Inheritance diagram for GUIPerspectiveChanger:

Detailed Description

This is the interface for implementation of own classes that handle the interaction between the user and a display field. While most of our (IVF) interfaces allow zooming by choosing the rectangle to show, other types of interaction are possible and have been implemented. To differ between the behaviours, all types of interaction between the user and the canvas are send to this class: mouse moving, mouse button pressing and releasing.
