Subject: [iText-questions] File does not start with %PDF- ( after using 
pdfstamper )

I have a situation where the user uploads a pdf file (template) and it is
stored in the SQL Server Table in a field which has an image datatype.
Everything worked well so far. Now the user wants some data written onto the
pdf dynamically over the template. I used pdfstamper to write the text over
the data retrieved from the table.

Steps Taken:

1) Saved the file to the local harddrive and i was able to bring the pdf up
without any issues.
2) Saved it back to the table and while retrieving the pdf via the web app.
I get the error message "File does not start with %PDF-"
3) I opened the file via notepad. Before overwriting with data and the file
starts with "%PDF-1.4
%âãÏÓ
1 0 obj<</Subtype...."
4) File after overwriting with data : the file looks like this "1 0
obj<</Subtype/Type1/" and it's clearly missing the PDF related information.

Is there any properties i could use to set the PDF information?

Has anyone encountered a similar situation? Please help!!

Thanks in advance,
-Matt

Below is the sample code snippet:

PdfReader pdfReader = new PdfReader(d.DisclosurePdf);
//PdfReader pdfReader = new PdfReader(@"d:\test\xyz.pdf");
PdfStamper ps = new PdfStamper(pdfReader, mStream,'\0');
PdfContentByte under = ps.GetUnderContent(1);
PdfContentByte over = ps.GetOverContent(1);
BaseFont bf = BaseFont.CreateFont(BaseFont.HELVETICA, BaseFont.WINANSI,
BaseFont.EMBEDDED);
// text over the existing page
over.BeginText();
over.SetFontAndSize(bf, 10);
over.SetTextMatrix(95, 650);
over.ShowText(DateTime.Now.ToShortDateString());
over.EndText();
over.BeginText();
over.SetFontAndSize(bf, 10);
over.SetTextMatrix(250, 650);
over.ShowText("5000.00");
over.EndText();
mStream.Seek(0, SeekOrigin.Begin);
ps.Close();
result = mStream.ToArray();
