如何给这段代码添加背景图片,加入到程序去import tkinter as tk import numpy as np def change_label(): button.destroy() label.config(text="请输入您的身高体重以及目标体重:") height_label.place(relx=0.5, rely=0.4, anchor="center") height_entry.place(relx=0.5, rely=0.45, anchor="center") weight_label.place(relx=0.5, rely=0.5, anchor="center") weight_entry.place(relx=0.5, rely=0.55, anchor="center") target_label.place(relx=0.5, rely=0.6, anchor="center") target_entry.place(relx=0.5, rely=0.65, anchor="center") submit_button.place(relx=0.5, rely=0.8, anchor="center")

可以使用tkinter中的Canvas控件来添加背景图片。以下是添加背景图片的示例代码:
```python
import tkinter as tk
from PIL import Image, ImageTk
root = tk.Tk()
# 加载图片
image = Image.open("background.jpg")
background_image = ImageTk.PhotoImage(image)
# 创建Canvas控件来显示图片
canvas = tk.Canvas(root, width=500, height=500)
canvas.pack(fill="both", expand=True)
canvas.create_image(0, 0, image=background_image, anchor="nw")
# 创建其他控件
label = tk.Label(canvas, text="请输入您的身高体重以及目标体重:")
height_label = tk.Label(canvas, text="身高:")
height_entry = tk.Entry(canvas)
weight_label = tk.Label(canvas, text="体重:")
weight_entry = tk.Entry(canvas)
target_label = tk.Label(canvas, text="目标体重:")
target_entry = tk.Entry(canvas)
submit_button = tk.Button(canvas, text="提交")
# 显示控件
label.place(relx=0.5, rely=0.4, anchor="center")
height_label.place(relx=0.5, rely=0.45, anchor="center")
height_entry.place(relx=0.5, rely=0.5, anchor="center")
weight_label.place(relx=0.5, rely=0.55, anchor="center")
weight_entry.place(relx=0.5, rely=0.6, anchor="center")
target_label.place(relx=0.5, rely=0.65, anchor="center")
target_entry.place(relx=0.5, rely=0.7, anchor="center")
submit_button.place(relx=0.5, rely=0.8, anchor="center")
root.mainloop()
```
在上面的代码中,我们首先加载了一张图片,然后使用Canvas控件来显示这张图片。然后,我们创建其他控件,并使用place()方法来显示它们。需要注意的是,我们在使用place()方法时,要把控件放在Canvas控件内部,而不是放在root窗口内部。
