You probably have "ps.useafm" set, right? Unfortunately, the stock
Postscript AFM fonts do not have a blackboard style. Setting ps.useafm
to False will use Truetype fonts, and it should work.
Cheers,
Mike

Hello,
I'm getting an error using latex mathbb and exporting to eps. The
following script demonstrates:
from pylab import figure, show
fig = figure()
ax = fig.add_subplot(1, 1, 1)
ax.set_title(r'$\mathbb{R}$')
fig.savefig('mathbb.eps')
On Windows the above gives me a long traceback ending with:
IOError: [Errno 2] No such file or directory:
'q:\\tools\\Python26\\lib\\site-packages\\matplotlib\\mpl-data\\fonts\\afm\\bb.afm'
It works fine if using \mathbf instead of \mathbb or when saving to
pdf etc.
I thought I had this working on Linux, does anyone know if this is a
problem to do with my installation, or maybe an unsupported feature.
Thanks,
Oscar.
