deltae

Library

A rust library for interacting with and manipulating Lab and Lch colors and calculating DeltaE (color difference).

Check out the documentation here: Rust API Documentation

...or compile it yourself:

sh cargo doc --open

Examples

```rust extern crate deltae; use deltae::{DeltaE, DEMethod::DE2000}; use deltae::color::LabValue;

fn main() { let lab0 = LabValue::from("89.73, 1.88, -6.96").unwrap(); let lab1 = LabValue { l: 95.08, a: -0.17, b: -10.81, };

println!("{}", lab0); // [L:89.73, a:1.88, b:-6.96]

let de0 = DeltaE::new(&lab0, &lab1, DE2000).round_to(4);

println!("{}: {}", de0.method, de0.value); // DE2000: 5.3169

let de1 = DeltaE::from(
    "89.73, 1.88, -6.96",
    "95.08, -0.17, -10.81",
    "DE2000"
).unwrap();

assert_eq!(de0, de1.round_to(4));

let lch0 = lab0.to_lch();
let lab2 = lch0.to_lab();

println!("{}", lch0); // [L:89.73, c:7.2094, h:285.1157]

assert_eq!(lab0.round_to(4), lab2.round_to(4));

} ```

Binary

The binary included with this library is a command line application that calculates Delta E between to Lab colors.

Usage

sh deltae [--method=<DE Method>] <L,a,b,> <L,a,b>

Example

sh deltae --method=de1976 "89.73, 1.88, -6.96" "95.08, -0.17, -10.81"

Install

sh git clone https://github.com/ryanobeirne/deltae cd deltae cargo install --example=deltae --path=. --force

Notes

Calculates DE2000, DE1994 (Graphic Arts and Textiles), DECMC(1:1), DECMC(2:1), and DE1976. The Default is DE2000.
