可扩展矢量图形编辑组件设计及其实现

 矢量图形应用非常广泛，但是缺少可动态扩展图元库的矢量图形编辑组件，如何设计可重用矢量图形组件已成为提高设计效率、改进设计质量的重要课题之一．通过对图形编辑组件需求的分析，利用Java平台和反射机制构建矢量图形的方法，包括复合图元创建，图元的显示和保存，图元的缩放和拖拽，漫游和鹰眼等关键技术，规范了设计思想和设计架构．设计出矢量图形编辑组件，可以通过已有图元的组合和派生，达到可扩展、可编辑的效果．

The Design and implementation of expansible vector graphics editor component

Vector graphics are widely used,but lack of dynamically extensible library with the primitive components of vector graphics editor.It has become an important problem that how to design reusable components to enhance the design efficiency and improve the design quality.After analyzing the needs of graphic editing components,we made the most of the Java platform and the reflection mechanism to build the vector graphics system,which included the vital technologies of composite graphics’ creating,displaying,saving,zooming,dragging,roaming,Hawkeye,etc,and specify the principles of the design ideas and architecture.The designed vector graphics editor components can be expanded and edited with the existed and derived primitive graphics components.
