10.04.0                                           18 Sept 2024                                        PS2EPSI(1)

       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.

ps2epsi  uses  gs(1) to process a PostScript(tm) file and generate as output a new file which conforms to
       Adobe's EncapsulatedPostScriptInterchange (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.

       ps2epsi.ps    the Ghostscript program which does the work

       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.

ps2epsiinfile.ps [ outfile.epsi ] (Unix)ps2epsiinfile.ps [ outfile.epi ] (DOS)

       On Unix systems invoke ps2epsi like this:

            ps2epsiinfile.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:

            ps2epsiinfile.psoutfile.epi

       where "infile.ps" is the original PostScript file, and "outfile.epi" is the name of the output file.
