2018-08-18Remove top-level const from function-scope variablesCosmin Truta
As per the const correctness rules, top-level const-ness of data in automatic scopes does not propagate outside of these scopes (unlike const-ness at lower levels, such as pointers to const data). Previously, const was used liberally, but inconsistently across the libpng codebase. Using const wherever applicable is not incorrect. However, _consistent_ use of const is difficult to maintain in such conditions. In conclusion, we shall continue to use const only where doing so is strictly necessary: 1. If a function guarantees that it will not modify an argument passed by pointer, the corresponding function parameter should be a pointer-to-const (const T *). 2. Static data should not be modified, therefore it should be const. Reference: Google C++ Style Guide https://google.github.io/styleguide/cppguide.html#Use_of_const
2018-08-18Replace the remaining uses of PNG_CONST with constCosmin Truta
In v1.6.0, compiler support for const became a requirement. It should be used consistently. To maintain backwards compatibility, PNG_CONST is still maintained in deprecated form.

2017-07-11[libpng16] Removed one of the GCC-7.1.0 'strict-overflow' warnings thatJohn Bowler
result when integers appear on both sides of a compare. Worked around the others by forcing the strict-overflow setting in the relevant functions to a level where they are not reported. Changed "FALL THROUGH" comments to "FALLTHROUGH" because GCC doesn't like the space. Worked around some C-style casts from (void*) because g++ 5.4.0 objects to them. Increased the buffer size for 'sprint' to pass the gcc 7.1.0 'sprint overflow' check that is on by default with -Wall -Wextra.

2012-10-25[libpng16] Changed ICC profile support to allow use of an external colorJohn Bowler
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.
2012-08-25[libpng16] Cleaned up and corrected ICC profile handling.John Bowler
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.
