Here is a typical photo, quantized to 16 colors:

Hi, all,
Today I finally got an initial (very rough) ability to scan an image multiple times, and produce multiple paths.
The trace option I added today does:
- Quantizes a bitmap into a reduced number of colors or shades of gray
- Separates out each color, and traces it (much like taking
four-color art to your local print shop). 3) Scans each one, applies the color to it. 4) Assembles them as a <g>roup.
It seems to do fairly well with simple images, but complex ones have a "Potrace problem". What I mean is that since Potrace traced an estimate around each region, the reassembled curves do not exactly tile together again. You might need a background shade or something to keep the white background from peeking through.
But give it a try. It should be a bit of fun.
If anyone can think of a good general algorithm for stitching together two adjacent curves, give it a try.
There will be more stuff later, of course. The 'differing levels of brightness' thing will be added soon.
