        public SubImageInputStream​(javax.imageio.stream.ImageInputStream pStream,
                           long pLength)
                    throws java.io.IOException
        Creates a ImageInputStream, reading up to a maximum number of bytes from the underlying stream.
        Parameters:
        pStream - the underlying stream
        pLength - the maximum length to read from the stream. Note that pStream may contain less than this maximum number of bytes.
        Throws:
        java.io.IOException - if pStream's position can't be determined.
        java.lang.IllegalArgumentException - if pStream == null or pLength < 0
