Work With Attachments and Portfolio Documents

PDF Xpress™ supports working with Attachments and Portfolio Documents.

To determine if a PDF document is a Portfolio, check the IsPortfolio property.

If the document is a Portfolio, if rasterized then what’s rendered is the Portfolio’s Cover Sheet. To access the contents of the portfolio you need to get the Document’s attachments.

The following is an example in which a PDF document is opened, a determination is made as to whether it's a portfolio, and the attachments of the document are accessed. You can then build a UI to show the various properties of the attachments, open the attachment’s data, and modify it.

C#	Copy Code
using Accusoft.PdfXpressSdk; using System.Drawing; namespace PortfolioAndAttachments { class Program { static void Main(string[] args) { using (PdfXpress pdf = new PdfXpress()) { pdf.Initialize(); using (Document doc = new Document(pdf, "portfolio.pdf")) { if (doc.IsPortfolio) { int attachmentCount = doc.GetAttachmentCount(); for (int attachmentIndex = 0; attachmentIndex < attachmentCount; attachmentIndex++) { using (PdfDocumentAttachment attachment = doc.GetAttachment(attachmentIndex)) { //access the attachment data as you please here... } } } } } } } }

                {
                    if (doc.IsPortfolio)
                    {
                        int attachmentCount = doc.GetAttachmentCount();
                        for (int attachmentIndex = 0; attachmentIndex < attachmentCount; attachmentIndex++)
                        {
