% November 26, 2002 -- glennrp -- see also "To do" under WriteMNGImage):
%
% Get 16-bit cheap transparency working.
%
% (At this point, PNG decoding is supposed to be in full MNG-LC compliance)
%
% Preserve all unknown and not-yet-handled known chunks found in input
% PNG file and copy them into output PNG files according to the PNG
% copying rules.
%
% (At this point, PNG encoding should be in full MNG compliance)
%
% Provide options for choice of background to use when the MNG BACK
% chunk is not present or is not mandatory (i.e., leave transparent,
% user specified, MNG BACK, PNG bKGD)
%
% Implement LOOP/ENDL [done, but could do discretionary loops more
% efficiently by linking in the duplicate frames.].
%
% Decode and act on the MHDR simplicity profile (offer option to reject
% files or attempt to process them anyway when the profile isn't LC or VLC).
%
% Upgrade to full MNG without Delta-PNG.
%
% o BACK [done a while ago except for background image ID]
% o MOVE [done 15 May 1999]
% o CLIP [done 15 May 1999]
% o DISC [done 19 May 1999]
% o SAVE [partially done 19 May 1999 (marks objects frozen)]
% o SEEK [partially done 19 May 1999 (discard function only)]
% o SHOW
% o PAST
% o BASI
% o MNG-level tEXt/iTXt/zTXt
% o pHYg
% o pHYs
% o sBIT
% o bKGD
% o iTXt (wait for libpng implementation).
%
% Use the scene signature to discover when an identical scene is
% being reused, and just point to the original image->exception instead
% of storing another set of pixels. This not specific to MNG
% but could be applied generally.
%
% Upgrade to full MNG with Delta-PNG.
%

%

% They are really Xcode files meant for display on the iPhone.
% These are not valid PNG files and it is impossible to recover

% WriteMNGImage() writes an image in the Portable Network Graphics
% Group's "Multiple-image Network Graphics" encoded image format.
%
% MNG support written by Glenn Randers-Pehrson, glennrp@image...
%
% The format of the WriteMNGImage method is:
%
% MagickBooleanType WriteMNGImage(const ImageInfo *image_info,Image *image)
%
% A description of each parameter follows.
%
% o image_info: the image info.
%
% o image: The image.
%
%
% To do (as of version 5.5.2, November 26, 2002 -- glennrp -- see also
% "To do" under ReadPNGImage):
%
% Preserve all unknown and not-yet-handled known chunks found in input
% PNG file and copy them into output PNG files according to the PNG
% copying rules.
%
% Write the iCCP chunk at MNG level when (icc profile length > 0)
%
% Improve selection of color type (use indexed-colour or indexed-colour
% with tRNS when 256 or fewer unique RGBA values are present).
%
% Figure out what to do with "dispose=<restore-to-previous>" (dispose == 3)
% This will be complicated if we limit ourselves to generating MNG-LC
% files. For now we ignore disposal method 3 and simply overlay the next
% image on it.
%
% Check for identical PLTE's or PLTE/tRNS combinations and use a
% global MNG PLTE or PLTE/tRNS combination when appropriate.
% [mostly done 15 June 1999 but still need to take care of tRNS]
%
% Check for identical sRGB and replace with a global sRGB (and remove
% gAMA/cHRM if sRGB is found; check for identical gAMA/cHRM and
% replace with global gAMA/cHRM (or with sRGB if appropriate; replace
% local gAMA/cHRM with local sRGB if appropriate).
%
% Check for identical sBIT chunks and write global ones.
%
% Provide option to skip writing the signature tEXt chunks.
%
% Use signatures to detect identical objects and reuse the first
% instance of such objects instead of writing duplicate objects.
%
% Use a smaller-than-32k value of compression window size when
% appropriate.
%
% Encode JNG datastreams. Mostly done as of 5.5.2; need to write
% ancillary text chunks and save profiles.
%
% Provide an option to force LC files (to ensure exact framing rate)
% instead of VLC.
%
% Provide an option to force VLC files instead of LC, even when offsets
% are present. This will involve expanding the embedded images with a
% transparent region at the top and/or left.

%
% WritePNGImage() writes a Portable Network Graphics (PNG) or
% Multiple-image Network Graphics (MNG) image file.
%
% MNG support written by Glenn Randers-Pehrson, glennrp@image...
%
% The format of the WritePNGImage method is:
%
% MagickBooleanType WritePNGImage(const ImageInfo *image_info,Image *image)
%
% A description of each parameter follows:
%
% o image_info: the image info.
%
% o image: The image.
%
% Returns MagickTrue on success, MagickFalse on failure.
%
% Communicating with the PNG encoder:
%
% While the datastream written is always in PNG format and normally would
% be given the "png" file extension, this method also writes the following
% pseudo-formats which are subsets of png:
%
% o PNG8: An 8-bit indexed PNG datastream is written. If the image has
% a depth greater than 8, the depth is reduced. If transparency
% is present, the tRNS chunk must only have values 0 and 255
% (i.e., transparency is binary: fully opaque or fully
% transparent). If other values are present they will be
% 50%-thresholded to binary transparency. If more than 256
% colors are present, they will be quantized to the 4-4-4-1,
% 3-3-3-1, or 3-3-2-1 palette. The underlying RGB color
% of any resulting fully-transparent pixels is changed to
% the image's background color.
%
% If you want better quantization or dithering of the colors
% or alpha than that, you need to do it before calling the
% PNG encoder. The pixels contain 8-bit indices even if
% they could be represented with 1, 2, or 4 bits. Grayscale
% images will be written as indexed PNG files even though the
% PNG grayscale type might be slightly more efficient. Please
% note that writing to the PNG8 format may result in loss
% of color and alpha data.
%
% o PNG24: An 8-bit per sample RGB PNG datastream is written. The tRNS
% chunk can be present to convey binary transparency by naming
% one of the colors as transparent. The only loss incurred
% is reduction of sample depth to 8. If the image has more
% than one transparent color, has semitransparent pixels, or
% has an opaque pixel with the same RGB components as the
% transparent color, an image is not written.
%
% o PNG32: An 8-bit per sample RGBA PNG is written. Partial
% transparency is permitted, i.e., the alpha sample for
% each pixel can have any value from 0 to 255. The alpha
% channel is present even if the image is fully opaque.
% The only loss in data is the reduction of the sample depth
% to 8.
%
% o PNG48: A 16-bit per sample RGB PNG datastream is written. The tRNS
% chunk can be present to convey binary transparency by naming
% one of the colors as transparent. If the image has more
% than one transparent color, has semitransparent pixels, or
% has an opaque pixel with the same RGB components as the
% transparent color, an image is not written.
%
% o PNG64: A 16-bit per sample RGBA PNG is written. Partial
% transparency is permitted, i.e., the alpha sample for
% each pixel can have any value from 0 to 65535. The alpha
% channel is present even if the image is fully opaque.
%
% o PNG00: A PNG that inherits its colortype and bit-depth from the input
% image, if the input was a PNG, is written. If these values
% cannot be found, or if the pixels have been changed in a way
% that makes this impossible, then "PNG00" falls back to the
% regular "PNG" format.
%
% o -define: For more precise control of the PNG output, you can use the
% Image options "png:bit-depth" and "png:color-type". These
% can be set from the commandline with "-define" and also
% from the application programming interfaces. The options
% are case-independent and are converted to lowercase before
% being passed to this encoder.
%
% png:color-type can be 0, 2, 3, 4, or 6.
%
% When png:color-type is 0 (Grayscale), png:bit-depth can
% be 1, 2, 4, 8, or 16.
%
% When png:color-type is 2 (RGB), png:bit-depth can
% be 8 or 16.
%
% When png:color-type is 3 (Indexed), png:bit-depth can
% be 1, 2, 4, or 8. This refers to the number of bits
% used to store the index. The color samples always have
% bit-depth 8 in indexed PNG files.
%
% When png:color-type is 4 (Gray-Matte) or 6 (RGB-Matte),
% png:bit-depth can be 8 or 16.
%
% If the image cannot be written without loss with the
% requested bit-depth and color-type, a PNG file will not
% be written, a warning will be issued, and the encoder will
% return MagickFalse.
%
% Since image encoders should not be responsible for the "heavy lifting",
% the user should make sure that ImageMagick has already reduced the
% image depth and number of colors and limit transparency to binary
% transparency prior to attempting to write the image with depth, color,
% or transparency limitations.
%
% To do: Enforce the previous paragraph.
%
% Note that another definition, "png:bit-depth-written" exists, but it
% is not intended for external use. It is only used internally by the
% PNG encoder to inform the JNG encoder of the depth of the alpha channel.
%
% It is possible to request that the PNG encoder write previously-formatted
% ancillary chunks in the output PNG file, using the "-profile" commandline
% option as shown below or by setting the profile via a programming
% interface:
%
% -profile PNG-chunk-x:<file>
%
% where x is a location flag and <file> is a file containing the chunk
% name in the first 4 bytes, then a colon (":"), followed by the chunk data.
% This encoder will compute the chunk length and CRC, so those must not
% be included in the file.
%
% "x" can be "b" (before PLTE), "m" (middle, i.e., between PLTE and IDAT),
% or "e" (end, i.e., after IDAT). If you want to write multiple chunks
% of the same type, then add a short unique string after the "x" to prevent
% subsequent profiles from overwriting the preceding ones, e.g.,
%
% -profile PNG-chunk-b01:file01 -profile PNG-chunk-b02:file02
%
% As of version 6.6.6 the following optimizations are always done:
%
% o 32-bit depth is reduced to 16.
% o 16-bit depth is reduced to 8 if all pixels contain samples whose
% high byte and low byte are identical.
% o Palette is sorted to remove unused entries and to put a
% transparent color first, if BUILD_PNG_PALETTE is defined.
% o Opaque matte channel is removed when writing an indexed PNG.
% o Grayscale images are reduced to 1, 2, or 4 bit depth if
% this can be done without loss and a larger bit depth N was not
% requested via the "-define png:bit-depth=N" option.
% o If matte channel is present but only one transparent color is
% present, RGB+tRNS is written instead of RGBA
% o Opaque matte channel is removed (or added, if color-type 4 or 6
% was requested when converting an opaque image).

/* Check for chunks to be excluded:
*
* The default is to not exclude any known chunks except for any
* listed in the "unused_chunks" array, above.
*
* Chunks can be listed for exclusion via a "png:exclude-chunk"
* define (in the image properties or in the image artifacts)
* or via a mng_info member. For convenience, in addition
* to or instead of a comma-separated list of chunks, the
* "exclude-chunk" string can be simply "all" or "none".
*
* The exclude-chunk define takes priority over the mng_info.
*
* A "png:include-chunk" define takes priority over both the
* mng_info and the "png:exclude-chunk" define. Like the
* "exclude-chunk" string, it can define "all" or "none" as
* well as a comma-separated list. Chunks that are unknown to
* ImageMagick are always excluded, regardless of their "copy-safe"
* status according to the PNG specification, and even if they
* appear in the "include-chunk" list. Such defines appearing among
* the image options take priority over those found among the image
* artifacts.
*
* Finally, all chunks listed in the "unused_chunks" array are
* automatically excluded, regardless of the other instructions
* or lack thereof.
*
* if you exclude sRGB but not gAMA (recommended), then sRGB chunk
* will not be written and the gAMA chunk will only be written if it
* is not between .45 and .46, or approximately (1.0/2.2).
*
* If you exclude tRNS and the image has transparency, the colortype
* is forced to be 4 or 6 (GRAY_ALPHA or RGB_ALPHA).
*
* The -strip option causes StripImage() to set the png:include-chunk
* artifact to "none,trns,gama".

*
* SunOS 5.x core files contain two PT_NOTE sections, with the types

* same info about the command name and command line, so it probably
* isn't worthwhile to look for NT_PSINFO, but the offsets are provided
* above (see USE_NT_PSINFO), in case we ever decide to do so. The
* NT_PRPSINFO and NT_PSINFO sections are always in order and adjacent;
* the SunOS 5.x file command relies on this (and prefers the latter).
*
* The signal number probably appears in a section of type NT_PRSTATUS,
* but that's also rather OS-dependent, in ways that are harder to
* dissect with heuristics, so I'm not bothering with the signal number.
* (I suppose the signal number could be of interest in situations where
* you don't have the binary of the program that dropped core; if you
* *do* have that binary, the debugger will probably tell you what

* Avoid heap allocation at all costs to ensure that the trio functions

* by design are required to allocate form the heap.

************************************************************************/
/*
* TODO:
* - Scan is probably too permissive about its modifiers.
* - C escapes in %#[] ?
* - Multibyte characters (done for format parsing, except scan groups)
* - Complex numbers? (C99 _Complex)
* - Boolean values? (C99 _Bool)
* - C99 NaN(n-char-sequence) missing. The n-char-sequence can be used
* to print the mantissa, e.g. NaN(0xc000000000000000)
* - Should we support the GNU %a alloc modifier? GNU has an ugly hack
* for %a, because C99 used %a for other purposes. If specified as
* %as or %a[ it is interpreted as the alloc modifier, otherwise as
* the C99 hex-float. This means that you cannot scan %as as a hex-float
* immediately followed by an 's'.

% o exception: return any errors or warnings in this structure.
%
% To do, more or less in chronological order (as of version 5.5.2,
% November 26, 2002 -- glennrp -- see also "To do" under WriteMNGImage):
%
% Get 16-bit cheap transparency working.
%
% (At this point, PNG decoding is supposed to be in full MNG-LC compliance)
%
% Preserve all unknown and not-yet-handled known chunks found in input
% PNG file and copy them into output PNG files according to the PNG
% copying rules.
%
% (At this point, PNG encoding should be in full MNG compliance)
%
% Provide options for choice of background to use when the MNG BACK
% chunk is not present or is not mandatory (i.e., leave transparent,
% user specified, MNG BACK, PNG bKGD)
%
% Implement LOOP/ENDL [done, but could do discretionary loops more
% efficiently by linking in the duplicate frames.].
%
% Decode and act on the MHDR simplicity profile (offer option to reject
% files or attempt to process them anyway when the profile isn't LC or VLC).
%
% Upgrade to full MNG without Delta-PNG.
%
% o BACK [done a while ago except for background image ID]
% o MOVE [done 15 May 1999]
% o CLIP [done 15 May 1999]
% o DISC [done 19 May 1999]
% o SAVE [partially done 19 May 1999 (marks objects frozen)]
% o SEEK [partially done 19 May 1999 (discard function only)]
% o SHOW
% o PAST
% o BASI
% o MNG-level tEXt/iTXt/zTXt
% o pHYg
% o pHYs
% o sBIT
% o bKGD
% o iTXt (wait for libpng implementation).
%
% Use the scene signature to discover when an identical scene is
% being reused, and just point to the original image->exception instead
% of storing another set of pixels. This not specific to MNG
% but could be applied generally.
%
% Upgrade to full MNG with Delta-PNG.
%
% JNG tEXt/iTXt/zTXt
%
% We will not attempt to read files containing the CgBI chunk.
% They are really Xcode files meant for display on the iPhone.
% These are not valid PNG files and it is impossible to recover
% the original PNG from files that have been converted to Xcode-PNG,
% since irretrievable loss of color data has occurred due to the
% use of premultiplied alpha.

% WriteMNGImage() writes an image in the Portable Network Graphics
% Group's "Multiple-image Network Graphics" encoded image format.

%
% The format of the WriteMNGImage method is:
%
% MagickBooleanType WriteMNGImage(const ImageInfo *image_info,Image *image)
%
% A description of each parameter follows.
%
% o image_info: the image info.
%
% o image: The image.
%
%
% To do (as of version 5.5.2, November 26, 2002 -- glennrp -- see also
% "To do" under ReadPNGImage):
%
% Preserve all unknown and not-yet-handled known chunks found in input
% PNG file and copy them into output PNG files according to the PNG
% copying rules.
%
% Write the iCCP chunk at MNG level when (icc profile length > 0)
%
% Improve selection of color type (use indexed-colour or indexed-colour
% with tRNS when 256 or fewer unique RGBA values are present).
%
% Figure out what to do with "dispose=<restore-to-previous>" (dispose == 3)
% This will be complicated if we limit ourselves to generating MNG-LC
% files. For now we ignore disposal method 3 and simply overlay the next
% image on it.
%
% Check for identical PLTE's or PLTE/tRNS combinations and use a
% global MNG PLTE or PLTE/tRNS combination when appropriate.
% [mostly done 15 June 1999 but still need to take care of tRNS]
%
% Check for identical sRGB and replace with a global sRGB (and remove
% gAMA/cHRM if sRGB is found; check for identical gAMA/cHRM and
% replace with global gAMA/cHRM (or with sRGB if appropriate; replace
% local gAMA/cHRM with local sRGB if appropriate).
%
% Check for identical sBIT chunks and write global ones.
%
% Provide option to skip writing the signature tEXt chunks.
%
% Use signatures to detect identical objects and reuse the first
% instance of such objects instead of writing duplicate objects.
%
% Use a smaller-than-32k value of compression window size when
% appropriate.
%
% Encode JNG datastreams. Mostly done as of 5.5.2; need to write
% ancillary text chunks and save profiles.
%
% Provide an option to force LC files (to ensure exact framing rate)
% instead of VLC.
%
% Provide an option to force VLC files instead of LC, even when offsets
% are present. This will involve expanding the embedded images with a
% transparent region at the top and/or left.

%
% WritePNGImage() writes a Portable Network Graphics (PNG) or
% Multiple-image Network Graphics (MNG) image file.
%
% MNG support written by Glenn Randers-Pehrson, glennrp@image...
%
% The format of the WritePNGImage method is:
%
% MagickBooleanType WritePNGImage(const ImageInfo *image_info,Image *image)
%
% A description of each parameter follows:
%
% o image_info: the image info.
%
% o image: The image.
%
% Returns MagickTrue on success, MagickFalse on failure.
%
% Communicating with the PNG encoder:
%
% While the datastream written is always in PNG format and normally would
% be given the "png" file extension, this method also writes the following
% pseudo-formats which are subsets of png:
%
% o PNG8: An 8-bit indexed PNG datastream is written. If the image has
% a depth greater than 8, the depth is reduced. If transparency
% is present, the tRNS chunk must only have values 0 and 255
% (i.e., transparency is binary: fully opaque or fully
% transparent). If other values are present they will be
% 50%-thresholded to binary transparency. If more than 256
% colors are present, they will be quantized to the 4-4-4-1,
% 3-3-3-1, or 3-3-2-1 palette. The underlying RGB color
% of any resulting fully-transparent pixels is changed to
% the image's background color.
%
% If you want better quantization or dithering of the colors
% or alpha than that, you need to do it before calling the
% PNG encoder. The pixels contain 8-bit indices even if
% they could be represented with 1, 2, or 4 bits. Grayscale
% images will be written as indexed PNG files even though the
% PNG grayscale type might be slightly more efficient. Please
% note that writing to the PNG8 format may result in loss
% of color and alpha data.
%
% o PNG24: An 8-bit per sample RGB PNG datastream is written. The tRNS
% chunk can be present to convey binary transparency by naming
% one of the colors as transparent. The only loss incurred
% is reduction of sample depth to 8. If the image has more
% than one transparent color, has semitransparent pixels, or
% has an opaque pixel with the same RGB components as the
% transparent color, an image is not written.
%
% o PNG32: An 8-bit per sample RGBA PNG is written. Partial
% transparency is permitted, i.e., the alpha sample for
% each pixel can have any value from 0 to 255. The alpha
% channel is present even if the image is fully opaque.
% The only loss in data is the reduction of the sample depth
% to 8.
%
% o PNG48: A 16-bit per sample RGB PNG datastream is written. The tRNS
% chunk can be present to convey binary transparency by naming
% one of the colors as transparent. If the image has more
% than one transparent color, has semitransparent pixels, or
% has an opaque pixel with the same RGB components as the
% transparent color, an image is not written.
%
% o PNG64: A 16-bit per sample RGBA PNG is written. Partial
% transparency is permitted, i.e., the alpha sample for
% each pixel can have any value from 0 to 65535. The alpha
% channel is present even if the image is fully opaque.
%
% o PNG00: A PNG that inherits its colortype and bit-depth from the input
% image, if the input was a PNG, is written. If these values
% cannot be found, or if the pixels have been changed in a way
% that makes this impossible, then "PNG00" falls back to the
% regular "PNG" format.
%
% o -define: For more precise control of the PNG output, you can use the
% Image options "png:bit-depth" and "png:color-type". These
% can be set from the commandline with "-define" and also
% from the application programming interfaces. The options
% are case-independent and are converted to lowercase before
% being passed to this encoder.
%
% png:color-type can be 0, 2, 3, 4, or 6.
%
% When png:color-type is 0 (Grayscale), png:bit-depth can
% be 1, 2, 4, 8, or 16.
%
% When png:color-type is 2 (RGB), png:bit-depth can
% be 8 or 16.
%
% When png:color-type is 3 (Indexed), png:bit-depth can
% be 1, 2, 4, or 8. This refers to the number of bits
% used to store the index. The color samples always have
% bit-depth 8 in indexed PNG files.
%
% When png:color-type is 4 (Gray-Matte) or 6 (RGB-Matte),
% png:bit-depth can be 8 or 16.
%
% If the image cannot be written without loss with the
% requested bit-depth and color-type, a PNG file will not
% be written, a warning will be issued, and the encoder will
% return MagickFalse.
%
% Since image encoders should not be responsible for the "heavy lifting",
% the user should make sure that ImageMagick has already reduced the
% image depth and number of colors and limit transparency to binary
% transparency prior to attempting to write the image with depth, color,
% or transparency limitations.
%
% To do: Enforce the previous paragraph.
%
% Note that another definition, "png:bit-depth-written" exists, but it
% is not intended for external use. It is only used internally by the
% PNG encoder to inform the JNG encoder of the depth of the alpha channel.
%
% It is possible to request that the PNG encoder write previously-formatted
% ancillary chunks in the output PNG file, using the "-profile" commandline
% option as shown below or by setting the profile via a programming
% interface:
%
% -profile PNG-chunk-x:<file>
%
% where x is a location flag and <file> is a file containing the chunk
% name in the first 4 bytes, then a colon (":"), followed by the chunk data.
% This encoder will compute the chunk length and CRC, so those must not
% be included in the file.
%
% "x" can be "b" (before PLTE), "m" (middle, i.e., between PLTE and IDAT),
% or "e" (end, i.e., after IDAT). If you want to write multiple chunks
% of the same type, then add a short unique string after the "x" to prevent
% subsequent profiles from overwriting the preceding ones, e.g.,
%
% -profile PNG-chunk-b01:file01 -profile PNG-chunk-b02:file02
%
% As of version 6.6.6 the following optimizations are always done:
%
% o 32-bit depth is reduced to 16.
% o 16-bit depth is reduced to 8 if all pixels contain samples whose
% high byte and low byte are identical.
% o Palette is sorted to remove unused entries and to put a
% transparent color first, if BUILD_PNG_PALETTE is defined.
% o Opaque matte channel is removed when writing an indexed PNG.
% o Grayscale images are reduced to 1, 2, or 4 bit depth if
% this can be done without loss and a larger bit depth N was not
% requested via the "-define png:bit-depth=N" option.
% o If matte channel is present but only one transparent color is
% present, RGB+tRNS is written instead of RGBA
% o Opaque matte channel is removed (or added, if color-type 4 or 6
% was requested when converting an opaque image).

*
* The exclude-chunk define takes priority over the mng_info.

* "exclude-chunk" string, it can define "all" or "none" as
* well as a comma-separated list. Chunks that are unknown to
* ImageMagick are always excluded, regardless of their "copy-safe"
* status according to the PNG specification, and even if they
* appear in the "include-chunk" list. Such defines appearing among
* the image options take priority over those found among the image

*
* if you exclude sRGB but not gAMA (recommended), then sRGB chunk
* will not be written and the gAMA chunk will only be written if it
* is not between .45 and .46, or approximately (1.0/2.2).
*
* If you exclude tRNS and the image has transparency, the colortype
* is forced to be 4 or 6 (GRAY_ALPHA or RGB_ALPHA).

% ImportQuantumPixels() transfers one or more pixel components from a user
% supplied buffer into the image pixel cache of an image. The pixels are
% expected in network byte order. It returns MagickTrue if the pixels are
% successfully transferred, otherwise MagickFalse.
%
% The format of the ImportQuantumPixels method is:
%
% size_t ImportQuantumPixels(const Image *image,CacheView *image_view,
% QuantumInfo *quantum_info,const QuantumType quantum_type,
% const unsigned char *magick_restrict pixels,ExceptionInfo *exception)
%
% A description of each parameter follows:
%
% o image: the image.
%
% o image_view: the image cache view.
%
% o quantum_info: the quantum info.
%
% o quantum_type: Declare which pixel components to transfer (red, green,
% blue, opacity, RGB, or RGBA).
%
% o pixels: The pixel components are transferred from this buffer.
%
% o exception: return any errors or warnings in this structure.

/*
Composition based on the SVG specification:
A Composition is defined by...
Color Function : f(Sc,Dc) where Sc and Dc are the normizalized colors
Blending areas : X = 1 for area of overlap, ie: f(Sc,Dc)
Y = 1 for source preserved
Z = 1 for canvas preserved
Conversion to transparency (then optimized)
Dca' = f(Sc, Dc)*Sa*Da + Y*Sca*(1-Da) + Z*Dca*(1-Sa)
Da' = X*Sa*Da + Y*Sa*(1-Da) + Z*Da*(1-Sa)
Where...
Sca = Sc*Sa normalized Source color divided by Source alpha
Dca = Dc*Da normalized Dest color divided by Dest alpha
Dc' = Dca'/Da' the desired color value for this channel.
Da' in in the follow formula as 'gamma' The resulting alpla value.
Most functions use a blending mode of over (X=1,Y=1,Z=1) this results in
the following optimizations...
gamma = Sa+Da-Sa*Da;
gamma = 1 - QuantumScale*alpha * QuantumScale*beta;
opacity = QuantumScale*alpha*beta; // over blend, optimized 1-Gamma
The above SVG definitions also define that Mathematical Composition
methods should use a 'Over' blending mode for Alpha Channel.
It however was not applied for composition modes of 'Plus', 'Minus',
the modulus versions of 'Add' and 'Subtract'.
Mathematical operator changes to be applied from IM v6.7...
1) Modulus modes 'Add' and 'Subtract' are obsoleted and renamed
'ModulusAdd' and 'ModulusSubtract' for clarity.
2) All mathematical compositions work as per the SVG specification
with regard to blending. This now includes 'ModulusAdd' and
'ModulusSubtract'.
3) When the special channel flag 'sync' (syncronize channel updates)
is turned off (enabled by default) then mathematical compositions are
only performed on the channels specified, and are applied
independantally of each other. In other words the mathematics is
performed as 'pure' mathematical operations, rather than as image
operations.

#ifdef LOGLUV_SUPPORT
/*
* TIFF Library.
* LogLuv compression support for high dynamic range images.
*
* Contributed by Greg Larson.
*
* LogLuv image support uses the TIFF library to store 16 or 10-bit
* log luminance values with 8 bits each of u and v or a 14-bit index.
*
* The codec can take as input and produce as output 32-bit IEEE float values
* as well as 16-bit integer values. A 16-bit luminance is interpreted
* as a sign bit followed by a 15-bit integer that is converted
* to and from a linear magnitude using the transformation:
*
* L = 2^( (Le+.5)/256 - 64 ) # real from 15-bit
*
* Le = floor( 256*(log2(L) + 64) ) # 15-bit from real
*
* The actual conversion to world luminance units in candelas per sq. meter
* requires an additional multiplier, which is stored in the TIFFTAG_STONITS.
* This value is usually set such that a reasonable exposure comes from
* clamping decoded luminances above 1 to 1 in the displayed image.
*
* The 16-bit values for u and v may be converted to real values by dividing
* each by 32768. (This allows for negative values, which aren't useful as
* far as we know, but are left in case of future improvements in human
* color vision.)
*
* Conversion from (u,v), which is actually the CIE (u',v') system for
* you color scientists, is accomplished by the following transformation:
*
* u = 4*x / (-2*x + 12*y + 3)
* v = 9*y / (-2*x + 12*y + 3)
*
* x = 9*u / (6*u - 16*v + 12)
* y = 4*v / (6*u - 16*v + 12)
*
* This process is greatly simplified by passing 32-bit IEEE floats
* for each of three CIE XYZ coordinates. The codec then takes care
* of conversion to and from LogLuv, though the application is still
* responsible for interpreting the TIFFTAG_STONITS calibration factor.
*
* By definition, a CIE XYZ vector of [1 1 1] corresponds to a neutral white
* point of (x,y)=(1/3,1/3). However, most color systems assume some other
* white point, such as D65, and an absolute color conversion to XYZ then
* to another color space with a different white point may introduce an
* unwanted color cast to the image. It is often desirable, therefore, to
* perform a white point conversion that maps the input white to [1 1 1]
* in XYZ, then record the original white point using the TIFFTAG_WHITEPOINT
* tag value. A decoder that demands absolute color calibration may use
* this white point tag to get back the original colors, but usually it
* will be ignored and the new white point will be used instead that
* matches the output color space.
*
* Pixel information is compressed into one of two basic encodings, depending
* on the setting of the compression tag, which is one of COMPRESSION_SGILOG
* or COMPRESSION_SGILOG24. For COMPRESSION_SGILOG, greyscale data is
* stored as:
*
* 1 15
* |-+---------------|
*
* COMPRESSION_SGILOG color data is stored as:
*
* 1 15 8 8
* |-+---------------|--------+--------|
* S Le ue ve
*
* For the 24-bit COMPRESSION_SGILOG24 color format, the data is stored as:
*
* 10 14
* |----------|--------------|
* Le' Ce
*
* There is no sign bit in the 24-bit case, and the (u,v) chromaticity is
* encoded as an index for optimal color resolution. The 10 log bits are
* defined by the following conversions:
*
* L = 2^((Le'+.5)/64 - 12) # real from 10-bit
*
* Le' = floor( 64*(log2(L) + 12) ) # 10-bit from real
*
* The 10 bits of the smaller format may be converted into the 15 bits of
* the larger format by multiplying by 4 and adding 13314. Obviously,
* a smaller range of magnitudes is covered (about 5 orders of magnitude
* instead of 38), and the lack of a sign bit means that negative luminances
* are not allowed. (Well, they aren't allowed in the real world, either,
* but they are useful for certain types of image processing.)
*
* The desired user format is controlled by the setting the internal
* pseudo tag TIFFTAG_SGILOGDATAFMT to one of:
* SGILOGDATAFMT_FLOAT = IEEE 32-bit float XYZ values
* SGILOGDATAFMT_16BIT = 16-bit integer encodings of logL, u and v
* Raw data i/o is also possible using:
* SGILOGDATAFMT_RAW = 32-bit unsigned integer with encoded pixel
* In addition, the following decoding is provided for ease of display:
* SGILOGDATAFMT_8BIT = 8-bit default RGB gamma-corrected values
*
* For grayscale images, we provide the following data formats:
* SGILOGDATAFMT_FLOAT = IEEE 32-bit float Y values
* SGILOGDATAFMT_16BIT = 16-bit integer w/ encoded luminance
* SGILOGDATAFMT_8BIT = 8-bit gray monitor values
*
* Note that the COMPRESSION_SGILOG applies a simple run-length encoding
* scheme by separating the logL, u and v bytes for each row and applying
* a PackBits type of compression. Since the 24-bit encoding is not
* adaptive, the 32-bit color format takes less space in many cases.
*
* Further control is provided over the conversion from higher-resolution
* formats to final encoded values through the pseudo tag
* TIFFTAG_SGILOGENCODE:
* SGILOGENCODE_NODITHER = do not dither encoded values
* SGILOGENCODE_RANDITHER = apply random dithering during encoding
*
* The default value of this tag is SGILOGENCODE_NODITHER for
* COMPRESSION_SGILOG to maximize run-length encoding and
* SGILOGENCODE_RANDITHER for COMPRESSION_SGILOG24 to turn
* quantization errors into noise.

*
* That was what the original tcpdump code did.
*
* FreeBSD's "if_ppp.c" *does* set the first octet to 1 for outbound
* packets and 0 for inbound packets - but only if the
* protocol field has the 0x8000 bit set (i.e., it's a network
* control protocol); it does so before running the packet through
* "bpf_filter" to see if it should be discarded, and to see
* if we should update the time we sent the most recent packet...
*
* ...but it puts the original address field back after doing
* so.
*
* NetBSD's "if_ppp.c" doesn't set the first octet in that fashion.
*
* I don't know if any PPP implementation handed up to a BPF
* device packets with the first octet being 1 for outbound and
* 0 for inbound packets, so I (guy@alum.mit.edu) don't know
* whether that ever needs to be checked or not.
*
* Note that NetBSD has a DLT_PPP_SERIAL, which it uses for PPP,
* and its tcpdump appears to assume that the frame always
* begins with an address field and a control field, and that
* the address field might be 0x0f or 0x8f, for Cisco
* point-to-point with HDLC framing as per section 4.3.1 of RFC
* 1547, as well as 0xff, for PPP in HDLC-like framing as per

* (mshindo@mshindo.net).
*
* That was what the original tcpdump code did.
*
* FreeBSD's "if_ppp.c" *does* set the first octet to 1 for outbound
* packets and 0 for inbound packets - but only if the
* protocol field has the 0x8000 bit set (i.e., it's a network
* control protocol); it does so before running the packet through
* "bpf_filter" to see if it should be discarded, and to see
* if we should update the time we sent the most recent packet...
*
* ...but it puts the original address field back after doing
* so.
*
* NetBSD's "if_ppp.c" doesn't set the first octet in that fashion.
*
* I don't know if any PPP implementation handed up to a BPF
* device packets with the first octet being 1 for outbound and
* 0 for inbound packets, so I (guy@alum.mit.edu) don't know
* whether that ever needs to be checked or not.
*
* Note that NetBSD has a DLT_PPP_SERIAL, which it uses for PPP,
* and its tcpdump appears to assume that the frame always
* begins with an address field and a control field, and that
* the address field might be 0x0f or 0x8f, for Cisco
* point-to-point with HDLC framing as per section 4.3.1 of RFC
* 1547, as well as 0xff, for PPP in HDLC-like framing as per
* RFC 1662.
*
* (Is the Cisco framing in question what DLT_C_HDLC, in
* BSD/OS, is?)
