- OVERVIEW:
-
- ps2epsi is a utility, based on Ghostscript, which takes an input postscript
- file and generates a new output file which conforms to Adobe's 'Encapsulated
- Postscript Interchange' or EPSI format. This is a special form of encapsulated
- postscript (EPS) which adds a bitmap version of the final displayed page (in
- the form of postscript comments) to the beginning of the file. This bitmap
- can be used by programs which understand EPSI (usually word processors or
- DTP programs) to give a preview version of the postscript on screen. The
- displayed quality is often not very good (eg. low resolution, no colours),
- but the final printed version uses the 'real' postscript, and thus has the
- normal full postscript quality.
-
- FRAMEMAKER:
-
- 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. I believe that Framemaker
- on the other platforms should also be able to use these files, although I
- have not been able to test this.
-
- FILES:
-
- ps2epsi.doc - this file
- ps2epsi.bat - MSDOS batch file
- ps2epsi - Unix shell script
- ps2epsi.ps - the Ghostscript program which does the work
-
- MSDOS USAGE:
-
- Using the supplied batch file, the command is simply:
-
- ps2epsi infile.ps outfile.epi
-
- where infile.ps is the original postscript file, and outfile.epi is the
- name of the output file.
-
- UNIX USAGE:
-
- Using the supplied shell script, the command is:
-
- ps2epsi infile.ps [outfile.epsi]
-
- where infile.ps is the input file and outfile.epsi is the output EPSI
- file. If the output filename is omitted, it will be generated from the
- input filename - if a standard extension (.ps, .cps, .eps or .epsf) is
- used, this will be replaced with the output extension .epsi .
-
- LIMITATIONS:
-
- Successful encapsulation of arbitrary postscript files cannot be guaranteed,
- as there are certain restrictions in what is permitted in a postscript file
- for it to be properly encapsulated. 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 bound to be cases, however, where the
- encapsulation will not work, because of the content of the original postscript
- file.
