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 Removed the synopses from libpngpf.3 because they - were out of date and no longer useful.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. + Removed two useless #ifdef directives from pngread.c and one from pngrutil.c + Always put the CMAKE_LIBRARY in "lib" (removed special WIN32 case). + Removed empty vstudio/pngstest directory (Clifford Yapp). + Eliminated redundant png_push_read_tEXt|zTXt|iTXt|unknown code from + pngpread.c and use the sequential png_handle_tEXt, etc., in pngrutil.c; + now that png_ptr->buffer is inaccessible to applications, the special + handling is no longer useful. + Fixed bug with png_handle_hIST with odd chunk length (Frank Busse). + Added PNG_SAFE_LIMITS feature to pnglibconf.dfa and code in pngconf.h + to reset the user limits to safe ones if PNG_SAFE_LIMITS is defined. + To enable, use "CPPFLAGS=-DPNG_SAFE_LIMITS_SUPPORTED" on the configure + command or put "#define PNG_SAFE_LIMITS_SUPPORTED" in pnglibconf.h. + Revised the SAFE_LIMITS feature to be the same as the feature in libpng16. + Added information about the new limits in the manual. + Updated Makefile.in + Removed unused "current_text" members of png_struct and the png_free() + of png_ptr->current_text from pngread.c + Fixed PNG_LIBPNG_BUILD_BASE_TYPE definition. + Fixed CMF optimization of non-IDAT compressed chunks, which was added at + libpng-1.5.4. It sometimes produced too small of a window. + Reject all iCCP chunks after the first, even if the first one is invalid. + Added palette-index checking. Issue a png_benign_error() if an invalid + index is found. + Revised example.c to put text strings in a temporary character array + instead of directly assigning string constants to png_textp members. + This avoids compiler warnings when -Wwrite-strings is enabled. + Prevent PNG_EXPAND+PNG_SHIFT doing the shift twice. + Revised png_set_text_2() to avoid potential memory corruption (fixes + CVE-2011-3048).
