Question

What I need to do is;

1. Get a pdf from sharepoint
2. Get a single page, using PDFSharp
3. Return that to the view and display that page

What I have thus far is;

        context.Response.ClearHeaders();
        context.Response.ContentType = "application/pdf";            
        context.Response.AddHeader("content-disposition", "inline; filename=Something.pdf");

        // Get a fresh copy of the sample PDF file from Sharepoint later on
        string filename = @"book.pdf";

        // Open the file
        PdfDocument inputDocument = CompatiblePdfReader.Open(filename, PdfDocumentOpenMode.Import);

        PdfDocument outputDocument = new PdfDocument();
        outputDocument.Version = inputDocument.Version;
        outputDocument.Info.Title = "Pages 1 to 30";
        outputDocument.Info.Author = "Slappy";

        outputDocument.AddPage(inputDocument.Pages[1]);

        MemoryStream ms = new MemoryStream();
        outputDocument.Save(ms, false);

        ms.WriteTo(context.Response.OutputStream);

What I can’t figure out is how to then display that within the web page.

I have this;

<script src="../../Scripts/jquery-1.6.4.min.js" type="text/javascript"></script>
<script src="../../Scripts/jquery.media.js" type="text/javascript"></script>
<script src="../../Scripts/jquery.metadata.js" type="text/javascript"></script>

<script>
    $(function () {
        $.ajax({ url: '/GetBookPage.ashx',
            success: function (result) {
                $("a.media").attr('href', result);
                $('a.media').media({ width: 800, height: 600 });
            },
            async: false
        });
    });
</script>

<a class="media">PDF File</a>

The above works if I save the pdf to the filesystem and then point the href at that file.

Answer 1

With the following handler:

public class GetBookPage : IHttpHandler
    {

        public void ProcessRequest(HttpContext context)
        {
            string filePath = @"c:\somepath\test.pdf";
            context.Response.ContentType = "application/pdf";
            context.Response.AddHeader("content-disposition", "inline; filename=test.pdf");
            context.Response.WriteFile(filePath);
            context.Response.End(); 
        }

        public bool IsReusable
        {
            get
            {
                return false;
            }
        }
    }

I was able to get the PDF to display inline if you do the following:

<script type="text/javascript">
   $(function () {
        $('a.media').media({ width: 800, height: 600 });
    });
</script>

<a class="media" href="/GetBookPage.ashx?.pdf">PDF File</a>

The plugin is using the url (or more accurately the extension) to build the proper media container on the page. If you don’t have “.pdf” it won’t work as expected.
