colorsys

A module for color conversion and mutation written in Rust. For now works with RGB(a), HSL(a) color models

Online documentation

What It Can Do

getters & setters

use colorsys::{Rgb, Hsl};

let rgb = Rgb::from((57.3, 12.7, 53.0));
let r = rgb.get_red();
// 57.3

let mut hsl = Hsl::default();
// Hsl { h: 0, s: 0, l: 0, a: 1 }
hsl.set_saturation(13.98);
hsl.set_saturation(305.71);
hsl.set_alpha(0.75);
// Hsl { h: 305.71, s: 13.98, l: 0, a: 0.75 }

conversion

See From/FromStr/Into traits implementation in docs for more info

use colorsys::{Rgb, Hsl};

let rbga_tuple = (57.3, 12.7, 53.0, 0.33);
let rgba = Rgb::from(&rbga_tuple);
let hsla: Hsl = rgba.as_ref().into();
// ~Hsl { h: 305.78, s: 63.71, l: 13.73, a: 0.33 }

let rgb_tuple: (f64,f64,f64) = Rgb::from(&hsla).into();
// ~(57.3, 12.7, 53.0)

let hsla_tuple: (f64,f64,f64,f64) = Hsl::from( Rgb::from(rgb_tuple) ).into();
// ~Hsl { h: 305.78, s: 63.71, l: 13.73, a: 1 }

let hex: String = rgba.to_hex_string();
// #390d35

modification

See ColorTransform/Add*/Sub*.. traits in docs for more

use colorsys::{Hsl, Rgb, ColorTransform,ColorAlpha, SaturationInSpace};

let mut rgb: Rgb = (245.0,152.0,53.0).into();

rgb.lighten(20.1);
// ~Rgb { r: 249.83, g: 201.80, b: 150.67 }

rgb.opacify(-0.7);
rgb.saturate( SaturationInSpace::Hsl(-35.7) );
// ~Rgb { r: 230.29, g: 201.19, b: 170.21, a: 0.3 }

rgb.grayscale_simple();
// ~Rgb { r: 200.255, g: 200.255, b: 200.255, a: 0.3 }


let mut hsl = Hsl::from(&rgb);
hsl.opacify(1.0);
// ~Hsl { h: 0.0, s: 0.0, l: 78.53 }

hsl.adjust_hue(231.99);
hsl.saturate(SaturationInSpace::Hsl(55.7));

let mut rgb2: Rgb = hsl.as_ref().into();
// ~Rgb { r: 169.76, g: 177.9, b: 230.75}

rgb2.invert();
// ~Rgb { r: 85.24, g: 77.09, b: 24.25 }

let rgb3 = rgb - rgb2;
// ~Rgb { r: 115.01, g: 123.16, b: 176.0 }

let hsl2 = hsl + rgb3.into();
// ~Hsl { h: 0.0, s: 83.55, l: 100.0 }

parsing from string & css string representation

use colorsys::{Hsl, Rgb};
use std::str::FromStr;

let s = "rgb(177, 255, 176)";

let rgb: Rgb = s.parse().unwrap();

rgb.to_css_string();
// String: "rgb(177,255,176)"

rgb.to_hex_string();
// #b1ffb0

Hsl::from_str("hsl(168, 52%, 42%)").unwrap().to_css_string();
// String: hsl(168,52%,42%)

Color unit ranges

All color units is f64. Here are their ranges:

• red - 0.0 .. 255.0
• green - 0.0 .. 255.0
• blue - 0.0 .. 255.0
• hue - 0.0 .. 360.0
• saturation - 0.0 .. 100.0
• lightness - 0.0 .. 100.0
• alpha - 0.0 .. 1.0

If you specify a value that does not fit within these ranges, they are replaced with a minimum or maximum value.

Enjoy using!
