Hi Norbert,

But this may not be a desirable fix.

If we use getNum() instead of getInt() in pdftoepdf.cc<http://pdftoepdf.cc>,
tryplot.pdf is created successfully even if we use poppler.
But I don't know the change is harmless or not.
See an attached pdftoepdf.cc.diff.

Surely it is the right thing to be doing.
The PDF spec says  StemV  is a  number  so doesn’t require an  integer .

XHeight

(Optional) The font’s x height: the vertical coordinate of the top of flat nonascending lowercase letters (like the letter x), measured from the baseline, in fonts that have Latin characters. Default value: 0.
