pstricks: PostScript error: undefined in NodeScale

[chrille69]

Hello,

i get the following error, if i try to compile the pstricks-command \pcline:

~/tmp$ dvisvgm -n herleitung-zeitdehnung-aus-doppler.dvi 
pre-processing DVI file (format version 2)
processing page 1
  PostScript error: undefined in NodeScale
  Operand stack:
      --nostringval--  false  N@@@A  10  --nostringval--

If you comment out the \pcline-lines, it work's.

Minimal example:

\documentclass{article}

\usepackage{newcent}
\usepackage{helvet}
\usepackage[german,ngerman]{babel}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage[dvipsnames]{pstricks}
\usepackage{pst-all}
\usepackage{pst-math}
\usepackage{pst-eucl}
\usepackage{pstricks-add}
\usepackage[intlimits]{amsmath}
\usepackage{amssymb}

\section*{Herleitung Zeitdehnung}
\subsection*{Variante I: Lichtuhr}
In einer Lichtuhr wird ein Photon zwischen zwei Spiegeln mit
Lichtgeschwindigkeit $c$ hin und her reflektiert. Sie bewegt sich quer zur
Spiegelachse mit der Geschwindigkeit $v$. Um welchen Faktor vergrößert sich
die Periodendauer der Lichtuhr?

Not reproducible with dvisvgm 3.0.3 (x86_64-apple-darwin18.7.0) here. Was your step to generate .dvi error free?

[mgieseki]

I can't reproduce the error with dvisvgm 3.1.2 and GS 9.55.0 either. Could you convert the DVI file with dvips and does Ghostscript display the generated PS file correctly?

[chrille69]

Which PS file? I execute

latex file.tex
dvisvgm -n file.dvi

There is no PS file in the working directory. latex produces no errors.

[mgieseki]

As mentioned, please convert the DVI file with dvips instead of dvisvgm and run Ghostscript with it afterwards:

dvips file.dvi
gs file.ps

Does GS produce any error messages here?

[chrille69]

OK. I moved to another computer with a fresh texlive installation and all went fine. There is an error in my environment. Sorry for the trouble.

[mgieseki]

No problem. Glad to hear, you could convert the file after all.

NodeScale is a PostScript procedure defined in TeX macro \tx@NewNode, which is then provided in pst-node.tex.

@chrille69 You may want to check the loaded version (and perhaps also location) of pst-node package.
