  <title>Engadir fondos de pantalla adicionais</title>

  <p>You can make extra backgrounds available to users on your system by
  following the steps below.</p>

  <steps>
  <title>Estabelecer fondos de pantalla adicionais</title>
  <item>
  <p>Create an XML file, for example <file><var>filename</var>.xml</file>.
  In this file, use keys from the <sys>org.gnome.desktop.background</sys>
  GSettings schema to specify extra backgrounds and their appearance.</p>

  <p>Below is a list of the most frequently used keys:</p>

  <table frame="top bottom" rules="all" shade="rows">
    <title>Chaves de esquemas de GSettings org.gnome.desktop.background</title>
    <tbody>
    <tr>
      <td><p>Nome da chave</p></td>
      <td><p>Valores posíbeis</p></td>
      <td><p>Descrición</p></td>
    </tr>
    <tr>
      <td><p>picture-options</p></td>
      <td><p>"none", "wallpaper", "centered", "scaled", "stretched", "zoom", "spanned"</p></td>
      <td><p>Determines how the image set by <var>wallpaper_filename</var> is rendered.</p></td>
    </tr>
    <tr>
      <td><p>color-shading-type</p></td>
      <td><p>«horizontal», «vertical» e «sólido»</p></td>
      <td><p>Como sombrear a cor de fondo.</p></td>
    </tr>
    <tr>
      <td><p>primary-color</p></td>
      <td><p>predeterminado: #023c88</p></td>
      <td><p>Cor esquerda ou superior ao deseñar gradientes ou a cor sólida.</p></td>
    </tr>
    <tr>
      <td><p>secondary-color</p></td>
      <td><p>predeterminado: #5789ca</p></td>
      <td><p>Cor dereita ou inferior ao deseñar gradientes, non usados para cor sólida.</p></td>
    </tr>
  </tbody>
  </table>

  <p>You can view a complete list of <sys>org.gnome.desktop.background</sys>
  keys and possible values using <app>dconf-editor</app> or the <cmd>gsettings</cmd>
  command-line utility. See <link xref="gsettings-browse"/> for more information.

  </item>
  <item>
  <p>Place the <file><var>filename</var>.xml</file> file in the
  <file>/usr/share/gnome-background-properties/</file> directory.</p>
  <p>Users will have the extra backgrounds available for configuration from
  <guiseq><gui>Settings</gui> <gui>Background</gui></guiseq>.</p>
  </item>
  </steps>


  <section id="backgrounds-extra-two-wallpapers">
  <title>Especificar varios fondos de pantalla</title>
  <p>In one configuration file, you can specify multiple
  <code>&lt;wallpaper&gt;</code> elements to add more backgrounds.</p>
  <p>See the following example with two <code>&lt;wallpaper&gt;</code> elements,
  adding two different backgrounds:</p>

<code mime="application/xml"><![CDATA[
