一种改进的多边形填充算法

An Improved algoriehm of Polygon Filling

提出了一种基于边界标志的多边形填充算法，无须求交，无须乘除法运算，具有较高的运行效率，且填充精确．如果硬化后，其效率将会更高．

An algoriehm of polygon filling based on beundaries mark is described, in which finding crossing, multiplicator and division is unnesessary. The running efficiency is high, and the filling is more precise. The efficiency will be raised if hardening.
