Class representing Printing Wizard for KStars printed documents (currently only finder charts).
void captureFov()
Capture current contents of FOV symbol.
bool calculatePath(const SkyPoint &src, const SkyPoint &dest, double fov, double maglim)
Calculate path between source and destination SkyPoints.
bool exportPath()
Export FOV snapshots across calculated path.
ShFovExporter(PrintingWizard *wizard, SkyMap *map)
Constructor.
This is the canvas on which the sky is painted.
Definition skymap.h:54
void setClickedPoint(const SkyPoint *f)
Set the ClickedPoint to the skypoint given as an argument.
Definition skymap.cpp:1012
void forceUpdate(bool now=false)
Recalculates the positions of objects in the sky, and then repaints the sky map.
Definition skymap.cpp:1177

QList< StarObject * > * computePath(const SkyPoint &src, const SkyPoint &dest, float fov__, float maglim__, QStringList *metadata_=nullptr)
Computes path for Star Hop.
Highlights objects present in certain lists by drawing "target" symbols around them.
std::unique_ptr< SkyObjectList > list
