Changes since the last public release (1.4.0beta107):
|
|
|
|
version 1.4.1alpha01 [November 27, 2009]
|
|
Based on 1.4.0beta107 (prerelease)
|
|
|
|
version 1.4.1alpha02 [December 11, 2009]
|
|
Restored premultiplied alpha feature from version 1.4.0beta105.
|
|
Added "double gamma" to parameters for png_set_premultiply_alpha().
|
|
Added "float postmultiply_gamma" member to the png_struct.
|
|
Moved PNG_DIVIDE_BY_255, PNG_8_BIT_PREMULTIPLY(), etc., from
|
|
png.h to pngpriv.h
|
|
Updated documentation about png_set_premultiply_alpha().
|
|
Always expand pixels to 16-bit samples when premultiplying.
|
|
In pngconf.h, require PNG_GAMMA_SUPPORTED to be defined when defining
|
|
PNG_READ_PREMULTIPLY_ALPHA_SUPPORTED
|
|
Eliminated PNG_DIVIDE_BY_255 and PNG_8_BIT_PREMULTIPLY macros
|
|
leaving only PNG_DIVIDE_BY_65535 and PNG_16_BIT_PREMULTIPLY
|
|
because we will always work with 16 bits.
|
|
Sync with version 1.4.0beta107:
|
|
Updated README
|
|
Added "#define PNG_NO_PEDANTIC_WARNINGS" in the libpng source files.
|
|
Removed "-DPNG_CONFIGURE_LIBPNG" from the makefiles, projects, and contrib.
|
|
Revised scripts/makefile.netbsd, makefile.openbsd, and makefile.sco
|
|
to put png.h and pngconf.h in $prefix/include, like the other scripts,
|
|
instead of in $prefix/include/libpng. Also revised makefile.sco
|
|
to put them in $prefix/include/libpng15 instead of in
|
|
$prefix/include/libpng/libpng15.
|
|
Relocated png_do_chop() to its original position in pngrtran.c; the
|
|
change in version 1.2.41beta08 caused transparency to be handled wrong
|
|
in some 16-bit datastreams (Yusaku Sugai).
|
|
|
|
version 1.5.0alpha01 [January 2, 2010]
|
|
Bump version to 1.5.0alpha01
|
|
Add "depth" parameter to private png_build_gamma_table()
|
|
Declared png_cleanup_needed "volatile" in pngread.c and pngwrite.c
|
|
Renamed libpng-pc.in back to libpng.pc.in and revised CMakeLists.txt
|
|
(revising the change in 1.4.0beta99)
|
|
Swapped PNG_UNKNOWN_CHUNKS_SUPPORTED and PNG_HANDLE_AS_UNKNOWN_SUPPORTED
|
|
in pngset.c to be consistent with other changes in version 1.2.38.
|
|
Changed "libpng-pc.in" to "libpng.pc.in" in configure.ac, configure, and
|
|
Makefile.in to be consistent with changes in libpng-1.4.0rc03
|
|
Avoid deprecated references to png_ptr-io_ptr and png_ptr->error_ptr
|
|
in pngtest.c
|
|
Recognize and use "--sysroot=DIR" in libpng-config.in and libpng.pc.in
|
|
Recognize and use environment variable $PKG_CONFIG_SYSROOT_DIR as default
|
|
setting of ${sysroot} in libpng.pc.in
