for each pixel of your image.
Plug-in Menu Location:
1. Have an image with a layer of the image you'd like to create Colour Explosion/Abstract Pixel of.
2. You might want to open Window/Dockable Dialogs/Error Console so that you don't get annoying pop-ups but see messages in error console.
3. Change your brush to "2. Hardness 100" unless of course you want to experiment with other brushes but I just use "2. Hardness 100" because I want a solid line to represent each pixel.
4. Run plug-in
Python-Fu/Abs Pixels.... There are no options so it just runs and outputs messages.
4. That's it. Now go take a nap or two because it's really slow, it'll print out every 1000 lines/pixels it's done with in error Console so you get a good idea of how far it's coming along.
