Detailed Description

a font stored as inline constant data (in ROM)

An inline_font is a photo of a line of characters, stored in in-line data (in ROM). As it is a photo, you can draw it in a frame to see how the characters look.

The common way to use a font is to use it to construct a text object, which can subsequently be drawn.

The inline.py tool can be used to convert a .jpg or .bmp file into the .h and .cpp file for an inline_font. This is likely to be the only way you will instantiate this class.
