    Public Properties
     NameDescription
    Public PropertyOverridden. Returns the negative support of the high-pass analysis filter. That is the number of taps of the filter in the negative direction.  
    Public PropertyOverridden. Returns the positive support of the high-pass analysis filter. That is the number of taps of the filter in the negative direction.  
    Public PropertyOverridden. Returns the negative support of the low-pass analysis filter. That is the number of taps of the filter in the negative direction.  
    Public PropertyOverridden. Returns the positive support of the low-pass analysis filter. That is the number of taps of the filter in the negative direction.  
    Public PropertyReturns the type of data on which this filter works, as defined in the DataBlk interface, which is always TYPE_FLOAT for this class. (Inherited from CSJ2K.j2k.wavelet.analysis.AnWTFilterFloat)
    Public PropertyOverridden. Returns the type of filter used according to the FilterTypes interface(W9x7).  
    Public PropertyOverridden. Returns the implementation type of this filter, as defined in this class, such as WT_FILTER_INT_LIFT, WT_FILTER_FLOAT_LIFT, WT_FILTER_FLOAT_CONVOL.  
    Public PropertyOverridden. Returns the reversibility of the filter. A filter is considered reversible if it is suitable for lossless coding.

    Public Methods
     NameDescription
    Public MethodOverloaded. Overridden. The general version of the analyze_hpf() method, it just calls the specialized version. See the description of the analyze_hpf() method of the AnWTFilter class for more details.  
    Public MethodOverloaded. Overridden. The general version of the analyze_lpf() method, it just calls the specialized version. See the description of the analyze_lpf() method of the AnWTFilter class for more details.

    Public MethodOverridden.   
    Public MethodReturns the equivalent high-pass synthesis waveform of a cascade of filters, given the syhthesis waveform of the previous stage. This is the result of upsampling 'in' by 2, and concolving it with the high-pass synthesis waveform of the filter. The length of the returned signal is 2*in_l+hp_l-2, where in_l is the length of 'in' and 'hp_l' is the lengthg of the high-pass synthesis filter.

    The length of the high-pass synthesis filter is getSynHighNegSupport()+getSynHighPosSupport().

This is the result of upsampling 'in' by 2, and concolving it with the low-pass synthesis waveform of the filter. The length of the returned signal is 2*in_l+lp_l-2, where in_l is the length of 'in' and 'lp_l' is the lengthg of the low-pass synthesis filter.

    The length of the low-pass synthesis filter is getSynLowNegSupport()+getSynLowPosSupport().
