I am not familiar with "imagePanel ". What framework are you using?

[Macro 90G]

I am using 'JFrame' and i would like to know how to use ImagePanel, ImageFileManage r, OFImage and ImageViewer to set photo as a background of a GUI.

I only know of JFrame being a class in the core set of Java SE classes; are all
the Image* classes your own or from a third part library? If so you need to consult
their API documentation for their use because they are not part of the Java SE
core library.

kind regards,

There are a number of ways to get a background image. My favourite way is a bit of a cheat, since I define a Border that draws the image. I like this approach since it doesn't involve subclassing any JComponent type.

[CODE=Java]import java.awt.*;
import java.awt.image. *;
import javax.swing.bor der.*;

public class CentredBackgrou ndBorder implements Border {
private final BufferedImage image;

public CentredBackgrou ndBorder(Buffer edImage image) {
this.image = image;
}

public void paintBorder(Com ponent c, Graphics g, int x, int y, int width, int height) {
int x0 = x + (width-image.getWidth( ))/2;
int y0 = y + (height-image.getHeight ())/2;
g. drawImage(image , x0, y0, null);
}

public Insets getBorderInsets (Component c) {
return new Insets(0,0,0,0) ;
}

public boolean isBorderOpaque( ) {
return true;
}
}
[/CODE]

[CODE=Java]import java.awt.*;
import java.io.*;
import java.net.URL;
import javax.imageio.* ;
import javax.swing.*;
import javax.swing.bor der.*;

public class BackgroundBorde rExample {
public static void main(String[] args) throws IOException {
JFrame.setDefau ltLookAndFeelDe corated(true);
JFrame f = new JFrame("Backgro undBorderExampl e");
f.setDefaultClo seOperation(JFr ame.EXIT_ON_CLO SE);
JTextArea area = new JTextArea(24,80 );
area.setForegro und(Color.WHITE );
area.setOpaque( false);
area.read(new FileReader(new File("Backgroun dBorderExample. java")), null);
final JScrollPane sp = new JScrollPane(are a);
sp.setBackgroun d(Color.BLACK);
sp.getViewport( ).setOpaque(fal se);
f.getContentPan e().add(sp);
f.setSize(600,4 00);
f.setLocationRe lativeTo(null);
f.setVisible(tr ue);

String url = "http://blogs.sun.com/jag/resource/JagHeadshot.jpg ";
final Border bkgrnd = new CentredBackgrou ndBorder(ImageI O.read(new URL(url)));
Runnable r = new Runnable() {
public void run() {
sp.setViewportB order(bkgrnd);
sp.repaint();
}
};
SwingUtilities. invokeLater(r);
}
}
[/CODE]

In the above example (where orange really isn't my best colour) I used the JScrollPane method setViewportBord er. For other containers, you typically use setBorder.
