Constructor Detail

ForwCompTransfSpec

public ForwCompTransfSpec(int nt,
                  int nc,
                  byte type,
                  AnWTFilterSpec wfs,
                  ParameterList pl)

Constructs a new 'ForwCompTransfSpec' for the specified number of components and tiles, the wavelet filters type and the parameter of the option 'Mct'. This constructor is called by the encoder. It also checks that the arguments belong to the recognized arguments list.

This constructor chose the component transformation type depending on the wavelet filters : RCT with w5x3 filter and ICT with w9x7 filter. Note: All filters must use the same data type.

Parameters:

nt - The number of tiles

nc - The number of components

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

wfs - The wavelet filter specifications

pl - The ParameterList
