Uses 25 bytes of storage.

Implementations

source

impl GreyscaleImage

source

pub const fn new(data: &[[u8 ; 5]; 5]) -> GreyscaleImage

Constructs a GreyscaleImage from an array of brightnesses.

The data should be an array of 5 rows (top first), each of which is an array of 5 brightness values (left first).

Example

const GREY_HEART: GreyscaleImage = GreyscaleImage::new(&[
    [0, 9, 0, 9, 0],
    [9, 5, 9, 5, 9],
    [9, 5, 5, 5, 9],
    [0, 9, 5, 9, 0],
    [0, 0, 9, 0, 0],
]);

source

pub const fn blank() -> GreyscaleImage

Construct a GreyscaleImage with all LEDs turned off.
