    • getLevelImageSupport

      protected LevelImageSupport getLevelImageSupport()

    • createNoDataRaster

      protected NoDataRaster createNoDataRaster(double noDataValue)
      Creates a new raster containing solely no-data (non-interpretable data, missing data) samples. The raster's data buffer is filled with the given no-data value.

      The raster's origin is (0, 0). In order to translate the raster, use Raster.createTranslatedChild(int x, int y).

      Parameters:
      noDataValue - The no-data value used to fill the data buffer of the raster created.
      Returns:
      the raster created.

    • computeRect

      protected final void computeRect(Raster[] sources, WritableRaster dest, Rectangle destRect)
      Empty implementation. Used to prevent clients from overriding it, since they shall implement OpImage.computeRect(javax.media.jai.PlanarImage[], java.awt.image.WritableRaster, java.awt.Rectangle).
      Overrides:
      computeRect in class javax.media.jai.OpImage
      Parameters:
      sources - The sources.
      dest - The destination raster.
      destRect - The destination rectangle.
