Implementations

impl<T: Copy> Bgra<T>

pub const fn new_bgra(blue: T, green: T, red: T, alpha: T) -> Self

Creates a new Bgra pixel type from its components.

Alternatively, you can use struct literal syntax to create the new pixel type:

use rgb::Bgra;

let pixel = Bgra {b : blue, g : green, r : red, a : alpha};

impl<T> Bgra<T>

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

👎Deprecated: This function has a misleading order of arguments. Use BGRA{} literal instead

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

impl<T, A> Bgra<T, A>

let r = rgb::BGRA::<u8,u16>::zeroed();

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

👎Deprecated: This function has a misleading order of arguments. Use BGRA{} literal instead

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

impl<T, A> Bgra<T, A>

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

👎Deprecated: This function will change. Use bgr_mut()

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

pub fn bgr_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: Clone, A> Bgra<T, A>

pub fn rgb(&self) -> BGR<T>

👎Deprecated: This function will change. Use bgr()

Copy RGB components out of the RGBA struct

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

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

Iterate over all components (length=4)

impl<T: Clone, A> Bgra<T, A>

pub fn bgr(&self) -> BGR<T>

pub fn map_rgb<F, U, B>(&self, f: F) -> BGRA<U, B>

where F: FnMut(T) -> U, U: Clone, B: From<A> + Clone,

👎Deprecated: Renamed to map_colors()

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

pub fn with_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.
