//| ==========================================================================
//|
//| Loads values straight from disk. This minimizes memory use but can lead to
//| much slower pixel load times. These load times may result in frame tearing where only part of
//| the image is visible.
//|
//| It's easiest to use on a board with a built in display such as the `Hallowing M0 Express
//| <https://www.adafruit.com/product/3900>`_.
