Members
ValueMemberDescription
0x00000000UseDefault Use the best method for the detected barcode.
0x00000002UseAutoDocumentBinarization Use document image binarization.
0x00000004UseDeblurBinarization Deblure image before binarization.
0x00000008UseFastModeBinarization Use fast deblurring method.
Remarks

Using the default flag detects the best binarization methods for the detected barcode.
