无法从 TKinter 的 URL 加载图像 [英] Unable to Load an Image from an URL at TKinter

问题描述

我的目标是使用 tkinter python 显示来自 URL 的 JPG 图像.

这是 stackoverflow 链接，我用作参考.但是当我尝试运行代码时，我收到了一堆错误，例如:

• 密钥错误:b'R0l......
• AttributeError: 'PhotoImage' 对象没有属性 '_PhotoImage__photo'

有没有人有解决办法?

这是代码:

导入 tkinter 作为 tk从 PIL 导入 Image、ImageTk从 urllib.request 导入 urlopen导入 base64根 = tk.Tk()URL = "http://www.universeofsymbolism.com/images/ram-spirit-animal.jpg"u = urlopen(URL)原始数据 = u.read()u.close()b64_data = base64.encodestring(raw_data)照片 = ImageTk.PhotoImage(b64_data)标签 = tk.Label(图像=照片)label.image = 照片标签.pack()root.mainloop()

解决方案

第一个错误是没有在 ImageTk.PhotoImage(data=b64_data) 中指定 data 参数.但是，我不确定为什么 PhotoImage 无法读取 base64 数据.

一种解决方法是使用 io 模块中的 BytesIO.您可以将从图像中读取的原始数据传入BytesIO，在Image 中打开它，然后将其传入PhotoImage.>

我从这里找到了打开图片的代码.

导入 tkinter 作为 tk从 PIL 导入 Image、ImageTk从 urllib2 导入 urlopen从 io 导入 BytesIO根 = tk.Tk()URL = "http://www.universeofsymbolism.com/images/ram-spirit-animal.jpg"u = urlopen(URL)原始数据 = u.read()u.close()im = Image.open(BytesIO(raw_data))照片 = ImageTk.PhotoImage(im)标签 = tk.Label(图像=照片)label.image = 照片标签.pack()root.mainloop()

如果有人对编码失败的原因有更好的答案，这将是对这个问题的更合适的答案.

My goal is to display an JPG image from an URL using tkinter python.

This is the stackoverflow link that I used as a reference. But when I try to run the code, I have received a bunch of error such as:

• KeyError: b'R0l.......
• AttributeError: 'PhotoImage' object has no attribute '_PhotoImage__photo'

Does anyone have the solution to this?

This is the code:

import tkinter as tk
from PIL import Image, ImageTk
from urllib.request import urlopen
import base64

root = tk.Tk()

URL = "http://www.universeofsymbolism.com/images/ram-spirit-animal.jpg"
u = urlopen(URL)
raw_data = u.read()
u.close()


b64_data = base64.encodestring(raw_data)
photo = ImageTk.PhotoImage(b64_data)

label = tk.Label(image=photo)
label.image = photo
label.pack()

root.mainloop()

解决方案

The first error is not specifying the data parameter within ImageTk.PhotoImage(data=b64_data). However, I'm unsure why PhotoImage is unable to read base64 data.

A workaround would be to use BytesIO from the io module. You can pass in the raw data you read from the image into a BytesIO, open it in Image and then pass that into PhotoImage.

I found the code for opening the image from here.

import tkinter as tk
from PIL import Image, ImageTk
from urllib2 import urlopen
from io import BytesIO

root = tk.Tk()

URL = "http://www.universeofsymbolism.com/images/ram-spirit-animal.jpg"
u = urlopen(URL)
raw_data = u.read()
u.close()

im = Image.open(BytesIO(raw_data))
photo = ImageTk.PhotoImage(im)

label = tk.Label(image=photo)
label.image = photo
label.pack()

root.mainloop()

If anybody has a better answer as to why the encoding fails, it would be a more appropriate answer to this question.
