Python 3.7、tkinter、jpg:无法识别图像文件中的数据 [英] Python 3.7, tkinter, jpg: couldn't recognize data in image file

问题描述

我想就 python3 中的 tkinter 寻求一些帮助.我似乎无法使用以下代码在标签中显示 jpeg 图像文件:

I wanted to ask some help regarding tkinter, in python3. I can't seem to display a jpeg image file in a label using the following code:

def changephoto(self):
    self.tmpimgpath = filedialog.askopenfilename(initialdir=os.getcwd())
    self.installimagepath.set(self.tmpimgpath)
    self.selectedpicture = PhotoImage(file=self.installimagepath.get())
    self.PictureLabel.configure(image=self.selectedpicture)

它可以很好地处理 png 图像，但是当我尝试加载 jpg 图像时，我只能得到以下错误:

It can do png Images just fine, but when I try to load a jpg image, all I i am able to get is the following error:

_tkinter.TclError: couldn't recognize data in image file

我经历了所有我能找到的类似问题，但他们似乎都回答了同样的问题:from PIL import ImageTk, Image"当我尝试这样做时(目前，我正在尝试使用枕头，顺便说一句)，ImageTk 似乎不可用.

I went through all similar questions I could find, but they all seem to answer the same thing: "from PIL import ImageTk, Image" When I try that ( for the moment, I am trying to use pillow, btw ), ImageTk doesn't seem to be available.

任何帮助将不胜感激.

推荐答案

1. 你必须安装PIL:pip installpil.

如果pip没有成功安装pillow，你可能需要尝试pip3或pip3.7 (使用 bash 查看您有哪些选项)

If pip does not successfully install pillow, you might have to try pip3 or pip3.7 (use bash to see which options you have)

您可以使用 ImageTk 打开您的图像:

You can open your image with ImageTk:

import os
import tkinter as tk
from tkinter import filedialog
from PIL import ImageTk

def changephoto():
   root = tk.Tk()
   PictureLabel= tk.Label(root)
   PictureLabel.pack()
   tmpimgpath = filedialog.askopenfilename(initialdir=os.getcwd())
   selectedpicture= ImageTk.PhotoImage(file=tmpimgpath)
   PictureLabel.configure(image=selectedpicture)
