Prerequisite

Synopsis

Caution: All pixel coordinates are zero relative;

Example

In this example we create a QualityCoordinate containing 'DATA' and 'ERROR'

Vector<Int> newQuality(2);
newQuality(0) = Quality::DATA;
newQuality(1) = Quality::ERROR;
qual = QualityCoordinate(newQuality);

Constructor & Destructor Documentation

◆ QualityCoordinate() [1/3]

The length of whichQuality is the length of the axis, and the values define which quality are in which axis value.

Often the vector will be of length 2 and will contain Quality::DATA, and ERROR.

casacore::QualityCoordinate::QualityCoordinate ( const QualityCoordinate & other )

Copy constructor (copy semantics)

◆ ~QualityCoordinate()

virtual casacore::QualityCoordinate::~QualityCoordinate ( )

virtual

Destructor.

◆ QualityCoordinate() [3/3]

casacore::QualityCoordinate::QualityCoordinate ( )

private

Undefined and inaccessible.

Member Function Documentation

		Int	precision = `-1`,
		Bool	usePrecForMixed = `False`
	)		const

virtual

Format a QualityCoordinate world value with the common format interface (refer to the base class Coordinate for basics.

A QualityCoordinate is formatted differently from other Coordinate types. The world value is converted to the character representation as defined by the enum QualityTypes in the class Quality.

Thus, all other arguments to do with formatting and precision are ignored.

with the specified fractional tolerance. Don't compare on the specified
axes in the Coordinate. If the comparison returns False, method errorMessage returns a message about why.

◆ restore()

static QualityCoordinate* casacore::QualityCoordinate::restore	(	const RecordInterface &	container,

◆ save()

virtual Bool casacore::QualityCoordinate::save	(	RecordInterface &	container,
		const String &	fieldName
	)		const

virtual

Save the QualityCoordinate into the supplied record using the supplied field name.

virtual Bool casacore::QualityCoordinate::setWorldMixRanges ( const IPosition & shape )

virtual

Set the world min and max ranges, for use in function toMix, for a lattice of the given shape (for this coordinate).

The implementation here gives world coordinates at the start and end of the Quality axis. The output vectors are resized. Returns False if fails (and then setDefaultWorldMixRanges generates the ranges) with a reason in errorMessage(). The setDefaultWorldMixRanges function gives you [-1e99->1e99].

Reimplemented from casacore::Coordinate.

◆ showType()

virtual String casacore::QualityCoordinate::showType ( ) const

virtual

Always returns the String "Quality".

	)		const

◆ toWorld() [4/5]

static Double casacore::QualityCoordinate::toWorld ( Quality::QualityTypes quality )

static

Interconvert between world stored as a Double and world stored as a Quality type.

Since these functions are static, any valid Quality type can be used. The second function returns Quality::Undefined if world is illegal.

◆ toWorld() [5/5]

virtual Bool casacore::QualityCoordinate::toWorld	(	Vector< Double > &	world,
		const Vector< Double > &	pixel,
		Bool	= `True`
	)		const

virtual

Convert a pixel to a world coordinate or vice versa.

Returns True if the conversion succeeds, otherwise it returns False and method errorMessage returns an error message. The output vectors are appropriately resized before use. The Bool parameter in toWorld() is ignored as this coordinate does not support a conversion layer frame.

Implements casacore::Coordinate.

◆ type()
