Source Code for Package topo.coordmapperfns

 1  """ 
 2  A family of function objects for transforming one set of coordinates into 
 3  another. 
 4   
 5  Coordinate mapper functions are useful for defining magnifications and 
 6  other kinds of transformations on sheet coordinates, e.g. for defining 
 7  retinal magnification using a CFProjection.  A CoordinateMapperFn 
 8  (e.g. MagnifyingMapper), is applied to an (x,y) pair and returns a new 
 9  (x,y) pair.  To apply a mapping to a CF projection, set the 
10  CFProjection's coord_mapper parameter to an instance of the desired 
11  CoordinateMapperFn.
