Interface class for interpolations.
Inverse distance weight interpolator.
Base class for feedback objects to be used for cancelation of something running in a worker thread...
Definition: qgsfeedback.h:44
virtual int interpolatePoint(double x, double y, double &result, QgsFeedback *feedback=nullptr)=0
Calculates interpolation value for map coordinates x, y.
void setDistanceCoefficient(double coefficient)
Sets the distance coefficient, the parameter that sets how the values are weighted with distance...
#define SIP_OUT
Definition: qgis_sip.h:51
double distanceCoefficient() const
Returns the distance coefficient, the parameter that sets how the values are weighted with distance...
