CogCNLSearchPattern.PartialMatchLimitLeft Property

CogCNLSearchPattern PartialMatchLimitLeft Property

Cognex VisionPro

Limit-left specifies how many columns of pixels on the left side of the pattern may lie outside of the search region and still be found. Partial match results are not supported by the CNLPAS algorithms.

Remarks

Limit-left specifies how many columns of pixels on the left side of the pattern may lie outside of the search image and still be found. Partial match searching is only supported for the Linear Search algorithm.

The partial match limits that you specify for training are only used during training if you have specified advanced training. Advanced training uses these limits to help train a pattern that will be effective at run time when the pattern is partially outside of the image.

The training-time partial match limits that you specify are used at run time if you specify true for the PartialMatchLimitsUsePattern property.

Default Value: 0
