    Public Sub ScanColorImageWithImageFilter(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.ImageFilter = ImageFilter.Green
                
        device.Acquire()
    End Sub
