PSTOTGIF

pstotgif allows to convert Postscript files to a simple vector graphic
format, that can be edited with tgif. Ask archie on where to find tgif.
pstotgif works by redefining the two basic painting operators of
Postscript, stroke and show. Others like fill or image are not supported.
After redefining these operators, the Postscript file that needs to
be converted is processed by GhostScript (gs). So you need to have
Ghostscript in order to use this program.
pstotgif uses a postprocessor to actually build the input file for tgif.
This is a small lex-program (maketgif). To build it, just type make.
Edit the pstotgif script and change LIB according to your local 
environment.

The output of gs that is piped to maketgif is similar to PostScript (moveto
lineto, show, ...). This is because I once needed to generate a simple
(using only basic operators) PostScript file from a complex one. 

A cleaner approach to all this would be to implement a new device 
driver in GhostScript. This could either dump tgif input directly or
(better) dump the picture as a simple (see above) PostScript file
which can be converted to tgif or other graphic editors by a postprocessor.
If anybody does this or has already done, please let me (glunz@ztivax.zfe.siemens.de) know.


There is one test included. To run it type `make test'

Usage :

pstotgif [-t] [-m number] files

Options:
-t : dont make polygons from text. This however does not take into
     account the current font. So any text will be written horizontally
     with a standard font.
-m factor:
     magnify by a factor. 

pstotgif writes the output to <inputfile>.obj so it can be read into tgif.
