src/Source/LibPNG/CHANGES  view on Meta::CPAN

    those using compilers other than gcc.
  Updated projects/visualc6 and visualc71 with "/d PNG_CONFIGURE_LIBPNG".
    They should work but still need to be updated to remove
    references to pnggccrd.c or pngvcrd.c and ASM building.
  Added README.txt to the beos, cbuilder5, netware, and xcode projects warning
    that they need to be updated, to remove references to pnggccrd.c and
    pngvcrd.c and to depend on pngpriv.h
  Removed three direct references to read_info_ptr members in pngtest.c
    that were detected by the new PNG_DEPSTRUCT macro.
  Moved the png_debug macro definitions and the png_read_destroy(),
    png_write_destroy() and png_far_to_near() prototypes from png.h
    to pngpriv.h (John Bowler)
  Moved the synopsis lines for png_read_destroy(), png_write_destroy()
    png_debug(), png_debug1(), and png_debug2() from libpng.3 to libpngpf.3.

Version 1.4.0beta94 [November 9, 2009]
  Removed the obsolete, unused pnggccrd.c and pngvcrd.c files.
  Updated CMakeLists.txt to add "-DPNG_CONFIGURE_LIBPNG" to the definitions.
  Removed dependency of pngtest.o on pngpriv.h in the makefiles.
  Only #define PNG_DEPSTRUCT, etc. in pngconf.h if not already defined.

Version 1.4.0beta95 [November 10, 2009]
  Changed png_check_sig() to !png_sig_cmp() in contrib programs.
  Added -DPNG_CONFIGURE_LIBPNG to contrib/pngminm/*/makefile
  Changed png_check_sig() to !png_sig_cmp() in contrib programs.
  Corrected the png_get_IHDR() call in contrib/gregbook/readpng2.c
  Changed pngminim/*/gather.sh to stop trying to remove pnggccrd.c and pngvcrd.c
  Added dependency on pngpriv.h in contrib/pngminim/*/makefile

Version 1.4.0beta96 [November 12, 2009]
  Renamed scripts/makefile.wce to scripts/makefile.cegcc
  Revised Makefile.am to use libpng.sys while building libpng.so
    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.
  Removed projects/beos and netware.txt; no one seems to be supporting them.
  Revised Makefile.in

Version 1.4.0beta98 [November 13, 2009]
  Added the "xcode" project to zip distributions,
  Fixed a typo in scripts/pngwin.def introduced in beta97.

Version 1.4.0beta99 [November 14, 2009]
  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.
  Avoid redefining PNG_CONST in pngconf.h

Version 1.4.0beta100 [November 14, 2009]
  Removed ASM builds from projects/visualc6 and projects/visualc71
  Removed scripts/makefile.nommx and makefile.vcawin32
  Revised CMakeLists.txt to account for new location of libpng-config.in
    and libpng-pc.in
  Updated INSTALL to reflect removal and relocation of files.

Version 1.4.0beta101 [November 14, 2009]
  Restored the binary files (*.jpg, *.png, some project files) that were
    accidentally deleted from the zip and 7z distributions when the xcode
    project was added.

Version 1.4.0beta102 [November 18, 2009]
  Added libpng-config.in and libpng-pc.in to the zip and 7z distributions.
  Fixed a typo in projects/visualc6/pngtest.dsp, introduced in beta100.
  Moved descriptions of makefiles and other scripts out of INSTALL into
    scripts/README.txt
  Updated the copyright year in scripts/pngwin.rc from 2006 to 2009.

Version 1.4.0beta103 [November 21, 2009]
  Removed obsolete comments about ASM from projects/visualc71/README_zlib.txt
  Align row_buf on 16-byte boundary in memory.
  Restored the PNG_WRITE_FLUSH_AFTER_IEND_SUPPORTED guard around the call
    to png_flush() after png_write_IEND().  See 1.4.0beta32, 1.4.0beta50
    changes above and 1.2.30, 1.2.30rc01 and rc03 in 1.2.41 CHANGES.  Someone
    needs this feature.
  Make the 'png_jmpbuf' macro expand to a call that records the correct
    longjmp function as well as returning a pointer to the setjmp
    jmp_buf buffer, and marked direct access to jmpbuf 'deprecated'.
    (John Bowler)

Version 1.4.0beta104 [November 22, 2009]
  Removed png_longjmp_ptr from scripts/*.def and libpng.3
  Rebuilt configure scripts with autoconf-2.65

Version 1.4.0beta105 [November 25, 2009]
  Use fast integer PNG_DIVIDE_BY_255() or PNG_DIVIDE_BY_65535()
    to accomplish alpha premultiplication when
    PNG_READ_COMPOSITE_NODIV_SUPPORTED is defined.
  Changed "/255" to "/255.0" in background calculations to make it clear
    that the 255 is used as a double.

Version 1.4.0beta106 [November 27, 2009]
  Removed premultiplied alpha feature.

Version 1.4.0beta107 [December 4, 2009]
  Updated README
  Added "#define PNG_NO_PEDANTIC_WARNINGS" in the libpng source files.
  Removed "-DPNG_CONFIGURE_LIBPNG" from the makefiles and projects.
  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.

Version 1.4.0beta108 [December 11, 2009]
  Removed leftover "-DPNG_CONFIGURE_LIBPNG" from contrib/pngminim/*/makefile
  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 1.4.0beta109 [December 13, 2009]
  Added "bit_depth" parameter to the private png_build_gamma_table() function.
  Pass bit_depth=8 to png_build_gamma_table() when bit_depth is 16 but the
    PNG_16_TO_8 transform has been set, to avoid unnecessary build of 16-bit
    tables.

src/Source/LibPNG/CHANGES  view on Meta::CPAN

    a variety of images, limited documentation (in the header file.)
  Installed more accurate linear to sRGB conversion tables. The slightly
    modified tables reduce the number of 16-bit values that
    convert to an off-by-one 8-bit value.  The "makesRGB.c" code that was used
    to generate the tables is now in a contrib/sRGBtables sub-directory.

Version 1.5.7beta03 [November 17, 2011]
  Removed PNG_CONST from the sRGB table declarations in pngpriv.h and png.c
  Added run-time detection of NEON support.
  Added contrib/libtests; includes simplified API test and timing test and
    a color conversion utility for rapid checking of failed 'pngstest' results.
  Multiple transform bug fixes plus a work-round for double gamma correction.
    libpng does not support more than one transform that requires linear data
    at once - if this is tried typically the results is double gamma
    correction. Since the simplified APIs can need rgb to gray combined with
    a compose operation it is necessary to do one of these outside the main
    libpng transform code. This check-in also contains fixes to various bugs
    in the simplified APIs themselves and to some bugs in compose and rgb to
    gray (on palette) itself.
  Fixes for C++ compilation using g++ When libpng source is compiled
    using g++. The compiler imposes C++ rules on the C source; thus it
    is desireable to make the source work with either C or C++ rules
    without throwing away useful error information.  This change adds
    png_voidcast to allow C semantic (void*) cases or the corresponding
    C++ static_cast operation, as appropriate.
  Added --noexecstack to assembler file compilation. GCC does not set
    this on assembler compilation, even though it does on C compilation.
    This creates security issues if assembler code is enabled; the
    work-around is to set it by default in the flags for $(CCAS)
  Work around compilers that don't support declaration of const data. Some
    compilers fault 'extern const' data declarations (because the data is
    not initialized); this turns on const-ness only for compilers where
    this is known to work.

Version 1.5.7beta04 [November 17, 2011]
  Since the gcc driver does not recognize the --noexecstack flag, we must
    use the -Wa prefix to have it passed through to the assembler.
    Also removed a duplicate setting of this flag.
  Added files that were omitted from the libpng-1.5.7beta03 zip distribution.

Version 1.5.7beta05 [November 25, 2011]
  Removed "zTXt" from warning in generic chunk decompression function.
  Validate time settings passed to pngset() and png_convert_to_rfc1123()
    (Frank Busse).
  Added MINGW support to CMakeLists.txt
  Reject invalid compression flag or method when reading the iTXt chunk.
  Backed out 'simplified' API changes. The API seems too complex and there
    is a lack of consensus or enthusiasm for the proposals.  The API also
    reveals significant bugs inside libpng (double gamma correction and the
    known bug of being unable to retrieve a corrected palette). It seems
    better to wait until the bugs, at least, are corrected.
  Moved pngvalid.c into contrib/libtests
  Rebuilt Makefile.in, configure, etc., with autoconf-2.68

Version 1.5.7rc01 [December 1, 2011]
  Replaced an "#if" with "#ifdef" in pngrtran.c
  Revised #if PNG_DO_BC block in png.c (use #ifdef and add #else)

Version 1.5.7rc02 [December 5, 2011]
  Revised project files and contrib/pngvalid/pngvalid.c to account for
    the relocation of pngvalid into contrib/libtests.
  Revised pngconf.h to use " __declspec(restrict)" only when MSC_VER >= 1400,
    as in libpng-1.5.4.
  Put CRLF line endings in the owatcom project files.

Version 1.5.7rc03 [December 7, 2011]
  Updated CMakeLists.txt to account for the relocation of pngvalid.c

Version 1.5.7 [December 15, 2011]
  Minor fixes to pngvalid.c for gcc 4.6.2 compatibility to remove warnings
    reported by earlier versions.
  Fixed minor memset/sizeof errors in pngvalid.c.

Version 1.6.0beta01 [December 15, 2011]
  Removed machine-generated configure files from the GIT repository (they will
    continue to appear in the tarball distributions and in the libpng15 and
    earlier GIT branches).
  Restored the new 'simplified' API, which was started in libpng-1.5.7beta02
    but later deleted from libpng-1.5.7beta05.
  Added example programs for the new 'simplified' API.
  Added ANSI-C (C90) headers and require them, and take advantage of the
    change. Also fixed some of the projects/* and contrib/* files that needed
    updates for libpng16 and the move of pngvalid.c.
    With this change the required ANSI-C header files are assumed to exist: the
    implementation must provide float.h, limits.h, stdarg.h and stddef.h and
    libpng relies on limits.h and stddef.h existing and behaving as defined
    (the other two required headers aren't used).  Non-ANSI systems that don't
    have stddef.h or limits.h will have to provide an appropriate fake
    containing the relevant types and #defines.
  The use of FAR/far has been eliminated and the definition of png_alloc_size_t
    is now controlled by a flag so that 'small size_t' systems can select it
    if necessary.  Libpng 1.6 may not currently work on such systems -- it
    seems likely that it will ask 'malloc' for more than 65535 bytes with any
    image that has a sufficiently large row size (rather than simply failing
    to read such images).
  New tools directory containing tools used to generate libpng code.
  Fixed race conditions in parallel make builds. With higher degrees of
    parallelism during 'make' the use of the same temporary file names such
    as 'dfn*' can result in a race where a temporary file from one arm of the
    build is deleted or overwritten in another arm.  This changes the
    temporary files for suffix rules to always use $* and ensures that the
    non-suffix rules use unique file names.

Version 1.6.0beta02 [December 21, 2011]
  Correct configure builds where build and source directories are separate.
    The include path of 'config.h' was erroneously made relative in pngvalid.c
    in libpng 1.5.7.

Version 1.6.0beta03 [December 22, 2011]
  Start-up code size improvements, error handler flexibility. These changes
    alter how the tricky allocation of the initial png_struct and png_info
    structures are handled. png_info is now handled in pretty much the same
    way as everything else, except that the allocations handle NULL return
    silently.  png_struct is changed in a similar way on allocation and on
    deallocation a 'safety' error handler is put in place (which should never
    be required).  The error handler itself is changed to permit mismatches
    in the application and libpng error buffer size; however, this means a
    silent change to the API to return the jmp_buf if the size doesn't match
    the size from the libpng compilation; libpng now allocates the memory and
    this may fail.  Overall these changes result in slight code size
    reductions; however, this is a reduction in code that is always executed
    so is particularly valuable.  Overall on a 64-bit system the libpng DLL
    decreases in code size by 1733 bytes.  pngerror.o increases in size by
    about 465 bytes because of the new functionality.
  Added png_convert_to_rfc1123_buffer() and deprecated png_convert_to_rfc1123()
    to avoid including a spurious buffer in the png_struct.
