Prerequisite:

Python offers multiple options for developing GUI (Graphical User Interface). Out of all the GUI methods, Tkinter is the most commonly used method. It is a standard Python interface to the Tk GUI toolkit shipped with Python. Python with Tkinter is the fastest and easiest way to create GUI applications. Creating a GUI using Tkinter is an easy task.

In this article, we will learn how to resize an image using python in Tkinter. In Tkinter, there is no in-built method or any package to work with images. Here we will use pillow library for images.

Let’s Understand step by step implementation:-

  • Import Required Library

Python3




# Import Module
from tkinter import *
from PIL import Image, ImageTk

  • Read the image using the open() method in pillow library

Syntax: 

Image.open("Enter Image File Path", mode='r', **attr)

Python3




# Read the Image
image = Image.open("Image File Path")

  • Resize an image using resize() method. It returns a resized copy of this image.

Syntax: 

Image.resize((width,height) , resample=3, **attr)

Python3




# Resize the image using resize() method
resize_image = image.resize((width, height))

  • Add Label and add resized image

Python3




img = ImageTk.PhotoImage(resize_image)
 
# create label and add resize image
label1 = Label(image=img)
label1.image = img
label1.pack()

Below is the implementation: 

Python3




# Import Module
from tkinter import *
from PIL import Image, ImageTk
 
# Create Tkinter Object
root = Tk()
 
# Read the Image
image = Image.open("Image File Path")
 
# Resize the image using resize() method
resize_image = image.resize((width, height))
 
img = ImageTk.PhotoImage(resize_image)
 
# create label and add resize image
label1 = Label(image=img)
label1.image = img
label1.pack()
 
# Execute Tkinter
root.mainloop()

Output:- 

250×200

In the above example, enter the file name or path at the Image File Path and enter the value of width and height according to your need.
