PVO's ps -> eps summary: (updated 22 aug 90)


Two lines are usually enough to fake the PS -> EPSF conversion

1) Start the postscript file with the line:
                %!PS-Adobe-2.0 EPSF-1.2

2) Include a BoundingBox: line, eg:
                %%BoundingBox: 0 0 504 378

3) For framemaker, IMPORT, do not INCLUDE the fake EPSF file.

This works for all NeXT apps requiring EPSF (including Frame2.0) and 
Frame1.3 on Sun's.  (On the Next, the file is interpreted and you get
to see it!).

To calculate the BB: 

        bbfig by Ned Batchelder sometimes works.
          [rtsg.ee.lbl.gov:dvi2ps.tar.Z]

        distill by Glenn Read usually works.
          [ Adobe fileserver
		To: ps-file-server@adobe.com
		send programs still.ps]

	epsinfo.ps usually works
	  [ Adobe fileserver:
		To: ps-file-server@adobe.com
		send Programs epsfinfo.ps]

        printing the file and measuring with a ruler always works.

        For images:
                Patch fbps to do 1) and 2)  (patch included, below)
                  [nl.cs.cmu.edu:/usr/mlm/ftp/fbm.tar.Z]
 
        For Unix plot(5) graphs:
                Use plot2ps instead of psplot.

==========================================================================
		     [distill & epsinfo.ps do more than BB calculation,
		      they check for "nasty" instructions and throw in
		      the proper meta-comments here and there]
