-Drawing the symbol for entrance pits which uses a double line. Currently I generate points at a fixed distance perpendicular to the given line and connect them to form the inner line. This results in very bad behaviour at edges, and needs a lot of memory due to the large number of generated points. Any ideas how to solve that? Simple trick: thick black line at background and thin white line at foreground on the identical path.
Good idea, yet I forgot to mention that the outer line should be thicker (like a wall), than the inner line (pit). An 'asymmetric pen' could solve that, but I dont know if that is possible... regards Georg
