Trait Implementations

impl Build for Builder

type PathType = Path

The type of object that is created by this builder.

fn build(self) -> Path

Builds a path object and resets the builder so that it can be used again.

fn build_and_reset(&mut self) -> Path

Builds a path object and resets the builder so that it can be used again.

impl FlatPathBuilder for Builder

fn move_to(&mut self, to: Point)

Sets the current position in preparation for the next sub-path. If the current sub-path contains edges, this ends the sub-path without closing it.

fn line_to(&mut self, to: Point)

Adds a line segment to the current sub-path and set the current position.

fn close(&mut self)

Closes the current sub path and sets the current position to the first position of this the current sub-path.

fn current_position(&self) -> Point

fn flattened(self, tolerance: f32) -> FlatteningBuilder<Self> where
    Self: Sized, 

Returns a builder that approximates all curves with sequences of line segments.

impl PathBuilder for Builder

fn quadratic_bezier_to(&mut self, ctrl: Point, to: Point)

fn cubic_bezier_to(&mut self, ctrl1: Point, ctrl2: Point, to: Point)

fn arc(
    &mut self,
    center: Point,
    radii: Vector,
    sweep_angle: Angle,
    x_rotation: Angle
)

fn path_event(&mut self, event: PathEvent)

fn with_svg(self) -> SvgPathBuilder<Self> where
    Self: Sized, 

Returns a builder that support svg commands.

impl PolygonBuilder for Builder

fn polygon(&mut self, points: &[Point])

Add a closed polygon.
