[Matplotlib-users] Problem generating pdf file with LaTeX fonts

[Pål G. E. <pa...@gm...>]

Hi

I'm trying to make a plot as a pdf file (or any vector format) with
LaTeX fonts. I can make it output the file using show, but not with
savefig (unless it is raster graphics).
My setup is Fedora 13 64 bit with the latest TexLive:
texlive-2011-0.1.20110227.fc13.x86_64
and matplotlib from svn, revision 8988.

I can run tex_demo.py as it is from
http://matplotlib.sourceforge.net/users/usetex.html
but is I change it such that instead of a png it outputs a pdf, like
the example below, it crashes.
I know there was a post on the mail liste a couple of days ago ( Bug
in `dviread.py'), but I'm not sure if this is the same error, which it
shouldn't be as I'm using the latest svn revision.
Does anyone have the same problem?

The example and debug output are shown below.

Regards

Pål

Example (test.py):
---------------------------
#!/usr/bin/env python

import matplotlib
matplotlib.use('Qt4Agg')

from matplotlib import rc
from numpy import arange, cos, pi
from matplotlib.pyplot import figure, axes, plot, xlabel, ylabel, title, \
    grid, savefig, show


rc('text', usetex=True)
rc('font', family='serif')
figure(1, figsize=(6,4))
ax = axes([0.1, 0.1, 0.8, 0.7])
t = arange(0.0, 1.0+0.01, 0.01)
s = cos(2*2*pi*t)+2
plot(t, s)

xlabel(r'\textbf{time (s)}')
ylabel(r'\textit{voltage (mV)}',fontsize=16)
title(r"\TeX\ is Number $\displaystyle\sum_{n=1}^\infty\frac{-e^{i\pi}}{2^n}$!",
      fontsize=16, color='r')
grid(True)
savefig('tex_demo.pdf')


show()
