-----------------------------------------------------------------------------

The kernel of the package is a PostScript program, PS_CONV.PS, for converting
one-page PostScript files into EPS (encapsulated PostScript) files readable
by CorelDRAW!(R), Adobe Illustrator(TM) and Fontographer(R). The current
version is to be used with the Ghostscript interpreter.

The main features of the current verion of the converter are as follows:

1) If a multi-page document is supplied, only the first page is processed.
2) Bitmaps are ignored.
3) Fonts are always converted to curves (for Ghostscript ver. < 3 outlines
   of the Adobe Type 1 fonts are approximated by polygons).
4) If the size of a converted object differs essentially from A4 page,
   an internal parameter of PS_CONV, SCALE (by default SCALE=10),
   may require manual tuning. For larger pictures SCALE should be smaller,
   otherwise a `numeric exeption' error may occur; for tiny pictures it
   can be enlarged. Its value can be passed, e.g., in a command line:
       ...  -dSCALE=100 ...
5) So far PS_CONV was tested only with Ghostscript interpreter

-----------------------------------------------------------------------------

The package consists of the following files:

   0PS_CONV.DOC this file
   PS_CONV.PS   the ``engine''
   GC.BAT       sample DOS batch file (making use of GS386);
                to be adjusted to a particular installation
   GC.PAR       parameters for Ghostscript for the converting session
   GC_HEAD.PS   a header, prepended to the result of the conversion
   GC_TAIL.PS   a trailer, appended to the result of the conversion

Additionally, SHOWPAGE.PS file is referred to. It belongs to the standard
Ghostscript distribution.

LOCATION OF FILES (DOS)

It is assumed that all the package is placed in the directory C:\PS_CONV.
If another destination place is required, the following files should be
adjusted:

    GC.BAT
    GC.PAR

Ghostscript interpreter is assumed to be in a directory specified by the
DOS environment variable PATH.
