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.
