    <title>Image enhancements</title>
    <p>Select <gui>Smooth images when zoomed-out</gui> to enable <em>image 
    smoothing</em> when you zoom in and out. 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>
       <p><gui>As check pattern:</gui></p>
       <p>将图像任何透明部分显示为检查图案</p>
      </item>
      <item>
       <p><gui>As custom color:</gui></p>
       <p>Displays any transparent parts of the image in a solid color that 
       you specify by clicking on the color selector button.</p>
      </item>
      <item>
       <p><gui>As background:</gui></p>
       <p>Displays any transparent parts of the image in the 
       <gui>Background</gui> color, if <gui>As custom color</gui> under 
       <gui>Background</gui> is checked. Otherwise, the default background 
       color is used.</p>

<title>Slide show preferences</title>
<media type="image" src="figures/slideshow-prefs.png" style="floatend" width="300"/> 
<p>To customize 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>Check <gui>Loop sequence</gui> if you want the slideshow to repeat 
  continuously. If unchecked, the slideshow will start at the picture you 
  selected, and finish at the last picture in the folder.</p>
