Sir, the subject is not false. You may be a text-stack-maintainer, but I am not a moron. >From the article: ----- "However, since Qt4 was released, Freetype has added support for doing subpixel rendering and filtering itself, along with several settings for which filter to use. In Qt 4.5 we will use Freetype’s filtering if available..." ----- >From this, we clearly see that Qt has only started to use Freetype's filter, in a version of Qt that Fedora hasn't even shipped to F10 yet. Ergo: Qt has actually had its own filtering code independent of Freetype for some time (I imagine analogous to Xft and Cairo in those articles from David Turner the guy above linked to). And, here's more: ----- "Note that the filtering we use in Qt 4.4 and earlier is pretty much the same as Freetype’s default filtering..." ----- They obviously have developed their own filter code (see above), sometime before Freetype removed their own built-in LCD-specific filtering. The final result is apparently comparable to Freetype's old (patent-infringing) filters. If you want to double check me, then actually try _running_ a Qt program in Fedora with RGB rendering on. You'll notice the filtering looks a heck of a lot different than GTK programs. I am not trying to be deceptive or waste anyone's time. I genuinely thought this was something to look into. Yes, I could be wrong and Qt's filter could also patent-infringe. But I have already mentioned all of this. I am _not_ wrong that Qt has their own independent filtering code. I am sorry I started the discussion. Patent law is not my forte, but I did come in with _some_ understanding of how the X text stack works. -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
