Struct piet_common::kurbo::RoundedRect

pub struct RoundedRect { /* fields omitted */ }

A rectangle with equally rounded corners.

By construction the rounded rectangle will have non-negative dimensions and radius clamped to half size of the rect.

The easiest way to create a RoundedRect is often to create a Rect, and then call to_rounded_rect.

Implementations

impl RoundedRect

pub fn new(x0: f64, y0: f64, x1: f64, y1: f64, radius: f64) -> RoundedRect

A new rectangle from minimum and maximum coordinates.

The result will have non-negative width, height and radius.

pub fn from_rect(rect: Rect, radius: f64) -> RoundedRect

A new rounded rectangle from a rectangle and corner radius.

The result will have non-negative width, height and radius.

See also Rect::to_rounded_rect, which offers the same utility.

pub fn from_points(
    p0: impl Into<Point>,
    p1: impl Into<Point>,
    radius: f64
) -> RoundedRect

A new rectangle from two Points.

The result will have non-negative width, height and radius.

pub fn from_origin_size(
    origin: impl Into<Point>,
    size: impl Into<Size>,
    radius: f64
) -> RoundedRect

A new rectangle from origin and size.

The result will have non-negative width, height and radius.

pub fn width(&self) -> f64

The width of the rectangle.

pub fn height(&self) -> f64

The height of the rectangle.

pub fn radius(&self) -> f64

Radius of the rounded corners.

pub fn rect(&self) -> Rect

The (non-rounded) rectangle.

pub fn origin(&self) -> Point

The origin of the rectangle.

This is the top left corner in a y-down space.

pub fn center(&self) -> Point

The center point of the rectangle.
