The CogNPointToNPoint type exposes the following members.

Constructors

	Name	Description
	CogNPointToNPoint	Constructs a new instance of this class.
	CogNPointToNPoint(IntPtr)	Constructs a new instance of this class using com pointer.
	CogNPointToNPoint(CogNPointToNPoint)	Constructs a new instance of this class as a deep copy of the given instance.

Methods

	Name	Description
	AddPointPair	Adds a new point to the end of each point set. NumPoints will be increased by one.
	Clone	Returns a deep copy of this class instance. Derived classes that implement Clone should override this method; other clients who wish to clone this instance should call ICloneable.Clone. See also CogSerializer.DeepCopyObject
	ComputeGroupAFromGroupBTransform	Compute and return a best-fit transformation between 'group A' points and 'group B' points. The RMS error of the computation can also be obtained. The returned transform maps points from the 'group B' space to the 'group A' space.
	CreateObjRef	Creates an object that contains all the relevant information required to generate a proxy used to communicate with a remote object. (Inherited from MarshalByRefObject.)
	DeletePointPair	Deletes the point at the given index from each point set. Points with higher indices are shifted to the next lower index, and NumPoints is decreased by one.
	Dispose
	Dispose(Boolean)
	Equals	Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
	Finalize	(Overrides Object Finalize .)
	GetAttributes	Implements the corresponding member of the ICustomTypeDescriptor interface. May be overridden in derived classes to provide custom type information. (Inherited from CogObjectBase.)
	GetClassName	Implements the corresponding member of the ICustomTypeDescriptor interface. May be overridden in derived classes to provide custom type information. (Inherited from CogObjectBase.)
	GetComponentName	Implements the corresponding member of the ICustomTypeDescriptor interface. May be overridden in derived classes to provide custom type information. (Inherited from CogObjectBase.)
	GetConverter	Implements the corresponding member of the ICustomTypeDescriptor interface. May be overridden in derived classes to provide custom type information. (Inherited from CogObjectBase.)
	GetDefaultEvent	Implements the corresponding member of the ICustomTypeDescriptor interface. May be overridden in derived classes to provide custom type information. (Inherited from CogObjectBase.)
	GetDefaultProperty	Implements the corresponding member of the ICustomTypeDescriptor interface. May be overridden in derived classes to provide custom type information. (Inherited from CogObjectBase.)
	GetEditor	Implements the corresponding member of the ICustomTypeDescriptor interface. May be overridden in derived classes to provide custom type information. (Inherited from CogObjectBase.)
	GetEvents	Implements the corresponding member of the ICustomTypeDescriptor interface. May be overridden in derived classes to provide custom type information. (Inherited from CogObjectBase.)
	GetEvents( Attribute )	Implements the corresponding member of the ICustomTypeDescriptor interface. May be overridden in derived classes to provide custom type information. (Inherited from CogObjectBase.)
	GetGroupAPoint	Gets the X and Y coordinates of the 'group A' point with the given index. Valid indices range from 0 to NumPoints-1 inclusive.
	GetGroupAPointX	The X coordinate of the 'group A' point with the given index. Valid indices range from 0 to NumPoints-1 inclusive.
	GetGroupAPointY	The Y coordinate of the 'group A' point with the given index. Valid indices range from 0 to NumPoints-1 inclusive.
	GetGroupBPoint	Gets the X and Y coordinates of the 'group B' point with the given index. Valid indices range from 0 to NumPoints-1 inclusive.
	GetGroupBPointX	The X coordinate of the 'group B' point with the given index. Valid indices range from 0 to NumPoints-1 inclusive.
	GetGroupBPointY	The Y coordinate of the 'group B' point with the given index. Valid indices range from 0 to NumPoints-1 inclusive.
	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)
	GetLifetimeService	Retrieves the current lifetime service object that controls the lifetime policy for this instance. (Inherited from MarshalByRefObject.)
	GetObjectData
	GetProperties	Implements the corresponding member of the ICustomTypeDescriptor interface. May be overridden in derived classes to provide custom type information. (Inherited from CogObjectBase.)
	GetProperties( Attribute )	(Overrides CogObjectBase GetProperties( Attribute ).)
	GetPropertyOwner	Implements the corresponding member of the ICustomTypeDescriptor interface. May be overridden in derived classes to provide custom type information. (Inherited from CogObjectBase.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	InitializeLifetimeService	Obtains a lifetime service object to control the lifetime policy for this instance. (Inherited from MarshalByRefObject.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	MemberwiseClone(Boolean)	Creates a shallow copy of the current MarshalByRefObject object. (Inherited from MarshalByRefObject.)
	ResumeAndRaiseChangedEvent	Re-enables raising of the Changed event after SuspendChangedEvent has been called. Also raises the Changed event if the ChangedEventSuspended count is reduced to zero and any changes were made while events were suspended. Must be called once for each call to SuspendChangedEvent.
	SetGroupAPoint	Sets the X and Y coordinates of the 'group A' point with the given index. Valid indices range from 0 to NumPoints-1 inclusive.
	SetGroupAPointX	The X coordinate of the 'group A' point with the given index. Valid indices range from 0 to NumPoints-1 inclusive.
	SetGroupAPointY	The Y coordinate of the 'group A' point with the given index. Valid indices range from 0 to NumPoints-1 inclusive.
	SetGroupBPoint	Sets the X and Y coordinates of the 'group B' point with the given index. Valid indices range from 0 to NumPoints-1 inclusive.
	SetGroupBPointX	The X coordinate of the 'group B' point with the given index. Valid indices range from 0 to NumPoints-1 inclusive.
	SetGroupBPointY	The Y coordinate of the 'group B' point with the given index. Valid indices range from 0 to NumPoints-1 inclusive.
	SuspendChangedEvent	Temporarily suspends the raising of the Changed event. May be called more than once, and a corresponding call to ResumeAndRaiseChangedEvent must be made for each call to SuspendChangedEvent.
	ToString	Returns a String that represents the current Object. (Inherited from Object.)

Properties

	Name	Description
	ChangedEventSuspended	If nonzero, indicates that the raising of the Changed event has been suspended. This value is incremented when SuspendChangedEvent is called and decremented when ResumeAndRaiseChangedEvent is called.
	ComputationMode	This enumeration specifies how the best-fit transformation between the 'group A' points and the 'group B' points will be computed. Only linear computations are supported in this release.
	DOFsToCompute	This enumeration specifies which degrees of freedom will be allowed when computing the best-fit transformation between the 'group A' points and the 'group B' points.
	HasChanged	If true, the serializable state of this object has changed since the last time it was serialized.
	NumPoints	The number of points in each point set. This is the number of 'group B' points, and also the number of 'group A' points.

Events

	Name	Description
	Changed	Occurs when one or more parts of the object's state may have changed.

Remarks

This interface computes the best-fit (minimum squared error) transformation which maps a set of N "group B" points onto a set of N "group A" points.

Note: This interface exists to enable programmatic users to accomplish low-level fitting between two sets of N points. It is neither a tool nor an operator for a tool.
