Granularity # get and set (PatchCodeBarcodeReadOptions)
An Int32 that indicate the number of scanned lines per column to skip when reading a barcode. Must be a value greater to or equal to 1. The default value is 9.
A value of 9 means that each tenth line will be scanned when looking for a barcode. Scanning every line will slow the search process while skipping too many lines may skip over the barcode.
