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,Keywordspublic void createCplPdf() throws FileNotFoundException, DocumentException {// 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, 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.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"));doc.close();}public static void main(String[] args) throws FileNotFoundException,DocumentException {PdfTest test = new PdfTest();// test.createPdf();test.createCplPdf();}}

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();
