|
|
Changes since the last public release (1.5.10):
|
|
Revised scripts/makefile.darwin: use system zlib; remove quotes around
|
|
architecture list; add missing ppc architecture; add architecture options
|
|
to shared library link; don't try to create a shared lib based on missing
|
|
RELEASE variable.
|
|
Enable png_set_check_for_invalid_index() for both read and write.
|
|
Removed #ifdef PNG_HANDLE_AS_UNKNOWN_SUPPORTED/#endif in pngpriv.h around
|
|
declaration of png_handle_unknown().
|
|
Added -lssp_nonshared in a comment in scripts/makefile.freebsd
|
|
and changed deprecated NOOBJ and NOPROFILE to NO_OBJ and NO_PROFILE.
|
|
Revised CMakeLists.txt to not attempt to make a symlink under mingw.
|
|
Added two images to contrib/pngsuite (1-bit and 2-bit transparent grayscale),
|
|
and renamed three whose names were inconsistent with those in
|
|
pngsuite/README.txt.
|
|
Do not depend upon a GCC feature macro being available for use in generating
|
|
the linker mapfile symbol prefix.
|
|
Made fixes for new optimization warnings from gcc 4.7.0. The compiler
|
|
performed an optimization which is safe but then warned about it.
|
|
Changing the type of 'palette_number' in pngvalid.c removes the warning.
|
|
Improved efficiency of new do_check_palette_indexes() function.
|
|
Don't check palette indexes if num_palette is 0 (as it can be in MNG files).
|
|
Include zlib.h in contrib/gregbook and contrib/visupng examples.
