Python:Tkinter TclError:无法调用"image"命令 [英] Python: Tkinter TclError: can't invoke "image" command

问题描述

前言:我目前已经尝试了大多数事情，并且在stackoverflow上对此问题提出的问题很少，我似乎无法解决这个问题，所以即时通讯需要一些帮助

preface: I have currently tried most things and there are few qusestions asked on stackoverflow on this question and i cant seem to wrap my head around it so im going to need some help

应用程序 :该程序的目的是为椭圆和图片设置动画，该椭圆可以正常工作，但是图片很费力，您可以删除图片或 alien2 ，该程序应该可以正常运行.

application: the purpose of this program is to animate an oval and a picture, the oval works fine, but the picture is struggling, you could remove the image or alien2 and the program should run fine.

我知道代码不是很漂亮，但是它是一个测试环境，并且如上所述，所有内容都可以正常工作，但是当使用图像而不是椭圆形时，它会中断，这不会有太大的不同.预先感谢！

I know the code is not beautiful, but it's a test environment and as mentioned everything should work flawless, but it breaks when an image is used instead of an oval which should not make a big difference. Thanks in advance!

当我删除应用程序未得到 TclError <时，在 PhotoImage()中分配 master 时出现了问题/p>

新问题

turns out the problem turned up when assigning master inside PhotoImage(), when i removed that the application did not get the TclError

我对代码所做的更改来自于此:

the changes i made to the code were from this:

        self.cardPath = Image.open('bubble.png')
        self.resCard = cardPath.resize((100,100))
        self.CardVar = ImageTk.PhotoImage(resCard,master=root)

对此:

    self.cardPath = Image.open('bubble.png')
    self.resCard = cardPath.resize((100,100))
    self.CardVar = ImageTk.PhotoImage(resCard)

推荐答案

一段时间后，我编辑了代码并使之工作.这是完整的代码

After a while i edited the code and made it work. here is the full code

from tkinter import *
import time
import PIL
from PIL import Image,ImageFilter
from PIL import ImageTk

class alien(object):
    def __init__(self):

    self.root = Tk()
    self.canvas = Canvas(self.root, width=400, height = 400)
    self.canvas.pack()

    CardVar = ImageTk.PhotoImage(file='bubble.png')
    self.alien1 = self.canvas.create_oval(20, 260, 120, 360, outline='white',fill='blue')
    self.alien2 = self.canvas.create_image((100,100),image=CardVar,anchor=CENTER)
    self.canvas.pack()
    self.root.after(0, self.animation)
    self.root.mainloop()


 def animation(self):
    track = 0
    while True:
        x = 5
        y = 0
        if track == 0:
           for i in range(0,51):
                time.sleep(0.025)
                self.canvas.move(self.alien1, x, y)
                self.canvas.move(self.alien2, x, y)
                self.canvas.update()
           track = 1
           print("check")

        else:
           for i in range(0,51):
                time.sleep(0.025)
                self.canvas.move(self.alien1, -x, y)
                self.canvas.move(self.alien2, -x, y)
                self.canvas.update()
           track = 0
        print(track)
alien()

问题

cardVar即使在同一文件夹中也始终无法找到正确的图像，因此我尝试执行cardVar.show()，并且显示了另一个位置较远的图像，因此似乎已将某些内容保存在其中我的记忆.所以我决定重启内核，一切顺利
