<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>
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 (in my understanding) free for noncommercial use.<br>
For commercial use, please consult the licenses in fonts/ttf and the<br>
author Basil K. Malyshev - see also<br>
<a href="http://www.mozilla.org/projects/mathml/fonts/encoding/license-bakoma.txt">http://www.mozilla.org/projects/mathml/fonts/encoding/license-bakoma.txt</a><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>
<br>
BACKENDS<br>
<br>
mathtext currently works with GTK, Agg, GTKAgg, TkAgg and WxAgg. If<br>
David incorporates ft2font into paint, it will be easy to add to<br>
Paint. WX can follow the lead of GTK and use pixels API calls to<br>
use mathtext.<br>
<br>
PS will require more substantial work, doing the metrics and<br>
layouts with the AFM versions of the computer modern fonts.<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>
- some hackish ways I deal with a strange offset in cmex10<br>
- nested subscripts, eg, x_i_i not working<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>

Create a new FT2Font object<br>
The following global font attributes are defined:<br>
num_faces number of faces in file<br>
face_flags face flags (int type); see the ft2font constants<br>
style_flags style flags (int type); see the ft2font constants<br>
num_glyphs number of glyphs in the face<br>
family_name face family name<br>
style_name face syle name<br>
num_fixed_sizes number of bitmap in the face<br>
scalable face is scalable<br>

The following are available, if scalable is true:<br>
bbox face global bounding box (xmin, ymin, xmax, ymax)<br>
units_per_EM number of font units covered by the EM<br>
ascender ascender in 26.6 units<br>
descender descender in 26.6 units<br>
height height in 26.6 units; used to compute a default<br>
line spacing (baseline-to-baseline distance)<br>
