It contains all features required to handle the entirety of the PngSuite by Willem van Schack.

The pngcheck utility is a small demonstration binary that checks and prints metadata on every .png image provided via parameter. You can run it (for example on the test directories) with

cargo run --release --example pngcheck ./tests/pngsuite/*
