Python tkinter:
import tkinter as tk
from PIL import Image, ImageTk
from tkinter.filedialog import askopenfile
import PyPDF2 # to extract text from pdf
root = tk.Tk() # begining of our interface
root.mainloop() # end command of interface
# all elements we put between this 2 lines # root=tk.Tk() and root.mainloop() will apear
# inside our window object # to precise the dimention of our window
# object we create a variable called canvas
# then we divide the window to 3 imaginary
# column with Canvas.grid() to place our #elements precisely
canvas = tk.Canvas(root, width=600, height=300)
Canvas.grid(columnspan=3)
# now To place an image we create a new
# variable : logo logo = Image.open(‘file.png’) # then we convert this pillow image to # tkinter image by typing this :
logo= ImageTk.PhotoImage(logo)
# then we place the image inside a label # widget to apear :
logo_label = tk.Label(image=logo)
logo_label.image=logo
logo_label.grid(column=1, row=0)
# to add instruction text :
instructions = tk.Label(root, text=“Select a PDF file on your computer”, font=“Raleway”)
instructions.grid(columnspan=3 , column=0,row=1)
# to add a browse button that change its caption : browse_text = tk.StringVar()
browse_btn = tk.Button(root,textvariable =browse_text, command=lambda:open_file(), font=“Raleway” ,bg=“#20bebe”,fg=“white”, height=2, width=15)
browse_text.set(“Browse”)
browse_btn.grid(column=1,row=2)
# then we add a fuction in the beginning that will
# be lunched when we push the button due to the
# command =lambda:open_file()
# to open browser and chose a file on pc
# need now to import askopenfile from # tkinter.filedialog
def open_file():
browse_text.set(“loading…”) # change caption # butn to loading
file=askopenfile(parent=root,mode=‘rb’,title=“choose a file”,filetype=[(“Pdf file”, “*.pdf”)])
if file: # if file is selected
read_pdf=PyPDF2.PdfFileReader(file) # read file and store it in vars # read_pdf
page = read_pdf.getPage(0)
page_content = page.extractText()
# now writing the content in a text box :
text_box = tk.Text(root,height=10 ,width=50, padx=15, pady=15)
text_box.insert(1.0, page_content)
text_box.grid(column=1, row=3)
# at the end reset caption of btn to browse:
browse_text.set(“Browse”)
