colorsys

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

Online documentation

What It Can Do

getters & setters

```Rust 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.setsaturation(13.98); hsl.setsaturation(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 ```Rust use colorsys::{Rgb, Hsl};

let rbgatuple = (57.3, 12.7, 53.0, 0.33); let rgba = Rgb::from(&rbgatuple); 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 hslatuple: (f64,f64,f64,f64) = Hsl::from( Rgb::from(rgbtuple) ).into(); // ~Hsl { h: 305.78, s: 63.71, l: 13.73, a: 1 }

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

// From/Into let rgb1 = Rgb::fromhexstr("37ea4c").unwrap();

let rgb2 = Rgb::from( Into::<[f32; 4]>::into(Rgb::from( Into::<[u8; 4]>::into( Rgb::from( Into::<(i32,i32,i32)>::into( Rgb::from( Into::<[i64; 3]>::into(&rgb1) ) ) ) ) )) );

assert_eq!(rgb1, rgb2);

```

modification

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

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

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

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

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

rgb.tohexstring(); // #b1ffb0

Hsl::fromstr("hsl(168, 52%, 42%)").unwrap().tocss_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!
