Installing PIL


PIL, the Python imaging library, is a prerequisite for the image processing recipes in this chapter.

How to do it...

Let's see how to install PIL.

  • Installing PIL on Windows: Install using the Windows executable from the PIL website http://www.pythonware.com/products/pil/.

  • Installing on Debian or Ubuntu: On Debian or Ubuntu, install PIL using the following command:

    sudo apt-get install python-imaging
    
  • Installing with easy_install or pip: At the time of writing this book, it appeared that the package managers of Red Hat, Fedora, and CentOS did not have direct support for PIL. Therefore, please follow this step if you are using one of these Linux distributions.

    Install with either of the following commands:

    easy_install PIL
    sudo pip install PIL
