Indirectly Conformal Mapping

An indirectly conformal mapping, sometimes called an anticonformal mapping, is a mapping that reverses all angles, whereas an isogonal mapping can reverse some angles and preserve others.

For example, if  is a conformal map, then  is an indirectly conformal map, and  is an isogonal mapping.
