Spatial Transformations
Version 3.0 adds functions for applying a variety of spatial transformations to
images and to points. This is a core computational capability. Supported
transform types include affine, projective, and user-defined custom
transformations. Multidimensional transformations are supported, where you
can control which dimensions are the transform dimensions. For example, you
can apply a two-dimensional transform to an RGB image, and each color plane
is automatically transformed the same way. You can even control the type of
