NAME
regionMean, regionXmean, regionYmean - calculate xmeanor ymean of one or more regions
SYNTAX
#include <
xite/region.h>
int regionXmean( IBAND band, region* reg,
int loop, double* xmean );
int regionYmean( IBAND band, region* reg,
int loop, double* ymean );
int regionMean( IBAND band, region* reg,
int loop, double* xmean, double* ymean );
DESCRIPTION
Calculates xmean (ymean) of one or several regions.If "loop" is false, xmean (ymean) of "reg" is measured.If true, the next pointer in reg is followed until nil,and xmean (ymean) of the whole region set is calculated.If "band" is nil, the simple mean of the region iscalculated. If "band" is a band, the pixel valuesare used as weights.
RETURN VALUE
0 => ok
1 => bad pixeltype, accepts only unsigned byte
2 => "reg" points to nil. Area is set to 0.
