SYNOPSIS

       vflip [-hor] [-vert] [-option ...] [infile] [outfile]

DESCRIPTION

       vflip flips images horizontally and/or vertically.

       A horizontal flip exchanges the left and right sides of an image. A vertical flip exchanges the top and bottom.

COMMAND LINE OPTIONS

       vflip 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 flipped images as a Vista data file.
