Java Programing laungage

In this example we are going to set background color of a PDF using java. In this example we are using setBackgroundColor(Color object) to set the background color.

There are basic five steps to create PDF:

We are creating and object of rectangle.This is basically for size of page.

Rectangle pageSize = new Rectangle(216, 720);

We are setting the background color of PDF

pageSize.setBackgroundColor(new java.awt.Color(0xFF, 0xFF, 0xDE));

Step1: Creation of a document-object

Document document = new Document();

Step2: Create a writer that listens to the document and directs a PDF-stream to a file.

PdfWriter.getInstance(document, new FileOutputStream("SetBackgroundcolr.pdf"));

Step3: Open the document

document.open();

Step4: Add a paragraph to the document, set size and create new page

document.add(new Paragraph(
"The backgroundcolor of the Rectangle used for this PageSize,
 is #FFFFDE."));
 document.add(new Paragraph(
"That's why the background of this document is yellowish..."));

Step5: Close the document

document.close();

Example:

package com.itext.pdf.example.r4r;
import java.io.FileOutputStream;
import java.io.IOException;
import com.lowagie.text.Document;
import com.lowagie.text.DocumentException;
import com.lowagie.text.Paragraph;
import com.lowagie.text.Rectangle;
import com.lowagie.text.pdf.PdfWriter;

/*** In this example we are going to set the background 
     color of a PDF file.
 * We are first creating a PDF file and then setting the color 
   by using setBackgroundColor(Color objectOfColor)
 */
public class SetBackgroundColorOfPDF {
/*** Creates a PDF document and set its background color.
 */
public static void main(String[] args) {
  System.out.println("Set backgroundcolor of PDF");
        
/Here we are creating and object of rectangle. 
This is basically for size of page.  

Rectangle pageSize = new Rectangle(236, 720);

/Here we are setting the background color of PDF 
        
pageSize.setBackgroundColor(new java.awt.Color(0xFF, 0xFF, 0xDE));
        
/ Step 1: Here we are creating an object of a document
  
Document document = new Document(pageSize);
  try {
            
/ Step2: Here we are creating a writer that listens to
      the document and directs a PDF-stream to a file
            
PdfWriter.getInstance(document, new FileOutputStream(
	"SetBackgroundcolr.pdf"));
            
/ Step 3:Here we are opening the document
 
document.open();
            
/ Step 4: Here we are adding some paragraphs to the document
            
document.add(new Paragraph(
"The backgroundcolor of the Rectangle used for this PageSize,
is #FFFFDE"));
document.add(new Paragraph(
"That's why the background of this document is yellowish..."));
            
 }
 catch(DocumentException de) {
    System.err.println(de.getMessage());
 }
 catch(IOException ioe) {
	System.err.println(ioe.getMessage());
 }
        
/ Step 5: Here we are closing  the document
 document.close();
    }
}
