You can do this as follows for a portfolio loaded in a PdfDocument pdfDocument (Java version the OP edited a port to C# into his question body): PdfNameTree embeddedFilesTree = pdfDocument.getCatalog().getNameTree(PdfName.EmbeddedFiles)
To merge all pdf files from a PDF Portfolio to a normal pdf file you have to walk the name tree of EmbeddedFiles, retrieve the streams of all PDFs therein, and then merge all these PDFs. PdfMerger.Merge(embeddedPdfDocument, 1, embeddedPdfDocument.GetNumberOfPages()) PdfDocument embeddedPdfDocument = new PdfDocument(embeddedReader) PdfReader embeddedReader = new PdfReader(sourceFactory.CreateSource(pdfStream.GetBytes()), new ReaderProperties()) RandomAccessSourceFactory sourceFactory = new RandomAccessSourceFactory() įoreach (PdfStream pdfStream in embeddedPdfs) PdfMerger pdfMerger = new PdfMerger(flatPdfDocument) PdfDocument flatPdfDocument = new PdfDocument(pdfWriter)
PdfWriter pdfWriter = new PdfWriter("NPort_5000-flat.pdf", new WriterProperties().SetFullCompressionMode(true)) PdfName subtype = embeddedFileStream.GetAsName(PdfName.Subtype) PdfStream embeddedFileStream = embeddedFileDict.GetAsStream(PdfName.F) PdfDictionary embeddedFileDict = filespecDict.GetAsDictionary(PdfName.EF) PdfDictionary filespecDict = (PdfDictionary)pdfObject IDictionary embeddedFilesMap = embeddedFilesTree.GetNames() įoreach (PdfObject pdfObject in embeddedFilesMap.Values) Solution by mkl ported to C#: PdfNameTree embeddedFilesTree = pdfDocument.GetCatalog().GetNameTree(PdfName.EmbeddedFiles)

Instead of removing anything from the source document, I would like to know how to get the PdfDocument object(s) out of the PdfArray if possible. Remove the reference to the embedded file. Remove the description of the embedded file PdfArray namesArray = embeddedFiles.GetAsArray(PdfName.Names) PdfDictionary embeddedFiles = names.GetAsDictionary(PdfName.EmbeddedFiles) PdfDictionary names = root.GetAsDictionary(PdfName.Names) PdfDictionary root = pdfDoc.GetCatalog().GetPdfObject() Bitcoin widget template comes with simple bitcoin price widget and bitcoin price. With unencrypted wrapper document the files with custom encryption are added as embedded. When using non-standard encryption, the user is typically confronted with a non-working document without much information why. PdfDocument pdfDoc = new PdfDocument(new PdfReader(SRC), new PdfWriter(dest)) Since PDF 2.0, PDF portfolios are also used as the supporting technology for the unencrypted wrapper document concept.

So, here's part of the code from the linked example: protected void ManipulatePdf(String dest) I did not want to make you write the program for me.) By saying what I want to achieve, I simply wanted to make it easier for you guys to help me. Every non-pdf attachment should be ignored. In the end I would like to simply merge every pdf file contained in a portfolio into a single "normal" pdf file. I took this C# example and tried to get the attachments as a PdfDocument, but I couldn't figure out how to do it.
