f9a51917495bc8ba8b60632219652a7b122c1190vboxsyncversion 0.89 [July, 1996]
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync added new initialization API to make libpng work better with shared libs
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync we now have png_create_read_struct(), png_create_write_struct(),
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync png_create_info_struct(), png_destroy_read_struct(), and
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync png_destroy_write_struct() instead of the separate calls to
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync malloc and png_read_init(), png_info_init(), and png_write_init()
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync changed warning/error callback functions to fix bug - this means you
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync should use the new initialization API if you were using the old
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync png_set_message_fn() calls, and that the old API no longer exists
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync so that people are aware that they need to change their code
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync changed filter selection API to allow selection of multiple filters
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync since it didn't work in previous versions of libpng anyways
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync optimized filter selection code
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync fixed png_set_background() to allow using an arbitrary RGB color for
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync paletted images
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync fixed gamma and background correction for paletted images, so
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync png_correct_palette is not needed unless you are correcting an
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync external palette (you will need to #define PNG_CORRECT_PALETTE_SUPPORTED
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync in pngconf.h) - if nobody uses this, it may disappear in the future.
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync fixed bug with Borland 64K memory allocation (Alexander Lehmann)

f9a51917495bc8ba8b60632219652a7b122c1190vboxsync added more error checking for writing and image to reduce invalid files
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync separated read and write functions so that they won't both be linked
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync into a binary when only reading or writing functionality is used
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync new pngtest image also has interlacing and zTXt
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync updated documentation to reflect new API
f9a51917495bc8ba8b60632219652a7b122c1190vboxsyncversion 0.90 [January, 1997]
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync made CRC errors/warnings on critical and ancillary chunks configurable
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync libpng will use the zlib CRC routines by (compile-time) default
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync changed DOS small/medium model memory support - needs zlib 1.04 (Tim Wegner)
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync added external C++ wrapper statements to png.h (Gilles Dauphin)
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync allow PNG file to be read when some or all of file signature has already
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync been read from the beginning of the stream. ****This affects the size
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync of info_struct and invalidates all programs that use a shared libpng****
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync fixed png_filler() declarations

f9a51917495bc8ba8b60632219652a7b122c1190vboxsync current chunk name is now available in png_struct to reduce the number
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync of nearly identical error messages (will simplify multi-lingual
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync support when available)
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync try to get ready for unknown-chunk callback functions:
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync - previously read critical chunks are flagged, so the chunk handling
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync routines can determine if the chunk is in the right place
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync - all chunk handling routines have the same prototypes, so we will
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync be able to handle all chunks via a callback mechanism
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync try to fix Linux "setjmp" buffer size problems
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync removed png_large_malloc, png_large_free, and png_realloc functions.

f9a51917495bc8ba8b60632219652a7b122c1190vboxsync to png_uint_32
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync added test for MACOS to ensure that both math.h and fp.h are not #included
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync added macros for libpng to be compiled as a Windows DLL (Andreas Kupries)
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync added "packswap" transformation, which changes the endianness of
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync packed-pixel bytes (Kevin Bracey)
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync added "strip_alpha" transformation, which removes the alpha channel of
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync input images without using it (not neccesarily a good idea)
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync added "swap_alpha" transformation, which puts the alpha channel in front
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync of the color bytes instead of after
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync removed all implicit variable tests which assume NULL == 0 (I think)
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync changed several variables to "png_size_t" to show 16/32-bit limitations
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync added new pCAL chunk read/write support

f9a51917495bc8ba8b60632219652a7b122c1190vboxsync removed old png_set_rgbx() and png_set_xrgb() functions that have been
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync obsolete for about 2 years now (use png_set_filler() instead)
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync added macros to read 16- and 32-bit ints directly from buffer, to be
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync used only on those systems that support it (namely PowerPC and 680x0)
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync With some testing, this may become the default for MACOS/PPC systems.
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync only calculate CRC on data if we are going to use it

f9a51917495bc8ba8b60632219652a7b122c1190vboxsync more chunk types tested in pngtest.c
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync renamed pngrcb.c to pngset.c, and all png_read_<chunk> functions to be
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync png_set_<chunk>. We now have corresponding png_get_<chunk>
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync functions in pngget.c to get infomation in info_ptr. This isolates
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync the application from the internal organization of png_info_struct
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync (good for shared library implementations).
f9a51917495bc8ba8b60632219652a7b122c1190vboxsyncversion 0.96 [May, 1997]

f9a51917495bc8ba8b60632219652a7b122c1190vboxsync accomodate making DLL's: Moved usr_png_ver from global variable to function
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync png_get_header_ver() in png.c. Moved png_sig to png_sig_bytes in png.c and
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync eliminated use of png_sig in pngwutil.c. Moved the various png_CHNK arrays
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync into pngtypes.h. Eliminated use of global png_pass arrays. Declared the
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync png_CHNK and png_pass arrays to be "const". Made the global arrays
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync available to applications (although none are used in libpng itself) when
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync PNG_NO_GLOBAL_ARRAYS is not defined or when PNG_GLOBAL_ARRAYS is defined.

f9a51917495bc8ba8b60632219652a7b122c1190vboxsync structure; refactored the inflate/deflate support to make adding new chunks
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync with trailing compressed parts easier in the future, and added new functions
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync png_free_iCCP, png_free_pCAL, png_free_sPLT, png_free_text, png_get_iCCP,

f9a51917495bc8ba8b60632219652a7b122c1190vboxsync NOTE: Applications that write text chunks MUST define png_text->lang
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync before calling png_set_text(). It must be set to NULL if you want to
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync write tEXt or zTXt chunks. If you want your application to be able to
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync run with older versions of libpng, use
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync #ifdef PNG_iTXt_SUPPORTED
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync png_text[i].lang = NULL;

f9a51917495bc8ba8b60632219652a7b122c1190vboxsync offsets (Eric S. Raymond).
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync Combined PNG_READ_cHNK_SUPPORTED and PNG_WRITE_cHNK_SUPPORTED macros into
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync PNG_cHNK_SUPPORTED and combined the three types of PNG_text_SUPPORTED
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync macros, leaving the separate macros also available.
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync Removed comments on #endifs at the end of many short, non-nested #if-blocks.

f9a51917495bc8ba8b60632219652a7b122c1190vboxsync when you define this macro. Capabilities lost in this event
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync are user transforms (new in version 1.0.0),the user transform pointer
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync (new in version 1.0.2), rgb_to_gray (new in 1.0.5), iCCP, sCAL, sPLT,
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync the high-level interface, and unknown chunks support (all new in 1.0.6).
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync This was necessary because of old applications that allocate the structs
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync directly as authors were instructed to do in libpng-0.88 and earlier,
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync instead of using png_create_*().

f9a51917495bc8ba8b60632219652a7b122c1190vboxsync can be used to detect codes that directly allocate the structs, and
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync code to check these modes in png_read_init() and png_write_init() and
f9a51917495bc8ba8b60632219652a7b122c1190vboxsync generate a libpng error if the modes aren't set and PNG_LEGACY_SUPPORTED
