pub trait Delta: Into<LabValue> {
    fn delta<L>(self, other: L, method: DEMethod) -> DeltaE
        L: Into<LabValue>
, { ... } }
Expand description

Trait to determine color difference between various types. As long as the type can be converted to Lab, we can calculate DeltaE.

Provided Methods

Calculate DeltaE between 2 types

use deltae::*;

let lch = LchValue::new(60.3, 89.2, 270.0).unwrap();
let xyz = XyzValue::new(0.347, 0.912, 0.446).unwrap();
let de  =, DE1976);
assert_eq!(de, 180.18364);
