Thread: [matplotlib-devel] stixsans + mathtext.default : regular

Mike (or anyone else),

I've been using the following combination of settings:

mathtext.fontset : stixsans
mathtext.default : regular

I've noticed this crashes when I run scripts that include mathtext with
\rm{} commands.  In fact, I get a massive traceback with this configuration
when running the mathtext_examples.py.  Here's the last few lines:

 File
"/home/rmay/.local/lib64/python2.5/site-packages/matplotlib/pyparsing.py",
line 950, in _parseNoCache
    tokens = fn( instring, tokensStart, retTokens )
  File
"/home/rmay/.local/lib64/python2.5/site-packages/matplotlib/mathtext.py",
line 2381, in symbol
    return [Hlist( [self._make_space(0.2),
  File
"/home/rmay/.local/lib64/python2.5/site-packages/matplotlib/mathtext.py",
line 2351, in _make_space
    state.font, rcParams['mathtext.default'], 'm', state.fontsize,
state.dpi)
  File
"/home/rmay/.local/lib64/python2.5/site-packages/matplotlib/mathtext.py",
line 446, in get_metrics
    info = self._get_info(font, font_class, sym, fontsize, dpi)
  File
"/home/rmay/.local/lib64/python2.5/site-packages/matplotlib/mathtext.py",
line 579, in _get_info
    self._get_glyph(fontname, font_class, sym, fontsize)
  File
"/home/rmay/.local/lib64/python2.5/site-packages/matplotlib/mathtext.py",
line 812, in _get_glyph
    fontname, font_class, uniindex)
  File
"/home/rmay/.local/lib64/python2.5/site-packages/matplotlib/mathtext.py",
line 919, in _map_virtual_font
    mapping = mapping[font_class]
KeyError: 'regular'

Is this a supported configuration?  I know that I personally like the look
of the text with these two settings.  Thoughts?

The 'regular' font stuff just isn't very well tested yet.  I think I 
have a fix in SVN now.

I was rounding where I should have been truncating.  I think this is 
fixed now in SVN.

That fixes it for me.  Thanks a lot for the quick fixes!
