我如何使用 PIL 模块在 Tkinter 中调整图像大小

Question

我得到了这段代码，但出现了这个错误：AttributeError: 'PhotoImage' object has no attribute 'resize rgrapg = Image.open("risinggrap.jpg")'

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

您需要先加载图像，调整大小，然后将其转换为ImageTk.PhotoImage. 这是一个像这样的工作示例：

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()
