dwg源码C语言,对开发读取Auto Cad程序很有用途。-dwg resources for c,it is use for development of Auto Cad

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.

JEPG图像中数字的识别，能实现JEPG图像中0~9之间数字的识别功能-JEPG of digital image recognition, to achieve JEPG image number between 0 ~ 9 recognition

需求： 1. 系统能够根据例子图像在图像数据库中检索出相似的图像； 2. 对检索结果进行排序（根据与例子图像的相似性进行排序）并显示在用户 界面上； 3. 系统能够计算检索结果的平均查准率（Average Precision）。 平均查准率计算方法： 平均查准率是在一个查询的所有相关对象被返回后的平均准确率： 其中r是排列顺序，N为返回结果的个数，NR是数据集中所有相关结果的个 数，函数R⋅ ()为一个二值函数（当第r 个返回结果为与例子图像相似时为1，否 则为0），P⋅ ()为前r个返回结果的查准率（前r个结果中相似图像的数量除以r）。
