centerDistanceTolerance

The maximum allowed distance from centerCoord at which a barcode may still be selected when selectionMethod is CENTER. If multiple barcodes are within the tolerance, the closest one will be selected. The value is expressed in terms of the image size, where 1.0 means the maximum distance which is equal to the diagonal of the image. The default value is 0, which means that barcodes must touch the center of the frame to be selected. Increasing this value can help with selecting barcodes that are close to the center but not touching it.

Default is 0.
