Sampling interface
The pixel sampling depends on the current domain (`SPATIAL` or `FREQUENCY` ) and may change, e.g. after a fourier-transform. Domain-independent access to the sampling is provided by the Set/GetSpatialSampling methods. The IndexToCoord() and CoordToIndex() methods can be used for conversion between pixel values and coordinates; they honour the current domain.

Detailed Description

Abstract base class for read-only data.

This class represents the abstract concept of a read-only (const) data source which allows:

retrieving values based on triple integer indices
retrieving type, domain, and extent
applying NonModAlgorithms
(de-)attaching DataObservers
retrieving the spatial origin
retrieving pixel sampling

In addition, a meta-info (InfoHandle) is associated with this data
