Disable it - it won't help in the slightest. You can see from the ebuild what it does. |

How did you manage to get this overlay ebuild working, so that the overlay ebuild is used instead of the one from the default portage tree?
Code: | root@gentoo_ws:~ # layman -a lcd-filtering

Reading category 154|154 (100%) EMPTY! |
So layman -a did succeed but it seems to be empty
Edit: i forgot to update the /etc/make.conf
So still the issue with fonts like Verdana, Arial etc. that they look messed up.
On my old debian system i used dpkg-reconfigure fontconfig and the settings that made everything fine were:
1. Hinting: Native (instead of Automatic or None) 2. Subpixel: Automatich (instead of Always/Never, although it doesn't affect firefox) 3. Bitmapfonts: yes (without yes fonts like terminus wont work).
So i made two screenshots to show the difference.
Screenshots with Gentoo:
http://andi.wootstube.de/up/2010-08-25-024230_1280x1006_scrot.png
http://andi.wootstube.de/up/2010-08-25-024317_1280x1006_scrot.png
Screenshots with Debian:

http://andi.wootstube.de/up/2010-08-24-220933_1280x1006_scrot.png
corefonts are installed on both system.
Edit2: Another confusing fact, on my gentoo system at work i have the same settings and the fonts are much better. What i found out that xdpyinfo tells me that the 19" LCD at work has 96x96DPI but the 19" LCD has 85x86DPI although both are running on 1280x1024. May this be the issue for the fonts?
Edit3: A nice tool to see what effects hinting and antialiasing will have is "gwaterfall" (you need to get the source from debian). It's just weird that it needs to be started by root to get hint/antialias switch working. Maybe this will help some of you with generating a suitable font.conf.
Ah the issue with root is, that gwaterfall won't work when you have a .fonts.conf, so move it to test font settings.
ok i found the problem but i have no good fix. Althought the FontPath for corefonts is the first in my xorg.conf the corefonts aren't used as first choice.
Code: | Section "Files"
FontPath "/usr/share/fonts/terminus"
FontPath "/usr/share/fonts/corefonts"
FontPath "/usr/share/fonts/100dpi/"
FontPath "/usr/share/fonts/75dpi/"
FontPath "/usr/share/fonts/misc/"
...
EndSection |
But when i use lsof:
Code: | root@gentoo_ws:~ # lsof | grep fonts
firefox-b 17590 andi mem REG 253,5 139640 1976947 /usr/share/fonts/corefonts/verdana.ttf

firefox-b 17590 andi mem REG 253,5 5063 1880230 /usr/share/fonts/terminus/ter-112n.pcf.gz |
So now Courier from corefonts is used to render the code section here in the forum. At least some are working like arial and verdana.
Is there anything else i have to check except xorg.conf?
Chromium is doing it right, lsof says /usr/share/fonts/corefonts/cour.ttf
I tried moving all the /usr/share/fonts directories except the corefonts and so i can force corefonts/cour.ttf but that seems to be the right way.
I also tried a fresh archlinux install in vbox and there it's working out of the box, here the comparison (left gentoo, right arch):
http://img178.imageshack.us/img178/4817/201008252133322560x1024.png
you can see the difference on the "@" for example.

ok i think i fixed it, at least most of it. I switched back to firefox instead of firefox-bin. Although i don't know what's the exact difference.
But there seems to be a bug with "courier" in corefonts. The "code" segment here uses courier then courier new then monospace. If i forbid using courier firefox switches to courier new and it's looking fine. If i look at lsof, firefox doesn't user courier from corefonts but he uses courier new. Well cour.ttf is used when i force courier new, when courier is used lsof prints no relation to the corefonts folder so i guess it must be one of the pcf.gz from the misc folder.
So i want to have courier and maybe courier new replaced, so i tried:
Code: |
</match>
<!-- Replace Courier New with a better-looking font -->
<match target="pattern" name="family">
<test name="family" qual="any">
<string>Courier New</string>
</test>
<edit name="family" mode="assign">
<!-- Other choices - Andale Mono, Courier New, Luxi Mono, Bitstream Vera Sans Mono -->
<string>Bitstream Vera Sans Mono</string>
</edit>
</match>
<!-- Replace Courier New with a better-looking font -->
<match target="pattern" name="family">
<test name="family" qual="any">
<string>Courier</string>
</test>
<edit name="family" mode="assign">
<!-- Other choices - Andale Mono, Courier New, Luxi Mono, Bitstream Vera Sans Mono -->
<string>Bitstream Vera Sans Mono</string>
</edit>
</match>
|
But firefox ignores this, when i use the fontfinder addon and forbid courier/courier new it's working. And yes bitstream is installed
Edit:
The wrong courier is /usr/share/fonts/default/ghostscript/n022003l.pfb so Nimbus Mono L was mapped to Courier cause of 30-metric-aliases.conf. I think this should be removed from default fontconfig settings. |

That won't use the system cairo - need --enable-system-cairo
Your fontconfig rant makes very little sense.
I will repeat again, Infinality's font rendering is superior to Ubuntu's, making most font substitutions unnecessary, because Infinality's font rendering makes the non-substituted fonts look good enough. |

May be but this fixed the issue with Nimbus Mono L used instead of switching to Courier New in Firefox. Chromium does this without changing 30-metric-aliases.conf
PaulBredbury wrote: | I will repeat again, Infinality's font rendering is superior to Ubuntu's, making most font substitutions unnecessary, because Infinality's font rendering makes the non-substituted fonts look good enough. |
And i tried this patch and it looks nice, but the above problem with Nimbus Mono L for Courier was still there.
Edit:
Ok i found out, that with the patch "lcdfilter" from lcd-filtering overlay it looks worse :/
It's not that sharp.
freetype etc. with lcd-filtering overlay patch:
http://andi.wootstube.de/up/2010-08-27-144009_1280x1006_scrot.png
freetype etc. without the patch:
http://andi.wootstube.de/up/2010-08-27-144404_1280x1006_scrot.png
disabled 30-metric-alias.conf:
http://andi.wootstube.de/up/2010-08-27-144656_1280x1006_scrot.png
As you can see with gentoo default settings it looks sharper then with the patch from the overlay and disabling 30-metric helps for the code segment.
Although the rest of the 30-metric.conf is good for arial, so i just deleted the courier part. |

Hello,
so You use only /etc/fonts/local.conf and and your ~/.fonts.conf after Infinality patch?
thanks |

Well, there's still the configuration from fontconfig's default install, in /etc/fonts/conf.d/ (as symlinks) which I don't mess with:

Yeah, it looks better - and gotten from just removing one line of code

Just one more question.
Do You use some packages from lcd-filtering overlay or only default gentoo repository plus patched freetype?
I've tried that patch, it looks really nice, but don't know if is it using by all application.
Thanks |

I use Lunar Linux, and for now am still using my own versions of fontconfig, libXft and cairo which include Ubuntu's patches (and my cairo-respect-fontconfig.patch) - basically equivalent to those in the lcd-filtering overlay.
Edit: You need fontconfig, libXft and cairo from the lcd-filtering overlay, otherwise cairo *won't* use the patched freetype's improved rendering.

Here's a freetype-2.4.2-infinality-20100904.patch all-in-one patch I've made for freetype 2.4.2 - take a look at it, to see what it contains.
I still also recommend adding:
sed -i -e "s:0x10, 0x40, 0x70, 0x40, 0x10:0x1c, 0x38, 0x55, 0x38, 0x1c:" src/base/ftlcdfil.c
Old stuff:
freetype-2.4.2-infinality-20100903.patch
freetype-2.4.2-infinality-20100828.patch
Old patch
Here's an all-in-one patch I've made for freetype 2.4.0 (also works with freetype 2.4.1)
Edit: Got "hinting" vs "filtering" confused
Edit2: Here's the patch for freetype 2.4.2
Edit3: Added upstream patches. |
Is there any guide or something? I've edited freetype ebuild from lcd-filtering and tried to apply the patch (freetype-2.4.2-infinality-20100904.patch), but when emerging, it always fails.
EDIT: I managed to build freetype with infinality patch (lcd-filtering ebuild + infinality). What do I've to do now? Thanks |

I think after pacth of freetype You should use .fonts.conf from PaulBredbury or /etc/fonts/local.conf from Infinality's web. Also You have to use "lcdfilter" flag for x11-libs/cairo and it's all(same for x11-libs/libXft if You use lcd-filtering overlay) |

I just updated the following packages from the lcd-filtering overlay:
Code: |
##LCD Filtering Overlay
media-libs/fontconfig lcdfilter -cleartype
media-libs/freetype lcdfilter -cleartype
x11-libs/cairo glitz lcdfilter -cleartype
x11-libs/libXft lcdfilter -cleartype
|
Whether or not this is a horrible combination of use flags I would like to know. Also, what should my .fonts.conf look like? _________________ Who shall guard the guards? |

Yet another patch update. Among a few enhancements, this one also removed a couple things I think you guys had enabled in modules.cfg, just so you are aware.

Is lcd-filtering still maintained? Maybe some of you will ask for commit rights and will push updates because looks like owner of this overlay does not (for some reason) update it. |

Can someone please tell what patch needs to be applied on top what's in portage at this time?
Which packages are to be modified? freetype, libXft. Anything else? |

People seem confused, so let's recap. To get the current state-of-the-art in font rendering:
1. Apply Infinality's freetype patches (example: pross overlay). Edit: Also consider the Gibson filter - sed one-liner, which I still think looks smoother than the default.
2. Apply Ubuntu's patches to fontconfig. (This step doesn't seem to be strictly required, but this would be the right time to do it.)
3. Apply Ubuntu's patches to libXft, so that apps which use libXft will use the better rendering.
4. Apply Ubuntu's patches to cairo, so that apps which use cairo will use the better rendering. Also apply my cairo-respect-fontconfig.patch, so that ~/.fonts.conf isn't occasionally ignored.
5. Use Infinality's fontconfig rules, in /etc/fonts/conf.d/ or as ~/.fonts.conf
6. For completeness, set up ~/.Xresources - this is the "backup" settings for crappy/old programs which don't use fontconfig.
7. Restart your apps (e.g. firefox) and marvel at the beautiful fonts.
Edit: Clarified why ~/.Xresources is used.

Thank you very much Paul for this splendid summary!
Can't Infinality's freetype patches not be merged in the lcd-filtering overlay (like all the other patches)? Otherwise it's quite some hazzle to get all the bits & pieces together from different overlays and keep them uptodate ...
Kindly yours

Tried this and took screenshot to compare against cairo with cleartype. Quality isn't bad, but as much as I tried, cleartype seems to produce clearer, crispier fonts on my LCD. I am sticking with cleartype. |
