Tkinter错误:无法识别图像文件中的数据 [英] Tkinter error: Couldn't recognize data in image file

问题描述

我正在尝试将jpg图像放到tkinter画布上. tkinter给我这个错误:

I'm trying to put a jpg image to a tkinter canvas. tkinter gives me this error:

无法识别图像文件中的数据

couldn't recognize data in image file

我使用文档中的代码:

canv = Canvas(root, width=80, height=80, bg='white')
canv.grid(row=2, column=3)

img = PhotoImage(file="bll.jpg")
canv.create_image(20,20, anchor=NW, image=img)

与png图像相同.甚至试图将图像放入标签小部件中，但出现了相同的错误.怎么了?

Same thing with png images. Even tried to put an image into a label widget, but got the same error. What's wrong?

我在Mac上使用的是Python 3. Python文件和图像位于同一文件夹中.

I am using Python 3 on Mac. Python file and image are in the same folder.

推荐答案

您的代码似乎正确，这在Windows 7(Python 3.6)上为我运行:

Your code seems right, this is running for me on Windows 7 (Python 3.6):

from tkinter import *
root = Tk()

canv = Canvas(root, width=80, height=80, bg='white')
canv.grid(row=2, column=3)

img = PhotoImage(file="bll.jpg")
canv.create_image(20,20, anchor=NW, image=img)

mainloop()

产生此tkinter GUI:

resulting in this tkinter GUI:

，其图像为bll.jpg:

(imgur将其转换为bll.png，但这也对我有用.)

(imgur converted it to bll.png but this is working for me as well.)

更多选项:

• 此答案提到，tkinter仅适用于gif图像.尝试使用.gif图片.
• 如果这不起作用，请按照此答案中的说明使用PIL.

• This answer mentions, tkinter is working only with gif images. Try using a .gif image.
• If this is not working, use PIL as stated in this answer.

更新:使用PIL的解决方案:

from tkinter import *
from PIL import ImageTk, Image
root = Tk()

canv = Canvas(root, width=80, height=80, bg='white')
canv.grid(row=2, column=3)

img = ImageTk.PhotoImage(Image.open("bll.jpg"))  # PIL solution
canv.create_image(20, 20, anchor=NW, image=img)

mainloop()
