png-cmp: like cmp for PNGs
14 hours ago
- png-cmp is a tool that checks if two PNG images are visually equivalent, inspired by the cmp command.
- Usage: png-cmp a.png b.png; it exits silently if identical and gives an error if different.
- Unlike cmp, it compares pixel data rather than binary data, ignoring metadata like text.
- The tool was built for an experiment requiring visual identity checks of PNGs.
