# Mixbox for Rust
|
|
```ini
|
|
mixbox = "2.0.0" # add this line to your Cargo.toml
|
|
```
|
|
|
|
## Usage
|
|
```rust
|
|
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
|
|
```rust
|
|
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);
|
|
```
