How to Display tkinter image without transparent background

Question

Having trouble displaying image (PIL/tkinter). Image displays but with transparent background.

import tkinter as tk
from PIL import Image, ImageTk

path = "zzz.png"

root = tk.Tk()
img = ImageTk.PhotoImage(Image.open(path))
panel = tk.Label(root, image = img)
panel.pack(side = "bottom", fill = "both", expand = "yes")

root.mainloop()

I want background to be opaque.

I noticed that this is only an issue in a gnome3 desktop; where the program launches from a gnome-terminal.

Another update. Only issue when running desktop remotely using xrdp. Following link shows similar issue:
https://github.com/neutrinolabs/xrdp/issues/1906 However; I am not able to get xrdb working in 24bit color depth mode.

screenshot of program's output displayed on an xrdp desktop. image that may be used in program.

How to Display tkinter image without transparent background

Try this without using PIL namespace.

• Add this wm_attributes before mainlioop().

Snippet:

import tkinter as tk

root = tk.Tk()

path = "p2.png"

photo = tk.PhotoImage(file=path)
tk.Label(root,image=photo,bg='grey').pack(side = "bottom", fill = "both", expand = "yes")

#your other label or button or ...
root.wm_attributes("-transparentcolor", 'grey')
root.mainloop()
