Struct lyon_algorithms::walk::PathWalker

pub struct PathWalker<'l> { /* fields omitted */ }

A helper struct to walk along a flattened path using a builder API.

Implementations

impl<'l> PathWalker<'l>

pub fn new(start: f32, pattern: &'l mut dyn Pattern) -> PathWalker<'l>

Trait Implementations

impl<'l> FlatPathBuilder for PathWalker<'l>

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>

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

impl<'l> PathBuilder for PathWalker<'l>

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: Event<Point2D<f32, UnknownUnit>, Point2D<f32, UnknownUnit>>
)

fn with_svg(self) -> SvgPathBuilder<Self>

Returns a builder that support svg commands.

impl<'l> PolygonBuilder for PathWalker<'l>

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

Add a closed polygon.
