Extra space inserted on new pages when creating PDFs with iTextSharp

I'开发者_StackOverflow中文版m using iTextSharp 5.0.5 to create dynamic PDFs (asp.net c#), and I'm having problems with an extra space being inserted when creating a new page. The first page looks fine but on any additional pages the extra space appears at the top.

I've made a mini example that inserts a new page with a logo and a title for each article in a list. If I only insert the logo or only the title it works fine, but if I try to insert both there's an extra space coming from somewhere. Anyone got any ideas of what I'm doing wrong?

public static void CreatePDF(List<Item> Articles)
{
    Document document = new Document(PageSize.A4, 35, 35, 35, 35);
    MemoryStream memoryStream = new MemoryStream();
    PdfWriter writer = PdfWriter.GetInstance(document, memoryStream);

    document.Open();

    for (int i = 0; i < Articles.Count; i++)
    {
        if (i > 0)
        {
            document.NewPage();
        }

        Image logo = Image.GetInstance(@"C:\logo.gif");
        document.Add(logo);

        Paragraph title = new Paragraph("test title", new Font(Font.FontFamily.HELVETICA, 20, Font.NORMAL, CMYKColor.BLACK));
        document.Add(title);
    }

    document.Close();

    SendPDFResponse(memoryStream, "myfile.pdf");
}

Thanks,

Annelie

There's no extra space on the pages that follow page 1. The problem is that there's less space on page 1. No, this is not a joke. The problem is caused by the "leading" (that is: the space between two lines). The initial value for the leading is 0. When you add content to a document, this value changes to a value different from 0.

What is the leading you're using throughout the document? You should set this as the initial leading with the method setInitialLeading() in PdfWriter.

That sounds like a bug. I suspect some relatively new aspect of layout isn't being reset properly between pages.

Would you mind cross-posting this to the itext-questions mailing list?
