how to return the exact value of an array that converted to image?

[Sahar Salah Aldeen]

Hi;
I am doing a research in images; in that i split the original image into shares by an algorithm that work fine; but the values of the pixels that it produces are larger than 256,so when i put them back in an image the java reduce the values to less than 256 and when i want to do the reverse of the algorithm i get the wrong values because of the reduction that done by java... what can i do?
please answer me.
thank you...
(sorry for my bad language).

Post the code you're using to dissect the image, and the code you're using to put it back together.
