.SH NAME
QccWAVSubbandPyramidIntRasterScan, QccWAVSubbandPyramidIntInverseRasterScan \- 
raster scanning of integer-valued subband-pyramid subbands
.SH SYNOPSIS
.B #include "libQccPack.h"
.sp
.BI "int QccWAVSubbandPyramidIntRasterScan(const QccWAVSubbandPyramidInt *" subband_pyramid ", QccVectorInt " scanned_coefficients );
.br
.BI "int QccWAVSubbandPyramidIntInverseRasterScan(QccWAVSubbandPyramidInt *" subband_pyramid ", const QccVectorInt " scanned_coefficients );
.SH DESCRIPTION
.BR QccWAVSubbandPyramidIntRasterScan()
performs a raster scan on each subband in
.IR subband_pyramid ,
returning the scanned coefficients in
.IR scanned_coefficients .
Each subband is scanned from upper left to lower right, and the subbands
are scanned starting with the baseband and going to the highest-frequency
subbands.
.LP
.BR QccWAVSubbandPyramidIntInverseRasterScan()
reverses the raster-scan process, filling
.I subband_pyramid
with the cofficients from
.IR scanned_coefficients .
.LP
For both of these routines,
.I subband_pyramid
and
.I scanned_coefficients
must be allocated before the routines are called.
.SH "RETURN VALUES"
These routines
return 0 on success and 1 on error.
