Python Imaging Library (abbreviated as PIL) is a free 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, with Python 3 support to be released "later".[2]
Development appears to be discontinued with the last commit to the PIL repository coming in 2011.[3] Consequently, a successor project called Pillow has 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 to images and much more.
File formats
Some of the file formats supported include PPM, PNG, JPEG, GIF, TIFF, and BMP. It is also possible to create new file decoders to expand the library of file formats accessible.[7]
Usage example
This example loads an image from the hard drive and blurs it.
from PIL import Image, ImageFilter original = Image.open("lena.ppm") # load an image from the hard drive blurred = original.filter(ImageFilter.BLUR) # blur the image original.show() # display both images blurred.show()
