The subject of this thread is FALSE. I wonder whether the person starting the thread even read the page he quoted. All the Qt page is saying is that they now implement all the different subpixel filters that FreeType supports (in a patent-infringing build). There is NO new algorithm involved. Go read it for yourself:

Any kind of subpixel filtering is covered by those patents. Just stop it already. behdad Your pissed off text stack maintainer
