Hello, 
I am trying to use the export image example to export images from a pdf.
The pdf was created with pdfsharp, basically it contains only jpeg images created with this code:
Code:
PdfPage page = document.AddPage();
page.Size = PageSize.A4;
XGraphics gfx = XGraphics.FromPdfPage(page);
using (XImage image = XImage.FromFile(imageFile))
{
   gfx.DrawImage(image, 0, 0, page.Width, page.Height);
   }
When I run the code sample I get an exception in this method:
Code:
static void ExportImage(PdfDictionary image, ref int count)
        {
            string filter = image.Elements.GetName("/Filter");
            switch (filter)
            {
                case "/DCTDecode":
                    ExportJpegImage(image, ref count);
                    break;
                /*case "/FlateDecode":
                    ExportAsPngImage(image, ref count);
                    break;*/
            }
        }
when it tries to read the filter it says object is not a string.
Any advice? 
Thank you
