Yeah, well, that's why the industry average is about
five good lines of code a day. :-)

Well, that's very true, but, the problem with this is that I seem to
find myself doing this very scratching of the head just about every
day! :( (and the really depressing thing is that I'm only half-joking

Conversely, you know you have found the right solution
when the change takes two minutes, propagates through
*all* your objects, and causes you to scare the bejesus
out of the dog when you scream "I LOVE OBJECTS!!!"

Well, the wonderful thing about objects is that there are
always multiple ways to do the same thing. Of course, some ways
are better than others. The rule of thumb I use is if an
hour has passed and I am still sitting there scratching my
head and muttering "What the hell...this is getting WAY
complicated!" then there is probably a better way. :-)

David

David,
Yep, I tried it and it worked perfectly. I wish I'd posted about this
a lot sooner...before I decided to try seeing what the group said
about my problem, I was about 90% of the way through some other sloppy
solution that I won't go into :) Thanks for making life easier though
- which you did do even though I had almost done it some other way.

Yes, that is what I mean.

Well, I chose the definition judiciously so this should
have happened automatically if you followed my explicit
directions. :-)

No problem. Did you try it? It worked perfectly for me.

David,
Thanks for your help. I must be more tired than I thought, though,
b/c i'm not sure i get what you're saying (sorry...i'm still pretty
much a newbie here in a lot of ways). When you say you'd define
another keyword for XROI, do you mean you'd modify the XROI routines
themselves (the xroi.pro file)? And if so, don't you have to more
than modifiy just the definition so that the routine will handle
giving you back the OWINDOW object?
Sorry if this was something I should've already known. Thanks again
for your help.
Jeff

Here is what I would do. I would define another keyword
for XROI, named OWINDOW. I would define it like this:
XROI, $
..., $
OWINDOW=oWindow, $
...
Then, I would call XROI like this:
IDL> XROI, myimagem OWINDOW=win
After I had drawn my ROI's and before I opened any other
windows, I would do this:
IDL> win -> GetProperty, Image_Data=theImage
IDL> Write_Tiff, 'myroiimage.tif', Reverse(theImage,3)
There you go. :-)
Cheers,
David
