HOW TO: Extract an encapsulated PDF document from a DICOM dataset file using C

#define IMAGE_PATH _T("C:\\Users\\Public\\Documents\\LEADTOOLS Images\\")
#define INPUT_DICOM_FILE IMAGE_PATH _T("Encapsulated.dcm")
#define OUTPUT_DOCUMENT_FILE IMAGE_PATH _T("Output.pdf")

// Declare a DICOM dataset handle, encapsulatedDocument, and conceptNameCodeSequence
HDICOMDS hDS = NULL;
DICOMENCAPSULATEDDOCUMENT encapsulatedDocument = { 0 };
DICOMCODESEQUENCEITEM conceptNameCodeSequence = { 0 };
pDICOMELEMENT pElement = NULL;

// Start the DICOM engine
L_DicomStartUp();

// Open the existing DICOM Dataset
hDS = L_DicomCreateDS(NULL);
L_DicomLoadDS(hDS, INPUT_DICOM_FILE, 0);

// Find the encapsulated document element
pElement = L_DicomFindFirstElement(hDS, NULL, TAG_ENCAPSULATED_DOCUMENT, L_TRUE);

// Retrieve the encapsulated document container to a file and metadata to
// encapsulated document and code sequence item structures
L_DicomGetEncapsulatedDocument(hDS, pElement, L_FALSE, OUTPUT_DOCUMENT_FILE,
   &encapsulatedDocument, &conceptNameCodeSequence);

// Cleanup
L_DicomFreeDS(hDS);
L_DicomShutDown();
