Methods

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

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
