      • 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

      • 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.

        Overrides:
        dispose in class javax.media.jai.PlanarImage
