The Postscript device has a much higher resolution than, say, the X graphics
device. I suspect that your problem is that the ww array is just not big enough
for Postscript output, resulting in the lines being so close together at the
higher resolution that it looks like its filled. Try making ww=bytarr(100,100)
and see what happens. You can adjust it as suits you.
