bi3l, thanks for your great work! Since you host the scripts in sourceforge, isn't there a way to set up a Subversion reporitory there, so we can update easily? I think sf.net gives you svn ability...
Thanks!!

If you go with Subversion, you might as well make your overlay accessible with layman.  |

Well, yes, that's the next step, but I thought each step at the time.

| Sorry, but no, I won't setup an overlay in the subversion repository of this sourceforge project: it's already used for OGMRip. |

OK, no problem. It's nice to have you backing up these patches!

| Copying bi3l's libXft-2.1.12.ebuild to libXft-2.1.13.ebuild appears to compile libXft 2.1.13 with the newspr patch just fine. |

You no longer need to patch Freetype or Fontconfig, only libXft and Cairo.
The LCD configuration options were merged into fontconfig by Keith Packard sometime in the 2.5.9x timeframe (2.5.93 I think).
It is vaguely worth mentioning the Ubuntu patches are somewhat out of date. The latest rework of the LCD filtering patch for Cairo was done by Sylvain Pasche when he posted a patch back in January. Afaik, the Ubuntu patch for Cairo predates this.
The cairo patch for libXft is fine as far as I know but won't compile against latest (now upstream) version (2.1.13) of Fontconfig unless you make a 2 line change replacing instances of FC_LCD_FILTER_* constants with FC_LCD_*.
I have my own versions of these patches, they can be found here. The broken-out folder contains the Cairo patch patch from Sylvain and a 'reject-fix' patch for Cairo 1.6.4, these are just there so others can check the patch if they wish.
My patches are named such that they work with bashrcng's patching module (It is what I use), so you can use the ebuilds already in portage.

The patches against fontconfig and freetype does not add lcd filtering (as you said, it's already there). They mainly fix things in the code, modify some conf.avail files, add new ones, and change the default ones in conf.d.
Your patches against libXft and cairo and those provided in the tarball are very similar. |

You have to add EAPI="1" at the top of the two ebuilds that are missing them. The other two have that line, but the ones with the error are missing it. |

Here's the difference between no subpixel filtering and subpixel filtering turned on with these patches. It's somewhat subtle but I still think it's an improvement. I'm not sure why but with Ubuntu the text looks slightly 'bolder'.
Turned off: http://www.aphax.nl/images/lcd-off.png
Turned on: http://www.aphax.nl/images/lcd-on.png
The difference between subpixel filtering and normal rendering without these patches is even smaller and doesn't seem to improve anything. |

It is strange that not many people talk about this patches and lcdfiltering in g eneral. Fonts are so much better with it. In my case I can't stand fonts without it. And here I have problem. I upgraded to libXft-2.1.13 and I do not know how to compile it with all this patches etc. Can you please tell me how to use this patches in ebuilds?

Most people are using pre-rolled distributions (like Ubuntu) that already have LCD filtering patches applied. That's why nobody talks about this stuff; for the majority of people the fonts already look good.
bi3l's overlay already contains a patched ebuild for libXft-2.1.13. Just extract the tarball into your local overlay, enable the "newspr" USE flag for libXft, and re-emerge libXft.- mkdir -p /usr/portage/local/bi3l
- cd /usr/portage/local/bi3l
- tar -xjf ~/gentoo-lcd-filtering.tar.bz2
- echo 'PORTDIR_OVERLAY="${PORTDIR_OVERLAY} /usr/portage/local/bi3l"' >> /etc/make.conf
- echo 'x11-libs/libXft newspr' >> /etc/portage/package.use
- emerge --oneshot x11-libs/libXft
Edit: Of course, you also need to re-emerge media-libs/freetype and media-libs/fontconfig with the "ubuntu" USE flag enabled. You also probably will want to re-emerge x11-libs/cairo with the "newspr" USE flag enabled. |

You mean the difference between lcddefault and lcdlegacy? Well, the colours are arranged differently. Choose whichever looks better.
Open up the screenshot in e.g. eog and zoom in - notice the colours around the fonts. Right there is the proof. They effectively improve the resolution of fonts on LCD displays, by exploiting the fact that LCD pixels are split into 3 blocks - red, green and blue ("RGB"), in a consistent layout all over the screen. Yes it's subtle, and people with bad eyesight, bad monitors or badly configured software (e.g. wrong DPI settings or RGB in different order) might not be able to see what's right in front of their eyes. Then there's the choice of fonts, the style of LCD rendering ( lcddefault, lcdlight, lcdlegacy) and the huge flexibility possible in /etc/fonts/ and ~/.fonts.conf - here's mine.

Major distros like Fedora and OpenSuSE are still scared of the potential of getting sued. But that's easily fixed [/shameless plug] |

What do you mean by lcddefault and lcdlegacy? In any case I find that my fonts look much better with the patches so that's what I'm using |

I don't see it. Here http://ogmrip.sourceforge.net/misc/gentoo-lcd-filtering.tar.bz2 we have only 2.1.12 version.

Yes, I already found this about copying.
It works now (it needed digest though).
I have my fonts back, and I am happy about it. Thank you.

To make a newspr-enabled ebuild for the newly released x11-libs/cairo-1.6.4-r1:
| Code: | emerge --sync
cd /usr/portage/local/bi3l/x11-libs/cairo
cp cairo-1.6.4{,-r1}.ebuild
wget -O- 'http://home.mattwhitlock.com/~mattw/cairo-1.6.4-r1.ebuild.patch' | patch
cp /usr/portage/x11-libs/cairo/files/cairo-1.6.4-libpng-api-change.patch files/

Could you please post the resulting ebuild? Does this cairo ebuild have an newspr use flag? I'm confused. /edit: fixed, is there a maintained overlay which contains the ebuilds?
We should start updating the wiki or crate a new entry for this, what do you think?
My problem atm is btw that since some updates the fonts in firefox don't look perfect any longer.

I made my patch against bi3l's ebuild, which you can find in his overlay tarball here: http://ogmrip.sourceforge.net/misc/gentoo-lcd-filtering.tar.bz2
bi3l's ebuild of cairo does have the newspr flag. |
