Struct palette::LabHue
[−]
[src]
pub struct LabHue<T: Float = f32>(_);
A hue type for the CIE L*a*b* family of color spaces.
It's measured in degrees and it's based on the four physiological elementary colors red, yellow, green and blue. This makes it different from the hue of RGB based color spaces.
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> LabHue<T>
[src]
fn from_radians(radians: T) -> LabHue<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)
.
