    Public Property PixelType As PixelType
    'Usage
     
    Dim instance As Device
    Dim value As PixelType
     
    instance.PixelType = value
     
    value = instance.PixelType
    public PixelType PixelType {get; set;}
    public: __property PixelType get_PixelType();
    public: __property void set_PixelType( 
       PixelType value
    );
    public:
    property PixelType PixelType {
       PixelType get();
       void set (    PixelType 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 GetSupportedPixelTypes method.
    Example
    This example shows how to acquire part of color image with 200 dpi from the device.
    Public Sub ScanColorImage(ByVal device As Device)
        device.ShowUI = False
        device.ShowIndicators = False
        device.DisableAfterAcquire = True
                
        device.Open()
        device.PixelType = PixelType.RGB
        device.UnitOfMeasure = UnitOfMeasure.Inches
        device.Resolution = New Resolution(200.0F, 200.0F)
        device.ImageLayout.[Set](1.0F, 1.0F, 5.0F, 5.0F)
                
        device.Acquire()
    End Sub
    public void ScanColorImage(Device device)
    {
        device.ShowUI = false;
        device.ShowIndicators = false;
        device.DisableAfterAcquire = true;
                
        device.Open();
        device.PixelType = PixelType.RGB;
        device.UnitOfMeasure = UnitOfMeasure.Inches;
        device.Resolution = new Resolution(200f, 200f);
        device.ImageLayout.Set(1f, 1f, 5f, 5f);
                
        device.Acquire();
    }
