Specified by:
  `startPageContent` in interface `IFDocumentHandler`
Returns:
  the IFPainter for the page content
Throws:
  `IFException` - if an error occurs while handling this event

#### endPageContent

    public void endPageContent()

#### startDocumentTrailer

    public void startDocumentTrailer()
                              throws IFException

Indicates the start of the document trailer. This method is called after the last page sequence. Extensions sent to the painter between `IFDocumentHandler.startDocumentTrailer()` and `IFDocumentHandler.endDocumentTrailer()` apply to the document as a whole and is used for document-level content that is only known after all pages have been rendered (like named destinations or the bookmark tree).

Specified by:
  `startDocumentTrailer` in interface `IFDocumentHandler`
Throws:
  `IFException` - if an error occurs while handling this event

#### endDocumentTrailer

    public void endDocumentTrailer()

#### endDocument

    public void endDocument()
                     throws IFException

Specified by:
  `endDocument` in interface `IFDocumentHandler`
Throws:
  `IFException` - if an error occurs while handling this event

#### handleExtensionObject

Handles an extension object. This can be a DOM document or any arbitrary object. If an implementation doesn't know how to handle a particular extension it is simply ignored.

Specified by:
  `handleExtensionObject` in interface `IFDocumentHandler`
Parameters:
  `extension` - the extension object
Throws:
  `IFException` - if an error occurs while handling this event
