Python Imaging Library (abbreviated as PIL) (in newer versions known as Pillow) 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".
Development appears to be discontinued with the last commit to the PIL repository coming in 2011. Consequently, a successor project called Pillow has forked the PIL repository and added Python 3.x support. This fork has been adopted as a replacement for the original PIL in Linux distributions including Debian and Ubuntu (since 13.04).
Pillow 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.
This example loads an image from the hard drive and blurs it.
from PIL import Image, ImageFilter # imports the library original = Image.open("file.ppm") # load an image from the hard drive blurred = original.filter(ImageFilter.BLUR) # blur the image original.show() # display both images blurred.show()
