Implementations

impl<T: Clone, const C: usize> SubImage<&[T], C>

pub fn own(&self) -> Image<Box<[T]>, C>

Clones this SubImage into its own Image

impl<W, const C: usize> SubImage<W, C>

pub unsafe fn pixel<U: Copy>(&self, x: u32, y: u32) -> [U; C]

where W: AsRef<[U]>,

Get a pixel.

Safety

this pixel must be in bounds.

pub unsafe fn pixel_mut<U: Copy>(&mut self, x: u32, y: u32) -> &mut [U]

where W: AsMut<[U]> + AsRef<[U]>,

Get a pixel, mutably.

Safety

this pixel must be in bounds.

Trait Implementations

impl<T: Clone, const CHANNELS: usize> Clone for SubImage<T, CHANNELS>

fn clone(&self) -> SubImage<T, CHANNELS>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Clone, const N: usize> Copy for SubImage<T, N>

where Image<T, N>: Copy,
