      • 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.
