Prerequisite

• none

Etymology

"WCPGFilter" is a contraction and concatenation of "WorldCanvas," "PGPLOT" and "Filter", and is a simple filtering interface between the WorldCanvas and its PGPLOT driver.

Constructor & Destructor Documentation

casa::WCPGFilter::WCPGFilter

(

WorldCanvas *

wc

)

Constructor taking a pointer to a WorldCanvas.

virtual casa::WCPGFilter::~WCPGFilter ( )

virtual

Destructor.

void casa::WCPGFilter::conb	(	const casacore::Matrix< casacore::Float > &	m,
		const casacore::Vector< casacore::Float > &	levels,
		const casacore::Matrix< casacore::Float > &	tr,
		const casacore::Float	blank
	)

Contour using pgconb function.

(contour with blanks)

void casa::WCPGFilter::cont	(	const casacore::Matrix< casacore::Float > &	m,
		const casacore::Vector< casacore::Float > &	levels,
		const casacore::Matrix< casacore::Float > &	tr
	)

Contour using pgcont function.

virtual casacore::Int casa::WCPGFilter::pgid ( ) const

inlinevirtual

Return the PGPLOT device id.

References itsPgPlotID.

casacore::Bool casa::WCPGFilter::realign

(

const casacore::Bool &

linear = true

)

Realign the PGPLOT domain to the WorldCanvas domain.

If linear is false, then the pgplot canvas is setup to match the world coordinates, but of course is only valid where the world coordinates are linear to first approximation.

virtual void casa::WCPGFilter::ref ( )

void casa::WCPGFilter::splitContours ( casacore::Vector< casacore::Float > &  neg, casacore::Vector< casacore::Float > &  pos, const casacore::Vector< casacore::Float > &  levels  )
