ps2epsi infile.ps [ outfile.epsi ] (Unix)
ps2epsi infile.ps [ outfile.epi ] (DOS)
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 pro-
grams) 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.
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.
Not every PostScript file can be encapsulated successfully, because
there are restrictions on what PostScript constructs a correct encapsu-
lated 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
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.
