Oh, ok. You can add keys using the PdfDictionary class. PoDoFo will take care of the Subtype entry in the annotation object for you already though.
A bit longer example below showing how to add different types to the
anotations directory.
PdfMemDocument doc("file.pdf");
// This object will hold your stream data
PdfObject* pStream = doc.GetObjects().CreateObject( "3D" );
pStream->AddKey( PdfName("Subtype"), PdfName("U3D") );
pStream->GetStream()->Set( pointer to your data, length of your data ); // the
here the data buffer. PoDoFo will do compression etc for you.
PdfPage* pPage = doc.CreatePage( PdfPage::CreateStandardPageSize( A4 ) );
PdfAnnotation* pAnnot = pPage->CreateAnnotation( ePdfAnnotation_3D );
pAnnot->GetObject()->GetDictionary().AddKey( PdfName("3DD"),
pStream->Reference() );

Dom
