Can SpirePDF extract pdf documents in a portfolio

[kensmith38]

I am using FreeSpire, but I would likely purchase the developer license if SpirePDf has ability to extract pdf documents (and possibly Word.docs, images, etc) that are embedded in a portfolio pdf document.
Does spirePDf have that capability?

Hello,

Thanks for your inquiry!

Our Spire.PDF can extract PDF documents, Word. Docs, images, etc in a portfolio, please refer to the following code to achieve it. I also attached my input file for your reference.

Code: Select all

//add portfolio
            string inputfile1 = @"E:\testdoc\sample2.pdf";
            string inputfile2 = @"E:\testdoc\doc2.docx";
            string inputfile3 = @"E:\testdoc\test.png";

            PdfDocument pdf = new PdfDocument();
            pdf.Collection.AddFile(inputfile1);
            pdf.Collection.AddFile(inputfile2);
            pdf.Collection.AddFile(inputfile3);

            pdf.SaveToFile("portfolio.pdf", FileFormat.PDF);
            pdf.Dispose();

//extrct portfolio
            PdfDocument newpdf = new PdfDocument();
            newpdf.LoadFromFile("portfolio.pdf");

            foreach (PdfAttachment attachment in newpdf.Attachments)
            {
                string filename = attachment.FileName;
                File.WriteAllBytes(filename,attachment.Data);
            }
            newpdf.Dispose();

I would like to thank you, Annika, for all of your help; you went above and beyond the amount of assistance that I expected.
I have confirmed your latest code recommendation (look for annotation attachments). You duplicated my scenario (creating a PDF from an Outlook email which had attachments in the email) and you provided the exact code snippet to count those annotation attachments. We should consider this issue to be resolved.
Thanks for all of your help.
Sincerely,
Ken Smith
