	Calculates the solar position and events for a given point and time.

Detailed Description

Calculates the sun's position and related sun events for a given datetime.

This class is a high-level wrapper around the freespa algorithm for calculating solar position and events.

Warning: This class only supports sun position calculation from the Earth. Other celestial bodies are not supported.

static

Calculates the solar position and events for a given point and time.

Parameters

point	the target point in the specified crs.
crs	Coordinate Reference System associated with the point.
context	coordinate transform context.
dateTime	the date and time for the calculation.
elevationMeters	optional elevation of the observer in meters above sea level.
pressure	atmospheric pressure used for refraction correction (in millibars, hPa). The default is one standard atmosphere, or 1013.25 hPa.
temperature	the local temperature used for refraction correction, in degrees Celsius.

Returns: A QgsSunPositionResult containing the calculated solar angles and event times.

Warning: This method only supports sun position calculation from the Earth. Other celestial bodies are not supported.

Exceptions

QgsCsException	if the point could not be transformed to WGS84
QgsInvalidArgumentException	when the specified arguments are invalid
