Struct ControlPoint 

pub struct ControlPoint {
    pub source: Point2D,
    pub target: Point2D,
    pub weight: f64,
}

A control point pair used as a landmark for elastic alignment.

Fields

source: Point2D

Source position.

target: Point2D

Target position (where the source should map to).

weight: f64

Weight for this control point (higher means stronger influence).

Implementations

impl ControlPoint

pub fn new(source: Point2D, target: Point2D, weight: f64) -> Self

Create a new control point pair.

pub fn with_unit_weight(source: Point2D, target: Point2D) -> Self

Create with default weight 1.0.

pub fn displacement(&self) -> (f64, f64)

Compute the displacement vector (target - source).

pub fn displacement_magnitude(&self) -> f64

Compute the displacement magnitude.

Trait Implementations

impl Clone for ControlPoint

fn clone(&self) -> ControlPoint

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ControlPoint

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

Formats the value using the given formatter.

impl PartialEq for ControlPoint

fn eq(&self, other: &ControlPoint) -> 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.
