Constructor & Destructor Documentation

◆ QgsTINInterpolator()

QgsTINInterpolator::QgsTINInterpolator ( const QList< QgsInterpolator::LayerData > &  inputData,
TINInterpolation  interpolation = Linear,
QgsFeedback feedback = nullptr 
)

Constructor for QgsTINInterpolator.

The feedback object specifies an optional QgsFeedback object for progress reports and cancelation support. Ownership of feedback is not transferred and callers must ensure that it exists for the lifetime of this object.

◆ ~QgsTINInterpolator()

QgsTINInterpolator::~QgsTINInterpolator ( )

Definition at line 44 of file qgstininterpolator.cpp.

Member Function Documentation

◆ interpolatePoint()

int QgsTINInterpolator::interpolatePoint ( double  x,
double  y,
double &  result 
)
overridevirtual

Calculates interpolation value for map coordinates x, y.

Parameters
xx-coordinate (in map units)
yy-coordinate (in map units)
resultout: interpolation result
Returns
0 in case of success

Implements QgsInterpolator.
