41 * A JPEG file consists of a sequence of each of which has an
42 * associated {@link PelJpegMarker marker} and some content. This
43 * class represents the content, and this basic type is just a simple
44 * holder of such content, represented by a {@link PelDataWindow}
45 * object. The {@link PelExif} class is an example of more
46 * specialized JPEG content.

68 * Return the bytes of the content.
70 * @return string bytes representing this JPEG content. These bytes
71 * will match the bytes given to {@link __construct the
