# mathbb and eps export

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.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.

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

Thanks, Mike.

I've been away from the Windows machine for a couple of days. I did
ps.useafm set and your suggestion solved the problem.

Is there a reason not to use TrueType in all of my figures (since it
wasn't enabled by default)?

Thanks,
Oscar.

The main difference is file size. When ps.useafm is True, the fonts don't have to be embedded because it uses fonts that are required to be available with every Postscript interpreter. When it is False, the fonts have to be included as part of the file, resulting in larger file sizes.
