Embedding Files

The DynamicPDF Core Suite allows embedding any file type in a PDF document as an attachment.

Use the EmbeddedFile class to attach a file to a PDF document. To embed a file you use a Document class instance's EmbeddedFiles property to Add a file.

The Document class has an EmbeddedFiles property that consists of an b. You add an EmbeddedFile instance to this list using its Add method.

Example

The following example illustrates adding two PDF documents, an image, and a word document as attachments to a PDF document.

Document document = new Document();
document.Pages.Add(new Page(PageSize.Letter));

Label label = new Label("Embedded Files Example", 50, 20, 215, 0);
document.Pages[0].Elements.Add(label);
 
string fileOne = "DocumentA.pdf";
string fileTwo = "DocumentB.pdf";
string fileThree = "DPDFLogo.png";
string fileFour = "Doc1.docx";

EmbeddedFile embeddedFile1 = new EmbeddedFile(fileOne);
EmbeddedFile embeddedFile2 = new EmbeddedFile(fileTwo);
EmbeddedFile embeddedFile3 = new EmbeddedFile(fileThree);
EmbeddedFile embeddedFile4 = new EmbeddedFile(fileFour);

document.EmbeddedFiles.Add(embeddedFile1);
document.EmbeddedFiles.Add(embeddedFile2);
document.EmbeddedFiles.Add(embeddedFile3);
document.EmbeddedFiles.Add(embeddedFile4);

document.InitialPageMode = PageMode.ShowAttachments;

document.Draw(outputPath);

Dim document As New Document()
document.Pages.Add(New Page(PageSize.Letter))
Dim label As New Label("Embedded Files Example", 50, 20, 215, 0)
document.Pages(0).Elements.Add(label)

Dim fileOne As String = "DocumentA.pdf"
Dim fileTwo As String = "DocumentB.pdf"
Dim fileThree As String = "DPDFLogo.png"
Dim fileFour As String = "Doc1.docx"

Dim embeddedFile1 As New EmbeddedFile(fileOne)
Dim embeddedFile2 As New EmbeddedFile(fileTwo)
Dim embeddedFile3 As New EmbeddedFile(fileThree)
Dim embeddedFile4 As New EmbeddedFile(fileFour)

document.EmbeddedFiles.Add(embeddedFile1)
document.EmbeddedFiles.Add(embeddedFile2)
document.EmbeddedFiles.Add(embeddedFile3)
document.EmbeddedFiles.Add(embeddedFile4)

document.Draw(outputPath)
