Python Imaging Library

Python Imaging Library is a free and open-source additional library for the Python programming language that adds support for opening, manipulating, and saving many different image file formats. It is available for Windows, Mac OS X and Linux. The latest version of PIL is 1.1.7, was released in September 2009 and supports Python 1.5.2–2.7.[2]

Development of the original project, known as PIL, was discontinued in 2011.[3] Subsequently, a successor project named Pillow forked the PIL repository and added Python 3.x support.[4] This fork has been adopted as a replacement for the original PIL in Linux distributions including Debian[5] and Ubuntu (since 13.04).[6]

Capabilities

PIL offers several standard procedures for image manipulation. These include:

  • per-pixel manipulations,
  • masking and transparency handling,
  • image filtering, such as blurring, contouring, smoothing, or edge finding,
  • image enhancing, such as sharpening, adjusting brightness, contrast or color,
  • adding text

File formats

Supported file formats include PPM, PNG, JPEG, GIF, TIFF, and BMP. PIL is extensible, allowing users to create custom decoders for any file format.[7]
