Struct math2d::RoundedRect

#[repr(C)]
pub struct RoundedRect {
    pub rect: Rectf,
    pub radius_x: f32,
    pub radius_y: f32,
}

Represents a rectangle with rounded corners described by ellipses that touch the internal edges of the rectangle at the tangent points.

Fields

rect: Rectf

The overall rectangle containing this rounded rectangle

radius_x: f32

The x-radius of the ellipse nested in each corner.

radius_y: f32

The y-radius of the ellipse nested in each corner.

Methods

impl RoundedRect

pub fn new(
    rect: impl Into<Rectf>,
    rx: f32,
    ry: f32
) -> RoundedRect

Constructs the rounded rectangle from its components

pub fn corner_ellipse(&self, corner: RectCorner) -> Ellipse

Gets the ellipse that resides in the given corner of the rectangle

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

Checks if the given point resides within the rounded rectangle, taking care to exclude the parts of the corners that are excluded from the ellipses.

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

Checks if the point resides within the rectangle without checking the corner cases of being inside the square rectangle but not inside the rounded corners. This function may be decently faster than contains_point.
