So i am using python 3 and got confused why the image doesnt show up in text widget after excuted the following code:

from tkinter import *
import fitz

root=Tk()
filenew=fitz.open(r'C:\Users\azoka\Desktop\Python\b.pdf')

text_1=Text(root,width=100,height=100,bg='gray').pack(side=LEFT,expand=FALSE)

def Show(): 
   pix =filenew.getPagePixmap(0)   # 0 is page number
   pix1=fitz.Pixmap(pix,0)
   img =pix1.getImageData("ppm")
   timg=PhotoImage(data=img)
   frame=[]
   frame.append(timg)
   text_1.image_create(END,image=timg)

Shower=Button(win1,text='show',bg='navy',fg='light cyan',width=5,height=1,command=Show)
Shower.place(x=1000,y=360)

root.mainloop()

The image just dont show up after clicked the button but it doesnt show any code error,I am new to python and cant figure out. I want my img be shown without altering the Show()function.

-Appreciate for helpful answers!-

  • The variable `frame` is discarded and garbage collected after the function ends so `timg` is also garbage collected. Try defining `frame = []` outside of the function or add `text_1.tk_img = timg` – TheLizzard May 06 '21 at 17:28

  • @BryanOakley I think you are right but OP tried putting the `PhotoImage`s in a list but the list goes out of scope as well. – TheLizzard May 06 '21 at 17:48
  • Its working now! Now I understand the mistakes, thanks for the replies. @TheLizzard – Lee hua Wei May 07 '21 at 02:02
