Encipher/Encode images into text files

File Information

Description

"Is it possible to save an image as a text file and then reproduce the image from the RGB values (reading in the order from left to right and top to bottom) using an image reader?
I am thinking of producing a camera that saves text files instead of jpgs. The images will then be reproduced by using a converter."

This is the email i got from someone called John Aidiniantz from AMW SECURITY,LONDON.
And this inspired me to make this program.

The function 'image2text' enciphers or encodes an image into a text file.

The original image can then be retrieved back from this text file by using the function 'text2image'.

Screenshot explains the complete procedure.

25 Jan 2007	Akash Malhotra	This idea can be used in analysis of satellite images. Good work!
