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).
