class QgsInvertedPolygonRenderer : QgsMergedFeatureRenderer
{
%Docstring(signature="appended")
:py:class:`QgsInvertedPolygonRenderer` is a polygon-only feature
renderer used to display features inverted, where the exterior is turned
to an interior and where the exterior theoretically spans the entire
plane, allowing to mask the surroundings of some features.
It is designed on top of another feature renderer, which is called
"embedded" Most of the methods are then only proxies to the embedded
renderer.
Features are collected to form one "inverted" polygon during
:py:func:`~renderFeature` and rendered on :py:func:`~stopRender`.

public:
QgsInvertedPolygonRenderer( QgsFeatureRenderer *embeddedRenderer /Transfer/ = 0 );
%Docstring
Constructor
:param embeddedRenderer: optional embeddedRenderer. If ``None``, a
default one will be assigned. Ownership will be
transferred.
%End
virtual QgsInvertedPolygonRenderer *clone() const /Factory/;
virtual QString dump() const;
static QgsFeatureRenderer *create( QDomElement &element, const QgsReadWriteContext &context ) /Factory/;
%Docstring
Creates a renderer out of an XML, for loading
%End

bool preprocessingEnabled() const;
%Docstring
:return: ``True`` if the geometries are to be preprocessed (merged with
an union) before rendering.
%End
void setPreprocessingEnabled( bool enabled );
%Docstring
:param enabled: enables or disables the preprocessing. When enabled,
geometries will be merged with an union before being
rendered. It allows fixing some rendering artifacts
(when rendering overlapping polygons for instance). This
will involve some CPU-demanding computations and is thus
disabled by default.
%End
static QgsInvertedPolygonRenderer *convertFromRenderer( const QgsFeatureRenderer *renderer ) /Factory/;
%Docstring
Creates a QgsInvertedPolygonRenderer by a conversion from an existing
renderer.
:return: a new renderer if the conversion was possible, otherwise
``None``.
%End
