Aspect Ratio vs X/Y Range [message #64973]

I'm wondering if the specification of the x/y ranges (along with the x/
y style keyword) interfere with the position=aspect keyword? Does
anybody know?
I'd like to specify the range for a close-up of an image but still
preserve the aspect ratio of the full (unzoomed) image.
Thanks

Unless I am missing something, it sounds to me like you
are talking about apples and oranges here. How do
line plots have anything to do with images?

In any case, probably TVIMAGE is your friend, since
with it you can position your image or subimage in
any aspect ratio you like by manipulating the POSITION
keyword.
