Mapping and Analysis CD | WlzImageArithmetic

Usage: WlzImageArithmetic [-o< out file >] [-a] [-d] [-l] [-m] [-s] [-h] [< in object 0 >] [< in object 1 >]


Options:
      -o Output file name.
      -a Add the object's grey values.
      -d Divide the grey values of the 1st object by those of the 2nd.
      -g Vector magnitude of horizontal and vertical component objects
      -l Compute the modulus of the grey values of the 1st object wrt
            those of the 2nd.
      -m Multiply the object's grey values.
      -s Subtract the grey values of the 2nd object from those of the 1st.
      -n Normalises the output object to the range of the imput objects.
      -N Normalises the output objects to the range [0-255].
      -h Help, prints this usage message.

      Computes an arithmetic binary (two objects) operation on two domain
      objects. The default operator is add.
      The input objects are read from stdin and values are written to stdout
      unless the filenames are given.

      Example: cat obj1.wlz | %s -o obj3.wlz -a - obj2.wlz
      A new object 'obj3.wlz is formed by adding the grey values of obj1 and
      obj2.wlz.
