Detailed Description

A "handle" is a four-point structure (usually a rectangle) that describes the boundaries in screen pixels that a RegionShape takes on a canvas.

In the future, this will be used for selecting/editing/moving/resizing shapes on the canvas using the mouse.

Constructor & Destructor Documentation

casa::RSHandle::RSHandle ( )

Constructor which makes an invalid handle.

casa::RSHandle::RSHandle	(	const vector< double > &	x,
		const vector< double > &	y,
		int	markerHeight = `DEFAULT_MARKER_HEIGHT`,
		const String &	markerColor = `DEFAULT_MARKER_COLOR`,
		Display::Marker	markerType = `DEFAULT_MARKER_TYPE`
	)

Constructor which takes x and y vectors.

x and y MUST be length 4 or the handle is invalid.

casa::RSHandle::RSHandle	(	const Vector< double > &	x,
		const Vector< double > &	y,
		int	markerHeight = `DEFAULT_MARKER_HEIGHT`,
		const String &	markerColor = `DEFAULT_MARKER_COLOR`,
		Display::Marker	markerType = `DEFAULT_MARKER_TYPE`
	)
