  • Constructor Details

    • MultiLevelImage

      protected MultiLevelImage(javax.media.jai.ImageLayout layout, MultiLevelSource levelSource, Map properties)
      Constructs a new MultiLevelImage.
      Parameters:
      layout - The layout of this image or null.
      levelSource - The level source of this image.
      properties - A Map containing the properties of this image or null.

  • Method Details

    • getTile

      public final Raster getTile(int x, int y)
      Specified by:
      getTile in interface RenderedImage
      Overrides:
      getTile in class javax.media.jai.OpImage

    • 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.

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