Python使用tkinter加载png、jpg等图片

首先PhotoImage注意这里只支持gif格式的图片

photo = PhotoImage(file="D:/python/images/02.gif")

发现tkinter是只支持gif的格式，如果要加载png或者jpg的话就要使用PIL模块

from tkinter import *
from PIL import Image, ImageTk

root = Tk()
root.title('测试组python毕业题')

img = Image.open('ques.png')  # 打开图片
photo = ImageTk.PhotoImage(img)  # 用PIL模块的PhotoImage打开
imglabel = Label(root, image=photo)
imglabel.grid(row=0, column=0, columnspan=3)

Label(root, text="Answer:").grid(row=1, column=0, sticky=S + N)

answerEntry = Entry(root)
btn = Button(root, text="Submit", command='submit')

answerEntry.grid(row=1, column=1)
btn.grid(row=1, column=2)

mainloop()

但运行时会报

ModuleNotFoundError: No module named 'PIL'

运行命令:

pip install pillow

D:\Program Files\Python37>pip install pillow
Collecting pillow

     |????????????????????????????????| 2.0MB 133kB/s
Installing collected packages: pillow
Successfully installed pillow-6.0.0

D:\Program Files\Python37>

如果运行该命令 显示

Requirement already satisfied: Pillow in c:\program files (x86)\python\lib\site-packages (3.4.2)

则表示已经安装过了

如果已安装则先卸载以获取最新的pillow
运行命令: pip uninstall pillow
然后运行:pip install pillow
就可以了

补充：解决python tkinter 展示jpg、png格式图片的问题

报错：

from tkinter import *
 
img = PhotoImage(file = r'D:\test\hero\暗黑元首\暗黑元首.jpg')
lable_show = Label(frame_show,imag = img)

解决：首先安装PIL库，使用pip命令

pip install pillow

然后使用PIL库获得ImageTk.PhotoImage对象代替tk.PhotoImage对象即可

from PIL import Image,ImageTk
 
img = ImageTk.PhotoImage(Image.open(r'D:\test\hero\暗黑元首\暗黑元首.jpg'))
lable_show = Label(frame_show,imag = img)
