Constructor Detail

DrawImage

public DrawImage(java.awt.Image image,
                 int x,
                 int y)

Returns Fill with given image at given location.

Parameters:

image - the specified image to be drawn

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

paintOperation

public void paintOperation(java.awt.Graphics2D graphics)

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

Specified by:

paintOperation in class GraphicsOperation

Parameters:

graphics - graphics context to use for painting

getBounds

public java.awt.Rectangle getBounds()

Returns bounding box of the element. If the element is unbounded then this method returns null.

Specified by:

getBounds in interface DrawingElement

Returns:

bounding box of the element or null is the element is unbounded

getBounds2D

public java.awt.geom.Rectangle2D getBounds2D()

Returns high precision bounding box of the element. If the element is unbounded then this method returns null.

Specified by:

getBounds2D in interface DrawingElement

Returns:

high precision bounding box of the element or null of the element is unbounded

intersects

public boolean intersects(java.awt.geom.Rectangle2D rectangle)

Tests if the element intersects with the given rectangle.

Specified by:

intersects in interface DrawingElement

Parameters:

rectangle - rectangle to be cheched for intersection

Returns:

true if the element intersects with the given rectangle; false otherwase

contains

public boolean contains(java.awt.geom.Point2D point)

Tests if the element containes given point.

Specified by:

contains in interface DrawingElement

Parameters:

point - to be checked

Returns:

true if the element contains given point; false otherwise

imageUpdate

public boolean imageUpdate(java.awt.Image img,
                           int infoflags,
                           int x,
                           int y,
                           int width,
                           int height)

This method is called when information about an image which was previously requested using an asynchronous interface becomes available.

Specified by:

imageUpdate in interface java.awt.image.ImageObserver

Parameters:

img - the image being observed

Returns:

false if the infoflags indicate that the image is completely loaded; true otherwise
