-version 0.81 [August, 1995]
- incorporated Tim Wegner's medium model code (thanks, Tim)
-
-version 0.82 [September, 1995]
- [unspecified changes]
-
-version 0.85 [December, 1995]
- added more medium model code (almost everything's a far)
- added i/o, error, and memory callback functions
- fixed some bugs (16 bit, 4 bit interlaced, etc.)
- added first run progressive reader (barely tested)
-
-version 0.86 [January, 1996]
- fixed bugs
- improved documentation
-
-version 0.87 [January, 1996]
- fixed medium model bugs
- fixed other bugs introduced in 0.85 and 0.86
- added some minor documentation
-
-version 0.88 [January, 1996]
- fixed progressive bugs
- replaced tabs with spaces
- cleaned up documentation
- added callbacks for read/write and warning/error functions
-
-version 0.89 [July, 1996]
- added new initialization API to make libpng work better with shared libs
- we now have png_create_read_struct(), png_create_write_struct(),
- png_create_info_struct(), png_destroy_read_struct(), and
- png_destroy_write_struct() instead of the separate calls to
- malloc and png_read_init(), png_info_init(), and png_write_init()
- changed warning/error callback functions to fix bug - this means you
- should use the new initialization API if you were using the old
- png_set_message_fn() calls, and that the old API no longer exists
- so that people are aware that they need to change their code
- changed filter selection API to allow selection of multiple filters
- since it didn't work in previous versions of libpng anyways
- optimized filter selection code
- fixed png_set_background() to allow using an arbitrary RGB color for
- paletted images
- fixed gamma and background correction for paletted images, so
- png_correct_palette is not needed unless you are correcting an
- external palette (you will need to #define PNG_CORRECT_PALETTE_SUPPORTED
- in pngconf.h) - if nobody uses this, it may disappear in the future.
- fixed bug with Borland 64K memory allocation (Alexander Lehmann)
- fixed bug in interlace handling (Smarasderagd, I think)
- added more error checking for writing and image to reduce invalid files
- separated read and write functions so that they won't both be linked
- into a binary when only reading or writing functionality is used
- new pngtest image also has interlacing and zTXt
- updated documentation to reflect new API
-
-version 0.90 [January, 1997]
- made CRC errors/warnings on critical and ancillary chunks configurable
- libpng will use the zlib CRC routines by (compile-time) default
- changed DOS small/medium model memory support - needs zlib 1.04 (Tim Wegner)
- added external C++ wrapper statements to png.h (Gilles Dauphin)
- allow PNG file to be read when some or all of file signature has already
- been read from the beginning of the stream. ****This affects the size
- of info_struct and invalidates all programs that use a shared libpng****
- fixed png_filler() declarations
- fixed? background color conversions
- fixed order of error function pointers to match documentation
- current chunk name is now available in png_struct to reduce the number
- of nearly identical error messages (will simplify multi-lingual
- support when available)
- try to get ready for unknown-chunk callback functions:
- - previously read critical chunks are flagged, so the chunk handling
- routines can determine if the chunk is in the right place
- - all chunk handling routines have the same prototypes, so we will
- be able to handle all chunks via a callback mechanism
- try to fix Linux "setjmp" buffer size problems
- removed png_large_malloc, png_large_free, and png_realloc functions.
-
-version 0.95 [March, 1997]
- fixed bug in pngwutil.c allocating "up_row" twice and "avg_row" never
- fixed bug in PNG file signature compares when start != 0
- changed parameter type of png_set_filler(...filler...) from png_byte
- to png_uint_32
- added test for MACOS to ensure that both math.h and fp.h are not #included
- added macros for libpng to be compiled as a Windows DLL (Andreas Kupries)
- added "packswap" transformation, which changes the endianness of
- packed-pixel bytes (Kevin Bracey)
- added "strip_alpha" transformation, which removes the alpha channel of
- input images without using it (not necessarily a good idea)
- added "swap_alpha" transformation, which puts the alpha channel in front
- of the color bytes instead of after
- removed all implicit variable tests which assume NULL == 0 (I think)
- changed several variables to "png_size_t" to show 16/32-bit limitations
- added new pCAL chunk read/write support
- added experimental filter selection weighting (Greg Roelofs)
- removed old png_set_rgbx() and png_set_xrgb() functions that have been
- obsolete for about 2 years now (use png_set_filler() instead)
- added macros to read 16- and 32-bit ints directly from buffer, to be
- used only on those systems that support it (namely PowerPC and 680x0)
- With some testing, this may become the default for MACOS/PPC systems.
- only calculate CRC on data if we are going to use it
- added macros for zTXt compression type PNG_zTXt_COMPRESSION_???
- added macros for simple libpng debugging output selectable at compile time
- removed PNG_READ_END_MODE in progressive reader (Smarasderagd)
- more description of info_struct in libpng.txt and png.h
- more instructions in example.c
- more chunk types tested in pngtest.c
- renamed pngrcb.c to pngset.c, and all png_read_<chunk> functions to be
- png_set_<chunk>. We now have corresponding png_get_<chunk>
- functions in pngget.c to get information in info_ptr. This isolates
- the application from the internal organization of png_info_struct
- (good for shared library implementations).
-
-version 0.96 [May, 1997]
- fixed serious bug with < 8bpp images introduced in 0.95
- fixed 256-color transparency bug (Greg Roelofs)
- fixed up documentation (Greg Roelofs, Laszlo Nyul)
- fixed "error" in pngconf.h for Linux setjmp() behaviour
- fixed DOS medium model support (Tim Wegner)
- fixed png_check_keyword() for case with error in static string text
- added read of CRC after IEND chunk for embedded PNGs (Laszlo Nyul)
- added typecasts to quiet compiler errors
- added more debugging info
-
-version 0.97 [January, 1998]
- removed PNG_USE_OWN_CRC capability
- relocated png_set_crc_action from pngrutil.c to pngrtran.c
- fixed typecasts of "new_key", etc. (Andreas Dilger)
- added RFC 1152 [sic] date support
- fixed bug in gamma handling of 4-bit grayscale
- added 2-bit grayscale gamma handling (Glenn R-P)
- added more typecasts. 65536L becomes (png_uint_32)65536L, etc. (Glenn R-P)
- minor corrections in libpng.txt
- added simple sRGB support (Glenn R-P)
- easier conditional compiling, e.g. define PNG_READ/WRITE_NOT_FULLY_SUPPORTED;
- all configurable options can be selected from command-line instead
- of having to edit pngconf.h (Glenn R-P)
- fixed memory leak in pngwrite.c (free info_ptr->text) (Glenn R-P)
- added more conditions for png_do_background, to avoid changing
- black pixels to background when a background is supplied and
- no pixels are transparent
- repaired PNG_NO_STDIO behaviour
- tested NODIV support and made it default behaviour (Greg Roelofs)
- added "-m" option and PNGTEST_DEBUG_MEMORY to pngtest (John Bowler)
- regularized version numbering scheme and bumped shared-library major
- version number to 2 to avoid problems with libpng 0.89 apps (Greg Roelofs)
-

- in example.c and libpng.txt, added comments to distinguish between
- screen_gamma, viewing_gamma, and display_gamma.
- changed all references to RFC1152 to read RFC1123 and changed the
- PNG_TIME_RFC1152_SUPPORTED macro to PNG_TIME_RFC1123_SUPPORTED
- added png_invert_alpha capability (Glenn R-P -- suggestion by Jon Vincent)
- changed srgb_intent from png_byte to int to avoid compiler bugs
-
-version 0.99 [January 30, 1998]
- free info_ptr->text instead of end_info_ptr->text in pngread.c (John Bowler)
- fixed a longstanding "packswap" bug in pngtrans.c
- fixed some inconsistencies in pngconf.h that prevented compiling with
- PNG_READ_GAMMA_SUPPORTED and PNG_READ_hIST_SUPPORTED undefined
- fixed some typos and made other minor rearrangement of libpng.txt (Andreas)
- changed recommendation about file_gamma for PC images to .50 from .51 in
- example.c and libpng.txt, and changed file_gamma for sRGB images to .45
- added a number of functions to access information from the png structure
- png_get_image_height(), etc. (Glenn R-P, suggestion by Brad Pettit)

- Renamed "far_to_near()" "png_far_to_near()"
- Revised libpng.3
- Version 99c "buffered" operations didn't work as intended. Replaced them

- write tEXt or zTXt chunks. If you want your application to be able to
- run with older versions of libpng, use
-
- #ifdef PNG_iTXt_SUPPORTED
- png_text[i].lang = NULL;
- #endif
-
- Changed png_get_oFFs() and png_set_oFFs() to use signed rather than unsigned

- Added members "lang_key" and "itxt_length" to png_text struct. Set
- text_length=0 when "text" contains iTXt data. Use the "compression"
- member to distinguish among tEXt/zTXt/iTXt types. Added
- PNG_ITXT_COMPRESSION_NONE (1) and PNG_ITXT_COMPRESSION_zTXt(2) macros.
- The "Note" above, about backward incompatibility of libpng-1.0.5e, no
- longer applies.

- (new in version 1.0.2), rgb_to_gray (new in 1.0.5), iCCP, sCAL, sPLT,
- the high-level interface, and unknown chunks support (all new in 1.0.6).
- This was necessary because of old applications that allocate the structs
- directly as authors were instructed to do in libpng-0.88 and earlier,
- instead of using png_create_*().
- Added modes PNG_CREATED_READ_STRUCT and PNG_CREATED_WRITE_STRUCT which
- can be used to detect codes that directly allocate the structs, and
- code to check these modes in png_read_init() and png_write_init() and
- generate a libpng error if the modes aren't set and PNG_LEGACY_SUPPORTED
- was not defined.

- overrun when old applications fill the info_ptr->text structure directly.

- Relocated version macro definitions ahead of the includes of zlib.h and
- pngconf.h in png.h.

-Installing libpng version 1.2.16 - January 31, 2007
-
-On Unix/Linux and similar systems, you can simply type
-
- ./configure [--prefix=/path]
- make check
- make install
-
-and ignore the rest of this document.
-
-If configure does not work on your system and you have a reasonably
-up-to-date set of tools, running ./autogen.sh before running ./configure
-may fix the problem. You can also run the individual commands in
-autogen.sh with the --force option, if supported by your version of
-the tools. If you run 'libtoolize --force', though, this will replace
-the distributed, patched, version of ltmain.sh with an unpatched version
-and your shared library builds may fail to produce libraries with the
-correct version numbers.
-
-Instead, you can use one of the custom-built makefiles in the
-"scripts" directory
-
- cp scripts/makefile.system makefile
- make test
- make install
-
-Or you can use one of the "projects" in the "projects" directory.
-
-If you want to use "cmake" (see www.cmake.org), copy CMakeLists.txt
-from the "scripts" directory to this directory and type
-
- cmake . [-DPNG_MMX=YES] -DCMAKE_INSTALL_PREFIX=/path
- make
- make install
-
-Before installing libpng, you must first install zlib, if it
-is not already on your system. zlib can usually be found
-wherever you got libpng. zlib can be placed in another directory,
-at the same level as libpng.
-
-If your system already has a preinstalled zlib you will still need
-to have access to the zlib.h and zconf.h include files that
-correspond to the version of zlib that's installed.
-
-You can rename the directories that you downloaded (they
-might be called "libpng-1.2.16" or "lpng109" and "zlib-1.2.1"
-or "zlib121") so that you have directories called "zlib" and "libpng".
-
-Your directory structure should look like this:
-
- .. (the parent directory)
- libpng (this directory)
- INSTALL (this file)
- README
- *.h
- *.c
- contrib
- gregbook
- pngminus
- pngsuite
- visupng
- projects
- beos
- c5builder (Borland)
- visualc6 (msvc)
- netware.txt
- wince.txt
- scripts
- makefile.*
- pngtest.png
- etc.
- zlib
- README
- *.h
- *.c
- contrib
- etc.
-
-If the line endings in the files look funny, you may wish to get the other
-distribution of libpng. It is available in both tar.gz (UNIX style line
-endings) and zip (DOS style line endings) formats.
-
-If you are building libpng with MSVC, you can enter the
-libpng projects\visualc6 directory and follow the instructions in
-projects\visualc6\README.txt.
-
-You can build libpng for WindowsCE by downloading and installing
-the projects\wince directory as instructed in the projects\wince.txt file, and
-then following the instructions in the README* files. Similarly, you can
-build libpng for Netware or Beos as instructed in projects\netware.txt
-or projects\beos.
-
-Else enter the zlib directory and follow the instructions in zlib/README,
-then come back here and run "configure" or choose the appropriate
-makefile.sys in the scripts directory.
