Could anyone give some hints on how to display overlapping pixmaps (depth 8), with colour, such that the foreground colours from the two pixmaps do not combine to get a different colour. Currently I can overlap two pixmaps (displaying, removing, displaying, removing, ...) using XCopyArea with All_Planes and GXxor and that works great except that the where the foreground colours overlap the colours combine to show a different colour. I would like the last pixmap displayed to be the top colour. I am sure it can be done because the cursor is implemented so that it's foreground colour is always on top and you can "see through" the background colour to view the underlying graphics. I am using X11 R3 with 386/ix on an AT&T 386. Thanks in advance. Jay Graham Software Kinetics Ltd., Ottawa, Ontario, Canada, jgraham@crc.skl.dnd.ca
