Hi Jae-Joon,
I tried inserting:
mpl.rc('ps', usedistiller=None)
after importing matplotlib, and I get:
$ du -sk *.eps
6204 test_1.eps
34104 test_2.eps
using 'ghostscript' I get:
$ du -sk *.eps
34096 test_1.eps
34104 test_2.eps
and using 'xpdf' raises an exception:
File
"/Users/tom/Library/Python/2.6/site-packages/matplotlib/backends/backend_ps.py",
line 1091, in _print_figure
xpdf_distill(tmpfile, isEPSF, ptype=papertype, bbox=bbox)
File
"/Users/tom/Library/Python/2.6/site-packages/matplotlib/backends/backend_ps.py",
line 1421, in xpdf_distill
image.\nHere is the full report generated by pdftops: \n\n' + fh.read())
RuntimeError: pdftops was not able to process your image.
Here is the full report generated by pdftops:
I don't have a matplotlibrc file, and I am using:
Ghostscript: GPL Ghostscript 9.00 (2010-09-14)
LaTeX: Version 3.1415926-1.40.10 (TeX Live 2009)
and I'm using the latest head from github for matplotlib.
Cheers,
Tom
