PROGRAM
     vgshot - Corrupts an image uniformly with spikes (noise).

SYNTAX
     vgshot

     -i             input image

     -o             resulting output image

     [-trigger]     trigger input

     [-n]           spikes percentage

     [-V]           Gives the version for vgshot

     [-U]           Gives the usage for vgshot

     [-P]           Prompts for command line options

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

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

DESCRIPTION
     vgshot corrupts an image uniformly with spikes. The percen-
     tage of spikes must be specified by the user. Spike loca-
     tions are determined using a uniformly distributed random
     number generator.

     The trigger input can be used to cause vgshot to re-execute
     when used inside cantata. No image is read from this input.

REQUIRED ARGUMENTS
     -i     type: infile
            desc: input image

     -o     type: outfile
            desc: resulting output image

OPTIONAL ARGUMENTS
     -trigger
            type: infile
            desc: trigger input

     -n     type: float
            desc: spikes percentage
            default: 10
            bounds: 0.000000 < [-n] < 100.000000
