Fixed bug introduced in libpng-1.4.0beta48 with the memset arguments
|
|
for pcal_params.
|
|
Fixed order of #ifdef directives in the png_debug defines in png.h
|
|

version 1.4.0beta50 [March 18, 2009]

|
|
reading an interlaced file, to avoid a possible UMR.
|
|
Undid recent revision of PNG_NO_STDIO version of png_write_flush(). Users
|
|
having trouble with fflush() can build with PNG_NO_WRITE_FLUSH defined
|
|
or supply their own flush_fn() replacement.
|
|
Revised libpng*.txt and png.h documentation about use of png_write_flush()
|
|
and png_set_write_fn().

Fixed potential memory leak of "new_name" in png_write_iCCP() (Ralph Giles)
|
|
|
|
version 1.4.0beta54 [April 13, 2009]
|
|
Added "ifndef PNG_SKIP_SETJMP_CHECK" block in pngconf.h to allow
|
|
application code writers to bypass the check for multiple inclusion
|
|
of setjmp.h when they know that it is safe to ignore the situation.
|
|
Eliminated internal use of setjmp() in pngread.c and pngwrite.c
|
|
Reordered ancillary chunks in pngtest.png to be the same as what
|
|
pngtest now produces, and made some cosmetic changes to pngtest output.
|

Eliminated deprecated png_read_init_3() and png_write_init_3() functions.
|
|

|
|
"shadowed declaration" warning from gcc-4.3.3.
|
|
Renamed "gamma" to "png_gamma" in pngset.c to avoid "shadowed declaration"
|
|
warning about a global "gamma" variable in math.h on some platforms.
|
|
|
|
version 1.4.0beta57 [May 2, 2009]
|
|
Removed prototype for png_freeptr() that was added in libpng-1.4.0beta24
|
|
but was never defined (again).

|
|
in beta57).
|

|
|
progressive readers.
|
|
Added contrib/pngminim/preader to demonstrate building minimal progressive
|
|
decoder, based on contrib/gregbook with embedded libpng and zlib.
|
|
|
|
version 1.4.0beta61 [May 20, 2009]
|
|
In contrib/pngminim/*, renamed "makefile.std" to "makefile", since there
|
|
is only one makefile in those directories, and revised the README files
|
|
accordingly.
|
|
More reformatting of comments, mostly to capitalize sentences.
|
|
|
|
version 1.4.0beta62 [June 2, 2009]

Reformatted several remaining "else statement" into two lines.
|
|
Added a section to the libpng documentation about using png_get_io_ptr()
|
|
in configure scripts to detect the presence of libpng.

|
|
version 1.4.0beta63 [June 15, 2009]
|
|
Revised libpng*.txt and libpng.3 to mention calling png_set_IHDR()
|
|
multiple times and to specify the sample order in the tRNS chunk,
|
|
because the ISO PNG specification has a typo in the tRNS table.
|
|
Changed several PNG_UNKNOWN_CHUNK_SUPPORTED to
|
|
PNG_HANDLE_AS_UNKNOWN_SUPPORTED, to make the png_set_keep mechanism
|
|
available for ignoring known chunks even when not saving unknown chunks.
|
|
Adopted preference for consistent use of "#ifdef" and "#ifndef" versus
|
|
"#if defined()" and "if !defined()" where possible.
|
|
|
|
version 1.4.0beta64 [June 24, 2009]
|
|
Eliminated PNG_LEGACY_SUPPORTED code.
|
|
Moved the various unknown chunk macro definitions outside of the
|
|

version 1.4.0beta69 [July 25, 2009]

common "PNG_ALL_FILTERS" and PNG_FILTER_NONE cases.

version 1.4.0beta90 [November 2, 2009]
|
|
Removed all remaining WIN32_WCE #ifdefs except those involving the

|
|
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".

|
Moved the synopsis lines for png_read_destroy(), png_write_destroy()

so that only PNG_EXPORT functions are exported.
|
|
Removed the deprecated png_check_sig() function/macro.
|
|
Removed recently removed function names from scripts/*.def
|
|
Revised pngtest.png to put chunks in the same order written by pngtest
|
|
(evidently the same change made in libpng-1.0beta54 was lost).
|
|
Added PNG_PRIVATE macro definition in pngconf.h for possible future use.
|
|
|
|
version 1.4.0beta97 [November 13, 2009]
|
|
Restored pngtest.png to the libpng-1.4.0beta7 version.

|
|
Moved libpng-config.in and libpng.pc-configure.in out of the scripts
|
|
directory, to libpng-config.in and libpng-pc.in, respectively, and
|
|
modified Makefile.am and configure.ac accordingly. Now "configure"
|
|
needs nothing from the "scripts" directory.

version 1.4.0beta100 [November 14, 2009]
|
|
Removed ASM builds from projects/visualc6 and projects/visualc71

|
|
accidentally deleted from the zip and 7z distributions when the xcode
|
|
project was added.
