Re^2: Polygon Creation -- Request for Algorithm Suggestions

I don't think the OP really wants a hull and if then it wouldn't be convex. (Though stated otherwise)

It seems to be about tracing the - often concave - outline of a compact set of points - the pixel image of a county.

A hull is more general, it doesn't require that the enclosed points are connected.

Thanks for the clarification. I guess at latest while looking at the map of Italy I should have realized that "convex" is not a good description...	[reply]
