Base class for feedback objects to be used for cancellation of something running in a worker thread.
Definition qgsfeedback.h:45
Inverse distance weight interpolator.
double distanceCoefficient() const
Returns the distance coefficient, the parameter that sets how the values are weighted with distance.
void setDistanceCoefficient(double coefficient)
Sets the distance coefficient, the parameter that sets how the values are weighted with distance.
Interface class for interpolations.
virtual int interpolatePoint(double x, double y, double &result, QgsFeedback *feedback=nullptr)=0
Calculates interpolation value for map coordinates x, y.
