PROGRAM NAME
vunion - Union of Two Images
DESCRIPTION
vunion
will do the supremum of two input images pixel by pixel.
The two input images must be of the same size and have the same
number of data bands. The input
images may be of the same or different data types. If the input
images are of different data types, then all input images will be
upcast to the highest input image data type. A parameter defining
a constant image can be entered instead of the second image. 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
- -o
-
type: outfile
desc: resulting output image
Mutually Exclusive Group; you must specify ONE of:
- -i2
-
type: infile
desc: second input image
default: {none}
OR
- -c
-
type: integer
desc: sub constant
default: 0
bounds: 0 < [-c] < 255
OPTIONAL ARGUMENTS
none
EXAMPLES
vunion -i1 ball.xv -i2 feath.xv -o outimage.xv
Will do the supremum of image 1 "ball.xv" and image 2 "feath.xv" with the resulting
image written to "outimage.xv".

can be defined for all data types supported by Khoros, but at the moment it has been implemented just for the bit and unsigned char types.
