javax.media.jai.TiledImage
| TiledImage | | public class TiledImage extends PlanarImage implements WritableRenderedImage,PropertyChangeListener(Code) | | A concrete implementation of WritableRenderedImage.
TiledImage is the main class for writable images
in JAI. TiledImage provides a straightforward
implementation of the WritableRenderedImage interface,
taking advantage of that interface's ability to describe images
with multiple tiles. The tiles of a
WritableRenderedImage must share a
SampleModel, which determines their width, height, and
pixel format. The tiles form a regular grid, which may occupy any
rectangular region of the plane. Tile pixels the locations of which
lie outside the stated image bounds have undefined values.
The contents of a TiledImage are defined by a
single RenderedImage source provided by means of one of
the set() methods or to a constructor which accepts a
RenderedImage. The set() methods provide
a way to selectively overwrite a portion of a TiledImage,
possibly using a region of interest (ROI).
TiledImage also supports direct manipulation of
pixels by means of the getWritableTile() method. This
method returns a WritableRaster that can be modified directly.
Such changes become visible to readers according to the regular
thread synchronization rules of the Java virtual machine; JAI makes
no additional guarantees. When a writer is finished modifying a
tile, it should call releaseWritableTile(). A
shortcut is to call setData(), which copies a rectangular
region or an area specified by a ROI from a supplied
Raster directly into the TiledImage.
A final way to modify the contents of a TiledImage
is through calls to the object returned by createGraphics().
This returns a Graphics2D object that can be used to draw
line art, text, and images in the usual Abstract Window Toolkit (AWT)
manner.
A TiledImage does not attempt to maintain
synchronous state on its own. That task is left to
SnapshotImage. If a synchronous (unchangeable) view
of a TiledImage is desired, its
createSnapshot() method must be used. Otherwise,
changes due to calls to set() or direct writing of tiles by objects
that call getWritableTile() will be visible.
TiledImage does not actually cause its tiles to be
copied from the specified source until their contents are demanded.
Once a tile has been computed, its contents may be discarded if it can
be determined that it can be recomputed identically from the source.
The lockTile() method forces a tile to be computed and
maintained for the lifetime of the TiledImage.
