Hi,
I am kind of new to java...
I found this JApplet code which writes text to a image file...But i want to run this without using the applet...How can i covert this JApplet to an old fashion java Application...
I would appreciate if someone can show me how... I am posting the code below.....You will need JAI API...
Thanks in advance....
======================================================================

import java.awt.*;
import java.awt.event.*;
import com.sun.image.codec.jpeg.*;
import com.sun.media.jai.codec.*;
import javax.media.jai.*;
import java.awt.image.BufferedImage;
import java.awt.image.RenderedImage;
import java.awt.image.DataBuffer;
import java.awt.geom.GeneralPath;
import java.io.*;
import javax.swing.*;
import java.awt.image.renderable.ParameterBlock;

public class JPEGJai extends JApplet {
// private static Image img;
public static final String DEFAULT_FILE = "blank.jpg";
private static RenderedImage img;
public void init() {
setBackground(Color.white);
String fileName = DEFAULT_FILE;
// Read the image from the designated path.
System.out.println("load image from '" + fileName+"'");
img = (RenderedImage)JAI.create("fileload", fileName);
}

public void paint(Graphics g) {
Graphics2D g2 = (Graphics2D) g;
Dimension d = getSize();
g2.setBackground(getBackground());
g2.clearRect(0, 0, d.width, d.height);
g2.setRenderingHint(RenderingHints.KEY_ANTIALIASING,
RenderingHints.VALUE_ANTIALIAS_ON);
g2.setRenderingHint(RenderingHints.KEY_RENDERING,
RenderingHints.VALUE_RENDER_QUALITY);
int w = d.width;
int h = d.height;

RenderedImageAdapter ria = new RenderedImageAdapter(img);
BufferedImage bi = ria.getAsBufferedImage();
Graphics2D big = bi.createGraphics();
big.setFont(new Font("Dialog", Font.PLAIN, 20));
big.setColor(Color.black);
big.drawString("Data/Time Created:" + new java.util.Date(), 80, 210);
big.drawString("POLICY NUMBER: 1711215 NAME OF CALLER: BENEFICIARY", 80, 230);
big.drawString("Requested: Loan Request Current Loan Value: $0.00", 80, 270);

g2.drawImage(bi, 0, 0, this);
try {
File file = new File("test.tiff");
FileOutputStream out = new FileOutputStream(file);

TIFFEncodeParam params = new TIFFEncodeParam();
params.setCompression(TIFFEncodeParam.COMPRESSION_NONE);
ImageEncoder encoder = ImageCodec.createImageEncoder("TIFF",out, params);
if(encoder == null) {
System.out.println("imageEncoder is null");
System.exit(0);
}
encoder.encode(bi);

} catch (Exception ex) {
g2.setColor(Color.red);
g2.drawString("write permissions on images/test.jpg?", 5, h*2-5);
}

}

public static void main(String argv[]) {
final JPEGJai demo = new JPEGJai();
demo.init();
JFrame f = new JFrame("JAI Demo - JPEGJai");
f.addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent e) {System.exit(0);}
});
f.getContentPane().add("Center", demo);
f.pack();
f.setSize(new Dimension(400,300));
f.show();
}
}
