Can the underlying algorithm used in CONTOUR be accessed somehow?
I need a quick and dirty contour finding algorithm, but I actually need the contour paths as data (i.e. rather than just plotting them on an image). The algorithm that CONTOUR uses would be fine, but I can't see that this can be called independently to return some data describing the contour path. Is there some other contour finding implementation out there?

Try the IsoContour procedure. Cheers, David -- David Fanning, Ph.D. Fanning Software Consulting, Inc. Coyote's Guide to IDL Programming: http://www.idlcoyote.com/ Sepore ma de ni thue.
