Encode normalized Sobel luminance-gradient directions as an RGB normal-map PNG.
Render local colour from the most populated bounded luminance bin.
Scale every existing alpha value uniformly and export a transparency-safe PNG.
Create a deterministic one-bit image with a repeating 4x4 Bayer threshold matrix.
Create a tonal line sketch from grayscale, local averaging, inversion, and bounded color dodge.
Report visible decoded-luminance percentiles and their robust p95-minus-p5 span.
Report exact-RGBA horizontal and vertical run counts, means, and maxima.
Sort qualifying contiguous row pixels by luminance above an explicit threshold.
Report exact visible decoded RGBA tuple count and proportion.
Create an adjustable mosaic-style pixel effect.
Reduce each still-image colour channel to a selected number of levels.
Check effective PPI at a chosen print width, measure decoded transparency and export a JSON review before print handoff.
