template<typename T >

lsst::gauss2d::python::Image< T >::Image ( py::array_t< T > data, const std::shared_ptr< const lsst::gauss2d::CoordinateSystem > coordsys = nullptr )

inlineexplicit

Construct an image from a numpy array.

Parameters

data	The numpy array to storage the image data.
coordsys	The coordinate system.

Note

Using this constructor will allow leave memory management on the Python side.

repr()

std::string lsst::gauss2d::Image< T, Image< T > >::repr ( bool name_keywords, std::string_view namespace_separator ) const

Return a full, callable string representation of this.

Parameters

name_keywords	Whether to prefix arguments with "{name}=", where name is the arg name in the header (as with keyword arguments in Python).
namespace_separator	The string to use to delimit namespaces, i.e. :: in C++ and . in Python.

Returns

A callable string representation of this, which should return an an identical object to this.

Note

The representation with name_keywords=false must be callable in C++. The representation with name_keywords=true should be callable in Python, if there are any bindings.
