The selection? What selection? Did the OP or me talk about selection? > and doesn't work at all on medium gray or b/w dithered patterns. Yes, every method has its pros and cons, but XOR is probably most efficient. > for most cases, "marching ants" is a much better approach (usually done > by drawing alternating stippled patterns). see e.g. Where "most cases" depends on application. I'd be very upset to see, say, 5-6 highly intersecting scientific plots on the same picture drawn using the "marching ants" approach. Besides, the marching ants doesn't work for printing :( -- Sergei. -- http://mail.python.org/mailman/listinfo/python-list
