[Matplotlib-users] latex output problem
Hi all, I have absolutely no idea what the problem is. I'm running the actual enthought python version (on WinXP) which includes matplotlib version 0.87.3. The conversion of the dvi file to png does not work: dvipng -bg Transparent -D "200" -T tight -o "C:\temp\temp\.matplotlib\tex.cache\6ded4018a133b00dd5abd9e27ca15efa.png" "C:\temp\temp\.matplotlib\tex.cache\a7b7bb1f22dc4f78602fb90e430bed74.dvi" ... RuntimeError: dvipng was not able to process the flowing file: C:\temp\temp\.matplotlib\tex.cache\a7b7bb1f22dc4f78602fb90e430bed74.dvi Here is the full report generated by dvipng: This is dvipng 1.6 Copyright 2002-2005 Jan-Ake Larsson dvipng: Fatal error, bad -D parameter The path to the dvi file is correct. The strange thing is, that this commands works when I paste it into the windows command line! I hope someone can help me. Regards Wolfgang - Using Tomcat but need to do more?

I don't understand why the 200 is being quoted in the -D flag, etc
-D "200"
The relavent bit of code in matplotlib.texmanager reads
command = self.get_shell_cmd('cd "%s"' % self.texcache,
'dvipng -bg Transparent -D %s -T tight -o \
"%s" "%s" > "%s"'%(dpi, os.path.split(pngfile)[-1],
os.path.split(dvifile)[-1], outfile))
WOlfgang, try playing around with this code in
site-packages/matplotlib/texmanager.py (in the make_png function).
Does this help
command = self.get_shell_cmd('cd "%s"' % self.texcache,
'dvipng -bg Transparent -D %d -T tight -o \
"%s" "%s" > "%s"'%(int(dpi),
os.path.split(pngfile)[-1],

Re: [Matplotlib-users] latex output problem
Hello John,
I had also to remove the quotationmarks from the png/dvi Filename
command = 'dvipng -bg Transparent -D %s -T tight -o %s %s'%\
(dpi, pngfile, dvifile)
Now it works fine! Thanks for the quick reply.

Thanks for the quick reply. But it's still not clear where the quotemarks on the 200 came from in the first place, as they ere not in the src code, at least in my version.

Re: [Matplotlib-users] wxmsw26uh_vc.dll and matplotlib 0.87
Hello Charlie,
I tried the solution you suggested below to get py2exe working and get rid of
the "no such file wxmsw26uh_vc.dll" message when trying to run the compiled .exe
1. I removed the _wxagg.pyd file from matplotlib/backends (although I was loathe
to do so as my guess is that this will make plotting slower?)
2. I removed the exclusion on the wxmsw26uh_vc.dll in the setup file
Now I can compile to an .exe but the application starts briefly, but stops and
closes the output window before I can see anything. It doesn't write anything to
the .log file.
I'm running XP, Python 2.4, wxPython 2.6.3.3-py4 and MPL 87.5
Has anybody else tried this solution and got it to work?
Thanks for any help you can provide.
- Daniel
P.S. If it's relevant, my setup.py is below...

I look forward to the unification, but unfortunately I don't think it will help with this crash (unless the very fact that the numarray and/or Numeric are installed but not loaded can cause problems). I see the crash even with this trivial script: $ python >>> from pylab import * >>> plot([1,2,3,4]) >>> show() boom! matplotlib 0.87.5 crashes with ~/.matplotlib/matplotlibrc set to use numarray (1.5.1), Numeric or numpy (1.0b5). > > I don't have wx or gtk installed, so no easy way to test those backends. > > if you install the mpkg on pythonmac.org/packages, wx should work. > that's pretty easy. Fair enough. I installed wxPython (2.6) and the above scripts works fine (as long as interactive is false). > > It does not crash with plain old Agg (but of course I don't see any plot). > > Does it save a png successfully? I can try this if you think it will help. It appears to be a lot more work than just slapping up a plot using pylab so I've not tried it yet. I also failed to build matplotlib from source. I had all the prerequisites in /usr/local (and I reinstalled freetype 2.2.1 to be sure, since the version shown in /usr/local/lib has no resemblance to the source version). During the build I see these warnings (but no errors): /usr/bin/ld: for architecture i386 /usr/bin/ld: warning /usr/local/lib/libpng.dylib cputype (18, architecture ppc) does not match cputype (7) for specified -arch flag: i386 (file not loaded) and after installation, importation of pylab fails as follows: >>> from pylab import * Traceback (most recent call last): File "", line 1, in ?
