如何更改画布中的图像？[python tkinter] [英] How to change image in canvas?[python tkinter]

问题描述

如下所示，我想使用tkinter在画布上显示图像，并且当单击按钮时，应该显示另一张照片。但是我失败了。第一张图片显示得很好，但是当我单击按钮时，图片没有改变

As below, I want to show an image in canvas using tkinter, and when a click the button, an other photo should be shown. But I failed. The first image shows well, but the image didn't change when I click the button

C = Tkinter.Canvas(top, bg="#fff", height=500, width=600)

// show image1 in canvas first and it works
itk = ImageTk.PhotoImage(img1)
C.create_image(300, 250, image=itk)
C.pack()


def changeImage():
    // I want to show image2 in canvas, but I fails
    print 'change image in canvas'
    itk2 = ImageTk.PhotoImage(img2)
    C.create_image(300, 250, image=itk2)

button = Tkinter.Button(top,text='click', command=changeImage)
button.pack()


top.mainloop()

推荐答案

    itk2 = ImageTk.PhotoImage(img2)
