+ BLP1 files, used mostly in Warcraft III, are not fully supported.
10
+ All types of BLP2 files used in World of Warcraft are supported.
11
+
12
+ The BLP file structure consists of a header, up to 16 mipmaps of the
13
+ texture
14
+
15
+ Texture sizes must be powers of two, though the two dimensions do
16
+ not have to be equal; 512x256 is valid, but 512x200 is not.
17
+ The first mipmap (mipmap #0) is the full size image; each subsequent
18
+ mipmap halves both dimensions. The final mipmap should be 1x1.
19
+
20
+ BLP files come in many different flavours:
21
+ * JPEG-compressed (type == 0) - only supported for BLP1.
22
+ * RAW images (type == 1, encoding == 1). Each mipmap is stored as an
23
+ array of 8-bit values, one per pixel, left to right, top to bottom.
24
+ Each value is an index to the palette.
25
+ * DXT-compressed (type == 1, encoding == 2):
26
+ - DXT1 compression is used if alpha_encoding == 0.
27
+ - An additional alpha bit is used if alpha_depth == 1.
28
+ - DXT3 compression is used if alpha_encoding == 1.
29
+ - DXT5 compression is used if alpha_encoding == 7.

+ Independence War 2: Edge Of Chaos - Texture File Format - 16 October 2001
10
+
11
+ The textures used for 3D objects in Independence War 2: Edge Of Chaos are in a
12
+ packed custom format called FTEX. This file format uses file extensions FTC
13
+ and FTU.
14
+ * FTC files are compressed textures (using standard texture compression).
15
+ * FTU files are not compressed.
16
+ Texture File Format
17
+ The FTC and FTU texture files both use the same format. This
18
+ has the following structure:
19
+ {header}
20
+ {format_directory}
21
+ {data}
22
+ Where:
23
+ {header} = {
24
+ u32:magic,
25
+ u32:version,
26
+ u32:width,
27
+ u32:height,
28
+ u32:mipmap_count,
29
+ u32:format_count
30
+ }
31
+
32
+ * The "magic" number is "FTEX".
33
+ * "width" and "height" are the dimensions of the texture.
34
+ * "mipmap_count" is the number of mipmaps in the texture.
35
+ * "format_count" is the number of texture formats (different versions of the
36
+ same texture) in this file.
37
+
38
+ {format_directory} = format_count * { u32:format, u32:where }
39
+
40
+ The format value is 0 for DXT1 compressed textures and 1 for 24-bit RGB
41
+ uncompressed textures.
42
+ The texture data for a format starts at the position "where" in the file.
43
+
44
+ Each set of texture data in the file has the following structure:
45
+ {data} = format_count * { u32:mipmap_size, mipmap_size * { u8 } }
46
+ * "mipmap_size" is the number of bytes in that mip level. For compressed
47
+ textures this is the size of the texture data compressed with DXT1. For 24 bit
48
+ uncompressed textures, this is 3 * width * height. Following this are the image
49
+ bytes for that mipmap level.
50
+
51
+ Note: All data is stored in little-Endian (Intel) byte order.

57
+ Originally released under LGPL. Graciously donated to PIL in
58
+ March 2009, for distribution under the standard PIL license
59
+
60
+ The pyCMS.py module provides a "clean" interface between Python/PIL and
61
+ pyCMSdll, taking care of some of the more complex handling of the direct
62
+ pyCMSdll functions, as well as error-checking and making sure that all
63
+ relevant data is kept together.
64
+
65
+ While it is possible to call pyCMSdll functions directly, it's not highly
66
+ recommended.
67
+
68
+ Version History:
69
+
70
+ 1.0.0 pil Oct 2013 Port to LCMS 2.
71
+
72
+ 0.1.0 pil mod March 10, 2009
73
+
74
+ Renamed display profile to proof profile. The proof
75
+ profile is the profile of the device that is being
76
+ simulated, not the profile of the device which is
77
+ actually used to display/print the final simulation
78
+ (that'd be the output profile) - also see LCMSAPI.txt
79
+ input colorspace -> using 'renderingIntent' -> proof
80
+ colorspace -> using 'proofRenderingIntent' -> output
81
+ colorspace
82
+
83
+ Added LCMS FLAGS support.
84
+ Added FLAGS["SOFTPROOFING"] as default flag for
85
+ buildProofTransform (otherwise the proof profile/intent
86
+ would be ignored).
87
+
88
+ 0.1.0 pil March 2009 - added to PIL, as PIL.ImageCms
89
+
90
+ 0.0.2 alpha Jan 6, 2002
91
+
92
+ Added try/except statements around type() checks of
93
+ potential CObjects... Python won't let you use type()
94
+ on them, and raises a TypeError (stupid, if you ask
95
+ me!)
96
+
97
+ Added buildProofTransformFromOpenProfiles() function.
98
+ Additional fixes in DLL, see DLL code for details.
99

7
+ # History:
8
+ # 1996-08-07 fl created (experimental)
9
+ # 1997-08-25 fl minor adjustments to handle fonts from pilfont 0.3
10
+ # 1999-02-06 fl rewrote most font management stuff in C
11
+ # 1999-03-17 fl take pth files into account in load_path (from Richard Jones)
12
+ # 2001-02-17 fl added freetype support
13
+ # 2001-05-09 fl added TransposedFont wrapper class
14
+ # 2002-03-04 fl make sure we have a "L" or "1" font
15
+ # 2002-12-04 fl skip non-directory entries in the system path
16
+ # 2003-04-29 fl add embedded default font
17
+ # 2003-09-27 fl added support for truetype charmap encodings
18
+ #
19
+ # Todo:
20
+ # Adapt to PILFONT2 format (16-bit fonts, compressed, single file)

+ Load a TrueType or OpenType font from a file or file-like object,

796

798
+ Pillow uses FreeType to open font files. On Windows, be aware that FreeType
799
+ will keep the file open as long as the FreeTypeFont object exists. Windows
800
+ limits the number of files that can be open in C at once to 512, so if many
801
+ fonts are opened simultaneously and that limit is approached, an
802
+ ``OSError`` may be thrown, reporting that FreeType "cannot open resource".
803
+ A workaround would be to copy the file(s) into memory, and open that instead.

811
+ * The :file:`fonts/` directory on Windows,
812
+ * :file:`/Library/Fonts/`, :file:`/System/Library/Fonts/`
813

814
+ * :file:`~/.local/share/fonts`, :file:`/usr/local/share/fonts`,
815
+ and :file:`/usr/share/fonts` on Linux; or those specified by
816
+ the ``XDG_DATA_HOME`` and ``XDG_DATA_DIRS`` environment variables
817
+ for user-installed and system-wide fonts, respectively.
818
+
819
+ :param size: The requested size, in pixels.
820
+ :param index: Which font face to load (default is first available face).
821
+ :param encoding: Which font encoding to use (default is Unicode). Possible
822
+ encodings include (see the FreeType documentation for more
823
+ information):
824
+
825
+ * "unic" (Unicode)
826

827

843
+ Otherwise, basic layout will be used.
844

845
+ Raqm layout is recommended for all non-English text. If Raqm layout
846

37
