| I've already joined the devnull team. All the ebuild of the lcd-filtering overlay are in devnull testing. |

| But there is no cairo-respect-fontconfig.patch in devnull. And in fact no cairo ebuild at all. |

| I didn't say they are in devnull, I said they are devnull testing. |

| Thanks for clarification! And how can I add devnull testing overlay? |

No need for. I have updated the devnull overlay.
We do now have all font ebuilds with cleartype AND ubuntu patches/useflags.
No useflag is defaulted. Both useflags can't be active the same time.
Thanks to bi3l for his great work. Enjoy :) |

That's great. Many thanks. 
BTW: The first part of this patch causes a huge improvement in pdf rendering here (I'm using the »cleartype« useflag) .
( I've changed »cairo_font_options_set_hint_style (options, CAIRO_HINT_STYLE_SLIGHT);« to
»cairo_font_options_set_hint_style (options, CAIRO_HINT_STYLE_NONE);« because it looks better to me).

I've tried this patch but don't see any improvement. Can you mail me (billl at users.sourceforge.net) a pdf which is better rendered with the patch ? |

Every pdf I've tested is rendered better with this patch... 
It's the difference between grayscale- (the default in evince) and subpixel- rendering,
which this patch enables.
(Try these for example: http://arxiv.org/list/gr-qc/new )
BTW I get color fringes when I use this patch with the "ubuntu" USE flag. No problems with "cleartype".

Upper left: cleartype. Lower right: ubuntu.

As you'll see, ubuntu has a little bit more contrast.

Cleartype works fine for me.

Thanks! But why cleartype was chosen for portage (cairo in portage has cleartype patches and USE flag)? |

I personally appreciate having the lcd-filter overlay, so I don't have the huge number of overridden packages that devnull would contribute. Portage really needs an ability to mask and unmask packages based on which overlay they're coming from. |

If you are afraid about the -9999 ebuilds, they're all hardmasked ;) |

I get colour fringes in general with "ubuntu". But then again, I use the 'slight' hinting option, "ubuntu" is designed for well hinted fonts. Poppler disables font hinting totally -- hence why you'll get colour fringes with it. "cleartype" handles non/slight hinting a *lot* better.

Hello,
I have a HP LP2275W LCD monitor. I use fontconfig/cairo/freetype/libXft with cleartype flag and RGB subpixel enabled. Almost everything looks great, but in some apps black font on white background looks too green. For example in gedit font looks OK, but same font rendered in gnome-terminal looks strange (http://images40.fotosik.pl/71/1f7a26d325440b56.png).

thanks for the great work - my fonts look great!
just one question, however - is there a resolution for the problem of fonts being too bold (facebook's home page, yahoo mail, etc)? i tried doing this:
| Code: |
<?xml version='1.0'?>
<!DOCTYPE fontconfig SYSTEM 'fonts.dtd'>
<fontconfig>
<!-- Disable hinting for bold fonts -->
<match target="font" >
<test compare="more" name="weight" >
<const>medium</const>
</test>
<edit mode="assign" name="autohint" >
<bool>false</bool>
</edit>
</match>
</fontconfig>
|
and enabling user config, but it doesn't make much of a difference. bold fonts look awesome throughout, it's just a handful of webpages (facebook isn't too bad even, it's just yahoo mail not being able to know what messages are new versus which are read).
thanks! |

i have it set up so it doesn't autohint bold fonts, as follows. instead of definining it locally make it global by making a new file in /etc/fonts/conf.avail/
| Code: |
paul@s021765 ~ $ cat /etc/fonts/conf.avail/99-disable-hinting-on-bold-fonts.conf
<?xml version="1.0"?>
<!DOCTYPE fontconfig SYSTEM "fonts.dtd">
<fontconfig>
<!-- Disable hinting for bold fonts -->
<match target="font">
<test name="weight" compare="more">
<const>medium</const>
</test>
<edit name="autohint" mode="assign">
<bool>false</bool>
</edit>
</match>
</fontconfig>
|
now all you have to do is (as root), eselect fontconfig enable ... with whatever number the file has.
i don't quite get why your version won't work (the xml file seems identical) but this should definitely. |

Any news on the poppler patches for either the devnull overlay or lcd-filtering. Be interesting to toy with them.

| media-libs/freetype-2.3.9 appears to compile with the cleartype patches with just a simple rename of the 2.3.8 ebuild. |

| Yup. It compiles cleanly but I haven't restarted X yet. |

Okay, tell me wheter it works and if it does, I'll add it to devnull (or you can do it if you want). |

|
|
First of all, a shout of thanks goes out to both ocin and bi3l for their efforts. I have been using this patchset lineage since xeffects and newspr, but was manually updating it after xeffects left. I have now started using the devnull overlay.
I now have things working the way I want. I found that cleartype was softer with less color fringing with my setup, so I am using it instead of ubuntu. Here is my full config in case it will help anyone:
Added devnull overlay
Added cleartype use flag to /etc/make.conf
Masked the new freetype in portage until it lands in devnull
/etc/portage/package.mask
| Code: | >=media-libs/freetype-2.3.9
|
Enable byte-code interpreter and disable sse2 in pixman because I use the stable gcc 4.1.x
/etc/portage/package.use
| Code: | media-libs/freetype -bindist
x11-libs/pixman -sse2
|
Unmask the testing versions of the packages
/etc/portage/package.keywords
| Code: | x11-libs/cairo
x11-libs/libXft
media-libs/fontconfig
media-libs/freetype
x11-libs/pixman
|
eselect fontconfig list
| Code: | Available fontconfig .conf files ( * is enabled ):
[1] 10-antialias.conf *
[2] 10-autohint.conf
[3] 10-hinting-full.conf *
[4] 10-hinting-medium.conf
[5] 10-hinting-slight.conf
[6] 10-hinting.conf *
[7] 10-no-sub-pixel.conf
[8] 10-sub-pixel-bgr.conf
[9] 10-sub-pixel-rgb.conf *
[10] 10-sub-pixel-vbgr.conf
[11] 10-sub-pixel-vrgb.conf
[12] 10-unhinted.conf
[13] 20-fix-globaladvance.conf *
[14] 20-unhint-small-vera.conf *
[15] 25-unhint-nonlatin.conf
[16] 30-metric-aliases.conf *
[17] 30-urw-aliases.conf *
[18] 40-nonlatin.conf *
[19] 45-latin.conf *
[20] 49-sansserif.conf *
[21] 50-user.conf *
[22] 51-local.conf *
[23] 60-latin.conf *
[24] 65-fonts-persian.conf *
[25] 65-khmer.conf
[26] 65-nonlatin.conf *
[27] 69-unifont.conf *
[28] 70-no-bitmaps.conf *
[29] 70-yes-bitmaps.conf
[30] 80-delicious.conf *
[31] 90-synthetic.conf *

Set DPI for my monitor and ensure autohinting is off
/etc/fonts/local.conf
| Code: | <?xml version="1.0"?>
<!DOCTYPE fontconfig SYSTEM "fonts.dtd">
<!-- /etc/fonts/local.conf file for local customizations -->
<fontconfig>
<match target="font">
<!-- Turn off Autohinter to use Byte Code Interpreter -->
<edit name="autohint" mode="assign"><bool>false</bool></edit>
</match>
<!-- Set dpi -->
<match target="pattern">
<edit name="dpi" mode="assign"><double>85</double></edit>
</match>
</fontconfig>
|
And my matching Xresources
~/.Xresources
| Code: | Xft.autohint: false
Xft.hintstyle: hintfull
Xft.hinting: true
Xft.antialias: true
Xft.rgba: rgb
Xft.dpi: 85
|
I restarted X here, and it looks beautiful again. You can check that the Xresource changes are working with | Code: | | xrdb -query | grep -i xft |
Cheers,
