Extra achtergronden toevoegen

U kunt extra achtergronden ter beschikking stellen van de gebruikers van uw systeem door de stappen hieronder te volgen.

Extra achtergronden instellen

  1. Maak een XML-bestand aan, bijvoorbeeld bestandsnaam.xml. Gebruik in dit bestand sleutels van het GSettings-schema org.gnome.desktop.background om extra achtergronden en hun uiterlijk in te stellen.

    Hieronder vindt u een lijst van de meestgebruikte sleutels:

    org.gnome.desktop.background schemas GSettings keys

    Sleutelnaam

    Mogelijke waarden

    Beschrijving

    picture-options

    "none", "wallpaper", "centered", "scaled", "stretched", "zoom", "spanned"

    Determines how the image set by wallpaper_filename is rendered.

    color-shading-type

    "horizontal", "vertical", and "solid"

    How to shade the background color.

    primary-color

    default: #023c88

    Left or top color when drawing gradients, or the solid color.

    secondary-color

    default: #5789ca

    Right or bottom color when drawing gradients, not used for solid color.

    You can view a complete list of org.gnome.desktop.background keys and possible values using dconf-editor or the gsettings command-line utility. See Browse GSettings values for your applications for more information.

    Below is a sample filename.xml file:

    <?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE wallpapers SYSTEM "gnome-wp-list.dtd">
<wallpapers>
  <wallpaper deleted="false">
    <name>Company Background</name>
    <name xml:lang="de">Firmenhintergrund</name>
    <filename>/usr/local/share/backgrounds/company-wallpaper.jpg</filename>
    <options>zoom</options>
    <shade_type>solid</shade_type>
    <pcolor>#ffffff</pcolor>
    <scolor>#000000</scolor>
  </wallpaper>
</wallpapers>

  2. Place the filename.xml file in the /usr/share/gnome-background-properties/ directory.

    Users will have the extra backgrounds available for configuration from Settings ▸ Background.

Meerdere achtergronden instellen

In one configuration file, you can specify multiple <wallpaper> elements to add more backgrounds.

See the following example with two <wallpaper> elements, adding two different backgrounds:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE wallpapers SYSTEM "gnome-wp-list.dtd">
<wallpapers>
  <wallpaper deleted="false">
    <name>Company Background</name>
    <name xml:lang="de">Firmenhintergrund</name>
    <filename>/usr/local/share/backgrounds/company-wallpaper.jpg</filename>
    <options>zoom</options>
    <shade_type>solid</shade_type>
    <pcolor>#ffffff</pcolor>
    <scolor>#000000</scolor>
  </wallpaper>
  <wallpaper deleted="false">
    <name>Company Background 2</name>
    <name xml:lang="de">Firmenhintergrund 2</name>
    <filename>/usr/local/share/backgrounds/company-wallpaper-2.jpg</filename>
    <options>zoom</options>
    <shade_type>solid</shade_type>
    <pcolor>#ff0000</pcolor>
    <scolor>#00ffff</scolor>
  </wallpaper>
</wallpapers>
