Hiee,

I have written a similar code for encoding data ...I'm not able to retrieve the same text while recovering, please help me out in d recovery of text from LSB. Actually while encoding I'm converting it to Double and then saving at the LSB of the image. so while retrieving I'm not getting the same text/ASCII value.

Thanks in Advance
Thomas
