Python3用tkinter和PIL实现看图工具

#encoding=utf-8
import tkinter as tk
from PIL import Image, ImageTk

class App(tk.Frame):
  def __init__(self, master=None):
    super().__init__(master, width=400, height=300)
    self.pack()
    self.pilImage = Image.open("CSDN.png")
    self.tkImage = ImageTk.PhotoImage(image=self.pilImage)
    self.label = tk.Label(self, image=self.tkImage)
    self.label.pack()

  def processEvent(self, event):
    pass

if __name__ == '__main__':
  root = tk.Tk()
  app = App(root)
  root.mainloop()
