示例源码

//Document:（文档）生成pdf必备的一个对象,生成一个Document示例

Document document = new Document(PageSize.A4, 30, 30, 5, 5);

//为该Document创建一个Writer实例：

PdfWriter.GetInstance(document, new FileStream(Server.MapPath("/upload/"+"Chap0101.pdf"), FileMode.Create));

//打开当前Document

document.Open();

//为当前Document添加内容：

document.Add(new Paragraph("Hello World"));

//另起一行。有几种办法建立一个段落，如：

Paragraph p1 = new Paragraph(new Chunk("This is my first paragraph.\n", FontFactory.GetFont(FontFactory.HELVETICA, 12)));

Paragraph p2 = new Paragraph(new Phrase("This is my second paragraph.", FontFactory.GetFont(FontFactory.HELVETICA, 12)));

Paragraph p3 = new Paragraph("This is my third paragraph.", FontFactory.GetFont(FontFactory.HELVETICA, 12));

//所有有些对象将被添加到段落中：

p1.Add("you can add string here\n\t");

p1.Add(new Chunk("you can add chunks \n")); p1.Add(new Phrase("or you can add phrases.\n"));

document.Add(p1); document.Add(p2); document.Add(p3);

//创建了一个内容为“hello World”、红色、斜体、COURIER字体、尺寸20的一个块：

Chunk chunk = new Chunk("Hello world", FontFactory.GetFont(FontFactory.COURIER, 20, iTextSharp.text.Font.COURIER, new iTextSharp.text.Color(255, 0, 0)));

document.Add(chunk);

//如果你希望一些块有下划线或删除线，你可以通过改变字体风格简单做到：

Chunk chunk1 = new Chunk("This text is underlined", FontFactory.GetFont(FontFactory.HELVETICA, 12, iTextSharp.text.Font.UNDEFINED));

Chunk chunk2 = new Chunk("This font is of type ITALIC | STRIKETHRU", FontFactory.GetFont(FontFactory.HELVETICA, 12, iTextSharp.text.Font.ITALIC | iTextSharp.text.Font.STRIKETHRU));

//改变块的背景

chunk2.SetBackground(new iTextSharp.text.Color(0xFF, 0xFF, 0x00));

//上标/下标

chunk1.SetTextRise(5);

document.Add(chunk1);

document.Add(chunk2);

//外部链接示例：

Anchor anchor = new Anchor("website", FontFactory.GetFont(FontFactory.HELVETICA, 12, iTextSharp.text.Font.UNDEFINED, new iTextSharp.text.Color(0, 0, 255)));

anchor.Reference = "http://itextsharp.sourceforge.net/";

anchor.Name = "website";

//内部链接示例：

Anchor anchor1 = new Anchor("This is an internal link\n\n");

anchor1.Name = "link1";

Anchor anchor2 = new Anchor("Click here to jump to the internal link\n\f");

anchor2.Reference = "#link1";

document.Add(anchor); document.Add(anchor1); document.Add(anchor2);

//排序列表示例：

List list = new List(true, 20);

list.Add(new iTextSharp.text.ListItem("First line"));

list.Add(new iTextSharp.text.ListItem("The second line is longer to see what happens once the end of the line is reached. Will it start on a new line?"));

list.Add(new iTextSharp.text.ListItem("Third line"));

document.Add(list);

//文本注释：

Annotation a = new Annotation("authors", "Maybe its because I wanted to be an author myself that I wrote iText.");

document.Add(a);

//包含页码没有任何边框的页脚。

HeaderFooter footer = new HeaderFooter(new Phrase("This is page: "), true);

footer.Border = iTextSharp.text.Rectangle.NO_BORDER;

document.Footer = footer;

//Chapter对象和Section对象自动构建一个树：

iTextSharp.text.Font f1 = new iTextSharp.text.Font();

f1.SetStyle(iTextSharp.text.Font.BOLD);

Paragraph cTitle = new Paragraph("This is chapter 1", f1);

Chapter chapter = new Chapter(cTitle, 1);

Paragraph sTitle = new Paragraph("This is section 1 in chapter 1", f1);

Section section = chapter.AddSection(sTitle, 1);

document.Add(chapter);

//构建了一个简单的表：

iTextSharp.text.Table aTable = new iTextSharp.text.Table(4, 4);

aTable.AutoFillEmptyCells = true;

aTable.AddCell("2.2", new Point(2, 2));

aTable.AddCell("3.3", new Point(3, 3));

aTable.AddCell("2.1", new Point(2, 1));

aTable.AddCell("1.3", new Point(1, 3));

document.Add(aTable);

//构建了一个不简单的表：

iTextSharp.text.Table table = new iTextSharp.text.Table(3);

table.BorderWidth = 1;

table.BorderColor = new iTextSharp.text.Color(0, 0, 255);

table.Cellpadding = 5;

table.Cellspacing = 5;

Cell cell = new Cell("header");

cell.Header = true;

cell.Colspan = 3;

table.AddCell(cell);

cell = new Cell("example cell with colspan 1 and rowspan 2");

cell.Rowspan = 2;

cell.BorderColor = new iTextSharp.text.Color(255, 0, 0);

table.AddCell(cell);

table.AddCell("1.1");

table.AddCell("2.1");

table.AddCell("1.2");

table.AddCell("2.2");

table.AddCell("cell test1");

cell = new Cell("big cell");

cell.Rowspan = 2;

cell.Colspan = 2;

cell.BackgroundColor = new iTextSharp.text.Color(0xC0, 0xC0, 0xC0);

table.AddCell(cell);

table.AddCell("cell test2");

// 改变了单元格“big cell”的对齐方式：

cell.HorizontalAlignment = Element.ALIGN_CENTER;

cell.VerticalAlignment = Element.ALIGN_MIDDLE;

document.Add(table);

//关闭Document

document.Close();
