Struct Chromaticity 

pub struct Chromaticity {
    pub x: f32,
    pub y: f32,
}

CIE xy chromaticity, specifying a color in the XYZ color space, but not its luminosity.

An absolute color can be specified by adding a luminosity coordinate Y as in xyY. An XYZ color can be calculated from xyY as follows.

X = Y/y * x
Y = Y
Z = Y/y * (1 - x - y)

Fields

x: f32

The x-coordinate of the CIE xy chromaticity.

y: f32

The y-coordinate of the CIE xy chromaticity.

Implementations

impl Chromaticity

pub const D65: Chromaticity

The CIE D65 white point under the standard 2° observer.

This is a common white point for color spaces targeting monitors.

The white point’s chromaticities are truncated to four digits here, as specified by the CSS Color 4 specification, and following most color spaces using this white point.

pub const D50: Chromaticity

The CIE D50 white point under the standard 2° observer.

The white point’s chromaticities are truncated to four digits here, as specified by the CSS Color 4 specification, and following most color spaces using this white point.

pub const ACES: Chromaticity

The ACES white point.

This is the reference white of ACEScg and ACES2065-1. The white point is near the D60 white point under the standard 2° observer.

Trait Implementations

impl Clone for Chromaticity

fn clone(&self) -> Chromaticity

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Chromaticity

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl PartialEq for Chromaticity

fn eq(&self, other: &Chromaticity) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
