Methods
impl<T: Clone> RGBA<T>
[src]
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>
[src]
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. Read more
impl<T> ComponentBytes<T> for RGBA<T>
[src]
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.
