Re: [Matplotlib-users] LaTeX, eps, ghostscript, and the like

[Ryan K. <rya...@gm...>]

Hey Robert,

I think this is a great idea.  I am using the usetex option on my
system with great success and I would love to help others create these
beautiful plots with gorgeous Latex fonts.

The process depends on a few outside tools right now and that is where
I would guess the problem is.  I am using the xpdf option for
distiller option:
ps.usedistiller   : xpdf

Darren may have a better idea, but my suggestion would be to go
through each of the steps in the figure generation process yourself
and see if one particular tool or setting is causing your font
ugliness.  If you wanted to try this approach, go into
python-root/site-packages/matplotlib/backends/backend_ps.py and put a
pdb.set_trace() around line 1162, just before this line:

if rcParams['ps.usedistiller'] =3D=3D 'xpdf':

Then, when you call savefig, it will stop with a figure started in
your temp directory (the value of psfile from the pdb prompt will tell
you the exact location).

There will be a ps file and a tex file in that location.  If that ps
file looks bad, you are going to need Darren's help.  If the ps file
looks good, the savefig process is basically going to call ps2pdf,
pdftops, and then epstopdf (assuming you saved with a .eps extension).
 If you can take the ps file from the start of this process and
execute each of these commands in turn, you should be able to see
where things are going wrong.

But, you may not be comfortable with all this, may not want to invest
the time, or Darren may have a better idea.

By the way, your website is linked as a how to on the scipy install
and when I try and go there, I get a access forbidden error.  (I get
the same error if I try to follow the link in your signature
pong.tamu.edu).
