DESCRIPTION
     vfloor clips the lower levels of an image to a constant,
     specified value. The result image is of the same data type
     as the input image. Any pixel with value less than that
     specfied in the -l argument is given the value of that argu-
     ment.

REQUIRED ARGUMENTS
     -i     type: infile
            desc: input image

     -o     type: outfile
            desc: resulting output image

     -l     type: float
            desc: floor level

OPTIONAL ARGUMENTS
     none

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

     All pixels in input.image with value less than 10 are given
     value 10.  All pixels greater than 10 keep the same value.
     Output is stored in output.image.
