從本地文件夾中選取一張圖片并在canvas上顯示

from tkinter import *

from tkinter import filedialog

from PIL import Image, ImageTk

if __name__ == "__main__":

root = Tk()

#setting up a tkinter canvas with scrollbars

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

frame.grid_rowconfigure(0, weight=1)

frame.grid_columnconfigure(0, weight=1)

xscroll = Scrollbar(frame, orient=HORIZONTAL)

xscroll.grid(row=1, column=0, sticky=E+W)

yscroll = Scrollbar(frame)

yscroll.grid(row=0, column=1, sticky=N+S)

canvas = Canvas(frame, bd=0, xscrollcommand=xscroll.set, yscrollcommand=yscroll.set)

canvas.grid(row=0, column=0, sticky=N+S+E+W)

xscroll.config(command=canvas.xview)

yscroll.config(command=canvas.yview)

frame.pack(fill=BOTH,expand=1)

#function to be called when mouse is clicked

def printcoords():

File = filedialog.askopenfilename(parent=root, initialdir="C:/",title='Choose an image.')

filename = ImageTk.PhotoImage(Image.open(File))

canvas.image = filename # <--- keep reference of your image

canvas.create_image(0,0,anchor='nw',image=filename)

Button(root,text='choose',command=printcoords).pack()

root.mainloop()
