Python的龜：如何打開圖形

Question

我有借鑑了Canvas部件龜的項目。我已經知道如何保存繪圖，但是如何打開它們。這是我想說的一個例子：

from tkinter import * 
root = Tk() 
... #Just creating widgets 

def openDrawing: 

...#What goes in here ? 

fileMenu.add_command(label = "Open Drawing",command=openDrawing,accelerator="Ctrl+O") 

root.mainloop() 

Answer 1

包含圖像數據的PostScript文件格式爲supported由PIL庫。所以，你可以打開你的龜.ps文件是這樣的：

import PIL 

# Load the .ps file using PIL 
ps_file = PIL.Image.open("turtle_file.ps") 
ps_turtle = PIL.ImageTk.PhotoImage(ps_file) 
... 
... 
# Let us suppose you want to display it on a label 
label = Label(image=ps_turtle) 
label.image = ps_turtle # keep a reference 
label.pack()
