Struct NearestResizeU8Plan 

pub struct NearestResizeU8Plan { /* private fields */ }

Reusable source-coordinate plan for packed u8 nearest-neighbor resize.

Execution uses the cached source indices for packed one- and three-channel images. Other channel counts and explicitly strided views use the generic resize path so the public fallback contract remains unchanged.

Implementations

impl NearestResizeU8Plan

pub fn new( input_width: usize, input_height: usize, output_width: usize, output_height: usize, ) -> Result<NearestResizeU8Plan, VisionError>

Builds a plan for the named input and output dimensions.

pub const fn input_dimensions(&self) -> (usize, usize)

Returns the planned input dimensions as (width, height).

pub const fn output_dimensions(&self) -> (usize, usize)

Returns the planned output dimensions as (width, height).

pub fn resize<const CHANNELS: usize>( &self, input: ImageView<'_, u8, CHANNELS>, ) -> Result<Image<u8, CHANNELS>, VisionError>

Resizes into a newly allocated packed image.

pub fn resize_into<const CHANNELS: usize>( &self, input: ImageView<'_, u8, CHANNELS>, output: ImageViewMut<'_, u8, CHANNELS>, ) -> Result<(), VisionError>

Resizes into caller-owned storage without allocating.

Trait Implementations

impl Clone for NearestResizeU8Plan

fn clone(&self) -> NearestResizeU8Plan

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NearestResizeU8Plan

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

Formats the value using the given formatter.

impl PartialEq for NearestResizeU8Plan

fn eq(&self, other: &NearestResizeU8Plan) -> 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.
