As a complement to the previous question.
Concerning the IDL xroi tool, how can I draw several polygons for a
same class ?
For example, polygons 1-3 correspond to class 1, polygons 4-7 correspnd
to class 2, etc.

I managed to do it by calling xroi function n times for n classes. This
implies that the xroi tool is also closed n times, which is not nice.
Thanks

François.
