Buonasera,
ho fatto un pagina view che permette di mettere la firma tramite un canvas in un documento online.
il problema è che Itextsharp nel controller non becca l'immagine e mi ferma dando l'errore:
URI NON RICONOSCIUTO Il codice che utilizzo nel controller è:
[HttpPost]
[ValidateInput(false)]
public ActionResult Index(string TxtHtmlCode)
{
StringReader sr = new StringReader("<html>"+ TxtHtmlCode + "</html>");
Document pdfDoc = new Document(PageSize.A4, 10f, 10f, 10f, 0f);
// HTMLWorker htmlparser = new HTMLWorker(pdfDoc); --> questo me lo segnala come deprecato
HTMLWorker htmlparser = new HTMLWorker(pdfDoc);
using (MemoryStream memoryStream = new MemoryStream())
{
PdfWriter writer = PdfWriter.GetInstance(pdfDoc, memoryStream);
pdfDoc.Open();
htmlparser.Parse(sr);
pdfDoc.Close();
byte[] bytes = memoryStream.ToArray();
memoryStream.Close();
Response.Clear();
Response.ContentType = "application/pdf";
Response.AddHeader("Content-Disposition", "attachment; filename=Invoice.pdf");
Response.Buffer = true;
Response.Cache.SetCacheability(HttpCacheability.NoCache);
Response.BinaryWrite(bytes);
Response.End();
Response.Close();
}
return View();
}
la stringa che mando
"TxtHtmlCode" contiene il codice html di tutta la pagina compresa la firma che è di questo formato:

un altra cosa che mi manca è salvare il file direttamente in una cartella sul server che se non presente la crea.
Grazie mille e complimenti per la professionalita con cui gestite questa community
