hmm linear interpolation sucks IMHO, why dont u use some filter like (-9a + 111b + 29c -3d + 64)>>7 or (-a + 14b + 3c + 8)>>4
Because I'm lazy and don't know how to make this perform decent in mmx... i cant imagine any tricks beyond a simple unpack, multiply, add, ..., shift,

Also, I'm a bit skeptical of wider filters with with sharp edges (common in anime)... What do you think about this?
yes, wide filters will create ugly wave effects around edges (just try -sws 8) but 3tap/4tap isnt wide, and short filters suck too for edges as they blur them [...] -- Michael screen[y][x] ^= cursor[cy][cx]; (violates patent #4,197,590) median(mv[y-1][x], mv[y][x-1], mv[y+1][x+1]); (violates patent #5,905,535) buf[i]= qp - buf[i-1]; (violates patent #?) for more examples, see http://mplayerhq.hu/~michael/patent.html stop it, see http://petition.eurolinux.org & http://petition.ffii.org/eubsa/en
