how do I create a full screen window with TkInter

[Jon Schull]

What would I add to this snippet to ensure to have the image being
displayed be all we see? (no titlebar, full size, etc.)

class UI(Label):

    def __init__(self, master, im):

        if im.mode == "1":
            # bitmap image
            self.image = ImageTk.BitmapImage(im, foreground="white")
            Label.__init__(self, master, image=self.image, bg="black",
bd=0)

        else:
            # photo image
            self.image = ImageTk.PhotoImage(im)
            Label.__init__(self, master, image=self.image, bd=0)

import sys
root=Tk()
filename=r'c:\temp\capture5.jpg'
im=Image.open(filename)
UI(root,im).pack()
root.mainloop()
