Crate qrcode [−] [src]

QRCode encoder

This crate provides a QR code and Micro QR code encoder for binary data.

extern crate qrcode;
extern crate image;

use qrcode::QrCode;
use image::GrayImage;

fn main() {
    // Encode some data into bits.
    let code = QrCode::new(b"01234567").unwrap();

    // Render the bits into an image.
    let image: GrayImage = code.render().to_image();

    // Save the image.
    image.save("/tmp/qrcode.png").unwrap();
}
