Image QR Scanner
The Image QR Scanner node is used to scane an image for a QR code. It's typically used in conjunction with the Open File Picker node, to allow the user to upload a file.
When a QR code has been successfully identified, the node will send a Scan Successful event and the decoded string, otherwise Scan Failed.

|Scan||Triggers a QR code scan in the file provided in the Image File input.|
