    <title>Image enhancements</title>
    <p>Select <gui>Smooth images when zoomed out</gui> and/or <gui>Smooth images when zoomed in</gui> to enable <em>image smoothing</em>. This makes low-resolution (pixelated) pictures look better by smoothing out jagged edges.</p>
    <p>If you enable <gui>Automatic orientation</gui>, pictures will be automatically rotated according to their <em>Exif metadata</em>. This is information about a picture that is automatically inserted by a digital camera, and can include details on which way up the camera was held when the picture was taken. For example, when automatic orientation is enabled, portrait photos are automatically rotated upright. The rotation is not saved until you <link xref="flip-rotate#rotate">save the rotated image</link>.</p> 
    <p>Automatic orientation does not work with all pictures; only pictures taken using a camera that saves Exif orientation metadata will be rotated.</p>
  </item>
  <item>
    <title>Background</title>
    <p>Here you can select a custom background colour.</p>

      <item>
       <p><gui>As check pattern:</gui></p>
       <p>Displays any transparent parts of the image in a check pattern.</p>
      </item>
      <item>
       <p><gui>As custom colour:</gui></p>
       <p>Displays any transparent parts of the image in a solid colour that you specify by clicking on the colour selector button.</p>
      </item>
      <item>
       <p><gui>As background:</gui></p>
       <p>Displays any transparent parts of the image in the <gui>Background</gui> colour, if <gui>As custom colour</gui> under <gui>Background</gui> is ticked. Otherwise, the default background colour is used.</p>

<p>To customise slideshow settings:</p>
<list>
 <item>
  <p>Under <gui>Image Zoom</gui> you can select if you would like pictures that are smaller than the screen to be expanded so that they fit the screen.</p>
 </item>
 <item>
  <p>Under <gui>Sequence</gui> you can select how many seconds each picture should be displayed for (between 1 and 100) before the next picture is shown.</p>
 </item>
 <item>
  <p>Tick <gui>Loop sequence</gui> if you want the slideshow to repeat continuously. If unticked, the slideshow will start at the picture you selected, and finish at the last picture in the folder.</p>
