I suspect that what you're doing is generating a new image sized to fit the
amount of graphics area available. PostScript files contain an enormous number
of pixels that you can write to. It's like having a 24130x17780 monitor to
play around with.

The way to get around this is to use the scalable pixel feature of PostScript.
This is done by using the XSIZE and YSIZE keywords with the TV or TVSCL
command.
