I'm not one of those three, but I'll just chime in anyway and say that I agree with Benoit that, at least in the example he gave, it's very obvious that the non-hinted version looks much better. I'm not trying to troll here, but come on, in some places the hinted one is hardly readable, the characters are all jumpy; e.g. the 'T' in the very first word. I don't know if this is a bug in the hinting or just the way it's supposed to look. Anyway, this doesn't make me a "follower" of Benoit; I'm just calling it like I see it ;) Cheers, Elvis > > Comments? > > Albert > >> >> Benoit >> > > _______________________________________________ > Okular-devel mailing list > Okular-devel@kde.org > https://mail.kde.org/mailman/listinfo/okular-devel > _______________________________________________ Okular-devel mailing list Okular-devel@kde.org https://mail.kde.org/mailman/listinfo/okular-devel
