1.
using iTextSharp.text;
using iTextSharp.text.pdf;
2.设置页面大小
iTextSharp.text.Rectangle pageSize = new iTextSharp.text.Rectangle(610f, 760f);
设置背景颜色
pageSize.BackgroundColor = new BaseColor(100,100,100);
3.创建文档：
Document document = new Document(pageSize);
对于一些常用尺寸比如：A4、A5A6可以使用PageSize类，如果是横向页面可以调用它的Rotate方法。eg:
PageSize.A4.Rotate().
设置margion:
Document doc = new Document(PageSize.A4.Rotate(), 5f, 5f, 5f, 5f);
4.创建writer
PdfWriter pw = PdfWriter.GetInstance(doc, new FileStream(@"...my.pdf",FileMode.OpenOrCreate,FileAccess.ReadWrite));
5.设置相关信息：
BaseFont baseFT = BaseFont.CreateFont(@"c:windowsfontsSIMHEI.TTF", BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED);
iTextSharp.text.Font font = new iTextSharp.text.Font(baseFT); //写入一个段落, Paragraph
#region 设置PDF的头信息，一些属性设置，在Document.Open 之前完成
doc.AddAuthor("尚层装饰");
doc.AddCreationDate();
doc.AddCreator("AddCreator");
doc.AddSubject("AddSubject");
doc.AddTitle("title");
doc.AddKeywords("111");
//自定义头
doc.AddHeader("Expires", "0");
#endregion
doc.Open();
doc.NewPage();
6.插入文字：
Paragraph ph = new Paragraph("PPPPpppzzzzpppPPPP" + "", font);
ph.Alignment = iTextSharp.text.Rectangle.ALIGN_CENTER;
doc.Add(ph);
7.插入图片
iTextSharp.text.Image image =
iTextSharp.text.Image.GetInstance(@"...20140527030942838.png");
image.Alignment = iTextSharp.text.Image.MIDDLE_ALIGN;
//image.SetAbsolutePosition(0f, 40f);
image.ScaleToFit(610f, 760f);
doc.Add(image);
8.插入表格：
iTextSharp.text.pdf.PdfPTable table = new iTextSharp.text.pdf.PdfPTable(2); // 表格有 2 列
iTextSharp.text.pdf.PdfPCell cell = new iTextSharp.text.pdf.PdfPCell(); // 创建单元格
cell.AddElement(new Phrase("sfdsdf"));
cell.Colspan = 2;
table.AddCell(cell);
//cell.HorizontalAlignment=1; // 在单元格中添加数据
table.SetWidths(new int[]{200, 100});
table.AddCell("1"); // 将单元格加入到表格中
table.AddCell("2"); // 将单元格加入到表格中
table.AddCell("1"); // 将单元格加入到表格中
table.AddCell("2"); // 将单元格加入到表格中
table.AddCell("1"); // 将单元格加入到表格中
table.AddCell("2"); // 将单元格加入到表格中
table.HorizontalAlignment = 1;
doc.Add(table);
doc.Close();
