SYNTAX

vor

-i1 first input image

-i2 second input image

-o  resulting output image

[-V]
    Gives the version for vor

[-U]

[-P]
    Prompts for command line options

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

[-a [file1]]

DESCRIPTION
vor performs a logical OR between two images.

For each pair of corresponding input pixels in the input images, the corresponding output pixel is assigned the value of the first input image pixel in all cases, except when the first image pixel is zero and the second input image pixel is nonzero. In this case, the output pixel is set to the value of the second input image 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
vor -i1 input.image1 -i2 input.image2 -o output.image

This command performs the OR between input.image1 and input.image2 and stores the result in output.image.
