Constructor Detail

MultiLevelImage

protected MultiLevelImage(javax.media.jai.ImageLayout layout,
                          Vector sources,
                          Map properties)

Constructs a new MultiLevelImage. Calls the

Parameters:

layout - The layout of this image or null.

sources - The immediate sources of this image or null.

properties - A Map containing the properties of this image or null.

Method Detail

getTile

public final Raster getTile(int x,
                            int y)

Specified by:

getTile in interface RenderedImage

Specified by:

getTile in class javax.media.jai.PlanarImage

getData

public final Raster getData()

Specified by:

getData in interface RenderedImage

Overrides:

getData in class javax.media.jai.PlanarImage

getData

public final Raster getData(Rectangle rect)

Specified by:

getData in interface RenderedImage

Overrides:

getData in class javax.media.jai.PlanarImage

copyData

public final WritableRaster copyData(WritableRaster raster)

Specified by:

copyData in interface RenderedImage

Overrides:

copyData in class javax.media.jai.PlanarImage

dispose

public void dispose()

Provides a hint that an image will no longer be accessed from a reference in user space. The results are equivalent to those that occur when the program loses its last reference to this image, the garbage collector discovers this, and finalize is called. This can be used as a hint in situations where waiting for garbage collection would be overly conservative.

The results of referencing an image after a call to dispose() are undefined.

Overrides shall call super.dispose() in a final step.

dispose in class javax.media.jai.PlanarImage
