Detailed Description

Manage the sky background images, including DSS and deep sky objects images.

Drawn after Milky Way, but before Zodiacal Light. It is not intended to be used to "overdraw" images into the foreground without a concept of surface magnitude.

Definition at line 36 of file StelSkyLayerMgr.hpp.

Member Function Documentation

virtual void StelSkyLayerMgr::draw ( StelCore * core )

virtual

Draws sky background.

Reimplemented from StelModule.

QStringList StelSkyLayerMgr::getAllKeys ( ) const

inlineslot

Return the list of all the layer currently loaded.

Definition at line 171 of file StelSkyLayerMgr.hpp.

QMap<QString, StelSkyLayerP> StelSkyLayerMgr::getAllSkyLayers ( ) const

Get the list of all the currently loaded layers.

virtual double StelSkyLayerMgr::getCallOrder ( StelModuleActionName actionName ) const

virtual

Determines the order in which the various modules are drawn.

Reimplemented from StelModule.

bool StelSkyLayerMgr::getFlagShow ( void ) const

inline

Get whether Sky Background should be displayed.

Definition at line 77 of file StelSkyLayerMgr.hpp.

bool StelSkyLayerMgr::getShowLayer ( const QString & id ) const

slot

Get the current shown status of a specified image.

Parameters

id	the ID of the image whose status is desired.

Returns

the current shown status of the specified image:

true means the specified image is currently shown.
false means the specified image is currently not shown.

virtual void StelSkyLayerMgr::init ( )

virtual

Initialize.

Implements StelModule.

QString StelSkyLayerMgr::insertSkyImage	(	const QString &	uri,
		const QString &	keyHint = `QString()`,
		bool	show = `true`
	)

slot

Add a new SkyImage from its URI (URL or local file name).

The image is owned by the manager and will be destroyed at the end of the program or when removeSkyImage is called with the same URI

Parameters

uri	the local file or the URL where the JSON image description is located.
keyHint	a hint on which key to use for later referencing the image.
show	defined whether the image should be shown by default.

Returns: the reference key to use when accessing this image later on.

QString StelSkyLayerMgr::insertSkyLayer	(	StelSkyLayerP	l,
		const QString &	keyHint = `QString()`,
		bool	show = `true`
	)

Add a new layer.

Parameters

l	the layer to insert.
keyHint	a hint on which key to use for later referencing the image.
show	defined whether the layer should be shown by default

Returns: the reference key to use when accessing this layer later on.

bool StelSkyLayerMgr::loadSkyImage	(	const QString &	id,
		const QString &	filename,
		double	long0,
		double	lat0,
		double	long1,
		double	lat1,
		double	long2,
		double	lat2,
		double	long3,
		double	lat3,
		double	minRes,
		double	maxBright,
		bool	visible,
		StelCore::FrameType	frameType = `StelCore::FrameJ2000`
	)

slot

Load an image from a file into a quad described with 4 corner coordinates.

The corners are always given in counterclockwise from top-left, also for azaltimuthal images. This should not be called directly from scripts because it is not thread safe. Instead use the similarly named function in the core scripting object.

Parameters

id	a string identifier for the image
filename	the name of the image file to load. Will be searched for using StelFileMgr, so partial names are fine.
lon0	right ascension/longitude/azimuth of top-left corner 0 in degrees
lat0	declination/latitude/altitude of corner 0 in degrees
lon1	right ascension/longitude/azimuth of bottom-left corner 1 in degrees
lat1	declination/latitude/altitude of corner 1 in degrees
lon2	right ascension/longitude/azimuth of bottom-right corner 2 in degrees
lat2	declination/latitude/altitude of corner 2 in degrees
lon3	right ascension/longitude/azimuth of top-right corner 3 in degrees
lat3	declination/latitude/altitude of corner 3 in degrees
minRes	the minimum resolution setting for the image
maxBright	the maximum brightness setting for the image
visible	initial visibility setting
frameType	Coordinate frame type

Note: Last argument has been added 2017-03. Use loadSkyImage(... , StelCore::FrameJ2000) for the previous behaviour!; For frameType=AzAlt, azimuth currently is counted from South towards East.

bool StelSkyLayerMgr::loadSkyImageAltAz	(	const QString &	id,
		const QString &	filename,
		double	alt0,
		double	azi0,
		double	alt1,
		double	azi1,
		double	alt2,
		double	azi2,
		double	alt3,
		double	azi3,
		double	minRes,
		double	maxBright,
		bool	visible
	)

slot

Load an image from a file into AzAltimuthal coordinates.

This should not be called directly from scripts because it is not thread safe. Instead use the similarly named function in the core scripting object.

Parameters

id	a string identifier for the image
filename	the name of the image file to load. Will be searched for using StelFileMgr, so partial names are fine.
alt0	altitude angle of corner 0 in degrees
azi0	azimuth angle of corner 0 in degrees
alt1	altitude angle of corner 1 in degrees
azi1	azimuth angle of corner 1 in degrees
alt2	altitude angle of corner 2 in degrees
azi2	azimuth angle of corner 2 in degrees
alt3	altitude angle of corner 3 in degrees
azi3	azimuth angle of corner 3 in degrees
minRes	the minimum resolution setting for the image
maxBright	the maximum brightness setting for the image
visible	initial visibility setting

Deprecated:: since 2017-03 (inconsistent parameter order)! Use loadSkyImage(...., StelCore::FrameAzAlt) instead!

void StelSkyLayerMgr::removeSkyLayer ( StelSkyLayerP l )

Remove a layer.

void StelSkyLayerMgr::removeSkyLayer ( const QString & key )

slot

Remove a sky layer from the list.

Note: this is not thread safe, and so should not be used directly from scripts - use the similarly named function in the core scripting API object to delete SkyLayers.

Parameters

key	the reference key (id) generated by insertSkyImage.

void StelSkyLayerMgr::setFlagShow ( bool b )

inlineslot

Set whether Sky Background should be displayed.

Definition at line 83 of file StelSkyLayerMgr.hpp.

void StelSkyLayerMgr::showLayer	(	const QString &	id,
		bool	b
	)

slot

Decide to show or not to show a layer by its ID.

Parameters

id	the id of the layer whose status is to be changed.
b	the new shown value: true means the specified image will be shown. false means the specified image will not be shown.

virtual void StelSkyLayerMgr::update ( double )

inlinevirtual

Update state which is time dependent.

Implements StelModule.
