.SH NAME
QccWAVSubbandPyramidIntDWT, QccWAVSubbandPyramidIntInverseDWT \- 
separable 2D discrete wavelet transform and inverse transform
for integer-valued subband-pyramid data
.SH SYNOPSIS
.B #include "libQccPack.h"
.sp
.BI "int QccWAVSubbandPyramidIntDWT(QccWAVSubbandPyramidInt *" subband_pyramid ", int " num_levels ", const QccWAVWavelet *" wavelet );
.br
.BI "int QccWAVSubbandPyramidIntInverseDWT(QccWAVSubbandPyramidInt *" subband_pyramid ", const QccWAVWavelet *" wavelet );
.SH DESCRIPTION
.B QccWAVSubbandPyramidIntDWT()
calls
.BR QccWAVWaveletDWT2DInt (3)
to perform a separable 2D discrete wavelet transform (DWT) on the
.I matrix
field of
.IR subband_pyramid .
.I num_levels
is the number of levels (scales) of decomposition to perform;
the 
.I num_levels
field of
.I subband_pyramid
is set to
.IR num_levels .
The
.IR origin_row ,
.IR origin_col ,
.IR subsample_pattern_row ,
and
.IR subsample_pattern_col
parameters as needed for
.BR QccWAVWaveletDWT2DInt (3)
are extracted from the corresponding fields of
.IR subband_pyramid .
.LP
.BR QccWAVSubbandPyramidIntInverseDWT()
calls
.BR QccWAVWaveletInverseDWT2DInt (3)
to perform a separable 2D inverse DWT on the
.I matrix
field of
.IR subband_pyramid .
The number of levels of the inverse transform is retrieved from the
.I num_levels
field of
.IR subband_pyramid ;
.I num_levels
is set to 0 upon return of
.BR QccWAVSubbandPyramidIntInverseDWT().
.SH "RETURN VALUES"
These routines
return 0 on success and 1 on error.
