    'Declaration
     
    Public Property Resolution As Resolution
    'Usage
     
    Dim instance As Device
    Dim value As Resolution
     
    instance.Resolution = value
     
    value = instance.Resolution
    public Resolution Resolution {get; set;}
    public: __property Resolution* get_Resolution();
    public: __property void set_Resolution( 
       Resolution* value
    );
    public:
    property Resolution^ Resolution {
       Resolution^ get();
       void set (    Resolution^ 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 resolutions can be received by the GetSupportedHorizontalResolutions method.
    Example
    This example shows how to acquire images from the device with different X and Y resolutions.
    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();
    }
