- 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.
