Hi Jason,
Thanks for the info Jason. Sometimes I can't see the wood for the trees and
that is where the newsgroup comes to the rescue!
After looking through the IDL documentation, somehow I managed to miss
LABEL_REGION. This is exactly what I am looking for. I have already
binarised the data by this point so the function does what I need.
However, the new routine you mention does sound interesting and so I will
have a look at it.
Thanks for the info.
Cheers
Dave Brennan
