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  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.
