/**
 * This class allows you to write/print into a PDFStream. Several methods are
 * available to specify the content of a page, image. This class performs some
 * error checking, while writing the stream.
 * <p>
 * The stream allows to write dictionary entries. The /Length entry is written
 * automatically, referencing an object which will also be written just after
 * the stream is closed and the length is calculated.
