Hi all

I was searching on the web, but i didn't find an answer to my problem.
I need to make a subset on an image using

coordinates, but i can't find a way to do it. I see this method

http://groups.google.es/group/comp.lang.idl-pvwave/browse_fr m/thread/9e5d6eb8b5bac80f?tvc=1
and this other (very

similar) http://www.mombu.com/programming/idl/t-subset-an-image-by-ro i-in-idl-1613495.html,
but don't use

coordinates, use an evf file.

IDL/ENVI has a widget that use only two coordinates to cut (upper-left
and lower-right coordinate), but it isn't

fully automatically.

Is there any function to cut the image with set coordinates and save
it in a new file?

I really hope you can help me... I'm not a programmer and this
sometimes it's very hard

Thanks!

Alvaro
