Don't be so trusting. People can and do screw up compilations in every way possible. A recompilation won't hurt, and might fix the problem.

As a simple example, if a big patch is added to freetype, then "emerge cairo" is run, Portage won't know that freetype should be recompiled first.

Use eselect fontconfig, as some conf files were changed.

I have reseted whole fontconfig configuration and applied again as described in wiki, also tried rebuilding firefox, no effect.

*edit*
Ive downgraded fontconfig-2.9.0 to fontconfig-2.8.0-r2 and it helped.

Then the patch should be controlled by a USE flag or the version of freetype should be bumped to -r1 or something… either way, cairo's dependencies should require either the USE flag or new version if necessary. Since bi3l's ebuilds require the proper "lcdfilter" USE flags, everything will be built in the correct order.

Same solution here.

You saw and tried the new 11-lcdfilter-* rules in fontconfig did you?

Try without the opengl USE flag. cairo 1.12.2's configure contains:

"'--- The OpenGL surface backend feature is still under active development and
--- is included in this release only as a preview. It does NOT fully work yet
--- and incompatible changes may yet be made to OpenGL surface backend
--- specific API.'

Anyway, fontconfig 2.9.0 works fine for me, with cairo 1.12.2 and the firefox 12.0 patch I mentioned earlier in this thread.

I compile cairo with:

Code: Select all

--disable-static --disable-xlib-xcb --enable-tee --with-x

You're wright.
11-lcdfilter-* was not activated.

Er, what magic do you think it/they contain, that isn't already in Infinality's fontconfig file?

Without this enabled you get broken fonts as mentioned earlier in the page. If you follow these instructions then you will be stuck unless you notice that some of the filenames have changed.

all ebuilds in lcd-filtering overlay should switch to virtual/pkgconfig dep instead of dev-util/pkgconfig, all ebuilds in gentoo tree migrated.

Infinality has a new version out

Can someone enlighten me on the differences between the lcd-filtering overlay and MeisterP's infinality overlay? What would be reasons to choose one over the other?

Also, I'd like to see if it is feasible to get these patches into the official portage tree. Is anyone willing to work with me to maintain these?

The lcd-filtering overlay is patching media-libs/fontconfig and some fonts packages to apply the various infinality font settings. I (poncho aka MeisterP) made a media-libs/fontconfig-infinality package to install all configuration files into /etc/fonts/infinality/ and use an unpatched media-libs/fontconfig.

The reason for doing this was to follow infinality's rpm packages more closely and to have a live ebuild for https://github.com/Infinality/fontconfig-infinality.

If we want to have a fontconfig-infinality package in the tree, it would be worthwhile to replace the infctl tool (which manages symlinks in /etc/fonts/infinality/) with a proper eselect module.

If there are more questions concerning my overlay feel free to ask. And yes, I would be willing to (proxy?)maintain the packages with you.

There'll be one less patch file required in future

It's very good to see that he's working with the Freetype devs to get his patches in. Less work for us, indeed!

This sounds like a reasonable approach to get this into portage. I will look at it in more detail over the coming days (quite busy with work atm), and see if I can convince the freetype and cairo maintainers to work with us.

Hi,

Lcd-filtering overlay needs a update: there are freetype-2.4.10 in portage tree and the infinality patch.

http://www.infinality.net/forum/viewtopic.php?f=2&t=79

EDIT: also libXft-2.3.1

Thanks!!!

This is how it looks with default infinality freetype/fontconfig settings:

http://img440.imageshack.us/img440/1761/snimka2m.png

Note that there are also different freetype seetings like: (freetype-2.4.10)

Code: Select all

# Possible options: 
# 
# DEFAULT      - Use above settings.  A compromise that should please most people.
# OSX          - Simulate OSX rendering
# UBUNTU       - Simulate UBUNTU rendering
# LINUX        - Generic "Linux" style - no snapping or certain other tweaks
# WINDOWS      - Simulate Windows rendering
# WINDOWS7     - Simulate Windows rendering with normal glyphs
# WINDOWS7LIGHT- Simulate Windows 7 rendering with lighter glyphs
# WINDOWS      - Simulate Windows rendering
# VANILLA      - Just subpixel hinting
# CUSTOM       - Your own choice.  See below
# ----- Infinality styles -----
# CLASSIC      - Infinality rendering circa 2010.  No snapping.
# NUDGE        - CLASSIC with lightly stem snapping and tweaks
# PUSH         - CLASSIC with medium stem snapping and tweaks
# SHOVE        - Full stem snapping and tweaks without sharpening
# SHARPENED    - Full stem snapping, tweaks, and Windows-style sharpening
# INFINALITY   - Settings I use
# DISABLED     - Act as though running without the extra infinality enhancements (just subpixel hinting).

and fontconfig settings:

Code: Select all

acer infinality# ./infctl.sh setstyle
Select a style:
1) debug       3) linux       5) osx2        7) win98
2) infinality  4) osx         6) win7        8) winxp
