TKinter, how to place a thumbnail of an image?

Question

Python

Good day to all!
I display the image using the Label widget
If I hardcode the dimensions of the image, then the problem is that the image is not visible to the whole, but only a part (the center of the image, if the image is larger than the form or widget on which it is displayed). I have tried all possible options, tried using pack, place and grid.
Tell me, how can I achieve such an effect that the displayed image decreases (or stretches), proportionally, with a change in the size of the parent form? Really the only option is to resize the image before displaying it on the form?

Try like this:

from tkinter import *
from PIL import Image, ImageTk

class App(Frame):
    def __init__(self, master):
        Frame.__init__(self, master)
        self.columnconfigure(0,weight=1)
        self.rowconfigure(0,weight=1)
        self.original = Image.open('image.jpeg')
        self.image = ImageTk.PhotoImage(self.original)
        self.display = Canvas(self, bd=0, highlightthickness=0)
        self.display.create_image(0, 0, image=self.image, anchor=NW, tags="IMG")
        self.display.grid(row=0, sticky=W+E+N+S)
        self.pack(fill=BOTH, expand=1)
        self.bind("<Configure>", self.resize)

    def resize(self, event):
        size = (event.width, event.height)
        resized = self.original.resize(size,Image.ANTIALIAS)
        self.image = ImageTk.PhotoImage(resized)
        self.display.delete("IMG")
        self.display.create_image(0, 0, image=self.image, anchor=NW, tags="IMG")

root = Tk()
app = App(root)
app.mainloop()
