利用C语言代替汇编语言实现高分辨率二值图象的快速显示和移动

THE IMPLEMENTATION OF RAPID DISPLAY AND MOVEMENT OF HIGH RESOLUTION TWO─VALUED IMAGES

本文分析了高分辨率二值图像通过显示器上显示的基本方法。并用Ｃ语言中断函数直接把图像数据送入内存显示及移动。还给出了完整的编和流程图并给出了以ＣＧＡ显示适配器为例的实现高分辨率二值图像的快速显示和移动的用Ｃ语言编写的完整程序。这种方法适用于多值图像及汉字的显示和移动。

In this paper we have analyzed the basic method of displaying high resolution two valued im-ages on the screen,and the method of directly importing image data into memory and moving im-ages on the screen by using the interrupt function of Clanguage. We have also given the completeprogrammed flow chart and the program for rapid display and movement of high resolution twovalued images,which were compiled with the help of C language and illustrated by an example ofimplementation by CGA displaying adapter. This method is also suitable for the display andmovement of multi─valued images and Chinese characters.
