178 double newPointSize = qBound(12.0, factor * m_stdFont.pointSizeF(), 18.0) * (1.0 + 0.7 * Options::labelFontScaling()/100.0);
227void SkyLabeler::getMargins(const QString &text, float *left, float *right, float *top, float *bot)
QPointF toScreen(const SkyPoint *o, bool oRefract=true, bool *onVisibleHemisphere=nullptr) const
This is exactly the same as toScreenVec but it returns a QPointF.
Definition projector.cpp:93
bool onScreen(const QPointF &p) const
Check whether the projected point is on-screen.
Definition projector.cpp:98
The purpose of this class is to prevent labels from overlapping.
Definition skylabeler.h:99
bool markText(const QPointF &p, const QString &text, qreal padding_factor=1)
tells the labeler the location and text of a label you want to draw.
Definition skylabeler.cpp:408
void resetFont()
sets the font in SkyLabeler and in psky back to the zoom dependent value that was set in reset().
Definition skylabeler.cpp:222
void shrinkFont(int delta)
decreases the size of the font in psky and in the SkyLabeler by the delta points.
Definition skylabeler.cpp:206
void setZoomFont()
adjusts the font in psky to be smaller if we are zoomed out.
Definition skylabeler.cpp:44
bool markRegion(qreal left, qreal right, qreal top, qreal bot)
Works just like markText() above but for an arbitrary rectangular region bounded by top,...
Definition skylabeler.cpp:425
void setFont(const QFont &font)
tells the labeler the font you will be using so it can figure out the height and width of the labels.
Definition skylabeler.cpp:187
void reset(SkyMap *skyMap)
clears the virtual screen (if needed) and resizes the virtual screen (if needed) to match skyMap.
Definition skylabeler.cpp:250
void getMargins(const QString &text, float *left, float *right, float *top, float *bot)
sets four margins for help in keeping labels entirely on the screen.
Definition skylabeler.cpp:227
bool drawGuideLabel(QPointF &o, const QString &text, double angle)
Tries to draw the text at the position and angle specified.
Definition skylabeler.cpp:112
void addLabel(SkyObject *obj, label_t type)
queues the label in the "type" buffer for later drawing.
Definition skylabeler.cpp:577
void setPen(const QPen &pen)
sets the pen used for drawing labels on the sky.
Definition skylabeler.cpp:197
float hitRatio()
diagnostic, the number of times mark() returned true divided by the total number of times mark was ca...
Definition skylabeler.cpp:676
void useStdFont()
sets the font in SkyLabeler and in psky to the font psky had originally when reset() was called.
Definition skylabeler.cpp:217
void printInfo()
diagnostic, prints some brief statistics to the console.
Definition skylabeler.cpp:683
void drawQueuedLabelsType(SkyLabeler::label_t type)
a convenience routine that draws all the labels from a single buffer.
Definition skylabeler.cpp:633
void drawRudeNameLabel(SkyObject *obj, const QPointF &_p)
draw the object's name label on the map, without checking for overlap with other labels.
Definition skylabeler.cpp:647
bool drawNameLabel(SkyObject *obj, const QPointF &_p, const qreal padding_factor=1)
Tries to draw a label for an object.
Definition skylabeler.cpp:161
Provides all necessary information about an object in the sky: its coordinates, name(s),...

PI is a const static member; it's public so that it can be used anywhere, as long as dms....
