如何在Tkinter中更改图像的分辨率？

from PIL import Image, ImageTk
import tkinter as tk

root = tk.Tk()
canvas = tk.Canvas(root, width=800, height=600)
canvas.pack()

image = Image.open("image.jpg")  # 替换为你的图像文件路径
new_image = image.resize((new_width, new_height))  # 替换为你想要的新的宽度和高度

tk_image = ImageTk.PhotoImage(new_image)

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

from PIL import Image, ImageTk
import tkinter as tk

def change_resolution():
    image = Image.open("image.jpg")  # 替换为你的图像文件路径
    new_image = image.resize((new_width, new_height))  # 替换为你想要的新的宽度和高度
    tk_image = ImageTk.PhotoImage(new_image)
    canvas.create_image(0, 0, anchor=tk.NW, image=tk_image)

root = tk.Tk()
canvas = tk.Canvas(root, width=800, height=600)
canvas.pack()

button = tk.Button(root, text="更改分辨率", command=change_resolution)
button.pack()

root.mainloop()
