Tkinter PhotoImage – Displaying Images with Tkinter

Tkinter is a very well rounded GUI library with support for various GUI elements. One of the many features that Tkinter supports is the displaying of images within it’s GUI. This is accomplished using the Tkinter PhotoImage Class, which takes an image’s filepath and creates an object from it that can be used with the other GUI elements.

Using Tkinter PhotoImage

The process is quite simple. All you have to do is pass the file path of the Image you want to import, into the PhotoImage class. This creates an image object which Tkinter understands, allowing it to be used with other GUI elements like the Canvas or Labels.

Here is our PhotoImage example code:

from tkinter import * root = Tk() image = PhotoImage(file="Python.png")

We now have our image object stored in the variable image . In the section we’ll explain how to actually display this image now.

If the image you want to display is not in the same folder/directory, then you’ll have to specify the entire filepath, not just the name of the file.

Displaying the Image

As mentioned earlier, we need a suitable GUI element to actually display the image. Surprisingly, most GUI elements do support it in one way or the other. Let’s quickly go through them.

Tkinter Label (Image)

from tkinter import * root = Tk() image = PhotoImage(file="python.png") label = Label(root, image = image) label.pack() root.mainloop()

Several GUI elements, such as labels and buttons have the image parameter to which you can assign a suitable image object, just as we have down in the above code.

The output is as shown below.

Keep in mind that Tkinter itself does not have the ability to control (resize) the images it displays. The image displayed above was displayed in it’s original dimensions (size).

Displaying Images on a Canvas

The Tkinter canvas is designed to support features like drawing shapes, images and even displaying images. Hence it has a little more control over the images than the Tkinter Label does.

from tkinter import * root = Tk() image = PhotoImage(file="python.png") canvas = Canvas(width = 300, height = 300, bg='black') canvas.create_image(200, 200, image = image) canvas.pack() root.mainloop()

The first two parameters in the create_image() function represent the width and height of the image respectively. However, as you can see in the image below, that image appears to be cropped. This is because the dimensions we gave the image were too small.

Displaying Images on Buttons

Even though is a tutorial on the Tkinter PhotoImage class, I want to show you some other options as well. In the below code we use a combination of PhotoImage + Pillow (python image library) to display the image in the required format.

We open the Image using Pillow’s open() function, followed by the resize function, which takes a tuple containing the new width and height. Then we converted this image to a Tkinter compatible format using ImageTk.PhotoImage() .

from tkinter import * from PIL import Image, ImageTk root = Tk() root.geometry('200x200') image = Image.open("python.png") image = image.resize((20, 20)) image = ImageTk.PhotoImage(image) button = Button(width = 100, height = 20, image = image) button.pack(padx = 20, pady = 50) root.mainloop()

We add the final image to the button the same way we did with the labels, and we get the following output. Personally, I think it looks pretty good. Resizing it was nessacery, otherwise the image would have inflated the size of the button.

This marks the end of the Tkinter PhotoImage tutorial. Any suggestions or contributions for CodersLegacy are more than welcome. Questions regarding the tutorial content can be asked in the comments section below.

How to resize an image using Tkinter?

To process images with Tkinter and other Python packages, we generally use the Pillow Package (or PIL) in Python. It provides a way to load, process, manipulate, convert, and helps to resize the images. The package can be installed by using the command pip install Pillow. Once the package is installed, we can import it using the ‘from PIL import Image, ImageTk’ command.

To resize an image using the PIL package, we have to follow these steps −

• Install Pillow Package or PIL in the local machine.
• Open the Image using Open(image_location) method.
• Resize the given image using resize((w,h), Image. ANTIALIAS) method where ANTIALIAS removes the structural Padding from the Image around it.
• Display the Image using Canvas create_image(x,y, image) method.

Example

#Import the required Libraries from tkinter import * from PIL import Image,ImageTk #Create an instance of tkinter frame win = Tk() #Set the geometry of tkinter frame win.geometry("750x270") #Create a canvas canvas= Canvas(win, width= 600, height= 400) canvas.pack() #Load an image in the script img= (Image.open("download.png")) #Resize the Image using resize method resized_image= img.resize((300,205), Image.ANTIALIAS) new_image= ImageTk.PhotoImage(resized_image) #Add image to the Canvas Items canvas.create_image(10,10, anchor=NW, image=new_image) win.mainloop()

Output

Running the above code will display a window that will display a resized image in the Canvas.
