Struct PerspectiveTransform 

pub struct PerspectiveTransform {
    pub homography: HomographyMatrix,
}

Perspective (homography) transform applied to RGBA images.

Fields

homography: HomographyMatrix

The forward homography (src → dst mapping).

Implementations

impl PerspectiveTransform

pub fn new(homography: HomographyMatrix) -> Self

Create a new perspective transform with the given homography.

pub fn warp_rgba( &self, src: &[u8], src_w: u32, src_h: u32, dst: &mut [u8], dst_w: u32, dst_h: u32, ) -> Result<()>

Apply a perspective warp to an RGBA source image.

Uses backward-mapping: for each destination pixel, the inverse homography maps it to a source coordinate, which is sampled bilinearly.

Out-of-bounds source coordinates are filled with black ([0, 0, 0, 0]).

Errors

Returns an error if buffer sizes are inconsistent or if the homography is not invertible.

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

Formats the value using the given formatter.
