DESCRIPTION
vand logically ANDs two images pixel by pixel.

For each corresponding pair of pixels from the input images, the corresponding output pixel is assigned the value of the first input image if both input pixels are not zero. If one of the pixels is zero, the output pixel will be zero.

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
vand -i1 input.image1 -i2 input.image2 -o output.image

This command logically ANDs input.image1 with input.image2 and stores the result in output.image.
