NAME
osiv_getmap - retrieves correlation map from osiv data
file
SYNOPSIS
osiv_getmap -f frame -w
window [-o output] [-p format] file
DESCRIPTION
osiv_getmap is a program for extracting
a correlation map from an osiv data file. If the file is "-", data
will be read from stdin. However, since osiv_getmap requires
random access to the file this is rarely useful. Similarly, if the
output file is omitted or set to "-", data will be written to
stdout.
OPTIONS
- -o - output file
- This is a text file whose format is specified by the "-p"
option.
- -f - frame number
- The frame number is specified as in the original osiv
call.
- -w - window number
- The window number is given in "row-major" format. In other
words, the index is c+r*nc, where c is the column, r is the row,
and nc is the number of columns in the grid.
- -p - print format
- osiv_getmap traverses through the map making a call to
printf() for every element. The x displacement is specified with
`%u', the y displacement with `%v', and the correlation value with
`%e'. The default is `%.0u %.0v %+.4e\n'.
