Detailed Description

Implementation of an ellipse/rectangle object for DrawingDisplayData class.

Synopsis

This class implements the interface defined by DDDObject, to provide an ellipse or rectangle object for registration with DrawingDisplayData objects. The widths are all full widths.

Definition at line 69 of file DDDEllipse.h.

Constructor & Destructor Documentation

casa::DDDEllipse::DDDEllipse	(	const casacore::Record &	description,
		DrawingDisplayData *	owner
	)

Constructor taking a casacore::Record description.

Fields in the record, on top of what is consumed by the DDDObject constructor, are: Required : center (vector of quanta length 2), major, minor, positionangle (all quanta).

Units 'frac' ([0->1]) are available for the center only. Units 'pix' (absolute 0-rel image pixels) are available for the major and minor only.

Other, not required fields are outline & editable which default to true. When editable=false the object can be moved but not reshaped, when true it can be moved and reshaped. When outline=false the ellipse is filled. If the field rectangle=true a rectangle is drawn. If it does not exist or is false, an ellipse is drawn.

Finally, field doreference which defaults to false is used to control the location at which conversions to and from pixel coordinates are done. If true then all conversions are done at the reference value. Otherwise, the conversions are done at the actual location of the shape. For example, with a casacore::DirectionCoordinate plane, setting doreference=true will cause the shape to rotate as you move it about the display as the position angle tracks the local North.
