wrong (high by one) 25% of the time. Dividing by 257 with rounding is wrong in 128 out of 65536 cases. Getting the right answer all the time without division is easy.

libpng-manual.txt. The cHRM chunk now sets the defaults for png_set_rgb_to_gray() (when negative parameters are supplied by the caller), while in the absence of cHRM sRGB/Rec 709 values are still used. The bKGD chunk no longer overwrites the background value set by png_set_background(), allowing the latter to be used before the file header is read. It never performed any useful function to override the default anyway. Send comments/corrections/commendations to png-mng-implement at lists.sf.net: (subscription required; visit

minor change from the previous (unreleased) ABI/API to hide the exact value used for Macs - it's not a good idea to embed this in the ABI!

that this only affects how composited pixels are returned to the calling application; they don't affect the pixels that are written to a PNG file.

This was because the attempt to reset the zlib stream in png_write_IDAT happened after the first IDAT chunk had been deflated - much too late. In this change internal functions are added to claim/release the z_stream and, hopefully, make the code more robust. Also deflateEnd checking is added - previously libpng would ignore an error at the end of the stream.

This change adds internal APIs to allow png_warning messages to have parameters without requiring the host OS to implelment snprintf. As a side effect the dependency of the RFC1132 code on stdio is removed and PNG_NO_WARNINGS does actually work now.

handling. Internal changes only except for a new option to avoid compiling in the png_build_grayscale_palette API (which is not used at all internally.) The main change is to move the transform tests (READ_TRANSFORMS, WRITE_TRANSFORMS) up one level to the caller of the APIs.
