eanicom has asked for the wisdom of the Perl Monks concerning the following question:

Hello Perl Masters, I'm looking for a guide in being able to decode a png image file. I'm not looking for someone to hand the answer over to me but at least to guide me. Is there a perl module I can start to use to analyze and decode a png image file? There is a hidden message in the PNG image file that I would like to learn to decode.

    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
