Pillow ====== .. Note:: Pillow < 2.0.0 supports Python 2.4, 2.5, 2.6, 2.7; Pillow >= 2.0.0 supports Python 2.6, 2.7, 3.2, 3.3. .. Note:: Pillow >= 2.1.0 no longer supports "import _imaging". Please use "from PIL import Image.core as _imaging" instead. .. image:: https://travis-ci.org/python-imaging/Pillow.png :target: https://travis-ci.org/python-imaging/Pillow 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 <https://travis-ci.org/python-imaging/Pillow>`_ - Publicized development activity on `GitHub <https://github.com/python-imaging/Pillow>`_ - Regular releases to the `Python Package Index <https://pypi.python.org/pypi/Pillow>`_ - Solicitation for community contributions and involvement on `Image-SIG <http://mail.python.org/mailman/listinfo/image-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? ~~~~~~~~~~~~~~~~~~~~~~~~~~~ .. Note:: Prior to Pillow 2.0.0, very few image code changes were made. Pillow 2.0.0 added Python 3 support and includes many bug fixes from many contributors. 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. Installation ------------ .. Note:: PIL and Pillow currently cannot co-exist in the same environment. If you want to use Pillow, please remove PIL first. TL;DR: :: $ pip install Pillow For more information, please see http://python-imaging.github.io/ or below. 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 --------- PIL needs you! Please help us maintain the Python Imaging Library here: - GitHub (https://github.com/python-imaging/Pillow) - Freenode (irc://irc.freenode.net#pil) - Image-SIG (http://mail.python.org/mailman/listinfo/image-sig) Support ~~~~~~~ If you don't want to help with development, you can help us financially. Your donation will be very much appreciated. .. Note:: New contributors: please add your name (and donation preference) here and send a pull request. Pillow is a (labor of love) volunteer effort led by Alex Clark. Any contributor interested in receiving donations may add their name (and donation preference) here. +--------------------------------------+---------------------------------------+ | **Developer** | **Preference** | +--------------------------------------+---------------------------------------+ | Alex Clark (fork author) | http://gittip.com/aclark4life | +--------------------------------------+---------------------------------------+ Developer --------- 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:: If there is a binary package for your system, that is the easiest way to install Pillow. But we currently only provide binaries for Windows (via Python eggs). ..

[1] x86 only .. [2] In some cases, x86 support may indicate 32-bit compilation on 64-bit architecture (vs. compilation on 32-bit hardware). Build from source ~~~~~~~~~~~~~~~~~ Some (most?) of Pillow's features require external libraries. * **libjpeg** provides JPEG functionality. * Pillow has been tested with libjpeg versions **6b**, **8**, and **9** * **zlib** provides access to compressed PNGs * **libtiff** provides group4 tiff functionality * Pillow has been tested with libtiff versions **3.x** and **4.0** * **libfreetype** provides type related services * **littlecms** provides color management * **libwebp** provides the Webp format. * Pillow has been tested with version **0.1.3**, which does not read transparent webp files. Version **0.3.0** supports transparency. If the prerequisites are installed in the standard library locations for your machine (e.g. /usr or /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 (i.e. by editing setup.py and/or setup.cfg). Once you have installed the prerequisites, run:: $ pip install Pillow Platform-specific instructions ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Linux +++++ **We don't currently 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 Prerequisites are installed on **Ubuntu 10.04 LTS** with:: $ sudo apt-get install libtiff4-dev libjpeg62-dev zlib1g-dev libfreetype6-dev liblcms1-dev Prerequisites are installed with on **Ubuntu 12.04 LTS** with :: $ sudo apt-get install libtiff4-dev libjpeg8-dev zlib1g-dev libfreetype6-dev liblcms1-dev libwebp-dev Mac OS X ++++++++ **We don't currently provide binaries for OS X.** So you'll need XCode to install Pillow. (XCode 4.2 on 10.6 will work with the Official Python binary distribution. Otherwise, use whatever XCode you used to compile Python.) The easiest way to install the prerequisites is via `Homebrew <http://mxcl.github.com/homebrew/>`_. After you install Homebrew, run:: $ brew install libtiff libjpeg webp littlecms If you've built your own Python, then you should be able to install Pillow using:: $ pip install Pillow Windows +++++++ .. Note:: If Windows eggs have been released to PyPI, the following should work. :: $ easy_install Pillow Port existing PIL-based code to Pillow ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Pillow is a functional drop-in replacement for the Python Imaging Library. To run your existing PIL-compatible code with Pillow, it needs to be modified to import the ``Imaging`` module from the ``PIL`` namespace *instead* of the global namespace. I.e. change:: import Image to:: from PIL import Image .. Note:: If your code imports from ``_imaging``, it will no longer work. The preferred, future proof method of importing the private ``_imaging`` module is:: from PIL import Image _imaging = Image.core Python Imaging Library ====================== .. Note:: What follows is the original PIL 1.1.7 README file contents. :: The Python Imaging Library $Id$ Release 1.1.7 (November 15, 2009) ==================================================================== The Python Imaging Library 1.1.7 ==================================================================== Contents -------- + Introduction + Support Options - Commercial support - Free support + Software License + Build instructions (all platforms) - Additional notes for Mac OS X - Additional notes for Windows -------------------------------------------------------------------- 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. -------------------------------------------------------------------- Support Options -------------------------------------------------------------------- + Commercial Support Secret Labs (PythonWare) offers support contracts for companies using the Python Imaging Library in commercial applications, and in mission- critical environments. The support contract includes technical support, bug fixes, extensions to the PIL library, sample applications, and more.

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)
