Struct RgbaSliceU8 

pub struct RgbaSliceU8<'a> { /* private fields */ }

Container for a slice of contiguous [R G B A R G B A ...] data.

Implementations

impl<'a> RgbaSliceU8<'a>

pub fn new(data: &'a [u8], dimensions: (usize, usize)) -> Self

Creates a new instance given the byte slice and dimensions.

Panics

May panic if the given sizes are not multiples of 2, or if the slice length mismatches the given dimensions.

Trait Implementations

impl<'a> Clone for RgbaSliceU8<'a>

fn clone(&self) -> RgbaSliceU8<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for RgbaSliceU8<'a>

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

Formats the value using the given formatter.

impl<'a> RGBSource for RgbaSliceU8<'a>

fn dimensions(&self) -> (usize, usize)

Returns the underlying image size as an usize tuple (w, h).

fn pixel_f32(&self, x: usize, y: usize) -> (f32, f32, f32)

Extract the pixel value at the specified location. Pixel values are expected to be floats in the range [0, 255] (u8 represented as f32).

fn dimensions_i32(&self) -> (i32, i32)

Returns the underlying image size as an i32 tuple (w, h).
