This module supports embedded TeX expressions in matplotlib via dvipng and dvips for the raster and postscript backends. The tex and dvipng/dvips information is cached in ~/.matplotlib/tex.cache for reuse between sessions Requirements: * latex * \*Agg backends: dvipng * PS backend: latex w/ psfrag, dvips, and Ghostscript 8.51 (older versions do not work properly) Backends: * \*Agg * PS * PDF For raster output, you can get RGBA numpy arrays from TeX expressions as follows:: texmanager = TexManager() s = '\TeX\ is Number $\displaystyle\sum_{n=1}^\infty\frac{-e^{i\pi}}{2^n}$!' Z = self.texmanager.get_rgba(s, size=12, dpi=80, rgb=(1,0,0)) To enable tex rendering of all text in your matplotlib figure, set text.usetex in your matplotlibrc file (http://matplotlib.sf.net/matplotlibrc) or include these two lines in your script:: from matplotlib import rc rc('text', usetex=True)

Classes

TexManager

class TexManager

Convert strings to dvi files using TeX, caching the results to a working dir

Methods defined here:

__init__(self)

get_basefile(self, tex, fontsize, dpi=None)
returns a filename based on a hash of the string, fontsize, and dpi

get_custom_preamble(self)
returns a string containing user additions to the tex preamble

get_font_config(self)
Reinitializes self if relevant rcParams on have changed.

get_font_preamble(self)
returns a string containing font configuration for the tex preamble

get_grey(self, tex, fontsize=None, dpi=None)
returns the alpha channel

get_ps_bbox(self, tex, fontsize)
returns a list containing the postscript bounding box for latex's rendering of the tex string

get_rgba(self, tex, fontsize=None, dpi=None, rgb=(0, 0, 0))
Returns latex's rendering of the tex string as an rgba array

make_dvi(self, tex, fontsize)
generates a dvi file containing latex's layout of tex string returns the file name

make_png(self, tex, fontsize, dpi)
generates a png file containing latex's rendering of tex string returns the filename

make_ps(self, tex, fontsize)
generates a postscript file containing latex's rendering of tex string returns the file name

make_tex(self, tex, fontsize)
Generate a tex file to render the tex string at a specific font size returns the file name
