Version 2.3.2

Features or bug fixes.

• Hide margin of parent container when camera selection UI is hidden (if only 1 camera is found.) - Issue#599, PR#607 by adamwolf@.

Support for zoom slider in Html5QrcodeScanner. Added basic support for zoom feature under configuration flag (not enabled by default). This was raised in issue issue#330.This should help address some focus issues raised so far.

Not supported on Safari or any IOS browser though!

How to use

let html5QrcodeScanner = new Html5QrcodeScanner(
    "reader", 
    { 
        fps: 10,
        qrbox: qrboxFunction,
        useBarCodeDetectorIfSupported: true,
        rememberLastUsedCamera: true,
        aspectRatio: 4/3,
        showTorchButtonIfSupported: true,
        showZoomSliderIfSupported: true,
        defaultZoomValueIfSupported: 2
        // ^ this means by default camera will load at 2x zoom.
    });
