Implementations

impl Bitmap4<'_>

pub fn draw_point_page(&mut self, x: i32, y: i32, colour: u8, page: Page)

Draws point on specified page at (x, y) coordinates with colour index whose colour is specified in the background palette. Panics if (x, y) is out of the bounds of the screen.

pub fn draw_point(&mut self, x: i32, y: i32, colour: u8)

Draws point on the non-current page at (x, y) coordinates with colour index whose colour is specified in the background palette. Panics if (x, y) is out of the bounds of the screen.

pub fn set_palette_entry(&mut self, entry: u32, colour: u16)

Sets the colour of colour index in the background palette.
