READ_GAMMA. Prior to 1.6.0 switching off READ_GAMMA did unpredictable things to the interfaces that use it (specifically, png_do_background in 1.4 would simply display composite for grayscale images but do composition with the incorrect arithmetic for color ones). In 1.6 the semantic of -DPNG_NO_READ_GAMMA is changed to simply disable any interface that depends on it; this obliges people who set it to consider whether they really want it off if they happen to use any of the interfaces in question (typically most users who disable it won't).

management system (CMS). In practice it is not possible to obtain cHRM information reliably using just the end-point tags because they do not exist in the vast majority of profiles. Instead it is necessary to run the endpoints through the ICC colorimetric intent transform (as described in the v4 spec). Since this is likely to be too much code inside libpng for too little gain (it implies a fairly complete CMS implementation) the code has been changed to allow an external CMS to be used. This code is temporarily disabled until a suitable set of test cases using one or more external CMS implementations have been implemented.

type rules. By the ANSI-C standard the new types should be identical to the previous versions, and all known versions of gcc tested with the previous versions except for GCC-4.2.1 work with this version. The change makes the ANSI-C rule that const applied to an array of elements applies instead to the elements in the array moot by explicitly applying const to the base elements of the png_icc_matrix and png_icc_vector types. The accidental (harmless) 'const' previously applied to the parameters of two of the functions have also been removed.

fixed Cygwin+MSVC build errors. The ICC profile handling now includes more checking. Several errors that caused rejection of the profile are now handled with a warning in such a way that the invalid profiles will be read by default in release (but not pre-RC) builds but will not be written by default. The easy part of handling a cHRM chunk is written, where the ICC profile contains the required data. The more difficult part plus guessing a gAMA value requires code to pass selected RGB values through the profile.

option to pngtest. The "--relaxed" option turns off the benign errors that are enabled by default in pre-RC builds. makepng can now write ICC profiles where the length has not been extended to a multiple of 4, and pngtest now intercepts all libpng errors, allowing the previously-introduced "--strict test" on no warnings to actually work.

contrib/libtests/makepng: corrected 'rgb' and 'gray' cases. profile_error messages could be truncated; made a correct buffer size calculation and adjusted pngerror.c appropriately. png_icc_check_* checking improved; changed the functions to receive the correct color type of the PNG on read or write and check that it matches the color space of the profile (despite what the comments said before, there is danger in assuming the app will cope correctly with an RGB profile on a grayscale image and, since it violates the PNG spec, allowing it is certain to produce inconsistent app behavior and might even cause app crashes.) Check that profiles contain the tags needed to process the PNG (tags all required by the ICC spec). Removed unused PNG_STATIC from pngpriv.h.

png_handle_unknown() when SAVE support is absent. Moved the shell test scripts for contrib/libtests from the libpng top directory to contrib/libtests. png_handle_unknown() must always read or skip the chunk, if SAVE_UNKNOWN_CHUNKS is turned off *and* the application does not set a user callback an unknown chunk will not be read, leading to a read error, which was revealed by the "tunknown" test.

libpng handling of unknown chunks other than vpAg and sTER (including unsafe-to-copy chunks which were dropped before) and eliminates the repositioning of vpAg and sTER in pngtest.png by changing pngtest.png (so the chunks are where libpng would put them).

png_set_keep_unknown_chunks() to be turned off if not required and causes both read and write to behave appropriately (on read this is only possible if the user callback is used to handle unknown chunks). The change also removes the support for storing unknown chunks in the info_struct if the only unknown handling enabled is via the callback, allowing libpng to be configured with callback reading and none of the unnecessary code.

control of the unknown handling, corrects the pre-existing bug where the per-chunk 'keep' setting is ignored and makes it possible to skip IDAT chunks in the sequential reader (broken in earlier 1.6 versions). There is a new test program, test-unknown.c, which is a work in progress (not currently part of the test suite). Comments in the header files now explain how the unknown handling works.
