Most current graphical editors (e.g., CorelDraw, Illustrator) 
import the postscript output from the Perple_X programs. The
following notes on Ghostscript may be useful for older 
applications. The program MacGS referred to here is the 
MacIntosh implementation of Ghostscript. 

You can use Ghostscript in two ways:

1) To view the output from PSVDRAW, start Ghostscript, click 
on the "Graphics" window, then open the ps file with the 
"pull-down" menu under MacGS. If you attempt to save or 
print an image  using this utility you will get a LOW quality 
raster image.

2) To convert the PSVDRAW encapsulated PostScript to Adobe
Illustrator format (i.e., something that you can edit in 
Adobe Illustrator 5.0, or Coreldraw). Do one of the following:

  i) On Unix or Apple:

  Open the file ps2ai.ps (as described above) and then open 
  the ps file from PSVDRAW Ghostscript then automatically 
  creates the file ps2ai.out.ps, which contains Adobe 
  format PostScript. One problem with this procedure 
  is that the file type and creator for ps2ai.out.ps 
  are not specified by Ghostscript. Consequently, 
  ps2ai.out.ps is invisible to most Mac applications, one 
  way to get around this is by using ResEdit to change the 
  file type to TEXT and the creator to whatever you want 
  (e.g., just blanks). There are probably much better 
  ways of doing all this, but you'll have to read the 
  instructions to work them out.

  ii) On Unix issue the command:

  gs -q -dNODISPLAY ps2ai.ps file.ps > file.aips

  where file.ps is the postscript file generated by 
  PSVDRAW, and file.aips is the adobe/corel editable
  file to be created.

P.S. Ghostscript is in MacGS 2.5.2 Runtime. The filter
ps2ai.ps is also in my graphics directory.
