public Object getProperty (String name, ImageObserver observer)

Overriding: java.awt.Image

Returns a property of the image by name. Individual property names are defined by the various image formats. If a property is not defined for a particular image, this method returns the UndefinedProperty field. If the properties for this image are not yet known, then this method returns null and the ImageObserver object is notified later. The property name "comment" should be used to store an optional comment that can be presented to the user as a description of the image, its source, or its author.

Parameters:

name the property name

observer the ImageObserver that receives notification regarding image information

Returns: an Object that is the property referred to by the specified name or null if the properties of this image are not yet known.

public String[] getPropertyNames ()

public ImageProducer getSource ()

Overriding: java.awt.Image

Returns the object that produces the pixels for the image.

Returns: the ImageProducer that is used to produce the pixels for this image.

ImageProducer

public Vector<RenderedImage> getSources ()

Implementing: java.awt.image.RenderedImage

Returns a Vector of RenderedImage objects that are the immediate sources, not the sources of these immediate sources, of image data for this BufferedImage. This method returns null if the BufferedImage has no information about its immediate sources. It returns an empty Vector if the BufferedImage has no immediate sources.

Returns: a Vector containing immediate sources of this BufferedImage object's image date, or null if this BufferedImage has no information about its immediate sources, or an empty Vector if this BufferedImage has no immediate sources.

public Raster getTile (int tileX, int tileY)

Implementing: java.awt.image.RenderedImage

Returns tile (tileX, tileY). Note that tileX and tileY are indices into the tile array, not pixel locations. The Raster that is returned is live, which means that it is updated if the image is changed.

Parameters:

Parameters:

tileX the x index of the tile

tileY the y index of the tile
