Pycairo is a Python module providing bindings for the `cairo graphics library
|
||
<https://cairographics.org/>`__. It depends on **cairo >= 1.13.1** and
|
||
works with **Python 2.7+** as well as **Python 3.4+**. Pycairo, including this
|
||
documentation, is licensed under the **LGPLv2.1** as well as the **MPLv1.1**.
|
||
|
||
The Pycairo bindings are designed to match the cairo C API as closely as
|
||
possible, and to deviate only in cases which are clearly better implemented in
|
||
a more ‘Pythonic’ way.
|
||
|
||
.. code:: shell
|
||
|
||
pip install pycairo
|
||
|
||
Installing Pycairo requires cairo including its headers. For more info see
|
||
"`Getting Started
|
||
<https://pycairo.readthedocs.io/en/latest/getting_started.html>`__".

Features of the Pycairo bindings:
|
||
|
||
* Provides an object oriented interface to cairo.
|
||
* Queries the error status of objects and translates them to exceptions.
|
||
* Provides a C API that can be used by other Python extensions.
|
||
|
||
If Pycairo is not what you need, have a look at `cairocffi
|
||
<https://cairocffi.readthedocs.io>`__, which is an API compatible package
|
||
using `cffi <https://cffi.readthedocs.io/>`__ or `Qahirah
|
||
<https://github.com/ldo/qahirah>`__, which is using `ctypes
|
||
<https://docs.python.org/3/library/ctypes.html>`__ and provides a more
|
||
"pythonic" API with less focus on matching the cairo C API.
