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) i����( t print_functionN( t Popent PIPEt STDOUT( t md5( t rcParams( t read_png( t mkdirst wint &t ;c C s� t d d t d t d t d t d t j d k �} | j | j } } x{ | D]s } | j d � rM | j � d } t j j d | d � | j d � } t j j | � } | t j j d � k SqM Wt j j d d � t S( Ns dvipng -versiont shellt stdint stdoutt stderrt close_fdst win32s dvipng i����s Found dvipng version %st helpfult asciis 1.6s No dvipng was found( R t TrueR R t syst platformR R t startswitht splitt mplt verboset reportt decodet distutilst versiont LooseVersiont False( t pR R t lineR ( ( s; /usr/lib64/python2.7/site-packages/matplotlib/texmanager.pyt dvipng_hack_alpha< s t TexManagerc B sT e Z d Z e j � Z e d@ k r3 e j � Z n e j j e d � Z e j � Z e j j e d � Z e j j e � r� e d e e f d e j �e j e e � n e e � d@ Z i Z i Z i Z d Z dA Z dB Z dC Z dD Z d Z dE Z i dF d 6dG d 6dH d 6dI d 6dJ d 6dK d 6dL d 6dM d 6dN d 6dO d" 6dP d% 6dQ d( 6dR d 6dS d) 6dT d* 6dU d+ 6Z! d@ Z" dV e# g dW e D] Z$ d. e$ ^ q�� Z% d/ � Z& d@ d0 � Z' d1 � Z( d2 � Z) d3 � Z* d4 � Z+ d5 � Z, e- j. d6 � Z/ d7 � Z0 d8 � Z1 d9 � Z2 d: � Z3 d; � Z4 d< � Z5 d@ d@ d= � Z6 d@ d@ dX d> � Z7 d@ d? � Z8 RS(Y sZ Convert strings to dvi files using TeX, caching the results to a working dir s .tex.caches tex.cachesm WARNING: found a TeX cache dir in the deprecated location "%s".
