Live validation
against the actual rulebook.
Every crop is measured against the published tolerance ranges for the selected document. Pass or warn, in real time — no "submit and hope."
The same checks the authority will run — before you submit.
- Face height & eye line measured from the pupil midpoint with sub-pixel accuracy, clamped to the tolerance range your authority publishes.
- Background colour checked across a sampled grid — catches gradients and fringe from poor segmentation (ΔE < 3 against spec).
- File-size ceiling enforced per-spec — recompressed silently for sub-60 KB e-visa portals, lossless for print.
- Sharpness & expression guards warn on blur, closed eyes, or non-neutral expressions before you export.
