The input images must all be of the same +dimension and size. + +The output image inherits the world coordinate system (WCS) of the first +input image. If the dimension of the input image WCS is greater than or +equal to the dimension of the output image, the input WCS is copied to the +output image WCS without modification. Otherwise the input image WCS +dimension is incremented by 1 and copied to the output image WCS, the input +WCS coordinate transformations for each input image axis are copied to the +output image WCS without modification, and the new output image axis is +assigned a WCS type of 'linear' and the identity transformation. + +.ih +EXAMPLES + +1.
