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.
|
slot |
Get the current shown status of a specified image.
id | the ID of the image whose status is desired. |
|
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
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. |
decimateBy | Allow image size reduction (e.g., 2...8) on very limited hardware |
QString StelSkyLayerMgr::insertSkyLayer | ( | StelSkyLayerP | l, |
const QString & | keyHint = QString() , |
||
bool | show = true |
||
) |
Add a new layer.
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 |
|
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.
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 |
withAberration | the image shall undergo aberration effects. Else it is really fixed to the frame. This flag is only used for images linked to FrameJ2000. |
decimateBy | allow texture reduction on loading, useful on very limited hardware. |
|
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.
key | the reference key (id) generated by insertSkyImage. |
|
slot |
Decide to show or not to show a layer by its ID.
id | the id of the layer whose status is to be changed. |
b | the new shown value:
