|
|
Changes since the last public release (1.2.40):
|
|
|
|
version 1.2.41beta01 [September 25, 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
|
|
|
|
version 1.2.41beta02 [September 30, 2009]
|
|
Revised png_check_IHDR().
|
|
|
|
version 1.2.41beta03 [October 1, 2009]
|
|
Revised png_check_IHDR() again, to check info_ptr members instead of
|
|
the contents of the returned parameters.
|
|
|
|
version 1.2.41beta04 [October 7, 2009]
|
|
Added "xcode" project similar one already in libpng-1.4.0beta (Alam Arias).
|
|
Ported some cosmetic changes from libpng-1.4.0beta86.
|
|
Eliminated a shadowed declaration of "pp" in png_handle_sPLT().
|
|
|
|
version 1.2.41beta05 [October 17, 2009]
|
|
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.
|
|
Ported some cosmetic changes from libpng-1.4.0beta87, changing
|
|
many "#if defined(x)" to "#ifdef x".
|
|
|
|
version 1.2.41beta06 [October 18, 2009]
|
|
Restored PNG_USE_LOCAL_ARRAYS code in pngread.c that was inadvertently
|
|
deleted in libpng-1.2.41beta05.
|
|
Converted all PNG_NO_* tests to PNG_*_SUPPORTED everywhere except pngconf.h
|
|
as in libpng-1.4.0beta78 and later.
|
|
|
|
version 1.2.41beta07 [October 21, 2009]
|
|
Ported some cosmetic changes from libpng-1.4.0rc01, changing
|
|
many "#if defined(x)" to "#ifdef x" in png.h and pngconf.h.
|
|
|
|
version 1.2.41beta08 [October 30, 2009]
|
|
Ported from libpng-1.4.0rc01: png_calloc(), png_get_io_chunk_name(),
|
|
png_get_io_state(), png_set_user_cache_max(), png_get_user_cache_max(),
|
|
png_set_premultiply_alpha, and png_do_read_premultiply_alpha().
|
|
Relocated png_do_chop() ahead of building gamma tables in pngrtran.c
|
|
This avoids building 16-bit gamma tables unnecessarily.
|
|
|
|
version 1.2.41beta09 [November 1, 2009]
|
|
Removed a harmless extra png_set_invert_alpha() from pngwrite.c
|
|
More bugfixes and improvements to CMakeLists.txt (Philip Lowman)
|
|
Moved CMakeLists.txt from scripts into the main libpng directory.
|
|
Apply png_user_chunk_cache_max within png_decompress_chunk().
|
|
Merged libpng-1.2.41.txt with libpng-1.4.0.txt where appropriate.
|
|
|
|
version 1.2.41beta10 [November 1, 2009]
|
|
Enabled iTXt support by default. To ensure binary compatibility with
|
|
previous versions, the "lang" and "lang_key" members will be assumed
|
|
to be omitted from previous versions unless the current libpng
|
|
version was built with PNG_iTXt_SUPPORTED (which is otherwise no
|
|
longer necessary to gain iTXt support), as a signal that the user has
|
|
been building previous versions with PNG_iTXt_SUPPORTED as well.
|
|
|
|
version 1.2.41beta11 [November 2, 2009]
|
|
Store user's user_png_ver in new png_ptr->user_png_ver element.
|
|
Revised iTXt support. To ensure binary compatibility with
|
|
previous versions, the "lang" and "lang_key" members will be assumed
|
|
to be omitted from versions prior to 1.2.41beta11 whenever there is a
|
|
library mismatch.
|
|
|
|
version 1.2.41beta12 [November 2, 2009]
|
|
Free png_ptr->user_png_ver when destroying png_ptr.
|
|
|
|
version 1.2.41beta13 [November 3, 2009]
|
|
Updated scripts/pngw32.def and projects/wince/png32ce.def
|
|
Copied projects/wince/png32ce.def to the scripts directory.
|
|
Added scripts/makefile.wce
|
|
Patched ltmain.sh for wince support.
|
|
Added PNG_CONVERT_tIME_SUPPORTED macro.
|
|
|
|
version 1.2.41beta14 [November 8, 2009]
|
|
versions 1.2.41beta05 through 1.2.41beta13 were abandoned.
|
|
Make inclusion of time.h in pngconf.h depend on PNG_CONVERT_tIME_SUPPORTED
|
|
Make #define PNG_CONVERT_tIME_SUPPORTED depend on PNG_WRITE_tIME_SUPPORTED
|
|
Reverted iTXt compatibility stuff from 1.2.41beta05, 1.2.41beta11, and
|
|
1.2.41beta12.
|
|
Reverted IOSTATE feature, user_cache_max, and premultiply_alpha features
|
|
from 1.2.41beta08.
|
|
Retained png_calloc() from 1.2.41beta08 but as a non-exported function,
|
|
and removed reference to png_calloc from scripts/*.def
|
|
|
|
version 1.2.41beta15 [November 8, 2009]
|
|
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).
|
|
Updated scripts/makefile* to add "-DPNG_CONFIGURE_LIBPNG" to CFLAGS,
|
|
to prevent warnings about direct access to png structs by libpng
|
|
functions while building libpng. They need to be tested, especially
|
|
those using compilers other than gcc.
|
|
Updated projects/visualc6 and visualc71 with "/d PNG_CONFIGURE_LIBPNG".
|
|
|
|
version 1.2.41beta16 [November 9, 2009]
|
|
Removed three direct references to read_info_ptr members in pngtest.c
|
|
that were detected by the new PNG_DEPSTRUCT macro.
|
|
Only #define PNG_DEPSTRUCT, etc. in pngconf.h if not already defined.
|
|
|
|
version 1.2.41beta17 [November 10, 2009]
|
|
Updated CMakeLists.txt to add "-DPNG_CONFIGURE_LIBPNG" to the definitions.
|
|
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
|
|
Added "-DPNG_CONFIGURE_LIBPNG" to the contrib/pngminum makefiles.
