[] I need to create a program that reads CIF (Caltech Intermediate Form) files (which describe VLSI mask-level geometry) and then writes a PostScript file that is a "plot" of the geometry. I need to be able to plot either 32 colors or 32 gray-scale stipple patterns, preferably in a device-independent manner. In other words, can I create a PostScript file that will take advantage of a Color PostScript printer while at the same time will use stipple patterns if using a Black-and-White PostScript pattern? My second question involves OR'ing these stipple patterns. When rectangles overlap, I need to make sure that the user sees them as overlapping. It looks like when I create a new filled-rectangle, it over-writes the area that overlaps. How do I handle this situation, without having to search for all rectangle intersections and creating a new pattern? If possible, I would also like this to work for color... i.e. a new color is created when two overlap. Thanks for all your help! Please respond via e-mail, as this is probably not of general Net-Use. (Pretty awesome play on words, eh?) -- Glenn Lewis glennl@vlsi.caltech.edu <OR> glewis%pcocd2.intel.com@Relay.CS.Net
