Constructor & Destructor Documentation

QgsMeshContours::QgsMeshContours ( QgsMeshLayer * layer )

Constructs the mesh contours exporter.

Caches the native and triangular mesh from data provider

Parameters

layer mesh layer to be associated with this exporter

Definition at line 38 of file qgsmeshcontours.cpp.

QgsMeshContours::~QgsMeshContours ( )

default

QgsGeometry QgsMeshContours::exportLines	(	const QgsMeshDatasetIndex &	index,
		double	value,
		QgsMeshRendererScalarSettings::DataResamplingMethod	method,
		QgsFeedback *	feedback = `nullptr`
	)

Exports multi line string containing the contour line for particular dataset and value.

Parameters

index	dataset index
value	value of the contour line
method	for datasets defined on faces, the method will be used to convert data to vertices
feedback	optional feedback object for progress and cancellation support

QgsGeometry QgsMeshContours::exportPolygons	(	const QgsMeshDatasetIndex &	index,
		double	min_value,
		double	max_value,
		QgsMeshRendererScalarSettings::DataResamplingMethod	method,
		QgsFeedback *	feedback = `nullptr`
	)

Exports multi polygons representing the areas with values in range for particular dataset.

Parameters

index	dataset index
min_value	minimum of the value interval for contour polygon
max_value	maximum of the value interval for contour polygon
method	for datasets defined on faces, the method will be used to convert data to vertices
feedback	optional feedback object for progress and cancellation support
