PdfExternalObject Class

An external object (commonly called an XObject) is a graphics object whose contents are defined by a self-contained stream, separate from the content stream in which it is used. There are three types of external objects:

  • An image XObject (8.9.5, "Image Dictionaries") represents a sampled visual image such as a photograph.
  • A form XObject (8.10, "Form XObjects") is a self-contained description of an arbitrary sequence of graphics objects.
  • A PostScript XObject (8.8.2, "PostScript XObjects") contains a fragment of code expressed in the PostScript page description language. PostScript XObjects should not be used.
