Struct Rasterizer 

pub struct Rasterizer { /* private fields */ }

Accumulation-buffer scanline rasterizer producing an A8 coverage bitmap of a fixed width × height.

Implementations

impl Rasterizer

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

Create a rasterizer for a width × height coverage bitmap.

pub fn line(&mut self, x0: f32, y0: f32, x1: f32, y1: f32)

Add a straight edge between two points in pixel coordinates.

Edges may be supplied in any order; their signed contributions combine so that a closed contour yields correct non-zero-winding coverage.

pub fn quad(&mut self, x0: f32, y0: f32, cx: f32, cy: f32, x1: f32, y1: f32)

Add a quadratic Bézier, flattened to line segments.

pub fn cubic( &mut self, x0: f32, y0: f32, c1x: f32, c1y: f32, c2x: f32, c2y: f32, x1: f32, y1: f32, )

Add a cubic Bézier, flattened to line segments.

pub fn finish(&self) -> Vec<u8>

Resolve the accumulation buffer into an A8 coverage bitmap (width * height bytes, row-major).
