工控组态软件中图形组态子系统的设计与实现

图形组态子系统是工控组态软件的重要组成部分。本文在介绍了采用面向对象技术进行图形组态子系统的设计与实现的基础上，阐述了在设计图形组态子系统过程中图形缩放、旋转、保存等的实现方法。

Graph configuration subsystem is an important part in industrial configuration software。On the basis of introducing the design and implementation of the graph configuration subsystem using the technology of object-oriented，this paper gives the way to implement the procedure of zoom,rotation and save etc.
