Unfortunately, that doesn't work when the picture contains different
colors. You would then have to decompose the picture into parts
consisting of only one color and place them one after another. The
problem showed up to me when using contour.sty, which does a good job in
preparing graphics for presentations. You can use it to raise contrast
when writing stuff on a background pattern. I'd love to see one of the
patches discussed here included in dvitomp.
