I have an indirect way of producing "unlimited"
size images of grasp surface and that is to
rewrite the grasp file as input for a raytracer
such as Povray. The surface can then be rendered
and output as an RGB image (MUCH smaller than a
ps file !).
I use our Molecular Graphics program PREPI
( http://www.icnet.uk/bmm/PREPI) to read
the grasp surface, set transparency etc and then
output for Povray.
If this program is of anyuse to you let
me know and I can send you download details.
