David,

This may be a really silly question on my part, but does IDL comes with an object tool
like your XROI? (I'm assuing CW_DEFROI ain't it)

If not, when are RSI going to start shipping IDL with all your tools as part of a standard
library? (aka toolkit in matlab-speak). Seems to me that these sorts of
ready-to-use-out-of-the-box tools should be part of IDL regular (maybe that's what iTools
stuff is supposed to do..I dunno). It's just that, with the flurry of ROI questions in the
past week, I realised that a lot of stuff that people want to do wouldn't be easily
do-able without your tools (I don't do a lot of image processing and what not, maybe
that's why the realisation took so long...)

Anyway, without sounding like too much of a brown noser, I just wanted to say goodonya.
