qu2cu: Convert quadratic curves to cubic
########################################
.. rubric:: Overview
:heading-level: 2
Routines for converting quadratic curves to cubic splines, suitable for use
in TrueType to CFF-flavored OpenType outline conversion.
The basic curve conversion routines are implemented in the
:mod:`fontTools.qu2cu.qu2cu` module.
.. note:: The redundancy in the module name is a workaround made
made necessary by :mod:`fontTools.qu2cu`'s usage of
`Cython <https://cython.org/>`_. Providing Cython support
for the module enables faster execution on systems where
Cython is available. However, the module remains fully
available on systems without Cython, too.

qu2cu also includes a submodule that implements the
``fonttools qu2cu`` command for converting a UFO format font with
quadratic curves into one with cubic curves:
