Struct nannou::color::Gradient[][src]

pub struct Gradient<C>(_)
    C: Mix + Clone

A linear interpolation between colors.

It’s used to smoothly transition between a series of colors, that can be either evenly spaced or have customized positions. The gradient is continuous between the control points, but it’s possible to iterate over a number of evenly spaced points using the take method. Any point outside the domain of the gradient will have the same color as the closest control point.


impl<C> Gradient<C> where
    C: Mix + Clone

pub fn new<I>(colors: I) -> Gradient<C> where
    I: IntoIterator<Item = C>, 

Create a gradient of evenly spaced colors with the domain [0.0, 1.0]. There must be at least one color.

pub fn with_domain(colors: Vec<(<C as Mix>::Scalar, C), Global>) -> Gradient<C>[src]

Create a gradient of colors with custom spacing and domain. There must be at least one color and they are expected to be ordered by their position value.

pub fn get(&self, i: <C as Mix>::Scalar) -> C[src]

Get a color from the gradient. The color of the closest control point will be returned if i is outside the domain.

pub fn take(&self, n: usize) -> Take<'_, C>

Notable traits for Take<'a, C>

impl<'a, C> Iterator for Take<'a, C> where
    C: Mix + Clone
type Item = C;

Take n evenly spaced colors from the gradient, as an iterator.

pub fn slice<R>(&self, range: R) -> Slice<'_, C> where
    R: Into<Range<<C as Mix>::Scalar>>, 

Slice this gradient to limit its domain.

pub fn domain(&self) -> (<C as Mix>::Scalar, <C as Mix>::Scalar)[src]

Get the limits of this gradient’s domain.
