in reply to Decoding a PNG image file

Do you know how the hidden message is encoded into the PNG image? Or do you have an algorithm for decoding it?

Don't trust the "ACME::*" modules that were suggested. They can only decode files they have encoded themselves and as Acme::Steganography::Image::Png says itself it is "extremely ineffective at hiding your secrets inside Png images".

A program should be light and agile, its subroutines connected like a string of pearls. The spirit and intent of the program should be retained throughout. There should be neither too little or too much, neither needless loops nor useless variables, neither lack of structure nor overwhelming rigidity." - The Tao of Programming, 4.1 - Geoffrey James
