Hi,
I am looking for some information on the internal structure of a JPEG file. I was playing with a handful of bits in a JPEG file as part of a steganagraphy experiment and I saw something remarkable. I am able to cause a lateral shifting in the file. It is as if someone has torn the right quarter of the picture and pasted it on the extreme left. I was certainly expecting loss of clarity in the picture, but seeing such a remarkable phenomenon has left me completely dumbstruck. Any suggestions what might be causing this?
Thanks,
Bhat
