CONSTRUCTORS

O Surface 
  public Surface(int width,
                 int height)
Creates a Surface.
Parameters:
width - -- width of the surface. If this is negative, it is set to 0
height - -- height of the surface. If this is negative, it is set to 0

METHODS

O size 
  public Dimension size()
Returns the size of the surface (width and height)
Returns:
s Surface dimensions
O finalize 
  protected void finalize() throws Throwable
Called immediately before garbage collection of this object.
Throws: Throwable
Never thrown. See Object.finalize for further information.
Overrides:
finalize in class Object
O setDestinationWindow 
  public void setDestinationWindow(Component c)
Maps a surface to a destination AWT Component window. To display the surface in the Component, call draw.
Parameters:
c - The Component on which to draw the Surface.
See Also:
getDestinationWindow, draw
O getDestinationWindow 
  public Component getDestinationWindow()
Returns the destination AWT Component window for a surface.
Returns:
s The Component the surface is mapped to. Null if surface is not mapped to component.
See Also:

O setBackground 
  public synchronized void setBackground(Image bgIm)
Assigns a default background image to a surface. This overrides the background color.
Parameters:
bgIm - is the Image
O setColor 
  public synchronized void setColor(Image bgIm)
Assigns a default background image to a surface. This overrides the background color.
Parameters:
bgIm - is the Image
O setColor 
  public synchronized void setColor(Color c)
Assigns a default color to a surface. The default color is displayed in a pixel location that is not occupied by displayable data.
Parameters:
c - either null (to clear any existing default color) or the new default color (must be between 0 and 255 when using RGB_CLUT8 style color).

getColor
O getColor 
  public Color getColor()
Returns the current default color for a surface. The default color is displayed in a pixel location that is not occupied by displayable data.
Returns:
s The default color, null if default color has not been set.
See Also:

O draw 
  public synchronized boolean draw()
Draws a surface to its destination AWT Component window.
Returns:
false if draw failed, true otherwise. RA need to document failure conditions
O getFPS 
  public double getFPS()
Get current frame rate, in frames per second
Returns:
current frame rate, in frames per second
