) As ICogTransform2D

Public Function GetTransform (

) As ICogTransform2D

public:
ICogTransform2D^ GetTransform(
	String^ toSpaceName, 
	String^ fromSpaceName
)

public:
ICogTransform2D^ GetTransform(
	String^ toSpaceName, 
	String^ fromSpaceName
)

toSpaceName: Type: System String
A valid nonqualified or fully-qualified space name that indicates the coordinate space to which to map points.

fromSpaceName: Type: System String
A valid nonqualified or fully-qualified space name. This name indicates the coordinate space from which to map points into the toSpaceName.

The resulting CogTransform2D.

Exceptions

Exception	Condition
CogSpaceTreeInvalidNameSyntaxException	toSpaceName or fromSpaceName value is not a legal space name.
CogSpaceTreeNotUniqueException	toSpaceName or fromSpaceName is a nonqualified space name and more than one instance of it exists in this tree.
CogSpaceTreeNotInTreeException	The space name does not exist in this tree.

Remarks

Returns a composed CogTransform2D that maps points from one coordinate space to another.
