Question

I’m using iTextsharp library to create PDF files. I can declare for A4 Landscape paper like this:

 Dim pdfTable As New PdfPTable(9)
pdfTable.WidthPercentage = 100
Dim pdfDoc As New Document(PageSize.A4.Rotate())

I’m wondering how I can set Height of pdfTable or A4 Height manually. Because there’s a lot more margin left at the bottom, and I need to put some text at that margin. Right now, I put a line of text at the bottom, the line’s got pushed to the new page.

Q1: How can I override the height of A4 paper provied by iTextsharp?

Q2: How can I create a custom size paper, say Width = 29cm, Height = 22cm?

Thank you.

You can use a custom PdfpageEvent to add text or a table or whatever to the footer.

Here is some code that adds a 4 column table to the footer (sorry it’s in C#):

public override void OnEndPage(PdfWriter writer, iTextSharp.text.Document document)
{
    base.OnEndPage(writer, document);

    PdfContentByte cb = writer.DirectContent;

    var footerTable = new PdfPTable(4);

    var columnWidth = (document.Right - document.LeftMargin) / 4;

    footerTable.SetTotalWidth(new float[] { columnWidth, columnWidth, columnWidth, columnWidth });

    var cell1 = new PdfPCell();
    cell1.AddElement(new Paragraph("Date:"));
    cell1.AddElement(new Paragraph(DateTime.Now.ToShortDateString()));
    footerTable.AddCell(cell1);

    var cell2 = new PdfPCell();
    cell2.AddElement(new Paragraph("Data:"));
    cell2.AddElement(new Paragraph("123456789"));
    footerTable.AddCell(cell2);

    var cell3 = new PdfPCell();
    cell3.AddElement(new Paragraph("Date:"));
    cell3.AddElement(new Paragraph(DateTime.Now.ToShortDateString()));
    footerTable.AddCell(cell3);

    var cell4 = new PdfPCell();
    cell4.AddElement(new Paragraph("Page:"));
    cell4.AddElement(new Paragraph(document.PageNumber.ToString()));
    footerTable.AddCell(cell4);

    footerTable.WriteSelectedRows(0, -1, document.LeftMargin, cell4.Height + 50, cb);
}

and this is the code that would call the above code:

var pdfWriter = PdfWriter.GetInstance(pdf, new FileStream(fileName, FileMode.Create));
pdfWriter.PageEvent = new CustomPdfPageEvent();
