Cay anyone can provide some guidance on using system-installed fonts on
Mac OS X?
I'm using the PDF backend in matplotlib 0.91.2 on 10.5 (leopard)'s native
python 2.5 installed with easy_install. Things seem to be working well and
with matplotlib.font_manager.OSXInstalledFonts() I can see that it seems
to know what fonts I have on my system. I can even get it to find some of
these fonts however any attempts to use them results in errors when
writing out the figure (I've included some stack traces below).
Are there reasons to think another backend would work if PDF fails? Also,
I'd be interested in an easy way to take a given font file and know
whether it is of a type supported by MPL and what name I should give to
MPL to find and use it.
