[−][src]Trait cichlid::color_util::RainbowFill

pub trait RainbowFill: Sized {
    fn rainbow_fill_with_sat_val(
        self, 
        start_hue: u8, 
        hue_delta: u16, 
        sat: u8,

    );

    fn rainbow_fill(self, start_hue: u8, hue_delta: u16) { ... }
}

Fills an iterable object with a rainbow hue of a desired step size.

Step sizes is a u16. The Most significant byte of each integer is used to represent the full number of hues to increment between each iterated value, while the second (LSB) byte is added as a fractional component.

For example, if one desires to change a single hue between each element, the hue_delta should be set to 0x0100. If a hue is desired to change every 256 elements, then the hue_delta should be 0x0001.
