Member Function Documentation

◆ addReliefColorClass()

void QgsRelief::addReliefColorClass ( const QgsRelief::ReliefColor color)

Definition at line 56 of file qgsrelief.cpp.

◆ calculateOptimizedReliefClasses()

QList< QgsRelief::ReliefColor > QgsRelief::calculateOptimizedReliefClasses ( )

Calculates class breaks according with the method of Buenzli (2011) using an iterative algorithm for segmented regression.

Returns
true in case of success

Definition at line 554 of file qgsrelief.cpp.
