Libpng 1.2.1 - December 12, 2001
|
||
|
|
|
||
|
|
This is a public release of libpng, intended for use in production codes.
|
||
|
|
|
||
|
|
Changes since the last public release (1.2.0):
|
||
|
|
|
||
|
|
Revised makefile.std in contrib/pngminus
|
||
|
|
Include background_1 in png_struct regardless of gamma support.
|
||
|
|
Revised makefile.netbsd and makefile.macosx, added makefile.darwin.
|
||
|
|
Revised example.c to provide more details about using row_callback().
|
||
|
|
Added makefile.so9.
|
||
|
|
Removed type casts from all NULLs, except for those appearing in function
|
||
|
|
calls when PNG_NO_TYPECAST_NULL is defined.
|
||
|
|
Simplified png_create_info_struct() and png_creat_struct_2().
|
||
|
|
Added error message if png_write_info() was omitted.
|
||
|
|
Changed typecast of "size" argument to png_size_t in pngmem.c calls to
|
||
|
|
the user malloc_fn, to agree with the prototype in png.h
|
||
|
|
Added a pop/push operation to pnggccrd.c, to preserve Eflag (Maxim Sobolev)
|
||
|
|
Updated makefile.sgi to recognize LIBPATH and INCPATH.
|
||
|
|
Updated various makefiles so "make clean" does not remove previous major
|
||
|
|
version of the shared library.
|
||
|
|
Added a pop/push operation to pngvcrd.c, to preserve Eflag.
|
||
|
|
Always allocate 256-entry internal palette, hist, and trans arrays, to
|
||
|
|
avoid out-of-bounds memory reference caused by invalid PNG datastreams.
|
||
|
|
Added a check for prefix_length > data_length in iCCP chunk handler.
