Pillow 1.0

Python Imaging Library (fork)

Latest Version: 4.0.0

Pillow

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”.

Please email: aclark@aclark.net if you’d like to help, or complain.

(*)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.

For PIL’s README, check out PIL.txt

Build instructions (all platforms)

For a list of changes in this release, see the CHANGES document.

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.

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.

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.

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

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

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

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:
