Hi David,

Craig's method is much more elegant than this one, but I find it useful.

After you draw the contours around your blobs then create a blank pixmap of
the same size as the image. (I am guessing that you are using device
coordinates) Then draw the contour to the pixmap in a single color like 255.
Do an im= TVRD() to get a new image and then do an indices = where( im eq
255). Turn these back to x,y coords and you have a very nearly evenly
spaced series of points.
