<p>The <a class="reference internal" href="#module-PIL.Image" title="PIL.Image"><tt class="xref py py-mod docutils literal"><span class="pre">Image</span></tt></a> module provides a class with the same name which is
used to represent a PIL image. The module also provides a number of factory
functions, including functions to load images from files, and to create new
images.</p>
