[−]Struct druid::piet::kurbo::Arc
A single arc segment.
Fields
center: Point
The arc's centre point.
radii: Vec2
The arc's radii, where the vector's x-component is the radius in the
positive x direction after applying x_rotation
.
start_angle: f64
The start angle in radians.
sweep_angle: f64
The angle between the start and end of the arc, in radians.
x_rotation: f64
How much the arc is rotated, in radians.
Implementations
impl Arc
pub fn append_iter(&self, tolerance: f64) -> ArcAppendIter
Create an iterator generating Bezier path elements.
The generated elemets can be append to an existing bezier path.
pub fn to_cubic_beziers<P>(self, tolerance: f64, p: P) where
P: FnMut(Point, Point, Point),
P: FnMut(Point, Point, Point),
Converts an Arc into a series of cubic bezier segments.
Closure will be invoked for each segment.
impl Arc
pub fn from_svg_arc(arc: &SvgArc) -> Option<Arc>
Creates an Arc
from a SvgArc
.
Returns None
if arc
is actually a straight line.

type PathElementsIter = Chain<Once<PathEl>, ArcAppendIter>
The iterator returned by the path_elements
method. Read more
pub fn path_elements(&self, tolerance: f64) -> <Arc as Shape>::PathElementsIter
pub fn area(&self) -> f64
Note: shape isn't closed so area is not well defined.
pub fn perimeter(&self, accuracy: f64) -> f64
Note: Finding the perimiter of an ellipse is fairly involved, so for now just approximate by using the bezier curve representation. (See https://en.wikipedia.org/wiki/Ellipse#Circumference)
pub fn winding(&self, pt: Point) -> i32
Note: shape isn't closed so a point's winding number is not well defined.
