| Changes since the last public release (1.0.50): |
| |
| version 1.0.51 [December 3, 2009] |
| |
| Moved redundant IHDR checking into new png_check_IHDR() in png.c |
| and report all errors found in the IHDR data. |
| Eliminated useless call to png_check_cHRM() from pngset.c |
| Expanded TAB characters in pngrtran.c |
| Added "xcode" project similar one already in libpng-1.4.0beta (Alam Arias). |
| Eliminated a shadowed declaration of "pp" in png_handle_sPLT(). |
| Revised pngconf.h to make it easier to enable iTXt support. From libpng |
| version 1.2.9 through 1.2.40, defining PNG_iTXt_SUPPORTED did not work |
| as expected. |
| Converted all PNG_NO_* tests to PNG_*_SUPPORTED everywhere except pngconf.h |
| Changed many "#if defined(x)" to "#ifdef x" and fixed some indentation. |
| Added png_calloc() as a non-exported function. |
| Relocated png_do_chop() ahead of building gamma tables in pngrtran.c |
| This avoids building 16-bit gamma tables unnecessarily. |
| Removed a harmless extra png_set_invert_alpha() from pngwrite.c |
| Bugfixes and improvements to CMakeLists.txt (Philip Lowman) |
| Moved CMakeLists.txt from scripts into the main libpng directory. |
| Patched ltmain.sh for wince support. |
| Added PNG_CONVERT_tIME_SUPPORTED macro. |
| Make inclusion of time.h in pngconf.h depend on PNG_CONVERT_tIME_SUPPORTED |
| Updated scripts/pngw32.def and projects/wince/png32ce.def |
| Copied projects/wince/png32ce.def to the scripts directory. |
| Added scripts/makefile.cegcc |
| 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). |
| Removed three direct references to read_info_ptr members in pngtest.c |
| that were detected by the new PNG_DEPSTRUCT macro. |
| 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 |
| Marked nonexported functions with PNG_PRIVATE macro. |
| 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 |
| Rebuilt the configure scripts with autoconf-2.65 |
| 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. |
| Updated the list of files and made some cosmetic changes in README. |
