Functions
Eigen::Matrix2d	lsst::afw::geom::makeCdMatrix (lsst::geom::Angle const &scale, lsst::geom::Angle const &orientation=0 *lsst::geom::degrees, bool flipX=false)
	Make a WCS CD matrix.
std::shared_ptr< SkyWcs >	lsst::afw::geom::makeFlippedWcs (SkyWcs const &wcs, bool flipLR, bool flipTB, lsst::geom::Point2D const &center)
	Return a copy of a FITS-WCS with pixel positions flipped around a specified center.
std::shared_ptr< SkyWcs >	lsst::afw::geom::makeModifiedWcs (TransformPoint2ToPoint2 const &pixelTransform, SkyWcs const &wcs, bool modifyActualPixels)
	Create a new SkyWcs whose pixels are transformed by pixelTransform, as described below.
std::shared_ptr< SkyWcs >	lsst::afw::geom::makeSkyWcs (daf::base::PropertySet &metadata, bool strip=false)
	Construct a SkyWcs from FITS keywords.
std::shared_ptr< SkyWcs >	lsst::afw::geom::makeSkyWcs (lsst::geom::Point2D const &crpix, lsst::geom::SpherePoint const &crval, Eigen::Matrix2d const &cdMatrix, std::string const &projection="TAN")
