Chrome OS font rendering settings are specified using Fontconfig. If your
|
|
system's configuration doesn't match Chrome OS's (which vary for different
|
|
devices), fonts may be rendered with different subpixel rendering, subpixel
|
|
positioning, or hinting settings. This may affect font metrics.
|
|
|
|
Chrome OS's settings are stored in the media-libs/fontconfig package, which is
|
|
at src/third_party/chromiumos-overlay/media-libs/fontconfig in a Chrome OS
|
|
checkout. You can configure your system to match Chrome OS's defaults by
|
|
creating or editing a ~/.fonts.conf file:
|
|
|
|
<?xml version="1.0"?>
|
|
<!DOCTYPE fontconfig SYSTEM "fonts.dtd">
|
|
<fontconfig>
|
|
<match target="font">
|
|
<edit name="antialias" mode="assign"><bool>true</bool></edit>
|
|
<edit name="autohint" mode="assign"><bool>true</bool></edit>
|
|
<edit name="hinting" mode="assign"><bool>true</bool></edit>
|
|
<edit name="hintstyle" mode="assign"><const>hintslight</const></edit>
|
|
<edit name="rgba" mode="assign"><const>rgb</const></edit>
|
|
</match>
|
|
</fontconfig>
|
|
|
|
To load additional per-font configs (and assuming you have Chrome OS checked
|
|
out), add the following immediately before the "</fontconfig>" line:
|
|
|
|
<include ignore_missing="yes">/path/to/src/third_party/chromiumos-overlay/media-libs/fontconfig/files/local.conf</include>
