利用离散余弦变换来对图像进行压缩的vc++程序源代码

Hough变换用来在图象中查找直线。它的原理是：假设有一条与原点距离为s，方向角为θ的一条直线，直线上的每一点都满足方程 s=x*Cosθ+y*Sinθ，利用这个事实，我们可以找出某条直线来。这段程序，用来找出图象中最长的直线。-Hough Transformation is used for searching lines in an image . Here is the principle: Assume there is a line whoes direction is "sita" , and the distance from the origin to this line is s. So each point in this line satisfies the equation : s=x*Cos(sita)+ y*Sin(sita) . We can find out the lines based on this fact. And this programme is to find out the longest line in the image.

用VB在图片框中绘图时有一个缺点是无法选取所绘制的直线，本程序可为你解决这一难题。-VB box graphics in the pictures have a deficiency is not selected by the drawing of a straight line. this procedure can you resolve this problem.

这是一个可以在VC中直接显示gif动画的一个类，他只需要将gif动画当作一个图像资源加入到VC中，然后再在那个控件的属性里面进行一些设置就可以了-This is a VC in a direct indication of an animated gif category, he simply have animated gif image as a resources into VC, and then at that controls the properties inside some settings to the

画板是一个可以自已定制画板界面和图库并按分类进行作画的一个小程序,界面非常精美。其中PaintDlg.DLL封装了画板的主模块。Paint.Exe为执行调用画板的一个可执行文件示例(用于指定打开画板是在什么类型下，如卡通画或工程画分类等等)。本软件的VC++源代码全部开源，你可以能照Paint.exe对应VC++工程是如何调用此画板动态联接库的WIN32API，以便你可以在其它开发语言中直接调用打开画板即可。-Paint Vc++ source Code
