BarcodeOrientationEnum enumeration constants are used to denote the types of barcode orientation that can be detected by ABBYY FineReader Engine. It is used by the BarcodeParams object. 
typedef enum {
 BO_Unknown       = 0x00000000,
 BO_Left_To_Right = 0x00000001,
 BO_Down_To_Top   = 0x00000002,
 BO_Right_To_Left = 0x00000004,
 BO_Top_To_Down   = 0x00000008,
 BO_Autodetect    = BO_Left_To_Right | BO_Down_To_Top | BO_Right_To_Left | BO_Top_To_Down
} BarcodeOrientationEnum;
