Hello everybody, I am using iTextSharp to create my PDF document on the fly. Everything works fine, and i get no errors in the code; however, when i open created PDF it gives me error saying that document will be not displayed properly because it contain errors. Here is the code bellow that gives me a problem: public class pdfevents : PdfPageEventHelper { public override void OnEndPage(PdfWriter writer, Document document) { base.OnEndPage(writer, document); PdfContentByte cb = writer.DirectContent; cb.BeginText(); cb.SetTextMatrix(20, document.GetBottom(-30)); BaseFont bf = BaseFont.CreateFont(BaseFont.TIMES_ROMAN, BaseFont.CP1252, BaseFont.NOT_EMBEDDED); cb.SetFontAndSize(bf, 10); //thats is the piece of code that makes problems //if i remove it then document displays without error cb.MoveTo(15F, document.GetBottom(-15)); cb.SetLineWidth(0.5F); cb.LineTo(document.GetRight(0), document.GetBottom(-15)); cb.Stroke(); cb.ShowText(DateTime.Now.ToLongDateString()); int n = writer.PageNumber; cb.SetTextMatrix(document.GetRight(20), document.GetBottom(-30)); cb.ShowText(" - " + n + " - "); cb.EndText(); } } If i remove following lines : //thats is the piece of code that makes problems //if i remove it then document displays without error cb.MoveTo(15F, document.GetBottom(-15)); cb.SetLineWidth(0.5F); cb.LineTo(document.GetRight(0), document.GetBottom(-15)); Then i am getting no error opening generated PDF, otherwise i can open PDF and see the document and it's content including the line. However, then i get error that document been generated with error. Can somebody tell me what is wrong ? Thanks in advance. cb.Stroke();
