import tkinter as tk
from PIL import Image, ImageTk

window = tk.Tk()
canvas = tk.Canvas(window, width=500, height=500)
canvas.pack()

image_url = "https://example.com/image.jpg"  # 照片的URL
image_data = Image.open(image_url)

new_size = (300, 300)  # 新的照片大小
resized_image = image_data.resize(new_size)

tk_image = ImageTk.PhotoImage(resized_image)
canvas.create_image(0, 0, anchor=tk.NW, image=tk_image)

import tkinter as tk
from PIL import Image, ImageTk

def resize_image():
    image_url = "https://example.com/image.jpg"  # 照片的URL
    image_data = Image.open(image_url)
    new_size = (300, 300)  # 新的照片大小
    resized_image = image_data.resize(new_size)
    tk_image = ImageTk.PhotoImage(resized_image)
    canvas.create_image(0, 0, anchor=tk.NW, image=tk_image)

window = tk.Tk()
canvas = tk.Canvas(window, width=500, height=500)
canvas.pack()

resize_button = tk.Button(window, text="调整大小", command=resize_image)
resize_button.pack()

window.mainloop()
