    Property Value

    Minimum value is 0.1, maximum value is 4.0. Default value is 1.

    Recomendations: To increase recognition quality - upscale image if image contains very small barcodes (single bar or matrix cell is less than 1.5 pixel). To increase recognition speed - downscale image if image contains large barcodes (single bar or cell is greater than 6 pixels). Optimal single bar or matrix cell size is 3..6 pixels.
