Pycairo is a Python module providing bindings for the cairo graphics library. It depends on cairo >= 1.13.1 and works with Python 2.7+ as well as Python 3.3+. 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.

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.

import cairo

surface = cairo.SVGSurface("example.svg", 200, 200)
context = cairo.Context(surface)
x, y, x1, y1 = 0.1, 0.5, 0.4, 0.9
x2, y2, x3, y3 = 0.6, 0.1, 0.9, 0.5
context.scale(200, 200)
context.set_line_width(0.04)
context.move_to(x, y)
context.curve_to(x1, y1, x2, y2, x3, y3)
context.stroke()
context.set_source_rgba(1, 0.2, 0.2, 0.6)
context.set_line_width(0.02)
context.move_to(x, y)
context.line_to(x1, y1)
context.move_to(x2, y2)
context.line_to(x3, y3)
context.stroke()
surface.finish()

If Pycairo is not what you need, have a look at cairocffi, which is an API compatible package using cffi or Qahirah, which is using ctypes and provides a more “pythonic” API with less focus on matching the cairo C API.

To use the pycairo library:

import cairo

To build/install the library:

python2/3 setup.py build
python2/3 setup.py install

To run the tests:

python2/3 setup.py test

The Python 2 version supports xpyb integration which is disabled by default. To enable, build as follows:

python2 setup.py build --enable-xpyb
# and for running tests:
python2 setup.py test --enable-xpyb

For examples of pycairo code see the ‘examples’ directory that comes with the pycairo distribution.
