<title>Zoom</title>

<p>You can zoom in and out to show more or less of a picture on the screen at once. This is useful if you want to see a big picture in its entirety, or if you want to inspect the fine details of a picture.</p>

<list>
 <item>
  <p>You can zoom using the mouse wheel. Scroll up to zoom in or scroll down to zoom out.</p>
 </item>
 <item>
  <p>You can also zoom using the buttons in the header bar. To zoom in, click the 
  <gui>Enlarge the image</gui> icon, and to zoom out click the <gui>Shrink the 
  image</gui> icon. These look like "plus" and "minus" signs.</p>
 </item>
 <item>
 <p>Alternatively, use the keyboard shortcuts <keyseq><key>Ctrl</key><key>+</key></keyseq> or
 <keyseq><key>Ctrl</key><key>-</key></keyseq>.</p>
 </item>
</list>

<p>To view the picture in its original, unscaled size, choose the
<gui style="menuitem">100%</gui> zoom level from the dropdown in the header bar.
Alternatively, use the keyboard shortcuts <keyseq><key>Ctrl</key><key>0</key></keyseq> or
<key>1</key>.</p>

<section id="bestfit">
 <title>Zoom to best-fit the window</title>
 <p>You can choose to zoom in so that the picture fits fully in the window, 
 even if you resize it. Enable <gui style="menuitem">Best fit</gui> 
 in the dropdown in the header bar to do this.</p>
