如何在Python中的tk标签上从网页显示png文件? [英] How to display a png file from a webpage on a tk label in Python?

问题描述

我是python的新手，并且在Windows 7 64位上使用python 3.3.我可以使用以下代码显示gif图像.但是我不能使其与png文件一起使用.怎么做?谢谢.

import urllib
import urllib.request
import tkinter as tk
root = tk.Tk()
url = "http://www.baidu.com/img/bdlogo.gif"
u = urllib.request.urlopen(url)
raw_data = u.read()
u.close()
import base64
b64_data = base64.encodestring(raw_data)
image = tk.PhotoImage(data=b64_data)
label = tk.Label(image=image)
label.pack()

解决方案

您应使用PIL(或枕头).您可以在此处找到.

在安装枕头后尝试以下示例:

from io import BytesIO
import urllib
import urllib.request
import tkinter as tk
from PIL import Image, ImageTk
root = tk.Tk()
url = "http://imgs.xkcd.com/comics/python.png"
with urllib.request.urlopen(url) as u:
    raw_data = u.read()
im = Image.open(BytesIO(raw_data))
image = ImageTk.PhotoImage(im)
label = tk.Label(image=image)
label.pack()
root.mainloop()

I'm new to python and I'm on a windows 7 64 bit with python 3.3. I can display a gif image with the following code. However I can't make it work with png files. How to do that? Thanks.

import urllib
import urllib.request
import tkinter as tk
root = tk.Tk()
url = "http://www.baidu.com/img/bdlogo.gif"
u = urllib.request.urlopen(url)
raw_data = u.read()
u.close()
import base64
b64_data = base64.encodestring(raw_data)
image = tk.PhotoImage(data=b64_data)
label = tk.Label(image=image)
label.pack()

解决方案

You should use PIL (or pillow). You can find pillow windows binary here.

Try following example after you install pillow:

from io import BytesIO
import urllib
import urllib.request
import tkinter as tk
from PIL import Image, ImageTk
root = tk.Tk()
url = "http://imgs.xkcd.com/comics/python.png"
with urllib.request.urlopen(url) as u:
    raw_data = u.read()
im = Image.open(BytesIO(raw_data))
image = ImageTk.PhotoImage(im)
label = tk.Label(image=image)
label.pack()
root.mainloop()
