Implementations

impl<T: Copy> Argb<T>

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

Creates a new Argb pixel type from its components.

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

use rgb::Argb;

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

impl<T> Argb<T>

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

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