[Matplotlib-users] eps font finding problem on WinXP (?)

[Gary P. <pa...@in...>]

I've poked around the docs and archives, for a clue to this, but if it's
there I didn't recognize it.

version:  0.62
WinXP
default backend:  TkAgg
interactive  (with ipython)

On computer A I have version 0.54 installed.  There I can create a plot and
say
savefig('plot.eps')
and get a good eps file.

On computer B I have version 0.62 installed.  There I can create a plot and
say
savefig('plot.eps')
with different results: ghostscript chokes.

In the case of computer A, the eps file contains
/NewCenturySchlbk-Roman findfont
while in the case of computer B, the file contains instead
/BitstreamVeraSerif-Roman findfont

both have TTFPATH=c:\windows\fonts

it's *possible* (I don't remember exactly) that I installed 0.61 from a
windows installer, and 0.54 from setup.py.

afaik, the .matplotlibrc are the same (at least in the font section)
computer B contains a file .ttffile.cache, while computer A does not have
this file
Removing it from B doesn't make any difference.

any idea ... ?

Hi Gary, just to make sure we're clear.  The last version of
matplotlib released was 0.61.0.  Is this what you mean, or are you
using CVS?

There is a known bug in the ps backend on win32 that was discussed
here a couple of weeks ago.  Fortunately, it has a trivial fix.  In
site-packages/matplotlib/backends/backend_ps.py, in the encodeTTFasPS
function, replace the line

    font = file(fontfile)

with

    font = file(fontfile, 'rb')

Windows cares a lot about that binary flag.

Please let me know if this cures what ails you, because we are getting
ready to release the next matplotlib version and I hate to release
code with known bugs.

Thanks!

0.61.0   (my typo)

That was it.  Problem solved.

I remember that thread now.  It didn't sink in at the time.   Thanks,  Gary
