1706.0. "XGetImage - BadMatch" by MARX::FLEMING (AFE - Acronyms For Everything) Thu Nov 09 1989 09:57

<Also posted in DECWINDOWS_PROGRAMMING>

    The following code gives me a BadMatch error when I try
    to do the XGetImage.  The window is InputOutput and the other
    reasons for this error don't seem to apply to what I'm doing.  Which
    is: 1) create a window 2) manage it 3) XGetImage on the window.
    Ideas?
    Code fragment...
    .
    .
	toplevel = XtInitialize(
		"test",
		"message", 
		NULL, 0,
		&argc, argv);

    	main_window = DwtMainWindow(toplevel, "test", 0, 0, 900, 575);
	display_window = DwtWindow (main_window, "test", 0, 0, 900, 575, NULL);

        argcount = 0;
    	SetArg(DwtNexposeCallback, expose_cb);
        XtSetValues(display_window, arglist, argcount);

	XtManageChild (main_window);
        XtManageChild (display_window);
	XtRealizeWidget (toplevel);
    	dpy = XtDisplay(toplevel);
    	screen = DefaultScreen (dpy);

    	format = (DisplayPlanes (dpy ,screen) > 1 ? ZPixmap : XYPixmap);

	image = XGetImage(XtDisplay(toplevel),
			XtWindow(display_window),
    				0 ,0 ,900 ,525 ,AllPlanes, format);
	XtMainLoop();
}

This is the error I get...

Have you tried it on both an 8-plane and a 1-plane system?

Just tried it on an 8-plane system and got the same error.
