Struct piet_common::kurbo::RoundedRectRadii

pub struct RoundedRectRadii {
    pub top_left: f64,
    pub top_right: f64,
    pub bottom_right: f64,
    pub bottom_left: f64,
}

Radii for each corner of a rounded rectangle.

The use of top as in top_left assumes a y-down coordinate space. Piet (and Druid by extension) uses a y-down coordinate space, but Kurbo also supports a y-up coordinate space, in which case top_left would actually refer to the bottom-left corner, and vice versa. Top may not always actually be the top, but top corners will always have a smaller y-value than bottom corners.

Fields

top_left: f64

The radius of the top-left corner.

top_right: f64

The radius of the top-right corner.

bottom_right: f64

The radius of the bottom-right corner.

bottom_left: f64

The radius of the bottom-left corner.

Implementations

impl RoundedRectRadii

pub const fn new(
    top_left: f64,
    top_right: f64,
    bottom_right: f64,
    bottom_left: f64
) -> RoundedRectRadii

Create a new RoundedRectRadii. This function takes radius values for the four corners. The argument order is “top_left, top_right, bottom_right, bottom_left”, or clockwise starting from top_left.

pub const fn from_single_radius(radius: f64) -> RoundedRectRadii

Create a new RoundedRectRadii from a single radius. The radius argument will be set as the radius for all four corners.

pub fn abs(&self) -> RoundedRectRadii

Takes the absolute value of all corner radii.

pub fn clamp(&self, max: f64) -> RoundedRectRadii

For each corner, takes the min of that corner’s radius and max.

pub fn is_finite(&self) -> bool

Returns true if all radius values are finite.

pub fn is_nan(&self) -> bool

Returns true if any corner radius value is NaN.

pub fn as_single_radius(&self) -> Option<f64>

If all radii are equal, returns the value of the radii. Otherwise, returns None.
