Colorous
This crate provides a collection of sequential, diverging and categorical color
schemes ported from d3-scale-chromatic. Each color scheme may be sampled using
either a rational index i/n
or a continuous float 0 ≤ t ≤ 1
.
pub fn eval_rational(&self, i: usize, n: usize) -> Color
pub fn eval_continuous(&self, t: f64) -> Color
Example
let gradient = colorous::VIRIDIS;
for i in 0..100 {
println!("{:x}", gradient.eval_rational(i, 100));
}
