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、A5\A6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:\windows\fonts\SIMHEI.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();

iTextSharp.text.Rectangle pageSize = new iTextSharp.text.Rectangle(610f, 360f);

Document doc = new Document(pageSize, 0f, 0f, 0f, 0f);

//设置边界

MemoryStream Memory = new MemoryStream();

try

BaseFont baseFT = BaseFont.CreateFont(@"c:\windows\fonts\SIMHEI.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.AddCreator("" + model.FirstOrDefault().SliCreateTime + "");

doc.AddSubject("");

//自定义头

#endregion

iTextSharp.text.Image image =

image.Alignment = iTextSharp.text.Image.MIDDLE_ALIGN;

// image.SetAbsolutePosition(0f, 40f);

image.ScaleToFit(610f, 360f);

doc.Add(image);
