通过Pillow处理JPG格式

编程问答 2022-06-09

问题描述

from tkinter import *
from glob import glob
import demoCheck
import random
import quitter
from PIL import ImageTk

gifdir = 'd:/Python/Jupyter/Programming Python/Chap 8 - GUI/pic/'


class buttonpics(Frame):
    def __init__(self,parent=None,dir='./gifs/',**kwargs):
        Frame.__init__(self,parent,**kwargs)
        self.pack()
        self.lbl = Label(self,text='None',bg='blue',fg='red')
        self.lbl.pack(fill=BOTH)
        self.btn = Button(self,text='Press me',bg='white',command=self.draw)
        self.btn.pack()
        self.quitter = quitter.Quitter(self)
        self.quitter.pack(anchor=S)
        self.files = glob(dir+'*.jpg')
        self.images = [(file,ImageTk.PhotoImage(file=file))
                       for file in self.files]

    def draw(self):
        name,photo = random.choice(self.images)
        self.btn.config(image=photo)
        self.lbl.config(text=name)


buttonpics(dir=gifdir).mainloop()

代码正在尝试通过Pillow的ImageTk模块将jpg格式的图片加载到Tkinter。但是，系统生成以下错误：

> Traceback (most recent call last):   File
> "d:/Python/Jupyter/Programming Python/Chap 8 -
> GUI/buttonpics-func.py",line 31,in <module>

如果扩展名更改为png，则程序可以平稳运行。这是由于jpg格式的兼容性问题还是其他一些原因引起的？谢谢您的帮助！
