Struct microbit::display::image::BitImage[][src]

pub struct BitImage(_);
Expand description

A 5×5 image supporting only two levels of brightness (on and off).

Uses 5 bytes of storage.

For display, each pixel is treated as having brightness either 0 or MAX_BRIGHTNESS.

Implementations

impl BitImage[src]

pub const fn new(im: &[[u8; 5]; 5]) -> BitImage[src]

Constructs a BitImage from an array of brightnesses.

The data should be an array of 5 rows (top first), each of which is an array of 5 values (left first). Each value should be either 0 or 1.

Example

const HEART: BitImage = BitImage::new(&[
    [0, 1, 0, 1, 0],
    [1, 0, 1, 0, 1],
    [1, 0, 0, 0, 1],
    [0, 1, 0, 1, 0],
    [0, 0, 1, 0, 0],
]);

pub const fn blank() -> BitImage[src]

Returns a new blank BitImage.

All pixel values are 0.
