Python ImageTK Module

We already know that tkinter is a package used for building Graphical user interface applications in Python.Now ImageTk module is used with graphical interface functions of the Tkinter package.
So far with Pillow library we have loaded the various formats of image,manipulated the image and finally displayed with open and show methods.If it is required to display the image in tkinter window then ImageTk is helpful..
The ImageTk module contains two classes namely PhotoImage and BitmapImage

PhotoImage class
Creates photo image that is compatible with Tkinter which can be used everywhere Tkinter expects an image object.

import Tkinter
top = Tkinter.Tk()
# Code to add widgets will go here...
top.mainloop()

import Tkinter
from PIL import ImageColor
from PIL import ImageTk
im = Image.open('flower1.jpg') 
top = Tkinter.Tk()
# Convert the Image object into a TkPhoto object
pimage_obj = ImageTk.PhotoImage(im)
Tkinter.Label(top, image=pimage_obj).pack() 
# Start the GUI
top.mainloop()
