Hi there all Khoros freaks,

I have a question concerning the "cutting" of subimages from an image.
Editimage provides the means to extract a rectangular part of any image,
but for MANY applications this seems insufficient, at least to me.
Has anyone ever written an xvroutine to cut more complicated
structures, say unions of polygons, from a displayed image
interactively?  (The selected region may then be masked by a newly
created binary image, or the rest clipped to 0.0, or whatever...)

If so, I would be very grateful to hear about it.
(I hope this is a common problem.)
Thanks.
