Displaying image using python

[Chau]

I have read somewhere that tkinter can be used to display an image on the screen, which is what I would like to do. I have loaded python but I cannot seem to find any recent reference to tkinter in the forum.

How can I load/install tkinter in my piCore 9.x?

Hi Rich

Thanks for your reply. I actually had installed tk but overlooked the difference between Tkinter and tkinter 

I have installed Xorg too since I expect to need it when using Tkinter to display an image. And maybe you can give me a hint on that part too:

Currently I'm just trying to do some basic stuff with Tkinter:

Code: [Select]

from Tkinter import *
root = Tk()

And this is where my next issue arises:

Code: [Select]

_tkinter.TclError: no display name and no $DISPLAY environment variable
Calling env in the console shows indeed no DISPLAY variable.

How is Tk connected to the monitor? I thought this was where Xorg came into play 

I'm accessing the PI directly and not through SSH or similar.
