MaxLength defines the largest length for a barcode string, including checksum characters. Type: SHORT Default value: 999
When TRUE the toolkit will apply a median filter to the image before checking for barcodes. This is a useful option for high resolution images that contain speckles of black and white. It is not recommended for images where the black bars or white spaces are less than 2 pixels wide. Type: BOOL Default Value: FALSE
MinLength defines the smallest length for a barcode string, including checksum characters. Type: SHORT Default value: 4
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 has a
MinSeparation defines the minimum distance between barcodes of identical value and vertical alignment in 1/300th of an inch. If the distance between two barcodes of same value and on the same alignment is less than MinSeparation then the toolkit assumes that it is a single barcode that has been split into 2 parts by a problem in
MinSpaceBarWidth is the minimum acceptable size for a space between the bars in a barcode. When set to a value of 0 the toolkit will automatically select the best value. Spaces that are smaller than the value used are ignored. Type: SHORT Default value: 0
Normally the toolkit stops at the first positive match for a barcode. When MultipleRead is TRUE the toolkit will check the entire image for barcode strings and record each positive match. Type: BOOL Default value: FALSE
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”
