Post subject:  Error try to read PDF with nested image
Hi,

we are using PdfSharp from sharpPDF-SL v2.0.50727 for reading pdf-files (It's a silverlight project).
But we have a problem when trying read a pdf wcich consists solely of an nested image (e.g. scanned image or fax).
The following call produces an error:

Code:
foreach (FileInfo loFileInfo in FileDialog.Files)
                {
                    lobmpimage = new BitmapImage();

                    loImageList = new ImageList();
                    loImageList.FileName = loFileInfo.Name;
                    .
                    .
                    .
                    else if (loFileInfo.Extension.ToUpper() == ".PDF")
                    {
                        loImageList.PdfFile = XPdfForm.FromStream(loFileInfo.OpenRead()); //that's where the error occures


The follwing error message is shown:

at Parser.ReadXRefTableAndTrailer(PdfReferenceTable xrefTable)
at Parser.ReadTrailer()
at PdfReader.Open(Stream stream, String password, PdfDocumentOpenMode openmode, PdfPasswordProvider passwordProvider)
at PdfReader.Open(Stream stream, String password, PdfDocumentOpenMode openmode)
at PdfReader.Open(Stream stream, PdfDocumentOpenMode openmode)
at PdfReader.Open(Stream stream)
at XPdfForm..ctor(Stream stream)
at XPdfForm.FromStream(Stream stream)
at SelectedFileConverter.btn_LoadFiles_Click(Object sender, RoutedEventArgs e)

at Control.OnMouseLeftButtonUp(Control ctrl, EventArgs e)
at JoltHelper.FireEvent(IntPtr unmanagedObj, IntPtr unmanagedObjArgs, Int32 argsTypeIndex, Int32 actualArgsTypeIndex, String eventName, UInt32 flags)

Thanks for any help in advance.

Greetings
Jans

So you are not using PDFsharp.

If the error also occurs with PDFsharp and if you provide us with that PDF file, we can take a look at the problem.
