When I load a [some random color] and white picture, IGP doesn seem to work right. Whats going on?
The problem with white is a known “feature”. The problem stems from my use of black/white images as a matte – black is the area to be painted, white is the area to be left behind. When IGP was first created, the program was extremely slow, and I was able to boost the speed by either 25% or 33% (I don’t remember which) if I was willing to give up the use of white as a color. Needless to say, I chose speed. The workaround for this is to not use white. Change the white to an off-white and you’ll be fine.
