Synopsis

Class SubImage has to be used to apply a region or mask to an image. Several functions are inherited from SubLattice and not declared in this class.

Using an AxesSpecifier object it is possible to remove some or all degenerate axes (i.e. axes with length 1) to get an image with a lower dimensionality.

Constructor & Destructor Documentation

◆ SubImage() [1/8]

template<class T >

casacore::SubImage< T >::SubImage ( )

The default constructor.

◆ SubImage() [2/8]

template<class T >

casacore::SubImage< T >::SubImage	(	const ImageInterface< T > &	image,
		AxesSpecifier	= `AxesSpecifier()`,
		Bool	preserveAxesOrder = `False`
	)

Create a SubImage from a Image.

This results in a SubImage without a real mask.
The "const Image" version yields a non-writable SubImage, while for the non-const version one has to specify if the SubImage should be writable (if the original image is non-writable, the SubImage is always set to non-writable).
If preserveAxesOrder is True, the axes order will be preserved. This is only important in cases where pixel axes are to be dropped, if not the axes order will be preserved. If False and pixel axes are dropped, the order of the coordinates will be preserved, but not necessarily the axes.

◆ SubImage() [3/8]

template<class T >

casacore::SubImage< T >::SubImage	(	ImageInterface< T > &	image,

		AxesSpecifier	= `AxesSpecifier()`,

Set the coordinates.

It removes world axes if the subimage has axes removed.
If preserveAxesOrder is True and axes are dropped, it will preserve the order of the axes as well as the order of the coordinates.

◆ setMembers() [1/2]

template<class T >

void casacore::SubImage< T >::setMembers ( )

private

Set the other members to the one in itsImagePtr.

◆ setMembers() [2/2]

template<class T >

void casacore::SubImage< T >::setMembers ( const Slicer & slicer )

private

Set the members to the subset (in particular, the beamset).

◆ shape()

template<class T >

virtual IPosition casacore::SubImage< T >::shape ( ) const

virtual

Returns the shape of the SubImage including all degenerate axes (i.e.

axes with a length of one).

Implements casacore::LatticeBase.

◆ tempClose()

template<class T >

virtual void casacore::SubImage< T >::tempClose ( )

virtual

Temporarily close the lattice.

It will be reopened automatically on the next access.
By default the function does not do anything at all.

Reimplemented from casacore::LatticeBase.

◆ unlock()

template<class T >

virtual void casacore::SubImage< T >::unlock ( )

virtual

Reimplemented from casacore::LatticeBase.
