Xft Hack Improves Antialiased Font Rendering
Eugenia writes: "Font antialiasing first made its way to XFree through Qt/KDE only a year ago and GTK+/Gnome followed some time after. Even with the latest version of Freetype 2.08, which reportedly brings better quality, the result is still not up to par with the rendering quality found on some commercial OSes. David Chester has hacked through the Xft library and he achieved an incredibly good quality on antialias rendering under XFree86. With this hack, at last, XFree can deliver similar aesthetic results to Mac OS X's or Windows' rendering engines. Check the two brand-new screenshots ('before' and 'after') at his web page and notice the difference with your own eyes."
(half off-topic, I know).
It's like the text is always too small, too large, or not the one the developer intended.
Not to troll, but this is exactly the kind of thing that has much more effect than technical people believe.
Is it something in the design? The freely available fonts?
Why isn't font rendering done properly in the X server itself, where font rendering originally was done? Why must it be done client side?
I mean, the X server already knows what kind of visual you're trying to render to, so it's really just a question of getting the X server to pick up the necessary font information (transparency information at the edges of the letters if you insist on the X server itself not understanding how to render fonts). And the types used for the font rendering calls are all opaque anyway, so it shouldn't matter whether or not the font structure in the GC (on the server) stores additional information about the font being rendered, right?
All it would take in addition to the improved font rendering code in the X server is the definition of a new font server protocol that allows the transmission of more than just bitmap information to the X server from the font server and you'd be done, right?
So why isn't this being done instead of these client-side hacks that require magic rendering extensions (which are quite cool in and of themselves, but why should the client have to have a full set of fonts stored locally in order to do antialiased text?) ? The biggest advantage of this scheme by far is that you don't have to have any magic support for antialiased fonts in your toolkits: you get antialiased fonts for everything no matter what toolkit it's using (even Athena widgets would have antialiased text if the antialiased font rendering were done entirely server-side).
Or is this already what's being done, but I somehow missed it?

Fact 1: Hinting improves font legibility at smaller sizes.
Fact 2: Freetype doesn't interpret the bytecodes in the fonts that are needed for proper hinting because of patents detained by Apple.
Fact 3: It uses an alternative bytecode "guesser". People may or may not like it, even though it usually improves legibility. This Canadian dude (I have the right to use this term because I am myself a Canadian dude ;)) only disabled the bytecode "guesser" because he didn't like it. Fine.
Fact 4: Rather than disabling the bytecode "guesser", enable the patented bytecode interpreter. Remember, this is illegal if you live in the U.S. and haven't licenced the patents from Apple.
For your enjoyment, I've made RPMs for Mandrake 8.1 and Redhat 7.2 of the Freetype library with the patented bytecode interpreter enabled.
