is used.
You can configure the following CWMachineVision methods to overlay
different types of information about the inspection image:
•
FindStraightEdge
• FindCircularEdge
• FindConcentricEdge
• MeasureMaximumDistance
• MeasureMinimumDistance
• FindPattern
• CountAndMeasureObjects
• FindCoordTransformUsingRect
• FindCoordTransformUsingTwoRects
• FindCoordTransformUsingPattern
You can overlay the following information with all the above methods
except
CWMachineVision.FindPattern:
• The search area input into the method
• The search lines used for edge detection
• The edges detected along the search lines
• The result of the method
Each of the above CWMachineVision methods has a settings object input
that allows you to select the information you want to overlay. Set the
boolean property that corresponds to the information you want to overlay
