Michael (others), as you have some experience with gs, can you tell me  
if it is possible for gs to use the bounding box to crop the image.  
Thus producing a bitmap whose size is that of the bounding box?

For example. if I have an eps-file whose bounding box is 6.4x4.8  
inches, and the resolution is set to 100, how do I ensure I get a  
640x480 bitmap?

The reason I ask is that gnuplot includes an extra 50pt border around  
the image. Thus a 6.4x4.8 inch bounding box implies a 7.0944x5.4944  
inch page ... and when I've tried using gs in the past, I get a bitmap  
that corresponds to canvas size (not the size of the bounding box).

What would also be great is to use gs to post-process ps files to crop  
the canvas to the size of the bounding box as well.

Thoughts, ideas?
