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();
}
