Introduction

This wiki covers the creation and use of fonts.

Defining a Font

There are two kinds of fonts; fixed width and variable width.

• Fixed width fonts: The first 3 bytes must contain the width, height, and first defined character followed by the font definitions. For example the following is the header and first 2 characters from the 4x6 font definition.

  4,6,32,
  //space
  0b00000000,
  0b00000000,
  0b00000000,
  0b00000000,
  0b00000000,
  0b00000000,
  //!
  0b01000000,
  0b01000000,
  0b01000000,
  0b00000000,
  0b01000000,
  0b00000000,

There must be a full definition for each character; in this case the width of 4 fits into a single byte and the height of 6 means there needs to 6 bytes per character. Since 32 is the first printing character for this font set anything before character 32 will be ignored.

• Variable width fonts: These fonts are defined by having a width of 0, height, and first defined character. An example of a variable width font with a height of 6 and the first printing character being a space.

  0,6,32,
  //space
