Struct ImageU8 

pub struct ImageU8 { /* private fields */ }

HWC u8 image wrapper: (width, height, channels, Vec<u8>). Simple u8 image wrapper (HWC layout, row-major).

Implementations

impl ImageU8

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

Creates a new image from raw bytes. Returns None if length doesn’t match.

pub fn zeros(height: usize, width: usize, channels: usize) -> Self

Creates a zero-filled image.

pub fn data(&self) -> &[u8]

pub fn data_mut(&mut self) -> &mut [u8]

pub fn height(&self) -> usize

pub fn width(&self) -> usize

pub fn channels(&self) -> usize

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn from_tensor(tensor: &Tensor) -> Option<Self>

Convert from f32 Tensor [H,W,C] to u8 image (clamp to [0,255]).

pub fn to_tensor(&self) -> Tensor

Convert to f32 Tensor [H,W,C] with values in [0,1].
