Methods

impl BezierCurveItem

pub fn get_first_point(&self) -> Point

Returns the start point of the curve

pub fn get_last_point(&self) -> Point

Returns the end point of the curve

pub fn from_str(s: &str) -> Result<Self, ParseError>

Parses the BezierCurveItem from a string

let parsed1 = BezierCurveItem::from_str("(0.0 1.0, 2.0 1.0)").unwrap();
assert_eq!(parsed1, Line((Point { x: 0.0, y: 1.0 }, Point { x: 2.0, y: 1.0 })));

let parsed2 = BezierCurveItem::from_str("(0.0 1.0, 2.0 1.0, 3.0 4.0)").unwrap();
assert_eq!(parsed2, QuadraticCurve((Point { x: 0.0, y: 1.0 }, Point { x: 2.0, y: 1.0 }, Point { x: 3.0, y: 4.0 })));

pub fn get_max_x(&self) -> f64

Returns the x

max value of the BezierCurveItem - useful for calculating bounding boxes

pub fn get_min_x(&self) -> f64

Returns the x

min value of the BezierCurveItem - useful for calculating bounding boxes

pub fn get_max_y(&self) -> f64

Returns the y

max value of the BezierCurveItem - useful for calculating bounding boxes

pub fn get_min_y(&self) -> f64

Returns the y

min value of the BezierCurveItem - useful for calculating bounding boxes

pub fn get_bbox(&self) -> Bbox

Returns the bounding box of this item

pub fn intersect(&self, curve: &Self) -> IntersectionResult

Returns the intersection of two items (line-curve, curve-curve or line-line intersection).

Warning: calling this function is expensive, it's recommended to cull items that don't intersect first by intersecting their bounding boxes.

pub fn normal(&self, t: f64) -> BezierNormalVector

Returns the normal of the curve / line at t

pub fn split_at(&self, t: f64) -> (Self, Self)

Splits the curve / line into two curves / lines
