148258 - Xft sub-pixel support on X Mozilla for LCD monitors

Status: RESOLVED WORKSFORME

(Core :: Internationalization, defect)

Description

[Jeffrey Phillips]

This is related to bug http://bugzilla.mozilla.org/show_bug.cgi?id=126919 _Xft
support on X Mozilla_.  

Need to add an option for sub-pixel font rendering support that is a part of Xft
to improve LCD monitor and laptop browsing.

On X with Xft lib, the XftConfig file has the option:

    match edit rgba = [value];

Where [value] can be rgb, bgr, vrgb, or vbgr which determines the sub-pixel
colorization direction scheme.

This site http://grc.com/cleartype.htm is the best resource for learning about
the concepts.

You can have the same option in the new XML based format
its in /etc/fonts/fonts.conf for pre-1.0 builds
and in /usr/lib/mozilla-1.0.0/res/Xft/fonts.conf in the 1.0 build

<match target="font">
 <edit name="rgba" mode="assign">
   <const>rgb</const>
 </edit>
</match>

If this really is Xft this should be assigned to blizzard.

This seems to be fixed. With an Xft enabled build, and with the linex from
comment  2 in my ~/.fonts.config I have colored edges to my fonts. That seems
subpixal anti-alias to me. I don't hace an LCD screen.
