Greetings,

I am using gEDA gschem 1.8.2 (g875406c) and GhostScript 9.26 on 
Slackware Linux 14.2.

What I am trying to do is export my gschem drawing and import it into 
QCAD. I "printed" the drawing to a PostScript file and tried to use 
pstoedit to convert the PostScript file to a DXF file which QCAD will 
import. This has worked well on a PCB eps exported file. In fact I 
tested it today and it still is working. However, pstoedit seems to 
fail. Rather, it seems to be GhostScript that is failing when it 
encounters a "findfont" name in the gschem PostScript file. I am pretty 
sure this process worked for me in the past (years ago) when I had to 
convert a gschem drawing to a DXF file. Something since then has changed 
and I expect that to have been GhostScript, since it has been updated 
twice since I may have used it. The gs versions I have had installed in 
the past are 9.19, 9.25, and now 9.26. According to my research on 
pstoedit, the pstoedit failures started with the 9.2x series, if that helps.

My pstoedit command is:

     pstoedit -f dxf -xscale 1.0 -yscale 1.0  gschem_file_name.ps 
gschem_file_name.ps.dxf

Here is the output of pstoedit:

------

I then converted the gschem ps file to eps with eps2eps and then used 
pstoedit on it, with the following response:

It looks like maybe "findfont" was a PostScript key word or function at 
one time, but now GhostScript is no longer supporting it. I am not a 
Postscript guru.

Two questions:

 1. Is this problem known and is there a work-around?

 2. Is there another gschem process I can use to get a workable
    PostScript, Encapsulated PostScript, or DXF-directly output file
    which I can import into QCAD?

Thanks.

Girvin Herr
