refreshing a scrolledwindow

Thanks to the valuable comments I received on this list I finally
managed to make it work, I just have to smash the last imperfection :slight_smile:
I can open a TIFF file and use it inside a bufferedDC, but for some
reason I have to scroll the window to display the content of the file,
so I'm asking for help again ...
The code and an example TIF is in attachement, probably I need to
refresh the dc or something like that, but I'm not able to find anything
on the docs by now.

TIA,
