This design not only implements the function very well needed by generic graphic system, but also has good hie￣rarchy, understandability, encapsulation and extensibility in terms of modern software engineering thinking. Firstly, the whole design frame is introduced, and then several key classes are presented by UML class diagram, at last the interaction is presented by UML interaction diagram.
