Utility functions for use when clipping map renders.

public:
static QList< QgsMapClippingRegion > collectClippingRegionsForLayer( const QgsRenderContext &context, const QgsMapLayer *layer );
%Docstring
Collects the list of map clipping regions from a ``context`` which apply
to a map ``layer``.
%End
static QgsGeometry calculateFeatureRequestGeometry( const QList< QgsMapClippingRegion > ®ions, const QgsRenderContext &context, bool &shouldFilter );
%Docstring
Returns the geometry representing the intersection of clipping
``regions`` from ``context``.
The returned geometry will be automatically reprojected into the same
CRS as the source layer, ready for use for filtering a feature request.
:param regions: list of clip regions which apply to the layer
:param context: a render context
:param shouldFilter: will be set to ``True`` if layer's features should
be filtered, i.e. one or more clipping regions
applies to the layer
:return: combined clipping region for use when filtering features to
render
%End
static QgsGeometry calculateFeatureIntersectionGeometry( const QList< QgsMapClippingRegion > ®ions, const QgsRenderContext &context, bool &shouldClip );
%Docstring
Returns the geometry representing the intersection of clipping
``regions`` from ``context`` which should be used to clip individual
feature geometries prior to rendering.
The returned geometry will be automatically reprojected into the same
CRS as the source layer, ready for use for clipping features.
:param regions: list of clip regions which apply to the layer
:param context: a render context
:param shouldClip: will be set to ``True`` if layer's features should be
filtered, i.e. one or more clipping regions applies
to the layer
:return: combined clipping region for use when rendering features
%End
static QPainterPath calculatePainterClipRegion( const QList< QgsMapClippingRegion > ®ions, const QgsRenderContext &context, Qgis::LayerType layerType, bool &shouldClip );
%Docstring
Returns a QPainterPath representing the intersection of clipping
``regions`` from ``context`` which should be used to clip the painter
during rendering of a layer of the specified ``layerType``.
The returned coordinates are in painter coordinates for the destination
``context``.
:param regions: list of clip regions which apply to the layer
:param context: a render context
:param shouldClip: will be set to ``True`` if the clipping path should
be applied
:param layerType: the layer type to filter
:return: combined painter clipping region for use when rendering maps
%End
static QgsGeometry calculateLabelIntersectionGeometry( const QList< QgsMapClippingRegion > ®ions, const QgsRenderContext &context, bool &shouldClip );
%Docstring
Returns the geometry representing the intersection of clipping
``regions`` from ``context`` which should be used to clip individual
feature geometries while registering them with labeling engines.
The returned geometry will be automatically reprojected into the same
CRS as the source layer, ready for use for clipping features.
:param regions: list of clip regions which apply to the layer
:param context: a render context
:param shouldClip: will be set to ``True`` if layer's features should be
clipped for labeling, i.e. one or more clipping
regions applies to the layer
:return: combined clipping region for use when labeling features
