Struct OwnedMatView 

pub struct OwnedMatView { /* private fields */ }

Pure-Rust owned mat-view for use in tests and pure-Rust pipelines.

Implementations

impl OwnedMatView

pub fn new( width: u32, height: u32, pixel_format: PixelFormat, data: Vec<u8>, ) -> Result<OwnedMatView, ImageOpsError>

Build a new owned mat-view. Fails if data.len() does not match width * height * pixel_format.channels().

pub fn zeros(width: u32, height: u32, pixel_format: PixelFormat) -> OwnedMatView

Allocate a zero-filled mat-view of the given shape and format.

pub fn into_data(self) -> Vec<u8>

Consume the view and return the backing buffer.

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

Mutable access to the backing buffer.
