| 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> |
| <!-- |
| Disable sub-pixel anti-aliasing to work around font corruption issues |
| in the emulator. This disables it for your entire system. See |
| http://crbug.com/1442627 |
| --> |
| <edit name="rgba" mode="assign"><const>none</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> |
| """) |
