Obr.Active := True; Obr.Configure(syQrCode, saNone, coBinary, 1); // switch-on binary data ... procedure TFormMain.ObrBarcodeDetected(Sender: TObject); begin ... Text := TEncoding.UTF8.GetString(Obr.Barcode[I].Data); // use UTF-8 decoding ... end;
How can I disable recognition of specific barcode symbologies?
To exclude certain symbologies from recognition, add the following line before scanning:Obr.Configure(syQrCode, saNone, coEnableSymbology, 0); // disable QR code symbology
How can I enable recognition of a specific barcode symbology?
To activate recognition for a particular symbology, add the following line before scanning:Obr.Configure(syQrCode, saNone, coEnableSymbology, 1); // enable QR code symbology
