Member Function Documentation

virtual boost::shared_ptr< XYTransform > lsst::afw::geom::AffineXYTransform::clone ( ) const

virtual

returns a deep copy

Implements lsst::afw::geom::XYTransform.

virtual Point2D lsst::afw::geom::AffineXYTransform::forwardTransform ( Point2D const & point ) const

virtual

virtuals for forward and reverse transforms

These routines are responsible for throwing exceptions if the 'point' arg is outside the domain of the transform.

Implements lsst::afw::geom::XYTransform.

AffineTransform lsst::afw::geom::AffineXYTransform::getForwardTransform ( ) const

get underlying forward AffineTransform

AffineTransform lsst::afw::geom::AffineXYTransform::getReverseTransform ( ) const

get underlying reverse AffineTransform

virtual AffineTransform lsst::afw::geom::AffineXYTransform::linearizeForwardTransform ( Point2D const & point ) const

virtual

linearized forward and reversed transforms

These are virtual but not pure virtual; there is a default implementation which calls forwardTransform() or reverseTransform() and takes finite differences with step size equal to one.

The following should always be satisfied for an arbitrary Point2D p (and analogously for the reverse transform) this->forwardTransform(p) == this->linearizeForwardTransform(p)(p);
