voffset(1)                   Khoros                    voffset(1)

PROGRAM
     voffset - Add a specified offset to each pixel in the input
     image.

SYNTAX
     voffset

     -i             input image

     -o             resulting output image

     -x             offset value for image

     [-m]           add operation masking image

     [-V]           Gives the version for voffset

     [-U]           Gives the usage for voffset

     [-P]           Prompts for command line options

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

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

DESCRIPTION
     voffset add a constant to an image,  pixel by pixel with an
     optional operation gating image.

     The optional mask image must be of the same data type and
     size as the input image. A non-zero mask pixel enables the
     output pixel to contain the sum. A zero mask pixel just
     transfers the value of the corresponding pixel in the first
     input image to the output pixel.

REQUIRED ARGUMENTS
     -i     type: infile
            desc: input image

     -o     type: outfile
            desc: resulting output image

     -x     type: float
            desc: offset value for image

OPTIONAL ARGUMENTS
     -m     type: infile
            desc: add operation masking image

EXAMPLES
     voffset -i input.image -o output.image -x 2 -m mask.image

     This adds 2 to each pixel in input.image using mask.image
     and places the result in output.image.

RESTRICTIONS
     voffset will not operate on:
          Complex, and Bit
