All known Subclasses: com.sun.media.jai.opimage.StreamImage, javax.media.jai.WritableRenderedImageAdapter, javax.media.jai.AttributedImage,
| RenderedImageAdapter | | public class RenderedImageAdapter extends PlanarImage (Code) | | A PlanarImage wrapper for a non-writable
RenderedImage. The tile layout, sample model, and so forth
are preserved. Calls to getTile(), getData(),
and copyData() are forwarded to the image being adapted.
The set of properties available on the image will be a combination of
those defined locally via setProperty() and those defined
on the source image with the local properties taking precedence. No
PropertySourceChangeEvent will be generated as a result of
changes to the property set of the source image.
From JAI's point of view, this image is a PlanarImage of
unknown type, with no sources. The source image is assumed to be
immutable. If the RenderedImage source implements
WritableRenderedImage, a
WritableRenderedImageAdapter should be used.
The methods are marked 'final' in order to allow dynamic inlining to
take place. This should eliminate any performance penalty associated with
the use of an adapter class.
Since the methods of this class all derive from
PlanarImage, they are not commented in detail.

| Field Summary | |
| protected RenderedImage | theImage
The RenderedImage being adapted. |
| Constructor Summary | |
| public | RenderedImageAdapter(RenderedImage im)
Constructs a RenderedImageAdapter. |
| Method Summary | |
| final public WritableRaster | copyData(WritableRaster raster)
Forwards call to the true source. | | final public Raster | getData()
Forwards call to the true source. | | final public Raster | getData(Rectangle rect)
Forwards call to the true source. | | final public Object | getProperty(String name)
Retrieves the property from those set locally on the image or,
if the property is not available locally, the call is forwarded to
the true source. | | final public Class | getPropertyClass(String name)
Returns the class expected to be returned by a request for
the property with the specified name. | | final public String[] | getPropertyNames()
Retrieves a list of property names recognized by this image. | | final public Raster | getTile(int x, int y)
Forwards call to the true source unless the specified tile indices
refer to a tile which does not overlap the image bounds in which
case null is returned. | | final public RenderedImage | getWrappedImage()
Returns the reference to the external RenderedImage
originally supplied to the constructor. | | static String[] | mergePropertyNames(String[] localNames, String[] sourceNames)

taking precedence. |
| theImage | | protected RenderedImage theImage(Code) | | The RenderedImage being adapted.
|
| RenderedImageAdapter | | public RenderedImageAdapter(RenderedImage im)(Code) | | Constructs a RenderedImageAdapter.
Parameters:
im - a RenderedImage to be `wrapped' as a PlanarImage.
throws:
IllegalArgumentException - if im isnull. |
| copyData | | final public WritableRaster copyData(WritableRaster raster)(Code) | | Forwards call to the true source.
|
| getData | | final public Raster getData()(Code) | | Forwards call to the true source.
|
| getData | | final public Raster getData(Rectangle rect)(Code) | | Forwards call to the true source.
|
| getProperty | | final public Object getProperty(String name)(Code) | | Retrieves the property from those set locally on the image or,
if the property is not available locally, the call is forwarded to
the true source.
exception:
IllegalArgumentException - if nameis null. |
| getPropertyClass | | final public Class getPropertyClass(String name)(Code) | | Returns the class expected to be returned by a request for
the property with the specified name. If this information
is unavailable, null will be returned.
exception:
IllegalArgumentException - if nameis null. The Class expected to be return by arequest for the value of this property or null.
since:
JAI 1.1 |
| getPropertyNames | | final public String[] getPropertyNames()(Code) | | Retrieves a list of property names recognized by this image.
The locally defined property names are combined with those derived
from the true source.
|
| getTile | | final public Raster getTile(int x, int y)(Code) | | Forwards call to the true source unless the specified tile indices
refer to a tile which does not overlap the image bounds in which
case null is returned.
|
| getWrappedImage | | final public RenderedImage getWrappedImage()(Code) | | Returns the reference to the external RenderedImage
originally supplied to the constructor.
since:
JAI 1.1.2 |
| mergePropertyNames | | static String[] mergePropertyNames(String[] localNames, String[] sourceNames)(Code) | | Merge the Strings in the two arrays with the local names
taking precedence. Comparison is performed independent of case. Both
parameters may be null.
The merged name arrays or null. |
