Member Enumeration Documentation

◆ FeatureClippingType

enum class QgsMapClippingRegion::FeatureClippingType : int

strong

Feature clipping behavior, which controls how features from vector layers will be clipped.

Enumerator
ClipToIntersection	Clip the geometry of these features to the region prior to rendering (i.e. feature boundaries will follow the clip region)
ClipPainterOnly	Applying clipping on the painter only (i.e. feature boundaries will be unchanged, but may be invisible where the feature falls outside the clipping region)
NoClipping	Only render features which intersect the clipping region, but do not clip these features to the region.

Constructor & Destructor Documentation

◆ QgsMapClippingRegion()

QgsMapClippingRegion::QgsMapClippingRegion ( const QgsGeometry & geometry )

inlineexplicit

Constructor for a map clipping region, with the specified geometry in the destination map CRS.

Definition at line 51 of file qgsmapclippingregion.h.

Member Function Documentation

◆ appliesToLayer()

bool QgsMapClippingRegion::appliesToLayer ( const QgsMapLayer * layer ) const

Returns true if the clipping region should be applied to the specified map layer.

Definition at line 40 of file qgsmapclippingregion.cpp.

◆ featureClip()

FeatureClippingType QgsMapClippingRegion::featureClip ( ) const

inline

Returns the feature clipping type.

This setting is only used while rendering vector layers, for other layer types it is ignored.

See also: setFeatureClip()

Definition at line 76 of file qgsmapclippingregion.h.

◆ geometry()

QgsGeometry QgsMapClippingRegion::geometry ( ) const

Returns the geometry of the clipping region (in the destination map CRS).

See also: setGeometry().

Definition at line 20 of file qgsmapclippingregion.cpp.

◆ restrictedLayers()

QList< QgsMapLayer * > QgsMapClippingRegion::restrictedLayers ( ) const

Returns the list of layers to restrict the clipping region effects to.

If the list is empty then the clipping will be applied to all layers.

Note: This setting is only used if restrictToLayers() is true.

See also: setRestrictedLayers(); restrictToLayers()

Definition at line 35 of file qgsmapclippingregion.cpp.

◆ restrictToLayers()

bool QgsMapClippingRegion::restrictToLayers ( ) const

Returns true if clipping should be restricted to a subset of layers.

See also: restrictedLayers(); setRestrictToLayers()

Definition at line 55 of file qgsmapclippingregion.cpp.

◆ setFeatureClip()

void QgsMapClippingRegion::setFeatureClip ( FeatureClippingType type )

inline

Sets the feature clipping type.

This setting is only used while rendering vector layers, for other layer types it is ignored.

See also: featureClip()

Definition at line 88 of file qgsmapclippingregion.h.

◆ setGeometry()

void QgsMapClippingRegion::setGeometry ( const QgsGeometry & geometry )

Sets the clipping region geometry (in the destination map CRS).

See also: geometry()

Definition at line 25 of file qgsmapclippingregion.cpp.

◆ setRestrictedLayers()

void QgsMapClippingRegion::setRestrictedLayers ( const QList< QgsMapLayer * > & layers )

Sets a list of layers to restrict the clipping region effects to.

By default the clipping region applies to all layers.

Note: This setting is only used if restrictToLayers() is true.

See also: restrictedLayers(); setRestrictToLayers()

Definition at line 30 of file qgsmapclippingregion.cpp.

◆ setRestrictToLayers()

void QgsMapClippingRegion::setRestrictToLayers ( bool enabled )

Sets whether clipping should be restricted to a subset of layers.

See also: setRestrictedLayers(); restrictToLayers()
