Trait colorsys::ColorTransform

pub trait ColorTransform {
    fn lighten(&mut self, amt: f64);
    fn saturate(&mut self, sat: SaturationInSpace);
    fn adjust_hue(&mut self, hue: f64);
    fn grayscale_simple(&mut self);
    fn invert(&mut self);
}

A collection of methods to some special modification of color. Some methods (like saturate, lighten, etc.) requires (inside implementation) converting to another color space and vice versa.

Required Methods

fn lighten(&mut self, amt: f64)

Makes color lighter or (if amt is negative) darker. Amt is percent - 1..100 to make color lighter; -100..-1 for blacking-out

fn saturate(&mut self, sat: SaturationInSpace)

Saturate/desaturate color. Value is percent: -100..100. You need specify in what color space you want to increase/decrease saturation.

fn adjust_hue(&mut self, hue: f64)

increase/decrease color tone. Value is degree - -360..360.

fn grayscale_simple(&mut self)

Brings color to a shade of gray. For more specific grayscale methods see Rgb.grayscale

fn invert(&mut self)

Just inverts color
