PROGRAM
     vnot - Compliment an image by subtracting pixel values from
     a constant.

SYNTAX
     vnot

     -i             input image

     -o             resulting output image

     -l             level to subtract input image from

     [-V]           Gives the version for vnot

     [-U]           Gives the usage for vnot

     [-P]           Prompts for command line options

     [-A [file1]]   Creates the answer file called vnot.ans or
                    file1

     [-a [file1]]   Uses vnot.ans or file1 as the answer file

DESCRIPTION
     Compliment an image by subtracting pixel values from a con-
     stant.  A constant value of 255 will invert a byte (unsigned
     character) image.

REQUIRED ARGUMENTS
     -i     type: infile
            desc: input image

     -o     type: outfile
            desc: resulting output image

     -l     type: float
            desc: level to subtract input image from

OPTIONAL ARGUMENTS
     none

EXAMPLES
     vnot -i input.image -o output.image -l 10

     This subtracts each pixel in input.image from 10 and places
     the result in output.image.

RESTRICTIONS
     vnot will not operate on COMPLEX or transform data storage
     type images.
