Hi Vladimir,

I would use DisplayImpl.getImage() to get a BufferedImage.
But in case the resoultion will be determined by the size
of the JPanel for the DisplayImpl. For Java2D, you can
create an offscreen DisplayImplJ2D with a large image size.
For Java3D, we have to wait for ofscreen rendering in
version 1.2.1 (we cannot use version 1.2 because it throws
ArrayBoundsExceptions which crash VisAD applications).

Cheers,
Bill
