Introduction to PIL
Image processing is a very widely used technology, and Python, which has a very rich third-party extension library, will certainly not miss this feast. PIL (Python Imaging Library) is the most commonly used image processing library in Python, the current version is 1.1.7, refer to the official information http://effbot.org/imagingbook/
The Image class is a very important class in the PIL library. To create an instance through this class, you can directly load the image file, read the processed image, and obtain the image through the grab method.
Note that PIL is not compatible with pillow.
