Examples of javax.media.jai.RenderedImageAdapter

javax.media.jai.RenderedImageAdapter
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. @see PlanarImage @see WritableRenderedImageAdapter @see java.awt.image.RenderedImage @see java.awt.image.WritableRenderedImage
