utility funtions to retrieve blc/trc of the handle or the handle corners

virtual Double casa::DDDHandle::blcY ( ) const [virtual]

void casa::DDDHandle::createHandle	(	Double	x,
		Double	y
	)

set up the handle

void casa::DDDHandle::createHandle ( const Vector< Double > & point )

References itsCorners.

virtual void casa::DDDHandle::move	(	Double	dx,
		Double	dy
	)		`[virtual]`

move the handle to a new position

void casa::DDDHandle::operator= ( const DDDHandle & )

virtual void casa::DDDHandle::resize ( const DDDHandle::Size & size ) [virtual]
