Struct epaint::Hsva

source ·
pub struct Hsva {
    pub h: f32,
    pub s: f32,
    pub v: f32,
    pub a: f32,
}
Expand description

Hue, saturation, value, alpha. All in the range [0, 1]. No premultiplied alpha.

Fields§

§h: f32

hue 0-1

§s: f32

saturation 0-1

§v: f32

value 0-1

§a: f32

alpha 0-1. A negative value signifies an additive color (and alpha is ignored).
