Hi, Jari Aalto.

Here is a cygport file, which could be a candidate for pngcheck-3.0.2.

Regards,

Lem

----------------
NAME="pngcheck"
VERSION=3.0.2
RELEASE=1
CATEGORY="Graphics"
SUMMARY="PNG file format checker"
DESCRIPTION="\
pngcheck verifies the integrity of PNG, JNG and MNG files (by checking
the internal 32-bit CRCs, a.k.a. 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.
