A Rust library for converting between color spaces and comparing colors, ported from https://github.com/berendeanicolae/ColorSpace.
WARNING: This has not been extensively tested yet, it's simply been ported. There could still be some errors in my ported code for certain conversions. Until version 1.0.0, which will be stable, use at your own discretion.
You can convert between any supported color spaces using the from trait method:
rust
let rgb = Rgb::new(0.0, 255.0, 0.0);
let hsv = Hsv::from(rgb);
assert_eq!(hsv, Hsv::new(120.0, 1.0, 1.0));
You can also do this generically with the from_color method:
rust
let rgb = Rgb::new(0.0, 0.0, 255.0);
let hsv = Hsv::from_color(&rgb);
assert_eq!(hsv, Hsv::new(240.0, 1.0, 1.0));
You can compare colors by using the compare_* methods:
rust
let rgb = Rgb::new(255.0, 0.0, 0.0);
let hsv = Hsv::new(0.0, 1.0, 1.0);
let diff = rgb.compare_cie2000(&hsv);
assert_eq!(diff, 0.0);
// these two colors are the same, so the difference is zero
