Public Methods

public void close ()

Frees the native memory of the object. This can be explicity called to control the deallocation of native memory and avoid situations where the garbage collector does not free the object in a timely manner.

Throws
PDFNetException

public void destroy ()

Frees the native memory of the object. This can be explicity called to control the deallocation of native memory and avoid situations where the garbage collector does not free the object in a timely manner.

Throws
PDFNetException

public Obj getContainingStm ()

Get the containing Stream object.

Note: this method only applies to content items with type e_MCR.

Returns
  • The stream object that contains the marked-content sequence. The function will return a non-NULL object only if the marked-content sequence resides in a content stream other than the content stream for the page (e.g. in a form XObject).
Throws
PDFNetException

public int getMCID ()

Get the marked-content identifier.

Note: this method only applies to content items with types e_MCR or e_MCID.

Returns
  • mcid (marked-content identifier).
Throws
PDFNetException

public Page getPage ()

The page on which the marked content is drawn, whether directly as part of page content or indirectly by being in a Form XObject or annotation drawn on that page.

Returns
  • the page
Throws
PDFNetException

public SElement getParent ()

Find the parent structure element.

Returns
  • parent
Throws
PDFNetException

public Obj getRefObj ()

Get the referenced object.

Note: this method only applies to content items with type e_OBJR.

Returns
  • The referenced object.
Throws
PDFNetException

public Obj getSDFObj ()

Get the SDFObj.

Returns
  • Pointer to the underlying SDF/Cos object.
Throws
PDFNetException

public Obj getStmOwner ()

Get the Stream owner.

Note: this method only applies to content items with type e_MCR.

Returns
  • NULL or the PDF object owning the stream returned by GetContainingStm() (e.g. the annotation to which an appearance stream belongs).
Throws
PDFNetException

public int getType ()

Get the ContentItem type

Returns
  • the ContentItem type.
Throws
PDFNetException
