[−][src]Struct webrender_api::ColorF
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

pub fn new(r: f32, g: f32, b: f32, a: f32) -> Self
[src]
Constructs a new ColorF
from its components.
pub fn scale_rgb(&self, scale: f32) -> Self
[src]
Multiply the RGB channels (but not alpha) with a given factor.
pub fn scale_alpha(&self, scale: f32) -> Self
[src]
pub fn to_array(&self) -> [f32; 4]
[src]
pub fn premultiplied(&self) -> PremultipliedColorF
[src]
Multiply the RGB components with the alpha channel.
