Hello

We use BarcodeScanner.Scan method to scan Images from PDF-Pages for QR-Codes.
Sometimes if the image is in a bad quality with a lot of grey pixels, the BarcodeScanner.Scan method needs very long to scan the image (1 hour).
Is it possible to set a timeout for the BarcodeScanner.Scan method or to cancel the BarcodeScanner.Scan method?

Best regards
Eduard

Hello,

Thanks for your inquiry.
Normally, our BarcodeScanner.Scan method does not take too long to scan barcodes.
Could you please provide us with the corresponding QR-Codes images, and we will further investigate the cause and see if it can be optimized. You could send your images to us (support@e-iceblue.com) via email. Thanks in advance.

Sincerely,
Elena
