The filling of polygon is a necessary function in the most graphics transaction software, there are two ways, one is the vector pattern filling and the other is the grid pattern filling. The vector pattern filling was usually used in the one that demands high resolution ratio and high pixel, it couldn't get used widely because of its complicated filling process and wasting times and the grid pattern filling got widely used because of its simple and proficient filling process. The mixed filling between regional vector pattern filling and grid pattern filling inherit the advantages of their two: it could realize the vector pattern's high filling effect with grid pattern's simple filling process. The test experiment of the algorithm indicates that the mixed filling keeps the vector pattern filling's advantage as well as the grid filling's proficient filling process.%区域填充是在现今的大部分图形图像处理软件系统中必不可少的功能,一般有矢量花纹填充以及栅格花纹填充.矢量填充一般应用于有高分辨率,高像素要求的填充,因其填充复杂,时间过程繁琐只有小部分的应用；栅格填充因其填充过程简单,填充方法成熟故得到了广泛使用.矢量栅格混合填充是在综合两种不同模式填充优点的基础上提出的一种全新的填充模式:用简便的栅格填充的过程实现矢量填充所能达到的高品质填充效果.实验结果表明:混合填充保持着矢量填充的缩放不失真的特性,并拥有栅格填充效率.
