Hi and thanks, sounded almost too good to be true!
Alas, I can't get this to work and the javadocs aren't exactly very verbose,
either.
I wrapped my viewer (a JPanel) in that AffinePanel and added a slider to my
control panel (which is NOT part of the above viewer), so that I can control
the zoom factor. In the slider's event listener I modify the zoom factor and
then call the AffinePanel's scale(...)-method to change the zoom factor.
But strange enough, whenever I move the slider (i.e. whenever I call the
scale-method), I get the following exception and my app hangs:
Exception in thread "AWT-EventQueue-1" java.lang.InternalError: Win32OSSD_Lock

Any idea, what I might be missing to get this going?
