This message will serve a couple of purposes. First the 2D team is
now back in offices and reading their email (and this list) again
after having moved offices to a new campus. Second, the beta 2 release
of JDK 1.4 was published just before we moved and we did not get a chance
to mention a couple of caveats about that release before we had to pack
up our old offices.
If you visit the 2D web site:
http://java.sun.com/products/java-media/2D/
you will see a white paper which describes some of the performance
improvements in 1.4 and some important caveats.
In particular, even though we have "fixed" the image scaling performance
problem there was a problem with our fix that required some drastic
action before we shipped the beta 2 release such that most modern
PCs with high performance graphics cards will actually see a huge
drop in image scaling performance in many cases. This can be fixed
by either setting ddoffscreen=false to disable VRAM surfaces and let
the new software algorithms do their optimal thing or by setting
ddscale=true and letting the experimental hardware scaling loops
do their *really* quick thing. Both options and how to set them
are detailed in the white paper so it is worth a read to see how
and when you might run into problems and some workarounds.
This image scaling regression will be fixed by FCS...
