add toStream() to get a stream from canvas back #23

Closed sir-bobselot closed 3 years ago

sir-bobselot commented 3 years ago

Added a toStream() function to be able to work with the canvas stream like this:

const qrCode = new QRCode(options);

const out = fs.createWriteStream(`${__dirname}/streamt.png`);
const stream = await qrCode.toStream();
stream.pipe(out);
out.on('finish', () => console.log('Finsihed'));
