tkinter 不打开图像

Question

请先看代码:

from tkinter import*
import time 
import random 
class Game:
def __init__(self):
    self.tk = Tk()
    self.tk.title("Mr Stickman races for the exit")
    self.tk.resizable(0, 0)
    self.tk.wm_attributes("-topmost", 1)
    self.canvas = Canvas(self.tk, width=500, height=500, highlightthickness= 0)
    self.canvas,Pack()
    self.tk.update()
    self.canvas_height = 500
    self.canvas_width = 500
    self.bg = PhotoImage(file="background1.gif")
    w = self.bg.width()
    h = self.bg.height()
    for x in range(0, 5):
        for y in range (0, 5):
            self.canvas.create_image(x * w, y * h, Image= self.bg, anchor="nw")
    self.sprites = []
    self.running = True


def mainloop(self):
while 1:
    if self.running == True:
        for sprite in self.sprites:
            sprite.move()
    self.tk.update_idletasks()
    self.tk.update()
    time.sleep(0.01)

g = Game()
g.mainloop()

当我运行它时，它显示：

_tkinter.TclError: couldn't open "background1.gif": no such file or directory

我也尝试过这种方式并得到了这个错误：

        self.bg = PhotoImage(file="C:\Users\Sajjad\Documents\python")

我把文件放在 excat 位置但得到了这个：

_tkinter.TclError: couldn't open "C:\Users\Sajjad\Documents\python": permission denied

我该怎么办？

Answer 1

你应该考虑多方面的事情：

1- Select 并正确找到图像地址 - 在我的例子中，我将图像和脚本放在同一个文件夹中

file=sys.path[0] + "/imageName.imageExt"

2- 替换

Image=self.bg

和

image=self.bg

3- 使用 place、pack 或 grid 将您的 canvas 放入应用程序 window 中；像这样：

self.canvas.place(x=0,y=0)

或您的情况更好：

self.canvas.pack()

4- 注意缩进块

from tkinter import*
import time
import sys


class Game:
    def __init__(self):
        self.tk = Tk()
        self.tk.title("Mr Stickman races for the exit")
        self.tk.resizable(0, 0)
        self.tk.wm_attributes("-topmost", 1)
        self.canvas = Canvas(self.tk, width=500,
                             height=500, highlightthickness=0)
        self.canvas, Pack()
        self.tk.update()
        self.canvas_height = 500
        self.canvas_width = 500

        # ***CHANGE "/back.png" WITH YOUR IMAGE; THIS IS JUST FOR TEST***
        self.bg = PhotoImage(file=sys.path[0] + "/back.png")  # HERE sys.path
        w = self.bg.width()
        h = self.bg.height()
        for x in range(0, 5):
            for y in range(0, 5):
                self.canvas.create_image(
                    x * w, y * h, image=self.bg, anchor="nw")  # HERE Image -> image
                self.canvas.pack()  # HERE
        self.sprites = []
        self.running = True

    def mainloop(self):
        while 1:
            if self.running == True:
                for sprite in self.sprites:
                    sprite.move()
            self.tk.update_idletasks()
            self.tk.update()
            time.sleep(0.01)


g = Game()
g.mainloop()

这是我在图形软件中绘制的“back.png”图像：
