Hi,
Using the last iTextSharp library (5.0.2), I have an issue and didn’t find
on the web how to manage with this.
What I want to do :
- Create a pdf based on HTML
- Sign the pdf
The objective would be to create the whole .pdf before having to write it on
the hard disk.
When I’m trying to use my “Stream” to create a new PdfReader, I get the
following error :
An unhandled exception of type
'iTextSharp.text.exceptions.InvalidPdfException' occurred in itextsharp.dll
Additional information: PDF header signature not found.
My code :
------------------------------------------
Document doc = new Document(PageSize.A4);
PdfWriter writer = PdfWriter.GetInstance(doc, new FileStream(
Environment.CurrentDirectory + "\\testPdfCreation.pdf", FileMode.Create));
doc.Open();
string strURL = Environment.CurrentDirectory + "\\test.html";
Uri uri = new Uri(strURL);
FileWebRequest req = (FileWebRequest)WebRequest.Create(uri);
WebResponse resp = req.GetResponse();
Stream stream = resp.GetResponseStream();
StreamReader sr = new StreamReader(stream);
string html = sr.ReadToEnd();
List<iTextSharp.text.IElement> lt =
iTextSharp.text.html.simpleparser.HTMLWorker.ParseToList(new
StringReader(html),
null);
ColumnText ct = new ColumnText(writer.DirectContent);
ct.SetSimpleColumn(50, 50, PageSize.A4.Width - 50,
PageSize.A4.Height
- 50);
for (int k = 0; k < lt.Count; ++k)
ct.AddElement((IElement)lt[k]);
ct.Go();
doc.Close();
//--------------------
//!\ ERROR
PdfReader reader = new PdfReader(stream); //Same error:
PdfReader reader = new PdfReader(sr.BaseStream)
//--------------------
(…)
------------------------------------------
I tried many things but no evolution… I read on the net that we have to
close the document before being able to create a Pdfreader, but nothing
works for the moment.
Thanks in advance if you could help me.
Best regards, leparachute.
