CogGeneralContour.RemoveSegments Method

CogGeneralContour RemoveSegments Method

Cognex VisionPro 9.5

Removes all segments from StartSegment up to, but not including EndSegment, possibly disconnecting at StartSegment's start point, and/or EndSegment's start point. If EndSegment is Nothing, segments are removed from StartSegment to the end.

Parameters

startSegment: Type: Cognex.VisionPro CogGeneralContourSegmentIterator
The first segment to remove.

endSegment: Type: Cognex.VisionPro CogGeneralContourSegmentIterator
The ending segment. This segment is not removed. If this value is Nothing, all segments from startSegment to the end are removed.

Events

CogGeneralContour Changed	Fires when the segments are removed. The following state flags may be affected:

Event Type

Reason

CogGeneralContour Changed

Fires when the segments are removed.

The following state flags may be affected:

Exceptions

Exception	Condition
ArgumentException	startSegment is Nothing.
CogIteratorInvalidIteratorException	startSegment is invalid.
CogShapeBadContourSegmentSetException	startSegment is positioned after endSegment.

Remarks

Removes all segments from startSegment up to, but not including endSegment. RemoveSegments(CogGeneralContourSegmentIterator, CogGeneralContourSegmentIterator) may disconnect the contour at startSegment's or endSegment's start point. If endSegment is Nothing, all of the segments from startSegment to the end of the contour shape are removed.

Note: Any CogGeneralContourSegmentIterator positioned at startSegment through the segment before endSegment become invalid. Other iterators are unchanged.
