For a tutorial of its usage see :ref:`mathtext-tutorial`. This document is primarily concerned with implementation details. The module uses pyparsing_ to parse the TeX expression. .. _pyparsing: http://pyparsing.wikispaces.com/ The Bakoma distribution of the TeX Computer Modern fonts, and STIX fonts are supported. There is experimental support for using arbitrary fonts, but results may vary without proper tweaking and metrics for those fonts. If you find TeX expressions that don't parse or render properly, please email mdroe@stsci.edu, but please check KNOWN ISSUES below first. i(tdivisionN(tStringIO(tceil(tSet(twarn(tinftisinf(tCombinetGrouptOptionaltForwardtLiteralt OneOrMoret ZeroOrMoretParseExceptiontEmptyt ParseResultstSuppresstoneOft StringEndtParseFatalExceptiont FollowedBytRegext ParserElement(tAFM(tBunchtget_realpath_and_stattis_string_liketmaxdict(tFT2FonttFT2ImagetKERNING_DEFAULTtLOAD_FORCE_AUTOHINTtLOAD_NO_HINTING(tfindfonttFontProperties(tlatex_to_bakomatlatex_to_standardttex2unit latex_to_cmextstix_virtual_fonts(t get_data_pathtrcParamsc C s{|djodSyt|SWntj onXyt|idSWn)tj odt}t|nXdS(sget_unicode_index(symbol) -> integer Return the integer index (from the Unicode table) of symbol. *symbol* can be a single unicode character, a TeX command (i.e. r'\pi'), or a Type1 symbol name (i.e. 'phi'). t-i"s\sA'%(symbol)s' is not a valid Unicode character or TeX/Type1 symbolN(tordt TypeErrorR&tstriptKeyErrortlocalst ValueError(tsymboltmessage((s9/usr/lib64/python2.6/site-packages/matplotlib/mathtext.pytget_unicode_index<s  tMathtextBackendcB sDeZdZdZdZdZdZdZdZRS(s The base class for the mathtext backend-specific code.
