Struct ColorGradient 

pub struct ColorGradient { /* private fields */ }

Multi-stop color gradient.

Implementations

impl ColorGradient

pub fn new() -> Self

pub fn add_stop(&mut self, stop: ColorStop)

Add a color stop (will be kept sorted by t).

pub fn clear(&mut self)

Clear all stops.

pub fn stop_count(&self) -> usize

Number of stops.

pub fn sample(&self, t: f32) -> (f32, f32, f32, f32)

Sample the gradient at t in [0, 1]. Returns (r, g, b, a).

pub fn sample_arr(&self, t: f32) -> [f32; 4]

Sample and return as [f32; 4] array.

pub fn two_stop(c0: ColorStop, c1: ColorStop) -> Self

Build a simple two-stop gradient.
