Re: [Matplotlib-users] [CJK] can create png but not eps

[David <ld...@gm...>]

Dear Michael,

thanks for your input. So far, though, no luck.

I have deleted "SimHei" in matplotlibrc, and I can then continue 
generating CJK characters. The png is generated, the eps is not. Thus, 
no change. The error output is also the same:

RuntimeError: Face has no glyph names
WARNING: Failure executing file: <dea.py>

I have tried

  import matplotlib
  matplotlib.use('GtkCairo')

as you suggested, but they had no effect whatsoever. Even the error 
output is the same.

I attach my code, maybe that gives a hint.

Note: in line 327 and 328 of the matplotlibrc I have added

ps.fonttype=42
pdf.fonttype=42

whereas I have uncommented

pdf.fonttype	: 3

Any ideas? I would most welcome any hint and suggestion!

Many thanks,

David
