I'n not sure I know exactly what you have in mind, but you can use
the DEFROI function to manually draw a contour on an image. The
code might look like this:

TV, image
s = SIZE(image)
junk = DEFROI(s(1), s(2), xvert, yvert, /NoRegion, /NoFill, /Restore)

Your "contour" will be described by the x and y points in the xvert and yvert
variables.

Cheers!
