Its very important in real time to convert the records or any statements into PDF,EXCEL,Word,TXT and some other formats too 🙂 now i will tell you how to generate PDF using iTextPdf API (simple API to generate PDFs in java), am going to cover…

• Inserting Image in PDF
• Inserting Table in PDF
• Inserting List in PDF
• Text formatting in PDF
• Adding new Pages in PDF
• Little Chunk

But before you start this application you must download iTextpdf related jar(s).

PdfGen.java

package pdf;

import java.io.File;
import java.io.FileOutputStream;
import java.io.OutputStream;
import java.util.Date;

import com.itextpdf.text.BaseColor;
import com.itextpdf.text.Chunk;
import com.itextpdf.text.Document;
import com.itextpdf.text.Element;
import com.itextpdf.text.Image;
import com.itextpdf.text.List;
import com.itextpdf.text.ListItem;
import com.itextpdf.text.Paragraph;
import com.itextpdf.text.pdf.PdfPCell;
import com.itextpdf.text.pdf.PdfPTable;
import com.itextpdf.text.pdf.PdfWriter;

public class PdfGen {

    public static void main(String[] args) {

        try {

              OutputStream file = new FileOutputStream(new File("C:\\PDF_Java4s.pdf"));
	          Document document = new Document();
	          PdfWriter.getInstance(document, file);

			//Inserting Image in PDF
			     Image image = Image.getInstance ("src/pdf/java4s.png");
			     image.scaleAbsolute(120f, 60f);//image width,height	

			//Inserting Table in PDF
			     PdfPTable table=new PdfPTable(3);

	                     PdfPCell cell = new PdfPCell (new Paragraph ("Java4s.com"));

				      cell.setColspan (3);
				      cell.setHorizontalAlignment (Element.ALIGN_CENTER);
				      cell.setPadding (10.0f);
				      cell.setBackgroundColor (new BaseColor (140, 221, 8));					               

				      table.addCell(cell);						               

				      table.addCell("Name");
				      table.addCell("Address");
				      table.addCell("Country");
                      table.addCell("Java4s");
				      table.addCell("NC");
				      table.addCell("United States");
				      table.setSpacingBefore(30.0f);       // Space Before table starts, like margin-top in CSS
				      table.setSpacingAfter(30.0f);        // Space After table starts, like margin-Bottom in CSS								          

			 //Inserting List in PDF
				      List list=new List(true,30);
			          list.add(new ListItem("Java4s"));
				      list.add(new ListItem("Php4s"));
				      list.add(new ListItem("Some Thing..."));		

			 //Text formating in PDF
	                Chunk chunk=new Chunk("Welecome To Java4s Programming Blog...");
					chunk.setUnderline(+1f,-2f);//1st co-ordinate is for line width,2nd is space between
					Chunk chunk1=new Chunk("Php4s.com");
					chunk1.setUnderline(+4f,-8f);
					chunk1.setBackground(new BaseColor (17, 46, 193));      

			 //Now Insert Every Thing Into PDF Document
		         document.open();//PDF document opened........			       

					document.add(image);

					document.add(Chunk.NEWLINE);   //Something like in HTML :-)

                    document.add(new Paragraph("Dear Java4s.com"));
	                document.add(new Paragraph("Document Generated On - "+new Date().toString()));	

					document.add(table);

					document.add(chunk);
					document.add(chunk1);

					document.add(Chunk.NEWLINE);   //Something like in HTML :-)							    

       				document.newPage();            //Opened new page
					document.add(list);            //In the new page we are going to add list

		         document.close();

			             file.close();

            System.out.println("Pdf created successfully..");

        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

Explanation

• Point number 1, just forget every thing 🙂 its very simple program, i will show you the road map
• First open OutputStream and give our output PDF file name [ line number 26 ]
• Create Document class object [ line number 27 ]
• Call getInstance() static method from PdfWriter class
• In getInstance() we have 2 parameters, 1 is document object and 2nd one is our OutputStream object
• Now jump to line number 70, we are calling open() method from Document object, means think PDF is opened now
• Come to line number 30, here am going to write some code to insert an image into the PDF document
• Create Image class object and loaded the image and adjusted the dimensions
• Come to line number 72, add your image object here 🙂
• line number 85 we have created new PDF page
• Similarly allllllllllllllll
