Detailed Description

Provide script API for Stellarium global functions.

Public slots in this class may be used in Stellarium scripts, and are accessed as member function to the "core" scripting object. Module-specific functions, such as setting and clearing of display flags (e.g. LandscapeMgr::setFlagAtmosphere) can be accessed directly via the scripting object with the class name, e.g. by using the scripting command: LandscapeMgr.setFlagAtmosphere(true);

slot

Load an image into the sky background at the given sky coordinates and be warped with the sky.

The image is projected like a deep-sky object, with a notion for surface magnitude of the brightest parts. Transparent sections in the image are possibly rendered white, so make your image just RGB with black background. The black background covers the milky way, but is brightened by the Zodiacal light.

Parameters

id	a string ID to be used when referring to this image (e.g. when changing the displayed status or deleting it.
filename	the file name of the image. If a relative path is specified, "scripts/" will be prefixed before the image is searched for using StelFileMgr.
lon0	The right ascension/longitude/azimuth of the first corner of the image in degrees (bottom left)
lat0	The declination/latitude/altitude of the first corner of the image in degrees (bottom left)

Note

since 2017-03, you can select Frame now.

Images in AzAlt frame are not affected by atmosphere effects like refraction or extinction.

Parameters

dateStr

the date string to use. Formats: ISO, e.g. "2008-03-24T13:21:01" "now" (set sim time to real time) relative, e.g. "+ 4 days", "-2 weeks". can use these units: seconds, minutes, hours, days, weeks, months, years. You may also append " sidereal" to use sidereal days and so on. You can also use "now" at the start. For example: "now + 3 hours sidereal"

Note

you must use the plural all the time, even when the number of the unit is 1. i.e. use "+ 1 days" not "+1 day".

when sidereal time is used, the length of time for each unit is dependent on the current planet. By contrast when sidereal time is not specified (i.e. solar time is used) the value is conventional - i.e. 1 day means 1 Earth Solar day.

Parameters

spec	"local" or "utc" - only has an effect when the ISO date type is used. Defaults to "utc".

for fully compatibles behavior of this function with the version 0.11.4 or earlier, you should call core.setDeltaTAlgorithm("WithoutCorrection"); before running core.setDate(); for disabling DeltaT correction.

starting with version 0.13.2 all relative dates are set without DeltaT correction.

starting with version 0.14.0 the final optional Boolean argument has a different meaning and default!

dateIsTT

true if the given date is formulated in Dynamical Time, i.e. with DeltaT added.
