摘　　要：介绍了ＣＧＩ程序的概念，提出用 ＧＤ绘图软件包为ＣＧＩ程序增加绘图功能的方法。并在ＧＤ绘图软件包的基础上设计了一个Ｗｉｎ３２动态链接库，可方便的链接在ＣＧＩ程序中，实现曲线绘制等功能；给出了一个根据用户输入频率动态显示正弦波信号波形的ＣＧＩ程序样例．GD is a bee graphics library for fast creation of GIP image. It supports most of the commonly requested features for an 8-bit 2D image package, such as lines, circles and fonts. In the base of scarce codes of GD, we design a 32-bit graphics DLL, which can be linked to a CGI program and can supplied graphics functions for it. To show how to add graphics functions by the DLL that is designed on GD, an example program of CGI is supplied in this paper
