Image Object ROI selection [message #12578]

Greetings. I'm new to this news group and IDL programming so hopefully
I won't bore you all with bone-headed questions (I know you do too).

I'm trying to update an old MRI image analysis program that was written
for pre-5.0 IDL. I'd like to use object graphics as much as possible,
but can't figure out if there is a way to select ROI's of an image
object. Data picking will give me one point, but I need the ability to
select polygon, square, and circle ROI's of an image. The CW_DEFROI and
DEFROI procedures don't like the draw widget since it seems to be
treated as an object itself (with the graphics_level set to 2).

Any thoughts or do I just need to grin and bear it and create a regular
draw widget for my ROI selection?

Thanks.
