lsst::geom::AffineTransform const & | transform |
transform object | |
A temporary-only expression object for ellipse transformations.
Transformer simply provides a clean syntax for transform-related operations, including in-place and new-object transformations, derivatives of the transformations, and implicit conversion to an auto_ptr to a new transformed ellipse.
