color balance

Balance colors through samples indicated as gray.

March 16, 2013 - 06:46 — kvrijt

This little script was inspired by "GIMP tutorial - advanced color correction using sample point and curves" which nicely describes a method to get the color balance of a drawable right.
It expects an active path. If it's not there it exits unceremoniously.
The average RGB values of a 5 pixel radius area around the points in the path are taken and from these color adjustment curves are invoked with the aim to equalize them and thereby get the color balance right.
