CogBlobResult.GetBoundingBox Method

CogBlobResult GetBoundingBox Method

Cognex VisionPro 9.7

Gets a bounding box of the blob that is aligned with the specified axis. The exclude extrema properties of the run parameters are used when calculating the bounding box, except when Axis is set to CogBlobAxisConstants::PixelAlignedNoExclude.

Namespace: Cognex.VisionPro.Blob

public CogRectangleAffine GetBoundingBox(

Public Function GetBoundingBox ( 
	axis As CogBlobAxisConstants
) As CogRectangleAffine

Public Function GetBoundingBox ( 
	axis As CogBlobAxisConstants
) As CogRectangleAffine

public:
CogRectangleAffine^ GetBoundingBox(
	CogBlobAxisConstants axis
)

public:
CogRectangleAffine^ GetBoundingBox(
	CogBlobAxisConstants axis
)

Parameters

axis: Type: Cognex.VisionPro.Blob CogBlobAxisConstants

Return Value

Type: CogRectangleAffine
The returned bounding box: a CogRectangleAffine.

Exceptions

Exception	Condition
ArgumentException	axis is not a member of CogBlobAxisConstants.
CogBlobEntireBlobExcludedException	The entire blob has been excluded because you specified an extrema exclusion setting greater than or equal to the area of the blob.
InvalidOperationException	If no result data is available.

Remarks

Gets a bounding box of the blob that is aligned with the specified axis. The run-time ExtremaExcludeMode settings are used when calculating the bounding box, except when axis is set to PixelAlignedNoExclude.

The returned bounding box is in the selected space of the InputImage.

Note: If you specify PixelAlignedNoExclude for axis, the tool ignores the extrema exclusion settings and returns a graphic that is in the pixel space of the input image. This option requires less time than the other options to execute.
