G’MIC Colorize lineart smart coloring node

This documentation is for version 0.3 of G’MIC Colorize lineart smart coloring.


Global geometry parameters:

Set Contour erosion to -1 for erosion based on automatic estimation of stroke thickness.

Add strokes with a saturated color having value 255 (e.g. pure red) on your lineart allows to guide the colorization algorithm with virtual contours.

For Random colors mode only:

For color spots mode only:

Connection parameters:

Hatch detection: (work-in-progress, still slow!)
