We created a shipping barcode. Barcode was saved to a file. (attachment 549label.JPG). Barcodescanner correctly reads tracking number. I printed out the barcode and took a picture with a webcam, and cropped the pic using jquery.webcam, and sdaved to a file.
The second attached file, is the saved webcam pic of the shipping label. When I execute Spire.Barcode.BarcodeScanner.Scan(sPath2 & "WebcamPicOfLabel.jpg", False), the result is the number 6.
Dim data4 As String() = Spire.Barcode.BarcodeScanner.Scan(sPath2 & "549label.JPG", False)
