Methods

impl<T: Clone> RGBA<T>

fn new(r: T, g: T, b: T, a: T) -> RGBA<T>

fn iter(&self) -> Cloned<Iter<T>>

fn rgb(&self) -> RGB<T>

Copy RGB components out of the RGBA struct

fn rgb_mut(&mut self) -> &mut RGB<T>

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

Trait Implementations

impl<T: Copy, B> ComponentMap<RGBA<B>, T, B> for RGBA<T>

fn map<F>(&self, f: F) -> RGBA<B> where F: FnMut(T) -> B

Convenience function (equivalent of self.iter().map().collect()) for applying the same formula to every component.

impl<T> ComponentBytes<T> for RGBA<T>

fn as_slice(&self) -> &[T]

The components interpreted as an array, e.g. RGB gives 3-element slice. The red component is first.

fn as_mut_slice(&mut self) -> &mut [T]

fn as_bytes(&self) -> &[u8]

The components interpreted as raw bytes, in machine's native endian. Bytes of the red component are first.

fn from_iter<I: IntoIterator<Item=T>>(into_iter: I) -> RGBA<T>

Creates a value from an iterator.
