一款开源的完整矢量绘图控件源码,支持直线、弧线、矩形、圆角矩形、椭圆、多边形、星形、文本和图片等的绘制，支持旋转、缩放、选择、排列等操作，总的说来功能还是不错的！其实如果稍微懂点计算机图形学的知识要做出比这个还要完善的矢量绘图软件应该是没有问题的。 VB6本身对于绘图的支持是非常弱的，因此一般直接通过其内置方法实现的绘图效率都成很大的问题。解决方法之一是采用Windows API来进行底层GDI的绘制，更好的方法是采用GDI+来绘图，这样效果会更好。 -A complete open source vector graphics controls in support of a straight line, arc, rectangle, rounded rectangle, ellipse, polygon, star, text and pictures, such as rendering, support for rotation, zooming, selection, arrangement and other operations, the total to function or that good! In fact, if a little point of computer graphics to understand the knowledge to make than that perfect vector drawing software should not be any problem. VB6 their support for the graphics are very weak, so the general method of directly through its built-in graphics to achieve efficiency into a big problem. One solution is the use of Windows API for the underlying GDI rendering, and better way is to adopt GDI+ To graphics, so the effect will be even better.

WGF (windows 图形基金会) 为windows下的gdi和gdiplus双缓冲绘图框架。框架在VC6.0下使用C + + 语言开发而成并以可扩展的MFC动态链接库形式提供，适用于windows操作系统。WGF为完全开源的免费产品，可以用于任何商业的和非商业的用途。WGF设计的目的是对windows下的gdi和gdiplus双缓冲绘图进行封装和优化。WGF封装了使用gdi和gdiplus进行双缓冲绘图的实现细节，使用框架进行双缓冲绘图时感觉就像是在窗口上绘图一样。同时，WGF通过将绘图内容划分为静态场景和动态场景以及通过采用gdi和gdiplus混合绘图的方式对windows下的gdi和gdiplus绘图进行了优化。

在vc++ 环境下对mapinfo的mif mid数据格式的文件进行操作 （本程序附带部分数据方便大家学习） 本程序不仅对道路、 等高线、 电力层、 独立地物、居民地、水系、图廓线等图层进行显示，而且实现了 缩放 漫游 开窗放大等基本的功能.是研究mapinfo数据格式的一个很好参考源码。-vc environment in the mid mif MapInfo data format for the paper operations (the procedure incidental part of the data to facilitate learning) of the procedure not only for roads, contour lines, power layer, independent features, residential areas, river systems, such as the map layer profile for, and the realization of roaming window zoom to enlarge the basic functions. MapInfo data research is a good format for Senate Source examination.
