矢量图形系统的开发

The Development of Vector Graphics System

矢量图形系统已经成为图形组态平台中一个不可或缺的重要部分，本文基于Vc＋＋平台，应用面向对象的设计方法来设计程序构成，最终完成了包括文档和视图的实现、鼠标的交互绘图、以及图形的选中、平移、旋转、无极放缩等设计目标，同时也实现了自定义格式的矢量图存储。

Vector graphics system has become an indispensable part in graphics configuration platform. In this paper, the program composition is designed by using the method of object-oriented design based on VC＋＋ platform, and finally the design objectives, including the realization of document and view, interactive drawing by mouse, as well as pitching on, parallel shift, rotating and zooming of the graphical objects, have been achieved, meanwhile, the storage for vector graphics with user-defined format is completed as well.
