--- Start of Idrisi List message
In fact, I wrote a new group module allowing to "group" large maps with
group number larger than 32000 : 1) It ignores the background value 2) it
uses rounded real to name the found groups. As a plus, as it is a 32-bits
module, it runs faster than the original Group operator of Idrisi...
Let me know if you are interested.
