Struct PerspectiveTransform 

pub struct PerspectiveTransform {
    pub matrix: [[f64; 3]; 3],
}

A source-to-destination projective 2D transform.

Fields

matrix: [[f64; 3]; 3]

Homogeneous 3x3 transform matrix.

Implementations

impl PerspectiveTransform

pub const fn identity() -> PerspectiveTransform

Identity projective transform.

pub fn map_point(self, x: f64, y: f64) -> Option<(f64, f64)>

Applies the source-to-destination homogeneous transform.

pub fn inverse(self) -> Result<PerspectiveTransform, VisionError>

Computes the inverse projective transform.

Trait Implementations

impl Clone for PerspectiveTransform

fn clone(&self) -> PerspectiveTransform

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PerspectiveTransform

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

Formats the value using the given formatter.

impl PartialEq for PerspectiveTransform

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