Hello X World! I have heard that in order to use memory pixrects with X11/NeWS, I MUST use the PIXWIN interface "as a compatibility veneer over Xlib." What I am trying to accomplish is the following: 1) Use X11 as the user interface 2) Use memory PIXRECTS as the process for displaying high resolution graphics. I realize that I canot use this client remotely, but that is a decision that has been made. I want to use the memory PIXRECTs because of the difference in speed achieved in using PIXRECTs over X. (X is 10 times slower!!) 3) Use X as the complete window manager, with the PIXRECT images being drawn in these X windows. Therefore I want to avoid using the PIXWIN interface, and the Notifier. The problem that I have run into is that if I take an image contained in a memory pixrect, and use the pr_rop routine to display the image to the screen (while running X11/NeWS) the system crashes. (The system is a SPARC Station 1) Is there some kind of preparation of the screen that I should perform before displaying the pixrect image? (for example, locking the screen?) Is it possible to avoid using the PIXWIN interface? Does anyone have any similar code that they have written that I may use as an example?` Any information would be greatly appreciated. Signed Frustrated!!!
