Detailed Description

Convenience functions for geometry editing.

Note: added in QGIS 2.10; this API is not considered stable and may change for 2.12; not available in Python bindings

Member Function Documentation

int QgsGeometryEditUtils::addPart	(	QgsAbstractGeometryV2 *	geom,
		QgsAbstractGeometryV2 *	part
	)

static

Adds part to multi type geometry (taking ownership)

Returns: 0 in case of success, 1 if not a multigeometry, 2 if part is not a valid geometry, 3 if new polygon ring not disjoint with existing polygons of the feature

Definition at line 103 of file qgsgeometryeditutils.cpp.

int QgsGeometryEditUtils::addRing	(	QgsAbstractGeometryV2 *	geom,
		QgsCurveV2 *	ring
	)

static

Adds interior ring (taking ownership).

Returns: 0 in case of success (ring added), 1 problem with geometry type, 2 ring not closed, 3 ring is not valid geometry, 4 ring not disjoint with existing rings, 5 no polygon found which contained the ring

Definition at line 29 of file qgsgeometryeditutils.cpp.

QgsAbstractGeometryV2 * QgsGeometryEditUtils::avoidIntersections	(	const QgsAbstractGeometryV2 &	geom,
		QMap< QgsVectorLayer *, QSet< QgsFeatureId > >	ignoreFeatures = `( QMap<QgsVectorLayer*, QSet<QgsFeatureId> >() )`
	)

static

Alters a geometry so that it avoids intersections with features from all open vector layers.

Parameters

geom	geometry to alter
ignoreFeatures	map of layer to feature id of features to ignore

Definition at line 226 of file qgsgeometryeditutils.cpp.

bool QgsGeometryEditUtils::deletePart	(	QgsAbstractGeometryV2 *	geom,
		int	partNum
	)

static

Deletes a part from a geometry.

Definition at line 210 of file qgsgeometryeditutils.cpp.

bool QgsGeometryEditUtils::deleteRing	(	QgsAbstractGeometryV2 *	geom,
		int	ringNum,
		int	partNum = `0`
	)

static

Deletes a ring from a geometry.
