Aspose.Pdf可以为PDF文件添加各种形式的注释，包括将swf文件作为注释添加进PDF文件中，这一操作可以通过简单的代码片段实现。

下面是代码示例：

**C\#**

>     //Open the PDF document
>     Document doc = new Document("d:/pdftest/input.pdf");
>     // get reference of the page to which you need to add the annotation
>     Page page = doc.Pages[1];
>     // create ScreenAnnotation object with .swf multimedia file as an argument
>     ScreenAnnotation annotation = 
>        new ScreenAnnotation(page, new Aspose.Pdf.Rectangle(0, 400, 600, 700),
>        @"E:\First_Application_with_Aspose.Pdf_for_.NET.swf");
>     // add the annotation to annotations collection of page
>     page.Annotations.Add(annotation);
>     // save the update PDF document with annotation
>     doc.Save("d:/pdftest/Pdf_Filesample_with_SWF.pdf");

**VB.NET**

>     'Open the PDF document
>     Dim doc As Document = New Document("d:/pdftest/input.pdf")
>     ' get reference of the page to which you need to add the annotation
>     Dim page As Page = doc.Pages(1)
>     ' create ScreenAnnotation object with .swf multimedia file as an argument
>     Dim annotation As ScreenAnnotation = 
>         New ScreenAnnotation(page, New Aspose.Pdf.Rectangle(0, 400, 600, 700), 
>        "E:\First_Application_with_Aspose.Pdf_for_.NET.swf")
>     ' add the annotation to annotations collection of page
>     page.Annotations.Add(annotation)
>     ' save the update PDF document with annotation
>     doc.Save("d:/pdftest/Pdf_Filesample_with_SWF.pdf")
