Name : pngcheck
Product : Fedora 32
Version : 2.4.0
Release : 8.fc32
URL : http://www.libpng.org/pub/png/apps/pngcheck.html
Summary : Verifies the integrity of PNG, JNG and MNG files
Description :
pngcheck verifies the integrity of PNG, JNG and MNG files (by checking the
internal 32-bit CRCs [checksums] and decompressing the image data); it can
optionally dump almost all of the chunk-level information in the image in
human-readable form. For example, it can be used to print the basic statistics
about an image (dimensions, bit depth, etc.); to list the color and
transparency info in its palette (assuming it has one); or to extract the
embedded text annotations. This is a command-line program with batch
capabilities.
The current release supports all PNG, MNG and JNG chunks, including the newly
approved sTER stereo-layout chunk. It correctly reports errors in all but two
of the images in Chris Nokleberg's brokensuite-20061204.
