Eliminated useless call to png_check_cHRM() from pngset.c Expanded TAB characters in pngrtran.c version 1.2.41beta02 [September 30, 2009] Revised png_check_IHDR(). version 1.2.41beta03 [October 1, 2009] Revised png_check_IHDR() again, to check info_ptr members instead of the contents of the returned parameters. version 1.2.41beta04 [October 7, 2009] Added "xcode" project similar one already in libpng-1.4.0beta (Alam Arias). Ported some cosmetic changes from libpng-1.4.0beta86. Eliminated a shadowed declaration of "pp" in png_handle_sPLT(). version 1.2.41beta05 [October 17, 2009] 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. Ported some cosmetic changes from libpng-1.4.0beta87, changing many "#if defined(x)" to "#ifdef x". version 1.2.41beta06 [October 18, 2009] Restored PNG_USE_LOCAL_ARRAYS code in pngread.c that was inadvertently deleted in libpng-1.2.41beta05. Converted all PNG_NO_* tests to PNG_*_SUPPORTED everywhere except pngconf.h as in libpng-1.4.0beta78 and later. version 1.2.41beta07 [October 21, 2009] Ported some cosmetic changes from libpng-1.4.0rc01, changing many "#if defined(x)" to "#ifdef x" in png.h and pngconf.h. version 1.2.41beta08 [October 30, 2009] Ported from libpng-1.4.0rc01: png_calloc(), png_get_io_chunk_name(), png_get_io_state(), png_set_user_cache_max(), png_get_user_cache_max(), png_set_premultiply_alpha, and png_do_read_premultiply_alpha(). Relocated png_do_chop() ahead of building gamma tables in pngrtran.c 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. 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.
