If the NoiseReduction property is none zero then the toolkit will run an image through a noise reduction filter before scanning for barcodes. The filter removes marks from an image that are unlikely to be part of a barcode. A larger value for NoiseReduction will remove larger marks from the image, but may also destroy vital barcode.
Overview PageNo is a 1 based index that specifies the page to be scanned in an image. A value of zero indicates that every page will be scanned Type: SHORT Default value: 0
Overview The Pattern property is a regular expression that each barcode found in an image is compared against. The toolkit will only return barcodes that match the pattern. The toolkit use POSIX extended regular expression syntax. Examples: “ABCDEF” will match all barcodes containing “ABCDEF” (e.g “XYZABCDEFXYZ”) . “ABC[0-9]+” will match all barcodes containing “ABC”
Overview PdfBpp is the number of bits-per-pixel to be used when converting a pdf file into image format, before scanning for a barcode. The value should be 1, 8 or 24. Has no effect when PdfImageOnly is set to True. Type: SHORT Default value: 1
Overview PdfDpi is the number of dots-per-inch to be used when converting a pdf file into image format, before scanning for a barcode. Has no effect when PdfImageOnly is set to True. Type: SHORT Default value: 300
Overview The Photometric property determines how the toolkit interprets a pixel value in a bi-tonal bitmap passed to the ScanBarCodeFromBitmap method. Pixel Value = 0 Pixel Value = 1 Photometric = 0 Black White Photometric = 1 White Black This property is not used with the ScanBarCode or ScanBarCodeFromDIB methods. Type: SHORT Default value: 0
Overview As the SDK scans an image it assigns a score to each barcode candidate. At the end of a scan, any candidates with a score >= PrefOccurrence are reported by the SDK. If no candidate meets this criteria then the SDK selects the candidate with the highest score and reports this barcode if it
Overview When the toolkit checks for a barcode on a scan line in an image, it ignores those parts of the line that are not preceded by the number of white pixels specified by QuietZoneSize. When the property has a value of 0 then the quiet zone is calculated 1/10th of the value of the image
Overview When set to TRUE the toolkit will search for codabar barcodes. Type: BOOL Default value: TRUE
Overview When set to TRUE the toolkit will search for type 128 barcodes. Type: BOOL Default value: TRUE
