可以抓取当前屏幕，完成按下键盘的“PringScreenSysRq“键的功能。不同的是，这个程序还可以在抓取框中滚动抓取来的屏幕，可将其直接保存为BMP位图文件。-You can grab the current screen, press the keyboard to complete the "PringScreenSysRq" button function. The difference is that this program can also grab the box to scroll the screen grab can be directly saved as a BMP bitmap file.

这是数字图像编程与实现系列源码之一。请继续关注与之配套的系统源码的上传，下载完后细细欣赏其中的代码，一定会有所收获的，对机器视觉与图像编程的理解会加深大一步。-This is the Digital Image Series programming and achieve one source. Please continue supporting concern with the system source code upload, download, after careful to appreciate the code, there will be harvested, the machine vision and image understanding of the programming will deepen big step.

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.
