CAI软件图形处理技术

计算机辅助数学软件往往要在同屏下管理文本和图形文件直接采用ＤＯＳ环境下常用的绘图方法制图，在图形的自下而上或管理等方面不尽人意。本文在研究ＣＡＩ软件中图形特点的基础上，提出了一种借助Ｃ语言，将ＡＵＴＯＣＡＤ平台下制作的局部图形转换成可执行文件的图形处理技术，有效的解决了ＣＡＩ开发系统制作，调用图形文件并同时管理文本，图形模式的问题。

THE RESEARCH ON GRAPHIC PROCESSING TECHNIQUE OF CAI SOFTWARE

CAI (Computer Aided Instruction) software systems often need to manage text and graphic files in the same screen. It is difficult to obtain satisfactory results on producing and managing graphs by adopting directly the common drawing method under DOS environment. This paper, on the basis of researching graph features in CAI software, puts forward a graphic processing method of converting a local graph mode at AUTOCAD bench into a executable file by C language. This method effectively solves the problems of making and transferring graphic files and managing text and graphic mode at the same time in the CAI development systems.
