They need to be tested, especially - those using compilers other than gcc. - Updated CMakeLists.txt to add "-DPNG_CONFIGURE_LIBPNG" to the definitions. - 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. - Removed the obsolete, unused pnggccrd.c and pngvcrd.c files. - Removed dependency of pngtest.o on pngpriv.h in the makefiles. - 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 - 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 - Added PNG_PRIVATE macro definition in pngconf.h for possible future use. - Removed projects/beos and netware.txt; no one seems to be supporting them. - 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. - 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 + Added description of png_set_crc_action() to the manual. + Added a note in the manual that the type of the iCCP profile was changed + from png_charpp to png_bytepp in png_get_iCCP(). Similarly, + it was changed from png_charpp to png_const_bytepp in png_set_iCCP(). + Ensure that png_rgb_to_gray ignores palette mapped images, if libpng + internally happens to call it with one. + Fixed the failure to handle palette mapped images correctly. + Fixed a bug in handling of interlaced images (bero at arklinux.org). + Updated CMakeLists.txt (Clifford Yapp) + Fixed typecasting of some png_debug() statements (Cosmin) + Updated documentation of png_set|get_tRNS() (Thomas Klausner). + Mentioned in the documentation that applications must #include "zlib.h" + if they need access to anything in zlib.h, and that a number of + macros such as png_memset() are no longer accessible by applications. + Corrected pngvalid gamma test "sample" function to access all of the color + samples of each pixel, instead of sampling the red channel three times. + Changed variable names index, div, exp, and gamma to char_index, divisor, + exp_b10, and gamma_val, respectively, to avoid "shadow" warnings. + Prevent png_push_crc_skip() from hanging while reading an unknown chunk + or an over-large compressed zTXt chunk with the progressive reader. + Eliminated more GCC "shadow" warnings. + Revised png_fixed() in png.c to avoid compiler warning about reaching the + end without returning anything. + In the manual, describe the png_get_IHDR() arguments in the correct order. + Added const_png_structp and const_png_infop types, and used them in + prototypes for most png_get_*() functions. + Added png_get_io_chunk_type() and deprecated png_get_io_chunk_name() + Added synopses for the IO_STATE functions and other missing synopses + to the manual. Removed the synopses from libpngpf.3 because they + were out of date and no longer useful. Better information can be + obtained by reading the prototypes and comments in pngpriv.h + Attempted to fix cpp on Solaris with S. Studio 12 cc, fix build + Added a make macro DFNCPP that is a CPP that will accept the tokens in + a .dfn file and adds configure stuff to test for such a CPP. ./configure + should fail if one is not available. + Corrected const_png_ in png.h to png_const_ to avoid polluting the namespace. + Added png_get_current_row_number and png_get_current_pass_number for the + benefit of the user transform callback. + Added png_process_data_pause and png_process_data_skip for the benefit of + progressive readers that need to stop data processing or want to optimize + skipping of unread data (e.g. if the reader marks a chunk to be skipped.) + Enhanced pngvalid, corrected an error in gray_to_rgb, corrected doc error. + pngvalid contains tests of transforms, which tests are currently disabled + because they are incompletely tested. gray_to_rgb was failing to expand + the bit depth for smaller bit depth images; this seems to be a long + standing error and resulted, apparently, in invalid output. The + documentation did not accurately describe what libpng really does when + converting RGB to gray. + Fixed incorrect examples of callback prototypes in the manual, that were + introduced in libpng-1.0.0. + In addition the order of the png_get_uint macros with respect to the + relevant function definitions has been reversed. This helps the + preprocessing of the symbol files be more robust. Furthermore, the + symbol file preprocessing now uses -DPNG_NO_USE_READ_MACROS even when + the library may actually be built with PNG_USE_READ_MACROS; this stops + the read macros interfering with the symbol file format. + Made the manual, synopses, and function prototypes use the function + argument names file_gamma, int_file_gamma, and srgb_intent consistently. + Changed PNG_UNUSED from "param=param;" to "(void)param;". + Added transform tests to pngvalid and simplified the arguments. + Added a request in the manual that applications do not use "png_" or + "PNG_" to begin any of their own symbols.
