Hey guys,
I'm hoping you can help me with a project I'm doing. I've used a fractal world map generator (http://www.bin.sh/gaming/tools/world.cgi) to come up with a few continents for a project I'm doing. However, not being much of an artist, I'm at a loss as to how to accomplish something I'm looking to do.

I would like to take the image that is created with that web site (it's a gif), open it up in gimp or PaintShop Pro (those are the 2 I have), and click a button that will outline the continents and islands. Then, I would like to get rid of all the colors so that I simply have outlines, and can fill the continents and oceans in with the colors of my choice. I found a way to do it with paint.net - simply load the image, then click "effects -> Outline," and it does it, then I use the color replacer to get rid of the colors. Unfortunately, the outlines in paint.net don't show up as vectors, so when you zoom in really close, it's very "blobby." Any advice? Or can you point me in a direction that maybe I don't know about yet?

Thanks!
