PNG or JPG. Closed outlines work best — use the Fix-gaps tool for breaks.

Detection

Line darkness

Ignore regions smaller than px

Colors (line art only)

Code regions touching the edge (background)

Manual colors, moved labels, and your color key are kept when regions re-detect.

Color key

Click a row to select it for the Assign tool. Edit codes and names freely.

Advanced: custom region codes

Give a color several codes (comma-separated) and its regions rotate through them — e.g. key code 10 with region codes 5+5, 6+4, 7+3 for a math-facts worksheet. The key box keeps showing the main code. Leave blank for normal numbering.
