The combination and splitting algorithm and the realization of program in vector graph

ZHAI Wen guo,TONG Li juan (Department of Computer Science and Automation,Beijing Institute of Machinery, Beijing, 100085)  
The combination and separation are two essential operations in etor graphics editing.lt is crucial to ensure all the graphics displayed correctly after the operations of combination and separation. Under the theory of OOP,the way of combining and splitting the graphics and the realization of program are used in the procedure of developing the graph editor. Through the design of all the graphics classes and the combination class CComboDraw, the operation of combination and separation of the graphics is realized successfully. the algorithms of the operation of the combination and separation and the the program to realize the algorithms are put foward. In order to make all the graphics displayed correctly after the operation of the combination and separation, the algorithms of display of the graphics and the program are presented as well.
