DisplayJAI

public class DisplayJAI extends JPanel implements MouseListener,MouseMotionListener(Code)

A Java^TM Foundation Classes JPanel which is able to contain an image. The image and its container may have different sizes. The image may also be positioned within the container.

This class extends JPanel in order to support layout management. Image tiling is supported as of version 1.3 of the Java^TM 2 Platform via Graphics2D.drawRenderedImage(RenderedImageAffineTransform) .

This class is not a committed part of the Java^TM Advanced Imaging API per se. It might therefore not be supported by JAI implementations other than that of Sun Microsystems, Inc.

Constructor Summary
public	DisplayJAI() Constructs a `DisplayJAI` and sets its the layout to `null`.
public	DisplayJAI(RenderedImage image) Constructs a `DisplayJAI`, sets its layout to `null`, and sets its displayed image.

Method Summary
public Point	getOrigin() Retrieves the image origin.
public RenderedImage	getSource() Returns the image to be displayed by this panel.
public void	mouseClicked(MouseEvent e) An empty method which should be overridden by subclasses which respond to mouse clicks.

paintComponent

public synchronized void paintComponent(Graphics g)(Code)

Draws the image or fills the panel with a background color.

If the current image is null, the rectangle new Rectangle(0,0, DisplayJAI.getWidth() , DisplayJAI.getHeight() ) is filled with the background color returned by DisplayJAI.getBackground() .

If the current image is non-null, the rectangle returned by Graphics2D.getClipBounds is filled with the background color and the image is drawn using Graphics2D.drawRenderedImage(RenderedImageAffineTransform) at the location ( DisplayJAI.getInsets() .left+originX, DisplayJAI.getInsets() .right+originY).
Parameters:
g - Graphics context in which to paint.

set
public void set(RenderedImage im)(Code)
	Sets a new image to display. The preferred size is set such that its width is the image width plus the left and right insets and its height is the image height plus the top and bottom insets. DisplayJAI.revalidate() and DisplayJAI.repaint() are invoked after all other changes. Parameters: im - The image to display. throws: IllegalArgumentException - if `im` is`null`.

set
public void set(RenderedImage im, int x, int y)(Code)
	Sets a new image to display and its coordinates within the container. The preferred size is set such that its width is the image width plus the left and right insets and its height is the image height plus the top and bottom insets. DisplayJAI.revalidate() and DisplayJAI.repaint() are invoked after all other changes. Parameters: im - The image to display. Parameters: x - image origin abscissa. Parameters: y - image origin ordinate. throws: IllegalArgumentException - if `im` is`null`.

setOrigin
public void setOrigin(int x, int y)(Code)
	Moves the image within it's container. The instance variables `originX` and `originY` are set to the parameter valus `x` and `y`, respectively. DisplayJAI.repaint() is invoked after the origin values are changed. Parameters: x - image origin abscissa. Parameters: y - image origin ordinate.
