Pillow
======
.. Note:: Pillow >= 2.0.0 supports Python versions: 2.6, 2.7, 3.2, 3.3; Pillow < 2.0.0 supports Python versions: 2.4, 2.5, 2.6, 2.7.
.. image:: https://travis-ci.org/python-imaging/Pillow.png
Pillow is the "friendly" PIL fork by Alex Clark and Contributors. PIL is the Python Imaging Library by Fredrik Lundh and Contributors.
Introduction
------------
The fork author's goal is to foster active development of PIL through:
- Continuous integration testing via Travis-CI
- Publicized development activity on GitHub
- Regular releases to the Python Packaging Index
- Solicitation for community contributions and involvement on Imaging-SIG
Why a fork?
-----------
PIL is not setuptools compatible. Please see http://mail.python.org/pipermail/image-sig/2010-August/006480.html for a more detailed explanation. Also, PIL's current bi-yearly (or greater) release schedule is too infrequent to accomodate the large number and frequency of issues reported.
What about image code bugs?
---------------------------
Please report any non-packaging related issues here first:
- https://bitbucket.org/effbot/pil-2009-raclette/issues
Then open a ticket here:
- https://github.com/python-imaging/Pillow/issues
and provide a link to the first ticket so we can track the issue(s) upstream.
.. Note:: Prior to Pillow 2.0.0, very few image code changes were made. Pillow 2.0.0 adds Python 3 support and includes many bug fixes from around the internet.
Documentation
-------------
The API documentation included with PIL has been converted (from HTML generated by pythondoc) to reStructured text (via pandoc) and is now `hosted by readthedocs.org <http://pillow.readthedocs.org>`_. This is a work in progress: in order to re-generate new API documentation, either `pythondoc <http://effbot.org/zone/pythondoc.htm>`_ will have to be run again or the pythondoc functionality must be converted to Sphinx.
Community
---------
Pillow needs you! Please help us maintain PIL via:
- GitHub Code (https://github.com/python-imaging/Pillow)
- Freenode Chat (irc://irc.freenode.net#pil)
- Image-SIG Discussion (http://mail.python.org/mailman/listinfo/image-sig)
Platform support
----------------
Current platform support for Pillow. Binary distributions are contributed for each release on a volunteer basis, but the source should compile and run everywhere platform support is listed. In general, we aim to support all current versions of Linux, OS X, and Windows.
.. Note:: Contributors please test on your platform, edit this document and send a pull request

Introduction
--------------------------------------------------------------------
The Python Imaging Library (PIL) adds image processing capabilities
to your Python environment. This library provides extensive file
format support, an efficient internal representation, and powerful
image processing capabilities.
This source kit has been built and tested with Python 2.0 and newer,
on Windows, Mac OS X, and major Unix platforms. Large parts of the
library also work on 1.5.2 and 1.6.
The main distribution site for this software is:
http://www.pythonware.com/products/pil/
That site also contains information about free and commercial support
options, PIL add-ons, answers to frequently asked questions, and more.
Development versions (alphas, betas) are available here:
http://effbot.org/downloads/
The PIL handbook is not included in this distribution; to get the
latest version, check:
http://www.pythonware.com/library/
http://effbot.org/books/imagingbook/ (drafts)
For installation and licensing details, see below.
--------------------------------------------------------------------

Build instructions (all platforms)
--------------------------------------------------------------------
For a list of changes in this release, see the CHANGES document.
0. If you're in a hurry, try this:
$ tar xvfz Imaging-1.1.7.tar.gz
$ cd Imaging-1.1.7
$ python setup.py install
If you prefer to know what you're doing, read on.
1. Prerequisites.
If you need any of the features described below, make sure you
have the necessary libraries before building PIL.
feature library
-----------------------------------------------------------------
JPEG support libjpeg (6a or 6b)
http://www.ijg.org
http://www.ijg.org/files/jpegsrc.v6b.tar.gz
ftp://ftp.uu.net/graphics/jpeg/
PNG support zlib (1.2.3 or later is recommended)
http://www.gzip.org/zlib/
OpenType/TrueType freetype2 (2.3.9 or later is recommended)
support
http://www.freetype.org
http://freetype.sourceforge.net
CMS support littleCMS (1.1.5 or later is recommended)
support
http://www.littlecms.com/
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:
sudo apt-get install libjpeg62-dev
sudo apt-get install zlib1g-dev
sudo apt-get install libfreetype6-dev
sudo apt-get install liblcms1-dev
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).
Similar tools are available for many other platforms.
2. To build under Python 1.5.2, you need to install the stand-alone
version of the distutils library:
http://www.python.org/sigs/distutils-sig/download.html
You can fetch distutils 1.0.2 from the Python source repository:
svn export http://svn.python.org/projects/python/tags/Distutils-1_0_2/Lib/distutils/
For newer releases, the distutils library is included in the
Python standard library.
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.
3. 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:
sudo apt-get install python-dev
4. When you have everything you need, unpack the PIL distribution
(the file Imaging-1.1.7.tar.gz) in a suitable work directory:
$ cd MyExtensions # example
$ gunzip Imaging-1.1.7.tar.gz
$ tar xvf Imaging-1.1.7.tar
5. Build the library. We recommend that you do an in-place build,
and run the self test before installing.
$ cd Imaging-1.1.7
$ python setup.py build_ext -i
$ python selftest.py
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:
----------------------------------------------------------------
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
----------------------------------------------------------------
Make sure that the optional components you need are included.
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.
If the build script finds the component, but the tests cannot
identify it, try rebuilding *all* modules:
$ python setup.py clean
$ python setup.py build_ext -i
6. If the setup.py and selftest.py commands finish without any
errors, you're ready to install the library:
$ python setup.py install
(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'.)
--------------------------------------------------------------------
Additional notes for Mac OS X
--------------------------------------------------------------------
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.
--------------------------------------------------------------------
Additional notes for Windows
--------------------------------------------------------------------
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.
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).
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:
http://www.microsoft.com/Express/
To build extensions using other tool chains, see the "Using
non-Microsoft compilers on Windows" section in the distutils handbook:
http://www.python.org/doc/current/inst/non-ms-compilers.html
For additional information on how to build extensions using the
popular MinGW compiler, see:
http://mingw.org (compiler)
http://sebsauvage.net/python/mingw.html (build instructions)
http://sourceforge.net/projects/gnuwin32 (prebuilt libraries)
