What is pngcheck FOR LINUX?
pngcheck verifies the integrity of PNG, JNG and MNG files (by checking the internal 32-bit CRCs [checksums] and decompressing the image data); pngcheck 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.
All PNG and JNG chunks are supported, plus almost all MNG chunks (everything but PAST, MAGN, DISC, DROP, DBYK, ORDR, and pHYg). This is a command-line program with batch capabilities (e.g., "pngcheck *.png").
