## Code highlights

1. Setup the gauge widget.
   ```python
   self.gauge_widget = EasyGaugeWidget()
   self.gauge_widget.set_gauge_type(eVision.EShapeType.PointGauge)
   self.gauge_widget.set_transition_type(eVision.ETransitionType.Bw)
   self.gauge_widget.set_transition_choice(eVision.ETransitionChoice.LargestAmplitude)
   self.gauge_widget.set_view_results(True)
   ```
2. Perform a measurement with the gauge.
   ```c++
   self.xxx_gauge.Measure(self.image)
   ```
