Overview
The Adobe Framemaker DTP system is one application which
understands EPSI files, and
Using the supplied batch file
where infile.ps is the original PostScript file, and
outfile.epi is the output EPSI file to be created.
Using the supplied shell script
where infile.ps is the input file and
outfile.epsi is the output EPSI file to be created. If the
output filename is omitted,
Not all PostScript files can be encapsulated, because there are
restrictions in what is permitted in a PostScript file for it to be
properly encapsulated.

Ghostscript version 9.56.1, 4 April 2022
ps2epsi is a utility based on Ghostscript, which takes as
input a PostScript file and generates as output a new file which conforms
to Adobe's Encapsulated PostScript Interchange (EPSI) format, a special
form of
Encapsulated PostScript
(EPS) which adds to the beginning of the file, as PostScript comments, a
low-resolution monochrome bitmap image of the final displayed page.
Programs which understand EPSI can use this bitmap as a preview on screen
of the full PostScript page. The displayed quality is often not very good,
but the final printed version uses the "real" PostScript, and thus has the
normal full PostScript quality.
ps2epsi has been tested using
Framemaker 3.0 on a Sun workstation with a number of PostScript diagrams
from a variety of sources. Framemaker on other platforms may also be able
to use files made with ps2epsi, although this has not been
tested.
Usage
MS-DOS
ps2epsi.bat, the command is
ps2epsi infile.ps outfile.epi
Unix
ps2epsi, the command is
ps2epsi infile.ps [outfile.epsi]
ps2epsi generates one from the
input filename; and any standard extension (.ps,
.cps, .eps or .epsf) of the
input file is replaced in the output file with the extension
.epsi.
Limitations
ps2epsi does a little extra work to
try to help encapsulation, and it automatically calculates the bounding box
required for all encapsulated PostScript files, so most of the time it does
a pretty good job. There are certain to be cases, however, when
encapsulation fails because of the nature of the original PostScript file.
