Улучшение рендеринга шрифтов

Как улучшить рендеринг с установленными шрифтами

A little configuration maybe required to render the fonts in an optimal manner. Follow the steps illustrated below.

1. Create the global fontconfig setting file /etc/fonts/local.conf

user $ sudo nano /etc/fonts/local.conf COPY TO CLIPBOARD

Paste the following content in the 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="hinting" mode="assign">
      <bool>true</bool>
    </edit>
    <edit mode="assign" name="rgba">
      <const>rgb</const>
    </edit>
    <edit mode="assign" name="hintstyle">
      <const>hintslight</const>
    </edit>
    <edit mode="assign" name="lcdfilter">
      <const>lcddefault</const>
    </edit>
  </match>
</fontconfig>

After that save the file.

2. Create backup of ~/.Xresources file:

user $ cp ~/.Xresources ~/.Xresources.bak COPY TO CLIPBOARD

If the .Xresources file has not been already created and you get the error

"cp: cannot stat ‘~/.Xresources’: No such file or directory", then skip to step No. 3.

3. Open/Create ~/.Xresources file in text editor:

user $ nano ~/.Xresources COPY TO CLIPBOARD

If the following is not already present, paste at the end of the file or edit existing values:

Xft.antialias: 1
Xft.hinting: 1
Xft.rgba: rgb
Xft.hintstyle: hintslight
Xft.lcdfilter: lcddefault

Save changes to the file.

4. Run the following command in terminal:

user $ xrdb -merge ~/.Xresources COPY TO CLIPBOARD

5. Make sure that Anti aliasing is On, Hinting is set to Slight and RGBA (subpixel) order is set to rgb in System Settings (Appearance).

6. Create symbolic links with some available presets from /usr/share/fontconfig/conf.avail/ to /etc/fonts/conf.d/

user $ sudo ln -s /usr/share/fontconfig/conf.avail/10-sub-pixel-rgb.conf /etc/fonts/conf.d/ COPY TO CLIPBOARD

user $ sudo ln -s /usr/share/fontconfig/conf.avail/10-hinting-slight.conf /etc/fonts/conf.d/ COPY TO CLIPBOARD

user $ sudo ln -s /usr/share/fontconfig/conf.avail/11-lcdfilter-default.conf /etc/fonts/conf.d/ COPY TO CLIPBOARD

7. Set preferred serif, sans-serif and monospace fonts (optional)

Create local fontconfig folder and setting file

user $ mkdir -p ~/.config/fontconfig/ COPY TO CLIPBOARD

user $ nano ~/.config/fontconfig/fonts.conf COPY TO CLIPBOARD

Paste the following content in the file

<?xml version="1.0"?>
<!DOCTYPE fontconfig SYSTEM "fonts.dtd">
<fontconfig>
  <alias>
    <family>serif</family>
    <prefer>
      <family>Liberation Serif</family>
    </prefer>
  </alias>
  <alias>
    <family>sans-serif</family>
    <prefer>
      <family>Liberation Sans</family>
    </prefer>
  </alias>
  <alias>
    <family>sans</family>
    <prefer>
      <family>Liberation Sans</family>
    </prefer>
  </alias>
  <alias>
    <family>monospace</family>
    <prefer>
      <family>Liberation Mono</family>
    </prefer>
  </alias>
  <alias>
    <family>mono</family>
    <prefer>
      <family>Liberation Mono</family>
    </prefer>
  </alias>
</fontconfig>

8. Finally enable freetype2 infinality mode and reboot your computer.

add line to end of freetype2 config file and then rebuild fontconfig cache

user $ sudo nano /etc/profile.d/freetype2.sh COPY TO CLIPBOARD

user $ export FREETYPE_PROPERTIES="truetype:interpreter-version=38" COPY TO CLIPBOARD

user $ sudo fc-cache -fv COPY TO CLIPBOARD
