Detailed Description

template<class TScalarType = double>
class itk::CenteredRigid2DTransform< TScalarType >

CenteredRigid2DTransform of a vector space (e.g. space coordinates).

This transform applies a rigid transformation in 2D space The transformation is specified as a rotation around an arbitrary center and is followed by a translation.

The need for introducing this transform is that a rotation is not specified simply by an angle, as we use to think, but also by a center of rotation. We use to assume that the center of rotation is the origin of the coordinate system. This assumption, however does not usually hold in applications such as image registration.

In order to initialize this transform a user should provide the following

With these parameters the transform applies first a translation that will move the center of rotation to be the new origin. Next, a rotation is performed around this origin. Then another translation is applied in order to move the origin back to the position of the center of rotation. Finally, the user-specified translation is applied. Note that the user-spedified translation is applied after the image has returned to the original coordinate system. If you want to rotate an image around its center, please specify a null translation and just set the center of rotation. This transform will take care internally of the two translations required to implement a rotation around an arbitrary point.

The serialization of parameters in this transform results in an array of five element ordered as follows

p[0] = angle p[1] = x coordinate of the centre p[2] = y coordinate of the centre p[3] = x component of the translation p[4] = y component of the translation

For convenience, an additional method is available for specifying the rotation in degrees instead of radians.
