Struct palette::Luma

pub struct Luma<T: Float = f32> {
    pub luma: T,
}

Linear luminance.

Luma is a purely gray scale color space, which is included more for completeness than anything else, and represents how bright a color is perceived to be. It's basically the Y component of CIE XYZ. The lack of any form of hue representation limits the set of operations that can be performed on it.

Fields

luma: T

The lightness of the color. 0.0 is black and 1.0 is white.

Methods

impl<T: Float> Luma<T>

fn new(luma: T) -> Luma<T>

Linear luminance.

fn new_u8(luma: u8) -> Luma<T>

Linear luminance from an 8 bit value.
