Struct palette::RgbHue [−] [src]

pub struct RgbHue<T: Float = f32>(_);

A hue type for the RGB family of color spaces.

It's measured in degrees and uses the three additive primaries red, green and blue.

The hue is a circular type, where 0 and 360 is the same, and it's normalized to (-180, 180] when it's converted to a linear number (like f32). This makes many calculations easier, but may also have some surprising effects if it's expected to act as a linear number.

Methods

impl<T: Float> RgbHue<T>
[src]

fn from_radians(radians: T) -> RgbHue<T>

Create a new hue from radians, instead of degrees.

fn to_degrees(self) -> T

Get the hue as degrees, in the range (-180, 180].

fn to_radians(self) -> T

Convert the hue to radians, in the range (-π, π].

fn to_positive_degrees(self) -> T

Convert the hue to positive degrees, in the range [0, 360).

fn to_positive_radians(self) -> T

Convert the hue to positive radians, in the range [0, 2π).
