Detailed Description

Public interface for all image transition classes.

This contains 2 methods:

• GetDescription simply returns a GUI usable identifier for the implementing class
• GetFrame receives 2 RGB24 images, the width, height and a positional indicator. It then carries out some operations on the two and returns the output in the first.
