-------------------------------------------------------------------------------- Fedora EPEL Update Notification FEDORA-EPEL-2020-6c93c61069 2020-11-29 01:18:44.734368 --------------------------------------------------------------------------------
Name : pngcheck Product : Fedora EPEL 8 Version : 2.4.0 Release : 2.el8 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.
