SYNOPSIS

vvecs [if=infile] [of=ofile] [-s] [-w]

DESCRIPTION

Vvecs prints some basic statistics for each 2D-vector found in the input file. It is designed to provide some simple statistics from a graph file in vector format (such as that produced by vhist). The results are output as a VisionX text file unless a script compatible format is specified. By default the mean pixel value are printed. Additional values may be computed by options outlined below.
