colorgram-rust

---

colorgram-rust is a rust program that lets you extract colors from image. It is a port of colorgram.py (which is itself a port of colorgram.js, so it's basically a port of a port =D)

Why? Well, it's ~25 times faster than colorgram.py (9 ms vs 225 ms for test.png) on my laptop

Installation as CLI utility

cargo install colorgram

Adding to your rust project

[dependencies]
colorgram = "0.1.0"

Usage Example (code from main.rs)

use colorgram::extract;
use std::fs;

fn main() -> Result<(), Box<dyn std::error::Error>> {
    let buf = fs::read("image.jpg")?;
    let colors = extract(&buf, 5)?;

    for color in colors {
        println!("Color: {}, Weight: {:.2}%", color.rgb, color.proportion * 100.0);
    }
    Ok(())
}
