    NoiseFilter Property (Device)
    In This Topic
    Gets or sets the noise filter for current scan session.
    Syntax
    'Declaration
     
    Public Property NoiseFilter As NoiseFilter
    'Usage
     
    Dim instance As Device
    Dim value As NoiseFilter
     
    instance.NoiseFilter = value
     
    value = instance.NoiseFilter
    public NoiseFilter NoiseFilter {get; set;}
    public: __property NoiseFilter get_NoiseFilter();
    public: __property void set_NoiseFilter( 
       NoiseFilter value
    );
    public:
    property NoiseFilter NoiseFilter {
       NoiseFilter get();
       void set (    NoiseFilter value);
    }
    Exceptions
    ExceptionDescription
    Thrown if device is in wrong state.
    Thrown if device does not support capability.
    Thrown if the .NET debugger is used and the function evaluation requires all threads to run.
    Remarks
    Call this property only when device is opened (State == DeviceState.Opened).

    Supported pixel types can be received by the GetSupportedNoiseFilters method.
    Example
    This example shows how to apply automatic noise filter to images acquired from the device.
    Public Sub ScanColorImageWithNoiseFilter(ByVal device As Device)
        device.ShowUI = False
        device.DisableAfterAcquire = True
                
        device.Open()
        device.PixelType = PixelType.RGB
        device.UnitOfMeasure = UnitOfMeasure.Inches
        device.Resolution = New Resolution(300.0F, 300.0F)
        device.NoiseFilter = NoiseFilter.Auto
                
        device.Acquire()
    End Sub
    public void ScanColorImageWithNoiseFilter(Device device)
    {
        device.ShowUI = false;
        device.DisableAfterAcquire = true;
                
        device.Open();
        device.PixelType = PixelType.RGB;
        device.UnitOfMeasure = UnitOfMeasure.Inches;
        device.Resolution = new Resolution(300f, 300f);
        device.NoiseFilter = NoiseFilter.Auto;
                
        device.Acquire();
    }
