LEARN ABOUT OPENSOLARIS
ps2epsi
PS2EPSI(1) Ghostscript Tools PS2EPSI(1)
NAME
ps2epsi - generate conforming Encapsulated PostScript
SYNOPSIS
ps2epsi infile.ps [ outfile.epsi ] (Unix)
ps2epsi infile.ps [ outfile.epi ] (DOS)
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 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.
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.
LIMITATIONS
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 PostScript file.
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.
