Why is image not showing up-CodePudding

Tried to display an image on a canvas but it won't show up

import tkinter

class ROOT():
    def __init__(self,root):
        root.geometry("500x500")
        self.canvas=tkinter.Canvas(root,width=500,height=500,bg="white")
        self.canvas.pack()

        self.photoimage=tkinter.PhotoImage(file="Untitled.png")#test image
        self.image=self.canvas.create_image((0,0),image=self.photoimage,anchor="nw")

def main():
    root=tkinter.Tk()
    ROOT(root)
    root.mainloop()

if __name__=="__main__":main()

I am using python 3.10.4 and have no clue why it isn't working, can somebody explain why

Also sorry for bad English

CodePudding user response：

You're supposed to pass two arguments to create_image, instead of a tuple. Also, you need to keep the variable, instead of letting it be garbage collected:

import tkinter

class ROOT():
    def __init__(self,root):
        root.geometry("500x500")
        self.canvas=tkinter.Canvas(root,width=500,height=500,bg="white")
        self.canvas.pack()

        self.photoimage=tkinter.PhotoImage(file="Untitled.png")#test image
        self.image=self.canvas.create_image(0,0,image=self.photoimage,anchor="nw")

def main():
    root=tkinter.Tk()
    root_class=ROOT(root)
    root.mainloop()

if __name__=="__main__":main()
