I would like to write a program which would be capable of creating and
encoding 2D barcodes (a student project, but a serious one).
I need to figure out the principles of information encoding into 2D barcodes.
I've searched all over the web and could find only short descriptions and images.
I really am not intending to cheat, and thus I am not asking for source codes and
somebody to do my work for me. I simply would like to be referred to some really
valuable and informative sources like articles, manuals, tutorials etc.
designed for programmers explaining the key points of 2D barcode development.
The major interest is in PDF417, Aztec Code, QR Code, Maxi Code and Data Matrix.
Any help will be sincerely appreciated.
Thank you in advance.
