x - the x coordinate

y - the y coordinate

Method Detail

setImage

public void setImage(java.awt.Image image)

Sets image to be drawn.

Parameters:

image - the specified image to be drawn

getImage

public java.awt.Image getImage()

Gets image to be drawn.

Returns:

image to be drawn

setX

public void setX(int x)

Sets X coordinate of the image.

Parameters:

x - the x coordinate

getX

public int getX()

Returns X coordinate of the image.

Returns:

the x coordinate of the image

setY

public void setY(int y)

Sets Y coordinate of the image.

Parameters:

y - the y coordinate

getY

public int getY()

Returns X coordinate of the image.

Returns:

the x coordinate of the image

setObserver

public void setObserver(java.awt.image.ImageObserver observer)

Sets the ImageObserver used by this operation.

Parameters:

observer - an ImageObserver object

getObserver

public java.awt.image.ImageObserver getObserver()

Returns the ImageObserver used by this operation.

paintOperation

public void paintOperation(java.awt.Graphics2D graphics)

Performs drawing operation. This implementation invokes graphics.fill ().

Specified by:

paintOperation in class GraphicsOperation

Parameters:

graphics - graphics context to use for painting

getShapeOfOperation

public java.awt.Shape getShapeOfOperation()

Returns shape of the area updated by this operation.

Specified by:

getShapeOfOperation in class GraphicsOperation

Returns:

the shape of updated area

equals

public boolean equals(java.lang.Object object)

Checks whether two draw image operations are equal. The result is true if and only if the argument is not null and is a DrawImage object that has the same attributes as this DrawImage.

Overrides:

equals in class GraphicsOperation

Parameters:

object - the Object to compare with this DrawImage

Returns:

true if the objects are equal; false otherwise.

hashCode

public int hashCode()

Returns the hashcode for this draw image operation.

Overrides:

hashCode in class GraphicsOperation

Returns:

a hash code for this draw image operation.
