ZoomMap
-
Zoom coordinates about the origin
- Description:
- The ZoomMap class implements a Mapping which performs a "zoom"
transformation by multiplying all coordinate values by the same
scale factor (the inverse transformation is performed by
dividing by this scale factor). The number of coordinate values
representing each point is unchanged.
- Constructor Function:
- AST_ZOOMMAP
-
Inheritance
- The ZoomMap class inherits from the Mapping class.
-
Attributes
- In addition to those attributes common to all Mappings, every
ZoomMap also has the following attributes:
- Zoom: ZoomMap scale factor
-
Functions
- The ZoomMap class does not define any new routines beyond those
which are applicable to all Mappings.
