Struct GrayFrame 

pub struct GrayFrame {
    pub width: usize,
    pub height: usize,
    pub data: Vec<u8>,
}

A grayscale image used as input for perceptual hashing.

Pixels are stored in row-major order with values in [0, 255].

Fields

width: usize

Image width in pixels.

height: usize

Image height in pixels.

data: Vec<u8>

Row-major grayscale pixel values.

Implementations

impl GrayFrame

pub fn new(width: usize, height: usize, data: Vec<u8>) -> DedupResult<Self>

Create a new frame from raw data.

Errors

Returns an error if data.len() != width * height.

pub fn from_rgb( width: usize, height: usize, rgb: &[u8], channels: usize, ) -> DedupResult<Self>

Create from an RGB(A) buffer.

Uses ITU-R BT.601 luma: Y = 0.299R + 0.587G + 0.114B.

Errors

Returns an error if buffer length doesn’t match width * height * channels.

pub fn resize(&self, new_width: usize, new_height: usize) -> Self

Nearest-neighbour resize to new_width × new_height.

Trait Implementations

impl Clone for GrayFrame

fn clone(&self) -> GrayFrame

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GrayFrame

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

Formats the value using the given formatter.
