Member Typedef Documentation

typedef int TFilterType

Wavelet filter type. Use OR-ed combination of the following types: WAVE_FILTER_ANALYSIS Analysis filter. WAVE_FILTER_SYNTHESIS Synthesis filter. WAVE_FILTER_LOWPASS Low pass filter. WAVE_FILTER_HIGHPASS High pass filter. WAVE_FILTER_TREE1 Orientation 1 filter (for complex wavelets). WAVE_FILTER_TREE2 Orientation 2 filter (for complex wavelets). Note: Certain filter combinations such as 'WAVE_FILTER_LOWPASS | WAVE_FILTER_HIGHPASS' are not allowed. One may use predefined constants: WAVE_FILTER_ANALYSIS_LOW, WAVE_FILTER_ANALYSIS_HIGH , WAVE_FILTER_SYNTHESIS_LOW, WAVE_FILTER_SYNTHESIS_HIGH ,

Member Function Documentation

virtual const TCoeff* Get (  TFilterType  type  )  const [pure virtual]

Return requested filter. Parameters: type  Requested filter type. See also: TFilterType. Returns: Pointer to the filter data of NULL if filter type not supported. Implemented in CFarras.

virtual int Size (   )  const [pure virtual]

Return the size of the filter (i.e. the support size of the wavelet). Implemented in CFarras.
