测试类:

package com.lucene.test.pdf;

import java.io.FileNotFoundException;
import java.io.FileOutputStream;

import com.itextpdf.text.BaseColor;
import com.itextpdf.text.Document;
import com.itextpdf.text.DocumentException;
import com.itextpdf.text.PageSize;
import com.itextpdf.text.Paragraph;
import com.itextpdf.text.Rectangle;
import com.itextpdf.text.pdf.PdfWriter;

public class PdfTest {

	private static String FILE_DIR = "c:/temp/lucene/data/";

	// 创建pdf文件
	public void createPdf() throws FileNotFoundException, DocumentException {
		// Step 1—Create a Document.
		Document document = new Document();
		// Step 2—Get a PdfWriter instance.
		PdfWriter.getInstance(document, new FileOutputStream(FILE_DIR
				+ "createSamplePDF.pdf"));
		// Step 3—Open the Document.
		document.open();
		// Step 4—Add content.
		document.add(new Paragraph("Hello World,shit"));
		// Step 5—Close the Document.
		document.close();
	}

	// 2、页面大小,页面背景色,页边空白,Title,Author,Subject,Keywords
	public void createCplPdf() throws FileNotFoundException, DocumentException {

		// 页面背景色
		rect.setBackgroundColor(BaseColor.ORANGE);

		Document doc = new Document(rect);

		PdfWriter writer = PdfWriter.getInstance(doc, new FileOutputStream(
				FILE_DIR + "createSamplePDF.pdf"));

		// PDF版本(默认1.4)
		writer.setPdfVersion(PdfWriter.PDF_VERSION_1_2);

		// 文档属性
		doc.addTitle("Title@sample");

		doc.addSubject("Subject@iText sample");
		doc.addKeywords("Keywords@iText");
		doc.addCreator("Creator@iText");

		// 页边空白
		doc.setMargins(10, 20, 30, 40);

		doc.open();
		doc.add(new Paragraph("Hello World"));

		doc.close();

	}

生成一个PDF

//Step 1—Create a Document.
Document document = new Document();
//Step 2—Get a PdfWriter instance.
PdfWriter.getInstance(document, new FileOutputStream(FILE_DIR + "createSamplePDF.pdf"));
//Step 3—Open the Document.
document.open();
//Step 4—Add content.
document.add(new Paragraph("Hello World"));
//Step 5—Close the Document.
document.close();

2、页面大小,页面背景色,页边空白,Title,Author,Subject,Keywords

//页面大小
Rectangle rect = new Rectangle(PageSize.B5.rotate());
//页面背景色
rect.setBackgroundColor(BaseColor.ORANGE);

Document doc = new Document(rect);

PdfWriter writer = PdfWriter.getInstance(doc, out);

//PDF版本(默认1.4)
writer.setPdfVersion(PdfWriter.PDF_VERSION_1_2);

//文档属性
doc.addTitle("Title@sample");
doc.addAuthor("Author@rensanning");
doc.addSubject("Subject@iText sample");
doc.addKeywords("Keywords@iText");
doc.addCreator("Creator@iText");

//页边空白
doc.setMargins(10, 20, 30, 40);

doc.open();
doc.add(new Paragraph("Hello World"));

3、设置密码

PdfWriter writer = PdfWriter.getInstance(doc, out);

// 设置密码为："World"
writer.setEncryption("Hello".getBytes(), "World".getBytes(),
		PdfWriter.ALLOW_SCREENREADERS,
		PdfWriter.STANDARD_ENCRYPTION_128);

doc.open();
doc.add(new Paragraph("Hello World"));

4添加Page

document.open();
document.add(new Paragraph("First page"));
document.add(new Paragraph(Document.getVersion()));

document.newPage();
writer.setPageEmpty(false);

document.newPage();
document.add(new Paragraph("New page"));

5添加水印(背景图)

//图片水印
PdfReader reader = new PdfReader(FILE_DIR + "setWatermark.pdf");
PdfStamper stamp = new PdfStamper(reader, new FileOutputStream(FILE_DIR
		+ "setWatermark2.pdf"));

Image img = Image.getInstance("resource/watermark.jpg");
img.setAbsolutePosition(200, 400);
PdfContentByte under = stamp.getUnderContent(1);
under.addImage(img);

//文字水印
PdfContentByte over = stamp.getOverContent(2);
over.beginText();
BaseFont bf = BaseFont.createFont(BaseFont.HELVETICA, BaseFont.WINANSI,
		BaseFont.EMBEDDED);
over.setFontAndSize(bf, 18);
over.setTextMatrix(30, 30);
over.showTextAligned(Element.ALIGN_LEFT, "DUPLICATE", 230, 430, 45);
over.endText();

//背景图
Image img2 = Image.getInstance("resource/test.jpg");
img2.setAbsolutePosition(0, 0);
PdfContentByte under2 = stamp.getUnderContent(3);
under2.addImage(img2);

stamp.close();
reader.close();
