symbology
Barcode symbology.
A Type of the derived class associated with a specified symbology or the BarcodeData type when the symbology does not have a specialized data class.
Currently, this method returns the following values:
Symbology | Return type |
---|---|
BarcodeSymbology.Aztec | Type of AztecBarcodeData |
BarcodeSymbology.Datamatrix | Type of DatamatrixBarcodeData |
BarcodeSymbology.Maxi | Type of MaxiBarcodeData |
BarcodeSymbology.MicroPDF417 | Type of MicroPDF417BarcodeData |
BarcodeSymbology.MicroQR | Type of MicroQRBarcodeData |
BarcodeSymbology.PDF417 | Type of PDF417BarcodeData |
BarcodeSymbology.QR | Type of QRBarcodeData |
All other BarcodeSymbology members | Type of BarcodeData |
