1.创建简单的PDF文件

package console.pdf;

import java.io.FileNotFoundException;

import java.io.FileOutputStream;

import com.itextpdf.text.Document;

import com.itextpdf.text.DocumentException;

import com.itextpdf.text.PageSize;

import com.itextpdf.text.Paragraph;

import com.itextpdf.text.pdf.PdfWriter;

/**

* 使用iText生成PDF文件

*/

public class CreatePDF {

public static void main(String[] args) {

CreatePDF p001 = new CreatePDF();

String filename = "P001.pdf";

p001.createPDF(filename);

}

public void createPDF(String filename) {

// step 1

Document document = new Dhttp://ocument(PageSize.A4);

// step 2

try {

PdfWriter.getInstance(document, new FileOutputStream(filename));

document.addTitle("ID.NET");

document.addAuthor("dotuian");

document.addSubject("This is the subject of the PDF file.");

document.addKeywords("This is the keyword of the PDF file.");

// step 3

document.open();

// step 4

document.add(new Paragraph("Hello World!"));

} catch (FileNotFoundException e) {

e.printStackTrace();

} catch (DocumentException e) {

e.printStackTrace();

} finally {

// step 5

document.close();

}

}

}

2.在PDF文件中添加Table

package console.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.Phrase;

import com.itextpdf.text.Rectangle;

import com.itextpdf.text.pdf.PdfPCell;

import com.itextpdf.text.pdf.PdfPTable;

import com.itextpdf.text.pdf.PdfWriter;

/**

* 使用iText生成PDF文件

* 在PDF文件中创建表格

*/

public class TableOfPDF {

public static void main(String[] args) {

TableOfPDF p001 = new TableOfPDF();

String filename = "P002.pdf";

p001.createPDF(filename);

}

public void createPDF(String filename) {

// step 1

Document document = new Document(PageSize.A4);

// step 2

try {

PdfWriter.getInstance(document, new FileOutputStream(filename));

document.addTitle("ID.NET");

document.addAuthor("dotuian");

documARHeXcZtlment.addSubject("This is the subject of the PDF file.");

document.addKeywords("This is the keyword of the PDF file.");

// step 3

document.open();

// step 4

PdfPTable table = createTable1();

document.add(table);

table = createTable2();

table.setSpacingBefore(5);

table.setSpacingAfter(5);

document.add(table);

table = createTable3();

document.add(table);

table = createTable4();

table.setSpacingBefore(5);

table.setSpacingAfter(5);

document.add(table);

table = createTable5();

document.add(table);

table = createTable6();

document.add(table);

} catch (FileNotFoundException e) {

e.printStackTrace();

} catch (DocumentException e) {

e.printStackTrace();

} finally {

// step 5

document.close();

}

}

*/

3.在PDF文件中添加图片，并且指定文本位置

package console.pdf;

import com.itextpdf.text.pdf.PdfContentByte;

import com.itextpdf.text.pdf.PdfWriter;

/**

* 使用iText生成PDF文件

* 在PDF文件中添加背景图片，并指定文本在PDF文件中的位置

*/

public class BackgroundImageOfPDF {

public static void main(String[] args) {

BackgroundImageOfPDF p001 = new BackgroundImageOfPDF();

String filename = "P003.pdf";

p001.createPDF(filename);

}

public void createPDF(String filename) {

// step 1

Document document = new Document(PageSize.A4.rotate(),0,0,0,0);

// step 2

try {

PdfWriter pdfwriter = PdfWriter.getInstance(document, new FileOutputStream(filename));

document.addTitle("ID.NET");

document.addAuthor("dotuian");

document.addSubject("This is the subject of the PDF file.");

document.addKeywords("This is the keyword of the PDF file.");

// step 3

document.open();

// step 4

Image image = Image.getInstance("bg.jpg");

document.add(image);

PdfContentByte pdfContentByte = pdfwriter.getDirectContent();

pdfContentByte.beginText();

BaseFont bf = BaseFont.createFont(BaseFont.TIMES_ROMAN,BaseFont.WINANSI,BaseFont.EMBEDDED);

pdfContentByte.setFontAndSize(bf, 12);

for (int i = 0; i <= 842; i = i + 50) {

for (int j = 0; j <= 595; j = j + 20) {

pdfContentByte.setTextMatrix(i, j);

pdfContentByte.showText("(" + i + ":" + j + ")");

}

}

pdfContentByte.endText();

} catch (FileNotFoundException e) {

e.printStackTrace();

} catch (DocumentException e) {

e.printStackTrace();

} catch (Exception e) {

e.printStackTrace();

} finally {

// step 5

document.close();

}
