ctrl_2: SvgPoint

end: SvgPoint

Implementations

impl SvgCubicCurve

pub const fn new( start: SvgPoint, ctrl_1: SvgPoint, ctrl_2: SvgPoint, end: SvgPoint, ) -> Self

Creates a new SvgCubicCurve from start, two control points, and end point

pub fn reverse(&mut self)

Reverses the curve direction in place, swapping start/end and ctrl_1/ctrl_2.

pub fn get_start(&self) -> SvgPoint

Returns the start point of the curve.

pub fn get_end(&self) -> SvgPoint

Returns the end point of the curve.

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

Evaluates the x coordinate of the curve at parameter t in [0, 1].

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

Evaluates the y coordinate of the curve at parameter t in [0, 1].

pub fn get_length(&self) -> f64

Returns the approximate arc length of the curve using linear sampling.

pub fn get_t_at_offset(&self, offset: f64) -> f64

Returns the parameter t corresponding to a given arc-length offset.

pub fn get_tangent_vector_at_t(&self, t: f64) -> SvgVector

Returns the normalized tangent vector at parameter t.

pub fn get_bounds(&self) -> SvgRect

Returns the axis-aligned bounding box of the curve’s control points.

Trait Implementations

impl Clone for SvgCubicCurve

fn clone(&self) -> SvgCubicCurve

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SvgCubicCurve

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for SvgCubicCurve

fn eq(&self, other: &SvgCubicCurve) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for SvgCubicCurve

fn partial_cmp(&self, other: &SvgCubicCurve) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
