Graphics2D.drawImage() and clipping region

I assume that the drawImage() method in the Graphics class is smart
enough not to draw the image outside of the clipping region...

I don't really have to only draw a subImage to get this performance boost
do I?

Thanks.

Clipping is pretty fast. Drawing a smaller image would probably be
quicker but then you have the overhead of creating the smaller image. I
don't think it will say you enough to make much difference either way.
