   Re:  flaw calling imagemask

   At least 2 flaws:

   1. imagemask does not deposit image at current point,
      so your first line should read '100 100 translate';

   2. It scans your image into a 1 unit square, so you should have a line
      to scale it, something like:

            368 300 div 72 mul  384 300 div 72 mul scale

      to draw it pixel for pixel;

    What you got was 1 pt by 1 pt image at (0,0) which is off the imageable area.


    Re: your earlier question regarding images:

    I too would like to know if one can persuade PostScript to leave images alone.
    That seems like a fair bit of work, scan-converting all those little
    rectangles onto the page image (in your case 368*384=141312 of them).  Even
    though the LaserWriter, for one, is amazingly fast at doing all that work,
    it would be nice to tell it not to do the work at all.
