Dear Stefano,
Use PixelGrabber to get an array of bytes (for IndexColorModel) or integers
(standard RGB); send the array, and use MemoryImageSource to re-assemble on
the other end. Image is not a serializable class - I can't imagine why.
If you must use object streams, wrap the pixels and red, green, blue, alpha
in a class of your own that is declared serializable. Another way to do it
is to paint the image on a Canvas (or other component) and serialize that,
since all components are serializable.
Hope this helps,
Peter Johnson
