colors_transform

A module for color conversion and mutation written in Rust.

For now you can work with four color representation options: Rgb, Rgba, Hsl, Hsla. Each of them has a variety of methods to modify and convert. See the Color trait they implement. There are also a couple of methods for hex string color.

All values are given as f32 for more accurate calculations.

What It Can Do

getters & setters

use colors_transform::{Rgb, Color};
let rgb = Rgb::from_tuple((57.3, 12.7, 53.0));
// where tuple is ($red, $green, $blue)

let modified = rgb
  .set_red(245.0) // Rgb { r: 245.0, g: 152.0, b: 53.0 }
  .set_green(152.0) // Rgb { r: 245.0, g: 152.0, b: 53.0 }
  .set_hue(279.0); // Rgb { r: 177.80003, g: 53.00001, b: 245.0 }

let saturation = modified.get_saturation(); // 63.71429
let blue = modified.get_blue(); // 53.00001

conversion

let hex_color = Hsl::from_tuple((315.9, 99.7, 50.0))
// where tuple is ($hue, $saturation, $lightness)
  .to_rgb() // ~Rgb { r: 254.6, g: 0.38, b: 187.24 }
  .set_saturation(33.3) // ~Rgb { r: 169.9, g: 85.04, b: 147.45 }
  .to_hsla() // Hsla { h: 315.9, s: 33.3, l: 50.0 alpha: 1.0 }
  .set_alpha(0.47) // Hsla { h: 315.9, s: 99.7, l: 50.0 alpha: 0.47 }
  .to_rgb() // Rgb { r: 169.95749, g: 85.0425, b: 147.45502 }
  .to_css_hex_string(); // #aa5593

modification

let rgb = Rgb::from_tuple((245.0,152.0,53.0))
  .lighten(21.0) // Rgb { r: 250.05188, g: 204.03442, b: 155.04813 }
  .saturate( 3.9999 ); // Rgb { r: 252.14981, g: 204.1, b: 152.9502 }
// TODO: grayscale, invert and other

parsing from string & css string representation

let hsla: Hsla = "hsla(359,12%,71,0.3)".parse().unwrap();
// Hsla { h: 359.0, s: 12.0, l: 71.0 alpha: 0.3 }

let rgb1 = "rgb(12,13,14)"
  .parse::<Rgb>()
  .unwrap()
  .adjust_color( RgbColor::Green, 139.7 );
// Rgb { r: 12.0, g: 152.7, b: 14.0 }

let rgb2 = Rgb::from_hex_str("#fc0").unwrap();
// Rgb { r: 255.0, g: 204.0, b: 0.0 }

let rgb_str = rgb1.to_css_string();
// rgb(12,153,14)

let hsla_str = rgb2.to_hsla().to_css_string();
// "hsla(48,100%,50%,1)"

As you see it is completely chainable.

Color unit ranges

All color units is f32. 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!
