Well - i have not tested it so i can't really tell. In general i think filtering an image to create a plain b&w mask from a noisy color drawing is a task completely different and well separable from vectorization. I am usually a fan of the Unix philosophy of having separate tools for different tasks. One real shortcoming of potrace is that it can only deal with two different area types (i.e. two colors) - if anyone knows an open source tools with a similar feature set that does not have this limitation i would be eager to hear. -- Christoph Hormann http://www.imagico.de/ _______________________________________________ talk mailing list talk@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk
