> <div class="md-footer__title"> <div class="md-ellipsis"> <span class="md-footer__direction"> Previous </span> Index </div> </div> </a> <a href="ft2-header_inclusion.html" class="md-footer__link md-footer__link--next" aria-label="Next: FreeType's header inclusion scheme" rel="next"> <div class="md-footer__title"> <div class="md-ellipsis"> <span class="md-footer__direction"> Next </span> FreeType's header inclusion scheme </div> </div> <div class="md-footer__button md-icon"> <svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 24 24"><path d="M4 11v2h12l-5.5 5.5 1.42 1.42L19.84 12l-7.92-7.92L10.5 5.5 16 11H4z"/></svg> </div> </a> </nav> <div class="md-footer-meta md-typeset"> <div class="md-footer-meta__inner md-grid"> <div class="md-footer-copyright"> <div class="md-footer-copyright__highlight"> Copyright 2022 <a href = "https://www.freetype.org/license.html">The FreeType Project</a>. </div> Made with <a href="https://squidfunk.github.io/mkdocs-material/" target="_blank" rel="noopener"> Material for MkDocs </a> </div> </div> </div> </footer> </div> <div class="md-dialog" data-md-component="dialog"> <div class="md-dialog__inner md-typeset"></div> </div> <script id="__config" type="application/json">{"base": ".", "features": [], "translations": {"clipboard.copy": "Copy to clipboard", "clipboard.copied": "Copied to clipboard", "search.config.lang": "en", "search.config.pipeline": "trimmer, stopWordFilter", "search.config.separator": "[\\s\\-]+", "search.placeholder": "Search", "search.result.placeholder": "Type to start searching", "search.result.none": "No matching documents", "search.result.one": "1 matching document", "search.result.other": "# matching documents", "search.result.more.one": "1 more on this page", "search.result.more.other": "# more on this page", "search.result.term.missing": "Missing", "select.version.title": "Select version"}, "search": "assets/javascripts/workers/search.477d984a.min.js", "version": null}</script> <script src="assets/javascripts/bundle.82b56eb2.min.js"></script> <script src="javascripts/extra.js"></script> </body> </html>

If this configuration macro isn't defined, ‘hinting-engine’ does nothing.</p> <p>The same holds for the Type 1 and CID modules if compiled with <code>T1_CONFIG_OPTION_OLD_ENGINE</code>.</p> <p>For the ‘cff’ module, the default engine is ‘adobe’. For both the ‘type1’ and ‘t1cid’ modules, the default engine is ‘adobe’, too.</p> <h4>note</h4> <p>This property can be used with <code><a href="ft2-module_management.html#ft_property_get">FT_Property_Get</a></code> also.</p> <p>This property can be set via the <code>FREETYPE_PROPERTIES</code> environment variable (using values ‘adobe’ or ‘freetype’).</p> <h4>example</h4> <p>The following example code demonstrates how to select Adobe's hinting engine for the ‘cff’ module (omitting the error handling). <div class="highlight"><pre><span></span><code> FT_Library library; FT_UInt hinting_engine = FT_HINTING_ADOBE; FT_Init_FreeType( &library ); FT_Property_Set( library, "cff", "hinting-engine", &hinting_engine ); </code></pre></div></p> <h4>since</h4> <p>2.4.12 (for ‘cff’ module)</p> <p>2.9 (for ‘type1’ and ‘t1cid’ modules)</p> <hr> <h2 id="no-stem-darkening">no-stem-darkening<a class="headerlink" href="#no-stem-darkening" title="Permanent link">¶</a></h2> <p>All glyphs that pass through the auto-hinter will be emboldened unless this property is set to TRUE. The same is true for the CFF, Type 1, and CID font modules if the ‘Adobe’ engine is selected (which is the default).</p> <p>Stem darkening emboldens glyphs at smaller sizes to make them more readable on common low-DPI screens when using linear alpha blending and gamma correction, see <code><a href="ft2-base_interface.html#ft_render_glyph">FT_Render_Glyph</a></code>. When not using linear alpha blending and gamma correction, glyphs will appear heavy and fuzzy!</p> <p>Gamma correction essentially lightens fonts since shades of grey are shifted to higher pixel values (= higher brightness) to match the original intention to the reality of our screens. The side-effect is that glyphs ‘thin out’. Mac OS X and Adobe's proprietary font rendering library implement a counter-measure: stem darkening at smaller sizes where shades of gray dominate. By emboldening a glyph slightly in relation to its pixel size, individual pixels get higher coverage of filled-in outlines and are therefore ‘blacker’. This counteracts the ‘thinning out’ of glyphs, making text remain readable at smaller sizes.</p> <p>For the auto-hinter, stem-darkening is experimental currently and thus switched off by default (this is, <code>no-stem-darkening</code> is set to TRUE by default). Total consistency with the CFF driver is not achieved right now because the emboldening method differs and glyphs must be scaled down on the Y-axis to keep outline points inside their precomputed blue zones. The smaller the size (especially 9ppem and down), the higher the loss of emboldening versus the CFF driver.</p> <p>Note that stem darkening is never applied if <code><a href="ft2-base_interface.html#ft_load_xxx">FT_LOAD_NO_SCALE</a></code> is set.</p> <h4>note</h4> <p>This property can be used with <code><a href="ft2-module_management.html#ft_property_get">FT_Property_Get</a></code> also.</p> <p>This property can be set via the <code>FREETYPE_PROPERTIES</code> environment variable (using values 1 and 0 for ‘on’ and ‘off’, respectively).

At configuration time, these four control points can be set with the macro <code>CFF_CONFIG_OPTION_DARKENING_PARAMETERS</code>; the CFF, Type 1, and CID drivers share these values. At runtime, the control points can be changed using the <code>darkening-parameters</code> property (see the example below that demonstrates this for the Type 1 driver).</p> <p>The x values give the stem width, and the y values the darkening amount. The unit is 1000<sup>th</sup> of pixels. All coordinate values must be positive; the x values must be monotonically increasing; the y values must be monotonically decreasing and smaller than or equal to 500 (corresponding to half a pixel); the slope of each linear piece must be shallower than -1 (e.g., -.4).</p> <p>The auto-hinter provides this property, too, as an experimental feature.

However, mainly for debugging purposes, it is often necessary to use a known value as a seed so that the pseudo-random number sequences generated by ‘random’ are repeatable.</p> <p>The <code>random-seed</code> property does that. Its argument is a signed 32bit integer; if the value is zero or negative, the seed given by the <code>intitialRandomSeed</code> private DICT operator in a CFF file gets used (or a default value if there is no such operator). If the value is positive, use it instead of <code>initialRandomSeed</code>, which is consequently ignored.</p> <h4>note</h4> <p>This property can be set via the <code>FREETYPE_PROPERTIES</code> environment variable.

When selecting ‘Fixed’ in KDE or Gnome one gets results that appear rather random, the style changes often if one changes the size and one cannot select some fonts at all. The improve this situation, the PCF module prepends the foundry name (plus a space) to the family name.

As a consequence, the version numbers returned by a call to the ‘GETINFO’ bytecode instruction are more convoluted than desired.</p> <p>Here are two tables that try to shed some light on the possible values for the MS rasterizer engine, together with the additional features introduced by it. <div class="highlight"><pre><span></span><code> GETINFO framework version feature ------------------------------------------------------------------- 3 GDI (Win 3.1), v1.0 16-bit, first version TrueImage 33 GDI (Win NT 3.1), v1.5 32-bit HP Laserjet 34 GDI (Win 95) v1.6 font smoothing, new SCANTYPE opcode 35 GDI (Win 98/2000) v1.7 (UN)SCALED_COMPONENT_OFFSET bits in composite glyphs 36 MGDI (Win CE 2) v1.6+ classic ClearType 37 GDI (XP and later), v1.8 ClearType GDI+ old (before Vista) 38 GDI+ old (Vista, Win 7), v1.9 subpixel ClearType, WPF Y-direction ClearType, additional error checking 39 DWrite (before Win 8) v2.0 subpixel ClearType flags in GETINFO opcode, bug fixes 40 GDI+ (after Win 7), v2.1 Y-direction ClearType flag DWrite (Win 8) in GETINFO opcode, Gray ClearType </code></pre></div></p> <p>The ‘version’ field gives a rough orientation only, since some applications provided certain features much earlier (as an example, Microsoft Reader used subpixel and Y-direction ClearType already in Windows 2000). Similarly, updates to a given framework might include improved hinting support. <div class="highlight"><pre><span></span><code> version sampling rendering comment x y x y -------------------------------------------------------------- v1.0 normal normal B/W B/W bi-level v1.6 high high gray gray grayscale v1.8 high normal color-filter B/W (GDI) ClearType v1.9 high high color-filter gray Color ClearType v2.1 high normal gray B/W Gray ClearType v2.1 high high gray gray Gray ClearType </code></pre></div></p> <p>Color and Gray ClearType are the two available variants of ‘Y-direction ClearType’, meaning grayscale rasterization along the Y-direction; the name used in the TrueType specification for this feature is ‘symmetric smoothing’. ‘Classic ClearType’ is the original algorithm used before introducing a modified version in Win XP. Another name for v1.6's grayscale rendering is ‘font smoothing’, and ‘Color ClearType’ is sometimes also called ‘DWrite ClearType’. To differentiate between today's Color ClearType and the earlier ClearType variant with B/W rendering along the vertical axis, the latter is sometimes called ‘GDI ClearType’.</p> <p>‘Normal’ and ‘high’ sampling describe the (virtual) resolution to access the rasterized outline after the hinting process. ‘Normal’ means 1 sample per grid line (i.e., B/W). In the current Microsoft implementation, ‘high’ means an extra virtual resolution of 16x16 (or 16x1) grid lines per pixel for bytecode instructions like ‘MIRP’. After hinting, these 16 grid lines are mapped to 6x5 (or 6x1) grid lines for color filtering if Color ClearType is activated.</p> <p>Note that ‘Gray ClearType’ is essentially the same as v1.6's grayscale rendering. However, the GETINFO instruction handles it differently: v1.6 returns bit 12 (hinting for grayscale), while v2.1 returns bits 13 (hinting for ClearType), 18 (symmetrical smoothing), and 19 (Gray ClearType). Also, this mode respects bits 2 and 3 for the version 1 gasp table exclusively (like Color ClearType), while v1.6 only respects the values of version 0 (bits 0 and 1).</p> <p>Keep in mind that the features of the above interpreter versions might not map exactly to FreeType features or behavior because it is a fundamentally different library with different internals.</p> <hr> <h2 id="interpreter-version">interpreter-version<a class="headerlink" href="#interpreter-version" title="Permanent link">¶</a></h2> <p>Currently, three versions are available, two representing the bytecode interpreter with subpixel hinting support (old ‘Infinality’ code and new stripped-down and higher performance ‘minimal’ code) and one without, respectively. The default is subpixel support if <code>TT_CONFIG_OPTION_SUBPIXEL_HINTING</code> is defined, and no subpixel support otherwise (since it isn't available then).</p> <p>If subpixel hinting is on, many TrueType bytecode instructions behave differently compared to B/W or grayscale rendering (except if ‘native ClearType’ is selected by the font). Microsoft's main idea is to render at a much increased horizontal resolution, then sampling down the created output to subpixel precision. However, many older fonts are not suited to this and must be specially taken care of by applying (hardcoded) tweaks in Microsoft's interpreter.</p> <p>Details on subpixel hinting and some of the necessary tweaks can be found in Greg Hitchcock's whitepaper at ‘<a href="https://www.microsoft.com/typography/cleartype/truetypecleartype.aspx">https://www.microsoft.com/typography/cleartype/truetypecleartype.aspx</a>’. Note that FreeType currently doesn't really ‘subpixel hint’ (6x1, 6x2, or 6x5 supersampling) like discussed in the paper. Depending on the chosen interpreter, it simply ignores instructions on vertical stems to arrive at very similar results.</p> <h4>note</h4> <p>This property can be used with <code><a href="ft2-module_management.html#ft_property_get">FT_Property_Get</a></code> also.</p> <p>This property can be set via the <code>FREETYPE_PROPERTIES</code> environment variable (using values ‘35’, ‘38’, or ‘40’).</p> <h4>example</h4> <p>The following example code demonstrates how to deactivate subpixel hinting (omitting the error handling). <div class="highlight"><pre><span></span><code> FT_Library library; FT_Face face; FT_UInt interpreter_version = TT_INTERPRETER_VERSION_35; FT_Init_FreeType( &library ); FT_Property_Set( library, "truetype", "interpreter-version", &interpreter_version ); </code></pre></div></p> <h4>since</h4> <p>2.5</p> <hr> <h2 id="svg-hooks">svg-hooks<a class="headerlink" href="#svg-hooks" title="Permanent link">¶</a></h2> <p>Set up the interface between FreeType and an extern SVG rendering library like ‘librsvg’.

Examples of supported scripts are Latin or CJK. Before a glyph is auto-hinted, the Unicode character map of the font gets examined, and the script is then determined based on Unicode character ranges, see below.</p> <p>OpenType fonts, however, often provide much more glyphs than character codes (small caps, superscripts, ligatures, swashes, etc.), to be controlled by so-called ‘features’. Handling OpenType features can be quite complicated and thus needs a separate library on top of FreeType.</p> <p>The mapping between glyph indices and scripts (in the auto-hinter sense, see the <code><a href="ft2-properties.html#ft_autohinter_script_xxx">FT_AUTOHINTER_SCRIPT_XXX</a></code> values) is stored as an array with <code>num_glyphs</code> elements, as found in the font's <code><a href="ft2-base_interface.html#ft_face">FT_Face</a></code> structure.

title="Permanent link">¶</a></h2> <p>A raster or a rasterizer is a scan converter in charge of producing a pixel coverage bitmap that can be used as an alpha channel when compositing a glyph with a background. FreeType comes with two rasterizers: bilevel <code>raster1</code> and anti-aliased <code>smooth</code> are two separate modules. They are usually called from the high-level <code><a href="ft2-base_interface.html#ft_load_glyph">FT_Load_Glyph</a></code> or <code><a href="ft2-base_interface.html#ft_render_glyph">FT_Render_Glyph</a></code> functions and produce the entire coverage bitmap at once, while staying largely invisible to users.</p> <p>Instead of working with complete coverage bitmaps, it is also possible to intercept consecutive pixel runs on the same scanline with the same coverage, called <em>spans</em>, and process them individually. Only the <code>smooth</code> rasterizer permits this when calling <code><a href="ft2-outline_processing.html#ft_outline_render">FT_Outline_Render</a></code> with <code><a href="ft2-raster.html#ft_raster_params">FT_Raster_Params</a></code> as described below.</p> <p>Working with either complete bitmaps or spans it is important to think of them as colorless coverage objects suitable as alpha channels to blend arbitrary colors with a background. For best results, it is recommended to use gamma correction, too.</p> <p>This section also describes the public API needed to set up alternative <code><a href="ft2-module_management.html#ft_renderer">FT_Renderer</a></code> modules.</p> <h2 id="ft_span">FT_Span<a class="headerlink" href="#ft_span" title="Permanent link">¶</a></h2> <p>Defined in FT_IMAGE_H (freetype/ftimage.h).</p> <div class = "codehilite"><pre><code> <span class="keyword">typedef</span> <span class="keyword">struct</span> FT_Span_ { <span class="keyword">short</span> x; <span class="keyword">unsigned</span> <span class="keyword">short</span> len; <span class="keyword">unsigned</span> <span class="keyword">char</span> coverage; } <b>FT_Span</b>; </code></pre></div> <p>A structure to model a single span of consecutive pixels when rendering an anti-aliased bitmap.</p> <h4>fields</h4> <table class="fields"> <tr><td class="val" id="x">x</td><td class="desc"> <p>The span's horizontal start position.</p> </td></tr> <tr><td class="val" id="len">len</td><td class="desc"> <p>The span's length in pixels.</p> </td></tr> <tr><td class="val" id="coverage">coverage</td><td class="desc"> <p>The span color/coverage, ranging from 0 (background) to 255 (foreground).</p> </td></tr> </table> <h4>note</h4> <p>This structure is used by the span drawing callback type named <code><a href="ft2-raster.html#ft_spanfunc">FT_SpanFunc</a></code> that takes the y coordinate of the span as a parameter.</p> <p>The anti-aliased rasterizer produces coverage values from 0 to 255, this is, from completely transparent to completely opaque.</p> <hr> <h2 id="ft_spanfunc">FT_SpanFunc<a class="headerlink" href="#ft_spanfunc" title="Permanent link">¶</a></h2> <p>Defined in FT_IMAGE_H (freetype/ftimage.h).</p> <div class = "codehilite"><pre><code> <span class="keyword">typedef</span> <span class="keyword">void</span> (*<b>FT_SpanFunc</b>)( <span class="keyword">int</span> y, <span class="keyword">int</span> count, <span class="keyword">const</span> <a href="ft2-raster.html#ft_span">FT_Span</a>* spans, <span class="keyword">void</span>* user ); #<span class="keyword">define</span> FT_Raster_Span_Func <b>FT_SpanFunc</b> </code></pre></div> <p>A function used as a call-back by the anti-aliased renderer in order to let client applications draw themselves the pixel spans on each scan line.</p> <h4>input</h4> <table class="fields"> <tr><td class="val" id="y">y</td><td class="desc"> <p>The scanline's upward y coordinate.</p> </td></tr> <tr><td class="val" id="count">count</td><td class="desc"> <p>The number of spans to draw on this scanline.</p> </td></tr> <tr><td class="val" id="spans">spans</td><td class="desc"> <p>A table of <code>count</code> spans to draw on the scanline.</p> </td></tr> <tr><td class="val" id="user">user</td><td class="desc"> <p>User-supplied data that is passed to the callback.</p> </td></tr> </table> <h4>note</h4> <p>This callback allows client applications to directly render the spans of the anti-aliased bitmap to any kind of surfaces.</p> <p>This can be used to write anti-aliased outlines directly to a given background bitmap using alpha compositing.
