Struct bayer::RasterMut

pub struct RasterMut<'a> { /* fields omitted */ }

Mutable raster structure.

Methods

impl<'a> RasterMut<'a>

fn new(w: usize, h: usize, depth: RasterDepth, buf: &'a mut [u8]) -> Self

Allocate a new raster for the given destination buffer slice.

Examples

const IMG_W: usize = 320;
const IMG_H: usize = 200;
let mut buf = [0; 3 * IMG_W * IMG_H];

bayer::RasterMut::new(
        IMG_W, IMG_H, bayer::RasterDepth::Depth8,
        &mut buf);

fn with_offset(
    x: usize,
    y: usize,
    w: usize,
    h: usize,
    stride: usize,
    depth: RasterDepth,
    buf: &'a mut [u8]
) -> Self

Allocate a new raster for the given destination buffer slice. Stride is in number of bytes.

Examples

const IMG_W: usize = 320;
const IMG_H: usize = 200;
let mut buf = [0; 3 * IMG_W * IMG_H];

bayer::RasterMut::with_offset(
        0, 0, IMG_W, IMG_H, 3 * IMG_W, bayer::RasterDepth::Depth8,
        &mut buf);

fn borrow_row_u8_mut(&mut self, y: usize) -> &mut [u8]

Borrow a mutable u8 row slice.

Panics

Panics if the raster is not 8-bpp.

fn borrow_row_u16_mut(&mut self, y: usize) -> &mut [u16]

Borrow a mutable u16 row slice.

Panics

Panics if the raster is not 16-bpp.
