!!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 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.
!!USAGE


On Unix systems invoke __ps2epsi__ like
this:


__ps2epsi__ ''infile.ps'' [[ ''outfile.epsi''
]


where


__ps2epsi__ ''infile.ps outfile.epi''


where
!!LIMITATIONS


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.
!!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.
