Detailed Description

A coordinate system specifying image scale and orientation.

This is intended to mimic some of the functionality of e.g. basic FITS headers, in order for evaluators to draw images at different scales and/or with rotation/translation. Rotation is not yet supported.

repr()

std::string lsst::gauss2d::CoordinateSystem::repr ( bool name_keywords = false, std::string_view namespace_separator = Object::CC_NAMESPACE_SEPARATOR ) const

overridevirtual

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.
