PSBBOX - Changing the BoundingBox

For example, create test PostScript data with suplane and supswigb via

% suplane | supswigb > junk1.eps

where the ``.eps'' extension is chosen as a reminder that this is encapsulated PostScript. Let's say that there is too much white-space surrounding this figure. To fix this problem, we want to change the size of the BoundingBox at the top of the file. For example

% more junk1.eps

shows the dimensions of the BoundingBox

%!PS-Adobe-2.0 EPSF-1.2
%%DocumentFonts:
%%BoundingBox: 13 31 603 746  
...

We could manually edit this, but with psbbox we can type:

% psbbox < junk1.eps llx=40 lly=80 urx=590 ury=730 > junk2.eps
Original:  %%BoundingBox: 13 31 603 746
Updated:   %%BoundingBox: 40 80 590 730 

to yield a smaller BoundingBox, with correspondingly less white space.
