Struct nannou::draw::primitive::ellipse::Ellipse

pub struct Ellipse { /* private fields */ }

Properties related to drawing an Ellipse.

Implementations

impl Ellipse

pub fn stroke<C>(self, color: C) -> Self

where C: IntoLinSrgba<ColorScalar>,

Stroke the outline with the given color.

pub fn radius(self, radius: f32) -> Self

Specify the width and height of the Ellipse via a given radius.

pub fn resolution(self, resolution: f32) -> Self

By default, ellipse does not use a resolution, but rather uses a stroke tolerance to determine how many vertices to use during tessellation.
