In this section, you will learn how to make a program by which you can define the strokeWidth and strokeColor. You can learn also to change the outline of the text. You can define the width and the color of the strokes used to draw the character. iText api provides a method setTextRenderMode(int mode, float strokeWidth, Color strokeColor).

Code Description:

In this example, we are using setTextRenderMode(int mode,float strokeWidth,Color strokeColor) method for define the strokeWidth, stokeColor and the mode. We are giving more details about this method following:
 

setTextRenderMode(int mode,float strokeWidth,Color strokeColor):
With the setTextRenderMode(int mode,float strokeWidth,Color strokeColor) we can change the outline of the text.We are passing here three parameters. First is  int  mode it can  be one of the following values:

  1. PdfContentByte.TEXT_RENDER_MODE_FILL: The mode is used for  glyphs fontcolor, the strokeWidth and strokeColor don't play a role here.
  2. PdfContentByte.TEXT_RENDER_MODE_STROKE: We will only see the outline of the glyphs, with the given strokeWidth and strokeColor.
  3. PdfContentByte.TEXT_RENDER_MODE_FILL_STROKE: The glyphs will be filled with the font color and will have an outline with the given strokeWidth and strokeColor.
  4. PdfContentByte.TEXT_RENDER_MODE_INVISIBLE: The glyphs will be invisible.

The second  strokeWidth and the thread one is stroke Color to set the width of and color of the text.

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.Phrase;
import com.lowagie.text.pdf.PdfContentByte;
import com.lowagie.text.pdf.PdfWriter;
public class exampleOfEndOfLine {
  public static void main(String[] args)throws Exception {
    System.out.println("Example of End of Line");
    Document document = new Document();
    PdfWriter.getInstance(document,
new FileOutputStream("EndOfLinepdf.pdf"));
                   document.open();
      Chunk chunk = new Chunk("Rose India 
.Net-->Rose India .Net ");
      for (int i = 0; i < 5; i++) {
        chunk.setTextRenderMode(PdfContentByte
.TEXT_RENDER_MODE_STROKE, 0.5f,
 new Color(i * 35, i * 30, i * 35));
        document.add(chunk);
      }
      document.newPage();
      Phrase p = new Phrase(16f);
      for (int i = 0; i < 5; i++) {
        chunk = new Chunk("Rose India .Net-->Rose
 India .Net ");
        chunk.setTextRenderMode(PdfContentByte.TEXT_RENDER_MODE_STROKE, 0.5f,
 new Color(i * 35, i * 30, i * 35));
        p.add(chunk);
      }
      document.add(p);
      document.close();
  }
} 

The output of the program is given below:
