專案描述

pngcheck is the official PNG tester and debugger. Originally designed simply to test the CRCs within a PNG image file (e.g., to check for ASCII rather than binary transfer), it has since been extended to check and optionally print almost all the information about a PNG image and to verify that it conforms to the PNG specification. It also includes partial support for MNG animations.

2.1.0

This version adds support for all remaining MNG
and JNG chunks, as well as for the new PNG/MNG
sTER (stereo-image) chunk. It also includes two
new GPL'd utilities, one to split a PNG/MNG/JNG
into its constituent chunks (numbered for easy
reassembly) and one to fix minor zlib-header
breakage in images created with libpng 1.2.6.

2.0.0

This release enables stringent zlib testing regardless of the verbosity level, which reduces the danger of hidden failures. It also adds support for the MNG TERM chunk, updates support for the SAVE and BACK chunks, incorporates patches for Mac OS and RISC OS, and fixes a number of bugs.
