FPW图形过程库

分析了ＦｏｘＰｒｏｆｏｒＷｉｎｄｏｗｓ在图形程序设计支撑上的弱点，如仅能绘极简单图形、提供的ＧＥＮＧＲＡＰＨ工具只能画预先定好的几种统计图。为解决这些问题，提出了一个以画点过程为基础，采用高效的扫描转换算法实现的包括画点、画线、画圆等功能齐全的ＦＰＷ通用过程库方案，可支持３２０×３２０象素、１６色。

The paper analyzes the deficiency of Fox Pro for Windows in graphic program design support,such as,it can only be used to plot a simple graphic and GENGRAPH tools provided only to plot several preset statistic graphs.In order to solve these problems,the plan of FPW general purpose process program including a full functions of plotting dots,lines and circles,is introduced which is realized through an efficient scanning switch algorithm and on the bases of ploting dot procedure,and can support 320×320 pixel,16 colors,and an extendable 256 colors.
