Trouble importing a png image with PIL

Question

I want to import a png image but i'm unable to write imagetype as an argument for the Image function the correct way. I've tried writing "png", "PNG", imgtype="png" but it wont work. Does anybody know how to write this correctly. I'm using the code below. I'm using OSX btw.

from Tkinter import *
import PIL

root = Tk()
img = Image("this is where i'm supppsed to write imgtype", file="image.png")
panel = Canvas(root)
panel.pack(side = "bottom", fill = "both", expand = "yes")
panel.create_image(image=img)

root.mainloop()

You are trying to create an image from tkinters Image class but it doesn't support .png images.

From the documentation :

The PhotoImage class can read GIF and PGM/PPM images from files:

 photo = PhotoImage(file="image.gif") 

If you need to work with other file formats, the Python Imaging Library (PIL) contains classes that lets you load images in over 30 formats, and convert them to Tkinter-compatible image objects:

 from PIL import Image, ImageTk image = Image.open("lenna.jpg") photo = ImageTk.PhotoImage(image) 

By doing from Tkinter import * , you are loading all modules from the Tkinter package into the global namespace, so Image in your case is actually Tkinter.Image .

To fix your issue, try:

pil_img = PIL.Image.open("image.png")
img = PIL.ImageTk.PhotoImage(pil_img)
