Struct azul_webrender_api::ColorF

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

Represents RGBA screen 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.

Fields

r: f32

g: f32

b: f32

a: f32

Implementations

impl ColorF

pub const BLACK: ColorF

pub const TRANSPARENT: ColorF

pub const WHITE: ColorF

pub fn new(r: f32, g: f32, b: f32, a: f32) -> Self

Constructs a new ColorF from its components.

pub fn scale_rgb(&self, scale: f32) -> Self

Multiply the RGB channels (but not alpha) with a given factor.

pub fn scale_alpha(&self, scale: f32) -> Self

pub fn to_array(&self) -> [f32; 4]

pub fn premultiplied(&self) -> PremultipliedColorF

Multiply the RGB components with the alpha channel.

Trait Implementations
