description Validate and inspect PNG, JNG and MNG files
long_description ${name} 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.
