Working with Portfolio in PDF

How to Create a PDF Portfolio

Aspose.PDF allows creating PDF Portfolio documents using the Document class. Add a file into a Document.Collection object after getting it with the FileSpecification class. When the files have been added, use the Document class’ Save method to save the portfolio document.

The following example uses a Microsoft Excel File, a Word document and an image file to create a PDF Portfolio.

The code below results in the following portfolio.

The following code snippet also work with Aspose.PDF.Drawing library.

PDF Portfolio created with Aspose.PDF

// For complete examples and data files, visit https://github.com/aspose-pdf/Aspose.PDF-for-.NET
private static void CreatePortfolio()
{
    // The path to the documents directory
    var dataDir = RunExamples.GetDataDir_AsposePdf_TechnicalArticles();

    // Create PDF document
    using (var document = new Aspose.Pdf.Document())
    {
        // Instantiate document Collection object
        document.Collection = new Aspose.Pdf.Collection();

        // Get Files to add to Portfolio
        var excel = new Aspose.Pdf.FileSpecification(dataDir + "HelloWorld.xlsx");
        var word = new Aspose.Pdf.FileSpecification(dataDir + "HelloWorld.docx");
        var image = new Aspose.Pdf.FileSpecification(dataDir + "aspose-logo.jpg");

        // Provide description of the files
        excel.Description = "Excel File";
        word.Description = "Word File";
        image.Description = "Image File";

        // Add files to document collection
        document.Collection.Add(excel);
        document.Collection.Add(word);
        document.Collection.Add(image);

        // Save PDF document
        document.Save(dataDir + "CreatePortfolio_out.pdf");
    }
}

Extract files from PDF Portfolio

PDF Portfolios allow you to bring together content from a variety of sources (for example, PDF, Word, Excel, JPEG files) into one unified container. The original files retain their individual identities but are assembled into a PDF Portfolio file. Users can open, read, edit, and format each component file independently of the other component files.

Aspose.PDF allows the creation of PDF Portfolio documents using Document class. It also offers the capability to extract files from PDF portfolio.

The following code snippet shows you the steps to extract files from PDF portfolio.

// For complete examples and data files, visit https://github.com/aspose-pdf/Aspose.PDF-for-.NET
private static void ExtractPortfolioFiles()
{
    // The path to the documents directory
    var dataDir = RunExamples.GetDataDir_AsposePdf_TechnicalArticles();

    // Open PDF document
    using (var document = new Aspose.Pdf.Document(dataDir + "PDFPortfolio.pdf"))
    {
        // Get collection of embedded files
        Aspose.Pdf.EmbeddedFileCollection embeddedFiles = document.EmbeddedFiles;
        // Iterate through individual file of Portfolio
        foreach (Aspose.Pdf.FileSpecification fileSpecification in embeddedFiles)
        {
            // Get the attachment and write to file or stream
            byte[] fileContent = new byte[fileSpecification.Contents.Length];
            fileSpecification.Contents.Read(fileContent, 0, fileContent.Length);
            string filename = Path.GetFileName(fileSpecification.Name);
            // Save the extracted file to some location
            using (FileStream fileStream = new FileStream(dataDir + filename + "_out", FileMode.Create))
            {
                fileStream.Write(fileContent, 0, fileContent.Length);
            }
        }
    }
}
