Struct rpi_memory_display::MemoryDisplayBuffer

pub struct MemoryDisplayBuffer { /* fields omitted */ }

A display buffer suitable for use with MemoryDisplay::update().

Implementations

impl MemoryDisplayBuffer

pub fn new(width: usize, height: u8) -> Self

Creates a new buffer.

pub fn fill(&mut self, value: Pixel)

Set all pixels in buffer to value.

pub fn set_pixel(&mut self, x: usize, y: u8, value: Pixel)

Sets the pixel at the given co-ordinates. Set value true for white, false for black.

Panics

Panics if (x, y) is out of the bounds (width, height).

pub fn get_pixel(&self, x: usize, y: u8) -> Pixel

Returns value of pixel at given co-ordinates. Returns true for white, false for black.

Panics

Panics if (x, y) is out of the bounds (width, height).
