我真的希望对此有所帮助，因为它让我非常难过。我有自己的代码，如下所示：
from tkinter import *
from PIL import ImageTk
dam_level = [75]
c = Canvas(width = 200, height = 235, relief = "sunken", borderwidth = 2)
c.grid(row = 11, rowspan = 8, column = 4, columnspan = 2)
c_width = 200
c_height = 250
y_stretch = 1.9
y_gap = 35
x_stretch = 15
x_width = 90
x_gap = 30
for x, y in enumerate(dam_level):
x0 = x * x_stretch + x * x_width + x_gap
y0 = c_height - (y * y_stretch + y_gap)
x1 = x * x_stretch + x * x_width + x_width + x_gap
y1 = c_height - y_gap
c.create_rectangle(x0, y0, x1, y1, fill = "#008ae8")
y = (str(y))
c.create_text(x0 + 10, y0, anchor = SW, text = (y, "%"))
c.create_text(x0 + 60, y1 + 5, anchor = N, text = "Catchment")
photo = ImageTk.PhotoImage(file =
"/Users/Name/Desktop/python3.4/water.png")
c.create_image(10, 10, image = photo, anchor = NW)
mainloop()
但是，当我将它放在我的主应用程序中时（连同我的其余代码），图像不会显示。图形和画布显示，而不是 water.png 图像。没有错误日志或任何东西。当我把它放在我的应用程序中时，我所做的唯一改变是在这一行中添加“自我”。（我当然删除了'mainloop（）'）。
c = Canvas(self, width = 200, height = 235, relief = "sunken", borderwidth = 2)
任何建议将不胜感激。
