在python中添加图片时出错

Question

我是python新手，正在使用python3.5版本。我想将photo添加到python中，下面是我编写的代码：

from tkinter import *
win=Tk()
win.title("Python Image")

canvas=Canvas(win,width=500,height=500)
canvas.pack()

my_image=PhotoImage(file="C:\\Users\\Public\\Pictures\\Sample Pictures\\Desert.jpg")
canvas.create_image(0,0,anchor=NW,image=my_image)


win.mainloop()

但是当我运行它时，出现了以下错误：

Python 3.6.4 (v3.6.4:d48eceb, Dec 19 2017, 06:04:45) [MSC v.1900 32 bit (Intel)] on win32

Answer 1

Photoimage本机只能加载png和pgm&ppm图像（http://effbot.org/tkinterbook/photoimage.htm）。你知道吗

可以通过PIL加载其他图像格式。对于python3，使用Pillow如下：

from PIL  import Image, ImageTk
from tkinter import Tk,Canvas,NW
win=Tk()
win.title("Python Image")

canvas=Canvas(win,width=500,height=500)
canvas.pack()

# use your path here ...
my_image = ImageTk.PhotoImage(Image.open(r"some.jpg"))
canvas.create_image(0,0,anchor=NW,image= my_image )

win.mainloop()
