摘要
介绍现行基于矢量图形反走样技术的几种实现方法 ,给出了一个较为适用的快速反走样算法 ,介绍了它的原理、算法并将它的结果在不同环境下与走样直线作了对比 ,最后利用它对数字地图和矢量字符进行了反走样分析。
The paper gives a general reference to antialiasing technology and some sorts of antialiasing methods based on vectorial graphics. At the same time, the authors lay an emphasis on a fast antialiasing method, introduce its theory and compare its results with aliasing line under different environments. At last, some experiments on digital maps & vectorial chars are given.
