Constructor Detail

QuantStepSizeSpec

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

Constructs an empty 'QuantStepSizeSpec' with specified number of tile and components. This constructor is called by the decoder.

Parameters:

nt - Number of tiles

nc - Number of components

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

QuantStepSizeSpec

public QuantStepSizeSpec(int nt,
                 int nc,

                 J2KImageWriteParamJava wp,
                 String values)

Constructs a new 'QuantStepSizeSpec' for the specified number of components and tiles and the arguments of "-Qstep" option.

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.
