vistat

vistat(1Vi)															       vistat(1Vi)

NAME

       vistat - report image statistics

SYNOPSIS

       vistat [-option ...] [infile ...] [outfile]

DESCRIPTION

       vistat reports the minimum, maximum, mean, and standard deviation of the pixel values in its input images.

       The  measurements  are  reported  in  the form of a Vista data file containing one statistics attribute per image measured. Each statistics
       attribute, in turn, contains min, max, mean, and std_dev attributes reporting individual measurements. It also contains a name attribute if
       the  corresponding  image  has  one.   Because  these attribute have no binary data associated with them the program's output can be viewed
       directly at a terminal.

COMMAND LINE OPTIONS

       vistat accepts the following options:

       -help	      Prints a message describing options.

       -in infile     Specifies a Vista data file containing the input images.

       -out outfile   Specifies where to write the output statistics as a Vista data file.

       Input and output files can be specified on the command line or allowed to default to the standard input and output streams.
