如何使用 PIL 模塊調整 Tkinter 中的圖像大小

Question

我得到了這個代碼，我得到了這個錯誤： AttributeError: 'PhotoImage' object has no attribute 'resize' 我也試過rgrapg = Image.open("risinggrap.jpg")我得到這個錯誤：_tkinter.TclError: image " "不存在

   rgraph = ImageTk.PhotoImage(Image.open("risinggrap.jpg"))
   rgraph = rgraph.resize((200,250),Image.ANTIALIAS)
   photoLabe = Label(x, image=rgraph)```

您需要先加載圖像，調整其大小，然后將其投射到ImageTk.PhotoImage中。 這是一個工作示例，如下所示：

import tkinter as tk
from PIL import Image, ImageTk

x = tk.Tk()

# 1. load image
image = Image.open("risinggrap.jpg")

# 2. resize it
image = image.resize((200, 250), Image.ANTIALIAS)

# 3. cast it into ImageTk.PhotoImage
rgraph = ImageTk.PhotoImage(image)

photoLabel = tk.Label(x, image = rgraph)
photoLabel.pack(side = "bottom", fill = "both", expand = "yes")
x.mainloop()
