A Rust implementation of HSLuv.

Demo

Demo link: http://www.hsluv.org/syntax/#006925

Installation

Add this line to your application's Cargo.toml:

toml [dependencies] hsluv = { git = "https://github.com/dvdplm/hsluv-rust" }

Usage

• hue is a 64bit float between 0 and 360
• saturation is a 64bit float between 0 and 100
• lightness is a 64bit float between 0 and 100
• hex is the hexadecimal format of the color
• red is a 64bit float between 0 and 1
• green is a 64bit float between 0 and 1
• blue is a 64bit float between 0 and 1

```rust extern crate hsluv;

use hsluv::*;

fn main() { let hex = "#ab3912"; let hsluv = hextohsluv(hex); let rgb = hsluvtorgb(hsluv);

println!("Convert HEX {:?} to HSLUV: {:?}", hex, hsluv); println!("Convert HSLUV {:?} to RGB: {:?}", hsluv, rgb); println!("Convert RGB {:?} to HEX: {:?}", rgb, rgbtohex(rgb)); } ```

All API calls take and return a 3-tuple of 64bit floats, (f64, f64, f64) except the *_to_hex() functions: hsluv_to_hex(), hpluv_to_hex(), rgb_to_hex() which return String.

hsluv::hsluvtohex((hue, saturation, lightness)) -> color as a hex string

rust hsluv::hsluv_to_hex((12.177, 100.0, 53.23)) // => #ff0000

hsluv::hsluvtorgb((hue, saturation, lightness)) -> color as rgb

rust hsluv::hsluv_to_rgb(12.177, 100.0, 53.23) // => (0.9998643703868711, 0.00000000000006849859221502719, 0.000008791283550555612)

hsluv::hextohsluv(hex) -> list of floats as defined above

```rust hsluv::hextohsluv("#ff0000") // => (12.177050630061776, 100.0000000000022, 53.23711559542933)

```

hsluv::rgbtohsluv(rgb) -> list of floats as defined above

rust hsluv::rgb_to_hsluv((0.99, 6.84e-14, 8.79e-16)) // => (12.17705063006216, 100.00000000000209, 52.711595266911985)

For HPLuv (the pastel variant), use:

• hpluv_to_hex
• hpluv_to_rgb
• hex_to_hpluv
• rgb_to_hpluv
