That is the routine we use, I set a flag with a keypress ("I") and save the
screen in a post-render call-back. This method gives the added advantage
that it gets the raster image before the X-Cursor is added to the display
(excellent for presentation printing)....

      if (VTR->snapimage) {
     VTR->snapimage=0;
     i=0;
     do {
          sprintf(temp,"scrn_capt/pic%d.rgb",i++);
     } while (!access(temp,0));
     pfuSaveImage(temp,0,0,1600,1200,0);
      }

This is an older version of the routine, the latest actually measures the
screen-size, but I cannot remember the function calls and the current
sources are not available at the moment....
