<p>Pillow is a functional drop-in replacement for the Python Imaging Library. To
run your existing PIL-compatible code with Pillow, it needs to be modified to
import the <tt class="docutils literal"><span class="pre">Image</span></tt> module from the <tt class="docutils literal"><span class="pre">PIL</span></tt> namespace <em>instead</em> of the
global namespace. Change this:</p>
<div class="highlight-python"><div class="highlight"><pre><span class="kn">import</span> <span class="nn">Image</span>
</pre></div>
</div>
<p>to this:</p>
<div class="highlight-python"><div class="highlight"><pre><span class="kn">from</span> <span class="nn">PIL</span> <span class="kn">import</span> <span class="n">Image</span>
</pre></div>
</div>
<p>The <tt class="xref py py-mod docutils literal"><span class="pre">_imaging</span></tt> module has been moved. You can now import it like this:</p>
<div class="highlight-python"><div class="highlight"><pre><span class="kn">from</span> <span class="nn">PIL.Image</span> <span class="kn">import</span> <span class="n">core</span> <span class="k">as</span> <span class="n">_imaging</span>
</pre></div>
</div>
<p>The image plugin loading mechanism has changed. Pillow no longer
automatically imports any file in the Python path with a name ending
in <tt class="file docutils literal"><span class="pre">ImagePlugin.py</span></tt>. You will need to import your image plugin
manually.</p>
