bi3l, fontconfig-2.7.1 is available in portage, can you bump it in the overlays please? :)

Seems like I have problems when using devnull's ebulds with USE flags "-cleartype ubuntu"

I'm unable to merge some packages, i.e. mozilla-thunderbird, seamonkey

emerge fails complaining about undefined references:

something's wrong with devnull's libXft (fontoconfig/freetype)?
I didn't looked thoroughly through ubuntu patches yet

p.s. when using cairo, libXft, fontconfig and freetype with default USE "+cleartype" I have no problems emerging this packages

Do you have fontconfig installed? It's defined in /usr/include/fontconfig/fontconfig.h

definitely yes
as I said I have all 4 packages (cairo, libXft, fontconfig and freetype) from devnull's overlay installed
the only difference is in this two USE flags

BUT
when emerged with default flags (+cleartype) they make no harm
and with USE "-cleartype ubuntu" I get these errors

IvanMajhen · Post by **IvanMajhen** » Fri Aug 21, 2009 5:00 pm

Is there a bug in kickoff luncher? (kde 4.3)

All my fonts are rendered exactly the same, but fonts in kickoff look like they are not using lcddefault setting...

The "cleartype" USE flag of freetype in devnull doesn't do anything, so it might as well be removed.

The one solution I used is:
1. quickpkg devnull's cairo, libXft, fontconfig and freetype packages (emerged with "-cleartype ubuntu"), move them to some other dir on HDD
2. re-emerge this packages with standard use flags ("+cleartype -ubuntu")
3. quckpkg this packages
4. emerge all needed packages (i.e. mozilla-thunderbird)
5. change again flags to "-cleartype ubuntu", and then emerge -K all packages from 1st step

everyting works fine for me, but it's just workaround, so next time You'll have the same problem

P.S. I know, it's dumb solutuion, but it works, don't blame me...

Think I may have asked this before but here goes:

I have cairo-1.8.8 / libXft-2.1.13 / freetype-2.3.9-r1 from devnull with "cleartype" use flag. Also have fontconfig-2.6.0-r2 (from devnull with cleartype use flag). Switched to fontconfig-2.7.2 (also from devnull with cleartype use flag). For the exact same configurations, using fontconfig-2.7.2 makes my fonts resemble their pre-devnull days (ie, looks much worse then with fontconfig-2.6.0-r2 ), so I keep going back to fontconfig-2.6.0-r2. Any idea why this should be the case? Should I switch to the ubuntu use flag?

Freetype 2.3.11 is in portage, can we get the overlay updated too?

Thank you for doing this!

bi3l · Post by **bi3l** » Sat Oct 17, 2009 12:50 pm

Updated freetype to 2.3.11 and libXft to 2.1.14 in both lcd-filtering and devnull.

I still have problem with skype font hinting under amd64...
it is always the same user, same $HOME...

under ~x86 gentoo and arch the fonts in skype look OK, hinting is fine.
under ~amd64 the hinting looks different (ugly) and I can't bring it to look the same
as under the other two systems

tried different hinting setting in xfce, played with qtconfig, no improvement

Please advice what else should I try... since I use skype daily, it is getting on my eyes... thank you

Firefox 3.5.6 now strictly depends on cairo 1.8.8 [previous 3.5.x versions were compiling fine with 1.8.6 after change in ebuild], so looks like I'll have to deal with this new cairo. This is how text looks like with:
- cairo 1.8.6,
- freetype 2.3.11,
- fontconfig 2.8.0,
- libXft 2.1.14.

http://manwe.rootnode.net/cairo1.png

So everything in the newest versions, except cairo. Config:

Code: Select all

# cat /etc/fonts/local.conf
<?xml version="1.0"?>
<!DOCTYPE fontconfig SYSTEM "fonts.dtd">

        <include ignore_missing="yes">/home/manwe/.fonts/vistafonts.conf</include>

        </match>

        <match target="font">

        <match target="font">
                <edit name="lcdfilter" mode="assign"><const>lcddefault</const></edit>
        </match>

        <selectfont>
                <rejectfont><pattern><patelt name="fontformat"><string>Type 1</string></patelt></pattern></rejectfont>
        </selectfont>

        <match target="pattern">
                <test qual="any" name="family"><string>Courier</string></test>
                <edit name="family" mode="assign"><string>Consolas</string></edit>
        </match>

        <match target="pattern">
                <test qual="any" name="family"><string>Courier</string></test>
                <edit name="family" mode="assign"><string>Consolas</string></edit>
        </match>

        <match target="pattern">
                <test qual="any" name="family"><string>Helvetica</string></test>
                <edit name="family" mode="assign"><string>Helvetica CE</string></edit>
        </match>
</fontconfig>

Now let's upgrade to cairo-1.8.8: http://manwe.rootnode.net/cairo2.png . Ugly as hell, "g" is moves to the left, "m" is asymmetrical, etc. Disabling hinting:

Code: Select all

<edit name="hinting" mode="assign"><bool>false</bool></edit>

helps with shapes of the letters, but makes them to blurry, most visible in the menu: http://manwe.rootnode.net/cairo3.png . I've tried messing with hint, autohint and lcdfilter but didn't get proper rendering, like with cairo 1.8.6. Any ideas?

Let's not forget about pixman, which cairo depends on, even though we don't need to patch pixman for the improved LCD font rendering.

pixman is currently at 0.16.4. Recompile cairo after upgrading pixman, to follow the dependency order.

See blurry fonts. Add entries to ~/.fonts.conf for specific font renderings that you don't like. This is the hassle that we have to go through, to set up fonts as we like them, on our hardware. Here's my ~/.fonts.conf as an example.

Why 0.16.4 i newer than 0.17.2?

I've started messing with my config, but couldn't get look like with cairo 1.8.6. Then tried your config and... it's great

Even numbers are the "stable" branch, odd numbers are the "unstable" branch.

Linux is unstable enough already, without deliberately using branches labelled "unstable". Example problem with 0.17.2
