Kay [80]
The fax modem is used to send and receive fax messages by only having phone line (fax machine is not required). The scanned documents should be saved as digital file (image or PDF format) in order to be sent. So, in order to send a portion of a map you should first convert the map into digital file and than simply send it through the fax modem. The best way to convert it to a digital file is to use an optical character recognition (OCR).

Korvikt [17]

to create a simple notepad in Python using Tkinter. This notepad GUI will consist of various menu like file and edit, using which all functionalities like saving the file, opening a file, editing, cut and paste can be done.

Now for creating this notepad, Python 3 and Tkinter should already be installed in your system. You can download suitable python package as per system requirement. After you have successfully installed python you need to install Tkinter (a Python’s GUI package).

Use this command to install Tkinter :

pip install python-tk

import os  

from tkinter import *

 

# To get the space above for message  

from tkinter.messagebox import *

from tkinter.filedialog import *

self.__thisTextArea.grid(sticky = N + E + S + W)  

 

# To open new file  

self.__thisFileMenu.add_command(label = "New",  

                               command = self.__newFile)  

 

# To open a already existing file  

self.__thisFileMenu.add_command(label = "Open",  

                               command = self.__openFile)  

 

# To save current file  

self.__thisFileMenu.add_command(label = "Save",  

                               command = self.__saveFile)  

 

# To create a line in the dialog  

self.__thisFileMenu.add_separator()  

 

# To terminate  

self.__thisFileMenu.add_command(label = "Exit",  

                               command = self.__quitApplication)  

self.__thisMenuBar.add_cascade(label = "File",  

                              menu = self.__thisFileMenu)  

 

# To give a feature of cut  

self.__thisEditMenu.add_command(label = "Cut",  

                               command = self.__cut)  

 

# To give a feature of copy  

self.__thisEditMenu.add_command(label = "Copy",  

                               command = self.__copy)  

 

# To give a feature of paste  

self.__thisEditMenu.add_command(label = "Paste",  

                               command = self.__paste)  

 

# To give a feature of editing  

self.__thisMenuBar.add_cascade(label = "Edit",  

                              menu = self.__thisEditMenu)  

 

# To create a feature of description of the notepad  

self.__thisHelpMenu.add_command(label = "About Notepad",  

                               command = self.__showAbout)  

self.__thisMenuBar.add_cascade(label = "Help",  

                              menu = self.__thisHelpMenu)  

 

self.__root.config(menu = self.__thisMenuBar)  

 

self.__thisScrollBar.pack(side = RIGHT, fill = Y)  

 

# Scrollbar will adjust automatically  

# according to the content  

self.__thisScrollBar.config(command = self.__thisTextArea.yview)  

self.__thisTextArea.config(yscrollcommand = self.__thisScrollBar.set)  

With this code we will add the menu in the windows of our notepad and will add the things like copy, paste, save etc, to it.
