<p><tt>OVERVIEW <br>
<br>
mathtext is a module for parsing TeX expressions and drawing them<br>
into a matplotlib.ft2font image buffer. You can draw from this<br>
buffer into your backend.<br>
<br>
A large set of the TeX symbols are provided (see below).<br>
Subscripting and superscripting are supported, as well as the<br>
over/under style of subscripting with \sum, \int, etc.<br>
<br>
The module uses pyparsing to parse the TeX expression, an so can<br>
handle fairly complex TeX expressions Eg, the following renders<br>
correctly<br>
<br>
s = r'$\cal{R}\prod_{i=\alpha\cal{B}}^\infty a_i\rm{sin}(2 \pi f x_i)$'<br>
<br>
The fonts \cal, \rm, \it, and \tt are allowed.<br>
<br>
The following accents are provided: \hat, \breve, \grave, \bar,<br>
\acute, \tilde, \vec, \dot, \ddot. All of them have the same<br>
syntax, eg to make an overbar you do \bar{o} or to make an o umlaut<br>
you do \ddot{o}. The shortcuts are also provided, eg: \"o \'e \`e<br>
\~n \.x \^y<br>
<br>
The spacing elements \ , \/ and \hspace{num} are provided. \/<br>
inserts a small space, and \hspace{num} inserts a fraction of the<br>
current fontsize. Eg, if num=0.5 and the fontsize is 12.0,<br>
hspace{0.5} inserts 6 points of space<br>
<br>
<br>
<br>
If you find TeX expressions that don't parse or render properly,<br>
please email me, but please check KNOWN ISSUES below first.<br>
<br>
REQUIREMENTS<br>
<br>
mathtext requires matplotlib.ft2font. Set BUILD_FT2FONT=True in<br>
setup.py. See BACKENDS below for a summary of availability by<br>
backend.<br>
<br>
LICENSING:<br>
<br>
The computer modern fonts this package uses are part of the BaKoMa<br>
fonts, which are (now) free for commercial and noncommercial use and<br>
redistribution; see license/LICENSE_BAKOMA in the matplotlib src<br>
distribution for redistribution requirements.<br>
<br>
USAGE:<br>
<br>
See <a href="http://matplotlib.sourceforge.net/tutorial.html#mathtext">http://matplotlib.sourceforge.net/tutorial.html#mathtext</a> for a<br>
tutorial introduction.<br>
<br>
Any text element (xlabel, ylabel, title, text, etc) can use TeX<br>
markup, as in<br>
<br>
xlabel(r'$\Delta_i$')<br>
^<br>
use raw strings<br>
<br>
The $ symbols must be the first and last symbols in the string. Eg,<br>
you cannot do <br>
<br>
r'My label $x_i$'. <br>
<br>
but you can change fonts, as in <br>
<br>
r'$\rm{My label} x_i$' <br>
<br>
to achieve the same effect.<br>
<br>
A large set of the TeX symbols are provided. Subscripting and<br>
superscripting are supported, as well as the over/under style of<br>
subscripting with \sum, \int, etc.<br>
<br>
<br>

<br>
BACKENDS<br>
<br>
mathtext currently works with GTK, Agg, GTKAgg, TkAgg and WxAgg and<br>
PS, though only horizontal and vertical rotations are supported in<br>
*Agg<br>
<br>
mathtext now embeds the TrueType computer modern fonts into the PS<br>
file, so what you see on the screen should be what you get on paper.<br>
<br>
Backends which don't support mathtext will just render the TeX<br>
string as a literal. Stay tuned.<br>
<br>
<br>
KNOWN ISSUES:<br>
<br>
- nested subscripts, eg, x_i_j not working; but you can do x_{i_j}<br>
- nesting fonts changes in sub/superscript groups not parsing<br>
- I would also like to add a few more layout commands, like \frac.<br>
