Tool to create fingerprint images?

Is there some tool to create fingerprint images like on acoustid.org, to compare submitted fingerprints to local files?

For reference, the code that creates the images on the website is renderFingerprintData here:

Wrote a little Rust program to turn the output of fpcalc into an image that matches those on AcoustID.org (works for me on Linux).

src/main.rs:

use std::env;
use std::process::Command;

fn main() {
    let args: Vec<String> = env::args().collect();
    let file = &args[1];
    let output = Command::new("/usr/bin/fpcalc")
        .arg("-raw")
        .arg(file)
        .output()
        .expect("error running fpcalc");
    let stdout = String::from_utf8_lossy(&output.stdout);
    let mut lines = stdout.lines();
    lines.next();
    let fpstring = lines.next().unwrap();
    let mut fpstring2 = fpstring.split('=');
    fpstring2.next();
    let fpstring3 = fpstring2.next().unwrap().split(',');
    let fpstring4 = fpstring3.clone();
    let yy:u32 = fpstring3.count().try_into().unwrap();

    let mut img = image::RgbImage::new(32, yy);

    let mut y:u32 = 0;
    for line in fpstring4 {
        let b = line.parse::<u32>().unwrap();
        for x in 0..32 {
            let p = (b >> x) & 1;
            let pp = 255 * p;
            img.put_pixel(x, y, image::Rgb([pp.try_into().unwrap(), pp.try_into().unwrap(), pp.try_into().unwrap()]));
        }
        y += 1;
    }
    let outf = file.to_owned() + ".png";
    img.save(outf).unwrap();
}

Cargo.toml:

[package]
name = "aid"
version = "0.1.0"
edition = "2024"

[dependencies]
image = "0.25.6"
