摘要
对工业生产过程控制和管理中的计算机图形显示,提出一种压缩存贮和滚动的新方法。新方法的实施,可使图形数据占用的存贮空间减少约80%,一般地不需使用外存,从而大大提高了显示速度,解决了普通微型机存贮空间和显示速度之间的矛盾,有效地提高了普通微机的功能/价格比。所提出的方法均经工程实践检验过,效果良好。
In process control and management of industrial productiort, the exterrtal memory is often neccssary for the figure display of microcomputer. This paper presertts a new method of compressing memory and rolling of figure. Using this method, the memory space of figure data can be decreased about 80% and in general, no external memory is needed. Thus, the speed of display is greatly increased and the contradiction between memory space and speed of display will be resolved. The practical engineering applications show that the result is quite good.
