image label

[Jude Fawly]

hi,

i am using an image label. images with sizes 200x200 will fit in the label and the whole
display is neat. but when i load an image with width 300 pix for example, the whole display
gets messed up.
How can i be able to load any image size in the image label while keeping the display neat.
if this is not possible, how can i limit the JFileChooser to choose images with 200X200 pixels?

thanks for any help

You could choose to resize images if their sizes are not 200x200.

You can retrieve an Image object from an ImageIcon, scale it and set it again.

May be you could use a home-made image-panel, like this:
(this imagepanel will be the exact size of the image when placed in
an appropriate container)

//file ImagePanel.java
  
import java.awt.*;
import javax.swing.*;
import java.awt.image.*;
 
public class ImagePanel extends JPanel{
 
//members****************************************
protected Image image = null;
protected final int defaultWidth = 300;
protected int width = defaultWidth;
protected int height = defaultWidth;
 
//constructor*************************************
 
public ImagePanel(){
super();
}
 
//getters and setters****************************
 
public String getSizeInfo(){
String RETURN=null;
if (image!=null){
RETURN = image.getWidth(this)+ 
                           " X "+image.getHeight(this);
}else{
RETURN = "no size known";
};
return RETURN;
}
 
public void setImage(Image im){
this.image=im;
if (image!=null){
width = image.getWidth(this);
height = image.getHeight(this);
}else{
width = defaultWidth;
height = defaultWidth;
};
revalidate();
}
 
//overriding stuff********************************************
 
public Dimension getPreferredSize(){
return new Dimension(width,height);
}
 
public Dimension getMaximumSize(){
return getPreferredSize();
        }
 
public void paintComponent(Graphics g){
super.paintComponent(g);
if (image!=null){
Graphics2D g2D = (Graphics2D)g;
g2D.drawImage(image,0,0,(Component)this);
};
}
 
}//end ImagePanel
