| 摘 要： | 以嵌入式设备上Mobile SVG表示模型为基础.分析了反走样技术在低端设备上实现的具体问题.利用后滤波的原理.对多邻接点时新边界点的选择和轮廓端点的对称合成等同题进行了分析.采用构造拟合曲线查找表进行曲线拟合的方法实现反走样.由于映射关系独立于具体图形绘制而事先已经建立.因而计算量不大,对于低端设备图形应用非常适合.实验证明该方法用于Mobile SVG在嵌入式设备上显示时反走样有很好的效果.

| Abstract: | This paper first analyzes the antialiasing method on low end devices based on Mobile SVG representation model.By use of the theory of after filter,the problems of selecting new boundary point when several points border upon each other and symmetrical combination for outline points are analyzed.Finally,the antialising is implemented by simulating curves with lookup table.Because the mapping relationship that is independent of material graph and has been established in advance,the workload of calculation is n... |
