Struct colorsys::Cmyk

pub struct Cmyk { /* fields omitted */ }

The CMYK color model.

Has cyan, magenta, yellow, key (0.0..100.0) and optional alpha channel (0.0..1.0).

Example

use colorsys::Cmyk;

let mut cmyk = Cmyk::new(33.1, 999.9, 11.0, 0.0, None);

assert_eq!(cmyk.cyan(), 33.1);
assert_eq!(cmyk.magenta(), 100.0);

cmyk.set_yellow(73.0);
assert_eq!(cmyk.yellow(), 73.0);

let doubled_cmyk = &cmyk + &cmyk;

let units: [f64;4] = doubled_cmyk.into();
assert_eq!(units, [66.2,100.0,100.0,0.0]);
