Hello, I've had a strange problem regarding a PyX plot last week. I don't know if it's the fault of PyX, but I want to report the problem anyhow.
When I try to include a PDF created by PyX in a LaTeX document using
\includegraphics, pdflatex aborts.
The PDF is created by this code (the code is attached: plot.py: the output is
also attached: plot.pdf):
1 from pyx import *
2
3 text.set(text.LatexRunner)
4 text.preamble(r"\usepackage{mathabx}")
5
6 c = canvas.canvas()
7 c.text(0,0, r"$\widebar{X}$")
8 c.writePDFfile()
I load the mathabx package, create a canvas and write \widebar{X} to the
canvas. PyX creates a PDF which looks fine to me in several PDF viewers
(okular, evince, xpdf). However, I get the warning:
"We are about to extract font information for the Type 1 font 'TeX-mathx10'
from its pfb file. This is bad practice (and it's slow). You should use an afm
file instead."
If I now try to include this PDF in a LaTeX document (see attachement
text.tex), pdflatex crashes and prints the error:
"<plot.pdf, id=1, 11.07693pt x 10.43765pt> <use plot.pdf> [1{/var/lib/texmf/font
s/map/pdftex/updmap/pdftex.map} <./plot.pdfInternal Error (0): Call to Object
where the object was type 2, not the expected type 1
I've solved my problem by not using \widebar. But I don't know if this is a
problem of mathabx, of PyX or pdflatex. Unfortunately, I don't know how one
can check if a PDF file is valid.
I use PyX 0.14 and pdfTeX 3.14159265-2.6-1.40.15 (TeX Live 2015/dev/Debian) on
Debian 8.4.
Best whishes,
