Has anyone out there successfully displayed an image in OpenWindows without using pw_ calls? I can't find any examples that do this and everything I've tried simply core dumps. If you have, would you PLEASE send (or post) sample code? Thanks. -- Alan # "But seriously, what could go wrong?" ..!cit-vax!elroy!alan alan@elroy.jpl.nasa.gov

The sample code that comes with XView (on expo) has a complete directory full of examples that do this and many other things that people are asking here. These are the same examples used in the XView Programmer's Manual (Volume 7 of O'Reilly && Associates Series on X books). dan ----------------------------------------------------------- O'Reilly && Associates argv@sun.com / argv@ora.com 632 Petaluma Ave, Sebastopol, CA 95472 800-338-NUTS, in CA: 800-533-NUTS, FAX 707-829-0104

Just use XPutImage(display, xid, gc, image, src_x, src_y, dst_x, dst_y, width, height); i.e. canvas = xv_create(frame, CANVAS, CANVAS_REPAINT_PROC, canvas_repaint, CANVAS_X_PAINT_WINDOW, TRUE, ... canvas_repaint(canvas, pw, display, xid, xrects) Canvas canvas; Xv_Window pw; Display *display; Window xid; Xv_xrectlist *xrects; { ... XPutImage(display, xid, gc, image, 0, 0, x, y, w, h); ... Regards, Heather

Colors should be set up with X calls too in place of pixwin calls. In XView the color-map-segment code finds a contigious block of free color space and puts the color table there. The pw_rop command calls XPutImage, but adds the color table offset to each pixel in the XImage data before XPutImage and subtracts it after.
