AttributeError:“PhotoImage”对象没有属性“size”

Question

首先，我打开并使用

img = Image.open("C:\\users\\zouaoua\\PycharmProjects\\image\\lenna.png")
photo = ImageTk.PhotoImage(img)
canvas.config(height=photo.height(), width=photo.width())
canvas.create_image(0, 0, anchor=NW, image=photo)
canvas.pack()

我想以我使用的负片方式重新拍摄图像

def retation_negative(image):
global im

L, H = image.size
im2 = Image.new("RGB", (L, H))
for y in range(H):
    # print(x)
    for x in range(L):
        p = image.getpixel((y, x))
        im2.putpixel((x, y), p)
im = ImageTk.PhotoImage(im2)
canvas.config(height=im.height(), width=im.width())
canvas.create_image(0, 0, anchor=NW, image=im)

submenu = Menu(second_menu, tearoff=0)
submenu.add_command(label="negatve", command=retation_negative(img))

但是当我运行代码时，我得到了这个错误，我不知道为什么我这么困惑
