a
|

|
|
A module for parsing a subset of the TeX math syntax and rendering it to a
|
|||
|
|
Matplotlib backend.
|
|||
|
|
|
|||
|
|
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.

|||
|
|
|
|||

|
|||
|
|
|
|||
|
|
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.

Create a MathTextParser for the given backend *output*.

Parameters
|
|||
|
|
----------
|
|||
|
|
output : {"path", "agg"}
|
|||
|
|
Whether to return a `VectorParse` ("path") or a
|
|||
|
|
`RasterParse` ("agg", or its synonym "macosx").

|
|||
|
|
Parse the given math expression *s* at the given *dpi*. 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`.
