Python Pillow - Working with Images

In this article, we will see how to work with images using Pillow in Python. We will discuss basic operations like creating, saving, rotating images. So let's get started discussing in detail but first, let's see how to install pillow.

Installation

To install this package type the below command in the terminal.

pip install pillow

Creating new image

You can create a new image using PIL.Image.new() method. This method creates a new image with the given mode and size. Size is given as a (width, height)-tuple, in pixels

Syntax: PIL.Image.new(mode, size, color)

Code:

Output:

👁 Image

Opening image

You can open any image using PIL.Image.open() method.

Syntax: PIL.Image.open(fp, mode=’r’)

Code:

Output:

👁 Image

Getting Information about the image

• Getting the format of the image: obj.format method returns the format of the image file.

Output:

PNG

• Getting the size of the image: obj.size attribute provides the size of the image. It returns a tuple that contains width and height.

Output:

(180, 263)

Renaming and Saving Image

We can change the name, format of the image, and can also rename it using the image.save() method.

Syntax: Image.save(fp, format=None, **params)

Code:

Output:

👁 Image

👁 Image

Cropping the image

PIL is the Python Imaging Library which provides the python interpreter with image editing capabilities. PIL.Image.crop() method is used to crop a rectangular portion of any image.

Syntax: PIL.Image.crop(box = None)

Code:

Output:

👁 Image

👁 Image

Rotating the image

PIL.Image.Image.rotate() method is used to rotate a given image to the given number of degrees counterclockwise around its center.

Syntax: new_object = PIL.Image.Image.rotate(image_object, angle, resample=0, expand=0) OR new_object = image_object.rotate(angle, resample=0, expand=0)

Code:

Output:

👁 Image

👁 Image

Filtering the image

The current version of the Pillow library provides the below-mentioned set of predefined image enhancement filters.

• BLUR
• CONTOUR
• DETAIL
• EDGE_ENHANCE
• EDGE_ENHANCE_MORE
• EMBOSS
• FIND_EDGES
• SHARPEN
• SMOOTH
• SMOOTH_MORE

The ImageFilter module contains definitions for a pre-defined set of filters, which can be used with the Image.filter() method.

Syntax: Filter(Kernel) 

Takes in a kernel (predefined or custom) and each pixel of the image through it (Kernel Convolution). 

Code:

Output:

👁 Image

👁 Image

Creating a Watermark on the image

Here, you can create a watermark by using ImageDraw.Draw.text() This method draws the string at the given position.

Syntax: ImageDraw.Draw.text(xy, text, fill=None, font=None, anchor=None, spacing=0, align=”left”)

Code:

Output:

👁 Image

👁 Image
