Draw a rotating face
=====================================

This demo shows a couple of uses of bitmap images. You can use them either as textures for images or as the mask for another texture (the face on the left is used as a mask for a blue and yellow grating).

To work the demo needs a square image called face.jpg (e.g. :download:`/images/face.jpg`)

.. image:: /images/demo_face.jpg
   :target: documentation.html
   :alt: draw a drifting plaid

.. literalinclude:: face.py
