WhiteLinesNumber # get and set (OneDBarcodeReadOptions)
An Int32 that indicates the minimum number of lines of white space above and below the barcode symbol to use when reading a barcode. Must be value greater than or equal to 0. The default value is 3.
A barcode on an image usually has white space around it. This value defines the minimum number of white space lines (in pixels) that must exist around the barcode before it can be read. The default value of 3 means 3 pixels on the top and bottom of the barcode.
Change this value when the barcode is adjacent to another object on the image.
