英文:
Tkinter images and geometry creation
问题
以下是您提供的代码的翻译部分：
from tkinter import *
from PIL import ImageTk, Image
import tkinter as tk
app = Tk()
app.title("欢迎")
img = Image.open('C:\\Users\\Stefa\\Downloads\\galaxy.jpeg')
bg = ImageTk.PhotoImage(img)
canvas_width = 800
canvas_height = 800
master = tk.Tk()
label = Label(app, image=bg)
label.place(x=0, y=0)
label2 = Label(app, text="欢迎来到我们的星系",
font=("Times New Roman", 24))
label2.pack(pady=50)
app.geometry(f"{canvas_width}x{canvas_height}")
can_widget = Canvas(app, width=canvas_width, height=canvas_height)
can_widget.pack()
points = [200, 20, 80, 396, 380, 156, 20, 156, 320, 396]
can_widget.create_polygon(points, outline='red', fill='cyan', width=6)
app.mainloop()
然而，当我运行它时，我希望星星位于背景图像之上。有解决方案吗？谢谢。
英文:
I've tried to do a star fractal drawing a star using tkinter and putting an image as a background.
from tkinter import *
from PIL import ImageTk, Image
import tkinter as tk
app = Tk()
app.title("Welcome")
img =Image.open('C:\\Users\\Stefa\\Downloads\\galaxy.jpeg')
bg = ImageTk.PhotoImage(img)
canvas_width=800
canvas_height=800
master = tk.Tk()
label = Label(app, image=bg)
label.place(x = 0,y = 0)
label2 = Label(app, text = "WELCOME TO OUR GALAXY",
font=("Times New Roman", 24))
label2.pack(pady = 50)
app.geometry(f"{canvas_width}x{canvas_height}")
can_widgt=Canvas(app, width=canvas_width, height= canvas_height)
can_widgt.pack()
points=[200,20,80,396,380,156,20,156,320,396]
can_widgt.create_polygon(points, outline='red',fill='cyan', width=6)
app.mainloop()
That's the code
However when i run it i want the star to be upon the background image. Any solutions for this ? Thanks

你需要将图像创建为画布对象，而不是标签。
例如，这将图像添加到画布的左上角，并在其上绘制：
can_widgt.create_image(0, 0, anchor="nw", image=bg)
英文:
You need to create the image as a canvas object rather than as a label.
For example, this add the image to the top-left corner of the canvas, with the drawing on top of it:
can_widgt.create_image(0, 0, anchor="nw", image=bg)

你明确地错过了@BryanOakley提供的那一行代码（+1），但总体上你有太多冗余的代码（例如，两个根窗口，两个不同的几何管理器）：
import tkinter as tk
from PIL import ImageTk, Image
canvas_width = 800
canvas_height = 800
root = tk.Tk()
root.title("Welcome")
img = Image.open(r'C:\Users\Stefa\Downloads\galaxy.jpeg')
bg = ImageTk.PhotoImage(img)
label = tk.Label(root, text="WELCOME TO OUR GALAXY", font=("Times New Roman", 24))
label.pack(pady=50)
can_widgt = tk.Canvas(root, width=canvas_width, height=canvas_height)
can_widgt.pack()
can_widgt.create_image(0, 0, anchor="nw", image=bg)
points = [200, 20, 80, 396, 380, 156, 20, 156, 320, 396]
can_widgt.create_polygon(points, outline='red', fill='cyan', width=6)
root.mainloop()
英文:
You're specifically missing the line of code that @BryanOakley provides (+1) but in general you have too much redundant code (e.g. two roots, two different geomentry managers):
import tkinter as tk
from PIL import ImageTk, Image
canvas_width = 800
canvas_height = 800
root = tk.Tk()
root.title("Welcome")
img = Image.open(r'C:\Users\Stefa\Downloads\galaxy.jpeg')
bg = ImageTk.PhotoImage(img)
label = tk.Label(root, text="WELCOME TO OUR GALAXY", font=("Times New Roman", 24))
label.pack(pady=50)
can_widgt = tk.Canvas(root, width=canvas_width, height=canvas_height)
can_widgt.pack()
can_widgt.create_image(0, 0, anchor="nw", image=bg)
points = [200, 20, 80, 396, 380, 156, 20, 156, 320, 396]
can_widgt.create_polygon(points, outline='red', fill='cyan', width=6)
root.mainloop()
