Searching around, I found the reason should be related with write performances, which seem to be less compromised with large bitmap chunks. I've no problem with that, but is it possible to set the bitmap chunk to the minimum size, without trying all the possible dimensions? Thanks a lot in advance, bye, -- piergiorgio
