| Libpng 1.0.5d - November 29, 1999 |
| |
| This is not intended to be a public release. It will be replaced |
| within a few weeks by a public version or by another test version. |
| |
| Changes since the last public release (1.0.5): |
| |
| version libpng-1.0.5a October 23, 1999 |
| Added contrib/pngsuite and contrib/pngminus (Willem van Schaik) |
| 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 libpng-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 |
| Updated scripts/makevms.com and added makevms.com to contrib/gregbook |
| and contrib/pngminus (Martin Zinser) |
| version libpng-1.0.5c November 26, 1999 |
| Moved png_get_header_version from png.h to png.c, to accomodate ansi2knr. |
| Removed all global arrays (according to PNG_NO_GLOBAL_ARRAYS macro), to |
| accomodate 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". |
| #ifdef out all the new declarations when PNG_USE_GLOBAL_ARRAYS is defined. |
| Added PNG_EXPORT_VAR macro to accommodate making DLL's. |
