Detailed Description

Re-sample Z for every feature (or a subset) as ONE undo step.

Snapshots the previous geometries; the whole resample reverts together because a partial revert would leave a layer with mixed vintages of terrain.

Constructor & Destructor Documentation

openswmmvis::map::ResampleZCommand::ResampleZCommand	(	FeatureLayer *	layer,
		const QVector< openswmmvis::feature::FeatureId > &	ids,
		MapCanvas *	canvas,
		QUndoCommand *	parent = `nullptr`
	)

Parameters

ids	Features to resample; empty means every feature.
