<h1>Pillow</h1>
|
||
|
|
<p>Pillow is a "friendly" fork of the Python Imaging Library. The goal is to see
|
||
|
|
if any improvement can be made to the packaging situation(*) by opening up
|
||
|
|
development to the "public".</p>
|
||
|
|
<p>Please email: <a class="reference external" href="mailto:aclark@aclark.net">aclark@aclark.net</a> if you'd like to help, or complain.</p>
|
||
|
|
<p>(*)PIL has a bad reputation for not "playing nice" with other packages. It's
|
||
|
|
kind of a long story, and you either know it by now or you don't. A better
|
||
|
|
explanation may come later.</p>

|
||
|
|
<p>If you have a recent Linux version, the libraries provided with the
|
||
|
|
operating system usually work just fine. If some library is
|
||
|
|
missing, installing a prebuilt version (jpeg-devel, zlib-devel,
|
||
|
|
etc) is usually easier than building from source. For example, for
|
||
|
|
Ubuntu 9.10 (karmic), you can install the following libraries:</p>
|
||
|
|
<pre class="literal-block">
|
||
|
|
sudo apt-get install libjpeg62-dev
|
||
|
|
sudo apt-get install zlib1g-dev
|
||
|
|
sudo apt-get install libfreetype6-dev
|
||
|
|
sudo apt-get install liblcms1-dev
|
||
|
|
</pre>
|
||
|
|
<p>If you're using Mac OS X, you can use the 'fink' tool to install
|
||
|
|
missing libraries (also see the Mac OS X section below).</p>
|
||
|
|
<p>Similar tools are available for many other platforms.</p>
|
||
|
|
<p>To build under Python 1.5.2, you need to install the stand-alone
|
||
|
|
version of the distutils library:</p>
|
||
|
|
<blockquote>
|
||
|
|
<a class="reference external" href="http://www.python.org/sigs/distutils-sig/download.html">http://www.python.org/sigs/distutils-sig/download.html</a></blockquote>
|
||
|
|
<p>You can fetch distutils 1.0.2 from the Python source repository:</p>
|
||
|
|
<blockquote>
|
||
|
|
svn export <a class="reference external" href="http://svn.python.org/projects/python/tags/Distutils-1_0_2/Lib/distutils/">http://svn.python.org/projects/python/tags/Distutils-1_0_2/Lib/distutils/</a></blockquote>
|
||
|
|
<p>For newer releases, the distutils library is included in the
|
||
|
|
Python standard library.</p>
|
||
|
|
<p>NOTE: Version 1.1.7 is not fully compatible with 1.5.2. Some
|
||
|
|
more recent additions to the library may not work, but the core
|
||
|
|
functionality is available.</p>
|
||
|
|
<p>If you didn't build Python from sources, make sure you have
|
||
|
|
Python's build support files on your machine. If you've down-
|
||
|
|
loaded a prebuilt package (e.g. a Linux RPM), you probably
|
||
|
|
need additional developer packages. Look for packages named
|
||
|
|
"python-dev", "python-devel", or similar. For example, for
|
||
|
|
Ubuntu 9.10 (karmic), use the following command:</p>
|
||
|
|
<blockquote>
|
||
|
|
sudo apt-get install python-dev</blockquote>
|
||
|
|
<p>When you have everything you need, unpack the PIL distribution
|
||
|
|
(the file Imaging-1.1.7.tar.gz) in a suitable work directory:</p>
|
||
|
|
<blockquote>
|
||
|
|
$ cd MyExtensions # example
|
||
|
|
$ gunzip Imaging-1.1.7.tar.gz
|
||
|
|
$ tar xvf Imaging-1.1.7.tar</blockquote>
|
||
|
|
<p>Build the library. We recommend that you do an in-place build,
|
||
|
|
and run the self test before installing.</p>
|
||
|
|
<blockquote>
|
||
|
|
$ cd Imaging-1.1.7
|
||
|
|
$ python setup.py build_ext -i
|
||
|
|
$ python selftest.py</blockquote>
|
||
|
|
<p>During the build process, the setup.py will display a summary
|
||
|
|
report that lists what external components it found. The self-
|
||
|
|
test will display a similar report, with what external components
|
||
|
|
the tests found in the actual build files:</p>

PIL 1.1.7 SETUP SUMMARY
|
||
|
|
----------------------------------------------------------------
|
||
|
|
*** TKINTER support not available (Tcl/Tk 8.5 libraries needed)
|
||
|
|
--- JPEG support available
|
||
|
|
--- ZLIB (PNG/ZIP) support available
|
||
|
|
--- FREETYPE support available
|
||
|
|
----------------------------------------------------------------
|
||
|
|
</pre>
|
||
|
|
<p>Make sure that the optional components you need are included.</p>
|
||
|
|
<p>If the build script won't find a given component, you can edit the
|
||
|
|
setup.py file and set the appropriate ROOT variable. For details,
|
||
|
|
see instructions in the file.</p>
|
||
|
|
<p>If the build script finds the component, but the tests cannot
|
||
|
|
identify it, try rebuilding <em>all</em> modules:</p>
|
||
|
|
<blockquote>
|
||
|
|
$ python setup.py clean
|
||
|
|
$ python setup.py build_ext -i</blockquote>
|
||
|
|
<p>If the setup.py and selftest.py commands finish without any
|
||
|
|
errors, you're ready to install the library:</p>
|
||
|
|
<blockquote>
|
||
|
|
$ python setup.py install</blockquote>
|
||
|
|
<p>(depending on how Python has been installed on your machine,
|
||
|
|
you might have to log in as a superuser to run the 'install'
|
||
|
|
command, or use the 'sudo' command to run 'install'.)</p>

<h3>Additional notes for Mac OS X</h3>
|
||
|
|
<p>On Mac OS X you will usually install additional software such as
|
||
|
|
libjpeg or freetype with the "fink" tool, and then it ends up in
|
||
|
|
"/sw". If you have installed the libraries elsewhere, you may have
|
||
|
|
to tweak the "setup.py" file before building.</p>

<div class="section" id="additional-notes-for-windows">

|
|
<h3>Additional notes for Windows</h3>
|
||
|
|
<p>On Windows, you need to tweak the ROOT settings in the "setup.py"
|
||
|
|
file, to make it find the external libraries. See comments in the
|
||
|
|
file for details.</p>
|
||
|
|
<p>Make sure to build PIL and the external libraries with the same
|
||
|
|
runtime linking options as was used for the Python interpreter
|
||
|
|
(usually /MD, under Visual Studio).</p>
|
||
|
|
<p>Note that most Python distributions for Windows include libraries
|
||
|
|
compiled for Microsoft Visual Studio. You can get the free Express
|
||
|
|
edition of Visual Studio from:</p>
