    Syntax
    'Declaration
     
    Public Property imageScaleFactor As Single
    'Usage
     
    Dim instance As BarcodeReadRequestParams
    Dim value As Single

    public float imageScaleFactor {get; set;}

       float value
    );
    public:

       float get();
       void set (    float value);
    }

    Property Value

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

    Target Platforms: Windows 8, Windows 7, Windows Vista, Windows XP, Windows Server 2012, Windows Server 2008, Windows Server 2003
