    Public Properties
     NameDescription
     PropertyReturns the negative support of the high-pass analysis filter. That is the number of taps of the filter in the negative direction.  
     PropertyReturns the positive support of the high-pass analysis filter. That is the number of taps of the filter in the negative direction.  
     PropertyReturns the negative support of the low-pass analysis filter. That is the number of taps of the filter in the negative direction.  
     PropertyReturns the positive support of the low-pass analysis filter. That is the number of taps of the filter in the negative direction.  
     PropertyReturns the type of data on which this filter works, as defined in the DataBlk interface.  
     PropertyReturns 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.  
     PropertyReturns the reversibility of the filter. A filter is considered reversible if it is suitable for lossless coding.  
     PropertyReturns the negative support of the high-pass synthesis filter. That is the number of taps of the filter in the negative direction.  
     PropertyReturns the positive support of the high-pass synthesis filter. That is the number of taps of the filter in the negative direction.  
     PropertyReturns the negative support of the low-pass synthesis filter. That is the number of taps of the filter in the negative direction.  
     PropertyReturns the positive support of the low-pass synthesis filter. That is the number of taps of the filter in the negative direction.

     NameDescription
     MethodReturns true if the wavelet filter computes or uses the same "inner" subband coefficient as the full frame wavelet transform, and false otherwise. In particular, for block based transforms with reduced overlap, this method should return false. The term "inner" indicates that this applies only with respect to the coefficient that are not affected by image boundaries processings such as symmetric extension, since there is not reference method for this.

    The result depends on the length of the allowed overlap when compared to the overlap required by the wavelet filter. It also depends on how overlap processing is implemented in the wavelet filter.
