Has anyone ever used rastor data with PHIGS on a Sun?? I'm trying to put a rastor (pixrect) image as the background of a PHIGS canvas, and draw on the background using PHIGS. The problem is repairing the background that PHIGS does not know about....quickly. One way to do it is to refresh the background and then tell PHIGS to redisplay all posted structures. How can I force PHIGS to redisplay all posted structures? Postall seems to be smart enough to know if an element is already displayed, not to redisplay it. Any information is greatly appreciated. I will post any solutions. Thanks, Jim Hopkins Please respond via E-Mail to uunet!melpar!jim
