<h2><a name="Overview"></a>Overview</h2>

<p>
<code>ps2epsi</code> 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
<a href="http://partners.adobe.com/public/developer/en/ps/5002.EPSF_Spec.pdf" 
class="offsite">Encapsulated PostScript</a>
(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.

<h2><a name="Framemaker"></a>Framemaker can use EPSI</h2>

<p>
The <a href="http://www.adobe.com/products/framemaker/main.html"
class="offsite">Adobe Framemaker</a> DTP system is one application which 
understands EPSI files, and <code>ps2epsi</code> 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 <code>ps2epsi</code>, although this has not been 
tested.

<hr>

<h2><a name="Usage"></a>Usage</h2>

<h3><a name="MSDOS_usage"></a>MS-DOS</h3>

<p>
Using the supplied batch file <code>ps2epsi.bat</code>, the command is

<blockquote>
<code>ps2epsi</code> <b><em>infile.ps</em></b> <b><em>outfile.epi</em></b>
</blockquote>

<p>
where <b><em>infile.ps</em></b> is the original PostScript file, and
<b><em>outfile.epi</em></b> is the output EPSI file to be created.

<h3><a name="Unix_usage"></a>Unix</h3>

<p>
Using the supplied shell script <code>ps2epsi</code>, the command is

<blockquote>
<code>ps2epsi</code> <b><em>infile.ps</em></b> <b><em>[outfile.epsi]</em></b>
</blockquote>

<p>
where <b><em>infile.ps</em></b> is the input file and
<b><em>outfile.epsi</em></b> is the output EPSI file to be created. If the
output filename is omitted, <code>ps2epsi</code> generates one from the
input filename; and any standard extension (<code>.ps</code>,
<code>.cps</code>, <code>.eps</code> or <code>.epsf</code>) of the
input file is replaced in the output file with the extension
<code>.epsi</code>.

<hr>

<h2><a name="Limitations"></a>Limitations</h2>

<p>
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.  <code>ps2epsi</code> 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.
