Detailed Description

The letter class for image coordinates.

Intended use:

Internal

Review Status

Date Reviewed:

yyyy/mm/dd

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 casa::LELImageCoord::classname

(

)

const [virtual]

The name of the class.

Reimplemented from casa::LELLattCoord.

virtual Int casa::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 casa::LELLattCoord.

const CoordinateSystem & casa::LELImageCoord::coordinates

(

)

const [inline]

Get the coordinates.

Definition at line 148 of file LELImageCoord.h.

References coords_p.

virtual Int casa::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 casa::LELLattCoord.

virtual uInt casa::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 casa::LELLattCoord.

virtual Bool casa::LELImageCoord::hasCoordinates

(

)

const [virtual]

The class has true coordinates (thus returns True).

Reimplemented from casa::LELLattCoord.

const ImageInfo & casa::LELImageCoord::imageInfo

(

)

const [inline]

Get the ImageInfo.

Definition at line 153 of file LELImageCoord.h.

References imageInfo_p.

virtual LatticeExprNode casa::LELImageCoord::makeExtendLattice	(	const LatticeExprNode &	expr,
		const IPosition &	newShape,
		const LELLattCoordBase &	newCoord
	)		const [virtual]

Create an extension for an expression node.

Reimplemented from casa::LELLattCoord.

virtual LatticeExprNode casa::LELImageCoord::makeRebinLattice	(	const LatticeExprNode &	expr,
		const IPosition &	binning
	)		const [virtual]

Create a rebinning for an expression node.

Reimplemented from casa::LELLattCoord.

virtual LatticeExprNode casa::LELImageCoord::makeSubLattice	(	const LatticeExprNode &	expr,
		const LattRegionHolder &	region
	)		const [virtual]

Create a SubLattice for an expression node.

Reimplemented from casa::LELLattCoord.

const TableRecord & casa::LELImageCoord::miscInfo

(

)

const [inline]

Get the MiscInfo.

Definition at line 163 of file LELImageCoord.h.

References miscInfo_p.

const Unit & casa::LELImageCoord::unit

(

)

const [inline]

Get the brightness unit.

Definition at line 158 of file LELImageCoord.h.

References unit_p.
