changing Background Color

In this program, we are going to tell you how you can change background color of a pdf file. You can change the background color of any chunk with the help of setBackground(Color color).

In this example, we are creating a chunk then we use setBackground(Color color) to set the background color of that chunk. Here we pass the object of Color by using

new Color(0xFF, 0xFF, 0x00). We are passing three
    hexadecimal values into the Color constructor. Which is used to create the
    object of the Color.

Code Description:

setBackground(Color color):
If you want to change the background color then we use this method. This method is used to change the color of chunk of text into the chunk object. We use this for set the background color of any text.

setTextRise(float):
There are some methods that can be invoked on a Chunk. The method setTextRise(float f)is used to write the chunks in super or subscript.

The code of the program is given below:


import java.awt.Color;

import java.io.FileOutputStream;

import java.io.IOException;

import com.lowagie.text.Chunk;

import com.lowagie.text.Document;

import com.lowagie.text.DocumentException;

import com.lowagie.text.FontFactory;

import com.lowagie.text.Paragraph;

import com.lowagie.text.pdf.PdfWriter;

public class changeBackgroundColor {

 public static void main(String[] args)throws Exception {

    System.out.println("Background color");

           Document document = new Document();

    PdfWriter.getInstance(document,new FileOutputStream

("cahngeBackgroundColor.pdf"));

      document.open();

      Chunk chunk =new Chunk("RoseIndia.net"); 

      chunk.setBackground(new Color(0xFF, 0xFF, 0x00));

      Paragraph paragraph = new Paragraph("The following chunk is ");

      paragraph.add(chunk);

      document.add(paragraph);

      Chunk chunk2,chunk3;

      chunk2 = new Chunk("RoseIndia.net");

      chunk2.setBackground(new Color(0xb0, 0xb0, 0xb0));

      document.add(chunk2);

      chunk3 = new Chunk("RoseIndia.net");

      chunk3.setTextRise(8);

      chunk3.setBackground(new Color(0xFF, 0xDE, 0xAD));

                        document.add(chunk3);      

                  document.add(paragraph);

            document.close();

  }

}
