How to implement Zoom in/out functionality in QR Scanner for Fiori apps on iOS devices?

[Rakesh_Kr]

Hello All,

We have used standard library "sap.ndc.BarcodeScanner" for implementing Bar-code/QR code scanner and it works fine. We now have a requirement to provide zoom in/out functionality when user opens camera/device for scanning, however we can't find this feature in standard library for iOS. We also tried to look into custom/3rd party libraries like zxing/quagga.js, but we can't find any solution there as well for implementing custom zoom feature for scanning.

If anyone has Implemented this feature, it would be really helpful if you can provide some insights or documents/help link of how to.

oliver.graeff gregorw saurabh.vakil Any suggestions, do you know when this feature will be available as part for standard library?

Thanks,

Rakesh

You can use ui5-tooling-modules and html5-qrcode to implement a QR Code Scanner yourself.

They implement a zoom feature recently:
https://github.com/mebjas/html5-qrcode/releases/tag/v2.3.2

I guess for the other javascript QR Code Reader Libraries you have to write it yourself.
