Description: 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. Platform: |
