}

Monospaced bitmap font.

Associated Constants

const FONT_IMAGE: &'static [u8]

Raw image data containing the font.

const FONT_IMAGE_WIDTH: u32

The width of the raw image data.

The width must be divisible by 8 and CHARACTER_SIZE.width.

const CHARACTER_SIZE: Size

Size of a single character in pixel.

const CHARACTER_SPACING: u32

Spacing between characters.

The spacing defines how many empty pixels are added horizontally between adjacent characters on a single line of text.

const VARIABLE_WIDTH: bool

Whether characters have a variable width or not.

Variable width characters have a maximum width of CHARACTER_SIZE.x, but the empty columns at the right of each characters are ignored, allowing some characters to be smaller than others.

Required methods

fn char_offset(_: char) -> u32

Returns the position a character in the font.

Provided methods

fn char_width(c: char) -> u32

Returns the actual width of a character in the font.

fn character_pixel(c: char, x: u32, y: u32) -> bool

Returns the value of a pixel in a character in the font.
