目前支持autocad中DWG文件读写的源码除了用python写的phythonCAD，恐怕就只剩这个了。可是为什么该站要限定java和C才开通呢，其实有一些其他语言的源码也很经典啊-Currently supports autocad in the source code to read and write DWG files besides using python write phythonCAD, I am afraid the only place this has been. But why the station should be limited to java and C only to open it, in fact, have a number of other languages source code is also very classic ah

加密mapinfo图形的源程序，很全的哦-Mapinfo encryption graphics, is full of Oh

不用注册就可以完成各种常用的地图投影：UTM、Albers、高斯、兰勃特、墨卡托等几十种投影，以及它们之间的相互转换；数据处理方式多样：单点、多点、文件方式；椭球可选；注册后功能更多。 -Registration can be completed without a variety of commonly used map projection: UTM, Albers, Gauss, Lambert, Mercator, etc. dozens of projection, and their mutual conversion data processing and diverse ways: a single point, multi-point , paper ellipsoid optional register more after the function.

本算法是我根据网上的一篇论文提供的一种思路，自己编写代码实现的缓冲区算法，编写本算法的初衷只是为了服务自己的项目，现在发布出来也是为了方便大家，以使大家免得再周折一番，但请务必不要作为学术论文发表。 1.MathTool.cs /******************************************************* * 文档作者：dxj * 创建时
