Thanks,
As per your suggestion using annotation I was able to extract the name of
the embedded file however the contents of that file could not be extracted
Please refer to the code below.
var originalDocument = PDDocument.load(_PdfFile);
var originalCatalog = originalDocument.getDocumentCatalog();
java.util.List sourceDocumentPages = originalCatalog.getAllPages();
var newDocument = new PDDocument();
//number of pages in pdf file = 2
int[] PageNumbers = { 1, 2 };
foreach (var pageNumber in PageNumbers)
{
// Page numbers are 1-based, but PDPages are contained in a zero-based
array:
int pageIndex = pageNumber - 1;
PDPage pdpage = new PDPage();
try
{
pdpage = (PDPage)sourceDocumentPages.get(pageIndex);
List anno = pdpage.getAnnotations();
If(anno.size() > 0)
{
PDAnnotationFileAttachment pafa = (PDAnnotationFileAttachment)anno.get(0);
//FILENAME = GETCONTENTS()
string filename = pafa.getContents();
PDFileSpecification fs = pafa.getFile();
}
}
catch (Exception)
{ }
}
Can you help me one more time to extract and dump the embedded file in the
specified location?
