      • getDataBufferData

        private static final java.lang.Object getDataBufferData​(java.awt.image.DataBuffer db)
        Returns the data array from the DataBuffer.

      • getContiguousData

        private static final java.awt.image.Raster getContiguousData​(java.awt.image.RenderedImage im,
                                                             java.awt.Rectangle region)
        Returns a contiguous Raster of data over the specified Rectangle. If the region is a sub-region of a single tile, then a child of that tile will be returned. If the region overlaps more than one tile and has 8 bits per sample, then a pixel interleaved Raster having band offsets 0,1,... will be returned. Otherwise the Raster returned by im.copyData(null) will be returned.

      • reformat

        private static void reformat​(java.awt.image.Raster source,
                             int[] sourceBands,
                             int subsampleX,
                             int subsampleY,
                             java.awt.image.WritableRaster dst)
        Subsamples and sub-bands the input Raster over a sub-region and stores the result in a WritableRaster.
        Parameters:
        src - The source Raster
        sourceBands - The source bands to use; may be null
        subsampleX - The subsampling factor along the horizontal axis.
        subsampleY - The subsampling factor along the vertical axis. in which case all bands will be used.
        dst - The destination WritableRaster.
        Throws:
        java.lang.IllegalArgumentException - if source is null or empty, dst is null, sourceBands.length exceeds the number of bands in source, or sourcBands contains an element which is negative or greater than or equal to the number of bands in source.
