Implementations

impl<'a, P> ImageRef<'a, P>

pub fn new(shape: Shape, data: &'a [P]) -> Self

Trait Implementations

impl<'a, P: Clone> Clone for ImageRef<'a, P>

fn clone(&self) -> ImageRef<'a, P>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<P> Debug for ImageRef<'_, P>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<P> Image for ImageRef<'_, P>

type Pixel = P

Pixel type

fn shape(&self) -> Shape

Shape of the image

fn data(&self) -> &[Self::Pixel]

Data containing image

fn size(&self) -> Size

Image size

fn width(&self) -> usize

Image width

fn height(&self) -> usize

Image height

fn get(&self, row: usize, col: usize) -> Option<&Self::Pixel>

Get pixel at the specified row and column

fn view( &self, row_min: usize, row_max: usize, col_min: usize, col_max: usize, ) -> ImageRef<'_, Self::Pixel>

fn write(self, fmt: ImageWriteFormat, out: impl Write) -> Result<(), Error>

where Self::Pixel: Color, Self: Sized,

fn write_rgba<W>(&self, out: W) -> Result<(), Error>

where W: Write, Self::Pixel: Color, Self: Sized,
