Struct Homography 

pub struct Homography {
    pub h: Matrix3<f64>,
}

A 3×3 projective homography matrix.

Maps 2D points between two projective planes: p_dst ~ H * p_src.

Fields

h: Matrix3<f64>

Implementations

impl Homography

pub fn new(h: Matrix3<f64>) -> Self

pub fn from_array(rows: [[f64; 3]; 3]) -> Self

pub fn to_array(&self) -> [[f64; 3]; 3]

pub fn zero() -> Self

pub fn apply(&self, p: Point2<f32>) -> Point2<f32>

Apply the homography to a 2D point.

pub fn inverse(&self) -> Option<Self>

Compute the inverse homography, if the matrix is invertible.

Trait Implementations

impl Clone for Homography

fn clone(&self) -> Homography

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Homography

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

Formats the value using the given formatter.

impl PartialEq for Homography

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