In order to work with images, Python Library provides Pillow or PIL package that enables applications to import images and perform various operations on them.
Let us suppose that we want to resize an image dynamically to its window. In such case, we have to follow these steps −
Open the Image in the Tkinter Application.
Create a Canvas Widget and use create_image(**options) to place the loaded image in the canvas.
Define a function to resize the loaded image.
Bind the function with the parent window configuration.
# Import the required libraries from tkinter import * from PIL import ImageTk, Image # Create an instance of Tkinter Frame win = Tk() # Set the geometry of Tkinter Frame win.geometry("700x450") # Open the Image File bg = ImageTk.PhotoImage(file="tutorialspoint.png") # Create a Canvas canvas = Canvas(win, width=700, height=3500) canvas.pack(fill=BOTH, expand=True) # Add Image inside the Canvas canvas.create_image(0, 0, image=bg, anchor='nw') # Function to resize the window def resize_image(e): global image, resized, image2 # open image to resize it image = Image.open("tutorialspoint.png") # resize the image with width and height of root resized = image.resize((e.width, e.height), Image.ANTIALIAS) image2 = ImageTk.PhotoImage(resized) canvas.create_image(0, 0, image=image2, anchor='nw') # Bind the function to configure the parent window win.bind("<Configure>", resize_image) win.mainloop()
Running the above code will display a window containing an image which can be dynamically resized.
