vxor(1)                      Khoros                       vxor(1)

PROGRAM
     vxor - Exclusive OR two images pixel by pixel.

SYNTAX
     vxor

     -i1            first input image

     -i2            second input image

     -o             resulting output image

     [-V]           Gives the version for vxor

     [-U]           Gives the usage for vxor

     [-P]           Prompts for command line options

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

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

DESCRIPTION
     vxor computes the logical exclusive OR between two images
     pixel by pixel.

     If the input image pixels are either both zero or both
     nonzero, then the corresponding output pixel is set to zero.
     Otherwise, the output pixel is assigned the value of the
     nonzero input pixel.

     The input images may be of the same or different data types.
     If the input images are of different data types, then both
     input images will be upcast to the highest input image data
     type.  The output image data type will be the same as that
     of the highest data type of the input images.

REQUIRED ARGUMENTS
     -i1    type: infile
            desc: first input image

     -i2    type: infile
            desc: second input image

     -o     type: outfile
            desc: resulting output image

OPTIONAL ARGUMENTS
     none

EXAMPLES
     vxor -i1 input.image1 -i2 input.image2 -o output.image

     This command takes the exclusive OR of input.image1 and
     input.image2 and stores the result in output.image.

RESTRICTIONS
     vxor will not operate on transform data storage type viff
     files.
