NAME

6       osiv_getmap - retrieves correlation map from osiv data file

SYNOPSIS

9       osiv_getmap -f frame -w window [-o output] [-p format] file
10

DESCRIPTION

12       osiv_getmap  is a program for extracting a correlation map from
13       an osiv data file.  If the file is "-", data will be read  from
14       stdin.   However,  since  osiv_getmap requires random access to
15       the file this is rarely useful.  Similarly, if the output  file
16       is omitted or set to "-", data will be written to stdout.

OPTIONS

19       -o - output file
20              This  is  a  text  file whose format is specified by the
21              "-p" option.
22
23       -f - frame number
24              The frame number is specified as in  the  original  osiv
25              call.
26
27       -w - window number
28              The  window  number  is given in "row-major" format.  In
29              other words, the index is c+r*nc, where c is the column,
30              r  is  the  row,  and nc is the number of columns in the
31              grid.
32
33       -p - print format
34              osiv_getmap traverses through the map making a  call  to
35              printf() for every element.  The x displacement is spec‐
36              ified with `%u', the y displacement with `%v',  and  the
37              correlation  value with `%e'.  The default is `%.0u %.0v
38              %+.4e\n'.
