description
ps2epsi
uses gs(1) to process a PostScript(tm) file
and generate as output a new file which conforms to
Adobe’s Encapsulated PostScript Interchange
(EPSI) format. EPSI is a special form of encapsulated
PostScript (EPS) which adds to the beginning of the file in
the form of PostScript comments a bitmapped version of the
final displayed page. Programs which understand EPSI
(usually word processors or DTP programs) can use this
bitmap to give a preview version on screen of the
PostScript. The displayed quality is often not very good
(e.g., low resolution, no colours), but the final printed
version uses the real PostScript, and thus has the normal
PostScript quality.
compatibility
The Framemaker DTP system is one application which
understands EPSI files, and ps2epsi has been tested on a
number of PostScript diagrams from a variety of sources, using
Framemaker 3.0 on a Sun workstation. Framemaker on other
platforms should be able to use these files, although I have not
been able to test this.

limitations
Not every PostScript file can be encapsulated successfully,
because there are restrictions on what PostScript constructs a
correct encapsulated file may contain. 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, where
the encapsulation does not work because of the content of the
original PostScript file.
usage
On Unix systems invoke ps2epsi like this:
ps2epsi infile.ps [ outfile.epsi ]
where "infile.ps" is the input file and "outfile.epsi" is the
resulting EPSI file. If the output filename is omitted, it is
generated from the input filename. When a standard extension
(".ps", ".cps", ".eps" or ".epsf") is used, it is replaced with
the output extension ".epsi". On DOS systems the command is:
ps2epsi infile.ps outfile.epi
where "infile.ps" is the original PostScript file, and
"outfile.epi" is the name of the output file.
