Hi,
Zooming in place is one feature that does not seem to be popular with
IDL users. It is really strange that we are satisfied with the zoomed
image being in another window. That does not allow us to work with the
zoomed image. We can just view at the zoom image. I would like to zoom
on an image, in place and not in a separate window, and then work on
this image and if need be, zoom back. But, I am using a draw widget to
work with the image. That might seem to make things more complex.
I have seen David's Zimage program and I think I could play around with
it and with some modifications, I will be able to use it.
Any thoughts on this one?
Thanks,
Pravesh

Sorry, I haven't read the entery thread and perhaps this answer has been
answered previous.
Why not implementing zooming in place with object graphics. Now (at
work) we are developing an aplication to show topography and some
meteorological information as 2D but implemented with object grpahics.
Things like zooming in place and space coordenates are relatively simple
with them.
Bye.

No, dammit. How many years do I have to wait for that
epiphany!?
Cheers,
David
P.S. My wife thinks it probably has something to do with me not
getting enough balls on the other side of the net, but what
does she know about it? :-(

Did you ever work out why you lost the tennis match?
