Struct Luma

#[repr(C)]
pub struct Luma<S = Srgb, T = f32> {
    pub luma: T,
    pub standard: PhantomData<S>,
}

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.

standard: PhantomData<S>

The kind of RGB standard. sRGB is the default.

Implementations

impl<S, T> Luma<S, T>

pub const fn new(luma: T) -> Luma<S, T>

impl<S> Luma<S, u8>

pub fn into_u16<O>(self) -> u16

where O: ComponentOrder<Lumaa<S, u8>, u16>,

Convert to a packed u16 with with specifiable component order.

use palette::{luma, SrgbLuma};

let integer = SrgbLuma::new(96u8).into_u16::<luma::channels::La>();
assert_eq!(0x60FF, integer);

It’s also possible to use From and Into, which defaults to the 0xAALL component order:

use palette::SrgbLuma;

let integer = u16::from(SrgbLuma::new(96u8));
assert_eq!(0xFF60, integer);

See Packed for more details.
