我们正在使用iTextSharp5.5.5创建pdf，当将文本定位到页面底部时遇到了问题。我试图像图像一样设置绝对位置，但这不起作用。如何在页面底部显示段落（下面代码中的段落版权）？
var document = new Document(PageSize.A4.Rotate(), 10, 10, 10, 10);
PdfWriter pdfWriter = PdfWriter.GetInstance(document, new FileStream("Sample.pdf", FileMode.Create));
document.Open();
var paragraphCopyright = new Paragraph("This text should be at the very bottom of the page", new Font(Font.FontFamily.HELVETICA, 20f, Font.BOLD)); // this text should be at the bottom
paragraphCopyright.Alignment = 1;
document.Add(paragraphCopyright);
var imgLogo = iTextSharp.text.Image.GetInstance(@"logo.PNG");
imgLogo.ScaleAbsolute(120, 80);
imgLogo.SetAbsolutePosition(PageSize.A4.Rotate().Width - 140, 20);
document.Add(imgLogo);
document.Close();
您可以创建页脚类并使用它。
创建一个由PdfPageEventHelper继承的类。
在此类中创建表并编写页脚内容。
public partial class Footer : PdfPageEventHelper
{
public override void OnEndPage(PdfWriter writer, Document doc)
{
Paragraph footer = new Paragraph("THANK YOU", FontFactory.GetFont(FontFactory.TIMES, 10, iTextSharp.text.Font.NORMAL));
footer.Alignment = Element.ALIGN_RIGHT;
PdfPTable footerTbl = new PdfPTable(1);
footerTbl.TotalWidth = 300;
footerTbl.HorizontalAlignment = Element.ALIGN_CENTER;
PdfPCell cell = new PdfPCell(footer);
cell.Border = 0;
cell.PaddingLeft = 10;
footerTbl.AddCell(cell);
footerTbl.WriteSelectedRows(0, -1, 415, 30, writer.DirectContent);
}
}
在这之后
Document document = new Document(PageSize.A4, 50, 50, 25, 25);
var output = new FileStream(Server.MapPath("Demo.pdf"), FileMode.Create);
PdfWriter writer = PdfWriter.GetInstance(document, output);
// Open the Document for writing
document.Open();
//using footer class
writer.PageEvent = new Footer();.
Paragraph welcomeParagraph = new Paragraph("Hello, World!");
document.Add(welcomeParagraph);
document.Close();

另一种方式-您可以简单地在下面添加代码
Paragraph copyright = new Paragraph("© 2020 AO XXX. All rights reserved.", calibri8Black);
PdfPTable footerTbl = new PdfPTable(1);
footerTbl.TotalWidth = 300;
PdfPCell cell = new PdfPCell(copyright);
cell.Border = 0;
footerTbl.AddCell(cell);
footerTbl.WriteSelectedRows(0, -1, 30, 30, writer.DirectContent);
