By default, the barcode engine will search for all 1D barcodes. The 1D barcode set includes all types, except PatchCode, PostNet, PDF417, Data Matrix, IntelligentMail, Royal Post Mail 4-State, QRcode, Aztec, and Australian Post 4-State.
The barcode recognition engine is capable of detecting 1D barcodes in an image without any prior knowledge of the barcode type. However, you can speed up the recognition process by specifying a barcode type. Barcode types can be combined. For example, if you want to specify UPC-A and CODE 93, you should call SetBarcodeReaderType method 2 times with BarcodeType parameter BC_StyleUPCA and BC_StyleCode93.
Passing BC_StyleUnknown value to the method clears list of barcode types to search for during recognition and barcode engine will use default value - all 1D barcodes. Passing other BC_BarcodeStyle enumeration value will add this barcode type to the list of searched barcodes and barcode engine will search only for these barcode types.
