Detailed Description

template<class T>
class casacore::ImageInterface< T >

A base class for astronomical images.

Intended use:

Public interface

Prerequisite

Etymology

The ImageInterface class name is derived from its role as the cookie cutter Interface base class for Images.

Synopsis

The ImageInterface class is an abstract base class. All Image classes should derive from this class to ensure functions which operate on Images will work for all Image derivations.

An Image is currently defined as an Array of pixels, a Boolean mask, defining which pixels are valid and coordinates to define the reference frame. The only concrete class currently derived from this Interface is PagedImage, which allows the image to be stored on disk, and only reads specified portions of the image into memory.

Example

As this is an abstract base class it is not possible to construct an instance of this object. It can however be used as a function argument.
eg 1. (used in dImageInterface.cc)

Float sumPixels(const ImageInterface<Float>& image){
uInt rowLength = image.shape()(0);
IPosition rowShape(image.ndim());
rowShape = 1; rowShape(0) = rowLength;
Float sumPix = 0;
RO_LatticeIterator<Float> iter(image, rowShape);
while(!iter.atEnd()){
sumPix += sum(iter.vectorCursor());
iter++;
}
return sumPix;
}

The main purpose of this class is for programming objects, the following example is of how one would derive from ImageInterface:
eg 2.

template <class T> class myNewImage : public ImageInterface<T>
{
public:
// default constructor
myNewImage();
// argumented constructor
myNewImage(...);
// destructor
~myNewImage
// the shape function is forced upon us by the Lattice base class
IPosition shape() const;
// doGetSlice is another function required of all Lattice objects.
Bool doGetSlice(<Array<T>& buffer, const Slicer& section);
// etc..\.
private:
// put the actual map data down here.
// etc..\.
};

Motivation

The use of abstract base classes to guide inheritance seemed appropriate for Images to ensure that CoordinateSystems and masking get handled uniformly.

To Do

replace ImageCoordinates

virtual Bool casacore::ImageInterface< T >::setCoordinateInfo ( const CoordinateSystem & coords )

virtual

Functions to set or replace the coordinate information in the Image Returns False on failure, e.g.

if the number of axes do not match.

Reimplemented in casacore::PagedImage< T >, and casacore::HDF5Image< T >.

template<class T>

void casacore::ImageInterface< T >::setCoordsMember ( const CoordinateSystem & coords )

inlineprotected

Set the coordinate system variable.

template<class T>

virtual void casacore::ImageInterface< T >::setDefaultMask ( const String & regionName )

virtual

Set the default pixelmask to the mask with the given name (which has to exist in the "masks" group).

If the image table is writable, the setting is persistent by writing the name as a keyword. If the given regionName is the empty string, the default pixelmask is unset.
