Classes
class	lsst::jointcal::Gtransfo
	a virtual (interface) class for geometric transformations. More...
class	lsst::jointcal::GtransfoIdentity
	A do-nothing transformation. It anyway has dummy routines to mimick a Gtransfo. More...
class	lsst::jointcal::GtransfoPoly
	Polynomial transformation class. More...
class	lsst::jointcal::GtransfoLin
	implements the linear transformations (6 real coefficients). More...
class	lsst::jointcal::GtransfoLinShift
	just here to provide a specialized constructor, and fit. More...
class	lsst::jointcal::GtransfoLinRot
	just here to provide a specialized constructor, and fit. More...
class	lsst::jointcal::GtransfoLinScale
	just here to provide specialized constructors. GtransfoLin fit routine. More...
class	lsst::jointcal::GtransfoSkyWcs
	A Gtransfo that holds a SkyWcs. More...
class	lsst::jointcal::BaseTanWcs
class	lsst::jointcal::TanPix2RaDec
	the transformation that handles pix to sideral transfos (Gnomonic, possibly with polynomial distortions). More...
class	lsst::jointcal::TanSipPix2RaDec
	Implements the (forward) SIP distorsion scheme. More...
class	lsst::jointcal::TanRaDec2Pix
	This one is the Tangent Plane (called gnomonic) projection (from celestial sphere to tangent plane) More...
class	lsst::jointcal::UserTransfo
	a run-time transfo that allows users to define a Gtransfo with minimal coding (just the transfo routine). More...

Typedefs
typedef void()	lsst::jointcal::GtransfoFun(const double, const double, double &, double &, const void *)
	signature of the user-provided routine that actually does the coordinate transfo for UserTransfo. More...

Functions
std::ostream &	lsst::jointcal::operator<< (std::ostream &stream, const Gtransfo &gtransfo)

bool	lsst::jointcal::isIdentity (const Gtransfo *gtransfo)
	Shorthand test to tell if a transfo belongs to the GtransfoIdentity class. More...
bool	lsst::jointcal::isIntegerShift (const Gtransfo *gtransfo)
	Shorthand test to tell if a transfo is a simple integer shift. More...
std::unique_ptr< GtransfoPoly >	lsst::jointcal::inversePolyTransfo (const Gtransfo &Direct, const Frame &frame, const double Prec)
	approximates the inverse by a polynomial, up to required precision. More...
GtransfoLin	lsst::jointcal::normalizeCoordinatesTransfo (const Frame &frame)
	Returns the transformation that maps the input frame along both axes to [-1,1]. More...
std::unique_ptr< Gtransfo >	lsst::jointcal::gtransfoRead (const std::string &fileName)
	The virtual constructor from a file. More...
std::unique_ptr< Gtransfo >	lsst::jointcal::gtransfoRead (std::istream &s)
	The virtual constructor from a file. More...
