Python interface for cairo

Project description

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.move_to(x, y)
context.curve_to(x1, y1, x2, y2, x3, y3)
context.set_source_rgba(1, 0.2, 0.2, 0.6)
context.move_to(x, y)
context.line_to(x1, y1)
context.move_to(x2, y2)
context.line_to(x3, y3)

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.
