Changes since the last public release (1.5.9):
|
||
|
|
|
||
|
|
Removed two useless #ifdef directives from pngread.c and one from pngrutil.c
|
||
|
|
Always put the CMAKE_LIBRARY in "lib" (removed special WIN32 case).
|
||
|
|
Removed empty vstudio/pngstest directory (Clifford Yapp).
|
||
|
|
Eliminated redundant png_push_read_tEXt|zTXt|iTXt|unknown code from
|
||
|
|
pngpread.c and use the sequential png_handle_tEXt, etc., in pngrutil.c;
|
||
|
|
now that png_ptr->buffer is inaccessible to applications, the special
|
||
|
|
handling is no longer useful.
|
||
|
|
Fixed bug with png_handle_hIST with odd chunk length (Frank Busse).
|
||
|
|
Added PNG_SAFE_LIMITS feature to pnglibconf.dfa and code in pngconf.h
|
||
|
|
to reset the user limits to safe ones if PNG_SAFE_LIMITS is defined.
|
||
|
|
To enable, use "CPPFLAGS=-DPNG_SAFE_LIMITS_SUPPORTED" on the configure
|
||
|
|
command or put "#define PNG_SAFE_LIMITS_SUPPORTED" in pnglibconf.h.
|
||
|
|
Revised the SAFE_LIMITS feature to be the same as the feature in libpng16.
|
||
|
|
Added information about the new limits in the manual.
|
||
|
|
Updated Makefile.in
|
||
|
|
Removed unused "current_text" members of png_struct and the png_free()
|
||
|
|
of png_ptr->current_text from pngread.c
|
||
|
|
Fixed PNG_LIBPNG_BUILD_BASE_TYPE definition.
|
||
|
|
Fixed CMF optimization of non-IDAT compressed chunks, which was added at
|
||
|
|
libpng-1.5.4. It sometimes produced too small of a window.
|
||
|
|
Reject all iCCP chunks after the first, even if the first one is invalid.
|
||
|
|
Added palette-index checking. Issue a png_benign_error() if an invalid
|
||
|
|
index is found.
|
||
|
|
Revised example.c to put text strings in a temporary character array
|
||
|
|
instead of directly assigning string constants to png_textp members.
|
||
|
|
This avoids compiler warnings when -Wwrite-strings is enabled.
|
||
|
|
Prevent PNG_EXPAND+PNG_SHIFT doing the shift twice.
|
||
|
|
Revised png_set_text_2() to avoid potential memory corruption (fixes
|
||
|
|
CVE-2011-3048).
