Hey Guys,
I apologize that I did not fix my subject line in my last email. I realize
that it is probably pretty annoying.
Thanks, Brian

No problem. The "shortened for brevity" was just for the filler text anyway. I
am also including the code for the footer as well (just in case that makes any
difference). I appreciate the help!

It may be a rounding bug. Please post the complete code required to generate
the PDF ([Shortened for brevity] is not very useful and the devil is always
in the details).

Subject: [iText-questions] Small problem with PdfPCell spanning more thanone
page
Hey Guys,
I am using iTextSharp 4.1.6.0. I noticed that when a PdfPCell contains text
that forces it to span multiple pages, if the final line of text before the
page break falls in just the right place, that line will be repeated on the
next page (generic sample attached). I worked around it by adjusting the
top and bottom margin by a point or two.
The meat of the code I used to create the attachment is below. I am unsure
if the problem is with my code, iText, Reader, or some combination as I was
unable to find anything in the documentation or searches.
MemoryStream m = new MemoryStream();
Document objDocument = new Document(PageSize.LETTER, 20f, 20f,
35f, 33f);
Response.ContentType = "application/pdf";
PdfWriter objWriter = PdfWriter.GetInstance(objDocument, m);
objWriter.PageEvent = objMyEvent;
objDocument.Open();
PdfPTable objTable = new PdfPTable(1);
PdfPCell objCell = null;
objTable.SplitLate = false;
for (int i = 0; i < 4; i++)
{
objCell = new PdfPCell(new Phrase("Lorem ipsum dolor sit
amet [Shortened for brevity]", FontFactory.GetFont("Arial", 10f)));
objTable.AddCell(objCell);
}
objDocument.Add(objTable);
objDocument.Close();
Response.OutputStream.Write(m.GetBuffer(), 0,
m.GetBuffer().Length);
Response.OutputStream.Flush();
Response.OutputStream.Close();
Thanks,
Brian
