Thanks Andrea,
this is great news!
In fact now starts to read it, but not without problem.
The geotiff in fact has a world file. It should be a "normal" file
(whatever that could mean).

The geotiff is a "Carta Tecnica Provinciale", which you should probably
know and have dealth with.

PS: another question: the projection is taken by default in lat/long, if I do
not
supply a .prj file with the info in it. Is that the right approach? I've
never seen geotiffs or jpegs with the projection file.
