应用程序屏幕图像随机截获及其快速显示技术

A RANDOM APPROACH TO GETTING SCREEN PICTURE IN APPLICATION PROGRAM

本文提出了一种利用Ｗｉｎｄｏｗｓ剪接板随机截取ＤＯＳ或Ｗｉｎｄｏｗｓ应用程序屏幕图像的方法，并通过Ｐａｉｎｔｂｒｕｓｈ工具对图形进行修改、编辑、合成，然后以ＢＭＰ格式位图文件保存。此后在分析ＢＭＰ位图格式及ＳＶＧＡ卡显示原理的基础上，提出了一种位图在ＳＶＧＡ卡上以高分辨率２５６色快速显示的技术。

In this peper,a new method is posed for Intercepting the screen pictures of DOS of Windows Application Program. These picrures can be compiled modified compounded in Paintbrush,and saved as BMP file. Finally by analysing the pattern of BMP bitmap file and the display prindple of Super VGA, a new technology is posed for displaying rapidly thane pictures with high resolution and 256 colors in Super VGA.
