Does anyone know of an existing tool for designing simple polygons? I'm thinking of something with a basic click-to-add-points functionality that will export the points in a n x,y,x,y,x,y format. I don't want to reinvent the wheel if this already exists.
Also, has anyone ever tried to extract polygons based on image data? For instance, in a 2D-map war game, you could use this to automatically detect and define the shape/location of territories on user-created map images. I've thought of a few ways to do this, mostly based on using image colors to find borders, but the ways I come up with are either ridiculously complicated or break down under certain circumstances.
