How to Control the Size Of A Picture Using Tkinter?

a minute read

To control the size of a picture using tkinter, you can use the Image.resize() method to scale the image to a desired width and height. First, import the PIL module with PIL.Image and PIL.ImageTk, then open the image using Image.open(). Next, create a reference to the image using PhotoImage(), and resize the image using the resize() method with the desired width and height. Finally, display the resized image on a tkinter window or canvas using create_image() or Label(). This will allow you to control the size of the picture within your tkinter application.


What units are used to set image size in tkinter?

Image size in tkinter is typically set using pixels.


What is the default image scaling algorithm used in tkinter?

The default image scaling algorithm used in tkinter is NEAREST. This algorithm does not provide any smoothing or interpolation, resulting in a pixelated or jagged appearance when scaling images up or down.


How to check the current size of an image in tkinter?

You can check the current size of an image in tkinter using the width() and height() methods of the PhotoImage object. Here is an example code snippet that demonstrates how to do this:

import tkinter as tk

root = tk.Tk()

# Load the image
image = tk.PhotoImage(file="image.png")

# Get the width and height of the image
width = image.width()
height = image.height()

print("Image width:", width)
print("Image height:", height)

root.mainloop()


This code will load an image called "image.png" and then print out its width and height. You can replace "image.png" with the path to your own image file.
