GIS软件中矢量编辑Undo/Redo功能的设计和实现

Design & Development of Undo/Redo for Vector Editing in GIS Software

针对GIS软件中矢量编辑Undo/Redo操作问题,提出了一种解决方案.本文在对Undo/Redo原理进行研究与分析的基础上,设计出其数据结构以及功能函数,并给出了主要实现代码.实践应用表明,该方案能够满足矢量编辑对撤销与恢复功能的需求.

This paper presents a method to solve the problem of the Undo / Redo operations in GIS software.The Undo/Redo principles were researched and analyzed,then its data structure and implementation functions were designed,and the main code was given.Practical application shows that the method can meet the vector editors Undo/Redo requirement.
