- gdIOCtx structures hold function pointers for doing image IO.
-
- Most of the gd functions that read and write files, such as
- <gdImagePng> also have variants that accept a <gdIOCtx> structure;
- see <gdImagePngCtx> and <gdImageCreateFromJpegCtx>.
-
- Those who wish to provide their own custom routines to read and
- write images can populate a gdIOCtx structure with functions of
- their own devising to to read and write data. For image reading, the
- only mandatory functions are getC and getBuf, which must return the
- number of characters actually read, or a negative value on error or
- EOF. These functions must read the number of characters requested
- unless at the end of the file.
-
- For image writing, the only mandatory functions are putC and putBuf,
- which return the number of characters written; these functions must
- write the number of characters requested except in the event of an
- error. The seek and tell functions are only required in conjunction
- with the gd2 file format, which supports quick loading of partial
- images. The gd_free function will not be invoked when calling the
- standard Ctx functions; it is an implementation convenience when
- adding new data types to gd. For examples, see gd_png.c, gd_gd2.c,
- gd_jpeg.c, etc., all of which rely on gdIOCtx to implement the
- standard image read and write functions.

- * John Ellson (ellson@graphviz.org) Oct 31, 1997
- *
- * Test this with:
- * gcc -o gdcache -g -Wall -DTEST gdcache.c
- *
- * The cache is implemented by a singly-linked list of elements
- * each containing a pointer to a user struct that is being managed by
- * the cache.
- *
- * The head structure has a pointer to the most-recently-used
- * element, and elements are moved to this position in the list each
- * time they are used. The head also contains pointers to three
- * user defined functions:
- * - a function to test if a cached userdata matches some keydata
- * - a function to provide a new userdata struct to the cache
- * if there has been a cache miss.
- * - a function to release a userdata struct when it is
- * no longer being managed by the cache
- *
- * In the event of a cache miss the cache is allowed to grow up to
- * a specified maximum size. After the maximum size is reached then
- * the least-recently-used element is discarded to make room for the
- * new. The most-recently-returned value is always left at the
- * beginning of the list after retrieval.
- *
- * In the current implementation the cache is traversed by a linear
- * search from most-recent to least-recent. This linear search
- * probably limits the usefulness of this implementation to cache
- * sizes of a few tens of elements.

- * Henceforth the source version will match the shared-library major

- * PNG_LIBPNG_VER macro, which is not used within libpng but is available
- * for applications, is an unsigned integer of the form xyyzz corresponding
- * to the source version x.y.z (leading zeros in y and z). Beta versions
- * were given the previous public release number plus a letter, until
- * version 1.0.6j; from then on they were given the upcoming public
- * release number plus "betaNN" or "rcNN".
- *
- * Binary incompatibility exists only when applications make direct access
- * to the info_ptr or png_ptr members through png.h, and the compiled
- * application is loaded with a different version of the library.
- *
- * DLLNUM will change each time there are forward or backward changes
- * in binary compatibility (e.g., when a new feature is added).
- *
- * See libpng-manual.txt or libpng.3 for more information. The PNG
- * specification is available as a W3C Recommendation and as an ISO

- * Y2K compliance in libpng:
- * =========================
- *
- * December 22, 2014
- *
- * Since the PNG Development group is an ad-hoc body, we can't make
- * an official declaration.
- *
- * This is your unofficial assurance that libpng from version 0.71 and
- * upward through 1.6.16 are Y2K compliant. It is my belief that
- * earlier versions were also Y2K compliant.
- *
- * Libpng only has two year fields. One is a 2-byte unsigned integer
- * that will hold years up to 65535. The other, which is deprecated,
- * holds the date in text format, and will hold years up to 9999.
- *
- * The integer is
- * "png_uint_16 year" in png_time_struct.
- *
- * The string is
- * "char time_buffer[29]" in png_struct. This is no longer used
- * in libpng-1.6.x and will be removed from libpng-1.7.0.
- *
- * There are seven time-related functions:
- * png.c: png_convert_to_rfc_1123_buffer() in png.c
- * (formerly png_convert_to_rfc_1123() prior to libpng-1.5.x and
- * png_convert_to_rfc_1152() in error prior to libpng-0.98)
- * png_convert_from_struct_tm() in pngwrite.c, called in pngwrite.c
- * png_convert_from_time_t() in pngwrite.c
- * png_get_tIME() in pngget.c
- * png_handle_tIME() in pngrutil.c, called in pngread.c
- * png_set_tIME() in pngset.c
- * png_write_tIME() in pngwutil.c, called in pngwrite.c
- *
- * All handle dates properly in a Y2K environment. The
- * png_convert_from_time_t() function calls gmtime() to convert from system
- * clock time, which returns (year - 1900), which we properly convert to
- * the full 4-digit year. There is a possibility that libpng applications
- * are not passing 4-digit years into the png_convert_to_rfc_1123_buffer()
- * function, or that they are incorrectly passing only a 2-digit year
- * instead of "year - 1900" into the png_convert_from_struct_tm() function,
- * but this is not under our control. The libpng documentation has always
- * stated that it works with 4-digit years, and the APIs have been
- * documented as such.
- *
- * The tIME chunk itself is also Y2K compliant. It uses a 2-byte unsigned
- * integer to hold the year, and can hold years as large as 65535.
- *
- * zlib, upon which libpng depends, is also Y2K compliant. It contains
- * no date-related code.

- *
- * png_set_alpha_mode(pp, PNG_ALPHA_STANDARD, PNG_GAMMA_LINEAR);
- * This is the classic Jim Blinn approach and will work in academic
- * environments where everything is done by the book. It has the shortcoming

- * is unlikely to be correct unless the PNG files where generated locally.
- * Most of the time the output precision will be so low as to show
- * significant banding in dark areas of the image.
- *
- * png_set_expand_16(pp);
- * png_set_alpha_mode(pp, PNG_ALPHA_STANDARD, PNG_DEFAULT_sRGB);
- * This is a somewhat more realistic Jim Blinn inspired approach. PNG files
- * are assumed to have the sRGB encoding if not marked with a gamma value and
- * the output is always 16 bits per component. This permits accurate scaling
- * and processing of the data. If you know that your input PNG files were
- * generated locally you might need to replace PNG_DEFAULT_sRGB with the
- * correct value for your system.
- *
- * png_set_alpha_mode(pp, PNG_ALPHA_OPTIMIZED, PNG_DEFAULT_sRGB);
- * If you just need to composite the PNG image onto an existing background
- * and if you control the code that does this you can use the optimization
- * setting. In this case you just copy completely opaque pixels to the
- * output. For pixels that are not completely transparent (you just skip
- * those) you do the composition math using png_composite or png_composite_16
- * below then encode the resultant 8-bit or 16-bit values to match the output
- * encoding.
- *
- * Other cases
- * If neither the PNG nor the standard linear encoding work for you because
- * of the software or hardware you use then you have a big problem. The PNG
- * case will probably result in halos around the image. The linear encoding
- * will probably result in a washed out, too bright, image (it's actually too
- * contrasty.) Try the ALPHA_OPTIMIZED mode above - this will probably
- * substantially reduce the halos. Alternatively try:
- *
- * png_set_alpha_mode(pp, PNG_ALPHA_BROKEN, PNG_DEFAULT_sRGB);
- * This option will also reduce the halos, but there will be slight dark
- * halos round the opaque parts of the image where the background is light.
- * In the OPTIMIZED mode the halos will be light halos where the background
- * is dark. Take your pick - the halos are unavoidable unless you can get
- * your hardware/software fixed! (The OPTIMIZED approach is slightly
- * faster.)
- *
- * When the default gamma of PNG files doesn't match the output gamma.
- * If you have PNG files with no gamma information png_set_alpha_mode allows
- * you to provide a default gamma, but it also sets the ouput gamma to the
- * matching value. If you know your PNG files have a gamma that doesn't
- * match the output you can take advantage of the fact that
- * png_set_alpha_mode always sets the output gamma but only sets the PNG
- * default if it is not already set:
- *
- * png_set_alpha_mode(pp, PNG_ALPHA_PNG, PNG_DEFAULT_sRGB);
- * png_set_alpha_mode(pp, PNG_ALPHA_PNG, PNG_GAMMA_MAC);
- * The first call sets both the default and the output gamma values, the
- * second call overrides the output gamma without changing the default. This
- * is easier than achieving the same effect with png_set_gamma. You must use
- * PNG_ALPHA_PNG for the first call - internal checking in png_set_alpha will
- * fire if more than one call to png_set_alpha_mode and png_set_background is
- * made in the same read operation, however multiple calls with PNG_ALPHA_PNG
- * are ignored.

-/* Provide the default handling for all unknown chunks or, optionally, for
- * specific unknown chunks.
- *
- * NOTE: prior to 1.6.0 the handling specified for particular chunks on read was
- * ignored and the default was used, the per-chunk setting only had an effect on
- * write. If you wish to have chunk-specific handling on read in code that must
- * work on earlier versions you must use a user chunk callback to specify the
- * desired handling (keep or discard.)
- *
- * The 'keep' parameter is a PNG_HANDLE_CHUNK_ value as listed below. The
- * parameter is interpreted as follows:
- *
- * READ:
- * PNG_HANDLE_CHUNK_AS_DEFAULT:
- * Known chunks: do normal libpng processing, do not keep the chunk (but
- * see the comments below about PNG_HANDLE_AS_UNKNOWN_SUPPORTED)
- * Unknown chunks: for a specific chunk use the global default, when used
- * as the default discard the chunk data.
- * PNG_HANDLE_CHUNK_NEVER:
- * Discard the chunk data.
- * PNG_HANDLE_CHUNK_IF_SAFE:
- * Keep the chunk data if the chunk is not critical else raise a chunk
- * error.
- * PNG_HANDLE_CHUNK_ALWAYS:
- * Keep the chunk data.
- *
- * If the chunk data is saved it can be retrieved using png_get_unknown_chunks,
- * below. Notice that specifying "AS_DEFAULT" as a global default is equivalent
- * to specifying "NEVER", however when "AS_DEFAULT" is used for specific chunks
- * it simply resets the behavior to the libpng default.
- *
- * INTERACTION WTIH USER CHUNK CALLBACKS:
- * The per-chunk handling is always used when there is a png_user_chunk_ptr
- * callback and the callback returns 0; the chunk is then always stored *unless*
- * it is critical and the per-chunk setting is other than ALWAYS. Notice that
- * the global default is *not* used in this case. (In effect the per-chunk
- * value is incremented to at least IF_SAFE.)
- *
- * IMPORTANT NOTE: this behavior will change in libpng 1.7 - the global and
- * per-chunk defaults will be honored. If you want to preserve the current
- * behavior when your callback returns 0 you must set PNG_HANDLE_CHUNK_IF_SAFE
- * as the default - if you don't do this libpng 1.6 will issue a warning.
- *
- * If you want unhandled unknown chunks to be discarded in libpng 1.6 and
- * earlier simply return '1' (handled).
- *
- * PNG_HANDLE_AS_UNKNOWN_SUPPORTED:
- * If this is *not* set known chunks will always be handled by libpng and
- * will never be stored in the unknown chunk list. Known chunks listed to
- * png_set_keep_unknown_chunks will have no effect. If it is set then known
- * chunks listed with a keep other than AS_DEFAULT will *never* be processed
- * by libpng, in addition critical chunks must either be processed by the
- * callback or saved.
- *
- * The IHDR and IEND chunks must not be listed. Because this turns off the
- * default handling for chunks that would otherwise be recognized the
- * behavior of libpng transformations may well become incorrect!
- *
- * WRITE:
- * When writing chunks the options only apply to the chunks specified by
- * png_set_unknown_chunks (below), libpng will *always* write known chunks
- * required by png_set_ calls and will always write the core critical chunks
- * (as required for PLTE).
- *
- * Each chunk in the png_set_unknown_chunks list is looked up in the
- * png_set_keep_unknown_chunks list to find the keep setting, this is then
- * interpreted as follows:
- *
- * PNG_HANDLE_CHUNK_AS_DEFAULT:
- * Write safe-to-copy chunks and write other chunks if the global
- * default is set to _ALWAYS, otherwise don't write this chunk.
- * PNG_HANDLE_CHUNK_NEVER:
- * Do not write the chunk.
- * PNG_HANDLE_CHUNK_IF_SAFE:
- * Write the chunk if it is safe-to-copy, otherwise do not write it.
- * PNG_HANDLE_CHUNK_ALWAYS:
- * Write the chunk.
- *
- * Note that the default behavior is effectively the opposite of the read case -
- * in read unknown chunks are not stored by default, in write they are written
- * by default. Also the behavior of PNG_HANDLE_CHUNK_IF_SAFE is very different
- * - on write the safe-to-copy bit is checked, on read the critical bit is
- * checked and on read if the chunk is critical an error will be raised.
- *
- * num_chunks:
- * ===========
- * If num_chunks is positive, then the "keep" parameter specifies the manner
- * for handling only those chunks appearing in the chunk_list array,
- * otherwise the chunk list array is ignored.
- *
- * If num_chunks is 0 the "keep" parameter specifies the default behavior for
- * unknown chunks, as described above.
- *
- * If num_chunks is negative, then the "keep" parameter specifies the manner
- * for handling all unknown chunks plus all chunks recognized by libpng
- * except for the IHDR, PLTE, tRNS, IDAT, and IEND chunks (which continue to

- * SIMPLIFIED API
- *******************************************************************************
- *
- * Please read the documentation in libpng-manual.txt (TODO: write said
- * documentation) if you don't understand what follows.
- *
- * The simplified API hides the details of both libpng and the PNG file format
- * itself. It allows PNG files to be read into a very limited number of
- * in-memory bitmap formats or to be written from the same formats. If these
- * formats do not accomodate your needs then you can, and should, use the more
- * sophisticated APIs above - these support a wide variety of in-memory formats
- * and a wide variety of sophisticated transformations to those formats as well
- * as a wide variety of APIs to manipulate ancillary information.
- *
- * To read a PNG file using the simplified API:
- *
- * 1) Declare a 'png_image' structure (see below) on the stack and set the
- * version field to PNG_IMAGE_VERSION.
- * 2) Call the appropriate png_image_begin_read... function.
- * 3) Set the png_image 'format' member to the required sample format.
- * 4) Allocate a buffer for the image and, if required, the color-map.
- * 5) Call png_image_finish_read to read the image and, if required, the
- * color-map into your buffers.
- *
- * There are no restrictions on the format of the PNG input itself; all valid
- * color types, bit depths, and interlace methods are acceptable, and the
- * input image is transformed as necessary to the requested in-memory format
- * during the png_image_finish_read() step. The only caveat is that if you
- * request a color-mapped image from a PNG that is full-color or makes
- * complex use of an alpha channel the transformation is extremely lossy and the
- * result may look terrible.
- *
- * To write a PNG file using the simplified API:
- *
- * 1) Declare a 'png_image' structure on the stack and memset() it to all zero.
- * 2) Initialize the members of the structure that describe the image, setting
- * the 'format' member to the format of the image samples.
- * 3) Call the appropriate png_image_write... function with a pointer to the
- * image and, if necessary, the color-map to write the PNG data.
- *
- * png_image is a structure that describes the in-memory format of an image
- * when it is being read or defines the in-memory format of an image that you
- * need to write:

- * 2: A gray/luminance channel and an alpha channel (GA).
- * 3: Three red, green, blue color channels (RGB).
- * 4: Three color channels and an alpha channel (RGBA).
- *
- * The components are encoded in one of two ways:
- *
- * a) As a small integer, value 0..255, contained in a single byte. For the
- * alpha channel the original value is simply value/255. For the color or
- * luminance channels the value is encoded according to the sRGB specification
- * and matches the 8-bit format expected by typical display devices.
- *
- * The color/gray channels are not scaled (pre-multiplied) by the alpha
- * channel and are suitable for passing to color management software.
- *
- * b) As a value in the range 0..65535, contained in a 2-byte integer. All
- * channels can be converted to the original value by dividing by 65535; all
- * channels are linear. Color channels use the RGB encoding (RGB end-points) of
- * the sRGB specification. This encoding is identified by the
- * PNG_FORMAT_FLAG_LINEAR flag below.
- *
- * When the simplified API needs to convert between sRGB and linear colorspaces,
- * the actual sRGB transfer curve defined in the sRGB specification (see the
- * article at http://en.wikipedia.org/wiki/SRGB) is used, not the gamma=1/2.2
- * approximation used elsewhere in libpng.
- *
- * When an alpha channel is present it is expected to denote pixel coverage
- * of the color or luminance channels and is returned as an associated alpha
- * channel: the color/gray channels are scaled (pre-multiplied) by the alpha
- * value.
- *
- * The samples are either contained directly in the image data, between 1 and 8
- * bytes per pixel according to the encoding, or are held in a color-map indexed
- * by bytes in the image data. In the case of a color-map the color-map entries
- * are individual samples, encoded as above, and the image data has one byte per
- * pixel to select the relevant sample from the color-map.
- */
-
-/* PNG_FORMAT_*
- *
- * #defines to be used in png_image::format. Each #define identifies a
- * particular layout of sample data and, if present, alpha values. There are
- * separate defines for each of the two component encodings.
- *
- * A format is built up using single bit flag values. All combinations are
- * valid. Formats can be built up from the flag values or you can use one of
- * the predefined values below. When testing formats always use the FORMAT_FLAG
- * macros to test for individual features - future versions of the library may
- * add new flags.
- *
- * When reading or writing color-mapped images the format should be set to the
- * format of the entries in the color-map then png_image_{read,write}_colormap
- * called to read or write the color-map and set the format correctly for the
- * image data. Do not set the PNG_FORMAT_FLAG_COLORMAP bit directly!
- *
- * NOTE: libpng can be built with particular features disabled, if you see
- * compiler errors because the definition of one of the following flags has been
- * compiled out it is because libpng does not have the required support. It is
- * possible, however, for the libpng configuration to enable the format on just
- * read or just write; in that case you may see an error at run time. You can
- * guard against this by checking for the definition of the appropriate

-/* Function calling conventions.
- * =============================
- * Normally it is not necessary to specify to the compiler how to call
- * a function - it just does it - however on x86 systems derived from
- * Microsoft and Borland C compilers ('IBM PC', 'DOS', 'Windows' systems
- * and some others) there are multiple ways to call a function and the
- * default can be changed on the compiler command line. For this reason
- * libpng specifies the calling convention of every exported function and
- * every function called via a user supplied function pointer. This is
- * done in this file by defining the following macros:
- *
- * PNGAPI Calling convention for exported functions.
- * PNGCBAPI Calling convention for user provided (callback) functions.
- * PNGCAPI Calling convention used by the ANSI-C library (required
- * for longjmp callbacks and sometimes used internally to
- * specify the calling convention for zlib).
- *
- * These macros should never be overridden. If it is necessary to
- * change calling convention in a private build this can be done
- * by setting PNG_API_RULE (which defaults to 0) to one of the values
- * below to select the correct 'API' variants.
- *
- * PNG_API_RULE=0 Use PNGCAPI - the 'C' calling convention - throughout.
- * This is correct in every known environment.
- * PNG_API_RULE=1 Use the operating system convention for PNGAPI and
- * the 'C' calling convention (from PNGCAPI) for
- * callbacks (PNGCBAPI). This is no longer required
- * in any known environment - if it has to be used
- * please post an explanation of the problem to the
- * libpng mailing list.
- *
- * These cases only differ if the operating system does not use the C
- * calling convention, at present this just means the above cases
- * (x86 DOS/Windows sytems) and, even then, this does not apply to
- * Cygwin running on those systems.
- *
- * Note that the value must be defined in pnglibconf.h so that what
- * the application uses to call the library matches the conventions
- * set when building the library.
- */
-
-/* Symbol export
- * =============
- * When building a shared library it is almost always necessary to tell
- * the compiler which symbols to export. The png.h macro 'PNG_EXPORT'
- * is used to mark the symbols. On some systems these symbols can be
- * extracted at link time and need no special processing by the compiler,
- * on other systems the symbols are flagged by the compiler and just
- * the declaration requires a special tag applied (unfortunately) in a
- * compiler dependent way. Some systems can do either.
- *
- * A small number of older systems also require a symbol from a DLL to
- * be flagged to the program that calls it. This is a problem because
- * we do not know in the header file included by application code that
- * the symbol will come from a shared library, as opposed to a statically
- * linked one. For this reason the application must tell us by setting
- * the magic flag PNG_USE_DLL to turn on the special processing before
- * it includes png.h.
- *
- * Four additional macros are used to make this happen:
- *
- * PNG_IMPEXP The magic (if any) to cause a symbol to be exported from
- * the build or imported if PNG_USE_DLL is set - compiler
- * and system specific.
- *
- * PNG_EXPORT_TYPE(type) A macro that pre or appends PNG_IMPEXP to
- * 'type', compiler specific.
- *
- * PNG_DLL_EXPORT Set to the magic to use during a libpng build to
- * make a symbol exported from the DLL. Not used in the
- * public header files; see pngpriv.h for how it is used
- * in the libpng build.
- *
- * PNG_DLL_IMPORT Set to the magic to force the libpng symbols to come
- * from a DLL - used to define PNG_IMPEXP when
- * PNG_USE_DLL is set.
- */

-/* System specific discovery.

- * This code is used at build time to find PNG_IMPEXP, the API settings
