| Changes since the last public release (1.0.26): |
| |
| version 1.0.27 [August 18, 2007] |
| |
| Changed "const static" to "static PNG_CONST" everywhere, mostly undoing |
| change of libpng-1.2.17beta2. Changed other "const" to "PNG_CONST" |
| Fixed png_do_expand() to only use the appropriate bits of tRNS value. |
| Fixed png_handle_tRNS() to only use the appropriate bits of tRNS value. |
| Add some "png_byte" typecasts in png_check_keyword(). |
| Write new_key instead of key in zTXt chunk. |
| Add png_snprintf() function and use it in place of sprint() for improved |
| defense against buffer overflows. |
| Changed handling of some unused parameters, to avoid compiler warnings. |
| Removed some PNG_CONST in pngwutil.c to avoid compiler warnings. |
| Added some #ifdef PNG_MMX_CODE_SUPPORTED where needed in pngvcrd.c |
| Squelched png_squelch_warnings() in pnggccrd.c; Use "__attribute__((used))" |
| instead. |
| Removed __MMX__ from test in pngconf.h. |
| Updated makefile.sgcc and makefile.solaris; added makefile.solaris-x86. |
| Return 0 from png_get_sPLT() and png_get_unknown_chunks() if png_ptr is NULL; |
| changed three remaining instances of png_strcpy() to png_strncpy() (David |
| Hill). |
| Make test for NULL row_buf at the beginning of png_do_read_transformations |
| unconditional. |
| Prefer PNG_USE_PNGVCRD when _MSC_VER is defined in pngconf.h |
| Revised pnggccrd.c. |
| Updated contrib/gregbook. |
| Changed '#include "pnggccrd.c"' to 'include "$srcdir/pnggccrd.c"' |
| in configure.ac |
| Revised many of the makefiles, to set -DPNG_NO_MMX_CODE where needed |
| and to not use -O3 unless -DPNG_NO_MMX_CODE is also set. |
| Copied optimized C code from pnggccrd.c to pngrutil.c, removed dependency |
| on pnggccrd.o from many makefiles. |
| Added sl and dylib to list of extensions be installed by Makefile.am |
| Fixed testing PNG_RGB_TO_GRAY_ERR & PNG_RGB_TO_GRAY_WARN in pngrtran.c |
| Revised pngvcrd.c. |
| Rebuilt Makefile.in and configure using libtool-1.5.24. |
| Added "test" target to Makefile.in and Makefile.am |
| Added info about pngrutil/pnggccrd/pngvcrd to png_get_header_version() |
| Added PNG_NO_WRITE_FILTER and PNG_NO_WARNING macros. |
| Added contrib/pngminim to demonstrate building minimal encoder and decoder |
| Changed "png_free(str)" to "png_free(png_ptr,str)" in pngrutil.c WinCE |
| code (Yves Piguet). This bug was introduced in libpng-1.2.14. |
| Updated scripts/CMakeLists.txt |
| Fixed incorrect stride and number of bytes copied (was 4 instead of |
| 6 bytes) in the cleanup loop of pnggccrd.c and pngvcrd.c for handling |
| the end of 48-bit interlaced rows (Glenn R-P). |
| Added png_warning() in pngrutil.c for short iCCP, iTXt, sPLT, or zTXT chunks. |
| Revised pngtest.c so warnings are displayed regardless of PNG_NO_STDIO. |
| Disable PNG_MMX_CODE_SUPPORTED when PNG_ASSEMBLER_CODE_SUPPORTED is off. |
| Added information about disabling the MMX code in libpng documentation. |
| Removed some "#if 0" blocks. |
| Made a global struct local in pngvcrd.c to make it thread safe. |
| Change default to PNG_NO_GLOBAL_ARRAYS for MSVC. |
| Revise handling of png_strtod in recent versions of WINCE |
| Issue a png_error() if application attempts to transform a row tht |
| has not been initialized. |
