PS2EPSI(1) Ghostscript Tools PS2EPSI(1)NAMEps2epsi - generate conforming Encapsulated PostScript
SYNOPSISps2epsi infile.ps [ outfile.epsi ] (Unix)
ps2epsi infile.ps [ outfile.epi ] (DOS)
DESCRIPTIONps2epsi 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 dis
played 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 dis
played quality is often not very good (e.g., low resolu
tion, no colours), but the final printed version uses the
real PostScript, and thus has the normal PostScript qual
ity.
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 omit
ted, 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.
LIMITATIONS
Not every PostScript file can be encapsulated success
fully, because there are restrictions on what PostScript
constructs a correct encapsulated file may contain.
ps2epsi does a little extra work to try to help encapsula
tion, 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.
COMPATIBILITY
The Framemaker DTP system is one application which under
stands 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.
