#3117 — Spreading an image to the

  To: comp.lang.java.gui
Hello

I found a java code allowing to display an image in a JPanel in 2
ways : either by centering the image or by creating a mosaic picture
of this image ;
I would rather be interested in having this image displayed once and
spreaded to the width and the hight of the JPanel (and this, each time
the JPanel size changes)

anyone has an idea ?

thanks in advance for your suggestions

Jean-Marie


public class JPanelImageBg extends JPanel
{
    private int mode;
    private TexturePaint texture;
    private BufferedImage bufferedImage;

    public static final int CENTER = 0;
    public static final int MOSAIC = 1;

    public JPanelImageBg( String fileName, int mode )
    {
        super();
        setLayout(new BoxLayout(this, BoxLayout.Y_AXIS));

        this.mode = mode;
        this.bufferedImage =
this.toBufferedImage(Toolkit.getDefaultToolkit().getImage(fileName));
        this.texture = new TexturePaint(bufferedImage,new Rectangle(0,
0, bufferedImage.getWidth(), bufferedImage.getHeight()));
    }

    public void paintComponent(Graphics g)
    {
        super.paintComponent(g);
        switch( mode )
        {    case CENTER :
                Graphics2D g2d = (Graphics2D)g;
                g2d.setPaint(texture);
                g2d.fillRect(0, 0, getWidth(), getHeight() );
                break;
            case MOSAIC :
                g.setColor(this.getBackground());
                g.fillRect(0,0,getWidth(), getHeight() );
             g.drawImage(bufferedImage,(getWidth()-
bufferedImage.getWidth())/2,(getHeight()-bufferedImage.getHeight())/
2,null);
                break;
            default :
                super.paintComponents(g);
        }
    }
    private BufferedImage toBufferedImage(Image image)
    {    image = new ImageIcon(image).getImage();

        BufferedImage bufferedImage = new
BufferedImage( image.getWidth(null), image.getHeight(null),
BufferedImage.TYPE_INT_RGB);
        Graphics g = bufferedImage.createGraphics();

        g.setColor(Color.white);
        g.fillRect(0, 0, image.getWidth(null),
        image.getHeight(null));
        g.drawImage(image, 0, 0, null);
        g.dispose();
        return bufferedImage;
    }

}

<code snipped>

g.drawImage(..)

there are many drawImage methods in the Graphics class.
have a look at the docs, you may find exactly what you're after.

there is no doubt about that ;
but if someone has a more accurate answer,
that would help me : perhaps using AffineTransform
is the solution...

Is it just me, or is the code for CENTER and MOSAIC reversed?
