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);
