Type Alias Rgba 

pub type Rgba<S = Srgb, T = f32> = Alpha<Rgb<S, T>, T>;

Generic RGB with an alpha component. See the Rgba implementation in Alpha.

Aliased Type

#[repr(C)]
pub struct Rgba<S = Srgb, T = f32> {
    pub color: Rgb<S, T>,
    pub alpha: T,
}

Fields

color: Rgb<S, T>

The color.

alpha: T

The transparency component. 0.0 (or 0u8) is fully transparent and 1.0 (or 255u8) is fully opaque.

Trait Implementations

impl ColorExt for Rgba

fn blend(&self, other: &Self) -> Self

Composites other over this color with Porter–Duff source-over.

fn fade_out(&mut self, factor: f32)

Reduces the alpha of this color in place by factor.

fn opacity(&self, factor: f32) -> Self

Returns a copy of this color with its alpha multiplied by factor.

impl Interpolate for Rgba

fn interpolate(from: Self, to: Self, phase: f32) -> Self

Returns the value at phase, where 0.0 is from and 1.0 is to.

impl Lerp for Rgba

fn lerp(&self, to: &Self, delta: f32) -> Self

Returns the value delta of the way from self to to.

impl RasterColorExt for Rgba

fn quantize_raster_color(self) -> Rgba8

Clamps and rounds each channel to the nearest byte.
