Hi Andrea,
something happened to my inbox that purged your mail...
I hope the title is enough to keep the thread going.
Here is the code that should be testable. It loads some shapes and the
tiff. Right now I'm not sure if I'm allowed to attach the file, so I put
it inline. I'm a bit on a run.
Ciao and thanks,
Andrea
