Create a Sideshow application in Python

          Create an application for image slide show using python

In this article, we will create a slideshow application i.e we can see the next image without changing it manually or by clicking. 

Modules Required:

tkinter: It is used to create Graphical User Interface for the desktop application.

PIL: It is the image processing library used to work with images. Here we will use this module for creating thumbnails and to read the images to display them as label for the slide show.

Installation:

pip install Pillow

Note: The images that you are using should be in the same working directory where your python file is saved.

Code:

from tkinter import *

from PIL import Image, ImageTk

root = Tk()

root.title("Slide Show")

root.geometry("1000x600")

root.config(bg="blue4")

root.resizable(0, 0)

def start():                                                     

    global i, show

    if i >= (len(images)-1):

        i = 0

        slide_image.config(image = images[i])

    else:

        i = i + 1

        slide_image.configure(image = images[i])

    show = slide_image.after(2000 , start)

def stop():

    global show

    slide_image.after_cancel(show)

    

def resume():

    start()

            

# create thumbanials of all images  

img1 = Image.open('slide1.png')

img1.thumbnail((600, 650))      # 650 --> 550

img2 = Image.open('slide2.png')

img2.thumbnail((600, 650))

img3 = Image.open('slide3.png')

img3.thumbnail((600, 650))

img4 = Image.open('slide4.png')

img4.thumbnail((600, 650))

# open images to use with labels

image1 = ImageTk.PhotoImage(img1)

image2 = ImageTk.PhotoImage(img2)

image3 = ImageTk.PhotoImage(img3)

image4 = ImageTk.PhotoImage(img4)

# create list of images

images = [image1, image2, image3, image4]

# configure the image to the Label 

i = 0

slide_image = Label(root , image=images[i])

slide_image.pack(pady=50)

# create buttons

btn1 = Button(root, text="Start", bg='black', fg='gold', width=6, font=('ariel 20 bold'), relief=GROOVE, command=start)

btn1.pack(side=LEFT, padx=60, pady=50)

btn2 = Button(root, text="Pause/Stop", bg='black', fg='gold', width=10, font=('ariel 20 bold'), relief=GROOVE, command=stop)

btn2.pack(side=LEFT, padx=60, pady=50)

btn3 = Button(root, text="Resume", bg='black', fg='gold', width=8, font=('ariel 20 bold'), relief=GROOVE, command=resume)

btn3.pack(side=LEFT, padx=60, pady=50)

btn4 = Button(root, text="Exit", bg='black', fg='gold', width=6, font=('ariel 20 bold'), relief=GROOVE, command=root.destroy)

btn4.pack(side=LEFT, padx=30, pady=50)

root.mainloop()
