一个直接用填线填充任意区域的算法

A FILLING ALGORITHMIC OF FILLING ANY REGION WITH ITALICIZED FILLINGLINE

用填充线填充任意区域方法之一是将图形连同填充线绕原点作旋转变换再用水平填充线算法来实现．但这种方法要作两次旋转变换，计算量大．方法之二是郭启全等介绍的方法但没有解决扫描线正好通过区域边界的某些边时的情况．

One of the methods of filling region with italicized fillingline is that region and italicized fillngline rotate around origin of coordinate then fill region with level fillingline algorithmic.But this method need to do two time transformation of rotation,quantity of calculation is much enormous.Another method has been introduced .But it havn't solved the probblem that fillingline ove rlap with bound of region.this paper can solve these problems mentioned above.
