CogPMAlignPattern GetTrainedPatternShapeModels Method Cognex VisionPro 9.8
Gets the actual shape models used to train the current pattern. The user provided shape models are clipped using the pixel aligned bounding box of TrainRegion when TrainRegion is not nothing.

Namespace: Cognex.VisionPro.PMAlign
Assembly: Cognex.VisionPro.PMAlign (in Cognex.VisionPro.PMAlign.dll) Version: 75.1.0.0
Syntax
Copy to ClipboardPrint
public ICogShapeModelCollection GetTrainedPatternShapeModels()

Return Value

Type: ICogShapeModelCollection

The collection of shape models.

Exceptions
ExceptionCondition
CogOperatorNotTrainedException

This pattern is not trained.

CogPMAlignWrongTrainModeException

TrainMode is neither ShapeModelsWithTransform or ShapeModelsWithImage.

Remarks

Gets the actual shape models used to train the current pattern. Shape models are clipped using the pixel-aligned bounding box of TrainRegion when TrainRegion is not Nothing.
