Why not just do what I did with the gear tooth counting project and turn the
image map into a heightfield. Then you can scan around it with trace () and
compile a list of points.
Obviously this would only scan the exterior envelope, and so a method to get the
holes in letters like B, D, O, P, Q, and R would be required. Maybe a stepwise
trace () across a vector accumulating a crossing number could be used to find
holes and start a sub-scan in the second "outside" region.
