Struct Chromaticity

#[repr(C)]
pub struct Chromaticity {
    pub x: f32,
    pub y: f32,
}

Fields

x: f32

y: f32

Implementations

impl Chromaticity

pub const D65: Chromaticity

pub const D50: Chromaticity

pub const fn new(x: f32, y: f32) -> Self

pub const fn to_xyz(&self) -> Xyz

Converts this chromaticity (x, y) to a tristimulus Xyz value, normalized such that y = 1.0.

pub const fn to_scaled_xyzd(&self) -> Xyzd

Get the color representation with component sum 1.

In contrast to the XYZ representation defined through setting Y to a known value (such as 1 in Self::to_xyz) this representation can be uniquely derived from the xy coordinates with no ambiguities. It is scaled from the original XYZ color by diving by X + Y + Z. Note that, in particular, this method is well-defined even if the original color had pure chromamatic information with no luminance (Y = 0) and will preserve that information, whereas Self::to_xyz is ill-defined and returns an incorrect value.
