PIL provides us with many functions to manipulate an image; for example, using a point transformation to change pixel values or to perform geometric transformations on an image. Let us first start by loading the parrot PNG image, as shown in the following code:

im = Image.open("../images/parrot.png")        # open the image, provide the correct path
print(im.width, im.height, im.mode, im.format) # print image size, mode and format
# 486 362 RGB PNG

The next few sections describe how to do different types of image manipulations with PIL.
