ps2epsi - generate conforming Encapsulated PostScript
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 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.
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 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.
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.
