Mixbox for Rust

mixbox = "2.0.0"  # add this line to your Cargo.toml

Usage

fn main() {
    let rgb1 = [0, 33, 133];  // blue
    let rgb2 = [252, 211, 0]; // yellow
    let t = 0.5;              // mixing ratio

    let [r, g, b] = mixbox::lerp(&rgb1, &rgb2, t);

    println!("{} {} {}", r, g, b);
}

Mixing Multiple Colors

let z1 = mixbox::rgb_to_latent(&rgb1);
let z2 = mixbox::rgb_to_latent(&rgb2);
let z3 = mixbox::rgb_to_latent(&rgb3);

let mut z_mix = [0.0; mixbox::LATENT_SIZE];

for i in 0..z_mix.len() {     // mix together:
    z_mix[i] = 0.3*z1[i] +    // 30% of rgb1
               0.6*z2[i] +    // 60% of rgb2
               0.1*z3[i];     // 10% of rgb3
}

let rgb_mix = mixbox::latent_to_rgb(&z_mix);
