The material design specs have added a section on the barcode scanning experience. It would be great if the UX could be recreated by this library.

See https://material.io/collections/machine-learning/barcode-scanning.html

In README.md under Usage, function scan (single mode) I'd recommend either wrapping the alert function in a setTimeout as you did in the demo or removing the alert and using console.log. Currently, the alert will not be displayed. This caused me some head thumping until stepped thru a debug and then remembered the demo used the setTimeout.

This software needs a Help file/Documentation on how to use. This would be considered standard, but I can't seem to locate anything.

I use Zebra TC20 or TC25 Android barcode scanners - they don't finish with a final keypress.

I forked this and hacked in a fix to allow for a time (if more than barcode is larger than x in (x)ms)

Just figured that it may be useful to implement a proper fix for this.

Also I use this libary to handle usb RFID readers - works like a charm.

... test for initCanvas needs to test that it correctly sets Quagga.canvas.dom and Quagga.canvas.ctx, and that those each have an image and an overlay property.

Per #151 once implemented, if you don't have a DOM drawingBuffer then Quagga.canvas.dom.overlay and Quagga.canvas.ctx.overlay should be nullish, there should always be a Quagga.canvas.dom.image and Quagga.canvas.ctx.image when in browse

With reference to the example of reading qr code from image

I tried to pass the sample qr code image path to
`const codeReader = new ZXing.BrowserQRCodeReader()
codeReader.decodeFromImage('./assets/images/sample.png').then((result) => {
console.log(result)
// document.getElementById('resu
