com.lightcrafts.utils.bytebuffer.ArrayByteBuffer
An ArrayByteBuffer is-an {@link LCByteBuffer} that uses eitheran ordinary byte array or a {@link ByteBuffer} for its backing-store.
This class is used to adapt a {@link ByteBuffer} to an {@link LCByteBuffer}. @author Paul J. Lucas [paul@lightcrafts.com]

                // offsets are relative to its start, so this makes it easy to
                // read it: just extract the block and treat it like a TIFF
                // file.
                //
                m_tiffBlock =
                    new ArrayByteBuffer( m_buf.getBytes( blockSize ) );
                m_tiffMetadataReader =
                    new TIFFMetadataReader( m_imageInfo, m_tiffBlock );
                m_tiffMetadataReader.readHeader();
