AutoCAD中多边形调影像功能的实现

Realization of use Polygon Inserted Images in AutoCAD

目前,AutoCAD以其强大的数据编辑和管理功能已被广大用户用作基础的数据操作平台,而矢量数据与影像数据的叠加将会使数据源更加直观、生动。但在AutoCAD平台下经常遇到需按多边形范围算图幅号,调地形图、调影像图的情况,AutoCAD中并无此类功能,本文就此问题阐述解决的思路和方法。

At present,AutoCAD with its powerful editing and management functions has been widely used as the basis of the data user operating platform,while the vector data and orthophoto data will be superimposed on the data source is more intuitive and vivid.However,often encountered in the AutoCAD platform basis having polygon rendering rate number range,tone topographic maps,image maps transfer case,AutoCAD there is no such function,the article set out to solve this issue ideas and methods,and carries on the re-development using VBA,has realized this function.
