The image.pdf_tex documents created with Inkscape's PDF+LaTeX export use this code

  \ifx\svgwidth\undefined%
    \setlength{\unitlength}{293.02998953bp}%
    \ifx\svgscale\undefined%
      \relax%
    \else%
      \setlength{\unitlength}{\unitlength * \real{\svgscale}}%
    \fi%
  \else%
    \setlength{\unitlength}{\svgwidth}%
  \fi%

which makes it sound that instead of the usual

\def\svgwidth{15cm}
\input{image.pdf_tex}

you could do something like

\def\svgscale{0.2}
\input{image.pdf_tex}

However, it gives an error in pdflatex's output:

(.image.pdf_tex
! Undefined control sequence.
<argument> \unitlength * \real 
                               {\svgscale }
l.43 ...nitlength}{\unitlength * \real{\svgscale}}
                                                  %
?

How can I make this work?

The reason is that I want to include to vector graphic subfigures that have different sizes, but at should be displayed at the same scale.

    the package is using calc package syntax so add \usepackage{calc} to your document. – David Carlisle Aug 30 '17 at 21:30
  • Note that changing that one line to \setlength{\unitlength}{\svgscale\unitlength}% seems to work, but since this is an autogenerated document it doesn't feel like the right way? – Laurenz Aug 30 '17 at 21:30
  • @DavidCarlisle yup, that does the trick! If you add this as an answer I can accept it. – Laurenz Aug 30 '17 at 21:32
