我在我的窗口中添加了一張圖片。背景顏色為白色。圖像也是白色的，但它周圍有一個環，將圖像與窗口分開。如何去除圖像周圍的黑色環？這是窗口的屏幕截圖：window = tk.Tk()window.configure()ws = window.winfo_screenwidth()hs = window.winfo_screenheight()w = 800  # width for the Tk rooth = 600  # height for the Tk rootx = (ws / 2) - (w / 2)y = (hs / 2) - (h / 2)window.geometry('%dx%d+%d+%d' % (w, h, x, y))canvas = tk.Canvas(window, bg="white", width=800, height=600)canvas.pack()canvas_scroll = tk.Scrollbar(canvas, command=canvas.yview)canvas_scroll.place(relx=1, rely=0, relheight=1, anchor=tk.NE)canvas.configure(yscrollcommand=canvas_scroll.set, scrollregion=())photo = tk.PhotoImage(file="C:/Users/sel/Desktop/logo.png")label = tk.Label(canvas, image=photo)canvas.create_window(125,10, window=label, anchor=tk.NW)l0 = tk.Label(canvas, text="??
