基于GDI+的缓冲区建立及边界描述方法

A Way to Establish Buffer Area and Describe Boundary Based on GDI+

GDI+是早期Windows版本中包括的图形设备接口GDI的新版本,为应用编程接口,通过一组C++类提供接口功能,负责系统与绘图程序之间的信息交换,处理所有Windows程序的图形输出。基于GDI+实现各种缓冲区的建立和边界描述,能够快速、有效地完成各种复杂线状、面状地物的缓冲区建立工作,从而更好地为交通建设、公共设施工程规划、物探作业等提供服务。实验表明,此方法也能够有效地对复杂线状、面状地物的缓冲区的边界及其拓扑结果进行描述。

GDI＋ is a new edition of GDI included in an early edition of Windows.This API provides interface function through a group of C＋＋ type.It is responsible for the information exchange between the system and plot program and manages the graphic output of all Windows program.It can establish the buffer areas for all kinds of complex linear and area planimetries fast and effectively to serve communication construction,public facilities project programming and mineral detection,etc.Experiment showed that this way was also able to describe the buffer boundary of complex linear,area planimetries and its topological results.
