摘要： IGS-2D是以IBM-PC系列机基本系统为基础实现的一个交互式二维制图系统。借助于该系统,操作者不用编程,只需通过对键盘上一组预先定义的功能键和四个光标控制键的操纵,方便地选择以菜单形式给定的各种命令,绘制以点、线、圆等基本图形元素构成的屏幕图象。此系统还包括了删除、变换、存取和硬拷贝等较完备的图形编辑功能。

Abstract: IGS-2 D is an interactive two-dimensional graphics system which is implemented on the base of the basic system of IBM-PC series microcomputer. With this system, the operator can easily select various commands given in menu form and create a screen image which consists of basic graphic elements such as points, lines and circles, by using a set of predefined function keys and four cursor keys in the keyboard. This system also involves relatively complete editing functions of cancel, transformation, access and hard-copy. Programming is unnecessary.
