Detailed Description

template<class T>
class casacore::TempImage< T >

Temporary astronomical images.

Intended use:

Public interface

Review Status

Test programs:: tTempImage

Prerequisite

Etymology

The TempImage name comes from its role as the Image class for temporary storage.

Synopsis

The class TempImage is useful for storing temporary images for which it is not known whether they can be held in memory. It uses class TempLattice to hold the image in memory when it is small enough. Otherwise it is held in a temporary file. Similarly to TempLattice one can give the maximum memory to use to control when the image can be held in memory.
The other Image information like coordinates, units, and miscinfo is held in member variables and disappears when the TempImage object is destructed.

It is possibly to temporarily close a TempImage, which only takes effect when it is created as a PagedArray. In this way it is possible to reduce the number of open files in case a lot of TempImage objects are used. A temporarily closed TempImage will be reopened automatically when needed. It can also be reopened explicitly.

Example

Motivation

The size of astronomical data can be very large. The ability to fit an entire image into random access memory cannot be guaranteed. Paging from disk pieces of the image appeared to be the way to deal with this problem.

Constructor & Destructor Documentation

template<class T>

casacore::TempImage< T >::TempImage ( )

The default constructor creates an empty image.

template<class T>

casacore::TempImage< T >::TempImage	(	const TiledShape &	mapShape,
		const CoordinateSystem &	coordinateInfo,
		Int	maxMemoryInMB = `-1`
	)

Construct a temporary Image from shape and coordinate information.

If the image is sufficiently small, it is kept in memory. Otherwise it is kept in a temporary disk table. It can be forced to disk by setting maxMemoryinMB=0. The algorithm is the same as in class TempLattice.

casacore::TempImage< T >::TempImage	(	const TiledShape &	mapShape,

template<class T>

Member Function Documentation

template<class T>

virtual uInt casacore::TempImage< T >::advisedMaxPixels ( ) const

virtual

Returns the maximum recommended number of pixels for a cursor.

This is the number of pixels in a tile.

Reimplemented from casacore::Lattice< T >.

template<class T>

virtual void casacore::TempImage< T >::apply ( T(*)(T) function )

virtual

Replace every element, x, of the lattice with the result of f(x).

You must pass in the address of the function – so the function must be declared and defined in the scope of your program. Both versions of apply require a function that accepts a single argument of type T (the Lattice template actual type) and returns a result of the same type. The first apply expects a function with an argument passed by value; the second expects the argument to be passed by const reference. The first form ought to run faster for the built-in types, which may be an issue for large images stored in memory, where disk access is not an issue.
