Constructor Detail

CompTransfSpec

public CompTransfSpec(int nt,
                      int nc,
                      byte type)

Constructs an empty 'CompTransfSpec' with specified number of tile and components. This constructor is called by the decoder. Note: The number of component is here for symmetry purpose. It is useless since only tile specifications are meaningful.

Parameters:

nt - Number of tiles

nc - Number of components

type - the type of the specification module i.e. tile specific, component specific or both.

Method Detail

isCompTransfUsed

public boolean isCompTransfUsed()

Check if component transformation is used in any of the tiles. This method must not be used by the encoder.

Returns:

True if a component transformation is used in at least on tile.
