cleya diff
Compare two rendered frames — where they differ (bounding box), by how much (per-channel max), a PSNR score, and a difference image amplified to the change it actually contains
cleya diff --a before.png --b after.png --output diff.png
Options

|---|---|---|
--a | First image (before) | required · string |

--threshold | Ignore differences below this level when locating the changed region (default 1) | string |
--overwrite | Overwrite output file if it exists | boolean |
Category: perception — instruments — measure what was rendered (WCAG contrast, alignment, brand conformance, copy claims, pixel diff)
