Bases: ABC

A container or factory for Transform objects that relates frames.

Parameters:

• in_frame (TypeVar(I, bound= Frame)) – Frame to transform from.

• out_frame (TypeVar(O, bound= Frame)) – Frame to transform to.

Return type:

Optional[Transform[TypeVar(I, bound= Frame), TypeVar(O, bound= Frame)]]
