#include <itkIdentityTransform.h>

Detailed Description

template<typename TParametersValueType, unsigned int VDimension = 3>
class itk::IdentityTransform< TParametersValueType, VDimension >

Implementation of an Identity Transform.

This class defines the generic interface for an Identity Transform.

It will map every point to itself, every vector to itself and every covariant vector to itself.

This class is intended to be used primarily as a default Transform for initializing those classes supporting a generic Transform.

This class is templated over the Representation type for coordinates (that is the type used for representing the components of points and vectors) and over the dimension of the space. In this case the Input and Output spaces are the same so only one dimension is required.

vector. The rank of the Jacobian will also indicate if the transform
