Python Imaging Library is afree and open-source additionallibrary for thePython programming language that adds support for opening,manipulating, and saving many differentimage file formats. It is available forWindows,Mac OS X andLinux. 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 asPIL, was discontinued in 2011.[2] Subsequently, a successor project namedPillowforked the PIL repository and added Python 3.x support.[5] This fork has been adopted as a replacement for the original PIL inLinux distributions includingDebian[6] andUbuntu (since13.04).[7]
PIL offers several standard procedures for image manipulation. These include:
Supported file formats includePPM,PNG,JPEG,GIF,TIFF, andBMP.PIL is extensible, allowing users to create custom decoders for any file format.[11]
