Composite resources
The TransObj object class has no composite class resources.
Superclass resources
The superclass of the TransObj object class does not
define any resources.
Description
Objects belonging to the TransObj class provide
forward and reverse transformations for Transform
class plot objects. There are currently three subclasses of the
TransObj class:
- The LogLinTransObj provides transformations to and
from a linear or logarithmic coordinate space. Either or both coordinate
axes may be logarithmic.
- The IrregularTransObj provides transformations to
and from an irregularly-gridded rectangular coordinate space.
- The MapTransObj provides transformations to and from
any of 10 different standard map projections.
You do not instantiate any of these objects directly but several
Transform class plot objects allow you to access
their resources.
Support functions
There are no support functions defined for the TransObj
class or its superclass.
