Computes a displacement field as a compound array object from two given objects. The displacements are between pixels/voxels with the same grey value. If the values of one of the objects were set using WlzGreySetIncValues and the other object is the result of a spatial transformation of that object then the displacements field will capture the transformation. The dispplacement values map object 1 to object 2.
Examples
WlzCompDispIncGrey -o out.wlz obj.wlz obj_t.wlz
Creates a new object which is written to the file out.wlz. The output object is a compound array containing the displacements from obj.wlz to obj1.wlz.
