public abstract class PDFXObject
Abstract base class of PDF XObjects. A derivative of the PDF Object, is a PDF Stream that has not only a dictionary but a stream of image data. The dictionary just provides information like the stream length. This outputs the image dictionary and the image data. This is used as a reference for inserting the same image in the document in another place.
