Trace the edge. Check the repair.
Load a PNG and define its sprites, or open the demo. Compare sampled colors, then keep the checked repair.
Choose a PNG to start. No images or results are loaded.
Run a sweep, then pin a pixel to inspect its source colors.
Sampling uses a smaller image level (mip). The effective level is the one actually available. Colors blend between nearby pixels within that level, without blending between mip levels.
Choose a sprite and run a sweep to measure its edges.
Not tested
Pinned pixel evidence
Click a pixel in either view, or choose an edge sample. On a focused canvas, use arrow keys to move the pinned pixel and Enter or Space to select the worst sample. Arrow keys move between sample buttons; Enter pins the selected sample.
No pixel pinned.
