There are various display emulators available for running code against, for debugging and screen capture functionality:

• The :py:class:`luma.emulator.device.capture` device will persist a numbered PNG file to disk every time its display method is called.
• The :py:class:`luma.emulator.device.gifanim` device will record every image when its display method is called, and on program exit (or Ctrl-C), will assemble the images into an animated GIF.
• The :py:class:`luma.emulator.device.pygame` device uses the pygame library to render the displayed image to a pygame display surface.

Check out the examples on how to use the luma.emulator devices.
