I have been following the discussions about getting LaTeX text processing, I have tried it myself, and I have been unsuccessful. I gave gnu-ghostscript, I have tried a number of different rc settings, but nothing seems to work well. PNG output has very poor quality text, EPS output chokes ghostscript, and PS output appears as nothing. I am sure I am doing something stupid. I just don't know which stupid thing it is. Is there a place where all of the important issues are laid out? I would like to see someone who understands all of the important issues start a HOWTO on the scipy Wiki. I would contribute, after I get going.. Short of that, any sort of conglomeration of information would be very helpful.

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).

I would start by clearing your .matplotlib/tex.cache directory. Then set
verbose.level : helpful in your matplotlibrc settings. This will cause mpl to
spit out the important messages that are produced during the calls to latex,
dvips, ghostscript, etc. For the time being, set your ps.usedistiller rc
option to either none or ghostscript. Once you get that working, you can move
on to using xpdf like Ryan suggested.
I dont understand why png output would be bad. Does the text look bad on the
screen as well? What OS are you using, what version of latex, and what
version of dvipng? Try making a very simple latex file, like:
\documentclass[10pt]{article}
\pagestyle{empty}
\begin{document}
Hello, world! $e^{i\pi\theta}$
\end{document}
make a dvi, and then make a png using dvipng. My guess is that the problem is
dvipng, because the text that mpl shows you on screen and in png output comes
straight from dvipng. Incidentally, my png output looks fine, see attached.

Let me know what you found confusing about the existing usetex wiki page at
SciPy, so I can improve it.

I have tried the key utilities by hand (latex & dvipng). I even went
into the tex_cache and processed one of those tex files by hand as
well. This all works for me. In particular, the font rendered in
png is dithered, while in the matplotlib, on my screen and using
savefile, the font is *not* dithered on either the axis or in text
(). The file Darren sent is also nicely dithered. See the attached
zoomed sample of non-dithered text. Oh, so ugly...
I am using Mac OS X 10.4, a recent distribution of teTeX from the i-
Installer (the same as recommended by TeXShop), gnu-gs 8.16, CVS
matplotlib 0.86.2, etc. (I think this is all the relevant info for
now..)
relevant rc stuff:
text.usetex : True # use latex for all text handling. See
ps.papersize : letter # executive, letter, legal, ledger, A0-
A10, B0-B6, C0-C6
ps.useafm : False # use of afm fonts -- breaks mathtext
but results in small files
ps.usedistiller : None # can be: None, ghostscript or xpdf
# Experimental: may
produce smaller files.
# xpdf intended for
production of publication quality files,
# but requires
ghostscript, xpdf and ps2eps
ps.distiller.res : 6000 # dpi

Are you using NumPy, Numeric, or numarray, and what version? What backend, GTKAgg, WXAgg? I'm grasping at straws here, maybe there is a problem with backen_agg's draw_image on your platform or with your configuration, but I can't investigate because I can't reproduce the problem. Also, please try running dvipng -bg Transparent -D dpi -T tight dvifile, replacing dpi with numbers like 60, 80, 100, 140, just to make sure that dvipng is producing scaled images that look correct.

Try hard coding the full path to dvipng from the command line and in
texmanager to make sure you are using the version you think you are.
Also, flush the tex cache.
Find this bit of code in texmanager
vers = self.get_dvipng_version()
#print 'dvipng version', vers
if vers<'1.6':
# hack the alpha channel as described in comment above
alpha = sqrt(1-X[:,:,0])
else:
alpha = X[:,:,-1]
print the dvipng version in texmanager. Also, see which part of the
conditional you are executing, and then manually try forcing both with
if 1:
# hack the alpha channel as described in comment above
alpha = sqrt(1-X[:,:,0])
else:
alpha = X[:,:,-1]
and
if 0:
# hack the alpha channel as described in comment above
alpha = sqrt(1-X[:,:,0])
else:
alpha = X[:,:,-1]
Make sure you flush the tex cache and rerun matplotlib from the shell
(not ipython) with each test.

This seemed to be the problem (perhaps vers<='1.6' is meant). I use

Try editing matplotlib/texmanager.py and replacing the < with <= in
the following code; it should read
if vers<='1.6':
# hack the alpha channel as described in comment above
alpha = sqrt(1-X[:,:,0])
else:
alpha = X[:,:,-1]
also, print the version number and let us know what you have.
Make sure you rm -rf the ~/.matplotlib/tex.cache after reinstalling.

I made the change and that fixed the problem. The output of dvipng -- version is below. Thank you very much. I assume that the fix will be in the cvs version? One more question. Even though I have my rc file set to use type1cm font font.latex.package : type1cm It uses an non latex font for on screen display. The saved version of the plot uses a latex font but the latex font is always serif regardless of the font.family setting.

Hi Robert,
I am working on clearing up the code for cvs, but wanted to double check with
you: what did you have to do to fix the dvipng problem? I ask because I also
have dvipng version 1.6, and dont have any problems with the cvs codebase.
WOuld you send me the output of dvipng -v?

I am using the I-Installer version of teTeX on Mac OS X. I imagine
that many other Mac users might be experiencing similar problems.
Here is what worked for me, with many thanks to Darren for helping me
work through this:
First, using the dvipng 'hack' for dvipng versions less than 1.6
worked to get me PNG output using LaTeX. Also, commenting out line
141 in texmanager:
self._font_preamble = '\n'.join([r'\usepackage{type1cm}',
cmd,
# r'\usepackage[T1]{fontenc}', # The
guilty line
r'\usepackage{textcomp}'])k
allowed me to save EPS files that work very well.
Finally, for those of you interested in editing EPS files in
Illustrator, you need to worry about the absence of the Computer
Modern fonts in Adobe products. This link (really work checking out
if you do scientific graphics on a Mac) explains how to get
everything working for Illustrator CS and CS2:
http://darkwing.uoregon.edu/~noeckel/Illustrator.html
Finally, an answer to Darren's qustion:

I have never been able to get .ps files that will convert to .pdf
using adobe distiller. Always get a font related error and distiller
bails.
But the .eps files work fine for converting to .pdf.
So if I comment out fontenc, will that break .eps but fix .ps?

Getting this result was extremely important to me. I believe that some journals will insist on being able to open the image in, say, adobe illustrator, so they can change the fonts. |

I wanted to test out all the tex related fixes that are in matplotlib
0.87.
Since I couldn't find a binary distribution anywhere I tried building
it from source.
I have python 2.4.2 framework
wxPython 2.6.2.1
I have zlib, freetype, and libpng installed
I downloaded 0.87
ran
python setup.py build
there were no errors but a few warnings about mulitiply defined types

It's an older version that you probably don't want to use, plus it's installed for python 2.3.5 However, when you need to build wx code (which the wxagg back-end does), you can use the wx-config utility to find out what libs to link etc. Apple has installed a wx-config into /usr/bin/wx-config that points to their install of wx.

I found wx-config in
/usr/local/lib/wxPython-ansi-2.6.2.1/bin
./wx-config --version
2.6.2
there is another wx-config in /usr/bin that returns 2.5.3 for the
version
in setupext.py is the following function
def find_wx_config():
"""If the WX_CONFIG environment variable has been set, returns
it value.
Otherwise, search for `wx-config' in the PATH directories and
return the
first match found. Failing that, return None.
"""
wxconfig = os.getenv('WX_CONFIG')
if wxconfig is not None:
return wxconfig
path = os.getenv('PATH') or ''
for dir in path.split(':'):
wxconfig = os.path.join(dir, 'wx-config')
if os.path.exists(wxconfig):
return wxconfig
return None
I checked and I didn't have WX_CONFIG environment variable set to
anything.
so I set the environment variable
export WX_CONFIG="usr/local/lib/wxPython-ansi-2.6.2.1/bin/wx-config"
AlBook:smithsm$ echo $WX_CONFIG
usr/local/lib/wxPython-ansi-2.6.2.1/bin/wx-config
I removed the build directory rm -r build then I
python setup.py clean
python setup.py build
sudo python setup.py clean
but the problem does not go away!
from the debug output below it states that
the WXAgg backend is version 2.6.2.1
So I don't know what to do?

Setting the WX_CONFIG environment variable before the build fixed one
problem. It is now finding my matplotlibrc file.
I thought maybe it was a font corruption problem but it I use TkAgg
everything works fine with my 0.87.1cvs build. So
I think maybe I have uncovered a bug in the WXAgg? I would like to
help fix it but I don't have a clue of where to start.
I also tried WxAgg with the first fonts in the rc file set to the
ones that come installed with matplotlib
font.serif : Bitstream Vera Serif
font.sans-serif : Bitstream Vera Sans
and it still crashes. So something is wrong. Maybe its my
environment. It would be nice if someone could verify
if they get the same problem

This sure looks like your error occurs when MPL is trying to convert
from the wxagg internal image storage to a wxBitmap. As a test, I'd make
sure the pure Agg back-end works fine (have it create a PNG). If so then
font,s etc have nothing to do withyour trouble...it's all about the agg
-> wx conversion. that's why I thought it could be caused by liniking to
the wrong version of wx.
to make sure you have linked to the right version, you can use:
otool -L
on the wxagg libs that MPL builds. That should tell you which wx libs
you've actuallylinked to.
With any luck, I'll have a chance to try to get this working on my
system this week, and then maybe I'll be more help.
-Chris

Onsi Fakhouri had the same problem and found a workaround. But I appreciate your help the WX_AGG environment variable fixed one problem and your information on the linking tool should prove useful to verify that things are getting build correctly. See my post today titled "Workaround for 0.87 WXAgg bug". Apparently according to Onsi there is a bug in the C code, memory is not being allocated correctly.

The following discussion addresses a problem found in the latex code, and has
nothing to do with the dvipng hack. I am working on fixing these problems in
cvs, but I need to do some testing first.

There is some issue related to the dvipng hack that I dont understand. Robert
and Samuel want to apply the hack to dvipng version 1.6. I also have version
1.6, but if I apply the hack, then my output doesnt look right. Whats going
on here? Are there two OS dependent versions of dvipng-1.6?

According to the release notes for 1.6
The 1.6 release adds proper alpha channel support and xcolor
support. It also reestablishes identification of preview-latex'
tightpage mode option.
Not sure why we are seeing differences between 1.6 on different
platforms, unless there is an endian issue in the png files.
