For a tutorial of its usage, see :ref:`mathtext`. This document is primarily concerned with implementation details. The module uses pyparsing_ to parse the TeX expression. .. _pyparsing: https://pypi.org/project/pyparsing/ 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 *prop* is provided, it is a `.FontProperties` object specifying the "default" font to use in the math expression, used for all non-math text. The results are cached, so multiple calls to `parse` with the same expression should be fast. Depending on the *output* type, this returns either a `VectorParse` or a `RasterParse`.
