Internal structure used for creating strokes.

Fields

output: BezPath

forward_path: BezPath

backward_path: BezPath

start_pt: Point

start_norm: Vec2

start_tan: Vec2

last_pt: Point

last_tan: Vec2

join_thresh: f64

Implementations

impl StrokeCtx

fn finish(&mut self, style: &Stroke)

Append forward and backward paths to output.

fn finish_closed(&mut self, style: &Stroke)

Finish a closed path

fn do_join(&mut self, style: &Stroke, tan0: Vec2)

fn do_line(&mut self, style: &Stroke, tangent: Vec2, p1: Point)

fn do_cubic( &mut self, style: &Stroke, c: CubicBez, tolerance: f64, opts: StrokeOpts, )

fn do_linear( &mut self, style: &Stroke, c: CubicBez, p: [f64; 4], ref_pt: Point, ref_vec: Vec2, )

Do a cubic which is actually linear.

The p argument is the control points projected to the reference chord. The ref arguments are the inverse map of a projection back to the client coordinate space.

Trait Implementations

impl Default for StrokeCtx

fn default() -> StrokeCtx

Returns the “default value” for a type.
