  Specified by:

  setDimensions in interface ITileOperation

  Overrides:

  setDimensions in class AbstractTileOperation

• setWholeImageCompressedBuffer

  protected void setWholeImageCompressedBuffer​(java.nio.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.
