#32 Error: /syntaxerror in /----nostringval----

[Reviczky Ádám János]

When using pstoedit version 3.77 to convert eps or pdf into metapost (-f mpost) I get the following error:

pstoedit: version 3.77 / DLL interface 108 (built: Sep 4 2021 - release build - g++ 11.2.0 - 64-bit) : Copyright (C) 1993 - 2021 Wolfgang Glunz

I have tried it with ghostscript 9.54 and 9.55 but with the same error.
Using pstoedit 3.75 with the above ghostscript versions works just fine.

Please provide me an example input file for the problem.
Thanks

Hi Wolfgang,

I first wanted to try this one: I have downloaded this svg and used inkscape (1.1.1) to save it as an eps - https://www.jpmorgan.com/onyx/images/logo.svg
See attachment logo.eps

[Reviczky Ádám János]

But really it happens with any eps/pdf I save with inkscape, I have attached you a much simpler eps export of a cirlce: see circle.eps

Could it be an issue with how inkscape is exporting the files?

[Reviczky Ádám János]

Then the following commands:

pstoedit -f mpost circle.eps circle.mp

By only downgrading pstoedit from 3.77 to 3.75, the conversion succeeds without any errors and the metapost file is fine.

I am using the following versions from Ubuntu:
ii inkscape 1.1.1-2ubuntu2 amd64 vector-based drawing program
ii ghostscript 9.55.0~~rc1~dfsg-1 amd64 interpreter for the PostScript language and for PDF
ii pstoedit 3.77-1 amd64 PostScript and PDF files to editable vector graphics converter

fixed in 3.78
