python tkinter详解 PYTHON TKINTER Tkinter 模块(Tk 接口)是 Python 的标准 Tk GUI 工具包的接口 .Tk 和 Tkinter 可以在大多数的平台下使用,同样可以应用在 Windows 和 Mac系统里。与tkinter齐名的还有wxpython，jython，pyqt（pyqt5）。其中，公认的对python新手而言的好用程度：jython<tkinter<wxpython<pyqt。（仅代表博主所看到的意见，没有反驳的必要） Tkinter编程一个标准阅读详情

#!/usr/bin/python3.5

from tkinter import *
from tkinter import ttk
from PIL import Image, ImageTk

root = Tk()
root.title("Title")
root.geometry('600x600')

def resize_image(event):
    width = int(event.width * new_width)
    height = int(event.height * new_height)
    image = copy_of_image.resize((width, height))
    photo = ImageTk.PhotoImage(image)
    label.config(image=photo)
    label.image = photo #avoid garbage collection

def resize(w_box, h_box, pil_image):
    '''
    resize a pil_image object so it will fit into
    a box of size w_box times h_box, but retain aspect ratio
    对一个pil_image对象进行缩放，让它在一个矩形框内，还能保持比例
    '''

    w, h = pil_image.size
    f1 = 1.0 * w_box / w  # 1.0 forces float division in Python2
    f2 = 1.0 * h_box / h
    factor = min([f1, f2])
    # print(f1, f2, factor) # test
    # use best down-sizing filter
    width = int(w * factor)
    height = int(h * factor)
    return pil_image.resize((width, height), Image.ANTIALIAS)


image = Image.open('right.jpg')
pil_image = resize(root.winfo_screenwidth()*0.195, root.winfo_screenheight()*0.347, image)
w, h = pil_image.size
copy_of_image = pil_image.copy()
new_width = 1.0 * w / 600
new_height = 1.0 * h / 600
photo = ImageTk.PhotoImage(pil_image)
label = ttk.Label(root, image = photo)
label.bind('<Configure>', resize_image)
label.pack(fill=BOTH, expand = YES)
#label.place(x=300, y=300)
root.mainloop()

是tkinter新手，想问一下为什么倒数第二行加了之后原本正常显示的图片显示不出来了
