<h3>3D color lookup tables<a class="headerlink" href="#d-color-lookup-tables" title="Permalink to this headline">¶</a></h3>
<p>Support for 3D color lookup table transformations has been added.</p>
<ul class="simple">
<li><a class="reference external" href="https://en.wikipedia.org/wiki/3D_lookup_table">https://en.wikipedia.org/wiki/3D_lookup_table</a></li>
</ul>
<p><code class="docutils literal notranslate"><span class="pre">Color3DLUT.generate</span></code> transforms 3-channel pixels using the values of the
channels as coordinates in the 3D lookup table and interpolating the nearest
elements.</p>
<p>It allows you to apply almost any color transformation in constant time by
using pre-calculated decimated tables.</p>
<p><code class="docutils literal notranslate"><span class="pre">Color3DLUT.transform()</span></code> allows altering table values with a callback.</p>
<p>If NumPy is installed, the performance of argument conversion is dramatically
improved when a source table supports buffer interface (NumPy && arrays in
Python >= 3).</p>

<h3>ImageColor.getrgb<a class="headerlink" href="#imagecolor-getrgb" title="Permalink to this headline">¶</a></h3>
<p>Previously <code class="docutils literal notranslate"><span class="pre">Image.rotate</span></code> only supported HSL color strings. Now HSB and HSV

image file, where available. For example,
<code class="docutils literal notranslate"><span class="pre">Image.open("hopper.jpg").get_format_mimetype()</span></code> returns <code class="docutils literal notranslate"><span class="pre">"image/jpeg"</span></code>.</p>

<p>A new named parameter, <code class="docutils literal notranslate"><span class="pre">fillcolor</span></code>, has been added to <code class="docutils literal notranslate"><span class="pre">Image.rotate</span></code>. This
color specifies the background color to use in the area outside the rotated

<p>The macOS wheels for Pillow 5.1.0 were built with Xcode 9.2, meaning 10.12
Sierra was the lowest supported version.</p>
<p>Prior to Pillow 5.1.0, Xcode 8 was used, supporting El Capitan 10.11.</p>
<p>Instead, Pillow 5.2.0 is built with the oldest available Xcode 6.4 to support
at least 10.10 Yosemite.</p>

<h3>Resolve confusion getting PIL / Pillow version string<a class="headerlink" href="#resolve-confusion-getting-pil-pillow-version-string" title="Permalink to this headline">¶</a></h3>
<p>Re: “version constants deprecated” listed above, as user gnbl notes in #3082:</p>
<ul class="simple">
<li>it’s confusing that PIL.VERSION returns the version string of the former PIL instead of Pillow’s</li>
<li>there does not seem to be documentation on this version number (why this, will it ever change, ..) e.g. at <a class="reference external" href="https://pillow.readthedocs.io/en/5.1.x/about.html#why-a-fork">https://pillow.readthedocs.io/en/5.1.x/about.html#why-a-fork</a></li>
<li>it’s confusing that PIL.version is a module and does not return the version information directly or hints on how to get it</li>
<li>the package information header is essentially useless (placeholder, does not even mention Pillow, nor the version)</li>
<li>PIL._version module documentation comment could explain how to access the version information</li>
</ul>
<p>We have attempted to resolve these issues in #3083, #3090 and #3218.</p>
