Struct webrender_api::PremultipliedColorF

#[repr(C)]
pub struct PremultipliedColorF {
    pub r: f32,
    pub g: f32,
    pub b: f32,
    pub a: f32,
}

Represents pre-multiplied RGBA colors with floating point numbers.

All components must be between 0.0 and 1.0. An alpha value of 1.0 is opaque while 0.0 is fully transparent.

In premultiplied colors transitions to transparent always look "nice" therefore they are used in CSS gradients.

Fields

r: f32

g: f32

b: f32

a: f32
