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.

Reimplemented from casacore::LELLattCoord.

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.

References imageInfo_p.

virtual LatticeExprNode casacore::LELImageCoord::makeExtendLattice ( const LatticeExprNode expr,
const IPosition newShape,
const LELLattCoordBase newCoord 
) const
virtual

Create an extension for an expression node.

Reimplemented from casacore::LELLattCoord.

virtual LatticeExprNode casacore::LELImageCoord::makeRebinLattice ( const LatticeExprNode expr,
const IPosition binning 
) const
virtual

Create a rebinning for an expression node.

Reimplemented from casacore::LELLattCoord.

virtual LatticeExprNode casacore::LELImageCoord::makeSubLattice ( const LatticeExprNode expr,
const LattRegionHolder region 
) const
virtual

Create a SubLattice for an expression node.

Reimplemented from casacore::LELLattCoord.

const TableRecord & casacore::LELImageCoord::miscInfo ( ) const
inline

Get the MiscInfo.

Definition at line 164 of file LELImageCoord.h.

References miscInfo_p.

const Unit & casacore::LELImageCoord::unit ( ) const
inline

Get the brightness unit.

Definition at line 159 of file LELImageCoord.h.

References unit_p.
