我試圖在畫布上滾動一個jpeg,但我似乎無法讓我的滾動條工作。下面是一些示例代碼:在Tkinter畫布上的.jpg圖像的滾動條在Python中

from Tkinter import * 
import Image, ImageTk 

root = Tk() 

frame = Frame(root, bd=2, relief=SUNKEN) 

frame.grid_rowconfigure(0, weight=1) 
frame.grid_columnconfigure(0, weight=1) 

xscrollbar = Scrollbar(frame, orient=HORIZONTAL) 
xscrollbar.grid(row=1, column=0, sticky=E+W) 

yscrollbar = Scrollbar(frame) 
yscrollbar.grid(row=0, column=1, sticky=N+S) 

canvas = Canvas(frame, bd=0, xscrollcommand=xscrollbar.set, yscrollcommand=yscrollbar.set) 
canvas.grid(row=0, column=0, sticky=N+S+E+W) 

File = "jpg filepath here" 
img = ImageTk.PhotoImage(Image.open(File)) 
canvas.create_image(0,0,image=img, anchor="nw") 

xscrollbar.config(command=canvas.xview) 
yscrollbar.config(command=canvas.yview) 

frame.pack() 
root.mainloop()
