Imagetk.photoImage无法正确显示图像

我想在tkinter GUI中显示.tif文件，但是我一直很难使图像正确加载。我能够使用image.poen ='r'正确查看图像，但是当我调用imagetk.photoimage时，它会显示一个空白的白色画布。这是代码：

def func(image_paths):
    root = Tk()
    im = Image.open(image_paths[0], mode='r')
    im.show()  # shows image correctly
    im = ImageTk.PhotoImage(im)
    im_label = Label(image=im)
    # im_label = Label(image=ImageTk.PhotoImage(Image.open(image_paths[0], mode='r')))  # This doesn't work either
    im_label.grid(row=0, column=0, columnspan=3)
    root.mainloop()

任何帮助都非常感谢！

I want to show a .tif file in a tkinter gui, but I have been having trouble getting the images to load properly. I was able to view the image correctly using Image.open with mode='r', but then when I call ImageTk.PhotoImage it displays a blank white canvas. Here is the code:

def func(image_paths):
    root = Tk()
    im = Image.open(image_paths[0], mode='r')
    im.show()  # shows image correctly
    im = ImageTk.PhotoImage(im)
    im_label = Label(image=im)
    # im_label = Label(image=ImageTk.PhotoImage(Image.open(image_paths[0], mode='r')))  # This doesn't work either
    im_label.grid(row=0, column=0, columnspan=3)
    root.mainloop()

Any help is much appreciated!

因此，最终工作的是该视频中的解决方案： https://www.youtube.com /watch？v = 6l6hdqywdh0
使其工作的代码线是：

curr = Image.open(image_paths[0], mode='r')
curr = Image.fromarray(np.uint8(cm.jet(NormalizeData(np.array(curr).astype(np.float64)))*255))
curr = ImageTk.PhotoImage(curr)

So, what ended up working was the solution in this video: https://www.youtube.com/watch?v=6l6HDQyWdH0
The lines of code that got it to work was:

curr = Image.open(image_paths[0], mode='r')
curr = Image.fromarray(np.uint8(cm.jet(NormalizeData(np.array(curr).astype(np.float64)))*255))
curr = ImageTk.PhotoImage(curr)
