Changes since the last public release (1.2.40): version 1.2.41 [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.
now in the tree; thanks
