While playing with the AT&T graphviz library again, I was trying to get nodes to show up as pictures, which is fairly simple:
node [peripheries=0, fontsize=10, shapefile="computer.gif"]
However, what I really want is a transparent gif (computer.gif) and then using background color to color that node. That way I could programmatically change the color of the nodes and still use icons to make the nodes a bit nicer. This is what I tried:
node [peripheries=1, fontsize=10, shapefile="computer.gif", fillcolor=blue]
Unfortunately it did not work. Anyone?
