Member Function Documentation

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

Contour using pgconb function.

(contour with blanks)

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

Contour using pgcont function.

virtual Int casa::WCPGFilter::pgid

(

)

const [inline, virtual]

Return the PGPLOT device id.

Definition at line 91 of file WCPGFilter.h.

References itsPgPlotID.

Bool casa::WCPGFilter::realign

(

const 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
