| 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 | |

| 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) | |

| changed recommendation about file_gamma for PC images to .51 from .45, | |
| 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 | |

| added warnings when people try to set png_read_fn and png_write_fn in | |
| the same structure. | |
| Added a test such that png_do_gamma will be done when num_trans==0 | |
| for truecolor images that have defined a background. This corrects an | |
| error that was introduced in libpng-0.90 that can cause gamma processing | |
| to be skipped. | |

| Changed "static pngcharp tIME_string" to "static char tIME_string[30]" | |
| in pngtest.c (Duncan Simpson). | |
| Fixed a bug in pngtest.c that caused pngtest to try to write a tIME chunk | |
| even when no tIME chunk was present in the source file. | |
| Fixed a problem in pngrutil.c: gray_to_rgb didn't always work with 16-bit. | |

| Correct gamma with srgb is 45455 instead of 45000 in pngrutil.c, to be | |
| consistent with PNG-1.2, and allow variance of 500 before complaining. | |
| Added assembler code contributed by Intel in file pngvcrd.c and modified | |
| makefile.w32 to use it (Nirav Chhatrapati, INTEL Corporation, Gilles Vollant) | |
| Changed "ln -s -f" to "ln -f -s" in the makefiles to make Solaris happy. | |
| Added some aliases for png_set_expand() in pngrtran.c, namely | |
| png_set_expand_PLTE(), png_set_expand_depth(), and png_set_expand_tRNS() | |
| (Greg Roelofs, in "PNG: The Definitive Guide"). | |
| Added makefile.beo for BEOS on X86, contributed by Sander Stok. | |

| Define PNG_USE_PNGVCRD in makefile.w32, to get MMX assembler code. | |
| Made alternate versions of png_set_expand() in pngrtran.c, namely | |
| png_set_gray_1_2_4_to_8, png_set_palette_to_rgb, and png_set_tRNS_to_alpha | |
| (Greg Roelofs, in "PNG: The Definitive Guide"). Deleted the 1.0.3a aliases. | |
| Relocated start of 'extern "C"' block in png.h so it doesn't include pngconf.h | |
| Revised calculation of num_blocks in pngmem.c to avoid a potentially | |
| negative shift distance, whose results are undefined in the C language. | |
| Added a check in pngset.c to prevent writing multiple tIME chunks. | |
| Added a check in pngwrite.c to detect invalid small window_bits sizes. | |

| version 1.0.4c [October 1, 1999] | |
| Added a "png_check_version" function in png.c and pngtest.c that will generate | |
| a helpful compiler error if an old png.h is found in the search path. | |
| Changed type of png_user_transform_depth|channels from int to png_byte. | |

| Changed png_get_header_version() from a function to a macro in png.h | |
| Added type casting mostly in pngrtran.c and pngwtran.c | |
| Removed some pointless "ptr = NULL" in pngmem.c | |

| Fixed a typo in the png_set_sRGB() function call in example.c (Jan Nijtmans) | |
| Further optimization and bugfix of pngvcrd.c | |
| Revised pngset.c so that it does not allocate or free memory in the user's | |
| text_ptr structure. Instead, it makes its own copy. | |
| Created separate write_end_info_struct in pngtest.c for a more severe test. | |
| Added code in pngwrite.c to free info_ptr->text[i].key to stop a memory leak. | |
| version 1.0.5b [November 23, 1999] | |
| Moved PNG_FLAG_HAVE_CHUNK_HEADER, PNG_FLAG_BACKGROUND_IS_GRAY and | |
| PNG_FLAG_WROTE_tIME from flags to mode. | |
| Added png_write_info_before_PLTE() function. | |
| Fixed some typecasting in contrib/gregbook/*.c | |

| Moved png_get_header_version from png.h to png.c, to accommodate ansi2knr. | |
| Removed all global arrays (according to PNG_NO_GLOBAL_ARRAYS macro), to | |
| accommodate making DLL's: Moved usr_png_ver from global variable to function | |
| png_get_header_ver() in png.c. Moved png_sig to png_sig_bytes in png.c and | |
| eliminated use of png_sig in pngwutil.c. Moved the various png_CHNK arrays | |
| into pngtypes.h. Eliminated use of global png_pass arrays. Declared the | |
| png_CHNK and png_pass arrays to be "const". Made the global arrays | |
| available to applications (although none are used in libpng itself) when | |
| PNG_NO_GLOBAL_ARRAYS is not defined or when PNG_GLOBAL_ARRAYS is defined. | |
| Removed some extraneous "-I" from contrib/pngminus/makefile.std | |
| Changed the PNG_sRGB_INTENT macros in png.h to be consistent with PNG-1.2. | |
| Change PNG_SRGB_INTENT to PNG_sRGB_INTENT in libpng.txt and libpng.3 | |
| version 1.0.5d [November 29, 1999] | |
| Add type cast (png_const_charp) two places in png.c | |
| Eliminated pngtypes.h; use macros instead to declare PNG_CHNK arrays. | |
| Renamed "PNG_GLOBAL_ARRAYS" to "PNG_USE_GLOBAL_ARRAYS" and made available | |
| to applications a macro "PNG_USE_LOCAL_ARRAYS". | |
| Remove all the new declarations with #ifdef/#endif when | |
| PNG_USE_GLOBAL_ARRAYS is defined. | |
| Added PNG_EXPORT_VAR macro to accommodate making DLL's. | |
| version 1.0.5e [November 30, 1999] | |
| Added iCCP, iTXt, and sPLT support; added "lang" member to the png_text | |
| structure; refactored the inflate/deflate support to make adding new chunks | |
| with trailing compressed parts easier in the future, and added new functions | |
| png_free_iCCP, png_free_pCAL, png_free_sPLT, png_free_text, png_get_iCCP, | |
| png_get_spalettes, png_set_iCCP, png_set_spalettes (Eric S. Raymond). | |
| NOTE: Applications that write text chunks MUST define png_text->lang | |
| before calling png_set_text(). It must be set to NULL if you want to | |
| 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 | |
| offsets (Eric S. Raymond). | |
| Combined PNG_READ_cHNK_SUPPORTED and PNG_WRITE_cHNK_SUPPORTED macros into | |
| PNG_cHNK_SUPPORTED and combined the three types of PNG_text_SUPPORTED | |
| macros, leaving the separate macros also available. | |
| Removed comments on #endifs at the end of many short, non-nested #if-blocks. | |
| version 1.0.5f [December 6, 1999] | |
| Changed makefile.solaris to issue a warning about potential problems when | |
| the ucb "ld" is in the path ahead of the ccs "ld". | |
| Removed "- [date]" from the "synopsis" line in libpng.3 and libpngpf.3. | |
| Added sCAL chunk support (Eric S. Raymond). | |
| version 1.0.5g [December 7, 1999] | |
| Fixed "png_free_spallettes" typo in png.h | |
| Added code to handle new chunks in pngpread.c | |
| Moved PNG_CHNK string macro definitions outside of PNG_NO_EXTERN block | |
| Added "translated_key" to png_text structure and png_write_iTXt(). | |
| Added code in pngwrite.c to work around a newly discovered zlib bug. | |
| version 1.0.5h [December 10, 1999] | |
| NOTE: regarding the note for version 1.0.5e, the following must also | |
| be included in your code: | |
| png_text[i].translated_key = NULL; | |
| Unknown chunk handling is now supported. | |
| Option to eliminate all floating point support was added. Some new | |
| fixed-point functions such as png_set_gAMA_fixed() were added. | |
| Expanded tabs and removed trailing blanks in source files. | |
| version 1.0.5i [December 13, 1999] | |
| Added some type casts to silence compiler warnings. | |
| Renamed "png_free_spalette" to "png_free_spalettes" for consistency. | |
| Removed leading blanks from a #define in pngvcrd.c | |
| Added some parameters to the new png_set_keep_unknown_chunks() function. | |
| Added a test for up->location != 0 in the first instance of writing | |
| unknown chunks in pngwrite.c | |
| Changed "num" to "i" in png_free_spalettes() and png_free_unknowns() to | |
| prevent recursion. | |
| Added png_free_hIST() function. | |
| Various patches to fix bugs in the sCAL and integer cHRM processing, | |
| and to add some convenience macros for use with sCAL. | |
| version 1.0.5j [December 21, 1999] | |
| Changed "unit" parameter of png_write_sCAL from png_byte to int, to work | |
| around buggy compilers. | |
| Added new type "png_fixed_point" for integers that hold float*100000 values | |
| Restored backward compatibility of tEXt/zTXt chunk processing: | |
| Restored the first four members of png_text to the same order as v.1.0.5d. | |
| 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. | |
| Fixed png_read|write_iTXt() to read|write parameters in the right order, | |
| and to write the iTXt chunk after IDAT if it appears in the end_ptr. | |
| Added pnggccrd.c, version of pngvcrd.c Intel assembler for gcc (Greg Roelofs) | |
| Reversed the order of trying to write floating-point and fixed-point gAMA. | |
| version 1.0.5k [December 27, 1999] | |
| Added many parentheses, e.g., "if (a && b & c)" becomes "if (a && (b & c))" | |
| Added png_handle_as_unknown() function (Glenn) | |
| Added png_free_chunk_list() function and chunk_list and num_chunk_list members | |
| of png_ptr. | |
| Eliminated erroneous warnings about multiple sPLT chunks and sPLT-after-PLTE. | |
| Fixed a libpng-1.0.5h bug in pngrutil.c that was issuing erroneous warnings | |
| about ignoring incorrect gAMA with sRGB (gAMA was in fact not ignored) | |
| Added png_free_tRNS(); png_set_tRNS() now malloc's its own trans array (ESR). | |
| Define png_get_int_32 when oFFs chunk is supported as well as when pCAL is. | |
| Changed type of proflen from png_int_32 to png_uint_32 in png_get_iCCP(). | |
| version 1.0.5l [January 1, 2000] | |
| Added functions png_set_read_user_chunk_fn() and png_get_user_chunk_ptr() | |
| for setting a callback function to handle unknown chunks and for | |
| retrieving the associated user pointer (Glenn). | |
| version 1.0.5m [January 7, 2000] | |
| Added high-level functions png_read_png(), png_write_png(), png_free_pixels(). | |
| version 1.0.5n [January 9, 2000] | |
| Added png_free_PLTE() function, and modified png_set_PLTE() to malloc its | |
| own memory for info_ptr->palette. This makes it safe for the calling | |
| application to free its copy of the palette any time after it calls | |
| png_set_PLTE(). | |
| version 1.0.5o [January 20, 2000] | |
| Cosmetic changes only (removed some trailing blanks and TABs) | |
| version 1.0.5p [January 31, 2000] | |

| Revised makefile.gcmmx | |
| Added PNG_SETJMP_SUPPORTED, PNG_SETJMP_NOT_SUPPORTED, and PNG_ABORT() macros | |
| version 1.0.5r [February 7, 2000] | |
| Removed superfluous prototype for png_get_itxt from png.h | |
| Fixed a bug in pngrtran.c that improperly expanded the background color. | |
| Return *num_text=0 from png_get_text() when appropriate, and fix documentation | |
| of png_get_text() in libpng.txt/libpng.3. | |
| version 1.0.5s [February 18, 2000] | |
| Added "png_jmp_env()" macro to pngconf.h, to help people migrate to the | |
| new error handler that's planned for the next libpng release, and changed | |
| example.c, pngtest.c, and contrib programs to use this macro. | |
| Revised some of the DLL-export macros in pngconf.h (Greg Roelofs) | |
| Fixed a bug in png_read_png() that caused it to fail to expand some images | |
| that it should have expanded. | |
| Fixed some mistakes in the unused and undocumented INCH_CONVERSIONS functions | |
| in pngget.c | |
| Changed the allocation of palette, history, and trans arrays back to | |
| the version 1.0.5 method (linking instead of copying) which restores | |
| backward compatibility with version 1.0.5. Added some remarks about | |
| that in example.c. Added "free_me" member to info_ptr and png_ptr | |
| and added png_free_data() function. | |
| Updated makefile.linux and makefile.gccmmx to make directories conditionally. | |
| Made cosmetic changes to pngasmrd.h | |
| Added png_set_rows() and png_get_rows(), for use with png_read|write_png(). | |
| Modified png_read_png() to allocate info_ptr->row_pointers only if it | |
| hasn't already been allocated. | |
| version 1.0.5t [March 4, 2000] | |
| Changed png_jmp_env() migration aiding macro to png_jmpbuf(). | |
| Fixed "interlace" typo (should be "interlaced") in contrib/gregbook/read2-x.c | |
| Fixed bug with use of PNG_BEFORE_IHDR bit in png_ptr->mode, introduced when | |
| PNG_FLAG_HAVE_CHUNK_HEADER was moved into png_ptr->mode in version 1.0.5b | |
| Files in contrib/gregbook were revised to use png_jmpbuf() and to select | |
| a 24-bit visual if one is available, and to allow abbreviated options. | |
| Files in contrib/pngminus were revised to use the png_jmpbuf() macro. | |
| Removed spaces in makefile.linux and makefile.gcmmx, introduced in 1.0.5s | |
| version 1.0.5u [March 5, 2000] | |
| Simplified the code that detects old png.h in png.c and pngtest.c | |
| Renamed png_spalette (_p, _pp) to png_sPLT_t (_tp, _tpp) | |
| Increased precision of rgb_to_gray calculations from 8 to 15 bits and | |
| added png_set_rgb_to_gray_fixed() function. | |
| Added makefile.bc32 (32-bit Borland C++, C mode) | |
| version 1.0.5v [March 11, 2000] | |
| Added some parentheses to the png_jmpbuf macro definition. | |
| Updated references to the zlib home page, which has moved to freesoftware.com. | |
| Corrected bugs in documentation regarding png_read_row() and png_write_row(). | |
| Updated documentation of png_rgb_to_gray calculations in libpng.3/libpng.txt. | |
| Renamed makefile.borland,turboc3 back to makefile.bor,tc3 as in version 1.0.3, | |
| revised borland makefiles; added makefile.ibmvac3 and makefile.gcc (Cosmin) | |
| version 1.0.6 [March 20, 2000] | |
| Minor revisions of makefile.bor, libpng.txt, and gregbook/rpng2-win.c | |
| Added makefile.sggcc (SGI IRIX with gcc) | |
| version 1.0.6d [April 7, 2000] | |
| Changed sprintf() to strcpy() in png_write_sCAL_s() to work without STDIO | |
| Added data_length parameter to png_decompress_chunk() function | |
| Revised documentation to remove reference to abandoned png_free_chnk functions | |
| Fixed an error in png_rgb_to_gray_fixed() | |
| Revised example.c, usage of png_destroy_write_struct(). | |
| Renamed makefile.ibmvac3 to makefile.ibmc, added libpng.icc IBM project file | |
| Added a check for info_ptr->free_me&PNG_FREE_TEXT when freeing text in png.c | |
| Simplify png_sig_bytes() function to remove use of non-ISO-C strdup(). | |
| version 1.0.6e [April 9, 2000] | |
| Added png_data_freer() function. | |
| In the code that checks for over-length tRNS chunks, added check of | |
| info_ptr->num_trans as well as png_ptr->num_trans (Matthias Benckmann) | |
| Minor revisions of libpng.txt/libpng.3. | |
| Check for existing data and free it if the free_me flag is set, in png_set_*() | |
| and png_handle_*(). | |
| Only define PNG_WEIGHTED_FILTERS_SUPPORTED when PNG_FLOATING_POINT_SUPPORTED | |
| is defined. | |
| Changed several instances of PNG_NO_CONSOLE_ID to PNG_NO_STDIO in pngrutil.c | |
| and mentioned the purposes of the two macros in libpng.txt/libpng.3. | |
| version 1.0.6f [April 14, 2000] | |
| Revised png_set_iCCP() and png_set_rows() to avoid prematurely freeing data. | |
| Add checks in png_set_text() for NULL members of the input text structure. | |
| Revised libpng.txt/libpng.3. | |
| Removed superfluous prototype for png_set_itxt from png.h | |
| Removed "else" from pngread.c, after png_error(), and changed "0" to "length". | |
| Changed several png_errors about malformed ancillary chunks to png_warnings. | |
| version 1.0.6g [April 24, 2000] | |
| Added png_pass-* arrays to pnggccrd.c when PNG_USE_LOCAL_ARRAYS is defined. | |
| Relocated paragraph about png_set_background() in libpng.3/libpng.txt | |
| and other revisions (Matthias Benckmann) | |
| Relocated info_ptr->free_me, png_ptr->free_me, and other info_ptr and | |
| png_ptr members to restore binary compatibility with libpng-1.0.5 | |
| (breaks compatibility with libpng-1.0.6). | |
| version 1.0.6h [April 24, 2000] | |
| Changed shared library so-number pattern from 2.x.y.z to xy.z (this builds | |
| libpng.so.10 & libpng.so.10.6h instead of libpng.so.2 & libpng.so.2.1.0.6h) | |
| This is a temporary change for test purposes. | |
| version 1.0.6i [May 2, 2000] | |
| Rearranged some members at the end of png_info and png_struct, to put | |
| unknown_chunks_num and free_me within the original size of the png_structs | |
| and free_me, png_read_user_fn, and png_free_fn within the original png_info, | |
| because some old applications allocate the structs directly instead of | |
| using png_create_*(). | |
| Added documentation of user memory functions in libpng.txt/libpng.3 | |
| Modified png_read_png so that it will use user_allocated row_pointers | |
| if present, unless free_me directs that it be freed, and added description | |
| of the use of png_set_rows() and png_get_rows() in libpng.txt/libpng.3. | |
| Added PNG_LEGACY_SUPPORTED macro, and #ifdef out all new (since version | |
| 1.00) members of png_struct and png_info, to regain binary compatibility | |
| when you define this macro. Capabilities lost in this event | |
| are user transforms (new in version 1.0.0),the user transform pointer | |
| (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. | |
| Added makefile.intel and updated makefile.watcom (Pawel Mrochen) | |
| version 1.0.6j [May 3, 2000] | |
| Overloaded png_read_init() and png_write_init() with macros that convert | |
| calls to png_read_init_2() or png_write_init_2() that check the version | |
| and structure sizes. | |
| version 1.0.7beta11 [May 7, 2000] | |
| Removed the new PNG_CREATED_READ_STRUCT and PNG_CREATED_WRITE_STRUCT modes | |
| which are no longer used. | |
| Eliminated the three new members of png_text when PNG_LEGACY_SUPPORTED is | |
| defined or when neither PNG_READ_iTXt_SUPPORTED nor PNG_WRITE_iTXT_SUPPORTED | |
| is defined. | |
| Made PNG_NO_READ|WRITE_iTXt the default setting, to avoid memory | |
| overrun when old applications fill the info_ptr->text structure directly. | |
| Added PNGAPI macro, and added it to the definitions of all exported functions. | |
| Relocated version macro definitions ahead of the includes of zlib.h and | |
| pngconf.h in png.h. | |
| version 1.0.7beta12 [May 12, 2000] | |
| Revised pngset.c to avoid a problem with expanding the png_debug macro. | |
| Deleted some extraneous defines from pngconf.h | |
| Made PNG_NO_CONSOLE_IO the default condition when PNG_BUILD_DLL is defined. | |
| Use MSC _RPTn debugging instead of fprintf if _MSC_VER is defined. | |
| Added png_access_version_number() function. | |
| Check for mask&PNG_FREE_CHNK (for TEXT, SCAL, PCAL) in png_free_data(). | |
| Expanded libpng.3/libpng.txt information about png_data_freer(). | |
| version 1.0.7beta14 [May 17, 2000] (beta13 was not published) | |
| Changed pnggccrd.c and pngvcrd.c to handle bad adaptive filter types as | |
| warnings instead of errors, as pngrutil.c does. | |
| Set the PNG_INFO_IDAT valid flag in png_set_rows() so png_write_png() | |
| will actually write IDATs. | |
| Made the default PNG_USE_LOCAL_ARRAYS depend on PNG_DLL instead of WIN32. | |
| Make png_free_data() ignore its final parameter except when freeing data | |
| that can have multiple instances (text, sPLT, unknowns). | |
| Fixed a new bug in png_set_rows(). | |
| Removed info_ptr->valid tests from png_free_data(), as in version 1.0.5. | |
| Added png_set_invalid() function. | |
| Fixed incorrect illustrations of png_destroy_write_struct() in example.c. | |
| version 1.0.7beta15 [May 30, 2000] | |
| Revised the deliberately erroneous Linux setjmp code in pngconf.h to produce | |
| fewer error messages. | |
| Rearranged checks for Z_OK to check the most likely path first in pngpread.c | |
| and pngwutil.c. | |
| Added checks in pngtest.c for png_create_*() returning NULL, and mentioned | |
| in libpng.txt/libpng.3 the need for applications to check this. | |
| Changed names of png_default_*() functions in pngtest to pngtest_*(). | |
| Changed return type of png_get_x|y_offset_*() from png_uint_32 to png_int_32. | |
| Fixed some bugs in the unused PNG_INCH_CONVERSIONS functions in pngget.c | |
| Set each pointer to NULL after freeing it in png_free_data(). | |
| Worked around a problem in pngconf.h; AIX's strings.h defines an "index" | |
| macro that conflicts with libpng's png_color_16.index. (Dimitri Papadapoulos) | |

| Use png_memset() after png_malloc() of big_row_buf when reading an | |
| interlaced file, to avoid a possible UMR. | |
| Undid recent revision of PNG_NO_STDIO version of png_write_flush(). Users | |

| Added "#define PNG_NO_WRITE_FLUSH" to contrib/pngminim/encoder/pngusr.h | |
| version 1.2.36beta03 [March 27, 2009] | |

| No changes. | |
| version 1.2.37beta01 [May 14, 2009] | |
| Fixed inconsistency in pngrutil.c, introduced in libpng-1.2.36. The | |
| memset() was using "png_ptr->rowbytes" instead of "row_bytes", which | |

| version 1.2.37beta03 [May 20, 2009] | |
| In contrib/pngminim/*, renamed "makefile.std" to "makefile", since there | |
| is only one makefile in those directories, and revised the README files | |
| accordingly. | |
| Reformated sources in libpng style (3-space indentation, comment format) | |
| version 1.2.37rc01 [May 27, 2009] | |
| No changes. | |

| Revised libpng*.txt and libpng.3 to mention calling png_set_IHDR() | |
| multiple times and to specify the sample order in the tRNS chunk, | |
| because the ISO PNG specification has a typo in the tRNS table. | |
| Changed several PNG_UNKNOWN_CHUNK_SUPPORTED to | |
| PNG_HANDLE_AS_UNKNOWN_SUPPORTED, to make the png_set_keep mechanism | |
| available for ignoring known chunks even when not saving unknown chunks. | |
| Adopted preference for consistent use of "#ifdef" and "#ifndef" versus | |
| "#if defined()" and "if !defined()" where possible. | |
| Added PNG_NO_HANDLE_AS_UNKNOWN in the PNG_LEGACY_SUPPORTED block of | |
| pngconf.h, and moved the various unknown chunk macro definitions | |
| outside of the PNG_READ|WRITE_ANCILLARY_CHUNK_SUPPORTED blocks. | |

| Added "xcode" project similar one already in libpng-1.4.0beta (Alam Arias). | |
| Ported some cosmetic changes from libpng-1.4.0beta86. | |

| version 1.2.41beta05 [October 17, 2009] | |
| Revised pngconf.h to make it easier to enable iTXt support. From libpng | |

| This avoids building 16-bit gamma tables unnecessarily. | |
| version 1.2.41beta09 [November 1, 2009] | |
| Removed a harmless extra png_set_invert_alpha() from pngwrite.c | |
| More bugfixes and improvements to CMakeLists.txt (Philip Lowman) | |
| Moved CMakeLists.txt from scripts into the main libpng directory. | |
| Apply png_user_chunk_cache_max within png_decompress_chunk(). | |
| Merged libpng-1.2.41.txt with libpng-1.4.0.txt where appropriate. | |
| version 1.2.41beta10 [November 1, 2009] | |
| Enabled iTXt support by default. To ensure binary compatibility with | |
| previous versions, the "lang" and "lang_key" members will be assumed | |
| to be omitted from previous versions unless the current libpng | |
| version was built with PNG_iTXt_SUPPORTED (which is otherwise no | |
| longer necessary to gain iTXt support), as a signal that the user has | |
| been building previous versions with PNG_iTXt_SUPPORTED as well. | |
| version 1.2.41beta11 [November 2, 2009] | |
| Store user's user_png_ver in new png_ptr->user_png_ver element. | |
| Revised iTXt support. To ensure binary compatibility with | |
| previous versions, the "lang" and "lang_key" members will be assumed | |
| to be omitted from versions prior to 1.2.41beta11 whenever there is a | |
| library mismatch. | |
| version 1.2.41beta12 [November 2, 2009] | |
| Free png_ptr->user_png_ver when destroying png_ptr. | |
| version 1.2.41beta13 [November 3, 2009] | |
| Updated scripts/pngw32.def and projects/wince/png32ce.def | |
| Copied projects/wince/png32ce.def to the scripts directory. | |
| Added scripts/makefile.wce | |
| Patched ltmain.sh for wince support. | |
| Added PNG_CONVERT_tIME_SUPPORTED macro. | |
| version 1.2.41beta14 [November 8, 2009] | |
| versions 1.2.41beta05 through 1.2.41beta13 were abandoned. | |
| The 1.0.x/1.2.x series will only receive security updates from now on. | |
| Make inclusion of time.h in pngconf.h depend on PNG_CONVERT_tIME_SUPPORTED | |
| Make #define PNG_CONVERT_tIME_SUPPORTED depend on PNG_WRITE_tIME_SUPPORTED | |
| Reverted iTXt compatibility stuff from 1.2.41beta05, 1.2.41beta11, and | |
| 1.2.41beta12. | |
| Reverted IOSTATE feature, user_cache_max, and premultiply_alpha features | |
| from 1.2.41beta08. | |
| Retained png_calloc() from 1.2.41beta08 but as a non-exported function, | |
| and removed reference to png_calloc from scripts/*.def | |
| version 1.2.41beta15 [November 8, 2009] | |
| Added PNG_DEPSTRUCT, PNG_DEPRECATED, PNG_USE_RESULT, PNG_NORETURN, and | |
| PNG_ALLOCATED macros to detect deprecated direct access to the | |
| png_struct or info_struct members and other deprecated usage in | |
| applications (John Bowler). | |
| Updated scripts/makefile* to add "-DPNG_CONFIGURE_LIBPNG" to CFLAGS, | |
| to prevent warnings about direct access to png structs by libpng | |
| functions while building libpng. They need to be tested, especially | |
| those using compilers other than gcc. | |
| Updated projects/visualc6 and visualc71 with "/d PNG_CONFIGURE_LIBPNG". | |
| version 1.2.41beta16 [November 9, 2009] | |
| Removed three direct references to read_info_ptr members in pngtest.c | |
| that were detected by the new PNG_DEPSTRUCT macro. | |
| Only #define PNG_DEPSTRUCT, etc. in pngconf.h if not already defined. | |
| version 1.2.41beta17 [November 10, 2009] | |
| Updated CMakeLists.txt to add "-DPNG_CONFIGURE_LIBPNG" to the definitions. | |
| Marked deprecated function prototypes with PNG_DEPRECATED. | |
| Marked memory allocation function prototypes with PNG_ALLOCATED. | |
| Changed png_check_sig() to !png_sig_cmp() in contrib programs. | |
| Corrected the png_get_IHDR() call in contrib/gregbook/readpng2.c | |
| Added "-DPNG_CONFIGURE_LIBPNG" to the contrib/pngminum makefiles. | |
| version 1.2.41beta18 [November 11, 2009] | |
| Renamed scripts/makefile.wce to scripts/makefile.cegcc | |
| Marked nonexported functions with PNG_PRIVATE macro. | |
| version 1.2.41rc01 and 1.0.51rc01 [November 18, 2009] | |
| Revised scripts/*.def to reflect functions actually exported by libpng. | |
| Updated the copyright year in scripts/pngw32.rc from 2004 to 2009. | |
| Moved descriptions of makefiles and other scripts out of INSTALL into | |
| scripts/README.txt | |
| version 1.2.41rc02 [November 22, 2009] | |
| Rebuilt the configure scripts with autoconf-2.65 | |
| version 1.2.41rc03 [November 25, 2009] | |
| Disabled the new pedantic warnings about deprecated function use | |
| and deprecated structure access unless the user defines | |
| PNG_PEDANTIC_WARNINGS. | |
| Added "#define PNG_NO_PEDANTIC_WARNINGS" in the libpng source files. | |
| Removed "-DPNG_CONFIGURE_LIBPNG" from the makefiles and projects. | |
| version 1.2.41 and 1.0.51 [December 3, 2009] | |
| Updated the list of files and made some cosmetic changes in README. | |
| version 1.2.42beta01 [December 4, 2009] | |
| Removed "#define PNG_NO_ERROR_NUMBERS" that was inadvertently added | |
| to pngconf.h in version 1.2.41. | |
| Revised scripts/makefile.netbsd, makefile.openbsd, and makefile.sco | |
| to put png.h and pngconf.h in $prefix/include, like the other scripts, | |
| instead of in $prefix/include/libpng. Also revised makefile.sco | |
| to put them in $prefix/include/libpng12 instead of in | |
| $prefix/include/libpng/libpng12. | |
| Removed leftover "-DPNG_CONFIGURE_LIBPNG" from scripts/makefile.darwin | |
| version 1.2.42beta02 [December 11, 2009] | |
| Removed leftover "-DPNG_CONFIGURE_LIBPNG" from contrib/pngminim/*/makefile | |
| Relocated png_do_chop() to its original position in pngrtran.c. The | |
| change in version 1.2.41beta08 caused transparency to be handled wrong | |
| in some 16-bit datastreams (Yusaku Sugai). | |
| version 1.2.42rc01 [December 17, 2009] | |
| No changes. | |
| version 1.2.42rc02 [December 22, 2009] | |
| Renamed libpng-pc.in back to libpng.pc.in and revised CMakeLists.txt | |

| version 1.2.42rc03 [December 25, 2009] | |
| Swapped PNG_UNKNOWN_CHUNKS_SUPPORTED and PNG_HANDLE_AS_UNKNOWN_SUPPORTED | |
| in pngset.c to be consistent with other changes in version 1.2.38. | |
| version 1.2.42rc04 [January 1, 2010] | |

| No changes. | |
| version 1.2.43beta01 [January 27, 2010] | |
| Updated CMakeLists.txt for consistent indentation and to avoid an | |
| unclosed if-statement warning (Philip Lowman). | |
| Removed "#ifdef PNG_1_0_X / #endif" surrounding | |
| PNG_READ_16_TO_8_SUPPORTED and PNG_READ_GRAY_TO_RGB_SUPPORTED | |
| in pngconf.h. These were added in libpng-1.2.41beta08 and libpng-1.0.51, | |
| which introduced a binary incompatibility with libpng-1.0.50. | |

| Reverted recent changes to png_push_save-buffer(). | |
| Removed PNGAPI declaration of png_calloc() and png_write_sig() in | |
| 1ibpng-1.2.X, introduced by mistake in libpng-1.2.41. | |

| to avoid a potential memory leak. | |
| version 1.2.43beta05 [February 8, 2010] | |
| Ported rewritten png_decompress_chunk() by John Bowler from libpng-1.4.1. | |
| version 1.0.53rc01 and 1.2.43rc01 [February 18, 2010] | |
| No changes. | |
| version 1.0.53rc02 and 1.2.43rc02 [February 19, 2010] | |
| Define _ALL_SOURCE in configure.ac, makefile.aix, and CMakeLists.txt | |
| when using AIX compiler. | |
| version 1.0.53 and 1.2.43 [February 25, 2010] | |

| version 1.2.44beta03 [June 20, 2010] | |
| Rewrote png_process_IDAT_data() to consistently treat extra data as warnings | |
| and handle end conditions more cleanly. | |
| Removed the new (beta02) check in png_push_process_row(). | |
| version 1.2.44rc01 [June 21, 2010] | |
| Revised some comments in png_process_IDAT_data(). | |
| version 1.2.44rc02 [June 22, 2010] | |
| Stop memory leak when reading a malformed sCAL chunk. | |
| version 1.2.44rc03 [June 23, 2010] | |
| Revised pngpread.c patch of beta05 to avoid an endless loop. | |
