摘要
通过对几种数字插补算法的分析和比较，提出一种更适合于在点阵显示屏中画线的插补算法，利用此方法画出的直线更加理想和平整给出了有关的逻辑关系、公式和软件流程图．
Through analysis and comparison of some digitalinsert methods,a better method more appropriate for LCD is proposed .With it straight lines drawn are more smooth and ideal.Corresponding logic relation and formula,together with softwere flow chart,are presented.
