Struct kurbo::Ellipse

pub struct Ellipse { /* fields omitted */ }

An ellipse.

Implementations

impl Ellipse

pub fn new(
    center: impl Into<Point>,
    radii: impl Into<Vec2>,
    x_rotation: f64
) -> Ellipse

A new ellipse from center, radii, and x_rotation.

The returned ellipse will be the result of taking a circle, stretching it by the radii along the x and y axes, then rotating it clockwise by x_rotation radians, before finally translating the center to center.

pub fn from_rect(rect: Rect) -> Self

Returns the largest ellipse that can be bounded by this Rect.

This uses the absolute width and height of the rectangle.

This ellipse is always axis-aligned; to apply rotation you can call with_x_rotation with the result.

pub fn from_affine(affine: Affine) -> Self

Create an ellipse from an affine transformation of the unit circle.

pub fn center(&self) -> Point

Returns the center of this ellipse.

pub fn with_center(self, new_center: Point) -> Ellipse

Sets the center of this ellipse.

pub fn radii(&self) -> Vec2

Returns the two radii of this ellipse.

The first number is the horizontal radius and the second is the vertical radius, before rotating by x_rotation.

#[must_use]pub fn with_radii(self, new_radii: Vec2) -> Ellipse

Set the radii of this ellipse.

pub fn x_rotation(&self) -> f64

The amount (in radians) that the ellipse should be rotated by (clockwise).

This allows all possible ellipses to be drawn by always starting with an ellipse with the two radii on the x and y axes.

pub fn with_x_rotation(self, new_x_rotation: f64) -> Ellipse

Set the amount (in radians) that the ellipse should be rotated by (clockwise).
