Expand description

“a” command for paths; describes an elliptical arc in terms of its endpoints.

Fields§

§r: (f64, f64)

The (x-axis, y-axis) radii for the ellipse.

§x_axis_rotation: f64

The rotation angle in degrees for the ellipse’s x-axis relative to the x-axis of the user coordinate system.

§large_arc: LargeArc

Flag indicating whether the arc sweep should be greater than or equal to 180 degrees, or smaller than 180 degrees.

§sweep: Sweep

Flag indicating the angular direction in which the arc is drawn.

§from: (f64, f64)

The (x, y) coordinates for the start point of this path segment.

§to: (f64, f64)

The (x, y) coordinates for the end point of this path segment.

Implementations§

source§

impl EllipticalArc

source

fn to_cairo(&self, cr: &Context)

source§

impl EllipticalArc

source

pub(crate) fn center_parameterization(&self) -> ArcParameterization

Calculates a center parameterization from the endpoint parameterization.

Radii may be adjusted if there is no solution.

See section B.2.4. Conversion from endpoint to center parameterization

source

fn from_coords( large_arc: LargeArc, sweep: Sweep, coords: &mut Iter<'_, f64> ) -> EllipticalArc

Consumes 7 coordinates and creates an arc segment.

source

fn to_packed_and_coords(&self, coords: &mut Vec<f64>) -> PackedCommand

Pushes 7 coordinates to coords and returns one of PackedCommand::Arc*.
