Struct Canvas 

pub struct Canvas { /* private fields */ }

Pixels being drawn, premultiplied, in floats.

Implementations

impl Canvas

pub fn draw( &mut self, ops: &[Op], to_px: impl Fn(Vec2) -> Vec2, scale: f32, current: Color, )

ops painted: each point through to_px (the drawing’s units to the canvas’s pixels, scale pixels a unit), parts without a color in current.

impl Canvas

pub fn new(w: u32, h: u32) -> Canvas

A transparent w × h canvas.

pub fn width(&self) -> u32

pub fn height(&self) -> u32

pub fn fill(&mut self, contours: &[Vec<Vec2>], color: Color)

The inside of contours (closed polylines; an open one is closed) painted color.

pub fn stroke(&mut self, polylines: &[Vec<Vec2>], width: f32, color: Color)

polylines drawn width wide in color, round-joined and capped.

pub fn image(&mut self, image: &Image, dst: Rect, tint: Option<Color>)

image sampled (nearest) into dst, its colors multiplied by tint if given.

pub fn mask(&mut self, mask: &Mask, dst: Rect, color: Color)

mask in box dst (pixels), its set pixels color.

pub fn into_image(self) -> Image

The drawing, straight alpha.
