I am using a number of Sparcstations under Sunview. Some of the Sparcs are
1 bit monochrome and some are 8 bit gray scale. From within a program how
can you tell which frame buffer your system has?

For a window you get a pointer to the Pixwin struct using window_get: Canvas canvas; Pixwin *pw; pw = (Pixwin *)window_get(canvas,WIN_PIXWIN); For a canvas use canvas_pixwin: pw = (Pixwin *)canvas_pixwin(canvas); In ether case the frame buffer depth can be found in: pw->pw_pixrect->pr_depth See page 108 of ther SunView Programmers Guide: "Is My Application Running on a Color Display?" -- Larry Martell "Opinions are like assholes; everybody has one, 212-668-9478 but nobody wants to look at the other guys" uunet!st-andy!larry
