contourAtIndexError

public VNContour contourAtIndexError(long contourIndex,
                                     org.moe.natj.general.ptr.Ptr<NSError> error)

Returns the VNContour object at the specified index, irrespective of hierarchy.

Parameters:

contourIndex - The index of the contour to request. Valid values are in the range [0..contourCount-1].

error - The error returned if the index path is out of range.

Returns:

The detected VNContour at the specified index without regard to hierarchy.

contourAtIndexPathError

                                         org.moe.natj.general.ptr.Ptr<NSError> error)

Returns the VNContour object at the specified index path.

Use the indexPath property from a VNContour instance to pass to this method.

Parameters:

indexPath - The index path is the heirarchical path to the contour.

error - The error returned if the index path is out of range.

Returns:

The VNContour object at the specified index path.
