Detailed description

The font component provides a series of bitmap glyphs to the graphical display components and is built into these components.

Each font can be capable of providing a full character set or just a set of numeric characters, these latter being marked with the word Number.

Custom fonts can be created using the Custom option and providing a link to a file generated by a tool called The Dot Factory.

To do this you must first download and install the dot factory on your computer.
