|
|
|
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.
