Implementations§

source§

impl Ellipse

source

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

Create A new ellipse with a given center, radii, and 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 from the x axis by rotation radians, before finally translating the center to center.

Rotation is clockwise in a y-down coordinate system. For more on rotation, see Affine::rotate.

source

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_rotation with the result.

source

pub fn from_affine(affine: Affine) -> Self

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

source

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

Create a new Ellipse centered on the provided point.

source

pub fn with_radii(self, new_radii: Vec2) -> Ellipse

Create a new Ellipse with the provided radii.

source

pub fn with_rotation(self, rotation: f64) -> Ellipse

Create a new Ellipse, with the rotation replaced by rotation radians.

The rotation is clockwise, for a y-down coordinate system. For more on rotation, See Affine::rotate.

source

pub fn center(&self) -> Point

Returns the center of this ellipse.

source

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 rotation.

source

pub fn rotation(&self) -> f64

The ellipse’s rotation, in radians.

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

source

pub fn radii_and_rotation(&self) -> (Vec2, f64)

Returns the radii and the rotation of this ellipse.

Equivalent to (self.radii(), self.rotation()) but more efficient.

source

pub fn is_finite(&self) -> bool

Is this ellipse finite?

source

pub fn is_nan(&self) -> bool

Is this ellipse NaN?
