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 Removed the synopses from libpngpf.3 because they - were out of date and no longer useful.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. + Re-initialize the zlib compressor before compressing non-IDAT chunks. + Added API functions to set parameters for zlib compression of non-IDAT + chunks. + Updated scripts/symbols.def with new API functions. + Only compile the new zlib re-initializing code when text or iCCP is + supported, using PNG_WRITE_COMPRESSED_TEXT_SUPPORTED macro. + Improved the optimization of the zlib CMF byte (see libpng-1.2.6). + Optimize the zlib CMF byte in non-IDAT compressed chunks + Fixed gcc -ansi -pedantic compile.

See the PNG specification for more detail. It is +important to note that when an image with an alpha channel is +scaled, linear encoded, pre-multiplied component values must +be used! + +The remaining modes assume you don't need to do any further color correction or +that if you do your color correction software knows all about alpha (it +probably doesn't!) + + PNG_ALPHA_STANDARD: The data libpng produces is encoded in the standard way +assumed by most correctly written graphics software. +The gamma encoding will be removed by libpng and the +linear component values will be pre-multiplied by the +alpha channel. + +With this format the final image must be re-encoded to +match the display gamma before the image is displayed. +If your system doesn't do that, yet still seems to +perform arithmetic on the pixels without decoding them, +it is broken - check out the modes below. + +With PNG_ALPHA_STANDARD libpng always produces linear +component values, whatever screen_gamma you supply. The +screen_gamma value is, however, used as a default for +the file gamma if the PNG file has no gamma information. + +If you call png_set_gamma() after png_set_alpha_mode() you +will override the linear encoding. Instead the +pre-multiplied pixel values will be gamma encoded but +the alpha channel will still be linear. This may +actually match the requirements of some broken software, +but it is unlikely. + +While linear 8-bit data is often used it has +insufficient precision for any image with a reasonable +dynamic range. To avoid problems, and if your software +supports it, use png_set_expand_16() to force all +components to 16 bits. + + PNG_ALPHA_OPTIMIZED: This mode is the same as PNG_ALPHA_STANDARD except that +completely opaque pixels are gamma encoded according to +the screen_gamma value. Pixels with alpha less than 1.0 +will still have linear components. + +Use this format if you have control over your +compositing software and do don't do other arithmetic +(such as scaling) on the data you get from libpng. Your +compositing software can simply copy opaque pixels to +the output but still has linear values for the +non-opaque pixels. + +In normal compositing, where the alpha channel encodes +partial pixel coverage (as opposed to broad area +translucency), the inaccuracies of the 8-bit +representation of non-opaque pixels are irrelevant. + +You can also try this format if your software is broken; +it might look better. + + PNG_ALPHA_BROKEN: This is PNG_ALPHA_STANDARD however all component values, +including the alpha channel are gamma encoded. This is +an appropriate format to try if your software, or more +likely hardware, is totally broken: if it performs +linear arithmetic directly on gamma encoded values. + +In most cases of broken software or hardware the bug in the final display +manifests as a subtle halo around composited parts of the image. You may not +even perceive this as a halo; the composited part of the image may simply appear +separate from the background, as though it had been cut out of paper and pasted +on afterward. + +If you don't have to deal with bugs in software or hardware, or if you can fix +them, there are three recommended ways of using png_set_alpha_mode(): + + png_set_alpha_mode(png_ptr, PNG_ALPHA_PNG, + screen_gamma); + +You can do color correction on the result (libpng does not currently +support color correction internally.)
