Have a look at ContrastZoom from my program library.
This shows you how 16-bit image data can be displayed
in multiple windows in object graphics.

hi David,
I looked at your program but u have drawn some different views in
one scene and displayed that in one window. Is that the only way we
can do it?
In direct graphics
tvscl, image
tvscl, image1
will draw two images in two windows. I want to do that but in object
graphics. Please tell me if that's possible.
Regards,
Akhila.
