Yes, of course. The easy way to do get a bitmap is to preview your 
file on screen and then screendump it to a rasterfile...

... probably you want to create bitmaps that are larger than your screen. You
can still use the the NeWS server to do this.

You need to give xnews a PostScript procedure that is executed instead of 
startup.ps that creates a canvas the size that you need for printing, scales
and images the code, and writecanvas'es the bitimage to a file. This 
is all done without calling startup.ps which starts the server on 
your console.

The PostScript procedure is not hard to write for someone who has
some experience with NeWS, finding the option that gets your code 
executed instead of startup.ps is the tricky part, Sun does not document it 
and is not very helpful. They do not want you to use their fonts for printing
unless you have paid for NeWSPrint. You only need to render graphics w/o
text, right?

The PostScript interpreter used in NeWSPrint is the standard X11/NeWS server.
