NAME
osiv_getvects - retrieves vectors from osiv data file
SYNOPSIS
osiv_getvects -f frame_num [-o
output_file] [-p format] file
DESCRIPTION
osiv_getvects is a program for
extracting the vectors from an osiv data file. If the file is "-",
data will be read from stdin. However, since osiv_getvects
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
- -f - frame number
- Frame number, as specified in the original osiv call.
- -o - output file
- This is a text file whose format is specified by the "-p"
option.
- -p - print format
- osiv_getvects traverses through the window grid making a
call to printf() for every vector. The x position is specified with
`%x', the y position with `%y', the x displacement with `%u', and
the y displacement with `%v'. The default is `%.0x, %.0y; %+.8u,
%+.8v\n'.
