Method Detail

paint

public void paint(Component component,
                  Graphics g,
                  int x,
                  int y,
                  int width,
                  int height)
Paints an area of a component. The area should be painted the same way as for direction Direction.RIGHT without any flipping.

Parameters:
component - the component to paint on
g - the graphics to paint on
x - the x-coordinate
y - the y-coordinate
width - the width
height - the height

paint

public void paint(Component component,
                  Graphics g,
                  int x,
                  int y,
                  int width,
                  int height,
                  Direction direction,
                  boolean horizontalFlip,
                  boolean verticalFlip)
Paints an area in a specific direction and optinally flipped horizontally and/or vertically. The flips are performed before the rotation is applied.

Parameters:
component - the component to paint on
g - the graphics to paint on
x - the x-coordinate
y - the y-coordinate
width - the width
height - the height
direction - the direction, Direction.RIGHT is the normal direction
horizontalFlip - flip the painted graphics horizontally
verticalFlip - flip the painted graphics vertically

public boolean isOpaque(Component component)
Returns true if this painter paints the entire area with an opaque color.

Parameters:
component - the component to paint on
Returns:
true if this painter paints the entire area with an opaque color

getColor

public Color getColor(Component component)
Returns an approximate average color of the pixels painted by this painter.

Parameters:
component - the component to paint on
Returns:
an approximate average color of the pixels painted by this painter
