Detailed Description

ImageBox.

This class handles the bounding box of an image. It allows to store a reference point inside it and allows to handle some operations and conversion on pixels coordinates.

Shall be initialized with the dimensions of the image, in order to be able to convert back and forth from Points to Offsets.
