Struct math2d::Ellipse

#[repr(C)]
pub struct Ellipse {
    pub center: Point2f,
    pub radius_x: f32,
    pub radius_y: f32,
}

Contains the center point, x-radius, and y-radius of an ellipse.

Fields

center: Point2f

The center point of the ellipse.

radius_x: f32

The X-radius of the ellipse.

radius_y: f32

The Y-radius of the ellipse.

Methods

impl Ellipse

pub fn new(center: impl Into<Point2f>, rx: f32, ry: f32) -> Ellipse

Constructs an ellipse from its components

pub fn contains_point(&self, point: impl Into<Point2f>) -> bool

Checks if an ellipse contains a point

pub fn contains_point_transformed(
    &self,
    transform: &Matrix3x2f,
    point: impl Into<Point2f>
) -> bool

Determines if an ellipse which has a transform applied to it contains a specified (non- or pre-transformed) point.

Will always return false if !transform.is_invertible()

Trait Implementations

impl PartialEq<Ellipse> for Ellipse

fn eq(&self, other: &Ellipse) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Ellipse) -> bool

This method tests for !=.

impl Default for Ellipse

fn default() -> Ellipse

Returns the "default value" for a type.

impl Clone for Ellipse

fn clone(&self) -> Ellipse

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<P> From<(P, f32, f32)> for Ellipse where
    P: Into<Point2f>, 

fn from(data: (P, f32, f32)) -> Ellipse

Performs the conversion.

impl From<Ellipse> for D2D1_ELLIPSE

fn from(e: Ellipse) -> D2D1_ELLIPSE

Performs the conversion.
