Java Programming

Hi all, I'm a new user!
I'm working with As400 and java using jtopen.
With this code:

PrintObjectTransformedInputStream is = spoolFile.getTransformedInputStream(printParms);            
BufferedInputStream bufIn = new BufferedInputStream(is);                        
BufferedOutputStream bufOut = new BufferedOutputStream(new FileOutputStream("c:/x.tif"));
            
int c;
while ((c = bufIn.read()) != -1) {
     bufOut.write(c);
}

bufIn.close();
bufOut.close();

I'm getting a tiff stream and then write it to a file. The tiff stream is in Big endian format, but I need a tiff in Little endian format.
How can I convert the stream from Big endian to Little endian?
Thanks
