Struct ImageBuf 

pub struct ImageBuf { /* private fields */ }

Structured image buffer with metadata.

Stores pixels in row-major order: data[y * width * channels + x * channels + c].

Implementations

impl ImageBuf

pub fn new( data: Vec<f32>, width: usize, height: usize, channels: usize, ) -> Result<Self, ImageError>

Create a new image buffer.

Errors

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

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

Create a zero-filled image buffer.

pub fn width(&self) -> usize

Image width in pixels.

pub fn height(&self) -> usize

Image height in pixels.

pub fn channels(&self) -> usize

Number of channels (1=gray, 3=RGB, 4=RGBA).

pub fn dtype(&self) -> DType

Pixel data type.

pub fn data(&self) -> &[f32]

Raw pixel data as slice.

pub fn data_mut(&mut self) -> &mut [f32]

Mutable raw pixel data.

pub fn len(&self) -> usize

Total number of elements (width * height * channels).

pub fn is_empty(&self) -> bool

Returns true if the buffer is empty.

pub fn channel(&self, channel: usize) -> Result<Self, ImageError>

Extract a single channel as a new grayscale ImageBuf.

Errors

Returns error if channel >= self.channels().
