* implementation of this interface for use by the Image I/O API.
*
* <p> Unlike a standard <code>OutputStream</code>, ImageOutputStream
* extends its counterpart, <code>ImageInputStream</code>. Thus it is
* possible to read from the stream as it is being written. The same
* seek and flush positions apply to both reading and writing, although
* the semantics for dealing with a non-zero bit offset before a byte-aligned
* write are necessarily different from the semantics for dealing with
* a non-zero bit offset before a byte-aligned read. When reading bytes,
* any bit offset is set to 0 before the read; when writing bytes, a
* non-zero bit offset causes the remaining bits in the byte to be written
* as 0s. The byte-aligned write then starts at the next byte position.
