ObjectiveC Syntax

 function Leadtools.Dicom.DicomDataSet.GetEncapsulatedDocument(DicomElement,Boolean,Stream,DicomEncapsulatedDocument,DicomCodeSequenceItem)( 
   element ,

public:
void GetEncapsulatedDocument( 
   DicomElement^ element,
   bool child,
   Stream^ stream,
   DicomEncapsulatedDocument^ encapsulatedDocument,
   DicomCodeSequenceItem^ conceptNameCodeSequence
)

Parameters

element: A DicomElement in the data set.
child: true to retrieve the encapsulated document as a child of element., false to retrieve the encapsulated document on the same level as element.
stream: The stream that will contain the encapsulated document.
encapsulatedDocument: The encapsulated document module attributes
conceptNameCodeSequence: The concept name code sequence attributes

Remarks

This feature is available in version 16 or higher.

The members of the DicomEncapsulatedDocument class and the DicomCodeSequenceItem class together represent the set of attributes contained in the "Encapsulated Document Module Attributes”. The Encapsulated Information Object Definition (IOD) describes one of the following file types that has been encapsulated within a DICOM information object:

PDF document
CDA document

For more information, refer to Part 3 of the DICOM standard.

The encapsulatedDocument class corresponds to the Encapsulated Document Module Attributes described in part 3 of the DICOM specification. To retrieve the Concept Name Code Sequence element (0040,A043) pass a conceptNameCodeSequence object.

stream is a stream that will contain the encapsulated document after it is extracted.
