Hi
Here is a demonstration that might give you some ideas ...
library(grImport)
PostScriptTrace("flower.ps", "flower.xml")
flower <- readPicture("flower.xml")
grid.newpage()
grid.picture(flower)
# Extract each path, then look at the 'summary' for the path
for (i in 1:flower@summary@numPaths) {
bb <- flower[i]@summary
# Draw the result as a check
grid.polygon(c(bb@xscale[1], bb@xscale[2],
bb@xscale[2], bb@xscale[1]),
c(bb@yscale[1], bb@yscale[1],
bb@yscale[2], bb@yscale[2]),
default.units="native",
gp=gpar(col=NA, fill=adjustcolor(i, alpha=.5)),
vp="picture.shape::picture.scale")
}
The flower.ps file in that example is available here ...

Hope that helps.
