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.^[3]

Development of the original project, known as PIL, was discontinued in 2011.^[2] Subsequently, a successor project named Pillow forked the PIL repository and added Python 3.x support.^[5] This fork has been adopted as a replacement for the original PIL in Linux distributions including Debian ^[6] and Ubuntu (since 13.04).^[7]

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

• per-pixel manipulations,^[8]
• masking and transparency handling,
• image filtering, such as blurring, contouring, smoothing, or edge finding,^[9]
• image enhancing, such as sharpening, adjusting brightness, contrast or color,^[10]
• adding text

Supported file formats include PPM, PNG, JPEG, GIF, TIFF, and BMP. PIL is extensible, allowing users to create custom decoders for any file format.^[11]
