[update] processing steganography refined

Hi guys I refined my sketch for steganography with processing.
New features:
-hide text not an image
-uses the 2 rightmost bits of each color channel with a total of 6 bits for each pixel
-can hide really long messages (such as Dante's divine comedy or the italian costitution)
The code is too long for posting it here so I'll link you a zip with all files.
Inside you'll find 2 version of the code one more commented and easier to understand and another maybe harder to understand but faster in executing.
Here is the code: link.
I hope you enjoy the code, if you have any question comment  or send me an email to damianoandre@gmail.com
Bye, Dami
