Crate dqr

Expand description

QR Scanner in Rust. Ported from quirc.

§Example

//// open the image from disk
//let img = image::open("tests/data/Hello+World.png").expect("failed to open image");

//// convert to gray scale
//let img_gray = img.into_luma8();

//// create a decoder
//let mut decoder = quircs::Quirc::default();

//// identify all qr codes
//let codes = decoder.identify(img_gray.width() as usize, img_gray.height() as usize, &img_gray);

//for code in codes {
//    let code = code.expect("failed to extract qr code");
//    let decoded = code.decode().expect("failed to decode qr code");
//    println!("qrcode: {}", std::str::from_utf8(&decoded.payload).unwrap());
//}
