Struct de_controller::hud::minimap::draw::Drawing

pub(super) struct Drawing<'a> {
    size: UVec2,
    data: &'a mut [u8],
}

This struct holds a mutable reference to RGBA data buffer and implements various drawing methods on it.

Fields

size: UVec2

data: &'a mut [u8]

Implementations

impl<'a> Drawing<'a>

fn new(size: UVec2, data: &'a mut [u8]) -> Self

pub(super) fn fill(&mut self, color: Color)

Fill whole of the image with a color.

pub(super) fn line(&mut self, start: Vec2, end: Vec2, color: Color)

Fill a rectangle with a color.

pub(super) fn rect(&mut self, center: Vec2, size: Vec2, color: Color)

Fill a rectangle with a color.

Panics

• If center is not contained by rectangle (0, 0) -> (1, 1).

• If size has a non-positive coordinate.

fn line_px(&mut self, start: IVec2, end: IVec2, color: Color)

fn rect_px(&mut self, top_left: UVec2, bottom_right: UVec2, color: Color)

fn rel_pos_to_px(&self, point: Vec2) -> IVec2

Converts relative coordinates to pixel coordinates.

fn set_pixel_bytes(&mut self, x: u32, y: u32, bytes: [u8; 4])

fn color_to_bytes(color: Color) -> [u8; 4]
