      public nom.tam.image.compression.tile.TileCompressionOperation setDimensions(int dataOffset, int width, int height)
      Specified by:
      setDimensions in interface ITileOperation
      Overrides:
      setDimensions in class AbstractTileOperation

    • setWholeImageCompressedBuffer

      protected void setWholeImageCompressedBuffer(ByteBuffer compressed)
      set the buffer that describes the whole compressed image and let the tile create a slice of it from the position where the tile starts in the whole image. Attention this method is not thread-safe because it changes the position of the buffer parameter. This buffer is just as big as the image buffer but will be reduced to the needed size as a last step of the Compression.
      Parameters:
      compressed - the buffer that describes the whole image.
