Installation
============

Warnings
--------

.. warning:: Pillow and PIL cannot co-exist in the same environment. Before installing Pillow, please uninstall PIL.

.. warning:: Pillow >= 1.0 no longer supports "import Image". Please use "from PIL import Image" instead.

.. warning:: Pillow >= 2.1.0 no longer supports "import _imaging". Please use "from PIL.Image import core as _imaging" instead.

Notes
-----

.. note:: Pillow < 2.0.0 supports Python versions 2.4, 2.5, 2.6, 2.7.

.. note:: Pillow >= 2.0.0 supports Python versions 2.6, 2.7, 3.2, 3.3, 3.4, 3.5

Basic Installation
------------------

.. note::

    The following instructions will install Pillow with support for most common image formats. See :ref:`external-libraries` for a full list of external libraries supported.

Install Pillow with :command:`pip`::

    $ pip install Pillow

Or use :command:`easy_install` for installing `Python Eggs <http://peak.telecommunity.com/DevCenter/PythonEggs>`_ as :command:`pip` does not support them::

    $ easy_install Pillow

Or download and extract the `compressed archive from PyPI`_ and inside it run::

    $ python setup.py install

.. _compressed archive from PyPI: https://pypi.python.org/pypi/Pillow

External Libraries
------------------

.. note::

    You **do not need to install all external libraries supported** to use Pillow's basic features.

Many of Pillow's features require external libraries:

* **libjpeg** provides JPEG functionality.

  * Pillow has been tested with libjpeg versions **6b**, **8**, and
    **9** and libjpeg-turbo version **8**.
  * Starting with Pillow 3.0.0, libjpeg is required by default, but
    may be disabled with the ``--disable-jpeg`` flag.

* **zlib** provides access to compressed PNGs

  * Starting with Pillow 3.0.0, zlib is required by default, but may
    be disabled with the ``--disable-zlib`` flag.

* **libtiff** provides compressed TIFF functionality

  * Pillow has been tested with libtiff versions **3.x** and **4.0**

* **libfreetype** provides type related services

* **littlecms** provides color management

  * Pillow version 2.2.1 and below uses liblcms1, Pillow 2.3.0 and
    above uses liblcms2. Tested with **1.19** and **2.2**.

* **libwebp** provides the WebP format.

  * Pillow has been tested with version **0.1.3**, which does not read
    transparent WebP files. Versions **0.3.0** and **0.4.0** support
    transparency.

* **tcl/tk** provides support for tkinter bitmap and photo images.

* **openjpeg** provides JPEG 2000 functionality.

  * Pillow has been tested with openjpeg **2.0.0** and **2.1.0**.
  * Pillow does **not** support the earlier **1.5** series which ships
    with Ubuntu and Debian.

Once you have installed the prerequisites,run::

    $ pip install Pillow

If the prerequisites are installed in the standard library locations
for your machine (e.g. :file:`/usr` or :file:`/usr/local`), no
additional configuration should be required. If they are installed in
a non-standard location, you may need to configure setuptools to use
those locations by editing :file:`setup.py` or
:file:`setup.cfg`, or by adding environment variables on the command
line::

    $ CFLAGS="-I/usr/pkg/include" pip install pillow

Build Options
-------------

* Environment Variable: ``MAX_CONCURRENCY=n``. By default, Pillow will
  use multiprocessing to build the extension on all available CPUs,
  but not more than 4. Setting ``MAX_CONCURRENCY`` to 1 will disable
  parallel building.

* Build flags: ``--disable-zlib``, ``--disable-jpeg``,
  ``--disable-tiff``, ``--disable-freetype``, ``--disable-tcl``,
  ``--disable-tk``, ``--disable-lcms``, ``--disable-webp``,
  ``--disable-webpmux``, ``--disable-jpeg2000``. Disable building the
  corresponding feature even if the development libraries are present
  on the building machine.

* Build flags: ``--enable-zlib``, ``--enable-jpeg``,
  ``--enable-tiff``, ``--enable-freetype``, ``--enable-tcl``,
  ``--enable-tk``, ``--enable-lcms``, ``--enable-webp``,
  ``--enable-webpmux``, ``--enable-jpeg2000``. Require that the
  corresponding feature is built. The build will raise an exception if
  the libraries are not found. Webpmux (WebP metadata) relies on WebP
  support. Tcl and Tk also must be used together.

Sample Usage::

    $ MAX_CONCURRENCY=1 python setup.py build_ext --enable-[feature] install

OS X Installation
-----------------

We provide binaries for OS X in the form of `Python Wheels <http://wheel.readthedocs.org/en/latest/index.html>`_. Alternatively you can compile Pillow from source with XCode.

The easiest way to install external libraries is via `Homebrew <http://brew.sh/>`_. After you install Homebrew, run::

    $ brew install libtiff libjpeg webp little-cms2

Install Pillow with::

    $ pip install Pillow

Windows Installation
--------------------

We provide binaries for Windows in the form of Python Eggs and `Python Wheels
<http://wheel.readthedocs.org/en/latest/index.html>`_:

Python Eggs
^^^^^^^^^^^

.. note::

    :command:`pip` does not support Python Eggs; use :command:`easy_install`
    instead.

::

    $ easy_install Pillow

Python Wheels
^^^^^^^^^^^^^

.. Note:: Requires setuptools >=0.8 and pip >=1.4.1. Some older versions of pip required the ``--use-wheel`` flag.

::

    $ pip install Pillow

If the above does not work, it's likely because we haven't uploaded a
wheel for the latest version of Pillow. In that case, try pinning it
to a specific version:

::

    $ pip install Pillow==2.6.1

FreeBSD Installation
--------------------

.. Note:: Only FreeBSD 10 tested

Make sure you have Python's development libraries installed.::

    $ sudo pkg install python2

Or for Python 3::

    $ sudo pkg install python3

Prerequisites are installed on **FreeBSD 10** with::

    $ sudo pkg install jpeg tiff webp lcms2 freetype2

Linux Installation
------------------

.. note::

    Most major Linux distributions, including Fedora, Debian/Ubuntu
    and ArchLinux include Pillow in packages that previously contained
    PIL e.g. ``python-imaging``. Please consider using native
    operating system packages first to avoid installation problems
    and/or missing library support later.

**We do not provide binaries for Linux.** If you didn't build Python from
source, make sure you have Python's development libraries installed. In Debian
or Ubuntu::

    $ sudo apt-get install python-dev python-setuptools

Or for Python 3::

    $ sudo apt-get install python3-dev python3-setuptools

In Fedora, the command is::

    $ sudo yum install python-devel

Prerequisites are installed on **Ubuntu 12.04 LTS** or **Raspian Wheezy
7.0** with::

    $ sudo apt-get install libtiff4-dev libjpeg8-dev zlib1g-dev \
        libfreetype6-dev liblcms2-dev libwebp-dev tcl8.5-dev tk8.5-dev python-tk

Prerequisites are installed on **Ubuntu 14.04 LTS** with::

    $ sudo apt-get install libtiff5-dev libjpeg8-dev zlib1g-dev \
        libfreetype6-dev liblcms2-dev libwebp-dev tcl8.6-dev tk8.6-dev python-tk

Prerequisites are installed on **Fedora 20** with::

    $ sudo yum install libtiff-devel libjpeg-devel libzip-devel freetype-devel \
        lcms2-devel libwebp-devel tcl-devel tk-devel





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 Pillow on your platform then update this document and send a pull request.

Old Versions
------------

You can download old distributions from `PyPI
<https://pypi.python.org/pypi/Pillow>`_. Only the latest major
releases for Python 2.x and 3.x are visible, but all releases are
available by direct URL access
e.g. https://pypi.python.org/pypi/Pillow/1.0.
