Struct PlanarImageView 

pub struct PlanarImageView<'a, T, const CHANNELS: usize> { /* private fields */ }

A read-only, zero-copy planar image view with explicit strides.

Implementations

impl<'a, T, const CHANNELS: usize> PlanarImageView<'a, T, CHANNELS>

pub fn new( width: usize, height: usize, row_stride: usize, plane_stride: usize, data: &'a [T], ) -> Result<Self, ImageError>

Creates a planar view. Strides are measured in scalar elements.

pub fn new_with_metadata( width: usize, height: usize, row_stride: usize, plane_stride: usize, data: &'a [T], metadata: ImageMetadata, ) -> Result<Self, ImageError>

Creates a planar view with validated semantic metadata.

pub const fn width(self) -> usize

Returns image width in pixels.

pub const fn height(self) -> usize

Returns image height in pixels.

pub const fn row_stride(self) -> usize

Returns row stride within a plane.

pub const fn plane_stride(self) -> usize

Returns scalar distance between channel-plane origins.

pub const fn layout(self) -> ImageLayout

Returns physical channel layout.

pub const fn metadata(self) -> ImageMetadata

Returns semantic image metadata.

pub fn get(self, channel: usize, x: usize, y: usize) -> Option<&'a T>

Returns one channel value, or None outside image bounds.

pub fn pixel(self, x: usize, y: usize) -> Option<[T; CHANNELS]>

where T: Copy,

Copies one pixel from its channel planes.

pub fn subview(self, region: ImageRegion) -> Result<Self, ImageError>

Creates a checked zero-copy planar subview.

Trait Implementations

impl<'a, T: Clone, const CHANNELS: usize> Clone for PlanarImageView<'a, T, CHANNELS>

fn clone(&self) -> PlanarImageView<'a, T, CHANNELS>

Returns a duplicate of the value.
