The feature class encapsulates a single feature including its unique ID, geometry and a list of field...
Definition: qgsfeature.h:56
A fill symbol type, for rendering Polygon and MultiPolygon geometries.
Definition: qgsfillsymbol.h:30
Contains information about the context of a rendering operation.
Abstract base class for all rendered symbols.
Definition: qgssymbol.h:38
virtual QgsSymbol * clone() const =0
Returns a deep copy of this symbol.
double ANALYSIS_EXPORT angle(QgsPoint *p1, QgsPoint *p2, QgsPoint *p3, QgsPoint *p4)
Calculates the angle between two segments (in 2 dimension, z-values are ignored)
