Constructor Detail

PosPutImageOnScreen

Constructor. No passed in parameters. Creates a new ImageIcon object and sets it as the JLabels' icon

Method Detail

paintComponent

public void paintComponent(Graphics g)

Overrides:

paintComponent in class JComponent

showBufferedImage

public void showBufferedImage(BufferedImage pBufferedImageToDrawOn)

Call this method and pass in the changed BufferedImage to show on the screen. Here the passed in BufferedImage is set as the JLabel's icon, which forces a screen update. Note that a new BufferedImage is not created for each page node clicked in the tree or zoom change, because the some one original BufferedImage is reused over and over and over again by blanking it out by drawing a white rectangle on the whole image, then re-parsing the PCL stream from the beginning and rendering/drawing the PCL of the tree node page just clicked on, or if the same PCL page as before, but changing the zoom in any way, then re-rending the same PCL but doing the scaling and positioning to make everything bigger or smaller and drawn at the adjusted (x,y) and (width, height) for that zoom factor. This way, no more memory is being grabbed to draw the next PCL page or zoom change. Howard 10/11/06

showUpdatingImageVisualCue

finishedUpdatingImage

public void finishedUpdatingImage()

freeUpMemory

public void freeUpMemory()

When the user is done with this rendering session, then free up memory
