I made a wiki entry a while back about how to work around this problem, but it 
looks like someone deleted it in mid-November, and I dont have a backup copy.
My solution requires ghostview and xpdf, which is why we dont include it in 
mpl by default.
You can remove the following block in backend_ps.py, starting around line 
1144:
 command = 'latex -interaction=nonstopmode "%s"' % texfile
 verbose.report(command, 'debug-annoying')
 stdin, stdout, stderr = os.popen3(command)
 verbose.report(stdout.read(), 'debug-annoying')
 verbose.report(stderr.read(), 'helpful')
 command = 'dvips -R -T %fin,%fin -o "%s" "%s"' % (pw, ph, psfile, 
dvifile)
 verbose.report(command, 'debug-annoying')
 stdin, stdout, stderr = os.popen3(command)
 verbose.report(stdout.read(), 'debug-annoying')
 verbose.report(stderr.read(), 'helpful')
 os.remove(epsfile)
 if ext.startswith('.ep'):
 dpi = rcParams['ps.distiller.res']
 if sys.platform == 'win32':
 command = 'gswin32c -dBATCH -dNOPAUSE -dSAFER -r%d \
 -sDEVICE=epswrite -dLanguageLevel=2 -dEPSFitPage \
 -sOutputFile="%s" "%s"'% (dpi, epsfile, psfile)
 else:
 command = 'gs -dBATCH -dNOPAUSE -dSAFER -r%d \
 -sDEVICE=epswrite -dLanguageLevel=2 -dEPSFitPage \
 -sOutputFile="%s" "%s"'% (dpi, epsfile, psfile)
 verbose.report(command, 'debug-annoying')
 stdin, stdout, stderr = os.popen3(command)
 verbose.report(stdout.read(), 'debug-annoying')
 verbose.report(stderr.read(), 'helpful')
 shutil.move(epsfile, outfile)
 else: shutil.move(psfile, outfile)
and replace it with this:
 command = 'latex -interaction=nonstopmode "%s"' % texfile
 verbose.report(command, 'debug-annoying')
 stdin, stdout, stderr = os.popen3(command)
 verbose.report(stdout.read(), 'debug-annoying')
 verbose.report(stderr.read(), 'helpful')
 command = 'dvips -R -T %fin,%fin -o "%s" "%s"' % (pw, ph, psfile, 
dvifile)
 verbose.report(command, 'debug-annoying')
 stdin, stdout, stderr = os.popen3(command)
 verbose.report(stdout.read(), 'debug-annoying')
 verbose.report(stderr.read(), 'helpful')
 os.remove(epsfile)
 pdffile = tmpname + '.pdf'
 if ext.startswith('.ep'):
 command = 'ps2pdf "%s"'% psfile
 os.system(command)
 command = 'pdftops -level2 "%s" "%s"'% (pdffile, psfile)
 os.system(command)
 os.remove(pdffile)
 command = '/usr/local/bin/ps2eps -l "%s"'% psfile
 stdin, stderr = os.popen4(command)
 verbose.report(stderr.read(), 'helpful')
 command = 'epstopdf "%s"'% epsfile
 os.system(command)
 shutil.move(epsfile, outfile)
 shutil.move(pdffile, basename+'.pdf')
 else:
 command = 'ps2pdf "%s" "%s"'% (psfile, pdffile)
 stdin, stderr = os.popen4(command)
 verbose.report(stderr.read(), 'helpful')
 os.remove(psfile)
 command = 'pdftops -paperw %d -paperh %d -level2 "%s" "%s"'% \
 (int(pw*72), int(ph*72), pdffile, psfile)
 os.system(command)
 shutil.move(psfile, outfile)

hi,
i'm triing to install matplotlib with ubuntu breezy
(amd64). An error occurs with 'python setup.py build' :
gcc -pthread -fno-strict-aliasing -DNDEBUG -g -O3 -Wall
-Wstrict-prototypes -fPIC -Iagg23/include -Isrc -Iswig
-I/usr/include/python2.4 -c src/agg.cxx -o
build/temp.linux-x86_64-2.4/src/agg.o
gcc: installation problem, cannot exec 'cc1plus': No such file or directory
error: command 'gcc' failed with exit status 1
have you any ideas ?
thanks.

When using tex for font rendering I noticed that parts of the text are not
converted to polygons but embedded as bitmaps. That makes the files big again.
Do you now how to avoid that? E.g. using the r'$C_{12}$ will produce two images
for the numbers and a polygon for the 'C'.

There are currently two options: you can either set ps.useafm = True, or you 
can set text.usetex = True in your rc settings. Since you are importing 
figures into latex, I suggest the usetex option. That way, your figure fonts 
can be the same as your text fonts. You'll take a bit of a speed hit with the 
latter option, but in my opinion, its the only way to go for generating plots 
for publication.

Hi,
I'm trying to use matplotlib solely for my plotting needs.
Problem is, the fonts are embedded in each EPS file, and
when I import several plots (I have tens of them...) into a
single Latex, the resulting file is HUGE.
Any suggestions?
Thanks,
Alex
