# AAA - AnimeAntiAliasing
#
# Thanks @ Didée, mf, Akirasuto, SpikeSpiegel & ScharfisBrain...
#________________________________________________________________________________________
#
# Usage: AAA(Xres, Yres, Xshrp, Yshrp, Us, Ds, chroma)
#________________________________________________________________________________________
#
# Xres/Yres = The final resolution... InputSize = OutputSize is the default
#
# Xshrp/Yshrp = Unfilter strength... Settings of 15,15 are the defaults
#
# Us = Resizer for upsampling... 0 = PointResize (default) / 1 = Lanczos
#
# Ds = Resizer for downsampling... 0 = Bilinear (default) / 1 = Bicubic / 2 = Lanczos
#
# Chroma = Enable/disable chroma antialiasing... Disable = false (default) / enable = true
#________________________________________________________________________________________
#
# Example...
#
# Import("C:\Programme\AviSynth 2.5\plugins\AAA.avs")
#
# AAA(720,576,20,20,1,2,chroma=false)
#________________________________________________________________________________________

拜倒感谢
用了函数，看起来很复杂的样子

一点也不复杂,就是把画面放大两倍,转90度,用 SangNom处理一遍,再转回来,再用 SangNom处理一遍,然后resize回来,再用unfilter锐化一遍
