You know, I think this whole thing has to be a lot
easier than this.
Ben is getting the data from Label_Region, which returns
regions labeled with a single value (or "color", as I
prefer to think of them). Why not just use the CONTOUR
command to draw a contour around the region, then use
the information in all those PATH_**** keywords to
find the perimeter? With clever programming (I'll
leave this part to Ben) you can find all the holes
in the data, etc.
I think I might even have a piece of code around here
where I did this once. If I get some time (unlikely
today) I'll have a look around.
