API - Fonts
===========
.. module:: gpiozero.fonts
GPIO Zero includes a concept of "fonts" which is somewhat different to that you
may be familiar with. While a typical printing font determines how a particular
character is rendered on a page, a GPIO Zero font determines how a particular
character is rendered by a series of lights, like LED segments (e.g. with
:class:`~gpiozero.LEDCharDisplay` or :class:`~gpiozero.LEDMultiCharDisplay`).
As a result, GPIO Zero's fonts are quite crude affairs, being little more than
mappings of characters to tuples of LED states. Still, it helps to have a
"friendly" format for creating such fonts, and in this module the library
provides several routines for this purpose.
The module itself is typically imported as follows::
from gpiozero import fonts
