A strict ANSI system does not have + snprintf, and the "__STRICT_ANSI__" detects that condition more reliably + than __STDC__ (John Bowler). + Removed the PNG_PTR_NORETURN attribute because it too dangerous. It tells + the compiler that a user supplied callback (the error handler) does not + return, yet there is no guarantee in practice that the application code + will correctly implement the error handler because the compiler only + issues a warning if there is a mistake (John Bowler). + Removed the no-longer-used PNG_DEPSTRUCT macro. + Updated the zlib version to 1.2.5 in the VStudio project. + Fixed 64-bit builds where png_uint_32 is smaller than png_size_t in + pngwutil.c (John Bowler). + Fixed bug with stripping the filler or alpha channel when writing, that + was introduced in libpng-1.5.2 (bug report by Andrew Church). + Updated pngtest.png with the new zlib CMF optimization. + Cleaned up conditional compilation code and of background/gamma handling + Internal changes only except a new option to avoid compiling the + png_build_grayscale_palette API (which is not used at all internally.) + The main change is to move the transform tests (READ_TRANSFORMS, + WRITE_TRANSFORMS) up one level to the caller of the APIs. This avoids + calls to spurious functions if all transforms are disabled and slightly + simplifies those functions. Pngvalid modified to handle this. + A minor change is to stop the strip_16 and expand_16 interfaces from + disabling each other; this allows the future alpha premultiplication + code to use 16-bit intermediate values while still producing 8-bit output. + png_do_background and png_do_gamma have been simplified to take a single + pointer to the png_struct rather than pointers to every item required + from the png_struct. This makes no practical difference to the internal + code. + A serious bug in the pngvalid internal routine 'standard_display_init' has + been fixed - this failed to initialize the red channel and accidentally + initialized the alpha channel twice. + Changed png_struct jmp_buf member name from png_jmpbuf to tmp_jmpbuf to + avoid a clash with the png_jmpbuf macro on some platforms. + Added appropriate feature test macros to ensure libpng sees the correct API + _POSIX_SOURCE is defined in pngpriv.h, pngtest.c and pngvalid.c to ensure + that POSIX conformant systems disable non-POSIX APIs. _ISOC99_SOURCE is + defined in pngpriv.h to obtain the ISO C99 snprintf definition, when + available. + Removed png_snprintf and added formatted warning messages. This change adds + internal APIs to allow png_warning messages to have parameters without + requiring the host OS to implement snprintf. As a side effect the + dependency of the tIME-supporting RFC1132 code on stdio is removed and + PNG_NO_WARNINGS does actually work now. + Added PNG_WRITE_OPTIMIZE_CMF_SUPPORTED macro to make the zlib "CMF" byte + optimization configureable. + Internal functions were added to claim/release the z_stream and, hopefully, + make the code more robust. Also deflateEnd checking is added - previously + libpng would ignore an error at the end of the stream. + Removed the -D_ALL_SOURCE from definitions for AIX in CMakeLists.txt + Implemented premultiplied alpha support: png_set_alpha_mode API + Added expand_16 support to the high level interface. + Added named value and 'flag' gamma support to png_set_gamma. Made a minor + change from the previous (unreleased) ABI/API to hide the exact value used + for Macs - it's not a good idea to embed this in the ABI! + Moved macro definitions for PNG_HAVE_IHDR, PNG_HAVE_PLTE, and PNG_AFTER_IDAT + from pngpriv.h to png.h because they must be visible to applications + that call png_set_unknown_chunks(). + Check for up->location !PNG_AFTER_IDAT when writing unknown chunks + before IDAT. + Improved "pngvalid --speed" to exclude more of pngvalid from the time. + Documented png_set_alpha_mode(), other changes in libpng.3/libpng-manual.txt + The cHRM chunk now sets the defaults for png_set_rgb_to_gray() (when negative + parameters are supplied by the caller), while in the absence of cHRM + sRGB/Rec 709 values are still used. + The bKGD chunk no longer overwrites the background value set by + png_set_background(), allowing the latter to be used before the file + header is read. It never performed any useful function to override + the default anyway. + Added memory overwrite and palette image checks to pngvalid.c + Previously palette image code was poorly checked. Since the transformation + code has a special palette path in most cases this was a severe weakness. + Minor cleanup and some extra checking in pngrutil.c and pngrtran.c. When + expanding an indexed image, always expand to RGBA if transparency is + present. + Reversed earlier 1.5.3 change of transformation order; move png_expand_16 + back where it was. The change doesn't work because it requires 16-bit + gamma tables when the code only generates 8-bit ones. This fails + silently; the libpng code just doesn't do any gamma correction. Moving + the tests back leaves the old, inaccurate, 8-bit gamma calculations, but + these are clearly better than none! + png_set_background() and png_expand_16() did not work together correctly. + This problem is present in 1.5.2; if png_set_background is called with + need_expand false and the matching 16 bit color libpng erroneously just + treats it as an 8-bit color because of where png_do_expand_16 is in the + transform list. This simple fix reduces the supplied colour to 8-bits, + so it gets smashed, but this is better than the current behavior. + Added tests for expand16, more fixes for palette image tests to pngvalid. + Corrects the code for palette image tests and disables attempts to + validate palette colors. + Fixed uninitialized memory read in png_format_buffer() (Bug report by + Frank Busse, related to CVE-2004-0421). + Fixed png_handle_sCAL which is broken in 1.5; added sCAL to pngtest.png + Revised documentation about png_set_user_limits() to say that it also affects + png writing. + Revised handling of png_set_user_limits() so that it can increase the + limit beyond the PNG_USER_WIDTH|HEIGHT_MAX; previously it could only + reduce it. + Make the 16-to-8 scaling accurate. Dividing by 256 with no rounding is + wrong (high by one) 25% of the time. Dividing by 257 with rounding is + wrong in 128 out of 65536 cases. Getting the right answer all the time + without division is easy. + Added "_SUPPORTED" to the PNG_WRITE_CUSTOMIZE_ZTXT_COMPRESSION macro. + Added projects/owatcom, an IDE project for OpenWatcom to replace + scripts/makefile.watcom. This project works with OpenWatcom 1.9. The + IDE autogenerates appropriate makefiles (libpng.mk) for batch processing. + The project is configurable, unlike the Visual Studio project, so long + as the developer has an awk. + Changed png_set_gAMA to limit the gamma value range so that the inverse + of the stored value cannot overflow the fixed point representation, + and changed other things OpenWatcom warns about. + Revised pngvalid.c to test PNG_ALPHA_MODE_SUPPORTED correctly. This allows + pngvalid to build when ALPHA_MODE is not supported, which is required if + it is to build on libpng 1.4. + Removed string/memory macros that are no longer used and are not + necessarily fully supportable, particularly png_strncpy and png_snprintf. + Added log option to pngvalid.c and attempted to improve gamma messages. + People found the presence of a beta release following an rc release + to be confusing; therefore we bump the version to libpng-1.5.4beta01 + and there will be no libpng-1.5.3 release. + Moved definitions of PNG_HAVE_IHDR, PNG_AFTER_IDAT, and PNG_HAVE_PLTE + outside of an unknown-chunk block in png.h because they are also + needed for other uses. + Added png_set_scale_16() API, to match inaccurate results from previous + libpng versions, configurable with PNG_READ_SCALE_16_TO_8_SUPPORTED. + Fixed a problem in png_do_expand_palette() exposed by optimization in + 1.5.3beta06 + Also removed a spurious and confusing "trans" member ("trans") from png_info. + The palette expand optimization prevented expansion to an intermediate RGBA + form if tRNS was present but alpha was marked to be stripped; this exposed + a check for tRNS in png_do_expand_palette() which is inconsistent with the + code elsewhere in libpng. + Added PNG_TRANSFORM_SCALE_16 to the high-level read transforms. + If PNG_READ_16_TO_8_ACCURATE_SCALE is not enabled, png_set_scale_16() + and png_do_scale_16_to_8() aren't built. + Revised contrib/visupng, gregbook, and pngminim to demonstrate scale_16_to_8 + Fixed pngvalid, simplified macros, added checking for 0 in sCAL. + The ACCURATE scale macro is no longer defined in libpng-1.5 - call the + png_scale_16_to_8 API. Made sure that PNG_READ_16_TO_8 is still defined + if the png_strip_16_to_8 API is present. png_check_fp_number now + maintains some state so that positive, negative and zero values are + identified. sCAL uses these to be strictly spec conformant. + Define PNG_ALLOCATED to "restrict" only if MSC_VER >= 1400. - Enabled iTXt support (changes png_struct, thus requires so-number change). - Cleaned up PNG_ASSEMBLER_CODE_SUPPORTED vs PNG_MMX_CODE_SUPPORTED - Eliminated PNG_1_0_X and PNG_1_2_X macros. - Removed deprecated functions png_read_init, png_write_init, png_info_init, - png_permit_empty_plte, png_set_gray_1_2_4_to_8, and removed the - deprecated macro PNG_MAX_UINT. - Moved "PNG_INTERNAL" parts of png.h and pngconf.h into pngintrn.h - Removed all WIN32_WCE #ifdefs except those involving the - time.h "tm" structure (Cosmin) - Reduced dependency on C-runtime library when on Windows (Simon-Pierre) - Replaced sprintf() with png_sprintf() (Simon-Pierre) - Revised makefiles to avoid making links to libpng.so.* - Added a note in libpng.txt that png_set_sig_bytes(8) can be used when - writing an embedded PNG without the 8-byte signature. - Updated scripts/pngos2.def, pngw32.def, and projects/wince/png32ce.def - Added PNG_NO_GET_INT_32 and PNG_NO_SAVE_INT_32 macros. - Scripts/libpng.pc.in contained "configure" style version info and would - not work with makefiles. - Increased sprintf buffer from 50 to 52 chars in pngrutil.c to avoid - buffer overflow. - Fixed bug in example.c (png_set_palette_rgb -> png_set_palette_to_rgb)) - Changed sonum from 0 to 1. - Removed unused prototype for png_check_sig() from png.h - Prepended "#! /bin/sh" to ltmail.sh and contrib/pngminus/*.sh (Cosmin). - Avoided potential buffer overflow and optimized buffer in - png_write_sCAL(), png_write_sCAL_s() (Cosmin). - Removed the include directories and libraries from CFLAGS and LDFLAGS - in scripts/makefile.gcc (Nelson A. de Oliveira, Cosmin). - Exported png_write_sig (Cosmin). - Optimized buffer in png_handle_cHRM() (Cosmin). - Allow zero-length IDAT chunks after the entire zlib datastream, but not - after another intervening chunk type. - Set pHYs = 2835 x 2835 pixels per meter, and added - pngtest now produces, and made some cosmetic changes to pngtest output. - sCAL = 0.352778e-3 x 0.352778e-3 meters, in pngtest.png (Cosmin). - Added png_set_benign_errors(), png_benign_error(), png_chunk_benign_error(). - Revised INSTALL and autogen.sh - Fixed typo in several makefiles (-W1 should be -Wl) - Added typedef for png_int_32 and png_uint_32 on 64-bit systems. - Added one zero element to png_gamma_shift[] array in pngrtran.c to avoid - reading out of bounds. - Added demonstration of user chunk support in pngtest.c, to support the - public sTER chunk and a private vpAg chunk. - Removed ordinals from scripts/pngw32.def and removed png_info_int and - png_set_gray_1_2_4_to_8 entries. - Inline call of png_get_uint_32() in png_get_uint_31(). - Removed WINCE and Netware projects. - Removed standalone Y2KINFO file. - Removed AC_FUNC_MALLOC from configure.ac. - Added a warning when writing iCCP profile with mismatched profile length. - Patched pnggccrd.c to assemble on x86_64 platforms. - Moved chunk header reading into a separate function png_read_chunk_header() - in pngrutil.c.

Now "configure" - needs nothing from the "scripts" directory. - 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. - 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. - Removed obsolete comments about ASM from projects/visualc71/README_zlib.txt - Align row_buf on 16-byte boundary in memory. - 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) - Changed "/255" to "/255.0" in background calculations to make it clear - that the 255 is used as a double. - Added "#define PNG_NO_PEDANTIC_WARNINGS" in the libpng source files. - 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/libpng14 instead of in - $prefix/include/libpng/libpng14. - Added "bit_depth" parameter to the private png_build_gamma_table() function. - Use png_calloc() instead of png_malloc(); png_memset() in pngrutil.c - Avoid deprecated references to png_ptr-io_ptr and png_ptr->error_ptr - in pngtest.c +Send comments/corrections/commendations to png-mng-implement at lists.sf.net +(subscription required; visit +https://lists.sourceforge.net/lists/listinfo/png-mng-implement +to subscribe) +or to glennrp at users.sourceforge.net + +Glenn R-P +*/ } +#endif Send comments/corrections/commendations to png-mng-implement at lists.sf.net -(subscription required; visit +(subscription required; visit https://lists.sourceforge.net/lists/listinfo/png-mng-implement to subscribe) or to glennrp at users.sourceforge.net |
