AttributeError: ‘PhotoImage’ object has no attribute ‘_PhotoImage__photo’
The ‘AttributeError: ‘PhotoImage’ object has no attribute ‘_PhotoImage__photo” error occurs when you are trying to access the _photo attribute of a PhotoImage object, but it is not defined.
The PhotoImage class is provided by the tkinter module in Python. It is used to display images in a Tkinter application. When you create a PhotoImage object, it internally creates a _photo attribute to store the image data.
Here’s an example that demonstrates the error:
import tkinter as tk
from PIL import Image, ImageTk
root = tk.Tk()
# Open an image file
image = Image.open("example.jpg")
photo = ImageTk.PhotoImage(image)
# Access the _photo attribute (generates the error)
photo._photo
root.mainloop()
In the above example, we first import the necessary modules (tkinter and PIL). Then, we open an image file using the Image.open() method from the PIL module. We create a PhotoImage object using ImageTk.PhotoImage() passing the opened image as an argument. Finally, we try to access the _photo attribute which results in the mentioned error.
To avoid this error, you should not try to access the _photo attribute directly. The PhotoImage class provides several methods to manipulate and display images. You can use these methods to perform various operations on the image.
# Accessing pixels of the image using the put() method
photo.put((255, 0, 0), (0, 0)) # Set pixel at (0, 0) to red
photo.put((0, 255, 0), (10, 10)) # Set pixel at (10, 10) to green
# Displaying the image in a Label widget
label = tk.Label(root, image=photo)
label.pack()
root.mainloop()
In this modified example, we used the put() method of the PhotoImage class to manipulate the image by setting specific pixels to certain colors. We then displayed the image in a Label widget using the image parameter.
Remember to adapt these examples to your specific use case, including specifying the correct path to the image file you want to open.
