It's not really a software patent if you think a bit about it ;-) It's definetely more related to typography, the lcd displays and alike.

Not sure if I get this right, but it says that it's in a "Pending" state which means it's not yet "Granted", which means we can still use it legally for a while, or maybe even for a longer if it gets "Not valid" state eventually :D

So what it means is that currently it's probably legal to use these patches for at least those who live in EU.

Still, we don't know if the patches use exactly the same technique as described in this Adobe's patent grant request you linked here.

(And BTW basically you are right, luckily the software patentes are not being granted in EU _yet_. But that's pretty OT anyway.)

Re: Improved subpixel font rendering

I want to see the person who sues you for using subpixel rendering under Linux. Seems ridiculous to me - I am not even using the Adobe algorithm I assume.

Re: Improved subpixel font rendering

I've just noticed this explanation uploaded by David to his site/repo (dunno how to call it).

In the end part we can see some interesting note:

I have even provided patches to do just that a loooong time ago; for some reason, these have never been integrated by the respective library maintainers. I hope some day they'll wake up (though my hope is pretty dim). I suspect that Linux distribution packagers are already applying these patches though...

IMO, that could be argument for merging David's patches with Arch packages. We don't bother about patents too much, do we?

As an alternative for a slightly different look, there's now Arch packages for the Gentoo Xeffects versions of libxft and cairo smile

Re: Improved subpixel font rendering

Wow! Just discovered this thread and installed the -lcd versions from community. The difference is astonishing. Thanks so much! (Haven't yet tried the new Gentoo versions in AUR).

Edit: Just installed the -xeffects versions from AUR, and they work well. Seems to be a little less "fake color" blur behind the text than with -lcd (not that there's much with -lcd). YMMV, I'm sure.

patch is in the core repository. Do a pacman -Syy to force update of the database before running pacman -S patch.

LOL, install yaourt from AUR and then install the packages. It will tell u exactly what u need to remove. Sometimes people forget when making aliases to certain programs. Don't concern yourself with that, just install yaourt.


yaourt -S libxft-xeffects

...

checking dependencies...

that easy.
