Rendering Example

In this section, you will learn how to make a program by which you can make a render page. iText api provides a method setTextRenderMode(int mode,float strokeWidth,Color strokeColor).We can gives various color and int mode.

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,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:

PdfContentByte.TEXT_RENDER_MODE_FILL:The mode is used for glyphs fontcolor, the strokeWidth and strokeColor don't play a role here.

PdfContentByte.TEXT_RENDER_MODE_STROKE: We will only see the outline of the glyphs, with the given strokeWidth and strokeColor.

PdfContentByte.TEXT_RENDER_MODE_FILL_STROKE: The glyphs will be filled with the fontcolor and will have an outline with the given strokeWidth and strokeColor.

PdfContentByte.TEXT_RENDER_MODE_INVISIBLE: The glyphs will be invisible.

The second one is stroke Color to set the color of the text.

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:

PdfContentByte.TEXT_RENDER_MODE_FILL:The mode is used for glyphs fontcolor, the strokeWidth and strokeColor don't play a role here.

PdfContentByte.TEXT_RENDER_MODE_STROKE: We will only see the outline of the glyphs, with the given strokeWidth and strokeColor.

PdfContentByte.TEXT_RENDER_MODE_FILL_STROKE: The glyphs will be filled with the fontcolor and will have an outline with the given strokeWidth and strokeColor.

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.Paragraph;

import com.lowagie.text.pdf.PdfContentByte;

import com.lowagie.text.pdf.PdfWriter;

public class exampleOFRendering 

          {

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

              {

    System.out.println("Example of Rendering");    

    Document document = new Document();

    PdfWriter.getInstance(document,

new FileOutputStream("Rendering.pdf"));

      document.open();

      Paragraph p = new Paragraph("Rose Text Rendering:");

      document.add(p);

      Chunk chunk = new Chunk("Rendering Test");

      chunk.setTextRenderMode(PdfContentByte.

TEXT_RENDER_MODE_FILL, 100f, new Color(0xc0, 0x00, 0x0f));

      document.add(chunk);

      document.add(Chunk.NEWLINE);

      chunk.setTextRenderMode(PdfContentByte.

TEXT_RENDER_MODE_FILL_STROKE, 0.3f, new Color(0xFc, 0x00, 0x00));

      document.add(chunk);

      document.add(Chunk.NEWLINE);

      chunk.setTextRenderMode(PdfContentByte.

TEXT_RENDER_MODE_INVISIBLE, 100f, new Color(0x0c, 0xF0, 0x00));

      document.add(chunk);

      document.add(Chunk.NEWLINE);

      chunk.setTextRenderMode(PdfContentByte.

TEXT_RENDER_MODE_FILL_STROKE, 0.3f, new Color(0x0c, 0x00, 0xF0));

      document.add(chunk);

      document.add(Chunk.NEWLINE);

      Chunk bold = new Chunk("This looks like STROKE for Bold look");

      bold.setTextRenderMode(PdfContentByte.

TEXT_RENDER_MODE_FILL_STROKE, 0.5f, new Color(0x0c, 0x00, 0x00));

            document.add(bold);

            document.close();

  }

}

The output of the program is given below:
