QuietZoneSize - size of quiet zone around barcode
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 resolution (e.g. 10 pixels in a 100 dpi image).
Default value: 0
