Detailed Description

The SbBox2s class is a 2 dimensional box with short integer coordinates.

This box class is used by other classes in Coin for data exchange. It provides storage for two box corners with short integer coordinates, which is among other things useful for representing screen or canvas areas in absolute window coordinates.
