Prerequisite

LELLattCoord

Synopsis

This class is a letter class for the envelope class LELCoordinates . It acts as the coordinates class for Lattice objects with proper coordinates (like PagedImage).

Motivation

It must be possible to handle image coordinates in a lattice. expression.

Member Function Documentation

virtual String casacore::LELImageCoord::classname ( ) const [virtual]

The name of the class.

Reimplemented from casacore::LELLattCoord.

virtual Int casacore::LELImageCoord::compare ( const LELLattCoordBase & other ) const [virtual]

Check how the coordinates of this and that compare.

The return value tells how they compare.
-1: this is subset
0: equal
1: this is superset
9: invalid (mismatch)

Reimplemented from casacore::LELLattCoord.

const CoordinateSystem & casacore::LELImageCoord::coordinates ( ) const [inline]

Get the coordinates.

Definition at line 149 of file LELImageCoord.h.

References coords_p.

virtual Int casacore::LELImageCoord::doCompare ( const LELImageCoord & other ) const [virtual]

Check how the coordinates of this and that image compare.

This function is used by conform to make a double virtual dispatch possible.

virtual uInt casacore::LELImageCoord::getSpectralInfo	(	Vector< Double > &	worldCoordinates,
		const IPosition &	shape
	)			const `[virtual]`

Get the coordinates of the spectral axis for the given shape.

It returns the pixel axis number of the spectral coordinates. -1 indicates that there is no pixel spectral axis. An exception is thrown if there are no world spectral coordinates.

Reimplemented from casacore::LELLattCoord.

virtual Bool casacore::LELImageCoord::hasCoordinates ( ) const [virtual]

The class has true coordinates (thus returns True).

Reimplemented from casacore::LELLattCoord.

const ImageInfo & casacore::LELImageCoord::imageInfo ( ) const [inline]

Get the ImageInfo.

Definition at line 154 of file LELImageCoord.h.
