Some solutions were suggested there, but you didn't indicate why you though they weren't useful to you. Just posting the question again and again won't help you unless you tell us what's wrong with those solutions. We're all trying to help people here, but can only do so if these people really want to be helped, that is they provide enough information for us to be able to help them.

Reply from Rafael (sent by e-mail): In the others news my problem was a bitmap stream over network .. I solved the problem using bitmaps diference .. In this case, I dont have a bitmap to compare, so, I have to use a compact algorithm. JPG and PNG are lossy algorithms that i can?t use .. i have to use a lossless algorithm ... Sorry if I don?t explain my question because my english is not very good ..
