This is project to demo how to use these two Python libraries MSS [Ref 1] and PYAUTOGUI [Ref 2] in

1. Standalone Applications (UC1): Take a screen shot, resize and display it

• screen_mss.py (hit any key to terminate)
• screen_pag.py (hit any key to terminate)

2. Client-server Applications (UC2): Take screenshots, transfer them from client to server and display by the server

• server.py
• client_mss.py (esc to terminate)
• client_pag.py (esc to terminate)

3. Web Applications (UC3): Take screenshots by webservers, and delivery to a web browser on demand.

• app_mss.py
• app_pag.py
• http://host:port/ (url @ web browser)

This project also uses the concepts and skills of another [Ref 3]
"Live Video Streaming with Python", and proves that

• live video and
• screenshots

are only different types of contents which are independent of the technologies
used to process them.

Please refer that project about the details for

1. Client-Server programming with socket
2. Data Transfer with Protocol (simple header-body structure)
3. Multi-thread (server side connection handling)
4. Live Video with OpenCV (video capture and show at different sides)
5. Asynchronous Programming (client side key-event handling)
6. Web version with Flask (minimum code and html)
