如何在GUI中使用Tkinter显示图像

Question

The given code is not working, as it gives the error of file not found for 'haridwar.jpg' though I tried putting it in in Python35 and also on desktop. Please help

import tkinter as tk  
from PIL import Image,ImageTk  
root = tk.Tk()  
root.title("display image")  
im=Image.open("haridwar.jpg")  
photo=ImageTk.PhotoImage(im)  
cv = tk.Canvas()  
cv.pack(side='top', fill='both', expand='yes')  
cv.create_image(10, 10, image=photo, anchor='nw')  
root.mainloop()

Judging by your question you might not have the file in a good location; also you are not providing a path to those locations. So lets break it down a little.

You said you placed the image in the Python35 folder. Without knowing more I would imagine you are talking about the python default directory located somewhere like C:\\program files\\Python35 .

If this is the case then change the line:

im=Image.open("haridwar.jpg") 

To this:

im=Image.open("C:\program files\Python35\haridwar.jpg")

though this is not a good place for your image. We will get to that in a sec.

As you stated you also tried your desktop. So you would want to provide a path to your desktop.

Something like this:

im=Image.open("C:/Users/your_user_folder/Desktop/haridwar.jpg")

This is also not a great place for your file.

Lets try something else. Lets put the file inside your working python directory.

For example if your main.py file is located inside of

"C:/myworkspace/my_program/main.py"

then you can place that image in the same my_program folder and your code should work as is.

If you want to have a folder just for images you could have one in a directory that looks like this:

"C:/myworkspace/my_program/my_images/haridwar.jpg"

In this case you can provide a short path like this:

im=Image.open("./my_images/haridwar.jpg") 

notice the . before the /my_image folder. This is used to tell Python it can look inside its current working directory for the folder.

I tried your code using a directory/filename i know was correct, and it works. You have an error in the spelling of your directory/filename or you got the directory wrong.

Make sure you have the directory and file name correct.

For example, I have "Image.jpg" on my desktop

import tkinter as tk  
from PIL import Image,ImageTk  
root = tk.Tk()  
root.title("display image")  
im=Image.open("C:/Users/<myname>/Desktop/Image.jpg")  #This is the correct location and spelling for my image location
photo=ImageTk.PhotoImage(im)  
cv = tk.Canvas()  
cv.pack(side='top', fill='both', expand='yes')  
cv.create_image(10, 10, image=photo, anchor='nw')  
root.mainloop()
