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. SEE ALSO
