Detailed Description

transformation base class

A transformation is defined by its matrix and the corresponding inverse. The transformation routine of the image class will use both to construct the result.

The extent of the newly created images can be defined in several ways: (1) size of the original image (2) maximal size to fit the transform

Usage of this class allows an arbitrary transformation, in form of a 4x4 matrix, to be specified. If only the forward matrix is given, the inverse will be calculated automatically.
