Implementations

impl<T> BGRA<T>[−]

pub const fn new(r: T, g: T, b: T, a: T) -> Self[−]

Convenience function for creating a new pixel The order of arguments is R,G,B,A

impl<T, A> BGRA<T, A>[−]

pub const fn new_alpha(r: T, g: T, b: T, a: A) -> Self[−]

Convenience function for creating a new pixel The order of arguments is R,G,B,A

impl<T: Clone> BGRA<T>[−]

pub fn iter(&self) -> Cloned<Iter<'_, T>>[−]

Iterate over all components (length=4)

impl<T: Clone, A> BGRA<T, A>[−]

pub fn rgb(&self) -> BGR<T>[−]

Copy RGB components out of the RGBA struct

Note: you can use .into() to convert between other types

impl<T, A> BGRA<T, A>[−]

pub fn rgb_mut(&mut self) -> &mut BGR<T>[−]

Provide a mutable view of only RGB components (leaving out alpha). Useful to change color without changing opacity.

impl<T: Copy, A: Clone> BGRA<T, A>[−]

pub fn map_rgb<F, U, B>(&self, f: F) -> BGRA<U, B> where
    F: FnMut(T) -> U,
    U: Clone,
    B: From<A> + Clone, [−]

Create new RGBA with the same alpha value, but different RGB values

pub fn alpha(&self, a: A) -> Self[−]

Create a new RGBA with the new alpha value, but same RGB values

pub fn map_alpha<F, B>(&self, f: F) -> BGRA<T, B> where
    F: FnOnce(A) -> B, [−]

Create a new RGBA with a new alpha value created by the callback. Allows changing of the type used for the alpha channel.

Trait Implementations

impl<T> AsPixels<BGRA<T, T>> for [T][+]

[+] Show hidden undocumented items

fn as_pixels(&self) -> &[BGRA<T>][−]

Reinterpret the slice as a read-only/shared slice of pixels. Multiple consecutive elements in the slice are intepreted as a single pixel (depending on format, e.g. 3 for RGB, 4 for RGBA).

fn as_pixels_mut(&mut self) -> &mut [BGRA<T>][−]

Reinterpret the slice as a mutable/exclusive slice of pixels. Multiple consecutive elements in the slice are intepreted as a single pixel (depending on format, e.g. 3 for RGB, 4 for RGBA).
